Reliability, validity, and responsiveness of pinch strength assessment: a systematic review.

PURPOSE: To summarize and critically appraise the quality of studies investigating psychometric properties of pinch strength assessment. METHODS: Medical literature up to February 2024 was searched for studies reporting on at least one measurement property of pinch strength assessment. The quality of the evidence and the risk of bias were rated using COSMIN 2018 guidelines. RESULTS: Thirty-three studies (1962 participants) were included. The majority (16/19) of reliability studies were of adequate to very good quality. Seven of 12 studies of validity were rated as adequate or very good. The quality of the eight responsiveness studies was adequate. Reliability was good to excellent (ICC > 0.75) for neurological conditions, and excellent (ICC > 0.90) for musculoskeletal disorders and healthy participants. Pinch strength showed strong to very strong correlations with grip strength (r = 0.72-0.92), moderate to strong correlations with assessments of dexterity (r = 0.78-0.80), and weak to moderate correlation with patient-reported outcome measures (r = 0.03-0.50). Varied results were found for pinch strength responsiveness in a small number of studies. CONCLUSIONS: Pinch strength assessment is reliable. Validity and responsiveness are less reported, but there is a strong correlation between pinch and grip strength, and a moderate correlation with dexterity.

This review demonstrated that the reliability of pinch strength assessment is good to excellent.Clinicians can measure pinch strength and expect accurate results over repeated measurements and between raters.There is a strong correlation between pinch and grip strength, and a moderate correlation between pinch strength and hand dexterity.The low correlation between pinch strength and patient-reported outcome measures highlights the need to measure these outcomes independently of each other.

Measures Determining Dementia-Related Attitudes in Adolescents: A Scoping Review.

Reducing stigma is a key benefit to intergenerational programs. However, little is known about the availability and suitability of measures that capture dementia-related attitudes in adolescents, thus limiting interpretations of the efficacy of such programs. The aim of this scoping review was to provide an overview of outcome measures used to capture dementiarelated attitudes in adolescents. Scoping review methodology was used to systematically identify relevant articles. Key search terms included dementia, attitudes, and adolescents. Fourteen studies met the inclusion criteria, of which 13 unique measures were identified. However, there are gaps in psychometric properties and a lack of underlying theoretical frameworks.

Psychometric properties of anxiety sensitivity Index-3 among Chinese college students and its preliminary application among this population experiencing campus lockdown.

PURPOSE: Anxiety sensitivity (AS) refers to fear of anxiety-related sensory arousal and has been revealed to be associated with increased psychological distress and mental problems. Although Anxiety Sensitivity Index-3 (ASI-3) has been confirmed to be effective in evaluating this construct, whether it is consistently applicable in college students is still elusive. The present study aimed to examine the psychometric properties and measurement invariance of Chinese version of ASI-3 (C-ASI-3) among college students experiencing campus lockdown due to novel coronavirus disease 2019 (COVID-19) pandemic. METHODS: A total of 1532 Chinese college students (397, 25.9% males) aged between 16 and 25 were included in this study. Confirmatory factor analysis (CFA) was used to verify the factor structure of C-ASI-3. Multi-group CFA was conducted for analysis of measurement invariance with regard to gender. McDonald's omega values were computed for examination of scale reliability. For criterion, convergent, and divergent validity, average variance extracted (AVE) values for C-ASI-3 subscales, difference between square root of AVE for each factor and inter-factor correlation, as well as pearson correlation and partial correlation between the C-ASI-3 and other three scales, including the Depression, Anxiety, and Stress Scale-21 (DASS-21), the State-Trait Anxiety Inventory (STAI), and the Fear of COVID-19 scale (FCV-19 S) were evaluated. RESULTS: The C-ASI-3 presented a three-factor scale structure with fit indices being as follows: χ2/df = 11.590, CFI = 0.938, RMSEA = 0.083, SRMR = 0.042. Strict measurement invariance was reached across gender. Regarding convergent validity, the C-ASI-3 had a high correlation with the DASS-21 (r = 0.597, p < 0.01) and the STAI (r = 0.504, p < 0.01). All AVE values for C-ASI-3 subscales were above 0.5. In terms of divergent validity, the C-ASI-3 had medium correlation with the FCV-19 S (r = 0.360, p < 0.01). Square of root of AVE for each factor was higher that inter-factor correlation. McDonald's omega values of the three dimensions ranged from 0.898 ~ 0.958. CONCLUSION: The C-ASI-3 has acceptable psychometric properties among college students. College students with different gender have consistent understanding on the scale construct.

Urdu translation and cross-cultural validation of the stroke self-efficacy questionnaire.

BACKGROUND: The Stroke Self-Efficacy Questionnaire (SSEQ) measures the self-confidence of the individual in functional activities after a stroke. The SSEQ is a self-report scale with 13 items that assess self-efficacy after a stroke in several functional domains. OBJECTIVE: The purpose was to translate the Stroke Self-Efficacy Questionnaire into Urdu Language and to find out the validity and reliability of Urdu SSEQ among stroke patients. METHODS: The cross-cultural validation study design was used. Following COSMIN guidelines, forward and backward translation protocols were adopted. After pilot testing on 10 stroke patients, the final Urdu version was drafted. A sample of 110 stroke patients was used to evaluate the validity and reliability of the SSEQ-U. Content and Concurrent validity were determined. The intraclass correlation coefficient and Cronbach's alpha were used to measure internal consistency and test-retest reliability. Data analysis was performed using SPSS 25. RESULTS: The final version was drafted after application on 10 stroke patients. Content validity was analyzed by a content validity index ranging from 0.87 to 1. The internal consistency was calculated by Cronbach's alpha (α > 0.80). Test-retest reliability was determined by the Intra-class correlation coefficient (ICC2,1=0.956). Concurrent validity was determined by correlations with other scales by using the Spearman correlation coefficient; moderate to strong correlations (positive and negative) were found with the Functional Independence Measure (r = 0.76), Beck Depression Inventory (r=-0.54), Short Form of 12-item Scale (r = 0.68) and Fall Efficacy Scale (r = 0.82) with p < 0.05. CONCLUSION: The Urdu version was linguistically acceptable and accurate for stroke survivors for determining self-efficacy. It showed good content and concurrent validity, internal consistency and test-retest reliability.

Cross-cultural adaptation, reliability, and validity of the Persian version of the overactive bladder questionnaire (OAB-V8).

Background and objectives: Overactive bladder (OAB) is characterized by urinary frequency and is recognized as a disorder. Various tools are available for diagnosing this condition. This study aimed to evaluate the reliability and validity of the Persian version of the 8-item Overactive Bladder Scale (OAB-V8). Methods: This analytical cross-sectional study was conducted on a sample of 150 OAB patients. The OAB-V8 scale was translated and culturally adapted following established guidelines. Face and content validity were assessed using the Impact Score (IS), Content Validity Index (CVI), and Content Validity Ratio (CVR) indices. Reliability was evaluated by calculating Cronbach's alpha (α) and utilizing the test-retest method (Intra-class correlation coefficients (ICC)). Construct validity was explored through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). All statistical analyses were carried out using SPSS version 24 and AMOS version 24, with a significance level set at 5 %. Results: The face validity was confirmed, with all items having an IS value greater than 1.5. Content validity was also confirmed, as most items had a Content Validity Index (CVI) higher than 0.79, and the average Content Validity Ratio (CVR) value was 0.96. In the initial phase of Exploratory Factor Analysis (EFA), the sample adequacy and suitability of the exploratory analysis were confirmed (Kaiser-Meyer-Olkin (KMO) test value = 0.784, Bartlett's Test p-value <0.05). Two dimensions explaining 61.87 % of the variance were then extracted. In the Confirmatory Factor Analysis (CFA), the fit indices were deemed acceptable (χ^2/df = 2.006, CFI = 0.96, GFI = 0.95, AGFI = 0.89, TLI = 0.93, RMSEA = 0.08). The reliability was confirmed with an alpha coefficient of 0.81 and an Intraclass Correlation Coefficient (ICC) of 0.98. Conclusion: The Persian version of the OAB-V8 questionnaire demonstrated good validity and reliability, indicating its suitability for use in Persian-speaking countries.

Translation, transcultural adaptation, and convergent validity of the Arabic version of the Mukbang addiction scale.

INTRODUCTION: The present study evaluated the psychometric properties of the Arabic translation of the Mukbang Addiction Scale (MAS) among Arabic-speaking adults from the general population. Specifically, it aimed to assess the factorial structure through a confirmatory factor analysis, determine the composite reliability through Cronbach alpha and McDonald's omega scores, assess gender invariance, and evaluate the convergent validity by examining its correlation to eating addiction and psychological distress. METHODS: A total of 370 individuals with a mean age of 21.94 ± 2.29 years participated in this study, which was conducted using an online platform. The participants were surveyed on demographic information, mukbang addiction, food addiction, and psychological distress. Translation was conducted using the forward and backward technique. RESULTS: The findings demonstrated excellent internal consistency of the Arabic MAS (McDonald's omega coefficient = 0.93). Confirmatory factor analyses validated the one-factor structure of the scale, while establishing measurement invariance across sex at the configural, metric, and scalar levels. No sex differences were observed in the Mukbang addiction levels. Lastly, the MAS scores were significantly and positively correlated with food addiction and psychological distress, supporting their convergent validity. CONCLUSION: The current research provides evidence supporting the reliability and validity of the Arabic version of the MAS as a self-report method for assessing addictive Mukbang watching. While further validations are needed to corroborate the present findings, this measure can be effectively utilized across different fields, including schools, mental health centers, and researchers aiming to understand this global phenomenon. Mukbang refers to individuals or hosts consuming large quantities of food while interacting with their audiences through recorded video or a live stream. The Mukbang phenomenon has gained substantial popularity among young individuals over the past years, rising concerns about its potential impact on their eating habits and health, especially when overconsumed. Overconsumption of mukbang content, or Mukbang addiction, aligns with the core features of addiction, including compulsive engagement, tolerance, and withdrawal symptoms, making it comparable to other addictive behaviors. Mukbang addiction can lead to detrimental effects on mental and physical health, including neglect of balanced nutrition, disordered eating habits, obesity, feelings of guilt, shame, poor self-esteem, distorted self-images, body dissatisfaction, heightened anxiety or depression, and social isolation. Given these significant impacts, valid and reliable tools are crucial to enable an accurate assessment of Mukbang addiction. This study proposes to translate, adapt and examine the psychometric properties of the Mukbang Addiction Scale (MAS) in a sample of Arabic-speaking individuals from the general population. Findings showed that the six MAS items loaded on a single factor with strong internal consistency and good convergent validity, preliminarily indicating its potential validity and reliability for assessing addictive mukbang-watching among Arabic-speaking individuals.

Evaluation of cross-cultural adaptation and validation of the Persian version of the critical thinking disposition scale: methodological study.

INTRODUCTION: Assessing critical thinking disposition is crucial in nursing education to foster analytical skills essential for effective healthcare practice. This study aimed to evaluate the cross-cultural adaptation and validation of the Persian version of the Critical Thinking Disposition Scale among Iranian nursing students. METHOD: A total of 390 nursing students (mean age = 21.74 (2.1) years; 64% female) participated in the study. Face and content validity were established through feedback from nursing students and expert specialists, respectively. Construct validity was assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The EFA was used to explore the number of factors and the items that were loading on them. The CFA was used to confirmed the fidnings of the EFA on the same sample. Convergent and discriminant validity were examined, along with reliability through internal consistency and test-retest reliability. RESULTS: EFA revealed a two-factor structure, comprising "Critical Openness" and "Reflective Skepticism," explaining 55% of the total variance. CFA confirmed the model's fit (χ² = 117.37, df = 43, χ²/df = 2.73, p < 0.001; RMSEA = 0.067; CFI = 0.95; TLI = 0.93, SRMR = 0.041). Convergent and discriminant validity were supported, with significant factor loadings (p < 0.001) ranging from 0.61 to 0.77. The CTDS exhibited strong internal consistency (α = 0.87) and excellent test-retest reliability (ICC = 0.96). CONCLUSION: The validation of the CTDS in Persian language settings provides a reliable tool for assessing critical thinking disposition among Iranian nursing students. The two-factor structure aligns with previous research, reflecting students' propensity towards critical openness and reflective skepticism. The study's findings underscore the importance of nurturing critical thinking skills in nursing education.

Psychometric validation of the Chinese Version of the stimulant relapse risk scale (SRRS) in patients with methamphetamine use disorder.

BACKGROUND: Evaluating the risk of relapse is a pivotal step in the treatment of patients with methamphetamine use disorder (MUD). The 30-item Stimulant Relapse Risk Scale (SRRS) was originally developed in Japan to meet the demand. This study examined the reliability, validity, and factor structure of the Chinese version of the SRRS for patients with MUD. METHODS: 247 patients with MUD self-rated the Chinese version of the SRRS. Cronbach's alpha coefficients and inter-item correlation analysis were used to assess the internal consistency reliability. Construct validity was determined through confirmatory factor analysis (CFA), and concurrent validity was examined using the visual analogue scale (VAS) for drug craving and the severity of dependence scale (SDS). We followed the participants for 1 year and assessed the predictive validity based on the correlation of the scores of the Chinese version of the SRRS with the relapse rate within 3, 6, and 12 months of follow-up. RESULTS: CFA revealed satisfactory model fit estimates for the 22-item Chinese version of the SRRS that consisted of four subscales. The four-factored 22-item Chinese version of the SRRS had adequate internal consistency with Cronbach's alphas ranging from 0.76 to 0.92. The 22-item Chinese version of the SRRS scores were significantly correlated with the VAS and SDS scores as well as the relapse rate within 3, 6, and 12 months, indicating good concurrent and predictive validity of this scale. The receiver operating characteristic curve revealed a cutoff score of 40 could discriminate between participants with (SDS score ≥ 4) and without (SDS score < 4) methamphetamine dependence (area under the curve = 0.71, p < 0.01). CONCLUSIONS: The 22-item Chinese version of the SRRS that consists of four subscales is a valid and reliable instrument to assess the relapse risk in patients with MUD.

Development of a tool measuring various aspects of social detachment: The social detachment questionnaire for older population.

BACKGROUND: Social detachment includes the subjective aspect "loneliness" and the objective aspect "social isolation," but tools to assess both dimensions are limited. This study aims to develop a questionnaire, the Social Detachment Questionnaire for Older Population (SDQO), that considers multiple dimensions of social detachment simultaneously. METHODS: The study collected 600 valid samples from individuals aged 55 and above to examine the psychometric properties of the developed SDQO. Item analysis was conducted to assess the performance of each item, and exploratory factor analysis (EFA) was employed to analyze its initial structure and eliminate less ideal items. Subsequently, confirmatory factor analysis (CFA) was used to examine the model fit of the suggested structure by EFA, using different subsamples. Internal consistency, concurrent validity, and other analyses were also performed. RESULTS: The original 27-item SDQO was reduced to 17 items after removing 4 questions in item analysis and 6 questions in EFA. The Cronbach's alpha for the 17-item version of SDQO was 0.80. Both EFA and CFA supported its 6-factor structure, with factors identified as community activities, loneliness, personal resources, leisure activities, friendship, and family resources. SDQO also demonstrated expected performance in concurrent validity. CONCLUSION: The 17-item version of SDQO exhibited good reliability and validity, measuring various aspects of social detachment behavior, feelings, and resources. It holds value for future research applications.

Psychometric Properties of the Persian Version of the Intensive Care Experience Questionnaire (ICE-Q).

Background and Purpose: It is important to assess the experience of patients who have been admitted to an intensive care unit to provide the best treatment and nursing care possible. Therefore, a valid and reliable tool is necessary for measurement. This study aimed to determine the psychometric properties of the Persian version of the Intensive Care Experience Questionnaire (ICEQ) for open-heart surgery patients. Methods: The study was conducted in four steps: translation, face and content validity, confirmatory factor analysis, and reliability assessment. The adapted questionnaire was administered to 200 Iranian cardiac surgery patients who had received treatment in an intensive care unit within the past month. Results: In the final Persian version of ICEQ, there are 4 factors and 21 items. Following the translation and cultural adaptation process, the content validity was evaluated. Three items had content validity ratio < 0.6, so they were deleted. Scale-level content validity index/Average was 0.81 and more than 0.7 for each item on the scale. This scale was validated through confirmatory factor analysis using fit indicators (comparative fit index, normalized fit index, root mean square error of approximation, and chi-square). There was Cronbach's alpha of 0.71-0.85, and intraclass correlation coefficients were 0.82-0.93 for subscales. Conclusions: The Persian version of ICEQ showed appropriate psychometric properties. This scale may be useful to inform the development of effective interventions to improve subsequent outcomes for Iranian open-heart surgery patients.

Psychometric Properties of the Teleprimary Care Oral Health Clinical Information System (TPC-OHCIS) Questionnaire Using the Rasch Model.

Background The Tele Primary Care Oral Health Clinical Information System (TPC-OHCIS) was implemented in Malaysia to digitalize health care and reduce numerous ground-level manual tasks. This study measures the psychometric properties of the TPC-OHCIS questionnaire among healthcare workers (HCWs) at primary healthcare clinics (PHC). Method A pilot study was conducted at PHC, which implemented the TPC-OHCIS application for service delivery. The questionnaire contained 65 items with four response categories, grouped into four scales: technology, organization, external support, and human resource. The questionnaire items were analyzed using the Rasch model in Winsteps 3.72.3. Results There were 319 respondents who participated (98.8%). The Cronbach alpha was 0.93. The construct validity was determined by a positive point measure correlation (PMC) value, with an infit and outfit mean square (MNSQ) range of 0.4-1.5 and a Z-standardized (ZSTD) range of -2.0 to 2.0. The person and item reliability were 0.93 and 0.97, respectively, indicating excellent reliability. The questionnaire was unidimensional, where the raw variance explained by measures was >40%. Conclusion The questionnaire was deemed fit for an actual survey after 18 items had been deleted. It has good psychometric properties and is practically applicable for evaluating HCWs on the TPC-OHCIS application implementation process monitoring using the local Malay language. High reliability and unidimensionality were achieved, supporting its use in digital healthcare. With this validated questionnaire, it will enhance digital healthcare implementation and streamline manual tasks.

Longitudinal measurement invariance and psychometric properties of the Patient Health Questionnaire-Four in China.

BACKGROUND: Depression and anxiety symptoms among medical students are often a concern. The Patient Health Questionnaire-Four (PHQ-4), an important tool for depression and anxiety screening, is commonly used and easy to administer. This study aimed to assess and update the longitudinal measurement invariance and psychometric properties of the simplified Chinese version. METHODS: A three-wave longitudinal survey was conducted among healthcare students using the PHQ-4. Structural validity was based on one-factor, two-factor, and second-order factor models, construct validity was based on the Self-Rated Health Questionnaire (SRHQ), Sleep Quality Questionnaire (SQQ), and Rosenberg Self-Esteem Scale (RSES), and longitudinal measurement invariance (LMI), internal consistency, and test-retest reliability were based on structural consistency across three time points. RESULTS: The results of the confirmatory factor analysis indicated that two-factor model was the best fit, and LMI was supported at three time points. Inter-factor, factor-total, and construct validity correlations of the PHQ-4 were acceptable. Additionally, Cronbach's alpha, McDonald's omega, and the intraclass correlation coefficient demonstrated acceptable/moderate to excellent reliability of the PHQ-4. CONCLUSIONS: This study adds new longitudinal evidence that the Chinese version of the PHQ-4 has promising LMI and psychometric properties. Such data lends confidence to the routine and the expanded use of the PHQ-4 for routine screening of depression and anxiety in Chinese healthcare students.

Pandemic Paranoia Scale for Adolescents (PPS-A): An Initial Psychometric Evaluation and Prevalence Study of Adolescents in the United States and United Kingdom.

Paranoid thoughts have been reported in 20-30% of adolescents, and preliminary research has shown that paranoia and psychotic-like experiences have increased during the COVID-19 pandemic. However, previous research has typically used general measures to assess paranoia, rather than those specific to COVID-19, which may overlook particular facets of paranoia related to the pandemic and result in an under-reporting of paranoia prevalence rates during this time. Therefore, this study aimed to examine the psychometric properties of the Pandemic Paranoia Scale for Adolescents (PPS-A), which was adapted from the original scale to be appropriate for younger respondents, and to assess the prevalence of pandemic paranoia among adolescents. Adolescents (N = 462) recruited on Qualtrics from the United States (US) and United Kingdom (UK) completed an online survey consisting of the PPS-A and measures of general paranoia and negative affect. A subset of adolescent's parents (N = 146) also completed an online survey providing dyadic data. Findings showed that the PPS-A shared the same three factor structure as the adult PPS (i.e., persecutory threat, paranoid conspiracy, and interpersonal mistrust) and across participant nationality, race, gender, and mental health diagnosis. It also demonstrated strong psychometric properties. The overall prevalence rate of pandemic-related paranoia among adolescents was 21% and prevalence rates were higher among US participants than UK participants. This study provides the most comprehensive psychometric evaluation of a pandemic paranoia scale designed for adolescents and highlights the continued prevalence of pandemic paranoia in this age-group nearly two years after COVID-19 began.

Psychometric properties of the Fraboni scale of ageism (FSA) applied to long-term caregivers in nursing homes.

BACKGROUND: The aging society has resulted in enormous demand for long-term care services. However, ageism is a common phenomenon in long-term care facilities, which not only hinders the quality of care for the recipients but also negatively influences caregivers' well-being. In this paper, we first applied the Fraboni Scale of Ageism (FSA) to evaluate its reliability and construct validity among Chinese long-term caregivers in nursing homes. This study could contribute to assessing the prevalence of ageism in Chinese long-term caregivers, prompting facilities and the government to recognize the issue of ageism and explore necessary interventions to reduce ageism in long-term caregivers. METHODS: This is a cross-sectional study. We recruited 392 long-term caregivers using a convenience sampling strategy in nursing homes from two cities in Chinese central and northern regions. Parameters included the demographic characteristics, Cronbach's alpha coefficients, and intraclass correlation coefficient. The construct validity was conducted by exploratory factor analysis and confirmatory factor analysis. RESULTS: The Cronbach's alpha of FSA (Chinese version) was 0.856 and ICC was 0.871. The factor analysis identified 3 principal factors, explaining 43.95% of the total variance. The 3-factor model was confirmed to fit by confirmatory factor analysis. CONCLUSIONS: The findings confirm that the FSA is easy to use and has good psychometric properties. This study will contribute to improving the condition of ageism, thereby improving the quality of care for the elderly and retention of professional talents in the LTC system.

Psychometric properties of the modified Drug Abuse Screening Test Sinhala version (DAST-SL): evaluation of reliability and validity in Sri Lanka.

BACKGROUND: Psychoactive drug use is an important public health issue in Sri Lanka as it causes substantial health, social and economic burden to the country. Screening for substance use disorders in people who use drugs is vital in preventive health care, as it can help to identify problematic use early. Screening can aid in referring those in need, for the most appropriate treatment and care. Thus, preventing them from developing severe substance use disorders with complications. The Drug Abuse Screening Test (DAST-10) is an evidence-based tool widely used to assess the severity of psychoactive drug use. This study aimed to culturally adapt and evaluate the validity and reliability of the Drug Abuse Screening Test (DAST-10) in Sri Lanka. METHODS: The DAST-10 was culturally adapted, and the nine-item Sinhala version (DAST-SL) was validated using exploratory and confirmatory factor analysis. The validation study was conducted in the Kandy district among people who use drugs, recruited using respondent-driven sampling. Criterion validity of the questionnaire was assessed by taking the diagnosis by a psychiatrist as the gold standard. Cut-off values for the modified questionnaire were developed by constructing Receiver Operating Characteristic (ROC) curves. The reliability of the DAST-SL was assessed by measuring its internal consistency and test re-test reliability. RESULTS: The validated DAST-SL demonstrated a one-factor model. A cut-off value of ≥ 2 demonstrated the presence of substance use disorder and had a sensitivity of 98.7%, specificity of 91.7%, a positive predictive value of 98.8% and a negative predictive value of 91.3%. The area under the curve of the ROC curve was 0.98. A cut-off score of ≤ 1 was considered a low level of problems associated with drug use. The DAST-SL score of 2-3 demonstrated a moderate level of problem severity, a score of 4-6 demonstrated a substantial level of problems, and a score of ≥ 7 demonstrated a severe level of drug-related problems. The questionnaire demonstrated high reliability with an internal consistency of 0.80 determined by Kuder-Richardson Formula-20 and an inter-class correlation coefficient of 0.97 for test re-test reliability. CONCLUSION: The DAST-SL questionnaire is a valid and reliable tool to screen for drug use problem severity in people who use drugs in Sri Lanka.

Nurses' evidence-based knowledge and self-efficacy in venous access device insertion and management: Development and validation of a questionnaire.

AIM: To develop and psychometrically test an instrument to assess nurses' evidence-based knowledge and self-efficacy regarding insertion and management of venous access devices (short peripheral catheter (SPC), long peripheral catheter/midline (LPC) and PICC) and the management of totally implantable central venous catheter (Port) in adult patients. DESIGN: Multicenter cross-sectional observational study with questionnaire development and psychometric testing (validity and reliability). METHODS: An evidence-based instrument was developed including a 34-item knowledge section and an 81-item self-efficacy section including four device-specific parts. Nineteen experts evaluated content validity. A pilot study was conducted with 86 nurses. Difficulty and discrimination indices were calculated for knowledge items. Confirmatory factor analyses tested the dimensionality of the self-efficacy section according to the development model. Construct validity was tested through known group validity. Reliability was evaluated through Cronbach's alpha coefficient for unidimensional scales and omega coefficients for multidimensional scales. RESULTS: Content validity indices and results from the pilot study were excellent with all the item-content validity indices >0.78 and scale-content validity index ranging from 0.96 to 0.99. The survey was completed by 425 nurses. Difficulty and discrimination indices for knowledge items were acceptable with most items (58.8%) showing desirable difficulty and most items (58.8%) with excellent (35.3%) or good (23.5%) discrimination power, and appropriate to the content. The dimensionality of the model posited for self-efficacy was confirmed with adequate fit indices (e.g., comparative fit index range 0.984-0.996, root mean square error of approximation range 0.054-0.073). Construct validity was determined and reliability was excellent with alpha values ranging from 0.843 to 0.946 and omega coefficients ranging from 0.833 to 0.933. Therefore, a valid and reliable tool based on updated guidelines is made available to evaluate nurses' competencies for venous access insertion and management.

Validity and reliability of the Greek Migraine-Specific Quality of Life Questionnaire (MSQ Version 2.1-GR).

BACKGROUND: To assess the validity and reliability of the Migraine-Specific Quality of Life Questionnaire 2.1 (MSQv.2.1) in a group of Greek migraineurs. DESIGN-SAMPLE-METHODS: The Greek version of MSQv.2.1 (MSQv.2.1-GR), a self-report measure with 14 items in 3 domains (Role Restrictive (RR), Role Preventive (RP) and Emotional Function (EF)), was administered during a cross-sectional study to 141 Greek adult migraineurs and 135 controls without migraine or any other primary headache disorder, along with Migraine Disability Assessment Scale (MIDAS) and Short Form Health Survey (SF-12) to assess validity. MSQv.2.1-GR was re-administered in a group of participants with migraine two weeks afterwards to assess reliability. Content and construct validity was assessed using Intraclass Correlation Coefficient (ICC), Spearman rho, McDonald's omega, Cronbach's alpha. Confirmatory factor analysis (CFA) was used to test the latent structure of the MSQv.2.1-GR in migraineurs. RESULTS: A total of 276 adults participated in the study. Internal consistency of the three MSQv.2.1-GR scales RR, RP and EF yielded a range of McDonald's omega from 0.832 to 0.923 (Cronbach's alpha from 0.814 to 0.923). CFA confirmed the proposed three-factor MSQv.2.1-GR latent structure with acceptable goodness of fit indices and factor loadings. Correlations were established between MSQv2.1-GR component and MIDAS scores, showing moderate and statistically significant relationships (from - 0.519 to -0.562, all p < 0.001) for RR, RP and EF. Correlations between MSQv2.1-GR and SF-12 component scores were identified, with values from 0.1 to 0.4, indicating low to moderate associations. ICC was calculated at 0.997, indicating a high level of reliability between the measures. Notably, all MSQv2.1-GR scores (RR, RP, EF) were significantly higher in the controls compared to migraineurs (p < 0.001 for all scales). These findings suggest that MSQv2.1-GR is internally consistent, shows significant correlations with relevant measures, and is effective in discriminating controls from migraineurs. CONCLUSION: MSQv2.1-GR is a valid and reliable tool to determine the effect migraine has on the quality of life of Greek-speaking migraineurs.

Migraine is a major global health issue, ranking at the top leading causes of disability worldwide. The Migraine-Specific Quality of Life Questionnaire 2.1 (MSQ v.2.10 is an effective instrument for measuring the influence of headaches on a patient's quality of life but it is not available for the Greek migraineurs. We therefore made this study to investigate the reliability and validity of MSQv.2.1 in Greek. The Greek version (MSQv2.1-GR) was administered on a total of 142 migraineurs and 136 non-migraineurs. In addition, other instruments such as MIDAS and SF-12 were applied to determine its validity. We concluded that MSQv2.1-GR is a valid measure. There was great reliability between the items because they were measuring the same thing. It had a good correlation with other tests that evaluate migraine-related disability and quality of life. It also differentiated migraineurs from non-migraineurs in terms of quality of life. Therefore, MSQv2.1-GR proves to be an appropriate measure for examining the consequences of migraine on the health-related quality of life among Greek individuals. This tool will be helpful for clinicians in Greece as well as for research purposes such as cross-cultural studies on effects of migraine on quality of life.

Illegitimate work tasks: an investigation of psychometric properties of the Swedish version of the BITS instrument and its suitability in human versus 'non-human' service occupations.

BACKGROUND: Illegitimate tasks, i.e. working tasks that are perceived as unnecessary or unreasonable, are commonly measured by the Bern Illegitimate Tasks Scale (BITS). Despite a growing research attention paid to illegitimate tasks, the Swedish version of BITS needs yet to be properly evaluated. Moreover, previous multiorganizational studies in this field have taken for granted, without really testing it, that the instrument functions invariantly in different contexts; a prerequisite for meaningful comparisons. METHODS: Two occupational groups that differs hugely-966 human services workers (teachers and registered nurses) and 750 non-'human service' workers (construction and IT-workers) were targeted utilizing questionnaires data collected 2018 within the Swedish Longitudinal Occupational Survey of Health (SLOSH) study. Psychometric properties, i.e., reliability, dimensionality, and measurement invariance between the occupations were examined using confirmatory factor analyses and structural equation models. Also, the associations between the two dimensions of illegitimate tasks and job satisfaction and emotional exhaustion, respectively, were tested. RESULTS: Good reliability was supported and two- versus one-dimensionality showed better psychometric properties. Partial scalar measurement invariance was satisfactory supported with only 25% relaxed constraints of equal intercepts between groups. Examining the two subdimensions revealed different associations with emotional exhaustion, where the associations was more substantial for unreasonable tasks. Nevertheless, the findings point to potential improvements for future investigation. CONCLUSIONS: This study shows that the Swedish version of BITS is working satisfactory and allows for meaningful comparisons of occupational groups. Furthermore, construct validity of the two dimensions was corroborated.

Protocol for a systematic review evaluating psychometric properties and gender-related measurement (non)invariance of self-report assessment tools for autism in adults.

BACKGROUND: Given the recent evidence on gender differences in the presentation of autism, there is an increasing concern that current tools for autism do not adequately capture traits more often found in women. If tools for autism measure autistic traits differently based on gender alone, their validity may be compromised as they may not be measuring the same construct across genders. Measurement invariance investigations of autism measures can help assess the validity of autism constructs for different genders. The aim of this systematic review is to identify and critically appraise the psychometric properties of all self-report tools for autism in adults that meet two criteria: (a) they have been published since or included in the NICE (2014) recommendations, and (b) they have undergone gender-related measurement invariance investigations as part of their validation process. METHODS: A search of electronic databases will be conducted from 2014 until the present using MEDLINE, Embase, and PsycINFO using predefined search terms to identify eligible studies. The search for grey literature will include sources such as OpenGrey, APA PsycEXTRA, and Scopus. Two reviewers will independently screen titles, abstracts, and full texts for eligibility. The references of included studies will be searched for additional records. The methodological quality of the studies will be evaluated using the COSMIN Risk of Bias checklist, while psychometric quality of findings will be assessed based on criteria for good measurement properties and ConPsy checklist. The quality of the total body of evidence will be appraised using the approach outlined in the modified GRADE guidelines. DISCUSSION: This systematic review will be among the first to assess the psychometric properties and gender-related measurement invariance of self-reported measures for autism in adults that were published since (or included in) NICE (2014) guidelines. The review will provide recommendations for the most suitable tool to assess for autism without gender bias. If no such measure is found, it will identify existing tools with promising psychometric properties that require further testing, or suggest developing a new measure. SYSTEMATIC REVIEW REGISTRATION: The protocol has been registered at the International Prospective Register of Systematic Reviews (PROSPERO). The registration number is CRD42023429350.

Development and psychometric properties of the Balance in Daily Life (BDL) scale in a population of frail older people.

BACKGROUND: Balance disorders in older people cause falls, which can have serious functional and economic consequences. No existing scale relates fall risk to daily life situations. This study describes the development, psychometric properties and construct validity of the Balance in Daily Life (BDL) scale, comprising seven routine tasks including answering a phone, carrying a heavy bag, and sitting down and getting up from a chair. METHODS: Frail patients aged 65 years or more were prospectively recruited from the geriatric rehabilitation department of a French university hospital. Inclusion criteria included autonomous walking over 20 m and modified Short Emergency Geriatric Assessment score 8-11. Patients with motor skills disorders and comprehension or major memory difficulties were excluded. Patients were assessed on Day 3 and Day 30 with the Balance in Daily Life scale, Timed Up and Go, one-leg stance time, sternal nudge and walking-while-talking tests. The scale was assessed for acceptability, quality, unidimensionality, internal consistency, reliability, temporal stability, responsiveness and construct validity. RESULTS: 140 patients (83 ± 6 years) were recruited, of whom 139 were assessed at Day 0 and 133 at Day 30. Acceptability was satisfactory (134/139 patients completed the test), quality assessment showed a slight floor effect (6 % of patients with minimal score) and evaluation of item redundancy found no strong correlation (Spearman <0.7). Unidimensionality was verified (Loevinger H coefficient > 0.5 for all items except item 6 = 0.4728). Internal consistency was good (Cronbach alpha = 0.86). Reliability and temporal stability were excellent (ICC = 0.97 and ICC = 0.92). Responsiveness was verified by significant score change p < 0.0001 between Day 0 and Day 30 (decreased by 1 [0; 2] point), in line with other score changes. Construct validity revealed that the Balance in Daily Life scale was convergent with results of the timed up-and-go and one-leg stance time (p < 0.0001 for both) and tended to be higher for participants who had not fallen in the previous 6 months (p = 0.0528). The new questionnaire was divergent to sternal nudge tests (p = 0.0002) and not related to the walking-while-talking test (p = 0.5969). CONCLUSION: The Balance in Daily Life scale has good psychometric properties for this population. Its simplicity and innovative nature mean that it can be applied in institutions while being easily modifiable to domestic settings. Study registration on clinicaltrials.gov: NCT0334382.
