Psychometric properties of the Spanish version of the Chalder Fatigue Scale in clinical and general populations / Propiedades psicométricas de la versión española de la Escala de Fatiga de Chalder en población clínica y general

Objetivo: La Escala de Fatiga de Chalder (CFS) es una escala breve para evaluar fatiga que se utiliza en España, pero que no ha sido validada en su población. El objetivo del estudio fue adaptar y evaluar las propiedades psicométricas de la versión española de la CFS (Sp-CFS). Método: La muestra la conformaron 3,671 participantes (3.190 de la población general y 481 pacientes), con edades entre 18 y 86 años (M = 28.43; DT = 12.71), siendo el 67.6% mujeres. Las propiedades psicométricas de la escala se probaron en un diseño transversal utilizando validación cruzada (análisis factorial exploratorio y confirmatorio) y estimación de la invarianza (sexo y condición clínica). Resultados: Un modelo de cuatro factores (baja energía, problemas de sueño, problemas de concentración y disfunción cognitiva subjetiva) en lugar de un modelo original de dos factores (fatiga física y mental) proporcionó mejores índices de bondad de ajuste a los datos. La consistencia interna y la estabilidad de la escala fueron excelentes. Su validez convergente se apoyó en su asociación significativa con la ansiedad, la depresión, el estrés y los síntomas positivos y negativos del espectro de la psicosis. El instrumento no mostró diferencias significativas entre sexos ni condiciones clínicas, y discriminó entre la población general y los pacientes, obteniendo estos últimos puntajes significativamente mayores. Conclusiones: Sp-CFS es una escala fiable y válida para medir la fatiga en población general y clínica española.(AU)

Objective:The Chalder Fatigue Scale (CFS) is a brief self-report screening scale for fatigue that is used in Spain but has not been validated for the Spanish population. The aim of this study was to adapt and evalu-ate the psychometric properties of the Spanish version of the CFS (Sp-CFS). Method:The sample consisted of 3,671 participants (3,190 from the general population and 481 patients), aged 18 to 86 years (M=28.43; DT=12.71), 67.6% of whom were women. Psychometric properties of the scale were tested in a cross-sectional design using cross-validation (explora-tory and confirmatory factor analysis) and estimation of invariance (sex and clinical condition). Results:A four-factor model (low energy, sleep problems, concentration problems and subjective cognitive dysfunction) rather than an original two-factor model (physical and mental fatigue) pro-vided better indices of goodness of fit to the data. The internal consistencyand stability of the scale were excellent. Its convergent validity was sup-ported by its significant association with anxiety, depression, stress, and the positive and negative symptoms of the psychosis spectrum. The instru-ment did not show significant differences between sexes or clinical condi-tions, and it discriminated between the general population and the patients, with the latter obtaining significantly greater scores. Conclusions: Sp-CFS is a reliable and valid scale for measuring a transdiagnostic construct such as fatigue in Spanish general and clinical populations.(AU)

Teacher Emotion Inventory: validación en una muestra de profesorado español / Teacher Emotion Inventory: validation in a sample of Spanish teachers

Antecedentes: La escala Teacher Emotion Inventory (TEI) es un instrumento que evalúa emociones discretas experimentadas por el profesorado en el proceso de enseñanza-aprendizaje. El objetivo de este estudio es examinar las propiedades psicométricas de la versión breve española de la escala Teacher Emotion Inventory (TEI-BSV) en una muestra de 567 profesores (65.5% son mujeres), con edades comprendidas entre 25 y 65 años (M = 46.04; DT = 9.09). Método: Tras su adaptación mediante traducción inversa, el profesorado completó una batería que incluía el TEI-BSV, un cuestionario de inteligencia emocional, dos escalas de bienestar subjetivo, una escala sobre burnout y una escala sobre engagement. Resultados: Los resultados mostraron una consistencia interna adecuada de las subescalas del TEI-BSV. Los análisis factoriales (exploratorio y confirmatorio) proporcionaron pruebas de que el TEI-BSV tiene una estructura de cuatro factores con un buen ajuste, frente a la estructura de cinco factores original. Se han hallado evidencias de validez convergente, así como de validez criterial e incremental del TEI-BSV. Conclusiones: el TEI-BSV podría ser una herramienta útil para la evaluación ecológica de las emociones discretas del profesorado en su contexto laboral.(AU)

Background: The Teacher Emotion Inventory (TEI) scale is an instrument that evaluates discrete emotions experienced by teachers in the teaching-learning process. The aim of this study was to examine the psychometric properties of the brief Spanish version of the Teacher Emotion Inventory scale (TEI-BSV) using a sample of 567 teachers (65.5% women), aged between 25 and 65 years (M= 46.04; SD= 9.09). Methods: After adaptation through back-translation, the teachers com-pleted a battery of tests included in the TEI-BSV: an emotional intelli-gence questionnaire, two subjective well-being scales, a burnout scale and a scale on engagement. Results: The data revealed adequate internal consistency of the TEI-BSV subscales, and exploratory and confirma-tory factor analyses provided evidence that the TEI-BSV has a four-factor structure with good adjustment, as opposed to the original five-factor structure proposed. There was evidence of convergent validity of the TEI-BSV, as well as criterion and incremental validity. Conclusions: The TEI-BSV could be a useful instrument for the ecological assess-ment of teachers' discrete emotions in the context of their workplace.(AU)

Development and psychometric evaluation of a questionnaire for the assessment of depression in primary care: a cross-sectional study.

OBJECTIVES: To develop a new questionnaire for the diagnostic assessment of depression adapted to the primary care setting by combining psychiatric criteria and heuristics of general practitioners (GPs). Psychometric evaluation of the new questionnaire and first validity evidence. DESIGN: The questionnaire was developed using cognitive interviews with think-aloud technique. Factorial validity was then examined in a cross-sectional study. SETTING: Primary care. Five general practices in Bavaria, Germany. PARTICIPANTS: 15 GPs, 4 psychiatrists/psychotherapists and 13 patients participated in cognitive expert interviews. A primary care sample of N=277 consecutive patients participated in the cross-sectional study. METHODS: After consultation with experts and literature research, the questionnaire contained a self-rating part for patients and an external part for GPs. Items were then iteratively optimised using cognitive interviews. Factorial validity was examined. To estimate internal consistency, Cronbach's α was calculated. Validity was assessed by correlating the new questionnaire and the Patient Health Questionnaire-9 (PHQ-9). RESULTS: The preliminary version of the two-part 'Questionnaire for the assessment of DEpression SYmptoms in Primary Care' (DESY-PC) comprised 52 items for patients (DESY-PAT-1: questions about patient's environment; DESY-PAT-2: questions about depression-specific symptoms) and 21 items for GPs (DESY-GP). The analysis of the DESY-PAT-1 revealed a one-factor solution ('environmental factors') with Cronbach's α of 0.55. The items of the DESY-PAT-2 were assigned to three factors, 'depressive cognitions', 'suicidality' and 'symptoms of fatigue', with Cronbach's α of 0.86, 0.79 and 0.85, respectively. Factorial analysis revealed two factors for the DESY-GP: 'depression symptoms' and 'medical history/external factors'. Cronbach's α was 0.90 and 0.59, respectively. After factorial analysis, the DESY-PAT was reduced to 28 items, and the DESY-GP was reduced to 15 items. Correlations of the DESY-PC with the PHQ-9 were high and significant, indicating convergent validity. CONCLUSIONS: The new questionnaire represents an innovative extension of depression questionnaires and could be particularly suitable for general practices.

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.

Capturing patient-reported sleep disturbance in atopic dermatitis clinical trials.

BACKGROUND: Patient-focused approaches to capturing day-to-day variability in sleep disturbance are needed to properly evaluate the sleep benefits of new treatments. Such approaches rely on patient-reported outcome (PRO) measures validated in the target patient population. METHODS: Using atopic dermatitis (AD) as an example of a disease in which sleep is commonly disturbed, we developed a strategy for measuring sleep disturbance in AD trials. In developing this strategy, we conducted a targeted literature review and held concept elicitation interviews with adolescents and adults with AD. We subsequently identified potentially suitable PRO measures and cognitively debriefed them. Finally, we evaluated their psychometric properties using data from phase 2b (NCT03100344) and phase 3 (NCT03985943 and NCT03989349) clinical trials. RESULTS: The literature review confirmed that sleep disturbance is a key impact of AD but failed to identify validated PRO measures for assessing fluctuations in sleep disturbance. Subsequent concept elicitation interviews confirmed the multidimensional nature of sleep disturbance in AD and supported use of a single-item measure to assess overall sleep disturbance severity, complemented by a diary to capture individual components of sleep disturbance. The single-item sleep disturbance numerical rating scale (SD NRS) and multi-item Subject Sleep Diary (SSD)-an AD-adapted version of the Consensus Sleep Diary-were identified as potentially suitable PRO measures. Cognitive debriefing of the SD NRS and SSD demonstrated their content validity and their understandability to patients. Psychometric analyses based on AD trial data showed that the SD NRS is a well-defined, reliable, and fit-for-purpose measure of sleep disturbance in adults with AD. Furthermore, the SD NRS correlated with many SSD sleep parameters, suggesting that most concepts from the SSD can be covered using the SD NRS. CONCLUSIONS: Using these findings, we developed an approach for measuring sleep disturbance in AD trials. Subject to further research, the same approach could also be applied to future trials of other skin diseases where itch causes sleep disturbance.

Development and validation of a mental hyperactivity questionnaire for the evaluation of chronic stress in higher education.

BACKGROUND: Examination and understanding of neural hyperactivity are some of the greatest scientific challenges faced in the present day. For this reason, the present study aimed to examine this phenomenon in the context of higher education. METHOD: Likewise, this work will enable an instrument to be created to appropriately and reliably estimate neural hyperactivity associated with chronic stress in university students undertaking a Physiotherapy degree. RESULTS: Analysis of content validity was carried out according to agreement and consensus between nineteen experts with Education Science or Psychology degrees, via the Delphi method. On the other hand, face validity was established by administering the questionnaire to a sample of 194 university students aged between 18 and 45 years (M = 30.48%; SD = 13.152). CONCLUSION: The final self-report measure, denominated mental hyperactivity, was composed of 10 items which showed adequate fit with regards to face and content validity (α = 0.775). Confirmatory factor analysis confirmed that the questionnaire was unidimensional.

Validation of the patient reported experiences and outcomes of safety in primary care compact Form Brazil.

OBJECTIVE: To analyze the psychometric properties of the cross-culturally adapted version of the Patient Reported Experiences and Outcomes of Safety in Primary Care (PREOS-PC) Compact Form Brazil. METHODS: A methodological study was conducted with 281 adult Primary Health Care users. Data collection took place online. Confirmatory Factor Analysis (CFA) was used to evaluate the psychometric properties of the PREOS-PC after the process of cross-cultural adaptation to the Brazilian context. Internal consistency was evaluated through Cronbach's alpha coefficient (α) and McDonald's omega coefficient (ω). RESULTS: The sample consisted of 73.3% women. The mean age was 36.1 years (SD = 12.2). Of the 23 items of the PREOS-PC that were eligible for CFA, a model with four correlated domains and 16 items presented satisfactory fit indexes. The domains were Practice Activation (PrA) (four items), Patient Activation (PaA) (two items), Experiences of patient safety events (EPaS) (five items) and Outcomes of patient safety (OPaS) (six items). One domain (GPeS) presented one question with a 0 to 10 response scale and two open questions, which cannot be inserted in the CPA due to the nature of the items, but can be included in the application of the scale, being evaluated individually. In this factorial model, five items (EPaS2, EPaS3, EPaS4, EPaS5, EPaS6 and EPaS8) presented factor loadings ≤ 0.30. The α and ω values demonstrated good internal consistency for all domains of the PREOS-PC. CONCLUSIONS: The Brazilian version of the PREOS-PC Compact Form Brazil composed of four domains (PrA, PA, EPaS and OPaS) and 16 items presented evidence of validation of its psychometric properties and can be used to evaluate the experiences and results of patient safety in Primary Health Care in the Brazilian context.

Validating the Ontario Child Health Study Emotional Behavioural Scales-Brief Version (OCHS-EBS-B) in children with chronic physical illness.

BACKGROUND: A substantial proportion of children have a physical illness; these children commonly experience physical-mental comorbidity. To assess child mental health, brief scales that can be used in clinical and research settings are needed. This study assessed the validity and reliability of parent-reported Ontario Child Health Study Emotional Behavioural Scale-Brief Version (OCHS-EBS-B) scores. METHODS: Data come from a longitudinal study of children aged 2-16 years with a physical illness recruited from outpatient clinics at a pediatric hospital. Confirmatory factor analysis and McDonald's coefficient assessed the factor structure and internal consistency reliability of the OCHS-EBS-B, respectively. Point biserial correlations assessed agreement between the OCHS-EBS-B and Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID), a structured diagnostic interview. The Wilcoxon rank sum test compared OCHS-EBS-B scores between children with versus without physical-mental comorbidity (known-group validity). RESULTS: The three-factor structure of the OCHS-EBS-B was replicated in this sample of children with physical illness (χ2 = 196.23(272), p < 0.001; CFI = 0.98; TLI = 0.98; SRMR = 0.06; RMSEA [90% CI] = 0.034 [0.027, 0.044]). It had excellent internal consistency reliability (ω = 0.86-0.92) and was moderately correlated with the MINI-KID (baseline: rpb = 0.43-0.51; 6 months: rpb = 0.55-0.65). OCHS-EBS-B scores were significantly higher among children with versus without physical-mental comorbidity. CONCLUSIONS: Findings confirm psychometric evidence that the OCHS-EBS-B is a valid and reliable measure of mental health in children with chronic physical illness. Its brevity and robust psychometric properties make the OCHS-EBS-B a strong candidate for routine use in integrated pediatric physical and mental health services.

Re-examining the factor structure of the Insomnia Severity Index (ISI) and defining the meaningful within-individual change (MWIC) for subjects with insomnia disorder in two phase III clinical trials of the efficacy of lemborexant.

BACKGROUND: The Insomnia Severity Index (ISI) is a widely used measure of insomnia severity. Various ISI research findings suggest different factor solutions and meaningful within-individual change (MWIC) to detect treatment response in patients with insomnia. This study examined an ISI factor solution and psychometric indices to define MWIC in a robust patient sample from clinical trial settings. METHODS: We endeavored to improve upon previous validation of ISI by examining structural components of confirmatory factor analysis (CFA) models using two large, placebo-controlled clinical trials of lemborexant for insomnia. Using the best-fitting two-factor solution, we evaluated anchor-based, distribution-based and receiver operating characteristic (ROC) curve methods to derive an estimate of the MWIC. RESULTS: The model structure for the 7-item scale proposed in other research did not fit the observed data from our two lemborexant clinical trials (N = 1956) as well as a two-factor solution based on 6 items did. Using triangulation of anchor-based, distribution-based, and ROC methods, we determined that a 5-point reduction using 6 items best represented a clinically meaningful improvement in individuals with insomnia in our patient sample. CONCLUSIONS: A 6-item two-factor scale had better psychometric properties than the 7-item scale in this patient sample. On the 6-item scale, a reduction of 5 points in the ISI total score represented the MWIC. Generalizability of the proposed MWIC may be limited to patient populations with similar demographic and clinical characteristics.

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.

Psychometric properties of the arabic translation of the Physical Appearance Comparison Scale-Revised (PACS-R) in adults.

BACKGROUND: Physical comparison may be a factor in body dissatisfaction and related issues, like eating disorders and depression. The Physical Appearance Comparison Scale-Revised (PACS-R) is a scale developed to assess the frequency of physical comparison. Because there is no validated scale for body comparison in Arabic, this study aims to address this gap by validating the PACS-R in the Arabic language. METHODS: The PACS-R was translated to Arabic following a conventional forward-backward translation procedure, and was administered to a sample of 359 Lebanese adults along with The Depression Anxiety Stress Scale, and the Rosenberg self-esteem scale (RSES) for convergent validity. The factor structure was studied by confirmatory factor analysis (CFA), and composite reliability was assessed using McDonald's omega and Cronbach's alpha. RESULTS: Results suggested a one-factor structure of the Arabic PACS-R, with good internal consistency (McDonald's ω = 0.97 / Cronbach α = 0.97). Measurement invariance was established across sex groups, with no significant difference being reported between males and females in terms of PACS-R scores (15.42 ± 10.64 vs. 13.16 ± 11.88; t(357) = 1.84; p = .066). Finally, adequate convergent validity was tested and found to be adequate, with PACS-R scores found to be correlated negatively with self-esteem and positively with psychological distress. CONCLUSION: The present findings preliminarily establish the Arabic PACS-R as an effective instrument for researchers and practitioners aiming to explore the physical comparison among Arabic-speaking populations, thus contributing to research and clinical work in the Arabic community.

The psychometric properties of the Turkish version of the Ostomy Self-Care Index and the Caregiver Contribution to Self-Care in Ostomy Patient Index.

BACKGROUND: Living with an ostomy is a chronic condition, and self-care in such cases improves patient outcomes. PURPOSE: To adapt and test the psychometric properties of the Turkish version of the Ostomy Self-Care Index (T-OSCI) and the Turkish version of the Caregiver Contribution to Self-Care in Ostomy Patient Index (T-CC-OSCI). METHODS: A psychometric study was conducted on a convenience sample of 202 adult patients with an ostomy and their 165 caregivers. Translation and back translation, face and content validity, construct validation, and reliability assessment of the T-OSCI and the T-CC-OSCI were performed. Exploratory factor analysis was used to evaluate the construct validity. Reliability was established using Cronbach α coefficients, ceiling and floor effects, and the Hotelling T2 test, Wilcoxon signed rank test, and intraclass correlation coefficient. RESULTS: Content validity values were in the range of 0.85 to 1 for both the T-OSCI and the T-CC-OSCI. Exploratory factor analysis demonstrated generally acceptable factor loadings. The overall index revealed a high level of internal consistency (T-OSCI = 0.968, T-CC-OSCI = 0.862). No statistically significant difference was found between test-retest measurements. There was no indication of either ceiling or floor effects, or response bias. CONCLUSION: The T-OSCI and the T-CC-OSCI are valid and reliable indexes to measure the self-care of patients with an ostomy and their caregivers. These indexes may allow health care professionals to evaluate self-care in research and clinical settings, identify educational needs, and collaborate in developing and supporting appropriate self-care initiatives for patients with an ostomy and their caregivers.

The public's perception of the nursing profession: Validity and reliability of the Chinese version of the nursing image scale in Taiwan.

The public's perception of the nursing image deeply influences nurses' work and professional development. However, the Taiwanese public's perception of nursing remains unclear. This study aimed to determine the validity and reliability of a Chinese version of the Nursing Image Scale (NIS) in Taiwan. This was a psychometric study using a cross-sectional survey. Participants were recruited via the snowball sampling method through the online community software LINE from August 1 to 13, 2019. After data collection, the construction and validation of the NIS to measure public opinion were assessed, including content validity, corrected item-total correlation, exploratory factor analysis (EFA), and reliability. A total of 1331 valid responses were included in the analysis. After EFA analysis, the 20 scale items were divided across the four domains of prudence and care, innovation and cooperation, efficiency and division, and professionalism and respect. The NIS (Chinese version) was valid and reliable for measuring public opinion and may be used to examine changes in public perceptions of nursing.

Measurement of basic psychological needs for physical activity participation for college students with intellectual disabilities: A validation study.

BACKGROUND: Measurement instruments to understand self-determined motivation towards physical activity among college students with intellectual disabilities are needed to develop programs to support physical and psychological health and well-being. The purpose of the current study was to validate a modified questionnaire measuring basic psychological needs towards physical activity among college students with intellectual disabilities. METHODS: A total of 108 college students with intellectual disabilities completed the modified questionnaire. Validity and reliability of the questionnaire was examined. RESULTS: Confirmatory factor analysis demonstrated a six-factor model had good model fit. Cronbach's alpha values showed acceptable reliability evidence of the instrument as a whole, although some alpha values in subdomains of the instrument were below acceptable values. CONCLUSION: The modified questionnaire was found to have acceptable validity evidence. Further studies are needed with refinement of answer options and the addition of more questions to increase reliability.

Developing an ethical attitude scale for pain management in nursing.

OBJECTIVES: The aim of this study is to develop the 'Developing an Ethical Attitude Scale for Pain Management in Nursing' to assign the ethical attitudes of nurses in pain management. METHODS: The population of the study comprised nurses (n=411) working in a university hospital in Izmir. The Ethical Attitude Scale in Nursing Pain Management was developed in five sub-dimensions: 'Care and Dignity,' 'Ethical Values,' 'Attitude,' 'Rights,' and 'Pain Management.' This scale was created by examining many research studies related to pain management in nursing in the literature and taking expert opinions. 'The Ethical Attitude Scale in Nursing Pain Management' initially consisted of 36 items. After expert opinions and validity analyses, the draft scale was reduced to 34 items, and then reliability analysis further reduced the scale to 23 items. RESULTS: In the validity and reliability study of 'The Ethical Attitude Scale in Nursing Pain Management,' the total Cronbach's alpha value of the scale was 0.86. The Cronbach's alpha value for the 'Care and Dignity' sub-dimension was 0.88; for the 'Ethical Values' sub-dimension, it was 0.83; for the 'Attitude' sub-dimension, it was 0.86; for the 'Rights' sub-dimension, it was 0.79; and for the 'Pain Management' sub-dimension, it was 0.72. CONCLUSION: According to these data, it was determined that 'The Ethical Attitude Scale in Nursing Pain Management' is a valid and reliable scale.

Development of parenting difficulties in infectious disease pandemic inventory.

BACKGROUND: The objective of this study was to develop the Parenting Difficulties in Infectious Disease Pandemic Inventory (PDIDPI) for the assessment of parenting difficulties during the coronavirus disease 2019 (COVID-19) pandemic and to examine its psychometric properties. METHODS: The 31-item PDIDPI was developed on the basis of the results of focus group interviews. An exploratory factor analysis using principal axis factoring was conducted to examine the PDIDPI factor structure. The internal consistency was assessed using Cronbach α values. The test-retest reliability was assessed using the intraclass correlation coefficient (ICC). The concurrent validity was established by examining the correlations of the PDIDPI with Fear of COVID-19 Scale and Center for Epidemiologic Studies Depression Scale (CESD) scores. RESULTS: We determined that the PDIDPI has seven factors: infection, school and learning, life change, care burden, daily living, health care, and emotion and behavior. The PDIDPI also had good internal consistency (α = 0.685-0.929) and acceptable test-retest reliability (ICC = 0.404-0.794). Regarding concurrent validity, the overall PDIDPI and its seven factors were all significantly associated with depression, determined by the CESD (r = 0.223-0.370), but not all factors were significantly associated with fear of COVID-19 (r = 0.082-0.203). CONCLUSIONS: Our findings support the psychometric properties of the PDIDPI, confirming its utility for evaluating the multifaceted challenges parents face in child management during the COVID-19 pandemic.

Validation of a German version of the caregiver strain questionnaire-short form 11 (CGSQ-SF11).

OBJECTIVE: Caring for a child, particularly one with special healthcare needs, is a demanding task that can lead to the experience of caregiver strain. This in turn has an effect on the caregiver's mental health, as well as on the child and his or her treatment. To enable the identification of afflicted parents, this study aims to provide a German version of the Caregiver Strain Questionnaire-Short Form 11 (CGSQ-SF11) and to examine its factor structure and psychometric properties. METHODS: Data from 698 caregivers were included in the analyses. Caregivers completed the CGSQ-SF11 along with measures of parenting stress (PSI-SF), stress (PSS-10), anxiety (GAD-7), depression (PHQ-8), family-related quality of life (FLQ), and social desirability (SES-17) as additional instruments for validation. A two-week follow-up questionnaire included only the CGSQ-SF11. Exploratory factor analysis followed by a confirmatory factor analysis was conducted for parents of children with and without special healthcare needs, separately. Further analyses examined the validity and reliability of the instrument. RESULTS: For parents of children with special healthcare needs, a three-factor structure (objective, internalized subjective, externalized subjective strain) with a second-order factor (caregiver strain) was supported. For parents of children without special healthcare needs, a similar three-factor structure was found, although the second-order factor was not supported. Measurement invariance between the two groups was not confirmed. Internal consistency, test-retest reliability, and validity were largely supported in both groups. CONCLUSIONS: The results indicate that the German version of the CGSQ SF-11 is a valid and reliable questionnaire for measuring caregiver strain.

Validity, reliability and factor structure of the Female Sexual Well-Being Scale in married Iranian women.

Background Promoting the quality of women's sex life is crucial for their overall well-being. The aim of this study was to translate and validate the Iranian adaptation of the Female Sexual Well-Being Scale (FSWB), and assess its cross-cultural comparability. Methods The Persian version of the FSWB was developed through forward and backward translations, followed by revision by a research team and pilot testing. A total of 400 women completed the FSWB questionnaire. Test-retest reliability was determined using the intraclass correlation coefficient, whereas Cronbach's alpha coefficient was used to assess internal consistency. Construct validity was assessed by exploratory factor analysis using principal axis factorisation with varimax rotation, followed by confirmatory factor analysis. Results Only one factor was found in the scale by factor analysis using the principal component method and varimax rotation. The Kaiser-Meyer-Olkin measure demonstrated high sampling adequacy (0.961), and Bartlett's test of sphericity confirmed the appropriateness of the correlation matrix for exploratory factor analysis (P Conclusions The Persian version of the FSWB (consisting of 17 questions) and its scoring system showed robust validity and reliability in assessing women's sexual well-being in the Iranian context.

Selecting PedsQL items to derive the PedsUtil health state classification system to measure health utilities in children.

BACKGROUND: There is a lack of preference-based health-related quality of life (HRQoL) measures that consistently value health across a full range of child age groups. The PedsQL is a generic HRQoL instrument validated for children 2-18 years, but it is not preference-based. The objective of this study was to derive the PedsUtil health state classification system from the PedsQL as a basis for a preference-based HRQoL measure for children. METHODS: A two-step process was used to select PedsQL items to include in the health state classification system: 1) exclude poorly functioning items according to Rasch analysis in each of the previously established seven dimensions of the PedsUtil health state classification system and 2) select a single item to represent each dimension based on Rasch and psychometric analyses, as well as input from child health experts and parents. All secondary analyses were conducted using data from the Longitudinal Study of Australian Children (LSAC). Analyses were stratified by age group (i.e., 2-5 years, 6-13 years, and 14-17 years) to represent the different developmental stages of children and to reflect the study design of the LSAC. Rasch analyses were also performed on five random subsamples for each age group to enhance robustness of results. RESULTS: Twelve items were excluded from the PedsUtil health state classification system after the first step of the item selection process. An additional four items were excluded in the second step, resulting in seven items that were selected to represent the seven dimensions of the PedsUtil health state classification system: Physical Functioning ("participating in sports activity or exercise"), Pain ("having hurts or aches"), Fatigue ("low energy level"), Emotional Functioning ("worrying about what will happen to them"), Social Functioning ("other kids not wanting to be their friend"), School Functioning ("keeping up with schoolwork"), and School Absence ("missing school because of not feeling well"). CONCLUSIONS: The PedsUtil health state classification system was derived from the PedsQL based on several criteria and was constructed to be applicable to children two years and older. Research is ongoing to elicit preferences for the PedsUtil health state classification system to construct the PedsUtil scoring system.

Development of a lesbian, gay, bisexual, and transgender cultural competence scale for nurses in South Korea: a methodological study.

PURPOSE: This study was conducted to develop a cultural competence scale for nurses regarding the lesbian, gay, bisexual, and transgender (LGBT) community and to test its validity and reliability. METHODS: The study adhered to the 8-step process outlined by DeVellis, with an initial set of 25 items derived through a literature review and individual interviews. Following an expert validity assessment, 24 items were validated. Subsequently, a preliminary survey was conducted among 23 nurses with experience caring for LGBT patients. Data were then collected from a final sample of 322 nurses using the 24 items. Item analysis, item-total score correlation, examination of construct and convergent validity, and reliability testing were performed. RESULTS: The item-level content validity index exceeded .80, and the explanatory power of the construct validity was 63.63%. The factor loadings varied between 0.57 and 0.80. The scale comprised five factors: cultural skills, with seven items; cultural awareness, with five items; cultural encounters, with three items; cultural pursuit, with three items; and cultural knowledge, with three items; totaling 21 items. Convergent validity demonstrated a high correlation, affirming the scale's validity. Internal consistency analysis yielded an overall reliability coefficient of 0.97, signifying very high reliability. Each item is scored from 1 to 6 (total score range, 21-126), with higher scores reflecting greater cultural competence in LGBT care. CONCLUSION: This scale facilitates the measurement of LGBT cultural competence among nurses. Therefore, its use should provide foundational data to support LGBT-focused nursing education programs.
