[Evidence of the validity of a Brazilian version of the Fear of COVID-19 Scale]. / Evidências de validade de uma versão brasileira da Fear of COVID-19 Scale.

This study sought to analyze the evidence of the validity of a Brazilian version of the Fear of COVID-19 Scale (FCV-19S), based on indicators relating to: (1) the internal structure; (2) the internal consistency; (3) the relation with external variables; and (4) the content. The instrument was culturally adapted, focusing on semantic and specifically Brazilian linguistic aspects. The Brazilian version of the FCV-19S was then applied, in a virtual environment, to 211 participants (72.98% female) with an average age of 37.07 years (SD=13.03), together with the Self-Perception Questionnaire on Mental Health in Pandemics and the Sociodemographic and Functional Questionnaire. The confirmatory factor analysis revealed one-dimensionality. The internal consistency indices obtained (Cronbach's alpha =0.921; McDonald's omega =0.926) can be considered high. The correlation between fear and obsessive thinking of the disease, generalized anxiety, generalized stress, phobic-avoidant behavior and bereavement due to the pandemic was found to be statistically significant. Evidence of the validity related to content, derived from a qualitative approach, were satisfactory. The conclusion drawn is that the Brazilian version of the FCV-19S proved to be adequate regarding the evidence of the expected validity.

The Psychometric Properties of Intention to Receive the COVID-19 Vaccine Scale Based on the Health Belief Model.

Acceptance of the SARS-CoV-2) COVID-19( vaccine is a very important factor to keep health workers safe. The study aimed to evaluate the psychometric properties of intention to receive the COVID-19 vaccine using a health belief model among health workers in Iran The study was a tools design study that was conducted in the period from February to March 2020, Iran Questionnaire items were designed using text review. The sampling method was multi-stage. Data were analyzed using descriptive statistics, confirmatory and exploratory factor analysis at a 95% confidence level using SPSS software version 16. The designed questionnaire had an appropriate content validity and internal consistency. Also, the exploratory factor analysis showed that a 5-factor structure was extracted and confirmatory factor analyses revealed that the conceptual five-factor structure of the measure had good fit indices. Reliability was evaluated using internal consistency. Cronbach Alpha coefficient was .82 and the intra-class correlation coefficient (ICC) was .9. It can be concluded that the instrument designed in the preliminary stage of psychometrics properties had good validity and reliability indicators. Also, the constructs of the health belief model well explain the determinants of the intention to receive the COVID-19 vaccine at the individual level.

Evaluating the psychometric properties of the fatigue severity scale using item response theory.

BACKGROUND: Fatigue is a common daily experience and a symptom of various disorders. While scholars have discussed the use of the Fatigue Severity Scale (FSS) using item response theory (IRT), the characteristics of the Japanese version are not yet examined. This study evaluated the psychometric properties of the FSS using IRT and assessed its reliability and concurrent validity with a general sample in Japan. METHODS AND MEASURES: A total of 1,007 Japanese individuals participated in an online survey, with 692 of them providing valid data. Of these, 125 participants partook in a re-test after approximately 18 days and had their longitudinal data analyzed. In addition, the graded response model (GRM) was used to assess the FSS items' characteristics. RESULTS: The GRM's results recommended using seven items and a 6-point scale. The FSS's reliability was acceptable. Furthermore, the validity was adequate from the results of correlation and regression analyses. The synchronous effects models demonstrated that the Multidimensional Fatigue Inventory (MFI) enhanced depression, and depression enhanced FSS. CONCLUSION: This study suggested that the Japanese version of the FSS should be a 7-item scale with a 6-point response scale. Further investigations may reveal the different aspects of fatigue assessed by the analyzed fatigue measures.

Reliability and validity evaluation of the chinese revision of the attitude towards adult vaccination scale.

BACKGROUND: Although vaccination is one of the critical interventions to address global health issues, inadequate vaccination rates has become an international challenge. Vaccine hesitancy is the key to affecting inadequate vaccination rates. According to the WHO SAGE working group's definition, vaccine hesitancy refers to delaying or refusing vaccination and has been ranked as one of the top 10 health threats. There has yet to be a scale that evaluates vaccination attitudes among Chinese adults. However, an attitude quantity, the adult vaccination attitude scale, has been developed to assess adult vaccination attitudes and reasons for vaccine hesitancy. OBJECTIVE: The Adult Attitudes to Vaccination Scale (ATAVAC) was initially developed by Professor Zoi Tsimtsiou et al. This study aimed to analyze the structure of the Chinese version of the ATAVAC and explore the relationship between adult vaccination attitudes, e-health literacy, and medical distrust. METHODS: After obtaining author permission for the initial scales, the study was translated using the Brislin back-translation method. 693 adults were enrolled to the study. To validate this hypothesis, participants finished the socio-demographic questionnaire, the Chinese version of the ATAVAC, the electronic Health Literacy Scale (e-HEALS) and the Medical Mistrust Index (MMI). The exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to examine the underlying structure of the factors of the Chinese version of the Adult Vaccination Attitude Scale and to measure its reliability and validity. RESULTS: The Cronbach's alpha coefficient for the Chinese version of the ATAVAC was 0.885, with Cronbach's alpha coefficients ranging from 0.850 to 0.958 for each dimension. The content validity index was 0.90, and the retest reliability was 0.943. The exploratory factor analysis (EFA) supported the 3-factor structure of the translation instrument, and the scale had good discriminant validity. The confirmatory factor analysis (CFA) revealed a degree of freedom of 1.219, a model fit index (GFI) of 0.979, a normative fit index (NFI) of 0.991, a Tucker-Lewis index (TLI) of 0.998, a comparability index (CFI) of 0.998 and a root mean square error of approximation (RMSEA) of 0.026. CONCLUSION: The results show that the Chinese version of the ATAVAC has demonstrated good reliability and validity. Hence, it can be used as an effective tool to assess vaccination attitudes among Chinese adults.

Psychometric evaluation of the Symptoms of Infection with Coronavirus-19 (SIC): results from a cross-sectional study and a phase 3 clinical trial.

BACKGROUND: The Symptoms of Infection with Coronavirus-19 (SIC) is a 30-item patient-reported outcome (PRO) measure scored by body system composites to assess signs/symptoms of coronavirus disease 2019 (COVID-19). In addition to cross-sectional and longitudinal psychometric evaluations, qualitative exit interviews were conducted to support the content validity of the SIC. METHODS: In a cross-sectional study, adults diagnosed with COVID-19 in the United States completed the web-based SIC and additional PRO measures. A subset was invited to participate in phone-based exit interviews. Longitudinal psychometric properties were assessed in ENSEMBLE2, a multinational, randomized, double-blind, placebo-controlled, phase 3 trial of the Ad26.COV2.S COVID-19 vaccine. Psychometric properties evaluated included structure, scoring, reliability, construct validity, discriminating ability, responsiveness, and meaningful change thresholds of SIC items and composite scores. RESULTS: In the cross-sectional study, 152 participants completed the SIC (mean age, 51.0 ± 18.6 years) and 20 completed follow-up interviews. Fatigue (77.6%), feeling unwell (65.8%), and cough (60.5%) were symptoms most frequently reported. SIC inter-item correlations were all positive and mostly moderate (r ≥ 0.3) and statistically significant. SIC items and Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) scores correlated as hypothesized (all r ≥ 0.32). Internal consistency reliabilities of all SIC composite scores were satisfactory (Cronbach's alpha, 0.69-0.91). SIC composite scores correlated moderately (r = 0.30-0.49) to strongly (r ≥ 0.50) with PROMIS-29 scores and Patient Global Impression of Severity (PGIS) ratings (all P < 0.01). A variety of signs/symptoms were cited in exit interviews, and participants considered the SIC straightforward, comprehensive, and easy to use. From ENSEMBLE2, 183 participants with laboratory-confirmed moderate to severe/critical COVID-19 were included (51.5 ± 14.8 years). Strong test-retest reliabilities were observed for most SIC composite scores (intraclass correlations ≥ 0.60). Statistically significant differences across PGIS severity levels were found for all but 1 composite score, supporting known-groups validity. All SIC composite scores demonstrated responsiveness based on changes in PGIS. CONCLUSIONS: The psychometric evaluations provided strong evidence for the reliability and validity of the SIC for measuring COVID-19 symptoms, supporting its use in vaccine and treatment trials. In exit interviews, participants described a broad range of signs/symptoms consistent with previous research, further supporting the content validity and format of the SIC.

Coronavirus disease 2019 (COVID-19) is a serious disease that continues to evolve globally. Researchers developed the Symptoms of Infection with Coronavirus-19 (SIC), a 30-item questionnaire designed for patients to report signs and symptoms of COVID-19. In this study, the researchers formally analyzed how well the SIC measures the patient experience with COVID-19, using survey and clinical trial data as well as telephone interviews. Adults with COVID-19 and at least 2 bothersome symptoms completed the web-based survey, and some of these individuals also participated in in-depth interviews. Participants in a clinical trial for a COVID-19 vaccine also completed the SIC measure. The SIC was compared with other commonly used questionnaires that evaluate patient experience. The most commonly reported symptoms of COVID-19 were fatigue, feeling unwell, cough, weakness, and headache. The items for individual symptoms (e.g., "cough") and combined scores for body systems (e.g., "respiratory system") performed well in statistical analyses. Participants found the SIC to be straightforward, comprehensive, and easy to use. The SIC may prove useful in the future for vaccine and treatment trials for COVID-19.

Psychometric properties of the environmental factors' questionnaire for undergraduate medical students taking online learning during COVID-19 pandemic: a cross-sectional study.

BACKGROUND: Environmental factors are important for students' learning during online classes, especially during a pandemic, such as COVID-19. This study aimed to validate the environmental factors' questionnaire during online learning. METHODS: A total of 218 undergraduate medical students at the Health Campus, Universiti Sains Malaysia, participated in a cross-sectional study that involved an online survey. Environmental factor scales were assessed with the nine-item lighting, noise, and temperature (LNT) scale and the six-item technology scale. Analysis was performed using confirmatory factor analysis (CFA). RESULTS: The English version of the LNT scale with nine items and three factors showed a good fit to the data, with no item deleted. For LNT, the composite reliability (CR) was 0.81, 0.81, and 0.84, respectively, while the average variance extracted (AVE) was 0.61, 0.59, and 0.6, respectively. The English version of the technology scale, with six items and one factor, also showed a good fit to the data, with no item deleted. The CR was 0.84, and the AVE was 0.51. CONCLUSIONS: The results provide psychometric evidence for environmental questionnaire scales in evaluating the factors associated with online learning among Malaysian university medical students. All items were retained and confirmed to fit the sample data.

[Psychometric properties of two surveys about beliefs towards vaccines in general and SARS-CoV-2 vaccine]. / Escala de creencias hacia las vacunas y hacia la vacuna contra el SARS-CoV-2: Evidencia de sus propiedades psicométricas.

BACKGROUND: Negative beliefs about vaccines can threaten herd immunity and pandemic control. Although beliefs about vaccines influence vaccination intention, there are no valid instruments that evaluate this in the Latin American population. AIM: To evaluate the psychometric properties of two scales that measure negative beliefs towards vaccines in general and against SARS-CoV-2 and provide evidence of their association with vaccination intention (convergent validity) in a Chilean sample. MATERIAL AND METHODS: Two studies were carried out. The first included 263 people who answered the beliefs towards vaccines in general scale (CV-G) and the beliefs towards the SARS-CoV-2 vaccine scale (CV-COVID). Exploratory factor analyses were conducted. In the second study, 601 people answered the same scales. Confirmatory factor analyses and structural equation modeling were performed to provide evidence of validity. RESULTS: Both scales had an unifactorial structure and excellent reliability and showed associations with the intention of vaccination against SARS-CoV-2, providing evidence of convergent validity. CONCLUSIONS: The scales evaluated here are reliable and valid measures that showed associations with vaccination intention in the Chilean population.

Anxiety in Brief: Assessment of the Five-Item Trait Scale of the State-Trait Anxiety Inventory in South Africa.

The current study examined the psychometric properties of a short form of the trait scale of the Spielberger State-Trait Anxiety Inventory. Participants consisted of a convenience sample of students (n = 322) who completed the five-item version of the trait scale of the State-Trait Anxiety Inventory, the Perceived Stress Scale, the nine-item version of the Beck Hopelessness Scale, the 10-item version of the Center for Epidemiological Studies Depression Scale, and the Post-Traumatic Stress Disorder Checklist. We used classical test theory and item response theory (Rasch and Mokken analyses) to examine the psychometric properties of a previously proposed five-item version of this scale. These approaches confirmed that the five-item measure of anxiety had satisfactory reliability and validity, and also confirmed that the five items comprised a unidimensional scale.

Factorial structure, reliability, and construct validity of the Generalized Anxiety Disorder 7-item (GAD-7): Evidence from Malaysia.

Generalized anxiety disorder (GAD) is one of the most common mental disorders in Malaysia. Psychometrically sound measurements are urgently needed to assess anxiety symptoms. The extensively used Generalized Anxiety Disorder 7-item (GAD-7) is a promising candidate. However, studies on its factorial validity show mixed findings. While the one-factor solution has been replicated in different cultural contexts, some studies found different factorial structures instead. This study aimed to clarify the factorial validity of the English version of the GAD-7 in the Malaysian context. The responses collected from 1272 emerging to older adults in Malaysia were randomly divided into two halves and submitted to exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) respectively. Four acceptable models were explored in EFA ranging from unidimensional factor with 7 items to 3-factor models with 6 items. The four models revealed in EFA and the other competing models found in past studies were then examined and compared using CFA. The 6-item second-order model with a general factor of anxiety and three first-order factors with two items respectively (i.e., GAD-6) showed a more harmonic result and hence, is preferable. Moreover, the GAD-6 and its three subscales also showed satisfactory internal consistency and construct validity. This study uncovers a new and unique factorial structure of the GAD screening tool that fits in the Malaysian context. The scale may reveal GAD symptomatic dimensions that guide clinical interventions.

Spanish psychometric properties of the moral distress scale-revised: a study in healthcare professionals treating COVID-19 patients.

BACKGROUND: Moral distress appears when a healthcare professional is not able to carry out actions in accordance with their professional ethical standards. The Moral Distress Scale-Revised is the most widely used to assess levels of moral distress, but it is not validated in Spanish. The aim of the study is to validate the Spanish version of the Moral Distress Scale - utilised within a sample of Spanish healthcare professionals treating COVID-19 patients. METHODS: The original (english) and the portuguese and french versions of the scale were translated into spanish by native or bilingual researchers and reviewed by an academic expert in ethics and moral philosophy as well as by a clinical expert. RESEARCH DESIGN: Descriptive cross-sectional study carried out using a self-reporting online survey. The data was collected between June- November 2020. A total of 661 professionals responded to the survey (N = 2873). PARTICIPANTS: healthcare professionals with more than two weeks of experience treating COVID-19 patients at the end of their life and working in the public sector of the Balearic Islands Health Service (Spain). Analyses included descriptive statistics, competitive confirmatory factor analysis, evidence on criterion-related validity and estimates of reliability. The study was approved by the Research Ethics Committee at the University of Balearic Islands. RESULTS: An unidimensional model in which a general factor of moral distress explained by 11 items of the Spanish version of the MDS-R scale was an adequate representation of the data: χ2(44) = 113.492 (p 0.001); Comparative Fit Index = 0.965; Root Mean Square Error of Approximation = 0.079[0.062,0.097]; and Standarized Root Mean-Square = 0.037. Evidence of reliability was excellent: Cronbach's alpha = 0.886 and McDonald's omega = 0.910. Moral distress was related to discipline, with nurses having statistically significant higher levels than physicians. Additionally, moral distress successfully predicted professional quality of life, with higher levels of moral distress being related to poorer quality of life. CONCLUSIONS: The Spanish version of Moral Distress Scale-Revised can be used as a reliable and valid measurement tool for the evaluation of moral distress experienced by health professionals. This tool will be highly useful for managers and applicable to a variety of healthcare professionals and settings.

Adapting the COVID Stress Scale (CSS) to investigate the level of stress among Hong Kong Chinese people 1 year after the COVID-19 pandemic.

BACKGROUND: Stress is a crucial driver that affects hygiene behavior. The Hong Kong population lacks a COVID-19 or pandemic related stress measure investigating the COVID-19 related stress after one year of outbreak. DESIGN AND METHODS: The original COVID Stress Scale (CSS) was translated and culturally adapted into the Chinese (Cantonese) version (CSS-C). Six hundred and twenty-four participants were recruited from the general public to examine the internal consistency, and concurrent and convergent validity of the CSS-C. The test-retest reliability of CSS-C was examined using 39 university students. RESULTS: People with old age, women, single, low educational level and borderline and abnormal levels of anxiety and depression were likely to perceive high level of COVID-19 related stress. All CSS-C subscales demonstrated good internal consistency, moderate to good test-retest reliability, and weak to moderate correlations with various mental health-related measures. DISCUSSION: The CSS could help monitor the stress associated the current and potential future pandemics.

The Thai version of the COVID-19 Yorkshire Rehabilitation Scale: a valid instrument for the psychometric assessment of the community members in Bangkok, Thailand.

BACKGROUND: Coronavirus disease 2019 (COVID-19) can develop into a long-term COVID in some cases, which can have a major impact on various health systems requiring appropriate treatment involving multi-disciplinary healthcare. The COVID-19 Yorkshire Rehabilitation Scale (C19-YRS) is a standardized tool widely used for screening the symptoms and severity of long-term COVID. Translation of the English version of the C19-YRS into the Thai language and testing it is essential for the psychometric evaluation of the severity of the long-term COVID syndrome prior to providing rehabilitation care for community members. METHODS: Forward-and back-translations including cross-cultural aspects were conducted in order to develop a preliminary Thai version of that tool. Five experts evaluated the content validity of the tool and produced a highly valid index. A cross-sectional study was then conducted on a sample of 337 Thai community members recovering from COVID-19. Assessment of internal consistency and individual item analyses were also performed. RESULTS: The content validity resulted in valid indices. The analyses showed that 14 items had acceptable internal consistency, based on the corrected item correlations. However, five symptom severity items and two functional ability items were deleted. The Cronbach's alpha coefficient of the final C19-YRS was 0.723, indicating acceptable internal consistency and reliability of the survey instrument. CONCLUSIONS: This study indicated that the Thai C19-YRS tool had acceptable validity and reliability for the evaluation and testing of the psychometric variables in a Thai community population. The survey instrument also had acceptable validity and reliability for screening the symptoms and severity of long-term COVID. Further studies are warranted in order to standardize the various applications of this tool.

Psychometric properties of the traditional Chinese version of the COVID Stress Scales in Hong Kong.

Introduction: The COVID Stress Scales (CSS) assess six domains of COVID-19-related stress, including (a) COVID danger, (b) COVID socioeconomic consequences, (c) COVID xenophobia, (d) COVID contamination, (e) COVID traumatic stress symptoms, and (f) COVID compulsive checking. Although the CSS have been validated in various cultural contexts, their psychometric properties in Hong Kong have not been examined. This study endeavors to validate the traditional Chinese version of the 36-item CSS (CSS-36) and the 18-item CSS (CSS-18) in Hong Kong. Method: Participants were 521 Hong Kong undergraduate students (61% female) aged from 18 to 26 years (M = 20.65, SD = 1.56). An online questionnaire was used for data collection. Results: The results of confirmatory factor analyses supported a six-factor structure for both the CSS-36 and the CSS-18. Multiple-group confirmatory factor analyses established the gender invariance of the six-factor model for both the CSS-36 and the CSS-18. The CSS-36 and the CSS-18 exhibited good internal consistency reliability and concurrent validity with fear of COVID-19 and negative emotional states. Discussion: The findings offer evidence for the psychometric properties of the traditional Chinese version of the CSS-36 and the CSS-18 in the Hong Kong context.

Physical performance testing in post-COVID-19 patients: protocol for a systematic review of psychometric measurement properties.

INTRODUCTION: COVID-19 is an infectious disease that causes severe acute respiratory syndrome. A large variety of exercise capacity tests are used for the evaluation of post-COVID-19 patients, but the psychometric properties of these exercise tests remain undetermined in this population. This study aims to critically appraise, compare and summarise the psychometric properties (validity, reliability and responsiveness) of all physical performance tests that are used to assess exercise capacity in post-COVID-19 patients. METHODS AND ANALYSIS: This systematic review protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. We will include studies with hospitalised adult post-COVID-19 patients (aged 18 years or older and with a confirmed diagnosis of COVID-19). The research will cover randomised controlled trials (RCTs), quasi-RCTs and observational studies published in English and performed in the following settings: hospital, rehabilitation centre, outpatient clinic. We will search the following databases with no date restrictions: PubMed/MEDLINE, EMBASE, SciELO, Cochrane Library, CINAHL and Web of Science. Two authors will independently assess the risk of bias (using the Consensus-Based Standards for the Selection of Health Measurement Instruments Risk of bias checklist) and the certainty of evidence (using the Grading of Recommendations, Assessment, Development and Evaluations). According to the results obtained, data will be meta-analysed or reported narratively. ETHICS AND DISSEMINATION: No ethical approval is required for this publication since it will be based on published data. Results of this review will be disseminated via peer-reviewed publications and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42021242334.

Exploratory Factor Analysis of a French Adapted Version of the Substance Abuse Attitude Survey among Medical Students in Belgium.

To evaluate the impact of a new Substance Use Disorder (SUD) education program on medical students' attitudes, we selected the Substance Abuse Attitude Survey (SAAS) questionnaire, which we adapted to our curriculum and cultural context. To validate this adapted version, we conducted an exploratory factor analysis following the administration of our 29-item bSAAS questionnaire to 657 medical students in Belgium (response rate: 71.1%). Twenty-three items correlated to three factors; namely, "Stereotypes and moralism", "Treatment optimism" and "Specialized treatment" were retained (70% of total variance explained, Cronbach's alpha = 0.80) and constituted the new questionnaire called beSAAS. The factor "Specialized treatment" stood out from previous studies, which could be explained by our target population and the impact of the formal, informal and hidden curricula in medical education. This study was able to highlight certain factors influencing stereotypical representations such as age, gender, origin, personal or professional experience with substance use. Our study allowed us to retain the beSAAS as a good questionnaire to evaluate SUD stigma and highlighted interesting findings to improve SUD training in medicine. Further studies are needed to complete its validity and reliability.

Evaluating depression anxiety and stress assessment before and during the COVID-19 pandemic using generalisability theory.

The current study investigated the assessment of depression, anxiety, and stress during normal and COVID-19 pandemic conditions. Generalisability theory (G-theory) was applied to examine stable and dynamic aspects of psychological distress and the overall reliability of the Depression, Anxiety and Stress Scales (DASS-21), using data from two independent samples collected on three occasions with 2- to 4-week intervals. The US data (n = 115) was collected before the COVID-19 pandemic, and the New Zealand (NZ) data (n = 114) was obtained during the pandemic. The total DASS-21 demonstrated excellent reliability in measuring enduring symptoms of psychological distress (G = .94-.96) across both samples. While all DASS-21 subscales demonstrated good reliability with the pre-pandemic US sample, the subscales' reliability was below an acceptable level for the NZ sample. Findings from this study indicate that the overall psychological distress is enduring and can be reliably measured by the DASS-21 across different conditions and populations, while shifts across depression, anxiety and stress levels are likely during emergency and uncertainty, as seen in the COVID-19 pandemic.

Validity and reliability of the Pandemic Fatigue Scale (PFS) in the Turkish population.

BACKGROUND: The measures developed to fight the COVID-19 pandemic caused fear, stress and anxiety in people over time. It was reported that pandemic fatigue, associated with the gradual loss of motivation to follow the implemented protective measures, emerged in societies. OBJECTIVE: This cross-sectional-methodological study aimed to validate the Turkish version of the Pandemic Fatigue Scale, developed by Lilleholt et al. (2020). METHODS: A web-based questionnaire was conducted to examine the validity and reliability of the Turkish version of the PFS. 1149 participants from all regions in Turkey participated. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed. RESULTS: As a result of the KMO and Bartlett's Test of Sphericity, the scale was suitable for the factor analysis. According to EFA, the scale has two sub-factors. The first sub-factor explained 48.7%, and the second sub-factor explained 16.7% of the total variance. Factor loadings of items varied between 0.67 and 0.89. CFA shows that acceptable fit values were obtained for the RMSEA, GFI, AGFI, CFI, NFI and IFI fit indices. CONCLUSIONS: The results support that PFS is a valid and reliable screening tool that can be used to measure the phenomenon of pandemic fatigue.

Validation of Generalized Anxiety Disorder 6 (GAD-6)-A Modified Structure of Screening for Anxiety in the Adolescent French Population.

Anxiety disorders remain underdiagnosed and undertreated, especially in child and adolescent populations. This study aimed to examine the construct validity of the Generalized Anxiety Disorder Scale 7 (GAD-7) in a sample of French adolescents by combining the Classical Test Theory (CTT) and the Item Response Theory (IRT) and to assess the invariance of items. A total of 284 adolescents enrolled in school in the Lorraine region were randomly selected to participate in a cross-sectional study. A psychometric evaluation was performed using a combination of CTT and IRT analyses. The study of psychometric properties of GAD-7 revealed poor adequation to the sample population, and engendered the deletion of one item (#7) and the merger of two response modalities (#2 and #3). These modifications generated the new GAD-6 scale, which had a good internal consistency reliability (Cronbach α = 0.85; PSI = 0.83), acceptable goodness-of-fit indices (χ2 = 28.89, df = 9, P = 0.001; RMSEA (90% CI) = 0.088 [0.054; 0.125]; SRMR = 0.063; CFI = 0.857), and an acceptable convergent validity (r = -0.62). Only one item (#5) had a consistent Differential Item Functioning (DIF) by gender. This study evaluated the structure of the GAD-7 scale, which was essentially intended at discriminating adolescent patients with high levels of anxiety, and adapted it to a population of adolescents from the general population. The GAD-6 scale presents better psychometric properties in this general population than the original GAD-7 version.
