Assessing obsessive-compulsive symptoms in a subclinical and clinical sample: the development of the Hungarian version of the OCI-R.

OBJECTIVES: The prevalence of clinical obsessive-compulsive disorder (OCD) is around 1-2% in the population. Questionnaires, such as the OCI-R, are a useful tool in the diagnositc process. The purpose of this study was to develop the Hungarian version of the OCI-R, examine its validity and reliability, and its ability to differentiate between clinical and subclinical OCD. METHODS: Confirmatiory factor analysis was carried out on the subclinical sample (N = 4301). Reliability analysis was carried out on both samples, and Mann-Whitney tests were used to compare the two samples. RESULTS: The six-factor structure identical to the original was confirmed by confirmatory factor analysis. In the subclinical sample, all scales but Neutralizing had good reliability. Reliability analysis on the clinical sample (N = 26) showed good Cronbach's alpha values for all scales except for Hoarding. There were significant differences between the two groups on three scales: Neutralizing, Washing, and Obsessing, with the clinical group scoring significantly higher on these scales. The average score for Checking, Hoarding, and Ordering was higher in the subclinical sample, although the difference was not significant. CONCLUSION: The results highlight the advantages of symptom severity scales, such as the OCI-R, in the diagnostic process of obsessive-compulsive disorder.

The Holland Sleep Disorders Questionnaire: Factorial structure and measurement invariance in a psychiatric sample relative to the general population.

OBJECTIVES: Although common, sleep disorders often remain undiagnosed in psychiatric patients. A screening instrument, like the Holland Sleep Disorders Questionnaire (HSDQ) could improve this. Previous work indicated a 6-factor structure for the HSDQ, but this hasn't been investigated in psychiatric patients. METHODS: HSDQ data was collected in a psychiatric-outpatient sample (n = 1082) and general-population sample (n = 2089). Internal reliability of the HSDQ was investigated and Confirmatory Factor Analyses (CFA) were used to compare 1-, 6-, and second-order 6-factor models in both samples. Next, multigroup-CFA was used to investigate measurement invariance. RESULTS: Except for one subscale, internal reliability was acceptable in both samples. The 6-factor structure model fitted best in both samples and investigation of measurement invariance showed evidence for equality of the overall factor structure (configural invariance). Addition of equality constraints on factor loadings (metric invariance) and item thresholds (scalar invariance) showed good fit for all fit statistics, except for one. Exploratory analyses identified three items for metric and three different items for scalar invariance explaining this non-invariance. CONCLUSION: The HSDQ has a 6-factor structure in psychiatric patients, which is comparable to the general population. However, due to the observed non-invariance, users should be cautious with comparing HSDQ scores between psychiatric and general populations.

Psychometric characteristics of the Spanish version of the HIV Symptom Index.

BACKGROUND: The aim of this study was to determine the psychometric properties of the Spanish-language version of the HIV-Symptom Index (HIV-SI) questionnaire in Spanish patients undergoing antiretroviral therapy. METHODS: Between 2014 and 2016, an observational, multicenter, prospective cohort study was conducted in seventeen Spanish hospitals to validate HIV-SI questionnaire in terms of: construct validity (confirmatory factor analysis), internal consistency (Cronbach's alpha), convergent validity (Pearson's correlation coefficient) and Known-group validity. In addition, a sensitivity to change analysis was also performed. RESULTS: A total of 232 patients were included in the study. They had a mean age of 46.17 (SD9.82) and were 75% male. The median overall score for the HIV-SI was 10 (IQR 4- 19.5) and the most common symptoms reported were feelings of nervousness or anxiety, fatigue or energy loss, feeling sad or depressed, stomach pain or bloating, and difficulty sleeping. In the current study, the Spanish HIV-SI questionnaire showed a high internal consistency (α = 0.89) and adequate construct validity (CFI and TLI > 0.90). When contrasted with the MOS-HIV questionnaire, an inverse correlation was found. It showed a good association with the mental (r=-0.61; P < 0.0001) and physical score (r=-0.60; P < 0.0001). In a multivariate analysis, the age of the patient, female condition, hepatitis C coinfection, concomitant treatment and non-adherence resulted in a higher HIV-SI score. CONCLUSIONS: Our study has shown that the Spanish HIV-SI is a valid and reliable self-administered PROM for routine measurement of patient- reported symptoms among Spanish patients on antiretroviral treatment.

Psychometric Properties under EFA, CFA, Measurement Invariance, and IRT Models for Older Adults' First Aids Knowledge Scale among Iranian Grandparents: The Modified Scale.

This research aims to create and evaluate an assessment tool termed Older Adults' First Aid Knowledge Scale, which measures the knowledge and attitude of Iranian grandparents about first aid. In accordance with COSIM guidelines, 485 individuals in southern Iran completed the instrument as part of a psychometric investigation. Rasch partial credit model (PCM), exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and receiver operating characteristic (ROC) analysis were used to analyze the results. The final version of OFAKS consisted of 18 items that were validated through EFA, CFA, and item response theory (IRT) analysis. All items showed measurement invariance and consecutive response groupings in the predictable order, and the instrument had strong internal consistency. Although Rasch's analysis demonstrated the significance of OFAKS, further investigations and testing in different settings are required to confirm the validity of the tool.

Investigating the psychometric properties of the Persian version of the Quality of Life Questionnaire for Women Infected with HPV (EQUALI-HPV).

INTRODUCTION: People with human papiloma virus (HPV) struggle with numerous challenges and needs in physical, and psychological aspects of quality of life related to this virus. Several studies have recommended counseling interventions to improve the quality of life for these individuals. There is also a need for standardized and normalized instruments in Iran to evaluate the effect of educational and therapeutic interventions on the quality of life of these patients. Therefore, this study was conducted in gynecological cancer clinics in Kerman and Mashhad to investigate the psychometric properties of the Persian version of the "Quality of Life Questionnaire for Women Infected with HPV". METHODS: This study cross-sectional study included 580 women infected with HPV referred to Kerman and Mashhad's gynecologic cancer clinics. The samples were selected using convenience sampling method in 2023. Content validity, face validity, and construct validity were assessed using explanatory factor analysis (EFA) and confirmatory factor analysis (CFA). RESULTS: The results of the content validity assessment, which included the Content Validity Index (CVI) and the Content Validity Ratio (CVR), indicated strong content validity. Additionally, qualitatively confirmed face validity, further supports these findings. The results of the EFA revealed that the Persian version of the EQUALI-HPV questionnaire has a 6-factor structure, with 34 items remaining from the 54 items. These 6 factors accounted for 48.9% of the variance and were confirmed by confirmatory factor analysis and using robust root mean square error of approximation (RMSEA = 0.054), comparative fit index (CFI = 0.928), and Tucker-Lewis index (TLI = 0.920). The content validity results showed that all the items had a good validity ratio and index. Cronbach's alpha and Raykov's rho were greater than 0.7 for all dimensions. CONCLUSION: The results showed that the Persian version of the "Quality of Life Questionnaire for Women Infected with HPV" had acceptable validity and reliability and can be utilized to measure the quality of life of these people and conduct psychological studies.

Validation of the parents' version of the KINDLR and Kiddy Parents questionnaire in a South African context.

BACKGROUND: This study aimed to assess the usefulness of the parent version of the KINDLR and the additional items of the Kiddy Parents questionnaire in the South-African context and to validate it as an appropriate tool for measuring health-related quality of life (HRQoL). METHOD: The ExAMIN Youth SA study was designed to investigate lifestyle behaviours, including psychosocial factors that may adversely impact on cardiovascular health of children. Construct validity was examined by using exploratory and confirmatory factor analysis, while internal consistency was tested by Cronbach's alpha. The final factor structure was confirmed by model fit indices. RESULTS: The study included children (n = 1088) aged between 5 and 10 years in North-West, South Africa. The reliability coefficients of the original factors could not be reproduced in this data set, with the Cronbach's alphas ranging between 0.46 and 0.78. With exploratory factor analysis, including the additional items, our data supported a 7-factor structure with acceptable internal consistency (Cronbach's alpha: 0.68-0.79; Omega: 0.75-0.85) and acceptable model fit indices (CFI: 0.91; TLI: 0.90; RMSEA: 0.05; SRMR: 0.07). Two factors (emotional wellbeing and everyday functioning) further split into separate factors for positive and negative experiences related to each of these dimensions. CONCLUSION: We confirmed a new factor structure of the parent version of the KINDLR and the additional items of the Kiddy Parents questionnaire, which can be used in the African context. Although the new factor structure has great overlap with the original structure, some items did not contribute to the factors as expected. Language and cultural differences between the original German group and the current South African study group resulted in a different factor structure.

The Inventory of Personality Organization-Reality Testing Subscale and Belief in Science Scale: Confirmatory factor and Rasch analysis of thinking style measures.

The Inventory of Personality Organization-Reality Testing Subscale (IPO-RT) and Belief in Science Scale (BIS) represent indirect, proxy measures of intuitive-experiential and analytical-rational thinking. However, a limited appraisal of factorial structure exists, and assessment of person-item functioning has not occurred. This study assessed the IPO-RT and BIS using confirmatory factor analysis (CFA) and Rasch analysis with a sample of 1030 participants (465 males, 565 females). Correlation analysis revealed a negative, moderate relationship between the measures. CFA supported a bifactorial model of the IPO-RT with four bifactors (Auditory and Visual Hallucinations, Delusional Thinking, Social Deficits, and Confusion). A one-factor model best fitted the BIS. Satisfactory item/person reliability and unidimensionality was observed for both measures using Rasch analysis, and items generally exhibited gender invariance. However, IPO-RT items were challenging, whereas BIS items were relatively easy to endorse. Overall, results indicated that the IPO-RT and BIS are conceptually sound, indirect indices of intuitive-experiential and analytical-rational thinking. Acknowledging the breadth of these thinking styles, a useful future research focus includes evaluating the performance of IPO-RT and BIS alongside objective tests.

Development of Chinese college students' perception teacher differential behavior scale and its reliability and validity test.

OBJECTIVE: To compile a scale of Chinese college students' perception of teachers' differential behavior and to provide a reference for college students to establish correct life values, promote college students' physical and mental health, and reduce teachers' differential treatment. METHODS: Open-ended questionnaires and expert interviews were used to conduct interviews and correspondence with 58 college students, ten psychologists, and six psychologists to form an initial questionnaire. Then, the scale's exploratory factor analysis, confirmatory factor analysis, and reliability and validity test were conducted on 7053 college students from 18 universities in 6 provinces (municipalities directly under the Central Government). RESULTS: The Chinese college students' perception of teachers' differential behavior scale has two dimensions: teacher prejudice and preference. Each dimension includes three aspects: emotional feedback, behavior orientation, and opportunity privilege, and each aspect have a total of 4 items. The consistency test coefficients of each dimension and each factor of the prepared scale are all above 0.7, and the split-half reliability is above 0.6. Confirmatory factor analysis shows that the six-factor structural model fits well (χ2/df = 4.287, RMSEA = 0.066, CFI = 0.950, TLI = 0.919). Using the generalized anxiety disorder scale and the patient health questionaire-9items as empirical criteria, each factor in the scale demonstrated significant correlations with both the GAD scale and the patient health questionaire-9items. CONCLUSIONS: The Chinese college students' perception of teachers' differential behavior scale has a two-dimensional six-factor structure and has good reliability and validity. It can be used as an effective tool to measure Chinese college students' perceived teacher differential behavior.

[Confirmatory factor analysis of the Chinese version of tinnitus handicap inventory].

Objective: To explore the validity of the Chinese version of tinnitus handicap inventory (THI-CM) using confirmatory factor analysis. Methods: A cross-sectional study was carried out. The patients who complained of tinnitus and visited the Department of Otolaryngology, Head and Neck Surgery at West China Hospital of Sichuan University from March 15 to June 28, 2023 were included. All participants underwent pure tone audiometry and acoustic impedance testing before filling out THI-CM, and the results were subjected to confirmatory factor analysis. Results: A cross-sectional study was carried out. A total of 300 patients aged (47±13) years participated in this study. There were 175 females (58.3%) and 125 males (41.7%). The confirmatory factor analysis showed that χ2/df was 1.597<3.00, root mean square error of approximation (RMSEA) was 0.039<0.05, and standardized root mean square residual (SRMR) was 0.091>0.08. The incremental fit index (IFI), Tucker-Lewis index (TLI), comparative fit index (CFI), and goodness of fit index (GFI) were 0.960, 0.954, 0.960, and 0.902, respectively. The overall model fitted well. Except for one item with a load of 0.493, the load values of the other items were between 0.553 and 0.771. The composite reliability (CR) values of the three dimensions of the scale were between 0.769 and 0.901 (all CR>0.7). The average variance extracted (AVE) values ranged from 0.403 to 0.505 (all AVE<0.7), indicating poor convergent validity of the scale. The square value of AVE in each dimension of the scale was smaller than the correlation coefficient between factors, indicating poor discriminant validity of the scale. Conclusions: The THI-CM has good structural validity, which can be used as an effective tool to evaluate the overall severity of tinnitus. However, its convergent validity and discriminant validity are poor.

Living with long-term conditions: validation of a new instrument for family caregivers in a Spanish-speaking population.

INTRODUCTION: Optimising the management of chronicity has been a global challenge for decades. Individuals with long-term conditions (LTCs) and their families live with them for years. Thus, it is necessary to include both of their perspectives in the management and adaptation of the interventions proposed. The psychometric properties of the living with LTCs scale from the perspective of the family caregiver are unknown. The objective of the present study is to describe the psychometric properties of the EC-PC-Fam in a Spanish-speaking population. METHODS: An observational, cross-sectional study was performed with a retest of part of the sample. The fit of the model was optimised with a factorial analysis, and the psychometric properties were verified. RESULTS: A sample of 311 caregivers was recruited. Most of them were women (68.2%) and had a mean age of 58.29±9.91 years (range: 32-84 years). The initial version did not obtain acceptable fit scores. To improve the fit, different versions were tested, refining the distribution of the items until optimisation was reached in V.10 (19 items). Cronbach's alpha was 0.81 for the scale as a whole. The intraclass correlation coefficient was 0.77. The EC-PC-Fam scale is strongly and inversely correlated with a scale that measures the burden of the caregiver (rs=-0.46), and moderately related to the health-related quality of life (rs=0.373) and social support (rs=0.38). CONCLUSIONS: The EC-PC-Fam scale from a family perspective is defined as a promising tool for promoting personalised care and for optimising the management of LTCs, and a new approach that includes family caregivers is proposed for clinical practice. The scale is an instrument with a moderate fit and optimum psychometric properties to measure living with LTCs from the perspective of a family caregiver. New validation studies are recommended to verify the fit of the proposed factorial solution.

Development and validation of a Disorganised Thoughts Scale: a new measure to assess thinking difficulties in the general population.

BACKGROUND: Disordered thinking is a condition that can manifest in not only clinical cases (e.g., psychotic disorders), but also the wider general population. However, there is no current method to measure the specific cognitive processes experienced during such a condition. Therefore, this study aimed to develop a new self-report measure, the Disorganised Thoughts Scale (DTS), that can assess disorganised thinking in the general population. METHODS: To achieve this aim, a survey was developed and shared online with four independent samples, including a sample of Australians in the general population (N = 321) and three samples (N = 200 each) that were controlled for their substance use (i.e., frequent alcohol and cannabis use; non-frequent substance use). Exploratory and confirmatory factor analyses, and reliability analyses, were used to test the internal validity, whilst correlational analyses were implemented to examine the external validity. RESULTS: The exploratory factor analysis revealed a two-factor structure (10 items each) measuring Positive thought disorder (i.e., accelerated, uncontrollable, and incongruent thinking) and Negative thought disorder (i.e., inhibited, disjointed, and disorientated thinking). This internal structure was confirmed with subsequent confirmatory factor and reliability analyses (α = 0.90 to 0.97) in the three substance-controlled groups. Concurrent validity was also supported, as the DTS exhibited strong correlations with established measures of general cognitive difficulties, specific self-regulatory dysfunctions, and psychopathological symptomology. Finally, the measure was also shown to be significantly higher in cohorts who exhibited a higher degree of psychological distress and who frequently used substances (i.e., alcohol and cannabis). CONCLUSIONS: Overall, this study provided preliminary evidence to suggest that the DTS is a sound measure of disorganised thought that is linked to psychopathology and substance use in non-clinical populations. The measure could be used in future research which seeks to better understand how thinking effects, and is affected by, various psychological conditions.

The Translated and Adapted Brazilian Version of the Behavioral Enabling Scale for Family Members of Psychoactive Substance Users: An Analysis of the Factorial Structure and Internal Consistency.

OBJECTIVE: The enabling behaviors of family members of psychoactive substance users can be crucial in maintaining addiction. There are no psychometrically evaluated instruments to measure the frequency of the enabling behaviors of family members of psychoactive substance users. Therefore, this study aimed to assess the internal consistency and factor structure of the Behavioral Enabling Scale. DESIGN: A cross-sectional study was carried out, with a secondary analysis of data collected from 400 family members of psychoactive substance users that used a hotline service in Brazil. Exploratory factor analysis was conducted with an initial sample of 200 protocols, and with the remaining 200 protocols, a confirmatory factor analysis was conducted. RESULTS: The internal consistency estimate proved entirely satisfactory in both samples, where the first presented a Cronbach's alpha of 0.76 and the second had a consistency estimate of 0.79. Factor analysis was conducted using a shortened version of the instrument, with 15 items, during which six factors that cover 65% of the scale's explained variance were extracted. KMO = 0.68 and Bartlett's test of sphericity = X2 (gl = 153) 497.201, p < 0.0001, were significant. CONCLUSION: The Brazilian version of the Behavioral Enabling Scale is a valid tool that measures the frequency of the enabling behaviors of family members of psychoactive substance users. The measurement instrument enables further investigations into the behavior of family members regarding the use of psychoactive substances by their relatives.

Body Size Measurements Grouped Independently of Common Clinical Measures of Metabolic Health: An Exploratory Factor Analysis.

BACKGROUND: Obesity is commonly aggregated with indices of metabolic health. Proponents of body positivity approaches question whether body size is a determinant of health and well-being. Our objective was to conduct an exploratory factor analysis (EFA) to determine if body size measurements factor load with or independent of metabolic health measures. METHODS: The EFA was conducted on n= 249 adults using baseline data from four weight loss trials (Sample 1: n = 40; Sample 2: n = 52; Sample 3: n = 53; Sample 4: n = 104). An EFA of nine items (systolic blood pressure [SBP], diastolic blood pressure [DBP], hemoglobin A1c [HbA1c], HDL-cholesterol [HDL], LDL-cholesterol [LDL], total cholesterol [TC], body mass index [BMI], body fat percent BF%], and waist circumference [WC]) was conducted with oblique rotation. RESULTS: Three factors were retained, which produced a model explaining 87.5% of the variance. Six items loaded strongly (>0.8) under three components and were selected for retention (Factor 1: LDL and TC; Factor 2: BMI and WC; Factor 3: SBP and DBP). CONCLUSION: Body size measures loaded separately from measures of metabolic health and metabolic health were further split into lipid- and blood pressure-focused factors. These results support weight-neutral interventions to improve overall health and well-being.

Development and validation of a questionnaire (QSPC-Q) for assessment of quality and strengthening of primary care in Brazil.

The performance evaluation of services through instruments is relevant, as it can support thoughts, actions and political approaches to meet a social need. The objective of the article was to develop and validate the Quality and Strengthening of Primary Care Questionnaire (QSPC-Q) for professionals and users based on Starfield attributes and Donabedian pillars. A mixed sequential study was performed to develop the QSPC-Q. The test was applied to 149 doctors and 795 users of basic health units. Psychometric properties was assessed by testing internal consistency using Cronbach's alpha and exploratory factor analysis. Reproducibility od scale was assessed using intraclass cognitive and test-retest correlation. The final version of the follow-up consisted of 45 items aimed at physicians (Cronbach's alpha = 0.921) and 33 at users (Cronbach's alpha = 0.86); the intraclass respiratory capacity was 0.88. An exploratory factor analysis identified 13 factors associated with the pattern components. A short version with 29 items for professionals was also elaborated. Professional QSPC-Q (short and braided versions) and user QSPC-Q were valid.

Psychometric properties of the social determinants of health questionnaire (SDH-Q): development and validation.

BACKGROUND: The influence of social determinants of health (SDH) on sustainable development goals (SDG) has gained attention in recent years. However, there is a scarcity in the availability of valid and reliable instruments to assess the multiple aspects of SDH. Hence, this study was conducted to develop a brief self-reported measure for assessing SDH. METHOD: A cross-sectional survey was conducted among university undergraduate students in Nigeria. The study consisted of 300 participants in the EFA (males 55.7%, females 44.3%) and 430 participants in the CFA (males 54.0%, females 46.0%). Participants were selected using a convenience sampling approach to assess their perceptions regarding SDH. Content Validity Index (CVI), Face Validity Index (FVI), Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), Composite Reliability (CR), Average Variance Extracted (AVE), Cronbach's alpha, and Intraclass Correlation Coefficient (ICC) were computed to determine the psychometric properties of the newly developed SDH scale. RESULTS: In the EFA, two factors were extracted (structural determinants of SDH and intermediary determinants of SDH), with all 20 items retained. The total variance explained by the EFA model was 61.8%, and the factor correlation was 0.178. The Cronbach's alpha values of the two factors were 0.917 and 0.939. In the CFA, the initial model did not fit the data well based on fit indices. After several re-specification of the model, the final re-specified measurement model demonstrated adequate fit factor structure of the SDH scale with two factors and 20 items (CFI = 0.943, TLI = 0.930, SRMR = 0.056, RMSEA = 0.053, RMSEA p-value = 0.220). The CR was 0.797 for structural determinants of SDH and 0.794 for intermediary determinants of SDH. The ICC was 0.938 for structural determinants of SDH and 0.941 for intermediary determinants of SDH. CONCLUSION: The findings indicate that the SDH scale has adequate psychometric properties and can be used to assess the perceived level of SDH. We recommended that this tool be tested in other populations with diverse age groups and other demographic characteristics.

Adaptation and psychometric assessment of a sexual and reproductive empowerment scale in Arabic among refugee and non-refugee adolescent girls.

BACKGROUND: Sexual and reproductive empowerment (SRE) is an important determinant of women's and girls' health yet measuring it is complex due to cultural and domain-specific variations. This study describes the process of adapting an SRE scale consisting of four domains (self-efficacy; future orientation; social support; and safety) and testing its psychometric properties among Arabic speaking adolescent girls in Lebanon. METHODS: An SRE scale developed in a Western context was adapted in four steps: (1) reviewing the scale and selecting culturally appropriate domains for translation to standard Arabic; (2) conducting cognitive interviews with 30 11-17-year-old adolescent girls in Lebanon; (3) administering the scale to 339 refugee adolescent girls who participated in an early marriage intervention; and (4) conducting confirmatory factor analysis (CFA) on the data to assess the scale's psychometric properties. RESULTS: The original model for the 13-item, four-domain adapted scale demonstrated poor fit in CFA. After iteratively removing two items, scale properties were improved, albeit were not optimal. The validity and reliability results for the self-efficacy domain were acceptable. Cognitive interview data revealed that Arab adolescent girls understood self-efficacy in relational terms, recognizing that autonomous decision-making is not necessarily favored but is influenced by parents and family. CONCLUSIONS: This study presents an effort to customize an SRE scale for use in studies on the health of adolescent girls in an Arab cultural context. Findings from cognitive interviews highlight the importance of taking into consideration relationality in adolescent sexual and reproductive decision-making. The self-efficacy domain in the adapted scale demonstrates acceptable psychometric properties and is recommended for use in health studies to capture SRE.

Factorial validation of the children's eating behavior questionnaire and the association between the eating behaviors assessed and BMI Z score in Chinese preschoolers aged 2-5 years.

OBJECTIVE: This study aimed to evaluate the validity and reliability of the Children's Eating Behavior Questionnaire (CEBQ) among Chinese preschool children aged 2-5 years. Additionally, we investigated the associations between eating behaviors assessed by the CEBQ and body mass index (BMI). METHODS: A cross-sectional study was conducted with a sample of Chinese preschool children aged 2 to 5 years (n = 11,780). The CEBQ was employed to assess participants' eating behaviors, and factor analysis of the CEBQ was conducted; sex and age differences in eating behaviors were examined. Correlations between children's BMI z scores and eating behaviors were analyzed via linear regression analysis controlling for age; sex; ethnicity; maternal age, education level, ethnicity and BMI; paternal age, education level, ethnicity and BMI. RESULTS: The factor analysis confirmed the eight-factor structure of the CEBQ, which explained 67.57% of the total variance. Two items were excluded owing to low factor loadings. The subscales showed satisfactory internal reliability (Cronbach's alpha range: 0.76-0.90). Significant sex and age differences were observed for several CEBQ subscales, and BMI z scores were found to be associated with various eating behavior subscales. CONCLUSIONS: This study's findings support the validity and reliability of the CEBQ for assessing eating behaviors among Chinese preschool children, and children's eating behaviors might be affected by age and sex. Furthermore, BMI was found to be associated with specific eating behaviors. Understanding these associations can inform interventions that promote healthy eating habits in this population.

Psychometric properties of the Turkish version of Staff Attitude to Coercion Scale.

BACKGROUND: The aim of this study was to provide the Turkish version of the Staff Attitude to Coercion Scale (SACS) and to determine its psychometric properties. METHODS: This is a descriptive and correlation design. The sample of this study consisted of 100 psychiatric staff members. The validity and reliability of the scale were assessed through translation procedures, content validity analysis, and confirmatory factor analysis (CFA). Reliability was further evaluated using Cronbach's alpha and item-total score correlations. RESULTS: The content validity index was found to be 0.93. The scale has a three-factor structure and the Cronbach's alpha values of the subscales are 0.70 for offence, 0.87 for safety and 0.74 for treatment, respectively. The Cronbach alpha reliability coefficient of the total scale was found to be 0.86. CONCLUSION: The Turkish version of the SACS showed good reliability and validity, and confirmatory factor analysis revealed the same factor structure with three factors as in the original SACS.

Validation and measurement invariance of the Chinese version of the academic self-efficacy scale for university students.

Objectives: The objective of this study was to examine the psychometric properties of the Chinese version of the Academic Self-Efficacy Scale (ASES-C) and confirm its measurement invariance across gender identities. Methods: In this study, 502 university students (29.68% male, 70.32% female) with a mean age of 19.93 years (SD = 1.64) voluntarily participated. The Academic Self-Efficacy Scale (ASE) was utilized as a unidimensional measure of students' learning efficacy. The English version of ASES was translated into Chinese using a forward-backward translation procedure. Confirmatory factor analysis (CFA) and invariance testing were conducted with the single-factor model of ASES. Composite reliability (CR) and internal consistency were calculated based on Cronbach's alpha. Results: Upon re-specification of the model, CFA results for the hypothesized single-factor model with eight items indicated an acceptable fit (CFI = 0.959, TLI = 0.943, SRMR = 0.036, RMSEA = 0.065). Cronbach's alpha and CR values were 0.785 and 0.880, respectively. Multi-group CFA results demonstrated measurement equivalence for the Chinese version of ASES across gender identities. The findings supported the measurement invariance of ASES-C for both male and female participants. Conclusion: The ASES-C, consisting of one factor and eight items, is a reliable instrument for assessing Chinese university students' self-efficacy in learning. Furthermore, it is suitable for making meaningful comparisons across gender identities.

Validating the ChatGPT Usage Scale: psychometric properties and factor structures among postgraduate students.

BACKGROUND: The rapid adoption of ChatGPT in academic settings has raised concerns about its impact on learning, research, and academic integrity. This study aimed to develop and validate a comprehensive ChatGPT Usage Scale specifically tailored to postgraduate students, addressing the need for a psychometrically sound instrument to assess the multidimensional nature of ChatGPT usage in higher education. METHODS: A cross-sectional survey design was employed, involving 443 postgraduate students from two Egyptian universities. The initial 39-item scale underwent Exploratory Factor Analysis (EFA) using principal component analysis with Varimax rotation. Confirmatory Factor Analysis (CFA) was conducted to assess the model fit and psychometric properties of the final 15-item measure. Internal consistency reliability was evaluated using Cronbach's alpha and McDonald's omega. RESULTS: EFA revealed a three-factor structure explaining 49.186% of the total variance: Academic Writing Aid (20.438%), Academic Task Support (14.410%), and Reliance and Trust (14.338%). CFA confirmed the three-factor structure with acceptable fit indices (χ2(87) = 223.604, p < .001; CMIN/DF = 2.570; CFI = 0.917; TLI = 0.900; RMSEA = 0.060). All standardized factor loadings were statistically significant (p < .001), ranging from 0.434 to 0.728. The scale demonstrated good internal consistency (Cronbach's α = 0.848, McDonald's ω = 0.849) and composite reliability (CR = 0.855). The average variance extracted (AVE) was 0.664, supporting convergent validity. CONCLUSIONS: The validated ChatGPT Usage Scale provides a reliable and valid instrument for assessing postgraduate students' engagement with ChatGPT across multiple dimensions. This tool offers valuable insights into AI-assisted academic practices, enabling more nuanced investigations into the effects of ChatGPT on postgraduate education.
