Background: No standard self-report instrument for withdrawal symptoms is available in Iran. Objectives: This study aimed to evaluate the psychometric properties of the Persian version of the 10-item Amphetamine Withdrawal questionnaire version 2 (AWQV2). Methods: A sample of 388 methamphetamine addicts (215 females and 173 males) referred to addiction recovery centers and psychiatric ward of Farabi Hospital in Kermanshah. A two-stage random sampling method was used. The reliability and internal consistency of the AWQV2 items were examined using Cronbach’s alpha and test-retest reliability, respectively, and the instrument validity of the AWQV2 was measured using construct validity and convergent validity. Results: The AWQV2 had a Cronbach’s alpha of 0.72. Factor analysis using the main component analysis with a varimax rotation introduced three factors of hyperarousal, anxiety, and reversed vegetative symptoms. These factors explained 0.58 of the total variance. The coefficient of test-retest reliability at a 2-week interval was equal to 0.77. The convergent validity of the AWQV2 was examined by simultaneously administering the Advanced Warning of Relapse (AWARE) questionnaire to 40 subjects, with a correlation coefficient of 0.81. Conclusions: Based on the results, the AWQV2 has very good psychometric properties and may be used in research and therapeutic interventions.

Early Trauma

AbstractIntroductionTraumatic experience in childhood or adolescence has a significant impact on the development of chronic mental and physical conditions in adulthood. Thus, it is very important for health professionals, especially primary care physicians to have an inventory in order to detect early trauma for planning appropriate treatment, such as the Early Trauma Inventory (ETI). The aim of this paper is to test the psychometric properties of the Slovenian translation of the short, self-rated version (ETISR-SF), and to further validate the instrument.MethodsThe research was done in two parts – qualitative and quantitative. In the qualitative part, a questionnaire was translated and culturally adapted using the Delphi method. For the quantitative part, 51 patients with substance use disorders hospitalized at the Centre for the Treatment of Drug Addictions were recruited, along with 133 controls. The psychometric properties of the questionnaire were checked. Internal consistency was calculated using Cronbach’s alpha, test-retest reliability was examined graphically using a Bland-Altman plot. Discriminant validity between groups was gauged using the independent samples t-test.ResultsConsensus in the Delphi study was reached in the second round. Cronbach’s alpha varied between 0.60 - 0.85. Of the four domains, physical abuse had the lowest Cronbach’s alpha. The test-retest reliability is high for all domains, with correlation coefficients ranging from 0.82 to 0.96. The non-clinical sample differed significantly from the clinical sample.ConclusionThe Slovenian translation of ETISR-SF is a satisfactory instrument for the evaluation of trauma before the age of 18.

Objective: The Weiss Functional Impairment Rating Scale–Self-Report Form (WFIRS-S) was developed as a measure of functional impairment in adolescents and adults with ADHD. This study reports the psychometric properties of the Persian version of the WFIRS-S in a sample of normal Iranian adolescents. Method: Internal consistency and factor structure of the WFIRS-S were tested on a sample of 386 students (Grades 7-12). The test-retest reliability and the convergent validity of the WFIRS-S were evaluated by using two different subsamples including 50 and 100 students, respectively. Results: The Cronbach’s alpha values were between .72 and .94 for the WFIRS-S subdomains and total scale. The test-retest reliability was .80 for the total scale. The WFIRS-S subdomains had moderate to high significant correlations with the Pediatric Quality of Life total scale. Conclusion: The Persian version of the WFIRS-S has acceptable psychometric properties and could be used as a functional impairment assessment for adolescents.

Abstract Background Patient enablement is a core tenet of patient-centred and holistic primary care. The Patient Enablement Instrument (PEI) is a transitional measure limited in its ability to measure changes over time. A modified version, PEI-2, has been developed to measure enablement at a given time-point without comparison to a recalled baseline. Objective To assess the validity, reliability, sensitivity and responsiveness of PEI-2. Methods PEI-2 was modified from the Chinese PEI to assess enablement over 4 weeks in a prospective cohort study nested within a community support programme [Trekkers Family Enhancement Scheme (TFES)] in Hong Kong. Construct validity was assessed by factor analysis and convergent validity by Spearman’s correlations with health-related quality of life and depressive symptoms. Internal reliability was assessed using Cronbach’s alpha. Test–retest reliability was assessed by intraclass correlation (ICC), responsiveness by 12–24-month change in PEI-2 score and sensitivity by differences in change of PEI-2 score between TFES participants and a control group. Results PEI-2 demonstrated construct validity with all items loading on one factor (factor loadings >0.7). Convergent validity was confirmed by significant correlations with 12-item Short Form Questionnaire, version 2 (r = 0.1089–0.1919) and Patient Health Questionnaire-9 (r = −0.2030). Internal reliability was high (Cronbach’s alpha = 0.9095) and test–retest reliability moderate (ICC = 0.520, P = 0.506). Significant improvements in PEI-2 scores among the TFES group suggested good responsiveness (P < 0.001). The difference in change of PEI-2 scores between TFES and control was significant (P = 0.008), indicating good sensitivity. Conclusions This study supports the validity, reliability, sensitivity and responsiveness of PEI-2 in measuring changes in enablement, making it a promising tool for evaluating enablement in cohort and intervention studies.

Abstract Background Chronic conditions impose a major impact on quality of life and on healthcare. The Assessment of Burden of Chronic Conditions (ABCC-)tool was developed to improve experienced quality of care and quality of life by facilitating shared decision-making and self-management. It assesses the experienced burden of one or multiple conditions, and visualises and integrates the burden in daily care. However, its scale’s validity and reliability are yet unknown. The aim of this study is to evaluate whether the ABCC-scale is valid and reliable in people with Chronic Obstructive Pulmonary Disease (COPD), asthma, or Type 2 Diabetes Mellitus (T2DM). Methods The Saint George Respiratory Questionnaire (SGRQ), the Standardized Asthma Quality of Life Questionnaire (AQLQ-S), and the Audit of Diabetes Dependent Quality of Life Questionnaire (ADDQoL19) were compared to the ABCC-scale to assess convergent validity. Convergent validity was assumed when at least 75% of the postulated correlations were higher than 0.7, or between 0.3 and 0.7 for single-item subscales. To measure known-group validity, participants were categorized according to exacerbation status, depression, asthma control, insulin dependence, complications and obesity. The ABCC-scale was deemed internally consistency upon a Cronbach’s alpha ≥ 0.90 for the total scale, and ≥ 0.70 for subscales. Test-retest reliability was evaluated at a two-week interval. Results A total of 65, 62, and 60 people with COPD, asthma, T2DM respectively were included. The ABCC-scale correlated, in accordance with hypotheses, with the SGRQ (75%), AQLQ-S (100%), and ADDQoL19 (75%). Differentiation of known-groups based on the ABCC-scale was possible for all specified groups. The total score and subscores of the ABCC-scale were internally consistent with a Cronbach’s alpha of 0.90, 0.92, and 0.91 for the total score for people with COPD, asthma, and T2DM respectively. The ABCC-scale had a good test-retest reliability with an Intraclass Correlation Coefficient of 0.95, 0.93, and 0.95 for people with COPD, asthma and T2DM respectively. Conclusions The ABCC-scale is a valid and reliable questionnaire that can be used within the ABCC-tool for people with COPD, asthma or T2DM. Future research should indicate whether this also applies to people with multimorbidity, and what the effects and experiences are upon clinical use.

Abstract This study was designed to adapt the Breast Cancer and Lymphedema Symptoms Experience Index (BCLE-SEI) to the Spanish language (BCLE-SEI-Es) and to assess its psychometric properties in Spanish-speaking women diagnosed with breast cancer. 286 breast cancer survivors were recruited. Study measured demographic and medical data and the BCLE-SEI. Reliability was measured using Cronbach’s alpha and test-retest reliability (n = 29) after an interval of two weeks. A robust principal components analysis was conducted to explore the dimensions of each BCLE-SEI-Es subtest. Discriminant power of the BCLE-SEI was assessed through a non-parametric test evaluating score differences between non-lymphedema and lymphedema patients. A cut-off point was established via a ROC curve. Cronbach’s alpha: all scales had a value above 0.9. Test-retest reliability: Correlations between questionnaire administrations were above 0.7. The first and second subtests showed a good fit to a unidimensional and two-factor structure, respectively. Lymphedema patients score significantly higher in all BCLE-SEI scales (p < 0.001). A cut-off point was established to predict a possible lymphedema case. The BCLE-SEI-Es is a valid, reliable tool for assessing and identifying the presence of lymphedema among breast cancer survivors and assessing its impact on the physical, functional, psychological and emotional aspects.

Schema Questionnaire

La existencia de esquemas maladaptativos tempranos (EMTs) es el concepto central de Schema Therapy (ST). Varios estudios han demostrado que los EMS están involucrados en muchos trastornos psiquiátricos. El Young Schema Questionnaire es una medida de autoinforme desarrollada para evaluar los 18 EMTs y tiene versiones de forma larga (YSQ-L) y forma corta (YSQ-S). Actualmente se encuentra en su tercera versión (YSQ-S3). Hasta donde tenemos conocimiento, este es el primer estudio que tiene como objetivo validar el YSQ-S3 de acuerdo con la nueva organización propuesta de EMTs en cuatro dominios. Una muestra no clínica de 1372 estudiantes italianos participó en esta investigación. El análisis factorial confirmatorio (CFA) se realizó para examinar la estructura latente del YSQ-S3, incluidas las estructuras de primer y segundo orden. Se calcularon los coeficientes de correlación alfa e intraclase de Cronbach para evaluar la consistencia interna y la fiabilidad test-retest. Las correlaciones entre el YSQ-S3 y la ansiedad y los síntomas del estado de ánimo se calcularon para medir la validez de constructo. El alfa de Cronbach de casi todos los EMTs fue superior a 0.7, lo que indicó una buena confiabilidad interna, y la confiabilidad test-retest fue excelente. CFA apoya la nueva organización propuesta de EMS en cuatro dominios. Con respecto a la validez concurrente, cada esquema en el YSQ-S3 estaba altamente correlacionado con la ansiedad y los síntomas del estado de ánimo. El nuevo modelo de cuatro dominios del YSQ-S3 ha demostrado que puede ser una herramienta útil y válida para los médicos e investigadores en la medición del autoinforme de los EMTs. The existence of early maladaptive schemas (EMS) is the core concept of Schema Therapy (ST). Several studies have demonstrated that EMSs are involved in many psychiatric disorders. The Young Schema Questionnaire is a self-report measure developed to assess the 18 EMSs and has long form (YSQ-L) and short form (YSQ-S) versions. It is currently in its third version (YSQ-S3). To the best of our knowledge, this is the first study that aims to validate the YSQ-S3 according to the new proposed organization of EMSs into four domains. A non clinical sample of 1372 Italian population was involved in this research. Confirmatory Factor Analysis (CFA) was conducted to examine the latent structure of the YSQ-S3, including both first- and second-order structures. Cronbach’s alpha and intra-class correlation coefficients were calculated to evaluate internal consistency and test-retest reliability. Correlations between the YSQ-S3 and anxiety and mood symptoms were calculated to measure construct validity. Cronbach’s alpha of almost all EMSs were higher than 0.7, which indicated good internal reliability, and test-retest reliability was excellent. CFA supports the new proposed organization of EMSs into four domains. Regarding concurrent validity, each schema in the YSQ-S3 was highly correlated with anxiety and mood symptoms. The new four-domains model of the YSQ-S3 has demonstrated that it can be a useful and valid tool for clinicians and researchers in the self-report measurement of EMSs.

OBJECTIVES Translate and culturally adapt the short version of Copenhagen Psychosocial Questionnaire II (COPSOQ II) into Brazilian Portuguese (COPSOQ II-Br) and evaluate its psychometric properties. METHODS Translation and cultural adaptation followed the standardized guidelines. Structural validity was assessed using exploratory factorial analysis. Test-retest reliability was evaluated by intraclass correlation coefficient (ICC3,1) and internal consistency by Cronbach’s alpha. Floor and ceiling effect was considered acceptable if less than 15% of participants reported the lowest or highest scores. Measurement error was assessed by standard error of measurement (SEM), while construct validity was tested by correlating the COPSOQ II-Br, the Job Content Questionnaire and the Nordic Musculoskeletal Questionnaire. RESULTS The study evaluated a total of 211 civil servants and service providers in the test and 157 in the retest. After cross-cultural adaptation, the COPSOQ II-Br structure comprised seven domains and 11 dimensions. Most dimensions showed acceptable floor and ceiling effects, excepting “Work family conflicts” (floor effect of 26.1%), and “Meaning and commitment” and “Job satisfaction,” with ceiling floor of 27.5% and 22.3%, respectively. Cronbach’s alpha values reached the recommended levels (varied between 0.70 and 0.87). Test-retest reliability indicated that all dimensions had ICC between 0.71 and 0.81. SEM ranged from 0.6 to 2.2 and the construct validity showed good results with the tested instruments (significant positive and negative correlations). CONCLUSIONS All psychometric properties of the short version COPSOQ II-Br are suitable for use in Brazil. The instrument is thus validated and can be used by occupational health and human resources professionals to evaluate psychosocial working conditions.

The present study aimed to evaluate the psychometric properties of the Persian version of CSS in the Iranian population.Methods: A total of 393 participants volunteered to cooperate in the present study via an online survey. They completed a collection of scales, including the CSS, COVID-19 Phobia Scale (C19P-S), and Brief Symptom Inventory (BSI). The CSS reliability was determined by calculating Cronbach alpha and test-retest reliability. The validity assessed by Pearson correlation among the CSS and its subscales with C19P-S and BSI. Exploratory Factor Analysis (EFA) and Confirmatory factor analysis (CFA) was used to evaluate the structure of CSS. All analysis assessed by SPSS-26 software.Results: Results showed that 45.3% of the participant’s age were in 18-25 years. Moreover, 72.8 % of the participants were female. Also, Cronbach’s alpha for all subscale was between0.83 to 0.92. The test-retest reliability coefficient of CSS was 0.87. The correlation between the CSS, BSI and C19P-S showed that CSS has suitable convergent validity. CFA and EFA showed that the 5-factor of CSS is the best model. Conclusion: To conclude, Persian version of CSS has suitable psychometric properties for utilizing in Iranian population.

The psychometric properties of a new scale, the Obsessive Compulsive Inventory (OCI; Foa, Kozak, Salkovskis, Coles, & Amir, 1998), were examined in a nonclinical student sample. The study was a partial replication of the original validation study by Foa et al. Test-retest reliability, internal consistency, and convergent validity were examined using a sample of 126 undergraduate psychology students. Statistical analyses (Pearson's r and Cronbach's alpha) indicated adequate test-retest reliability for the full scales and subscales (coefficients ranging from 0.69 to 0.88) and high internal consistency (all coefficients exceeding 0.7). Convergent validity with the Maudsley Obsessional Compulsive Inventory (MOCI; Hodgson & Rachman, 1977) was adequate for the full scales and for the Washing and Checking subscales (coefficients ranging from 0.61 to 0.75). The OCI is a useful supplement to existing self-report measures of obsessive-compulsive symptomatology.

Abstract Background The Michigan Hand Questionnaire (MHQ) is widely used to assess the hand/wrist conditions. We translated the original version into Thai (Thai MHQ) and evaluated its psychometric properties. Methods After receiving permission, the original MHQ was translated and cross-culturally adapted to Thai following standard guidelines. Two hundred and seventeen patients who had hand/wrist injuries or disorders were included in the study. Internal consistency was evaluated using Cronbach’s alpha. Test-retest reliability was analyzed using the intraclass correlation coefficient (ICC). Spearman’s rank correlation among the subscales of Thai MHQ, Thai DASH and Thai EQ-5D-5L and also confirmatory factor analysis (CFA) were used to explore construct validity. The standardized response mean (SRM) was used to evaluate the responsiveness of the Thai MHQ. Results All subscales showed an acceptable Cronbach’s alpha (0.79–0.98). The test-retest reliability of each subscale was good (ICC = 0.83–0.95). In related dimensions, strong correlation was demonstrated between the Activities of daily living subscale of the Thai MHQ and the Common activities subscale in the Thai DASH (r = 0.77, P < 0.0001). For unrelated dimensions, a weak correlation was found between the Aesthetics subscale in the Thai MHQ and the Mobility subscale in the Thai EQ-5D-5L (r = − 0.13, P = 0.05). The Thai MHQ had strong correlation with Thai DASH (r = − 0.79, P < 0.0001) and Thai EQ-5D-5L (r = 0.63, P < 0.0001). CFA showed that the 6-factor model demonstrated an acceptable fit to the data. The SRM of the Thai MHQ was 0.78, indicating relatively large responsiveness. The MIC of Thai MHQ using distribution methods (SEM) was 5.2. Conclusions The Thai MHQ provides adequate internal consistency in all subscales as well as good construct validity and reliability for Thai patients and a relatively large standardized response mean at 2 months after treatment.
