The primary objective of the current paper was to assess the psychometric attributes of the Persian version of the Online Gambling Symptom Assessment Scale (P-OGSAS) within the Iranian population. The current study was conducted through a convenient sampling method between September and November 2021, involving 187 participants who had experienced online gambling at least once a month for the last 3 months. OGSAS was translated from English into Persian using the forward-backward translation method. Cronbach’s alpha coefficient and principal component analysis (PCA) were employed to evaluate the reliability and validity of the scale, respectively. Participants were administered a battery of assessments, including P-OGSAS, Persian Gambling Disorder Screening Questionnaire (GDSQ-P), Patient Health Questionnaire-9 Items (PHQ-9), and Generalized Anxiety Disorder Questionnaire (GADQ-7), to assess validity and reliability. The results showed that the 3-factor model of this scale provides the highest level of predictability. The 3-factor model accounts for 54.8% of the square load. With a Cronbach’s alpha coefficient of 0.807, P-OGSAS demonstrated satisfactory reliability. Finally, OGSAS has a significant correlation with other scales, and as a result, this scale has suitable convergent validity. P-OGSAS can adequately assess the symptoms and severity of online gambling. Therefore, clinicians could use this scale to evaluate the problems related to online gambling in the Iranian population.

Suicide represents a significant global health issue, shaped by a complex interplay of psychological, cultural, and economic factors. Key objectives in suicide prevention programs include reducing the stigma associated with suicide and enhancing suicide literacy.

The purpose of this study is to evaluate the psychometric properties of the Persian short forms of the Literacy of Suicide Scale and the Stigma of Suicide Scale (LOSS-SF and SOSS-SF).

This cross-sectional study utilized an online survey to gather data from 240 individuals in the general population. The scales were translated from English to Persian and then back-translated into English by professional translators, with the translation quality confirmed by an independent review team. The scales’ validity, reliability, and factor structure were thoroughly analyzed.

The scales’ internal consistency was determined using Cronbach’s alpha, with LOSS-SF scoring 0.76 and SOSS-SF scoring 0.79. The intraclass correlation coefficients for LOSS-SF and SOSS-SF were 0.81 and 0.75, respectively. Confirmatory factor analysis affirmed the structure of both scales.

The findings suggest that LOSS-SF and SOSS-SF possess appropriate psychometric properties for the Iranian context, enabling Persian-speaking professionals to use these tools for assessing key aspects of suicide.

The purpose of this study is to investigating the psychometric properties of the Iranian-Islamic spiritual well-being questionnaire, which envolves 22 adopted with Iranian cultural context.

The present study was descriptive-analytical. After designing the questions according to the Iranian-Islamic culture based on the literature review, the content validity was examined with the participation of experts (5 people with PH.D in psychology) and the CVI and CVR indices were used to check the quantitative content validity. To check the face validity, 10 people with the age range of 18 to 60 years were used as a sample. Also, exploratory and confirmatory factor analysis was used to check construct validity and Cronbach's alpha coefficient, test-retest coefficient, Spearman-Brown coefficient and Guttman split-half coefficient were used to check reliability. In the phase of examining the construct validity and reliability of the questionnaire, 400 adults aged 18 to 60 years were selected as a sample from Mashhad city in 2021 by available sampling method, and a test was conducted from them.

The CVR was obtained for 5 experts more than 0.99 and also CVI for 22 terms of the questionnaire was obtained from 0.79 and above, which is in the desired range. The exploratory factor analysis identified six factors, and these six factors together explained 77.25% of the total variance. The results obtained from the confirmatory factor analysis supported the proposed model. The Cronbach’s alpha coefficient of Iranian-Islamic spiritual well-being questionnaire and its factors was obtained from 0.77 to 0.91. In the split-half method, Spearman-Brown and Guttman correlation coefficients were 0.88 and 0.87, respectively. The test-retest reliability coefficients of the total score of the questionnaire and subscales were between 0.78 and 0.83.

Finally, based on the findings of this research, it can be concluded that the Iranian-Islamic spiritual well-being questionnaire has favorable psychometric properties.

Complaints of the arm, neck, and shoulder (CANS) in the workplace are becoming more prevalent among employees. The Maastricht Upper Extremity Questionnaire (MUEQ) validates upper extremity complaints in 7 domains—including workstation, body posture, break time, job control, job demands, work environment, and social support. The aim of the present study was to translate, adapt, and validate the Persian Version of MUEQ among Iranian office workers.   

The psychometric evaluation of the Persian version of the MUEQ employed a comprehensive methodological approach comprising face and content validity assessments, confirmatory factor analysis (CFA), and Cronbach's alpha. A panel of 10 experts assessed the face and content validity of the instrument. In the second phase, through a cross-sectional study, the validity and reliability of the questionnaire were measured by CFA and Cronbach’s alpha in a sample of 420 people from the target population in Tehran, Iran.   

The mean age of the participants was 41.40 ± 7.80 years. Examination of upper limb complaints showed that neck pain was the most common complaint among office workers, with a prevalence of 65%. The CFA results confirmed the questionnaire's structure, with 59 items grouped into 7 subscales, and with fit indices—comparative fit index, 0. 87; root mean square error of approximation, 0.08; goodness of fit index, 0.9. The questionnaire demonstrated strong internal consistency, as all items exhibited Cronbach's alpha values of ≥0.9.   

The psychometric evaluation of the Persian version of the MUEQ showed that it is a valid and reliable tool for evaluating psychosocial factors in the work environment. Identifying psychosocial factors influential in musculoskeletal problems will lead to better planning to change behavior and design constructive interventions to improve behavior. By addressing psychosocial determinants of musculoskeletal issues at both the individual and organizational levels, we can enhance employees' awareness, self-efficacy, and ability to manage their musculoskeletal health and make informed decisions about their well-being.

The rapid growth of information technology has created opportunities for online learning.

The aim of this study was to investigate the psychometric properties of the Persian version of the Online Learning Readiness Scale (OLRS) and assess the readiness of health care providers in this regard.

This cross-sectional study was conducted in 2022 among 181 health care providers in Kerman, selected through multi-stage sampling. The data collection tool included a questionnaire with demographic information and the Persian version of OLRS, comprising 18 questions across 5 subscales: computer/internet self-efficacy, self-directed learning, learner control, learning motivation, and online communication self-efficacy. Data were analyzed using Pearson correlation, independent t</em>-test, and analysis of variance (ANOVA) in SPSS v. 26, as well as LISREL v. 8.8 software.

Cronbach's alpha coefficient for subscales ranged from 0.74 to 0.93, with factor loadings of items ranging from 0.54 to 0.96. Goodness-of-fit indicators met acceptable standards. The mean scores for all subscales exceeded the average (2.5). Health care providers in rural areas had higher mean scores in the self-directed learning (P=0.04), learning control (P=0.02), and learning motivation (P=0.001) subscales. Men scored higher in the self-directed learning (P=0.01) and learning motivation (P=0.04) subscales.

The Persian version of OLRS demonstrates satisfactory psychometric properties and can be used to assess the readiness of learners for online learning. When planning such training, it is crucial to consider factors related to learners' readiness, including demographic and occupational characteristics.

Aging is often defined as a reduction in productivity, ability, and independence. A crucial step in combating ageism is to thoroughly categorize the scale of ageism through appropriate psychometric methods. Therefore,

This study aimed to evaluate the psychometric properties of the ageism scale of Vefikuluçay Yilmaz and Terzioglu.

This descriptive and psychometric study was conducted on 230 (13 - 63) individuals in the fall of 2021 in Tehran, Iran, who were selected by convenient method. Construct validity was performed by exploratory and confirmatory factor analysis after the face and content validity. The tool reliability was also examined by the internal consistency and reliability method.

Content validity indicators for the whole questionnaire were content validity ratio (CVR) = 0.72 and content validity index (CVI) = 0.64. The KMO test rate was 0.835, and Bartlett’s test was also significant (df = 253, P < 0.001). Four factors were extracted from the exploratory and confirmatory factor analysis, including "dignity of older adults in the family," "restriction of older adults," "social presence," and "characteristics of older adults," which explained 30.57% of the total variance of ageism. The tool’s reliability was obtained using Cronbach’s alpha coefficient of 0.72 and intra-cluster correlation coefficient (ICC) = 0.94. In addition, the measurement model in confirmatory factor analysis had a moderate fit (root-mean-square error of approximation (RMSEA) = 0.081, comparative fit index (CFI) = 0.610, goodness of fit (GFI) = 0.850).

The Persian version of the ageism scale of Vefikuluçay Yilmaz and Terzioglu had acceptable validity and reliability in the Iranian population, and it is a tool for measuring people’s attitudes toward the phenomenon of aging.

Given the prevalence of somatic symptoms disorder among Iranians, the aim of this research is to evaluate and verify the psychometric characteristics of Takata and Sakata psychosomatic complaints scale among psychosomatic patients.

In this study 360 people who referred to the psychosomatics department of Taleghani Hospital in Tehran in 2022, as well as the patients referred by the physicians, psychiatrists and psychologists of medical centers were selected through convenience sampling method. Internal consistency method (Cronbach's alpha) was used to determine the reliability of the questionnaire. Also, exploratory factor analysis and confirmatory factor analysis were used to determine the factor structure. To ensure convergent validity, Goldberg general health scale (GHQ-28) was used and SPSS and Lisrel software were applied for analyzing data.

The results of the Cronbach's alpha indicated the appropriate internal consistency of the whole questionnaire and its components. Cronbach's alpha for the whole questionnaire was 0.957. In the exploratory factor analysis, a "hyper stimulation" factor was extracted. According to confirmatory factor analysis, the goodness of fit indicators of proposed model were confirmed (Chi-Square/df: 1.297, RMSEA: 0.029, SRMR: 0.031, CFI: 0.976, IFI: 0.976) and all paths were significant. Regarding the convergent validity, somatic symptoms component, anxiety, dysfunction in social action and function, and depression have a direct and significant relationship with psychosomatic problems.

The Persianversion of the takata and sakata psychosomatic complaints scale, is a reliable and valid tool for assessing of the severity of psychosomatic symptoms in Iranian psychosomatic patients.

This study aimed to determine the psychometric properties of Persian version of Irritable Bowel Syndrome-Behavioral Responses Questionnaire (IBS-BRQ).

In addition to somatic symptoms and complaints, patients with irritable bowel syndrome have specific dysfunctional behaviors that lead to disease persistence and functional disturbance.

Participants included 170 patients with irritable bowel syndrome, who were diagnosed based on ROM-IV criteria and selected from patients referring to the Gastrointestinal Disorders Clinic, as well as 100 persons from the general populationin Isfahan in 2020. Both groups completed the 26-item Irritable Bowel Syndrome-Behavioral Responses Questionnaire (IBS-BRQ). Also, questionnaires including the Irritable Bowel Syndrome Symptom Severity Scale (IBS-SSS), Irritable Bowel Syndrome-Quality of Life IBS-QOL, Illness Perception Questionnaire (IPQ-R), Irritable Bowel Syndrome-Patient Satisfaction (IBS-SAT), Hope Scale, Interpersonal Forgiveness Inventory (IFI), and Dysfunctional Attitude Scale-26-item (DAS-26) were completed to determine the validity of IBS-BRQ. Tests of internal consistency, principal components analyses (PCAs), differentiation analysis, and correlation were used to determine its reliability, along with criterion and construct validity.

IBS-BRQ was valid and reliable in both groups with a high degree of internal consistency. Cronbach's alpha was obtained in the sample of patients with IBS and the total sample of participants 0.87 and 0.95 respectively. This scale differentiated significantly between IBS patients and non-patients (p<.001). The criterion validity was high as evidenced by a high correlation with DAS-26 (r=0.53, p<0.001), IBS-QOL (r=0.76, p<0.001), IBS-SSS(r=0.44, p<0.001), IPQ-R(r=0.56, p<0.001), and reverse correlation with IFI (r=-0.031, p<0.001), IBS-SAT(r=-0.23, p<0.001), and HOPE (r=-0.49, p<0.001).

The Persian version of the IBS-BRQ proved to be a well-defined behavioral response measure in IBS patients with high validity and reliability, making it a suitable measure to be used in future IBS clinical research in Iran.

A short, valid, and reliable instrument is required for the easy assessment of health literacy in online surveys.

In this study, we investigated the validity and reliability of the Persian version of the 8-item Health Literacy Questionnaire as a brief online survey tool in 18-65-year-old Iranians.

This was a cross-sectional study undertaken in thirty-one provinces of Iran. A total of 2374 Iranian people with age 18 - 65 years participated in this study. To ensure the quality of English-to-Persian translation, the process of forward-backward translation was conducted. The scale’s factor structure was assessed using a series of exploratory factor analyses (EFA) and confirmatory factor analyses (CFA). In order to assess reliability, Cronbach’s alpha estimation, test-retest reliability, and Spearman correlation coefficients were applied.

Most of the participants were male (1610, 67.8%), married (1610, 67.8%), and 31 - 59 years old (1672, 70.4%). Cronbach’s alpha coefficients for the factors of finding & evaluating, understanding, decision making, interaction, and the questionnaire as a whole were 0.76, 0.46, 0.75, 0.82, and 0.59, respectively. Test-retest correlation coefficients for these factors and the questionnaire as a whole were 0.85, 0.94, 0.75, 0.82, and 0.86, respectively. Based on CFA, the four-factor structure of the 8-item health literacy (HL) fitted the data well.

The validity and reliability of the online version of the Persian 8-item Health Literacy Questionnaire to measure the HL of the public were approved. This short online tool can be helpful for future online survey studies on the health literacy of Persianlanguage populations at a large scale.

Some accurate tools exist to assess fear-avoidance behavior, such as the Tampa scale for kinesiophobia (TSK) in individuals with musculoskeletal problems. The current research aims to compare the psychometric characteristics of the original 17-items TSK questionnaire and its 11-item brief version in chronic non-specific low-back pain (CNSLBP).

In this test development study, 295 patients with CNSLBP referred to the physiotherapy clinic of Milad Hospital in Tehran city, Iran were evaluated. Confirmatory factor analysis (CFA) and α Cronbach was conducted to assess the validity and reliability of the original and brief version of the TSK, respectively. For goodness-of-fit, the Χ2/df, root mean square error of approximation (RMSEA), goodness-of-fit index (GFI), and comparative fit index (CFI) indices were used.

Internal consistency specified by Cronbach’s α was 0.949 for the original version of the questionnaire and 0.927 for the brief one. Based on the CFA findings, the goodness-of-fit indices for the brief version were GFI=0.921, RMSEA=0.078 (90% confidence interval (CI), 0.062%-0.094%), comparative fit index (CFI)=0.981, and Χ2/df=2.791. These indices for the original one were 0.882, 0.066 (90% CI, 0.055%-0.076%), 0.983, and 2.270, respectively. A significant correlation was found between these two versions (P<0.001). These findings confirm the adequacy of the brief version of the TSK.

The brief version of TSK can be considered a reliable and valid tool to evaluate somatic focus and activity avoidance in patients with CNSLBP.

The stigma of mental disorders is a common phenomenon, that barricades seeking medical help. Stigma includes a negative attitude toward a person that occurs due to a distinctive feature, such as race, sexual orientation, or mental disorder. Regarding the negative consequences of the stigma in the course of the disorder and the life of people with mental illness, the aim of this study was to investigate the psychometric properties of the Iranian version of the stigma-9 questionnaire (STIG-9) in people with mental disorders.

The statistical population included all military personnel with mental disorders hospitalized in the 505 Psychiatric Hospital from October 2020 to January 2021. By convenience sampling method, 95 patients were selected. For data analysis, descriptive and inferential statistics using SPSS software, version 26, and for factor analysis, R Coding software version 3.6.3 and R package lavaan 0.7 were used.

The face validity was evaluated quantitatively using impact score and the content validity was evaluated quantitatively using content validity ratio (CVR) and content validity index (CVI) based on the opinion of 15 experts. All items were validated in terms of face and content validity. To evaluate the internal consistency, Cronbach’s α coefficient was calculated (α=0.86). Factor analysis was used to evaluate the construct validity. The results of factor analysis showed that the questionnaire had three factors.

The Stig-9 questionnaire is an appropriate instrument to evaluate perceived stigma in people with mental disorders in Iranian society.
