This research aimed to investigate the validity and reliability of the moral intelligence scale of adolescents. The research was a descriptive survey. The statistical population was the first and second high school students of Isfahan province in 2024-2023. Based on the multi-stage cluster sampling method, 400 students were selected in the first stage and 900 students were selected in the second stage of the research. The data were analyzed using exploratory and confirmatory factor analysis, the reliability of the scale using Cronbach's alpha coefficient and its halving coefficient, and its validity using the convergence method and dependent on the criterion with the moral intelligence questionnaire of Abadian and Rabat Milli) MIQAR  ((2020). Each of the confirmatory factor analysis indices of the mentioned scale, including RMSEAI, PCFI, TLI, and CFI, had a suitable value. The alpha coefficient and the halving coefficient of the whole scale were also 0.96 and 0.93. The results of exploratory factor analysis led to the extraction of 7 factors (respect, responsibility, conscience, kindness, self-control, honesty, and forgiveness). Factor loadings of all components were higher than 0.4 and statistically significant (P<0.001). Criterion-dependent validity with the ethical H. scale was reported as 0.52 and significant (P<0.001). Due to the favorable state of validity and reliability, the scale of the moral intelligence of adolescents can be used as a valid and useful tool to check and measure the moral intelligence of adolescents.

The psychometric properties of the Persian version of the cyberbullying perpetration questionnaire were assessed in this study, which included reliability, validity, confirmatory factorial analysis, and gender differences in youth. This is a correlational research design that adheres to the common principles and techniques of psychometrics. It is an applied survey study that was conducted in 2022 and is based on a test construction methodology. 474 participants were selected from the statistical population, which consisted of young individuals aged 18 to 35 residing in Tehran and Shiraz, using convenience sampling. The cyberbullying Perpetration Questionnaire (CPQ) was translated in four stages. Using Cronbach’s alpha, Pearson correlation coefficient, confirmatory factorial analysis, and independent-samples t-tests at a significance level of 0.05, the collected data were analyzed in SPSS and AMOS software version 26. A one-factor model with fit indexes that were favorable (X2/df= 2.613, GFI= 0.953, IFI= 0.950, CFI= 0.949, PCLOSE= 0.109, RMSEA= 0.058) was supported by the confirmatory factorial analysis. Cronbach’s alpha coefficient of the cyberbullying Perpetration Questionnaire was 0.85, and test-retest reliability was 0.67. The perpetration of cyberbullying was significantly different between males and females (t=3.91, p<0.001). The cyberbullying Perpetration Questionnaire exhibited favorable psychometric properties for the purpose of assessing the perpetration of cyberbullying in young individuals.

The purpose of this research was to investigate the psychometric properties of the academic boredom scale and its relationship with academic motivation in students. The present research method was descriptive, validation type. The statistical population of research was male students of the second secondary level in District 5 of Tehran, in 1401-1402. A sample of 396 people was selected from this population by a two-stage cluster method. Participants completed the Academic Boredom Scale (ABS) (Pekrun et al., 2002) and the Academic Motivation Questionnaire (AMQ) (Lapper et al., 2005). Data were analyzed by confirmatory factor analysis (CFA), Cronbach's alpha, and Pearson's correlation coefficients. The results of the confirmatory factor analysis showed that the academic boredom scale has 22 items and two components classroom boredom and learning-related boredom. The fit indices of the confirmatory factor analysis confirmed the appropriate fit of the model. There was a significant negative relationship between the academic boredom scale and academic motivation (p<0.01). Cronbach's alpha coefficients for the factors of classroom boredom and learning boredom related to learning and the whole scale were obtained as 0.86, 0.88, and 0.93, respectively. Therefore, the Persian version of the academic boredom scale has favorable psychometric properties among Iranian students and can be used.

The current study aims to validate and explore the psychometric properties of the Japanese version of the Stimulant Relapse Risk Scale (SRRS). A total of 150 prisoners in Chenaran who were addicted to substances, were randomly chosen to complete two scales: The Stimulant Relapse Risk Scale's Japanese version (SRRS) and the Post-Detoxification Craving and Temptation Scale (PDCTS). An exploratory factor analysis indicated a five-factor structure, accounting for 77.54 percent of the variance. The second-order confirmatory factor analysis corroborated a satisfactory model fit. The Cronbach's alpha values registered at 0.94 for the entire scale, with subscale figures ranging from 0.92 to 0.95. Both convergent and divergent construct validity received positive evaluations. Overall, the SRRS exhibits a multifaceted structure and stands as a robust and valid tool for assessing relapse risk among substance users, offering significant implications for health and medical service provision.

The purpose of the present study was to investigate the validation and psychometric properties of We-ness questionnaire. The method of the research is descriptive and of the type of psychometric studies. The statistical population of the present study included all married people in Sistan and Baluchistan province, and 314 people were selected from this population by available sampling method. The tools for collecting information were our questionnaire (Topcu-Uzer et al., 2021), Revised Dyadic Adjustment Scale (Busby et al., 1995) and Marital Burnout questionnaire (Pines, 1996). Confirmatory factor analysis, content validity, convergent and divergent validity were used to check the validity of the questionnaire. The results of the research showed that the of the confirmatory factor analysis confirmed the suitability of the model and the structure of the internal relationships of the items. Cronbach's alpha coefficient and test-retest were used to check the reliability of the questionnaire, the results showed that our questionnaire has good internal stability and reliability in the Iranian sample, respectively (0.95, 0.68). To examin the convergent validity, Revised Dyadic Adjustment Scale was used and to examine the divergent validity, Marital Burnout Questionnaire was used which the results showed that our questionnaire has good criterion validity (0.73, -0.59).

The purpose of this research was to investigate the psychometric properties of the attributed traits scale specific to the situation in the conflicts of Iranian couples. The statistical population was married students of Tehran universities in 2023, of which 249 married students were selected based on available sampling.  The research tools were the situation-specific attribute scale in couple conflicts (CSCS; Backer-Fulghum et al., 2016), the marital happiness scale (MHS; Arzin et al., 1973), and the marital conflict questionnaire (MCQ; Sanai, 2000). To check the validity and reliability of the scale, convergent and divergent validity were used by calculating Pearson's correlation, Cronbach's alpha test, and binomial coefficient. The results showed that the scale has good reliability according to the calculated Cronbach's alpha (0.94) and dichotomization coefficient (0.93). Based on the high correlation between CSCS and marital happiness scale (r=-0.491) and marital conflicts questionnaire (r=0.532), it can be said that this scale has favorable convergent and divergent validity. To check the construct validity, confirmatory factor analysis was performed and the validity of the scale was confirmed. The correlation coefficient of the retest CSCS was calculated to be significant and equal to 0.994. These results show that the Persian version of CSCS has adequate validity and reliability, and as a result, couple therapists and psychotherapists can use it as a valid tool in working with Iranian couples.

The death of a loved one, especially when it happens tragically or prematurely, could rock the foundations of our hypothetical world and our relationship with God and the world (Neimeyer, 2019) and cause deep challenges (Neimeyer, Prigerson& Davies, 2002). Complicated spiritual grief is a crisis during bereavement that endangers the bereaved person’s sense of relationship with God or the religious community as they struggle to re-establish spiritual balance after the loss of a loved one (Holland, Burke, Neimeyer et al., 2014). As for complicated spiritual grief in Iran, there has been no scale to determine the psychometric properties thereof, nor has such a scale become normative in the country. The Inventory of Complicated Spiritual Grief (ICSG) is a 5-point scale that is used to measure post-grief meaning.  The ICSG has been used and validated by Neimeyer et al. (2014) and Holland Burke. However, the scale has not been investigated or psychometrically tested in Iranian society. The present research aims to investigate the psychometric properties of the Persian version of the ICSG in relation to the Iranian sample.
The research sample included 215 bereaved women in the Iranian city of Ardabil who were selected on an available basis. Then, they responded to the research tool. In the study, the ICSG (Holland, Burke and Neimeyer et al., 2014) and the Grief Experience Questionnaire (Barrett and Scott, 1989) were used. The statistical analysis was carried out using SPSS version 25 and AMOS version 24 software tools. The SPSS software was used for descriptive analysis, and the AMOS software was used for combined reliability (CR) and factor analysis.
 
The face, content and structure validity of the research showed that the ICSG has appropriate validity and reliability. The scale’s convergent validity was confirmed to be (AVE>0/50). The internal consistency reliability of the ICSG was assessed using composite reliability and Cronbach's alpha coefficient, and an alpha coefficient of 0.73-0.81 confirmed the reliability of the dimensions of the scale. In addition, the correlation results pertaining to the variables of the research showed that the ICSG has a significant correlation with the grief experience scale (p<0.01).
 
Overall, the findings of the research indicated that the 18-item Inventory of Complicated Spiritual Grief has strong internal consistency and convergent and incremental validity, and that the scale supports a two-factor model for measuring doubt in God and impairment of the person’s religious faith. Thus, the results of the present research showed that the ICSG has good validity and reliability for the Iranian sample.

Problem solving is one of the most important skills that all people, especially students, should learn in order to be able to use it when facing life's challenges and problems. In collaborative problem solving, the work is divided among the members of a group and they use their skills and knowledge to find a suitable solution. The current research was conducted with the aim of creating a standard tool to measure students' collaborative problem solving skills.The present research method was descriptive-correlation type. The statistical population of the study included 2500 Students of Farhangian University of Kerman in the academic year 1401-1400, of which 335 people were selected by random sampling based on Morgan's table. The form and content validity of the questionnaire was checked and confirmed by 5 experts in the field of psychology and its reliability using Cronbach's alpha method and confirmatory factor analysis. Data were analyzed using SPSS-26, LISREL and SmartPLS software.Cronbach's alpha coefficient of the questionnaire was calculated as 0.96. Factor loads of all subscales with relevant items were greater than 0.4, all of which were significant (p <0.001). The values of Cronbach's alpha and the combined reliability coefficient for the subscales were calculated to be more than 0.7, which confirms the internal and external reliability of the subscales. The results of the confirmatory factor analysis indicate a stronger relationship of the subscales of following participation rules, communicating with team members and explaining roles and team organization with collaborative problem solving. Therefore, it can be concluded that the skills of effective communication and teamwork among students are weak and the training of these skills should be included in the agenda of schools and universities.

The present study aimed to develop a native scale for measuring successful transition from university to work based on the researchers' database and to examine its psychometric properties.  The research employed a descriptive test-making approach. A sample of 436 final-semester undergraduate students from Isfahan University was selected using convenience sampling. Item analysis, content, face, simultaneous criterion validity, exploratory and confirmatory factor analysis were utilized to assess the factor structure of the scale, while Cronbach's alpha coefficient and retest reliability were examined for its reliability.  Exploratory factor analysis revealed a two-factor, 9-item structure with good fit indices. Confirmatory factor analysis confirmed the validity of the scale. Convergent validity was supported by significant positive correlations between the scale dimensions and the career employability scale and the career decision-making self-efficacy questionnaire. Divergent validity was confirmed through correlations between the scale dimensions and the career indecision questionnaire. Internal consistency, as measured by Cronbach's alpha coefficient, was high at 0.89, indicating good reliability. The retest coefficient, conducted with a two-week interval, was 0.86. These results supported the adequacy of the measurement scale for assessing successful transition from university to work.  The native successful transition scale presents a new and reliable tool for measuring students' successful transition from university to work.

Physical appearance perfectionism, which refers to the desire for a flawless physical appearance, was the focus of the study. The study aimed to examine the psychometric properties of the Persian version of the Physical Appearance Perfectionism Scale (PAPS) in a sample of Iranian adult women. A convenience sample of 324 adult women completed the PAPS, Tehran's multidimensional perfectionism (TMPS), and social appearance anxiety (SAAS) scales. Validity and reliability were checked using exploratory and confirmatory factor analysis, Pearson correlation, and internal consistency. The results confirmed the 2-factor structure of this scale, with both worry about imperfection and hope for perfection subscales showing a significant positive correlation with the scores of the Tehran Multidimensional Perfectionism Questionnaire and Social Appearance Anxiety Questionnaire. The Cronbach's alpha coefficient for the subscales was 0.90 and 0.89, respectively, and 0.90 for the total score. These findings suggest that the Physical Appearance Perfectionism Scale (PAPS) demonstrates good validity and reliability in Iranian adult women.
