Abstract
The purpose of the present study was to investigate the validity and reliability of the Personal Responsibility Scale for Adolescents (Mergler & Shield, 2016). The statistical population consisted of all first and second year high school students in Firoozabad city who were studying in the year 1396-97. Participants were 300 high school students (111 girls and 189 boys) who were selected by cluster random sampling. This scale was preliminary study after the Persian translation and confirmation of the validity of the translation. The results of exploratory factor analysis indicated that there were two distinct factors of cognitive control / responsiveness and behavioral / emotional control which together explained 59.28% of the total variance. Model fit indices using confirmatory factor analysis for chi-square to freedom ratio of 1.67, comparative fit of 0.98, normalized fit of 0.95 and root mean square error of estimation error of 0.04 indicate fit. The model with the data was desirable. Cronbach's alpha coefficient for cognitive / responsive control was 0.93 and for behavioral / emotional control was 0.70. In conclusion, this tool seems to have two factors to measure the personal responsibility of first- and second-grade students in adolescence.

Abstract
The current research was conducted with the aim of validating the paradigm model of spouse selection of satisfied
couples in Tehran and was a descriptive-correlation study using confirmatory factor analysis and structural
equation modeling. In this research, sampling was done with a purposeful method, and 6 clinics were selected
from among the counseling clinics of multiple areas of Tehran city, representing different social and economic
bases. 300 people who met the entry and exit criteria and scored a high score in the screening tool were selected
as a sample. The research tools included the researcher-made questionnaire of the model-partner selection of
satisfied couples and the marital satisfaction questionnaire of Enrich (1998). Confirmatory factor analysis with
AMOS24 software was used to check the validity of the proposed model. Also, in order to examine the paradigm
model of the research, the structural equation approach based on partial least squares method with PLS-3
software was used. Examining the fit indices of the proposed model showed that the model has a good fit and the
factor loading of all the main and subcategories of the research model was greater than 0.4. Also, the results
showed that the validity and reliability of the scales of the proposed model are suitable. The results of direct and
indirect effects of the research model were also examined. The findings of this research indicated that in Iranian
culture, several factors at different levels affect the process of choosing a satisfactory spouse, and it is necessary
for counselors and couple therapists to formulate their interventions based on this.

Abstract
This study aimed to translate and validate the Persian version of the Multidimensional Wellbeing in Youth Scale (MWYS) for a sample of Iranian adolescents. This descriptive-evaluative study translated and validated the Farsi version of the Multidimensional Wellbeing in Youth Scale (MWYS) in a sample of Iranian adolescents. The study population consisted of all adolescents aged 12-18 years living in Qom, Iran, in 2022-23, of whom 300 adolescents were selected as the sample through convenience sampling. To examine the test-retest reliability of MWYS, 50 participants were randomly selected to fill out this scale twice at an interval of two weeks. The Multidimensional Wellbeing in Youth Scale (MWYS, Green et al., 2023), the Satisfaction with Life Scale (SWLS, Diener et al., 1985), and the Perceived Stress Scale (PSS, Cohen et al., 1983) were used in this study. The obtained data were statistically analyzed in SPSS and AMOS. Results showed the favorable test-retest reliability (0.77) and internal consistency (0.73) of MWYS, according to Cronbach’s alpha. The confirmatory factor analysis (CFA) also demonstrated that the five-factor measurement model was well fitted to the data after removing items 13, 14, 18, 30, and 33 (RMSEA=0.04, CFI=0.91, X2/df=2.76). Also, the results showed that MWYS has favorable convergent and divergent validity. Since MWYS exhibited acceptable validity and reliability in a sample of Iranian adolescents, it is recommended to be used for measuring the well-being of Iranian adolescents.

Abstract
This study aimed to investigate the factor structure and gender invariance of the Interpersonal Needs Questionnaire (INQ-15) in university students. The research design was descriptive-correlational and, more specifically, validating the test. The statistical population of the research was formed by the students of Ferdowsi University of Mashhad in the fall semester of 2022-2023. Regarding the number of variables, for the first phase of the study, 236 students and in the second phase 292 students were selected using the multistage random sampling method. Data were collected using the Interpersonal Needs Questionnaire (INQ-15; Van Orden et al. 2012), Need to Belong scale (NTBS; Kelly, 1999), Young schema questionnaire (YSQ-SF; Waller et al., 2001), Depression, Anxiety, Stress Scale (DASS-21; Lovibond, & Lovibond, 1995), Kessler Psychological Distress Scale (K6; Kessler et al, 2000) and Beck Scale for Suicide Ideation (BSSI; Beck et al., 1979). The results of the exploratory factor analysis showed that the scale has a two-factor structure with an explained variance of 72.41% and demonstrated good confirmatory validity. The factor structure of the scale was invariant by gender. The Cronbach’s alpha and split-half coefficients were between 0.81 and 0.96. The positive correlation with Need to Belong, Isolation Schema, Depression, and Psychological Distress (P<0.01) implied the convergent validity of the questionnaire. Interpersonal needs could predict suicidal ideation (P<0.01). Overall, the Interpersonal Needs Questionnaire (INQ-15) demonstrated acceptable validity and reliability and can thus be dependably used in studies of interpersonal relationships among students.

Abstract
This study aimed to validate the Self-Critical Rumination Scale (SCRS) for a sample of Iranian university students. This descriptive-evaluative study translated and validated the Persian version of (SCRS) in a sample of Iranian students. A convenience sample of 307 students from the University of Tabriz was recruited for this study in 2023. To examine the test-retest reliability of SCRS, 50 participants were randomly selected to fill out this scale twice at an interval of two weeks. The Self-Critical Rumination Scale (SCRS), the Depression, Anxiety, and Stress Scale - 21 Items (DASS-21, Loviband & Loviband,1995), and the Short form of the self-compassion Scale (SCS-SF, Raes et al., 2011) were used in this study. According to the results of exploratory factor analysis (EFA), 1 factor was identified, which explains 55% of the total variance. The results of criterion validity showed that SCRS had a positive relationship with Depression, Anxiety, and Stress and a negative relationship with self-compassion (P<0.05); which respectively shows the convergent and divergent validity of this tool. According to Cronbach's alpha, results showed the favorable test-retest reliability (0.73) and internal consistency (0.90) of SCRS. Since SCRS exhibited acceptable validity and reliability in a sample of Iranian students, It is suggested that this scale be used to measure self-critical rumination in Iranian students.

Abstract
This study aimed to validate the multi-dimensional scale for anti-social behavior in a higher education setting (ASB) for a sample of Iranian university students. This descriptive-evaluative study translated and validated the Persian version of (ASB) in a sample of Iranian students. 270 students of Islamic Azad University, Rasht branch participated in this study using the convenience sampling method in 2023. To examine the test-retest reliability of ASB, 50 participants were randomly selected to fill out this scale twice at an interval of two weeks. The multi-dimensional scale for Anti-Social Behavior in a higher education setting (ASB), the Dirty Dozen Scale (DD, Jonason & Webster, 2010), and the Short form of the self-compassion Scale (SCS, Raes et al., 2011) were used in this study. According to the results of exploratory factor analysis (EFA), 2 factors were identified separately, which explain 66.30% of the total variance. The results of criterion validity showed that ASB had a positive relationship with dark personality traits and a negative relationship with self-compassion (P<0.05); which respectively shows the convergent and divergent validity of this tool. According to Cronbach's alpha, results showed the favorable test-retest reliability (0.77) and internal consistency (0.89) of ASB. Since ASB exhibited acceptable validity and reliability in a sample of Iranian students, it is recommended to be used for measuring the anti-social behavior of Iranian university students.
