Abstract
The purpose of the present study is to develop and evaluate psychometric properties of the Intrapersonal and Interpersonal Skills of Couples Scale (IISCS). In terms of testing, the research method was of descriptive type and the sampled statistical population included married men and women livi
ng in the city of Tehran, Iran. In this respect, 470 Iranian married men and women (277 women and 193 men) volunteered to participate in the given study.
The resulting scale in this study was the Intrapersonal and Interpersonal Skills of Couples Scale (IISCS). To develop this scale, the first step involved planning for the subject matter of the test and the second step contained designing a questionnaire based on theoretical foundations and reviews of existing questionnaires. The given scale was implemented in two stages and the final questionnaire was analyzed in order to assess its construct validity through measurement methods including internal consistency (Cronbach’s alpha coefficient), Pearson correlation coefficient, test-retest method, exploratory factor analysis, as well as confirmatory factor analysis.
According to the findings of this study, Cronbach’s alpha coefficients (internal consistency) were from 0.65 to 0.78 and the results of the test-retest method confirmed the correlation coefficients between 0.54 and 0.81. In this regard, the results of confirmatory factor analysis revealed a goodness of fit index (GFI) equal to 0.95. Likewise, the goodness of fit index (GFI) was 0.95 and the adjusted goodness of fit index (AGFI) was equal to 0.91 which showed a favorable goodness of fit for the model. The normed fit index (NFI) and the comparative fit index (CFI) were respectively equal to 0.93 and 0.95 indicating the desirable goodness of fit for the model. Furthermore, the root mean square error of approximation (RMSEA) was 0.43 which suggested a favorable goodness of fit for the given model. The results of this study showed that the Intrapersonal and Interpersonal Skills of Couples Scale (IISCS) benefited from sufficient reliability, validity, and goodness of fit to measure such constructs among Iranian samples.

Abstract
Aim: The aim of this research was to investigate the factor structure, validity and reliability of the Protean Career Attitudes Scale of employees. Methods: This research was a descriptive research which investigated the psychometrics of the scale. The statistical population included the employees of Isfahan's engineer companies. The samples were 200 employees (including 78 females and 122 males) who were selected by cluster sampling method. Protean Career Attitudes Scale and Proactive Personality Scale were used. Findings: Data were analyzed by using factor analysis, correlation and multivariate analysis of variance. The results of the confirmatory factor analysis revealed that the factor-second order confirmatory factor model and two factors-first order confirmatory factor model were confirmed and were fit with data. Finally, two factors-first order confirmatory factor model a better fit. In the one factor model, protean career attitudes were the latent construct and in two factors model self-directed career management and values-driven were latent constructs. The correlation of Self-directed career management subscale and values-driven subscale with proactive personality scale was 0.66 and 0.53 (p<0/01). Internal consistency of self-directed career management subscale was 0.72 and values-driven subscale was 0.70. Test-retest reliability in three weeks in self-directed career management subscale and values-driven subscale were 0.89 and 0.90 (p<0.01). Moreover, the results of multivariate analysis of variance showed that men in both self-directed career management subscale and values-driven subscale had higher scores than women. Conclusions: Overall, diverse career path perspectives scale may be used as a reliable tool to assess the perspectives toward different career paths.

Abstract
Aim: Conflict of mothers and daughters-in-law is a common issue, especially in Asian countries characterized by a collectivistic culture and a patrilineal society. The main purpose of this research was the development and validation of quality of mother and daughter-in-law’s relationship scale, including construct validity, convergent validity and internal consistency. Methods: This was a correlational research. The research's statistical population included all students' mothers in city of Ahvaz. Two samples were used in this study. In the first sample, 411 subjects were selected for exploratory factor analysis; and in the second stage, a random sample of 211 subjects were selected as a multi-stage cluster sampling for confirmatory factor analysis. Subjects completed the Quality of Mother-in-Law and Daughter-in-law Relationship Scale (QMDRS) and Miller Social Intimacy Scale (MSIS). Results: The results of the exploratory factor analysis showed that this scale consists of four factors, including kindness and empathy, control, communication, and interference. The confirmatory factor analysis results confirmed the four-factor structure of this scale. Convergent validity of QMDRS is calculated by correlating it with the Miller Social Intimacy Scale. The correlation coefficient of mean in subjects in QMDRS was significant (0.20 to 0.46). According to Cronbach's alpha, the internal consistency of the QMDRS and four factors kindness and empathy, control, communication, and interference was 0.68, 0.62, 0.72, 0.78, and 0.90. Conclusion: According to the results the Quality of Mother and Daughter-in-law’s Relationship Scale (QMDRS) has sufficient validity and reliability in Iranian families.

Abstract
Aim: The aim of present research was making a test of perception of lovemaking between single students and survey of psychometric features of this tool. Methods: The research method was mixed. For this purpose, first during a qualitative study based on data-driven theory using a semi-structured interview technique, 32 students (18 girls and 14 boys) were interviewed. The sampling method was purposeful and based on theoretical saturation. The text of the interviews were identified using MAXQDA10 qualitative data analysis software. Students' coding and perception of lovemaking were identified in three categories: ethics of logical obedience, emotional self-obsession and immoral self-obsession. In the next step, based on the codes obtained from the qualitative part of the research, a questionnaire appropriate to the cultural and educational context of Iranian society was developed to measure the perception of lovemaking of single students and then 560 single students ranging in age from 19 to 33 years. (314 girls and 246 boys) Bachelor's and Master's degrees from 5 governmental and Islamic Azad universities in Tehran (Allameh Tabatabai, Shahid Beheshti, Imam Sadegh (AS), Research Sciences and Amirkabir Universities), which are in a multi-stage cluster method Were selected and answered the test. Results: The results of confirmatory factor analysis showed that the scale of love perception contains 18 questions and includes three confirmed categories of ethics of logical obedience (questions 1, 2, 3, 4, 5, 6), emotional self-obedience (questions 13, 14, 15, 16, 17, 18) and immoral self-obsession (questions 7, 8, 9, 10, 11, 12) of lovemaking. Model fit indices in confirmatory factor analysis confirmed the validity of this scale. Conclusion: Therefore, based on the findings, the students' love perception test can be used as a valid and valid tool to measure and evaluate the love perception of single Iranian students.
