Abstract
This study was an attempt to investigate the theoretical bases of the one of the important theories in the domain of positive psychology that is, flow experience, and it also investigated the factor structure of flow state scale in physical education students of Tehran universities. This scale contained 9 factors, and 4 questions were considered for each factor. 198 physical education students were selected out of 6 universities located in Tehran as the samples of the study. Construct validity and reliability of the flow state scale were tested through factor analysis and Cronbach’s alpha Congruent validity of the flow state scale was tested through correlation coefficient with the peak-experience questionnaire(10 items).The results indicated that 9 factor model confirmed the flow state. Finally, it should be recommended that for the subsequent research some problematic questions, research method and the samples should be reviewed

Abstract
The aim of this research was to investigate the Factor Structure and Psychometric Properties of the Persian version of State Adult Attachment Scale (SAAS). Using stratified random sampling method, 321 students (148 male and 173 female students) from Shiraz University were selected. Participants completed Persian version of State Adult Attachment Scale (SAAS), revised version of the adult attachment scale (RAAS), Beck Depression Inventory (BDI–II) and Beck Anxiety Inventory (BAI). The construct validity of the Persian version of State Adult Attachment Scale (SAAS) was assessed via factor analysis and internal correlations. Also, Concurrent validity coefficients of this scale were calculated based on the correlations of this scale with the revised version of the adult attachment scale (RAAS), Beck Depression Inventory (BDI–II) and Beck Anxiety Inventory (BAI) scores. Moreover, using Cronbach’s Alpha the reliability of the Persian version of State Adult Attachment Scale (SAAS) was assessed. Principal component analysis with Varimax-rotation showed the three factors including Secure, anxious and avoidant attachments which were in accordance with factor structure of SAAM in major population. Result of internal correlations and correlations with BAI, BDI-II and RASS, revealed good construct and Convergent validity. Finally, reliability of these subscales were reached between 0/72 - 0/84 according to the Cronbach’s Alpha. According to the results of this study, SAAM can be used for the Iranian population in clinical and research fields as a reliable and valid scale.

Abstract
With the development of Brief Self-Control Scale most studies in this field has used it widely for the measurement of the general capacity of self-control. Discordant findings on the adaptiveness of self-control have brought about doubt concerning unidimensionality of this scale. The aim of the present study was to investigate the factor structure of BSCS in Iran. 247 Iranian university students (188 women, 53 men and 6 undefined) completed the following scales: BSCS, Rumination Scale, Penn State Worry Questionnaire, Vitality Scale, & Anxiety and Depression Scale. Confirmatory factor analysis (CFA) showed that one-factor structure of BSCS did not fit the data well. Explanatory factor analysis (EFA) proposed two-factor structure of the scale that fit the data well and performed better than one-factor structure in a new CFA. The results were discussed through considering the viewpoints concerning the two facets of self-control and they confirmed the need for reviewing the theories and research on the inhibitory and initiatory facets of self-control.

Abstract
The purpose of this study was to investigate the factor structure, reliability and validity of Gender Identity/Gender Dysphoria Questionnaire in adolescent girls. Using multistage cluster sampling method, 400 female students aged 16-18 years old in Isfahan Secondary School were selected as the sample. Data were collected using Mental Health Questionnaire (Najjarian & Davoodi, 2001), Sexual Identity Questionnaire (Akefi, 2012) and Sexual Discontent and Sexual Identity Scale (Deogracias, 2007). Cronbach's alpha, test-retest reliability, exploratory and confirmatory factor analysis, and concurrent validity were used for data analysis. Reliability of test-retest and internal consistency were 0.93 and 0.92, respectively. The factor structure of gender dissatisfaction and gender identity scale was investigated using both exploratory factor analysis and confirmatory factor analysis. The results of exploratory factor analysis with principal component analysis and varimax rotation indicated that there were four factors in this scale that explained 63.44% of the total variance and the results of confirmatory factor analysis showed four factor model of There is a good fit. Correlation coefficients indicated that concurrent validity of gender dissatisfaction and gender identity scale with other instruments was desirable. The 27-item scale of gender identity/gender dysphoria has good validity.
