This research is done in order to investigate psychometric properties of the Persian version of the Basic Beliefs Inventory (BBI, Catlin and Epstein, 1992). Participants were 592 students (333 boys and 259 girls), sampled through multistage cluster sampling method, from high schools of Tehran. Principal components analysis with varimax rotation showed that Persian version of the BBI includes five factors: meaningful world, favorable relations, benign world, favorable self, and others, support. The five-factor structure, as model fit indices show, was confirmed by confirmatory factor analysis. Internal consistency of each subscale, ranging from (0.66 to 0.87), was at an acceptable level. In addition, correlation coefficient of the test-retest implementation of the scale was high (r=0.83, p<0.01) which shows the BBI is reliable. In brief, based on our results, the Persian version of the BBI can be used as a valid and reliable measure in Iran.

The aim of this study was to investigate the reliability and validity of the Rejection Sensitivity Questionnaire (RSQ) in university students. The research sample consisted of 325 undergraduate students from the University of Isfahan (170 female, 150 male). Who were selected randomly through cluster sampling. The instruments used in this research were Rejection Sensitivity Questionnaire (RSQ), Penn State Worry Questionnaire, and Rosenberg Self-Esteem Questionnaire. In order to assess the questionnaire's reliability, Cronbach's alpha was used. Correlation coefficient, exploratory and confirmatory factor analysis were used to assess construct validity of RSQ. Cronbach’s Alpha of the questionnaire was 0.84. In exploratory factor analysis, 2 factors (1- response expectation, 2- worry of unacceptance of request) were extracted which explained 28.28% of total variance. Confirmatory factor analysis confirmed these two factors. Penn State Worry Questionnaire and Rosenberg Self-Esteem Questionnaire were used to assess the convergent and divergent validity of the RSQ respectively. Both of them correlated significantly with RSQ. There was no difference between RSQ scores in males and females. The results of this study showed that the RSQ had satisfactory reliability and validity coefficients and can be a suitable tool for measuring rejection sensitivity in Iranian students in future research.

this study was designed to examine the effectiveness of group behavioral activation treatment on depressive symptoms, and its effects on dysfunctional attitudes, a cognitive construct regarded to play an important role in depression. Twenty four university students suffering from depressive symptoms, were randomly assigned to two groups: experimental group (n=10) and control group (n=14). The experimental group was treated through 5 sessions of group behavioral activation treatment. Depressive symptoms and dysfunctional attitudes in both groups were assessed before and after treatment sessions. Improvement of depressive symptoms and dysfunctional attitudes in experimental group were significantly more than control group. Effectiveness of a brief and purely behavioral group therapy in reducing depressive symptoms and dysfunctional attitudes has important theoretical and practical implications.

Motivation plans have received considerable attention in the organizational literature and have been used to predict a variety of important individual and organizational outcomes such as job satisfaction, job involvement, organizational citizenship behavior, psychological empowerment, job performance, and job engagement. The aim of this study was to investigate the relationships between job motivations with job engagement. In a Cross-sectional correlative study, a sample of 315 employees was selected through stratified random sampling from a great industrial organization’s whole staff. The validities of all the questionnaires used were confirmed by confirmatory factor analyses and the reliabilities of the questionnaires were con-firmed measuring the Cronbach’s Alpha. Data were analyzed using Pearson correlation coefficient and stepwise regression analysis. The results indicated that there is significant and positive correlation between all antecedent variables except job self-efficacy with job engagement and also between job controls with absorbtion. In addition, the results of regression analyses showed that self-regulation, organizational justice, and job control had the most important role in predicting job engagement, vigorance, and dedication, but only self-regulation had the most important role in predicting absorbtion. This study describes a process that motivating employees through job motivation in work environments can predict their job engagement.

This study aimed to investigate the effectiveness of psychological capital inter-venetian model of Luthans on psychological capital of the experts working in Iran Khodro Diesel Company. The research was experimental with pretest-posttest design. Statistical population included 650 individuals. Sixty participant were selected using random sampling method and were randomly assigned to two groups of 30 subjects. Psychological Capital Questionnaire was used as a measurement tool. First, this questionnaire was used as the pretest and the experimental group received psychological capital intervention model of Luthans in 10 two-hour sessions. Participants Completed Psychological Capital Questionnaire after intervention again. Analysis showed after implementation of psychological capital intervention model of Luthans, there was a significant difference between the scores of control group and experimental group. The scores for psychological capital and subscale of hope, self-efficiency, and resiliency increased, while there was no significant difference in optimism scores. It can be stated that psychological capital intervention model has been effective in increasing psychological capital and subscales of hope, self-efficiency, and resiliency.

The purpose of this study was to examine the relationship between perceived autonomy-supportive behaviors of coaches with psychological needs satisfaction, self-determined motivation, and sport commitment of elite female players in handball league. The research method was descriptive, namely survey. To do so, the statistical population of this research that consisted of 237 female players was selected as the sample too. Players responded to a few questionnaires: Perceived Autonomy-Support Scale for Exercise Settings (PASSES), Psychological Needs Satisfaction (PNS), Sport Motivation Scale (SMS), and Sport Commitment Model Scale (SCMS). Data were analyzed using Pearson correlation coefficient and Structural Equation Models (SEM). The findings showed that autonomy-supportive behaviors of coaches had significant positive correlation with psycho-logical needs, intrinsic motivation, introjected regulation, and indentified regulation. However, the correlation between autonomy-supportive behaviors of the coaches with amotivation was negative and significant. In addition, intrinsic motivation, introjected regulation, and indentified regulation had significant positive correlations with sport commitment in players. The results of path analysis offered support for the proposed model. Total mediation was supported in the case of psychological needs satisfaction, intrinsic motivation, introjected regulation, and indentified regulation in the relationship between autonomy-supportive coaches and sport commited players. The results provide support for the self-determination theory in elite players.
