Depression as a usual disorder in coronary heart disease decreases mental health and ejection fraction of these patients. The purpose of this study was to investigate the effectiveness of individual andgroup cognitive-behavioral therapies on depression decrease and ejection fractionincrease in coronary heart disease, and to compare the two psychotherapy methods.Subjects were coronary heartdisease patients between ages of 30 to 60 with medium or severe depression. The subjects were randomly assigned to three matched groups, including two experimental groups for individual cognitive-behavioral therapy (n=20) and group cognitive-behavior therapy (n=16) and a control group (n=20). The control group received no psychological treatment. The patients were selected using available sampling method. All participants completed the Beck Depression Inventory-II, as well as, Ejection Fraction Test as pre-tests and post-tests.Data was analyzed using repeated measures and Scheffé test. Individual and group cognitive-behavioral therapies hadsignificant effects on depression reduction, but they had no effect on ejection fractionincrease in coronary heart disease patients. Regarding to depression reduction, there was no significant difference between the two methods. Individual and group cognitive-behavioral therapies can reduce the rate of depression and lessen the need to psychiatric drugs in coronary heart disease patients.

The aim of the current study was to investigate the effect of Cochran's career narrative therapy on academic procrastination of blind students. This is a quasi-experimental study with pretest-posttest design with control group. The statistical population of the study was all of blind students in University of Isfahan and Islamic Azad University of Khorasgan. 30 students were selected by using available sampling method and randomly divided into experimental and control groups (each group consisted of 15 students). The experimental group participated in seven sessions weekly (each session lasted 3 hours). The data was gathered by using Academic Procrastination Questionnaire and analyzed using SPSS-21. The results of the covariance analysis showed that narrative therapy decreased procrastination, in preparing for tests, and academic tasks (p

The purpose of the presentstudy was designing and testing a model of the casual relationships between sociotropy/autonomy, perception of stressful events and depression symptoms. Hypothesized model, includes sociotropy and autonomy as precedents, perception of interpersonal and achievement stressful events as mediators, and depression symptoms as outcomes variables. The sample consisted of 357 participants (123 male and 234 female) of undergraduate students at Shahid Chamran University who were selected using stratified random sampling method. The research instruments were Revised Personal Style Inventory (PSI-II), Life Experiences Survey (LES) and Beck Depression Inventory (second edition ((BDI-II). Structural equation modeling (SEM) through AMOS-18 and SPSS-18 software packages was used for data analysis. Bootstrap procedure was used for estimating the indirect effects. The primary analysis indicated that hypothesized model has a poor fit with the data. Better fit was achieved by applying some modifications in the final model.

Perfectionism as a stable personality characteristic that influences various aspects of human life in a complex way. Several studies show that perfectionists reduce their anxiety by doing procrastinating behaviors. So, the purpose of this study was to investigate the mediating role of cognition avoidance and anxiety as cognitive factors in the relationship between perfectionism and procrastination. For this purpose, a sample of 278 undergraduate, master and doctoral students (118 male and 160 female), with a mean age of 25.4 and standard deviation of 5.50 from five state university were selected by multi-stage cluster sampling method. In order to collect data, students answered Frost Multidimensional Perfectionism Scale (MPS), Solomon and Rothblum Academic Procrastination Scale, DASS-21 Scale and Cognition Avoidance. In order to analyze data, structural equation modeling (SEM) has been used. The results showed that there were significant and positive causal relationships between perfectionism, anxiety and procrastination and the mediating role of cognition avoidance, indirectly through anxiety in the relationship between perfectionism and procrastination has been verified. Thus when cognition avoidance causes more anxiety in people who are perfectionist, this leads to more procrastination.

This study was carried out to design a model forteacher personal efficacy from school climate and teacher collective efficacy - social variables.In this study, 255 teachers from elementary schools in Bajestan city were selected with multistage random sampling method. Instruments of the study were Teacher Sense of Efficacy Scale (Short form), School Climate Index and Collective Teacher Belief Scale. Results of the study showed that all absolute, comparative and parsimonious fit indices were suitable for the supposed model. According to this model, indirect path from school climate towards teacher personal efficacy, via collective teacher efficacy, was positive and significant. Also direct path from collective teacher efficacy towards teacher personal efficacy and direct path from school climate towards teacher collective efficacy were positive and significant, too. Results of current study showed the importance of mediation of collective teacher efficacy in relationship between school climate and personal teacher efficacy, indicating the neccessity of group activites among school teachers.

The aim of the present study was to investigate the state-trait anxiety and difficulties in emotion regulation based on personality dimensions of sensitivity to punishment (SP) and sensitivity to reward (SR). For this purpose, participants were male students in Urmia University, who were selected by their extreme scores on the Sensitivity to Punishment and Reward Sensitivity Questionnaire and were assigned to four groups: High sensitivity to punishment (HSP), low sensitivity to punishment (LSP), high sensitivity to reward (HSR) and low sensitivity to reward (LSR). Then, State-Trait Anxiety and Difficulties in Emotion Regulation Questionnaire were administered to each personality group (individually).The collected data were analyzed by using multivariate analysis of variance (MANOVA), one-way ANOVA and post hoc tests. Results showed that there were a significantdifferences between the four groups based onstate-trait anxiety and difficulties in emotion regulation. It seems that high sensitivity to punishment (HSP) associatedwith more experienced anxiety and more difficulties in emotion regulation.

The aim of this research was to determine the role of transformational leadership and job resources in predicting flow at work and the relationship of flow at work with psychological well-being and creativity. The statistical population comprised of all employees of Maroon oil and gas Production Company, that 221 of them have been selected by simple random sampling method. The instruments were Flow at Work (Bakker, 2008), Job Resources (Xanthopoulou, 2007), General Transformational Leadership (Carless, Wearing and Mann, 2000), Psychological Well-being (Ryff, 1989) and Organizational Creativity (Zhou and George, 2001). A correlation and multiple regression analysis were used to analyz data. The results showed that transformational leadership and job resources had positive and significant role in predicting the flow at work respectively. In addition flow at work and its components had positive and significant relationships with psychological well-being and organizational creativity. The results of regression analysis showed that absorption to job and work enjoyment predicted psychological well-being and organizational creativity more strongly.

The aim of the present study was to determine the effects of training forgiveness therapy on controlling anger among the female high school students. The population was students living in Tehran in 2009-2010. Through multi-stage sampling method, 50 students were selected and randomly assigned to 2 groups of experimental and control. In order to test the hypothesis of the study, the quasi-experimental design of pre-test and post-test, with control group, was used and the extent of anger in the students was measured with the Spiel Berger State-Trait Anger Size (STAXI-2). Then the experimental group received 10 sessions of 90 minute training in forgiveness therapy. The use of MANOVA showed that training forgiveness therapy affected the control of anger among the female high school students. Training forgiveness therapy also affected subscales of state anger, trait anger, and anger expression in female high school students. However, it had no effect on subscales of anger expression-out, anger control-out and anger control-in. Therefore, it can be concluded that the training of forgiveness therapy has effects on controlling anger in female students, and can be effectively used for the treatment of anger and aggression.
