Social comparisons are an essential source of information about the self.  This research aimed to evaluate the factorial structure and psychometric properties of the Persian version of the social comparisons orientation scale. 211 high school students of Noshahr City in 2015-2016 academic year were selected by cluster randomized sampling method. They completed the Persian version of social comparisons orientation scale and self-efficacy and optimism subscales of psychological capital scale. To analyze the data, Cornbrash’s alpha coefficient, correlation coefficient, exploratory and confirmatory factor analysis were used. Primary Scale Reliability that calculate through Cronbach's alpha coefficients was 0/71. Ability and opinion factors were extracted as using principal components analysis method and Varimax rotation. Cronbach's alpha coefficients of ability factor, opinion factory, and Persian version of social comparisons orientation scale were found to be 0/72, 0/80, and 0/80 respectively, which were statistically significant. The scale validity was confirmed by using criterion and construct validity. Results of exploratory factor analysis supported the factorial structure of two-factor model. According to the results, it can be concluded that this scale has a good validity and reliability for Iranian samples and can be used in future studies related to social comparison.

Under stressful circumstances, such as confrontation with a life-threatening disease, people often make comparisons with each other, which can have effects on their psychological and physical well-being. This research aimed to evaluate the validity and reliability of Persian version of social comparisons during chronic illness scale.
The study was descriptive with a correlational design. Among the diabetic patients referring to the Goodarz and Sadoghi hospital hospitals of Yazd in 1396, 200 subjects were randomly selected. Validity of this scale was determined by using content, criterion and construct validity methods. In order to assess the construct validity, exploratory factor analysis and calculating the correlation coefficient of factors and items with total score, and to assess of criterion validity, the social support (Sohrabi et al, 2007) and world health organization's WHOQOL-BREF quality of life assessment scales as a criterion were used. Also, the reliability of the scale was evaluated using the Cronbach's alpha coefficient. Cronbach's alpha coefficient, Pearson correlation coefficient and exploratory factor analysis methods were used and data was analyzed using SPSS version 21software.
Negative interpretation and Positive interpretation factors were extracted as using principal components analysis method. The correlation coefficient between the items with the total score was between 0.31 to 0.87, which were significant and confirms coefficients construct validity of the scale. Also, the correlation coefficients between this scale with social support and quality of life were 0.56 and 0.72, which confirmed the criterion validity. Cronbach's alpha coefficients of negative interpretation factor, positive interpretation factor and total scale were found to be 0.98, 0.86, and 0.92 respectively.
According to the results of this research, the Persian version of the social comparison scale during chronic illness can be used as a valid and reliable tool for researchers in the field of social comparison in people with chronic disease.

This study aimed to investigate the effectiveness of group training of the concepts of Choice Theory in addict's quality of life.
A quasi-experimental research design along with pre-test and post-test and follow-up and control group was employed for the conduct of this study. The population of this study consisted of the addicted men who referred to addiction treatment centers in Ahvaz in 2015. From among these addicts, 50 subjects were randomly selected using purposive sampling and were randomly assigned to two groups. The participants completed Quality of Life Questionnaire in three stages (pre-test, post-test and follow-up after 60 days). The experimental group received ten 90-minute sessions of group training on the concepts of Choice Theory (once a week).
The results showed that group training of the Choice Theory concepts leads to enhanced quality of life in physical, psychological, social, and environmental domains in addicted people.
Group training of Choice Theory concepts can enhance the quality of life in addicts.
