- چکیده: The purpose of this research is to investigate the effect of art therapy based on painting therapy on 30 children recruited from elementary school boys with the symptom of social phobia who were 7-12 years old. This research is an experimental one with pretest and posttest and control group. In this prospective study a group of 30 elementary school boys with symptoms of social phobia were randomly assigned to two experimental and control groups. To find and select the main subjects, two steps were taken. At the first step, children obtaining scores higher than the cut-off point in the CHILD SYMPTOM INVENTORY-4 were selected, and at the second step and for the final selection, children were attended the Structured Diagnostic Interview based on criteria. The researcher adopted interview/observation and the document analysis for qualitative study and went through the painting therapy for 10 sessions twice per week, and each session lasted 45 minutes based on discussion and reviewing from parents and the teacher. An experimental pretest-posttest control group design was used in this regard. The data were analyzed using descriptive statistics as well as ANCOVA. Findings indicated that the experimental group did have a significant decrease in the symptoms of (SP) while the control group showed no significant difference.

- چکیده:
- چکیده انگلیسی: The main criterion in investment decisions is to maximize the investors utility. Traditional capital asset pricing models cannot be used when asset returns do not follow a normal distribution. For this reason, we use capital asset pricing model with independent and identically asymmetric power distributed (CAPM-IIAPD) and capital asset pricing model with asymmetric independent and identically asymmetric exponential power distributed with two tail parameters(CAPM-AIEPD) to estimate return and risk. When the assumption of normality is violated, the first and second moments lose their efficiency in optimization and we need to use the third and fourth moments. For the first time, we propose independent and identically asymmetric exponential power distributed with two tail parameters. Then, we use higher moments optimization with unequal weights to optimize portfolios. The results indicate that capital asset pricing model with independent and identically asymmetric power distributed (CAPM-IIAPD) is better than asymmetric independent and identically asymmetric exponential power distributed with two tail parameters(CAPM-AIEPD) to estimate return and risk. Adjusted Sharp ratio in portfolio optimization in second moments are higher than others. Adjusted returns to risk in third and fourth moments in the CAPM-IIAPD model significantly differ from the CAPM-AIEPD model and have a better performance.
