Aim and Background: The aim of this research was to examine the effect of positive psychology group training on body image satisfaction in adolescent girl students of Kuhdasht, Iran. Methods and Materials: This was a quasi-experimental research with pre-/post-test design and control group. Applying researcher-made Satisfaction with Body Image Scale (SWBIS), from high Scholl girls with low body image satisfactory, 32 were randomly chosen and divided into two equal groups of experimental and control. Positive psychology group training was presented to experimental group one hour and two times a week during 14 sessions. The control group received no training. The data were analyzed using ANCOVA test. Findings: Body image scores improved at post-test stage in those who received the intervention (P < 0.001). Conclusions: It can be concluded that positive psychology group training was effective on improving body image in adolescent girl students of Kuhdasht.

Aim and Background: The motor learning skill and self-efficacy require support and feedback support. The aim of the present research was to determine the effect of positive social-comparative feedback and autonomy support on the self-efficacy and learning of throwing targeting skill in 8- to 9-year-old students in Area 9 of Tehran City, Iran. Methods and Materials: To this aim, through convenience sampling, 60 right-handed students were selected as the sample and were assigned to four 15-member groups of positive social-comparative feedback, autonomous support, positive social-comparative feedback and autonomous support simultaneously, and control according to height, weight, level of developmental skill, and the pretest scores. The acquisition stage included 6 10-trial blocks. In groups including positive social-comparative feedbacks, the participants received real feedback after each block as well as a feedback in comparison to the performance of other children, and in groups including self-efficacy support, the participants could choose the color of bags before each block. To compare the means, combined 2-factor analysis of variance (ANOVA) repeating measurement of the last factor, and between-groups one-way ANOVA with Bonferroni correction was used. Findings: The social-comparative feedback and self-efficacy support, whether separately or simultaneously in one group, could improve children’s motor performance and learning through enhancing self-efficacy. Conclusions: Moreover, the positive effect of simultaneous social-comparative feedback and self-efficacy support on motor learning is considerably remarkable.
