Shift work is an inconsistent and atypical work schedule. This study aimed to investigate the influence of shift work on the Quality of Sleep (QOS) and Executive Functions (EF). Thirty shift workers and thirty day workers first completed a demographic questionnaire. They then were tested using the Pittsburgh Sleep Quality Index (PSQI) and EF tests, including the Corsi Block-Tapping Task (CBTT), Berg's Card Sorting Task (BCST), and the Continuous Performance Task (CPT). Results were subjected to non-parametric Chi-Square Tests, the Mann-Whitney U Test, and Independent T-Tests. Shift workers had significantly poorer sleep quality than day workers, which was shown in PSQI global scale (p = 0.001), sleep duration (p = 0.042), habitual sleep efficiency (p = 0.021), and sleep disturbance (p =0.021). Concerning EF tests, shift workers performed significantly poorer on CBTT (p = 0.019) and BCST (p =0.015, 0.047) compared with day workers. Significant differences were also observed between shift workers and day workers in terms of variables of omission errors (p = 0.037) and commission errors (p = 0.041) on CPT, but no significant difference was found between shift workers and day workers in reaction time (p = 0.561). Shift work impaired EF. These findings are related to shift workers' poorer sleep and its detrimental effects on areas of the brain, which are critical for EF, such as the prefrontal area. Our results suggest the evaluation and implication of practices and policies to assuage the consequences of working in shifts.

Objective: The aim of the present study was to determine the efficacy of acceptance and commitment therapy (ACT) compared to cognitive-behavioral therapy (CBT) on anger and interpersonal relationships among male students. Method: In the present study, several universities were selected from the public universities in Tehran province, based on random cluster sampling. Then, 400 students from selected universities were selected randomly and Aggression Questionnaire (AGQ) was administered on them. After collecting information, among the participants who gained scores higher than the average, 30 were selected based on the lottery and randomly (sorting their names in alphabetical order and randomly selecting them) and then were placed randomly in ACT (n = 15) and CBT (n = 15) groups. Also, the Fundamental Interpersonal Relation Orientation- Behavior (FIRO-B) and Aggression Questionnaire (AGQ) was performed on both groups before and after intervention. Results: The results indicated that at the end of treatment, there was a significant decrease in the degree of anger among the participants and a significant improvement in all subscales of interpersonal relationships. Also, a significant difference was found between the 2 groups of ACT and CBT in terms of anger changes. Considering that the anger changes in the ACT group were higher, it can be concluded that the ACT group had more changes than the CBT group, but there was no significant difference between the 2 groups of ACT and CBT in terms of FIRO-B subscales. Conclusion: In some cases, such as anger, ACT has a better effect than CBT, and in others, such as interpersonal problems, it is as effective as CBT

Objectives: The present study aims to examine the mediating role of external shame and self-compassion in the relationship between peer victimization and depression in adolescents. Methods: This is a descriptive-correlational study. Participants were 300 middle-school students of Shahin Shahr city in Isfahan, Iran (150 girls and 150 boys), who were selected using a multi-stage cluster sampling method. The data collection tools were Multidimensional Peer-Victimization Scale, the Other As Shamer Scale, Self-Compassionate Scale-Short Form, and Mood & Feeling Questionnaire. The collected data were analyzed in SPSS v. 19 and AMOS v. 20 applications. Results: There were significant relationship among peer victimization, external shame, self-compassion, and depression (P<0.01). The measurement model had a good fitness (Root mean square error of approximation=0.037, normed fit index=0.997, comparative fit index=0.999). Path Analysis results reported that peer victimization had indirect effect on depression through mediation by external shame and self-compassion. Conclusion: External shame and self-compassion can mediate the relationship between peer victimization and depression in adolescents. Considering them in designing effective preventive and therapeutic interventions can be helpful for adolescents to cope with peer victimization and depression.

BACKGROUNDBody dysmorphic disorder (BDD) is one of the obsessive-compulsive disorders (OCD) which is very common in populations. However, the diagnosis rate is lower than the reality. BDD may lead to loneliness, jobless, avoidance of daily life and public activities. The Body Dysmorphic Disorder Questionnaire-Aesthetic Surgery (BDDQ-AS) is the validated questionnaire used to screen the BBD in patients seeking cosmetic surgeries. This study aimed to translate and validate a Persian version of the BDDQ-AS. METHODSThis analytical-descriptive cross-sectional study was conducted at Firoozgar Hospital, Tehran, Iran to validate the BDDQ-AS in Iranian society in 2020. A standard forward and back-translation procedure was followed. Overall, 79 Persian-speaking patients of both sexes referred to rhinoplasty surgery department at Firoozgar hospital were recruited. The control group consisted of 70 patients who also completed the final questionnaire. The BDDQ-AS was translated into Farsi. The final version was tested for reliability and validity in both groups. RESULTSThe internal consistency and split-half test were 89.2% and 92% respectively in rhinoplasty group. The spearman`s correlation coefficient between the scores obtained in BDD-YBOCS and BDDQ-AS was 0.757 (P<0.001) which confirmed the criterion validity and the minimum value of CVI was 0.79 that all items were relevant, transparent and simple. CONCLUSIONThe Persian version of the BDDQ-AS questionnaire consist of 6 short yes/no questions which is less time-consuming and reliable for interpreting and screening. The sensitivity and specificity of this version are 85.71% and 81% respectively, which are adequate for screening.
