Objective: The aim of this study was to prepare the Persian version of the orthorexia nervosa Scale and evaluate its psychometric properties. Method: The sample of the present study consisted of 639 people aged 18 to 65 years living in Tehran who were tested using the available sampling method. The Persian version of the orthorexia nervosa Scale was prepared after the translation-retranslation process and was administered along with the eating attitude test (EAT-26) and Reef psychological well-being questionnaire (REEF-18). The validity of the scale was assessed using construct, convergent and divergent validity was evaluated through Pearson correlation. Moreover, to assess its reliability, Cronbach's alpha calculation method and composite reliability were used. Findings: The results of exploratory factor analysis indicated the existence of three factors: cognitive, emotional and clinical, and the results of confirmatory factor analysis indicated the goodness of fit and eligibility of the obtained model. Significant correlations between the obtained factors with the eating attitude test and Reef psychological well-being questionnaire also confirmed the convergent and divergent validity of the orthorexia nervosa scale. The reliability of the scale was calculated using Cronbach's alpha coefficient and obtained 0.811 for the all scales and ranged 0.69 to 0.735 for specific scales. Moreover, the composite reliability of the scales ranged between 0.78 and 0.82. Conclusion: Conclusions: In general, it can be said that the Persian version of the orthorexia nervosa Scale has a three-factor structure and has the adequate validity and reliability for use in psychological research in the Iranian sample.

Objective: In recent years, more attention has been paid to parent-focused behavioral interventions for the treatment of childhood obesity. Accordingly, this study was conducted with the main objective of reviewing the effectiveness of parent-focused interventions in the treatment of childhood and adolescent obesity, and with the sub-objective of assessing the rate of attrition in selected studies. Method: 1476 articles between1957-2021, with a variety of keywords related to intervention, parent, obesity, and overweight, in the age range of 6-18 years, from the databases of PubMed, Science Direct, and PsyINFO, were identified in the first stage. After applying the inclusion and exclusion criteria and reviewing related articles, finally, ten randomized controlled trial (RCTs) studies, that their main outcome was a decrease in body mass index (BMI), were systematically reviewed. The standard method of evaluating Population,-Intervention-Control groups- Outcomes (PICO) in selecting, and the Consolidated Standards of Reporting Trials (CONSORT) in evaluating of the quality of the articles was used. Findings: The range of decrease in standard scores of body mass index at the end of the interventions was between 0.06-0.31, and at the end of 13-24 months follow-up was between 0.16-0.42. The mean attrition rate by the end of the study was 32.3% (13% to 50%). Conclusion: Comprehensive parent-focused behavioral lifestyle interventions are generally effective in reducing children's body mass index, but it is necessary to interpret the results of current articles with caution, and to conduct comprehensive and standardized research in future.
