Objective: Today, eating disorders are increasing among adults and their negative consequences have caused health concerns. Therefore, identifying the factors associated with these behaviors can help to prevent them. In this regard, the aim of this study was to investigate the relationship between perfectionism and childhood trauma with disordered Eating Behaviors and the mediating role of body image dissatisfaction. Method: among all students of Islamic Azad universities in Tehran 400 students were selected by available sampling method that 324 participants were entered in the analysis. The tools of this study include Eating Disordered Behavior Scale (EAT-26), Hill’s Perfectionism Inventory (HPI), Body Image Concern (Littleton et al., 2005) and Childhood Trauma questionnaire (CTQ). Findings: The results of the path analysis showed that Body image dissatisfaction mediated the relationship between perfectionism and childhood trauma and eating disorders (P<0.05). Conclusion: it seems that people who have been traumatized, set high standards and compensatory measures, such as disturbed eating behaviors, because of the distorted image they may have of themselves. Body image dissatisfaction can also reinforce perfectionist efforts and intensify compensatory eating behaviors in order to idealize the body.

Objective: Adopting a balanced diet promotes human health. However, excessive focus on healthy eating can lead to food obsession, which is termed orthorexia nervosa (ON). The aim of this study was to determine the psychometric properties of the Persian version of the Orthorexia Nervosa Scale (ONS). Method: The statistical population of this study consisted of all undergraduate students of the Islamic Azad University, Tehran Science and Research Branch in the academic year 98-99, among whom 322 students (201 females, 121 males) were selected by multistage sampling, and they responded to the Orthorexia Nervosa Scale (ONS), the Eating Attitude Test (EAT-26), the Obsessive-Compulsive Inventory (OCI-R), the Multidimensional Perfectionism Scale (MPS), the Body Image-Acceptance and Action Questionnaire (BI-AAQ), and the NEO Five Factor Inventory (NEO-FFI). The data were analyzed by exploratory factor analysis, confirmatory factor analysis, Cronbach’s alpha and Pearson correlation using SPSS and AMOS. Findings: Results of the exploratory factor analysis showed 2 factors with eigenvalues higher than 1 which explained 41/92% of the total variance. Also, confirmatory factor analysis indicators implied the optimal fitness of two-factor model of this scale. The total reliability of the scale was estimated to be respectively 0.78 and 0.81 using Cronbach’s alpha and split half. Convergent validity and divergent validity were also confirmed by calculating scale correlation through the aforementioned scales (p<0.05). Also, this scale had a positive and significant correlation with neuroticism (p<0.01). Conclusion: The Orthorexia Nervosa Scale has a relatively proper validity and reliability for being used in Iranian samples and can be a suitable tool for researches of this field.

Objective: The psychological variables are one of the important factors in people's tendency to cosmetic surgery. The current research has aimed at investigating the mediating role of cognitive emotion regulationstrategiesand defense mechanisms in the relationship between perfectionism and anxiety sensitivity in cosmetic surgery applicants students. Method: This study was a correlational study. The statistical populationincluded all undergraduate students of Payame Noor University of Rasht in the academic year 1397-98 who were seeking cosmetic surgery. The sample consisted of 335 people (308 female and 27 male) who were selected by available sampling method. Instruments used in this study included the positive and negative perfectionism scale (PNPS), anxiety sensitivity index (ASI), cognitive emotion regulation questionnaire (CERQ) and defense style questionnaire (DSQ). Findings: Path analysis method showed that the anxiety sensitivity in cosmetic surgery applicants is influenced by perfectionism, cognitive emotion regulation and defense mechanisms. Also, cognitive emotion regulation and defense mechanisms played a mediating role in the relationship between perfectionism and anxiety sensitivity. To evaluate the model, CFI (0.91), NFI (0.93), GFI (0.94) and RMSEA (0.07) indices were used and the results indicated that the proposed model fits well with the data. Conclusion: In the formation of anxiety sensitivity, psychological factors such as perfectionism, cognitive emotion regulation, and defense mechanisms are involved. Therefore, the findings of this study have important implications for the rooting of psychological problems in these individuals.
