Modeling of body image concern based on obsessive-compulsive disorder, perfectionism and eating attitudes mediated by basic psychological needs in girls

The aim of this study was to evaluate the model of girls' body image concern based on obsessive-compulsive disorder, perfectionism, and eating attitudes mediated by basic psychological needs. This research was a correlational study based on structural equation modeling. The study population was all female students in the free universities of Golestan province in 2016-2017. 500 students were selected through cluster sampling for the sample group. Research data through Body Image Concern Questionnaire (BICI) Littleton et al. (2005), Ahvaz Perfectionism (1999), Obsessive-Compulsive Disorder (OCI-R) (2002), Eating Attitude (Eat-26) Garner and Garfinkel (1979), and the basic psychological needs of Desi and Ryan (2000) were collected. In order to study the theoretical model of the research, the main variables were entered into Lisrel software (Lisrel 8.71) and through this software, SEM analysis was performed. Obsessive-compulsive disorder and perfectionism have a positive and significant relationship and attitudes to eating have a positive relationship without statistical significance with body image concern. And basic psychological needs have played a weak mediating role. Research variables predict up to 36% of body image concerns (p> 0.01). According to the results of the proposed research model, it has a suitable fit.
