Despite abundant research, there are still ambiguities and challenges about such variables as thought control strategies, valued living and appearance-based rejection sensitivity in individuals with body dysmorphic disorder. This descriptive) casual-comparative( study compared thought control strategies, valued living and appearance-based rejection sensitivity among college students with and without body dysmorphic disorder. Out of the statistical population of the study, all male and female students of Guilan University in the academic year of 1399-1400, 110 individuals with body dysmorphic disorder and 163 individuals without body dysmorphic disorder were sampled based on availability sampling method. Data were collected using questionnaires on thought control, valued living and appearance-based rejection sensitivity. The results showed that in the students with body dysmorphic disorder, thought control strategies and appearance-based rejection sensitivity were significantly higher and valued living was significantly lower (p≤0.01). As for the thought control strategies, the body dysmorphic disorder students used worry, punishment and social control to a greater extent, and strategies of distraction and reappraisal to a lesser extent; concerning valued living, the importance and consistency attributed to domains of valued living was lower in the body dysmorphic students (p<0.01). These findings have implications for the pathology, prevention and treatment of the disorder.
