The present study was conducted with the aim of determining the difference between social anxiety, self-efficacy, cognitive emotion regulation and hope among people with obesity and normal weight. The research method was causal-comparative. The statistical population of this research was all obese people who referred to Rasht nutrition counseling centers and their companions in the fall of 1401. According to available sampling method, 60 people (30 women and 30 men) were selected for each group, but due to dropout, 56 people from the clinical group and 57 people from the normal group were examined (n=113). The data were collected by the Social Phobia Inventory (Connor, et al., 2000), The self-efficacy scale (Sherer, et al., 1982), the Cognitive Emotion Regulation Questionnaire (Garnefski, et al., 2001), Snyder Hope Scale (Snyder, et al., 1991), and Body Mass Index. Research data were analyzed by Multivariate analysis of variance (MANOVA) and independent t-test. Findings of the first hypothesis showed that there was significant differences between two groups of obese and normal-weight men and women in the components of social anxiety including anxiety (F=10.66; P<0.01), avoidance (F=4.84; P<0.01) and physiological discomfort (F=239.73; P<0.01). Findings of the second hypothesis showed that there was significant differences between two groups of obese and normal-weight men and women in the components of self-efficacy including educational self-efficacy (F=159.98; P<0.01), job self-efficacy (F=146.49; P<0.01), and social self-efficacy (F=6.96; P<0.01).
