Methods: In this study, a correlational design was used and 270 individuals (Male: 135, Female: 135) with age of 17 to 40, citizens of Tehran, who were selected by the available random sampling were included. They completed Neo-PI questionnaire, Fisher body image scale (Fisher, 1970), and Sexual Self-schema Scale (Cyranowski & Andersen, 1998).
Results: The results show a meaningful and positive relationship between neuroticism and body image dissatisfaction there is also a meaningful and negative relationship between conscientiousness, openness to experience, extroversion, agreeableness and body image dissatisfaction. General sexual Self-schema, the personality factors of neuroticism and agreeableness can predict 26.9 percent of body image dissatisfaction variance.
Conclusion: Low scores in positive personality characteristics such as conscientiousness, openness to experience, extroversion and agreeableness and high scores in the neuroticism with poor sexual Self-schema make the individuals vulnerable to negative messages about their body sizes and shapes that finally results in their body image dissatisfaction.
