This dissertation aimed to provide a deeper understanding of body image concerns of males and to enlighten the underlying mechanism of muscle dysmorphia. In line with this aim, three studies were designed. In the first study, body image concerns were compared across genders, and the predictive effects of basic psychological needs on these concerns were investigated. The results revealed that although there was no gender difference in terms of body image concerns, there was a gender difference in terms of the manifestation of these concerns. Besides, significant effects of basic needs on these concerns were found. In the second study, semi-structured interviews were carried out with six males engaging in regular bodybuilding activities to understand their motivation for these activities. According to the results, with the aim of compensating for inferiority feelings, men engaged in bodybuilding activities, these activities resulted in muscle-contingent self-worth and positive or negative emotions, which forced men to think that they should constantly improve their muscles. In the last study, the predictors of muscle dysmorphia and life satisfaction were examined based on Basic Psychological Needs Theory. The findings indicated that frustrated basic needs are predisposing factors of muscle dysmorphia. Additionally, the significant associations of life satisfaction with basic needs were found. Overall, the findings suggested that (1) males experience a similar level body image concerns with females but their concerns are more related to their muscles, (2) trying to compensate inferiority feelings and unsatisfied basic needs through having a muscular body may lead to muscle dysmorphia.

An Experimental study on women to understand negative mood, appearance anxiety, body dissatisfaction, and body shame considering adlerian theory and objectification theory
Yılmaz, Tuğba; Sakallı Uğurlu, Nuray; Department of Psychology (2017)
Objectification theory posits that women internalize males’ sexualizing gaze on them and they begin to pay more attention to their appearance than their feelings. This phenomenon is called self-objectification and it has some psychological and experiential costs, such as increased risk of eating disorders. Likewise, Adlerian theory suggests that women are exposed to masculine superiority persistently in many domains of life. Societal norms require them to be thin and to accept culturally-defined beauty idea...
