Body dysmorphic disorder and personality in breast augmentation: The big-five personality traits and BDD symptoms

Breast augmentation is one of the most performed cosmetic surgeries in the world. Personality traits predict the presence of psychological and social factors that may affect the patient satisfaction with a cosmetic surgical procedure and may be risk factors for body dysmorphic disorder. The aim of this study was to assess symptoms of body dysmorphic disorder in patients undergoing breast augmentation and identify their personality traits.

Thirty-six women with hypoplasia of the breast (Sacchini index < 9 cm), a mean age of 28.1 years (SD = 6.2), body mass index ≤ 25 kg/m², and no history of breast surgery or breast-associated conditions were included in this prospective study.The Brazilian versions of the Structured Clinical Interview (SCID-I), Big Five Inventory (IGFP-5), and Body Dysmorphic Symptoms Scale (BDSS) were applied preoperatively and at 2 and 4 months after breast augmentation.

Personality traits were associated with symptoms of body dysmorphic disorder. A significant decrease (p< 0.001) in IGFP-5 scores on the Conscientiousness dimension, symptoms of body dysmorphic disorder (BDSS scores), and the number of patients with body dysmorphic disorder (SCID-I) were observed among different time points. In the study population, breast augmentation decreased the symptoms of body dysmorphic disorder, psychosocial impairment, and mean scores on Conscientiousness.

Personality traits varied in intensity and overlapped over time, and were associated with core symptoms of body dysmorphic disorder and the onset of body dissatisfaction.
