Prevalence and Influencing Factors of Body-focused Repetitive Behaviors in Turkish Medical Students
Öz
Background/Aims: Body-focused repetitive behaviors (BFRBs) such as skin-picking, trichotillomania, nail-picking, nail-biting, lip-biting and skin-biting have adverse physical and psychological effects. This study aimed to investigate the prevalence and associated factors of BFRBs in a sample of Turkish medical students.
Methods: An online survey was used to investigate the prevalence of six BFRBs —skin-picking, trichotillomania, nail-biting, nail-picking, lip-biting and skin-biting-- and psychological factors such as anxiety, depression, stress levels, impulsivity and difficulties in emotional regulation (DER) in a sample of 200 medical students. Skin Picking Scale-Revised (SPS-R), Massachusetts General Hospital Hairpulling Scale (MGH-HPS), Depression Anxiety Stress Scales-21 (DASS-21), Barratt Impulsiveness Scale–Short Form and Difficulty in Emotion Regulation Scale—Brief Form and specific questions for four BFRBs (nail-picking, nail-biting, lip biting and skin biting) were administered.
Results: The prevalence of at least one BFRB disorder was 28.0% (n=56). The most common diagnoses were skin-picking (17.0%) and trichotillomania (10.5%), followed by skin-picking (9.0%), lip biting (8.5%), nail-picking (7%) and nail-biting (5.0%). The gender difference was found only in skin-picking disorders (females=22.9%; males=8.5%). Students with BFRB disorder (n=56) were found to have higher levels of anxiety, depression, stress, impulsivity and DER. Students in 2nd, 3rd and 5th grade are more likely to have BFRB disorders than interns. DER was a partial mediating variable between impulsivity and the presence of BFRB disorder.
Conclusions: The findings of the study suggest that BFRBs are common among medical students and that these behaviors are associated with psychological factors such as depression, anxiety, stress levels, impulsivity and difficulties in emotion regulation. Screening programs and intervention strategies for BFRBs in medical students should be developed, and it is recommended that psychological factors should be considered in these interventions, emotion regulation and stress management skills should be significantly improved, and comorbid depression and anxiety should be treated.
