Overview

Cross-sectional study identifies distinct and shared temperament correlates of behavioral addiction risks in medical students, highlighting self-directedness as a central vulnerability factor.

Key Points

  • To estimate the prevalence of multiple behavioral addiction risks among medical students and determine their shared and behavior-specific temperament and character correlates.
  • Cross-sectional survey of 385 medical students at a public university.
  • Assessed personality traits (Temperament and Character Inventory), psychological distress (PHQ-4), and seven behavioral addiction risks using validated instruments.
  • Evaluated risks using scale-specific thresholds and conducted hierarchical regression analyses adjusting for age, sex, and psychological distress.
  • Threshold-based prevalence was 17.1% for social media addiction, 12.7% for compulsive buying, 9.6% for food addiction, 8.6% for problem gambling, 2.3% for cyber pornography use, 2.3% for internet gaming disorder, and 1.8% for exercise dependence.
  • Females exhibited higher compulsive buying scores, whereas males had higher scores for cyber pornography use, problem gambling, internet gaming disorder, and exercise dependence.
  • Lower self-directedness was independently associated with higher social media addiction, compulsive buying, and internet gaming disorder scores after controlling for age, sex, and psychological distress.
