Screening of substance use and mental health problems among Spanish medical students: A multicenter study

This study aimed to determine the prevalence of substance consumption and mental health problems among Spanish medical students, and their association with sociodemographic factors.

A multicentre cross-sectional study was conducted. Self-reported data on sociodemographic and clinical characteristics were collected, including BDI-II, PHQ-9, brief STAI, and single-item academic burnout (IUBA).

Overall, 1265 students (74.2% female) completed the survey. Of them, 37.4% scored positive for depressive symptoms, as measured by the BDI-II, and more than half (53%) by the PHQ-9. Suicidal ideation was reported by about 12% whilst high levels of state and trait anxiety were informed by 28.8% and 29.4% of the students. The prevalence of burnout was 40.2%. Female and pre-clinical students reported significantly (p < 0.01) higher rates of depressive, anxiety, and burnout symptoms. Alcohol, energy drinks, and tobacco were the most frequently used substances. Total scores of self-reported mental health problems negatively correlated (p < 0.001) with objective academic results and positively correlated (p < 0.02) with the number of substances consumed in the last 30 days.

Research-based on self-reported data could favour information bias due to the social desirability effect and memory error.

A high prevalence of substance consumption and several mental health problems was found among medical students, especially females. The relevant influence of academic-related factors on students' well-being may be a call for medical schools to implement initiatives aimed to improve students' ability to detect, address, and seek help for their mental health issues.
