Substance Use, Family Functionality, and Mental Health among College Students in Spain.

Mental health symptoms are overrepresented among college students worldwide. The current research investigates the associations among substance use, family functionality, and mental health (depression, anxiety, and stress) among college students in Spain. A total of 828 (59.2% female and 40.8% male) college students from two public universities completed a self-reported online survey that included items on demographic information, substance use (alcohol, tobacco, cannabis, cocaine, prescription sedatives, and recreational sedatives), mental health symptoms (using the DASS-21 questionnaire) and family functionality (using the APGAR questionnaire). College students reporting substance use (especially recreational sedatives) and family dysfunctionality were more likely to exhibit symptoms of depression, anxiety and stress. These findings provide support for the underlying role of substance use and family functionality on mental health symptoms. Treatments targeting depression, anxiety, and stress among college students in Spain should aim to reduce substance use by and increase family support of students.
