Prevalence of depressive symptoms and depression literacy (D-Lit) among Saudi postgraduate students

Abstract

The prevalence of any disorders listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) is 34.2% in Saudi Arabia over the course of a person's lifetime. Young Saudis are more likely to develop major depressive disorder than older Saudis. Globally, postgraduate students are more vulnerable to developing depression compared to the general population. According to a national study carried out in Saudi Arabia, a small proportion of individuals experiencing psychiatric disorders over a period of 12 months receive any kind of treatment. This highlights the importance of community education aimed at enhancing mental health awareness. A web-based Arabic cross-sectional survey was conducted among Saudi postgraduate students from October 2019 to August 2020. The survey included questions related to sociodemographic characteristics, sources of information, depression literacy (D-Lit), the Patient Health Questionnaire-9 (PHQ-9) for depression, and the participants’ attitudes toward depression. A total of 517 participants took part in the survey, with 46% of them screened positive for depression. The mean D-Lit score was 10.65, which was lower than that reported in studies conducted among medical students and hospital staff. No significant differences were found in D-Lit scores across all sociodemographic characteristics, except for gender and specialty (p = 0.002 and <0.001, respectively). The Internet, awareness posters, a doctor (previously diagnosed with depression), and awareness activities related to depression showed significant differences in the mean score of D-Lit (p < 0.001, 0.005, < 0.001, and < 0.001, respectively). In Saudi Arabia, this study found that postgraduate students have a notably higher occurrence of depression compared to the general population. However, despite their higher educational level, these students lacked sufficient awareness and understanding of depression to recognize it and seek help. Consequently, it is important to initiate awareness campaigns aimed at enhancing the mental well-being of postgraduate student
