Universal depressive symptom screening in middle schools in Istanbul: an epidemiologic study

Abstract

Introduction: Depression is a significant public health concern, with severe adolescent morbidity and mortality. Promoting adolescents' mental health is increasingly recognized, and schools are proposed as screening and preventive intervention sites. This cross-sectional study aimed to screen self-reported elevated depressive symptom prevalence among secondary school students in Istanbul, Turkey. The secondary objectives were determining behavioral problems, resilience, positive attitudes, and risk factors associated with depressive symptoms. Methods: Data collection was conducted between April–June 2022. Six thousand one hundred ten students from nine randomly selected schools from different city districts were approached. Depression was screened by the Centre for Epidemiological Studies Depression Scale for Children (CES-DC). The Strengths and Difficulties Questionnaire (SDQ) was used for screening behavioral problems and positive attitudes. Resilience was evaluated by the Child and Youth Resilience Measure (CYRM). Results: The final study sample comprised 2780 participants (response rate 47.7 %) with a mean age of 12.4 ± 1.1 years (females:52.7 %). Elevated depressive symptoms were detected in 31.2 % of the students. Female students exhibited higher scores in CES-DC and total difficulties but lower resilience scores in CYRM than male students. In a multiple regression analysis, female gender, higher total difficulties score, lower resilience score, and lower perceived academic performance significantly predicted CES-DC [F(6,2279) = 421, p < 0.01]. Discussion: Our findings showed high rates of elevated self-reported depressive symptoms in a city sample among Turkish adolescents at middle schools, in addition to coexisting behavioral difficulties and decreased resilience indicating poor psychosocial functioning. Given the prevalent depressive symptoms, screening and intervention programs involving resilience promotion may involve school systems to prevent adolescent depression.
