Objective: We assessed the validity of the Center for Epidemiological Studies Depression Scale for Children (CES-DC) as a screen for depression in Rwandan children and adolescents. Although the CES-DC is widely used for depression screening in high-income countries, its validity in low-income and culturally diverse settings, including sub-Saharan Africa, is unknown. Method: The CES-DC was selected based on alignment with local expressions of depression-like problems in Rwandan children and adolescents. To examine criterion validity, we compared CES-DC scores to depression diagnoses on a structured diagnostic interview, the Mini International Neuropsychiatric Interview for Children (MINI KID), in a sample of 367 Rwandan children and adolescents aged 10 through 17 years. Caregiver and child or adolescent self-reports endorsing the presence of local depression-like problems "agahinda kenshi" (persistent sorrow) and "kwiheba" (severe hopelessness) were also examined for agreement with MINI KID diagnosis. Results: The CES-DC exhibited good internal reliability (alpha = 0.86) and test-retest reliability (r = 0.85). The area under the receiver operating characteristic curve for the CES-DC was 0.825 when compared to MINI KID diagnoses, indicating a strong ability to distinguish between depressed and nondepressed children and adolescents in Rwanda. A cut point of equal to or greater than 30 corresponded with a sensitivity of 81.9% and a specificity of 71.9% in this referred sample. MINI KID diagnosis was well aligned with local expressions of depression-like problems. Conclusion: The CES-DC demonstrates good psychometric properties for clinical screening and evaluation in Rwanda, and should be considered for use in this and other low-resource settings. Population samples are needed to determine a generalizable cut point in nonreferred samples. (Contains 3 tables and 2 figures.)
