Given the high prevalence of mental health (MH) and substance abuse problems in low-to-middle income countries, the scarcity of MH professionals, and the negative impact of psychiatric disorders on caregivers of young children, there is significant need for brief evidence-based screening tools for lay counselors to assist with MH assessment. This study aimed to validate a brief screening tool to assess psychiatric and substance use disorders, Client Diagnostic Questionnaire (CDQ), in South Africa (SA). Data are from a longitudinal study of health and psychosocial needs in preschool children in SA. Participants included 322 Zulu-speaking, female caregivers. Following procedures of the US CDQ validation study, lay counselors interviewed participants using the translated Zulu CDQ. Subsequently a psychologist conducted a full psychiatric assessment guided by the CDQ questions. Analyses examined sensitivity, specificity, and overall accuracy, comparing lay counselor and psychologist assessment. Sensitivity (73%), specificity (81%), and overall accuracy (79%) were good for the variable indicating presence of “any diagnosis.” Among those cases identified by the psychologist as having any psychiatric diagnosis, over 70% were correctly identified by lay counselors using the CDQ (i.e., positive predictive value was greater than 70%). The false positive rate was relatively low (19%). Specificity for “any disorder” (including substance use) and “any psychiatric disorder” were 81% and 79%. The isiZulu CDQ is a sensitive and valid MH diagnostic screener that can be used by lay counselors with limited MH training to identify those in need of treatment and target extremely scarce MH professionals.
