Use of the WHO's Perceived Well-Being Index (WHO-5) as an efficient and potentially valid screen for depression in a low income country.

Abstract

Introduction: Depression is associated with negative social, economic, and family outcomes and the majority of individuals with depression in low and middle income countries (LMICs) are untreated. A critical first step in bridging the treatment gap is accurate, feasible, and culturally appropriate screening to identify those who need treatment. The WHO's Perceived Well-Being Index (WHO-5) well-being instrument can potentially meet the screening needs of LMICs in primary care and community-based settings. This study tested the feasibility and validity of this tool to identify depression among adult parents of young children in Addis Ababa, Ethiopia. Successful identification and treatment of depression in parents extends benefits to children and families. Method: The WHO-5 was translated to Amharic and administered to 849 adults and compared with simultaneous administration of the well-established PHQ-9 instrument. Feasibility was assessed and analyses evaluated frequency of positive screens for depression, internal consistency, sensitivity and specificity of the WHO-5, and sociodemographic correlates of depression. Results: The prevalence of probable depression was similar as assessed by the PHQ-9 (17.3%) and the WHO-5 (18.5%). The internal consistency of the WHO-5 was strong (Cronbach's alpha = .83). WHO-5 agreement with the PHQ-9 was moderate; sensitivity and specificity were strong. Correlates of depression included unemployment and financial status. Discussion: The study provides promising evidence to support use of the WHO-5 to identify depression in Ethiopia. Feasibility was good, and it was culturally and linguistically acceptable. The results suggest that minimally trained community health and education workers in countries like Ethiopia could use the WHO-5 effectively in primary health and education settings.
