Sensitivity and specificity of the Akena Visual Depression Inventory (AViDI-18) in Kampala (Uganda) and Cape Town (South Africa).

Abstract

Visual scales may be particularly useful in screening for depression in patients with low literacy. However, few have been validated and none are in common use.AimModification and validation of a visual scale to screen for depression in low literacy settings. We assessed the validity, reliability and factor loading of a 28-item visual depression inventory using pictorial items depicting depression signs and symptoms. We validated a revised scale comprised of 18 items known as the Akena Visual Depression Inventory (AViDI-18) against a structured diagnostic interview (Mini-International Neuropsychiatric Inventory) in 343 patients in Kampala (Uganda) and Cape Town (South Africa). The 18 pictorial items had acceptable validity and reliability. The area under the curve (AUC) score of the AViDI-18 was 0.9. AUC scores were not significantly associated with sociodemographic variables. The AViDI-18 is a valid screen for depression in patients with low literacy.Declaration of interestNone.
