Background
The Global Forum for Health Research, with the support of the World Health Organization, highlighted the need to prioritize mental health research in Africa. The introduction of revised descriptions of Posttraumatic Stress Disorder (PTSD) and Adjustment Disorder, along with new diagnoses of Complex PTSD and Prolonged Grief Disorder, in the ICD-11 creates a need for additional national-level epidemiological studies on the prevalence of stress-related disorders.
Methods
The prevalence rates of these four ICD-11 stress disorders were assessed in three African countries including Nigeria (N = 1006), Kenya (N = 1018), and Ghana (N = 500). Participants completed disorder-specific measures for each disorder. Findings: Across the entire sample, the current prevalence rate of probable Adjustment Disorder was 8.4% (95% C.I. = 7.4%, 9.6%), probable PTSD was 18.6% (95% C.I. = 17.2, 20.2%), probable Complex PTSD was 15.9% (95% C.I. = 14.5%, 17.4%) and probable Prolonged Grief Disorder was 3.7% (95% C.I. = 3.1%, 4.5%).
