Flood stressors and mental distress among community-dwelling adults in Ghana: a mediation model of flood-risk perceptions

Abstract

Extant research has linked flooding with mental distress (MD) among flood-prone populations, but the mechanisms underlying this association remain largely unknown. This paper examines the association of flood stressors with MD among households in flood-prone communities in Ghana and estimates whether flood risk perceptions mediated the association. The study involved 767 household heads aged ≥20 years [mean = 47.3 ± 13.7); males = 61.4%]. Flood stressors were assessed using a 15-item Flood Stress-related Scale, while the Kessler Psychological Distress Scale (K10) was used to assess MD. Linear regression-based mediation analysis using Hayes’ PROCESS macro was performed to assess the indirect effect of flood stressors with MD through flood risk perceptions. After adjusting for potential confounders, flood stressors were significantly linked with higher risks of MD (β =.060-.080, p
