The relevance and reliability of the Strengths and Difficulties Questionnaire (SDQ) are insufficiently documented in Sub-Saharan populations. We examined the psychometric properties of the SDQ (parent version, SDQ-P) in a sample of 566 school-age children from the general population of semi-rural communities in Benin (West Africa). The SDQ items were administered in the local language (Fon) at 6 years of age. Cronbach’s alpha coefficients, Confirmatory Factorial Analyses and regression models including contextual characteristics documented internal and external validity of the scores. The median scores were 16 (IQR = [12-19] for the Total Difficulties, 7 [4–5] for the Internalizing and 9 [7–11] for the Externalizing behaviors. Moderate Cronbach’s alphas were observed (0.68 for the Total Difficulties and 0.65 for the Externalizing scores). The expected 3- and 5-factor structures of the SDQ were not replicated (best CFI = 0.72, 5 factors). However, consistent associations with gender, socioeconomic status, maternal depression and parental perception of behavioral difficulties supported the external validity of some SDQ scores. This first psychometric evaluation of the SDQ-P in Benin showed acceptable external validity, but poor internal consistency and factorial structure, suggesting cautious use and interpretation in future studies. Total Difficulties, Externalizing and Hyperactivity/Inattention scores appeared to be the most reliable.
