Key result
Higher neuroticism scores were associated with increased odds of lifetime substance use (AOR 1.05; 95% CI 1.0-1.10; p=0.013), while higher agreeableness scores were associated with decreased odds.
Why the study?
Most substance use studies in low- and middle-income countries focus on the social environment domain rather than self-control mechanisms embedded within the person.

Among college students in Kenya, high neuroticism and low agreeableness are associated with a higher prevalence of substance use.
Kinyanjui et al. (2023) conducted a cross-sectional in Substance use (n=400). High neuroticism score vs. Lower neuroticism score was evaluated on Lifetime substance use (AOR 1.05, 95% CI 1.0-1.10, p=0.013). Higher neuroticism scores were associated with increased odds of lifetime substance use (AOR 1.05; 95% CI 1.0-1.10; p=0.013), while higher agreeableness scores were associated with decreased odds.
