Mental health conditions among youths are increasing rapidly, taking into consideration their biological, psychological and social development in the time of technological advancement with its associated challenges. Therefore, this study examined the psychometric properties of eight mental health scales among Ghanaian youth. A total of 708 youths (62.1% females; 10–29 years) from junior high schools, senior high schools and a university were recruited to respond to measures on depression, anxiety, somatic symptoms, obsessive–compulsive symptoms, insomnia, smartphone application-based addiction, internet addiction, life satisfaction, stress and cognitive fatigue. Confirmatory factor analysis (CFA) and Pearson’s r were used to analyse the data. The findings indicated acceptable CFA fit for all scales (comparative fit index [CFI] >0.9, Tucker–Lewis index [TLI] >0.9, root mean square error of approximation [RMSEA] <0.08 and standardized root mean square residual [SRMR] <0.08), and internal reliability was satisfactory (Cronbach’s α = 0.774–0.868 and McDonald’s ω = 0.775–0.870). Correlation analyses showed significant relationships between all the measures except for life satisfaction and internet addiction, and stress and life satisfaction. Both the CFA indices and correlation analyses indicate that all the mental health measures demonstrate acceptable initial evidence of reliability and construct validity.
