The purposes of this study were to cross-culturally translate and adapt the Thai version of the Adolescent Drinking Media Literacy Scale (Thai-DMLS) and to conduct psychometric testing of the Thai-DMLS, including its assessment of construct validity and reliability. This study comprised two distinct phases: a cross-cultural translation process, and a two-wave data collection to assess the psychometric properties of the Thai-DMLS, involving 343 secondary school students in Chiang Mai, Thailand. Exploratory factor analysis was performed to evaluate the construct validity of the Thai-DMLS using data from the first wave. Subsequently, confirmatory factor analysis was undertaken with data from the subsequent wave, which was administered two weeks later. Cronbach’s alpha coefficient was calculated to evaluate the internal reliability of the Thai-DMLS, while the scale’s external reliability was assessed using intra-class correlations.

            The results revealed that the 18 items of the Thai-DMLS were categorized into two factors, including 1) knowing the truth about alcohol business marketing strategies and 2) critical thinking about media strategies and unrevealed fact. The results from confirmatory factor analysis indicated the good fit of the measurement model (X2/df = 1.81, RMSEA = 0.05, CFI = 0.95, TLI =0.94). The Cronbach’s alpha coefficients for each factor were 0.82 and 0.92, respectively. Intra-class correlations for each factor were 0.95 and 0.97, respectively. The findings suggest that the Thai-DMLS exhibits good validity and reliability. It is recommended that healthcare providers and researchers consider using this scale to evaluate the levels of media literacy related to drinking among adolescents, as it serves as a foundational step in the implementation of future health promotion initiatives.
