This study aims to examine the subtypes of problematic alcohol use among ROK officers and non-commissioned officers(NCOs) and investigated the relationships between problematic alcohol use patterns and suicide risk variables. This research adopted a person-centered approach using latent profile analysis to understand the heterogeneity of individual response patterns on alcohol use which was undetected in variable-centered analyses. The problematic alcohol use group was selected based on the score of the alcohol addiction questionnaire in the Service Adaptation Inventory for officers and NCOs. The result of the latent profile analysis indicated that there were four latent profiles(α1, α2, β1, β2). Except for α1 profile, the other three profiles showed the risk of suicide ideation and suicide intention. These findings will be helpful in designing for mental health policies for ROK Officers and NCOs.
