Conclusions
The findings could not provide any empirical evidence to support the effectiveness of the studied intervention, APMaT, in changing alcohol use among employees within the current observation time. The effectiveness of APMaT might therefore be promising with a lengthier follow-up period. However, considering the complexity of delivering a prevention program in a dynamic workplace context, processes in the implementation of the program should be explored further. Despite the results in the present study, APMaT might be effective in other contexts if different delivery and implementation strategies were employed, or with a lengthier follow-up. While co-creation is the ambition of APMaT, employees were not engaged in the co-creation of the organizational alcohol policy or its enforcement. Prospective workplace prevention programs with similar objectives should increase the involvement of other actors within the organization beyond the management team while considering the organizational norms and culture in the early stages of co-creation.
