Facilitating Factors and Barriers to the Implementation of the Icelandic Prevention Model of Adolescent Substance Use in Chile: A Focus Group Study

Abstract

The use of alcohol and other drugs is a major public health problem in adolescence. The implementation of evidence-based prevention strategies is still scarce in the global south. This study aimed to evaluate facilitators and barriers to the implementation of the Icelandic prevention model of adolescent substance use (IPM) in Chile. We conducted a qualitative study of stakeholders during the implementation process of the IPM in six municipalities of the Metropolitan Region of Santiago, Chile. We convened six focus groups with parents and professionals from schools and municipal prevention teams (38 participants). Recordings were transcribed and submitted to a six-step thematic analysis. The following facilitators emerged: Participants valued the contribution of the IPM to articulate existing programs and teams, its community focus, and the local data obtained through the survey. There were also several barriers: Those included resistance to adopting a foreign model, the tension between generating local strategies and looking for measures to ensure the fidelity of the implementation, socioeconomic differences between and within municipalities, low-risk perception and supervision of parents in Chile, and a culture that generally does not discourage adolescent substance use. Implementation of the IPM was largely accepted by the stakeholders who agreed with the community approach of the model. The main barriers to consider were related to cultural and socioeconomic factors that need to be addressed in further research and may limit the effects of the model in Chile.
