Spreading the word: A process evaluation of a voluntary AOD prevention program

A Review of the Prevention of Drug Addiction: Specific Interventions, Effectiveness, and Important Topics

BACKGROUND

This study was a narrative review on prevention of addictive behaviors with an effort to clarify the major concepts of prevention and its dimensions.

METHODS

The PsycInfo and MedInfo databases were used to identify prevention. Α total of 65 articles were found 46 of which were included in the review. Τhe data were analyzed using content analysis.

FINDINGS

For a better understanding of the results, it was deemed advisable to categorize them into: (a) the types of major interventions and the theoretical approaches on which they were based, (b) the results of the review articles according to (1) variables and factors concerning the prevention proved important through the review and (2) a number of more general important topics which arose in the prevention of addictive behaviors.

CONCLUSION

The results highlighted the greater effectiveness of community-based programs, applied primarily in broader contexts but also secondarily in high-risk groups. Τhe results were discussed based on the combination of the emerged factors with each other and prevention experience.

Impact of Ethnic Composition on Mechanisms of Change in School-Based Substance Use Intervention Groups

Delivering alcohol use intervention services in the school setting represents a key approach to engaging youth of all backgrounds, particularly underserved populations, in such programming. Relative progress has been made toward implementing culturally responsive services for youth; however, little is known about the role of ethnic composition on group processes purported to underlie mechanisms of change. We examined associations between ethnic group composition and therapeutic processes within a voluntary, school-based alcohol use intervention at seven schools across three cities (N groups = 353). Ethnic composition was characterized as: group ethnic diversity on a continuum, group ethnic homogeneity (i.e., where at least 66% of participants shared the same ethnicity), and comparing groups where one of the three largest ethnicities in the sample reached the majority (i.e., African-American vs. Hispanic vs. non-Hispanic white). Ratings on group processes were obtained from participants (satisfaction; belonging), facilitators (empathy; rapport), and coders (engagement; responsiveness). Mixed-effects models revealed that students in groups with African-American and Hispanic majorities reported a higher sense of satisfaction compared to groups with non-Hispanic white majorities. Facilitators endorsed expressing empathy more frequently with majority African-American and Hispanic groups than with non-Hispanic white groups. Study findings highlight the importance of considering different dimensions of ethnic composition when examining mechanisms of change in group intervention research.
