Standard prevention messages often fail because they do not account for the wide variation in how adolescents think and feel about [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/). Sequencing messages to match individual attitudes and social norms may improve engagement and receptivity among at-risk youth. ### #26 A Rebuttal-Based Social Norms-Tailored Cannabis Intervention for At-Risk Adolescents. **Citation:** Donaldson Candice D et al. *A Rebuttal-Based Social Norms-Tailored Cannabis Intervention for At-Risk Adolescents.* Prevention science: the official journal of the Society for Prevention Research. 2021.

The current studies evaluated the impact of a sequential multiple message approach tailored to the usage norms of adolescents expressing negative attitudes toward a cannabis prevention appeal. A multiple-message strategy was implemented-initial unfavorable message evaluations were invalidated using attitudinal rebuttal feedback prior to presenting a third tailored communication. Participants were cannabis-abstinent middle and high school students (ages 11 to 16). Study 1 (N = 808) compared effects of gain- and loss-framed messages tailored to each student’s normative usage perceptions. In Study 2 (N = 391), students were randomly assigned to receive a tailored or non-tailored message after receiving feedback meant to destabilize anti-message attitudes. For at-risk adolescents in Study 1 who perceived [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) as normative, a tailored gain-framed message resulted in the lowest usage intentions (p < .05). In Study 2, a conditional multiple-moderated mediation model showed that for high-risk teens with normative beliefs and pro-cannabis attitudes, exposure to a tailored gain-framed communication was associated with decreased cannabis attitude certainty, and lower usage intentions 2 months later (p < .05). Findings have implications for sequential messaging utilization in mass media campaigns and support the efficacy of tailored messages over a one-size-fits-all media approach. Further, results suggest that systematically weakening resistance to persuasive communications and tailoring messages consistent with individually perceived peer norms is an effective prevention strategy.  |   |  Further Reading Cannabis News[Study Published in Pediatrics Finds Infrequent Cannabis Use Can Impact Adolescent …](https://cedclinic.com/study-published-in-pediatrics-finds-infrequent-cannabis-use-can-impact-adolescent/) CED Clinic Blog[Adolescent Cannabis Use and Psychosis Risk: What This Cohort Study Shows and What It Does Not](https://cedclinic.com/adolescent-cannabis-psychiatric-outcomes-2026-digest/) Cannabis Memes[College is hard lmao](https://cedclinic.com/college-is-hard-lmao/) Further Reading CED Clinic Blog[Adolescent Cannabis Use and Psychosis Risk: What This Cohort Study Shows and What It Does Not](https://cedclinic.com/adolescent-cannabis-psychiatric-outcomes-2026-digest/) CED Clinic Blog[More Research on Adolescent Cannabis Use and Mental Disorders](https://cedclinic.com/adolescent-cannabis-use-and-anxiety-research/) CED Clinic Blog[Why Cannabis Works](https://cedclinic.com/why-cannabis-works/) [View on PubMed ↗](https://pubmed.ncbi.nlm.nih.gov/33791930/)[Full Text ↗](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8257086/)[DOI ↗](https://doi.org/10.1007/s11121-021-01224-9) [https://cedclinic.com/contact/](https://cedclinic.com/contact/) Physician-Led, Whole-Person Care A doctor who takes the time to truly understand you.
