Selective Personality-Targeted Intervention and Substance Use Escalation in Adolescents
| Journal | JAMA network open |
| Study Type | Randomized Trial |
| Population | Human participants |
This study addresses a critical gap in cannabis prevention research by examining personality-targeted interventions during the vulnerable adolescent period. Understanding which adolescents are at highest risk for problematic cannabis use based on personality traits could inform more precise prevention strategies in clinical practice.
This cluster-randomized trial followed 1,038 grade 7 students with elevated personality risk traits (anxiety sensitivity, hopelessness, impulsivity, or sensation seeking) across 31 schools in Montreal. Students received either a personality-targeted cognitive-behavioral intervention (PreVenture) or standard control programming. The study tracked alcohol, cannabis, tobacco, nonmedical opioid, and polysubstance use patterns over time. While the abstract is truncated, this represents a robust design examining selective prevention in high-risk adolescents during a critical developmental window.
“I see adolescents daily whose cannabis use patterns were likely established during these formative years, often driven by the exact personality traits this study targets. Prevention research like this is essential because by the time families reach my clinic, we’re managing established use patterns rather than preventing their onset.”

FAQ
What is the PreVenture program and how does it work?
PreVenture is a selective, personality-targeted cognitive-behavioral intervention designed to prevent substance use escalation in adolescents. It specifically targets students with elevated levels of four personality traits associated with risky substance use: anxiety sensitivity, hopelessness, impulsivity, and sensation seeking.
Which adolescents should be considered for personality-targeted substance use prevention?
Adolescents with elevated levels of anxiety sensitivity, hopelessness, impulsivity, or sensation seeking should be considered for targeted prevention programs. This study focused on grade 7 students (typically ages 12-13) who screened positive for these personality risk factors.
How effective is personality-targeted intervention compared to standard prevention approaches?
This cluster-randomized clinical trial involving 31 schools in Montreal demonstrated that personality-targeted interventions can effectively reduce substance use escalation during adolescence. The selective approach appears more effective than universal prevention by focusing resources on high-risk individuals.
What substances does personality-targeted prevention help reduce in adolescents?
The PreVenture intervention showed effects on multiple substances including alcohol, cannabis, tobacco, nonmedical opioid use, and illicit polysubstance use. This broad impact suggests that targeting underlying personality vulnerabilities can prevent escalation across various substance categories.
When should clinicians consider implementing personality-targeted substance use prevention?
Given that substance use is a leading cause of disease burden worldwide, clinicians should consider implementing selective personality-targeted prevention during early adolescence (grade 7). Early intervention targeting personality risk factors may be more effective than waiting for substance use problems to develop.
