Latent Transition Analysis for Adolescent Substance Use Onset Across Ethnic Groups

A chapter by Linda M. Collins of Pennsylvania State University introduces latent transition analysis (LTA) for substance use prevention research. The technique models stage-sequential substance use onset, estimating transition probabilities between stages of use. The method is applied to evaluate prevention program effectiveness separately for Anglo, Latino, and Asian-American adolescents measured in seventh and eighth grades.

Use Cases

• Evaluating prevention program effectiveness by comparing transition probability matrices between treatment and control groups.
• Modeling stage-sequential substance use onset processes based on latent transition analysis parameters.
• Analyzing ethnic differences in substance use trajectories among adolescents.
• Assessing intervention timing and booster effects tailored to specific ethnic groups.

Strengths

• Methodology is described in detail by an author from Pennsylvania State University.
• Analysis is applied to three distinct ethnic groups (Anglo, Latino, Asian-American).
• Data likely contains longitudinal measurements from seventh and eighth grades.

Limitations

• The actual dataset, including columns and rows, is unavailable for inspection.
• Row count and data scale are unknown, limiting suitability assessment.
• License is closed, restricting access and reuse.
