Overview

Randomized trial evaluates protective behavioral strategies for safe drinking in college students, suggesting improvements for measurement.

Key Points

  • This study aims to evaluate the psychometric properties of the PBSS-20 in college students, focusing on its applicability to both sexual and non-sexual minorities.
  • Participants included 1,730 college students from 12 universities.
  • Exploratory structural equation modeling (ESEM) and bifactor ESEM were used to assess the factor structure of PBSS-20.
  • Invariance testing was conducted to compare factor structures between sexual and non-sexual minority students.
  • The PBSS-20 showed an adequate model fit supporting the hypothesized factor structure.
  • Both total and subscale scores were negatively correlated with hazardous alcohol use measures.
  • The factor structure was similar for sexual and non-sexual minority students, indicating generalizability.
