Dimensionality and psychometric analysis of an alcohol protective behavioral strategies scale

Abstract

Objective: The current study examined the dimensionality of a protective behavioral strategies (PBS) measure among undergraduate, predominantly freshmen (92.5%) college students reporting recent alcohol use (n = 320).

Method: Participants completed a web-based survey assessing 22 PBS items. Factor analyses determined the underlying factor structure of the items. Congruence of the factor structure among gender and racial sub-groups was examined by rotating the sub-groups' matrices via the Procrustes rotation method. Reliability analyses determined internal consistency. Results: A 2-factor solution was retained utilizing 17 of the original items. Both PBS sub-scales (Limits and Avoidance) had acceptable internal consistency across all samples.

Conclusions: This PBS Scale was determined to be bi-dimensional and reliable. The dimensions suggest two underlying foci: ways to limit alcohol intake and ways to avoid alcohol intake while socializing. Practical implications of these findings are discussed.
