Abstract

Objective: The Protective Behavioral Strategies Scale (PBSS-20) is one of the most commonly used measures of engagement in protective behavioral strategies (PBS). This research aimed to examine the psychometric properties of a French and German version of the PBSS-20 in a large sample of young males in Switzerland.

Method: The sample included 5,017 young males (mean age = 25.44) participating in the Cohort Study on Substance Use Risk Factors in Switzerland. Measures of PBS use, total drinks per week, and alcohol-related consequences were used from a second follow-up assessment.

Results: Confirmatory factor analysis testing different models previously documented in the literature provided initial support for a four-factor model. Fit statistics indicated that this model adequately reflects the structure of data. Further findings also provided support for adequate internal consistency and for convergent validity of this four-factor model, whereas metric-but not scalar-measurement invariance across linguistic regions was demonstrated.

Conclusion: Although further research testing measurement invariance across linguistic regions and gender is warranted, results of the current study suggest that the French and German PBSS-20 is reliable and that it may represent a promising research and clinical tool that can be used in both French- and German-speaking countries.
