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.
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.
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.
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.
保护行为策略量表（PBSS-20）是用于衡量参与保护行为策略（PBS）的常用工具之一。本研究旨在检验 PBSS-20 的法德版本在瑞士大样本年轻男性中的心理测量特性。
该样本包括参加瑞士物质使用风险因素队列研究的 5017 名年轻男性（平均年龄=25.44 岁）。使用第二次随访评估中的 PBS 使用、每周总饮酒量和酒精相关后果的测量方法。
对先前文献中记录的不同模型进行验证性因素分析提供了对四因素模型的初步支持。拟合统计数据表明，该模型充分反映了数据的结构。进一步的研究结果还为该四因素模型的内部一致性和收敛效度提供了支持，而在语言区域之间仅显示出度量不变性而非标度不变性。
尽管需要进一步研究来检验语言区域和性别之间的测量不变性，但目前的研究结果表明，法德版的 PBSS-20 是可靠的，它可能是一种有前途的研究和临床工具，可以在说法语和德语的国家使用。
