Protective behavioral strategies (PBS) have shown utility in reducing alcohol-related negative consequences. The Protective Behavioral Strategies Scale (PBSS) is one of the most widely used and well-validated instruments for evaluating these strategies. However, a Spanish adaptation of this or any other measure of PBS is not available. We aimed to provide a Spanish version of PBSS-20 and examine its psychometric properties.
We recruited 538 undergraduate students from three Spanish universities (mean age = 21.2; females = 78%). Measures included the Spanish-PBSS-20 (S-PBSS-20), Young Adult Alcohol Consequences Questionnaire (YAACQ), Daily Drinking Questionnaire, and frequency of alcohol use, drunkenness, and binge drinking.
Our results support the use of the original 3-factor structure of the PBSS-20. Internal consistency reliability ranged between 0.71-0.77, and evidence of validity was provided according to the expected relationships with other variables. Exploratory factor analyses provided evidence of convergent/discriminant validity of S-PBSS-20.
The results suggest that PBSS-20 is a useful instrument for assessing protective behavioral strategies in alcohol users. The S-PBSS-20 could be useful for research on alcohol-related protective behavioral strategies and consequences, and could also inform the design of educational interventions for promoting the use of protective strategies and reducing alcohol-related negative consequences.
保护性行为策略（PBS）已被证明在减少与酒精相关的负面后果方面具有效用。保护性行为策略量表（PBSS）是评估这些策略的最广泛使用和最有效的工具之一。然而，目前还没有西班牙语版的 PBSS 或任何其他 PBS 测量工具。我们旨在提供 PBSS-20 的西班牙语版本，并检验其心理测量学特性。
我们从三所西班牙大学招募了 538 名大学生（平均年龄=21.2；女性=78%）。测量工具包括西班牙语版保护性行为策略量表（S-PBSS-20）、青年酒精后果问卷（YAACQ）、每日饮酒问卷和酒精使用频率、醉酒和狂饮频率。
我们的结果支持 PBSS-20 的原始 3 因素结构的使用。内部一致性信度在 0.71-0.77 之间，并且根据与其他变量的预期关系提供了有效性证据。探索性因素分析提供了 S-PBSS-20 的收敛/区分效度的证据。
结果表明，PBSS-20 是评估酒精使用者保护性行为策略的有用工具。S-PBSS-20 可用于与酒精相关的保护性行为策略和后果的研究，也可用于设计促进使用保护策略和减少与酒精相关的负面后果的教育干预措施。
