This study aimed to prospectively examine the explanatory value of the protection motivation theory (PMT) for the intention to use manner of drinking protective behavioral strategies (MD PBS) and to explore its invariance across genders.
A targeted sampling procedure was used to recruit 339 young adults in the community (Mage = 21.1; SD = 2.21; female = 50.7%) who completed baseline and 2-month follow-up measures of the PMT constructs and intentions to use each of the five MD PBS.
Regression analyses revealed that the coping appraisal components (response efficacy and self-efficacy) had greater explanatory power for the intention to use MD PBS than the threat appraisal components (perceived vulnerability and perceived severity). Perceived vulnerability to alcohol consequences was not prospectively associated with any specific behavioral intention or with the total MD PBS score. In contrast, perceived severity was prospectively associated with the intention to use three out of five PBS and the total MD score. Regression coefficients revealed gender invariance for all six models.
Our findings suggest that interventions aimed at encouraging young adults to use alcohol MD PBS would be most effective if they included components that enhance self-efficacy in using these strategies and emphasize their perceived usefulness in reducing alcohol-related consequences.
本研究旨在前瞻性检验保护动机理论（PMT）对使用饮酒保护行为策略（MD PBS）意图的解释价值，并探讨其在性别上的不变性。
采用目标抽样程序招募了 339 名社区中的年轻成年人（Mage=21.1；SD=2.21；女性=50.7%），他们完成了 PMT 结构和使用五种 MD PBS 中每一种的意图的基线和 2 个月的随访测量。
回归分析显示，应对评估成分（反应效能和自我效能）对 MD PBS 使用意图的解释力大于威胁评估成分（感知脆弱性和感知严重性）。感知到酒精后果的脆弱性与任何特定的行为意图或与 MD PBS 总分均无前瞻性关联。相比之下，感知严重性与使用五种 PBS 中的三种和 MD 总分的意图有前瞻性关联。回归系数显示所有六个模型的性别不变性。
我们的研究结果表明，如果旨在鼓励年轻人使用饮酒 MD PBS 的干预措施包括增强使用这些策略的自我效能的成分，并强调它们在减少与酒精相关的后果方面的有用性，那么这些干预措施将最为有效。
