The current study sought to identify subgroups of adult drinkers who differ in their level of association between alcohol-related Theory of Planned Behavior (TPB) constructs (attitudes, perceived norms, self-efficacy, and intentions), and explore if distinct subgroup profiles relate to alcohol use two weeks later.
Participants (N = 121) were recruited to participate in a two-week study about daily experiences with exercise and alcohol ( = 30.93; = 9.88; 59.2% female; 71.1% Caucasian).
Alcohol attitudes, subjective norms, alcohol refusal self-efficacy, and intentions were used to create class membership. Behavioral outcomes included (1) drinking frequency, (2) drinking quantity, and (3) drinking to get drunk.
Two classes of drinkers were determined - Class 1 was categorized by moderate scores on all constructs, whereas Class 2 was categorized by moderate scores on attitudes and high scores on norms, alcohol refusal self-efficacy, and intentions. Class designation was associated with frequency, but not quantity of use.
The current study suggests that a minority of individuals who score moderately across all constructs should receive intervention efforts that focus on just those included in the TPB, while the vast majority may require additional constructs to be addressed.
本研究旨在识别成人饮酒者的亚组，这些亚组在与酒精相关的计划行为理论（TPB）结构（态度、感知规范、自我效能和意图）之间的关联程度上存在差异，并探讨不同的亚组特征是否与两周后的饮酒行为有关。
招募参与者（N=121）参加一项为期两周的关于日常锻炼和饮酒经历的研究（年龄：30.93 岁；标准差：9.88；女性占 59.2%；白种人占 71.1%）。
使用酒精态度、主观规范、拒绝饮酒的自我效能和意图来确定类别成员。行为结果包括（1）饮酒频率、（2）饮酒量和（3）饮酒至醉酒。
确定了两类饮酒者 - 第 1 类被归类为所有结构的得分均为中等，而第 2 类被归类为态度得分中等且规范、拒绝饮酒的自我效能和意图得分较高。类别指定与频率有关，但与使用量无关。
本研究表明，少数在所有结构上得分中等的个体应接受干预措施，重点关注 TPB 中包含的结构，而绝大多数个体可能需要解决其他结构。
