Abstract

Objective

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.

Design

Participants (N = 121) were recruited to participate in a two-week study about daily experiences with exercise and alcohol (Mage = 30.93; SDage = 9.88; 59.2% female; 71.1% Caucasian).

Main Outcome Measures

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.

Results

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.

Conclusion

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.

使用计划行为理论预测酒精使用的潜在特征分析

摘要

客观的

目前的研究试图确定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)之间的关联程度不同的成年饮酒者亚组,并探讨不同的亚组概况是否相关两周后去酒精使用。

设计

参与者(N = 121)被招募参加一项为期两周的关于日常锻炼和饮酒体验的研究(M年龄= 30.93;SD年龄= 9.88;59.2% 女性;71.1% 高加索人)。

主要观察指标

酒精态度、主观规范、酒精拒绝自我效能和意图被用来创建班级成员。行为结果包括(1)饮酒频率,(2)饮酒量,和(3)饮酒醉酒。

结果

确定了两类饮酒者——第 1 类按所有结构的中等得分分类,而第 2 类按态度得分中等和在规范、酒精拒绝自我效能和意图方面的高分分类。类别名称与使用频率相关,但与使用量无关。

结论

目前的研究表明,在所有结构中得分中等的少数人应该接受仅关注 TPB 中包含的那些的干预工作,而绝大多数可能需要解决额外的结构。
