最近的证据表明，大量大学生既过量饮酒，又吸食大麻。我们设计这项研究是为了测试计划行为扩展理论（TPB）预测酒精和大麻使用的能力。该研究的主要焦点是感知控制的问题，特别是控制信念的测量，以及自我效能和“对行为的感知控制”之间的区别。176名学生完成了TPB问卷调查，其中69%的学生在一周后成功联系上并提供行为数据。研究结果为TPB作为酒精和大麻使用意图和行为的预测因子提供了支持，尽管对信念成分的分析表明，乘法组合并不总是最佳的。来自验证性因素分析、潜在控制信念和对两种行为的差异预测的证据为改进的感知控制成分提供了支持。该研究还发现……
Recent evidence has suggested that large numbers of university students both consume excessive quantities of alcohol and use cannabis. We designed this study to test the ability of an extended theory of planned behavior (TPB) to predict alcohol and cannabis use. The main focus of the study was the issue of perceived control, particularly the measurement of control beliefs, and the proposed distinction between self-efficacy and "perceived control over behavior." One hundred seventy-six students completed TPB questionnaires, 69% of whom were successfully contacted 1 week later to provide behavioral data. Findings provided support for the TPB as a predictor of alcohol- and cannabis-use intentions and behavior, although analysis of belief components showed that a multiplicative combination is not always optimal. Evidence from confirmatory factor analyses, underlying control beliefs, and differential prediction of the two behaviors provided support for the refined perceived control components. The study also p...
