Pre-drinking, the practice of consuming alcohol prior to attending a subsequent event, increases the risk of alcohol-related harm, and is common in undergraduate student populations. The current study tested an integrated behaviour change model to identify the motivational, social-cognitive, and implicit predictors of pre-drinking.
University students (N = 289) completed an online questionnaire comprising measures of motivational and social-cognitive constructs related to reducing pre-drinking alcohol consumption and past behaviour, and an implicit association test for drinking identity. Participants reported their pre-drinking alcohol consumption at follow-up, 4 weeks from baseline.
Self-reported pre-drinking alcohol consumption.
A variance-based structural equation model revealed that few model hypotheses were supported. Although the effects of past behaviour, perceived behavioural control, and implicit drinking identity, on follow-up pre-drinking alcohol consumption were statistically significant, the effect of intention was not.
Current findings indicate pre-drinking alcohol consumption is associated with past behaviour, perceived behavioural control and implicit drinking identity, and no intentions to reduce pre-drinking alcohol consumption. The finding raise questions over the validity of applying the integrated model in this context. Interventions should consider these factors and attempt to facilitate the formation of intentions that lead to subsequent behaviour.
在参加后续活动之前饮酒（即“预饮”）会增加与酒精相关的伤害风险，这种行为在大学生群体中很常见。本研究采用整合行为改变模型，旨在确定预测预饮行为的动机、社会认知和内隐预测因子。
大学生（N=289）完成了一项在线问卷，其中包含与减少预饮酒精摄入量和过去行为相关的动机和社会认知结构的测量，以及饮酒身份的内隐联想测验。参与者在基线后 4 周时报告了他们的预饮酒精摄入量。
自我报告的预饮酒精摄入量。
基于方差的结构方程模型显示，很少有模型假设得到支持。尽管过去行为、感知行为控制和内隐饮酒身份对随访期间的预饮酒精摄入量的影响具有统计学意义，但意图的影响并不显著。
目前的研究结果表明，预饮酒精摄入量与过去行为、感知行为控制和内隐饮酒身份有关，而与减少预饮酒精摄入量的意图无关。这一发现引发了对在这种情况下应用整合模型的有效性的质疑。干预措施应考虑这些因素，并尝试促进形成随后行为的意图。
