Introduction

Preventing adolescent alcohol use is an international public health priority. To further understand adolescent alcohol use, this study tested a model of adolescent intention to consume alcohol that incorporated multiple social systems influences.

Methods

Participants included 2529 Australian secondary school students (M_age = 14.20; 53.7% female). Participants completed a survey about risk and protective factors for alcohol use at individual, family, school and community levels. Structure Equation Modeling (path analysis) was used to evaluate an extended Theory of Planned Behavior (TPB) that incorporated social system determinants of intention to consume alcohol.

Results

The final model explained 60% of the variance in adolescent alcohol use intention. All TPB constructs correlated with intention and experience of lifetime alcohol use. More exposure to information about alcohol use had a weak but significant influence on adolescents’ stronger perceived behavioral control. Having less friends who use alcohol, stricter parental rules for adolescent alcohol use, and unfavorable parent attitudes towards alcohol use, were associated with stronger adolescent anti-alcohol attitudes and subjective norms. Community level pro-abstinence attitudes predicted unfavorable adolescent attitudes to alcohol and intention to consume alcohol. Parental rules showed significantly stronger influences on alcohol use intention amongst younger adolescents.

Conclusions

Key social systems around adolescents significantly predicted intention to consume alcohol, and the extended TPB model explained the major variance in adolescent alcohol use. The findings emphasize the importance of multi-level approaches to the prevention of alcohol use. Situation-based factors that could trigger impulsive emotional response may be a future intervention focus.

澳大利亚青少年18岁之前的饮酒和饮酒意图：计划行为的扩展理论。

介绍

预防青少年饮酒是国际公共卫生的重中之重。为了进一步了解青少年饮酒，本研究测试了一种青少年饮酒意愿模型，该模型纳入了多种社会系统影响。

方法

与会者包括2529名澳大利亚中学生（中号_年龄= 14.20; 53.7％为女性）。参与者完成了有关个人，家庭，学校和社区各级饮酒风险和保护因素的调查。结构方程模型（路径分析）用于评估扩展的计划行为理论（TPB），该理论纳入了饮酒意图的社会系统决定因素。

结果

最终模型解释了青少年饮酒意图的60％变化。所有TPB构造均与终身饮酒的意图和经验相关。更多地了解与饮酒有关的信息，对青少年更强的感知行为控制产生了微弱但重要的影响。少喝酒的朋友，更严格的父母对青少年饮酒的规定以及父母对饮酒的不利态度都与更强的青少年反饮酒态度和主观规范相关。社区一级的节欲态度预示着青少年对饮酒和饮酒意愿的不良态度。父母的规定显示，青少年对饮酒意愿的影响明显更大。
