The aim of this study was to investigate whether the theory of planned behaviour (TPB) with the addition of risk awareness could predict breakfast consumption in a sample of adolescents from the UK and Australia. It was hypothesised that the TPB variables of attitudes, subjective norm and perceived behavioural control (PBC) would significantly predict intentions, and that inclusion of risk perception would increase the proportion of variance explained. Secondly it was hypothesised that intention and PBC would predict behaviour. Participants were recruited from secondary schools in Australia and the UK. A total of 613 participants completed the study (448 females, 165 males; mean=14years ±1.1). The TPB predicted 42.2% of the variance in intentions to eat breakfast. All variables significantly predicted intention with PBC as the strongest component. The addition of risk made a small but significant contribution to the prediction of intention. Together intention and PBC predicted 57.8% of the variance in breakfast consumption.
本研究旨在探讨在英国和澳大利亚青少年样本中，加入风险意识的计划行为理论（TPB）是否可以预测早餐消费。研究假设 TPB 的态度、主观规范和感知行为控制（PBC）变量将显著预测意图，并且纳入风险感知将增加可解释方差的比例。其次，研究假设意图和 PBC 将预测行为。参与者从澳大利亚和英国的中学招募。共有 613 名参与者完成了研究（448 名女性，165 名男性；平均年龄=14 岁±1.1）。TPB 预测了吃早餐的意图的 42.2%的变化。所有变量都显著预测了意图，其中 PBC 是最强的组成部分。风险的加入对意图的预测有很小但显著的贡献。一起，意图和 PBC 预测了早餐消费的 57.8%的变化。
