This study applies three latent interaction models in the theory of planned behaviour (TPB; Ajzen, 1988, Attitudes, personality, and behavior. Homewood, IL: Dorsey Press; Ajzen, 1991, Organ. Behav. Hum. Decis. Process., 50, 179) to quitting smoking: (1) attitude × perceived behavioural control on intention; (2) subjective norms (SN) × attitude on intention; and (3) perceived behavioural control × intention on quitting behaviour.
The data derive from a longitudinal Internet survey of 939 smokers aged 15-74 over a period of 4 months. Latent interaction effects were estimated using the double-mean-centred unconstrained approach (Lin et al., 2010, Struct. Equ. Modeling, 17, 374) in LISREL.
Attitude × SN and attitude × perceived behavioural control both showed a significant interaction effect on intention. No significant interaction effect was found for perceived behavioural control × intention on quitting.
The latent interaction approach is a useful method for investigating specific conditions between TPB components in the context of quitting behaviour. Theoretical and practical implications of the results are discussed.
本研究将计划行为理论（TPB；阿杰恩，1988年，《态度、个性与行为》。伊利诺伊州霍姆伍德：多尔西出版社；阿杰恩，1991年，《组织行为与人类决策过程》，第50卷，第179页）中的三种潜在交互模型应用于戒烟：（1）态度×感知行为控制对戒烟意图的影响；（2）主观规范（SN）×态度对戒烟意图的影响；以及（3）感知行为控制×戒烟意图对戒烟行为的影响。
数据来自一项对939名年龄在15 - 74岁的吸烟者进行的为期4个月的纵向网络调查。使用LISREL中的双均值中心化无约束方法（林等人，2010年，《结构方程建模》，第17卷，第374页）估计潜在交互效应。
态度×主观规范和态度×感知行为控制对戒烟意图均显示出显著的交互效应。在戒烟行为方面，感知行为控制×戒烟意图未发现显著的交互效应。
潜在交互方法是研究戒烟行为背景下TPB各成分之间特定条件的有用方法。讨论了研究结果的理论和实际意义。
