Integrating the theory of planned behaviour (TPB) with the five-factor model (FFM) of personality may provide insight into the cognitive and motivational mechanisms linking personality with health behaviour, but this issue has received very little attention regarding fruit consumption. Mediator effects of TPB concepts in the personality-fruit consumption link, as well as moderator effects of personality in the intention-fruit consumption link, were therefore investigated in the present study. Data on fruit consumption, TPB concepts and FFM dimensions were gathered among 405 respondents in face-to-face interviews using questionnaires. Structural equation modelling was used to investigate the mediator and moderator effects. The direct effect of conscientiousness on fruit consumption was mediated by attitude and perceived behavioural control, while no direct effect of neuroticism on fruit consumption was found. Neuroticism moderated the intention-fruit consumption relationship with the weakest relationship for those scoring high on neuroticism. Conscientiousness did not moderate the intention-fruit consumption relationship. TPB variables are mediators in the conscientiousness-fruit consumption link. Whether fruit consumption is intentional may be dependent upon the personality dimension neuroticism. Personality dimensions may be a useful addition to the TPB and should be considered in health behaviour change interventions.
将计划行为理论（TPB）与人格的五因素模型（FFM）相结合，可能有助于深入了解人格与健康行为之间的认知和动机机制，但关于水果消费，这一问题几乎没有得到关注。因此，本研究调查了 TPB 概念在人格-水果消费关系中的中介效应，以及人格在意图-水果消费关系中的调节效应。本研究使用问卷在面对面访谈中收集了 405 名受访者的水果消费、TPB 概念和 FFM 维度数据。使用结构方程模型来调查中介和调节效应。尽责性对水果消费的直接影响是由态度和感知行为控制介导的，而神经质对水果消费没有直接影响。神经质调节了意图-水果消费关系，对于神经质得分较高的人来说，这种关系最弱。尽责性并没有调节意图-水果消费关系。TPB 变量是尽责性-水果消费关系的中介。水果消费是否是有意的可能取决于神经质这一人格维度。人格维度可能是 TPB 的有用补充，应在健康行为改变干预中加以考虑。
