The multifactorial nature of cardiovascular disease means that preventive efforts often stress a variety of complex behavioural capabilities (eg, increasing physical activity, changing eating habits, quitting smoking, practising stress reduction techniques). A variety of theoretical models have been suggested to help explain and predict health behaviours; however, social cognitive theory provides one of the most comprehensive frameworks for understanding human behaviour. Important constructs of social cognitive theory that relate to the initiation and maintenance of behaviour change are reviewed here, including perceived threat, behavioural capability, expectancies, interdependence and environmental influence. Suggestions about how these constructs may be applied in health practice are provided.
心血管疾病的多因素性质意味着预防措施通常强调多种复杂的行为能力（例如，增加体育活动、改变饮食习惯、戒烟、练习减压技巧）。人们提出了各种理论模型来帮助解释和预测健康行为；然而，社会认知理论为理解人类行为提供了最全面的框架之一。本文回顾了社会认知理论中与行为改变的启动和维持相关的重要概念，包括感知威胁、行为能力、期望、相互依存和环境影响。并就如何将这些概念应用于健康实践提出了建议。
