Eating a diet that is high in vitamins and low in fat is considered to be governed by social-cognitive factors, such as intentions, planning, self-efficacy, and outcome expectancies.
A longitudinal field study was designed to examine the interrelationships of these factors with dietary behaviors.
In 697 South Korean men and women, objective health-risk status was assessed at Time 1 (cholesterol, blood pressure, and body mass index) in conjunction with self-efficacy, outcome expectancies, and intentions. At Time 2, six months later, coping self-efficacy, planning, and dietary behaviors were measured. A two-group structural equation model for men and women was specified to determine the relations of distal and proximal predictors of a healthy diet.
Self-efficacy was of equal predictive power in men and women, whereas intentions and planning were relevant only in women. Objective risk status was associated with intentions in women but not in men.
Results confirm the predictive power of the Health Action Process Approach and point to the role of gender in the self-regulation of dietary behaviors.
人们认为，食用富含维生素且低脂的饮食受社会认知因素的支配，如意图、计划、自我效能感和结果期望。
设计一项纵向实地研究，以检验这些因素与饮食行为之间的相互关系。
对697名韩国男性和女性进行研究，在第1阶段评估客观健康风险状况（胆固醇、血压和体重指数），同时评估自我效能感、结果期望和意图。6个月后的第2阶段，测量应对自我效能感、计划和饮食行为。构建了一个针对男性和女性的两组结构方程模型，以确定健康饮食的远端和近端预测因素之间的关系。
自我效能感在男性和女性中具有同等的预测能力，而意图和计划仅与女性相关。客观风险状况与女性的意图相关，但与男性无关。
研究结果证实了健康行动过程方法的预测能力，并指出了性别在饮食行为自我调节中的作用。
