Many adults have poor dietary habits and few studies have focused on mechanisms underlying these behaviors. This study examined psychosocial determinants of dietary behavior change in university employes across a 5-month period. Participants completed measures of fruit and vegetable consumption (FVC) and low fat food consumption (LFC) and social cognitive constructs. Multiple regression analyses accounted for a unique proportion of variation in dietary change. Outcome expectations significantly predicted FVC and LFC. Self-efficacy significantly predicted LFC. Goals were not associated with dietary behaviors. Further research into implementation strategies may provide insight into how goals work to bring about change.
许多成年人饮食习惯不良,但很少有研究关注这些行为背后的机制。本研究在 5 个月的时间里,调查了大学生员工饮食行为改变的社会心理决定因素。参与者完成了水果和蔬菜摄入量(FVC)和低脂肪食物摄入量(LFC)以及社会认知结构的测量。多元回归分析解释了饮食变化的独特比例。结果期望显著预测了 FVC 和 LFC。自我效能感显著预测了 LFC。目标与饮食行为无关。进一步研究实施策略可能有助于了解目标如何发挥作用以实现改变。
