Our previous work found that perceived control over life was a significant predictor of the quality of diet of women of lower educational attainment. In this paper, we explore the influence on quality of diet of a range of psychological and social factors identified during focus group discussions, and specify the way this differs in women of lower and higher educational attainment. We assessed educational attainment, quality of diet, and psycho-social factors in 378 women attending Sure Start Children's Centres and baby clinics in Southampton, UK. Multiple-group path analysis showed that in women of lower educational attainment, the effect of general self-efficacy on quality of diet was mediated through perceptions of control and through food involvement, but that there were also direct effects of social support for healthy eating and having positive outcome expectancies. There was no effect of self-efficacy, perceived control or outcome expectancies on the quality of diet of women of higher educational attainment, though having more social support and food involvement were associated with improved quality of diet in these women. Our analysis confirms our hypothesis that control-related factors are more important in determining dietary quality in women of lower educational attainment than in women of higher educational attainment.
我们之前的工作发现,对生活的控制感是低教育程度女性饮食质量的重要预测因素。在本文中,我们探讨了一系列在焦点小组讨论中确定的心理和社会因素对饮食质量的影响,并具体说明了这些因素在低教育程度和高教育程度女性中的差异。我们评估了英国南安普顿的 Sure Start 儿童中心和婴儿诊所的 378 名女性的教育程度、饮食质量和心理社会因素。多组路径分析表明,在教育程度较低的女性中,一般自我效能感对饮食质量的影响是通过控制感和食物参与感来介导的,但健康饮食的社会支持和积极的结果预期也有直接影响。自我效能感、控制感和结果预期对教育程度较高的女性的饮食质量没有影响,尽管这些女性拥有更多的社会支持和食物参与度与饮食质量的提高有关。我们的分析证实了我们的假设,即与控制相关的因素在决定低教育程度女性的饮食质量方面比高教育程度女性更为重要。
