The present study aimed to ascertain whether parental reports of their feeding practices are associated with independent observations of these behaviours, and whether the reliability of maternal report depends upon the child's weight.
A total of 56 mothers and their children ate a lunch to satiety which was videotaped and coded for maternal use of control during feeding. Mothers also completed questionnaires about their feeding practices and children were weighed and measured.
Maternal reports of controlling feeding practices were poorly related to independent observations of these behaviours in the laboratory. However, there was a significant interaction between child BMI z score and observed pressure to eat in predicting maternally reported pressure to eat. There was also a significant interaction between child BMI z score and observed maternal restriction with food in predicting maternally reported restriction. When decomposed, these interactions suggested that only mothers of relatively underweight children were accurate at reporting their use of pressure to eat when compared to independent observations. For mothers of relatively overweight children there was a significant negative relationship between observed and reported restriction over food.
Overall there was poor correspondence between maternal reports and independent observations of the use of controlling feeding practices. Further research is needed to replicate these findings and to ascertain whether parents who are inaccurate at reporting their use of these feeding practices are unaware that they are using controlling feeding practices or whether they are responding in socially desirable ways to questionnaires assessing their feeding behaviour.
本研究旨在确定父母对其喂养行为的报告是否与对这些行为的独立观察结果相关,以及母亲报告的可靠性是否取决于孩子的体重。
共有56位母亲及其孩子吃午餐直至饱腹,期间进行录像,并对母亲在喂养过程中的控制行为进行编码。母亲们还完成了关于其喂养行为的问卷,同时对孩子进行称重和测量。
母亲关于控制喂养行为的报告与在实验室中对这些行为的独立观察结果相关性较差。然而,在预测母亲报告的进食压力方面,孩子的BMI z评分与观察到的进食压力之间存在显著交互作用。在预测母亲报告的食物限制方面,孩子的BMI z评分与观察到的母亲食物限制之间也存在显著交互作用。分解这些交互作用后发现,与独立观察结果相比,只有相对体重不足孩子的母亲在报告其使用进食压力方面较为准确。对于相对超重孩子的母亲,观察到的和报告的食物限制之间存在显著的负相关关系。
总体而言,母亲报告与对控制喂养行为使用情况的独立观察结果之间的对应性较差。需要进一步研究来重复这些发现,并确定那些在报告其使用这些喂养行为时不准确的父母是不知道自己在使用控制喂养行为,还是他们以符合社会期望的方式回应评估其喂养行为的问卷。
