BACKGROUND
Motivation and self-regulation are two psychological systems that have been shown to be related to childhood obesity.
OBJECTIVE
This study evaluated independent and interactive associations of approach-oriented motivation (i.e., drive and reward responsiveness) and self-regulation (i.e., self-control and behavioral regulation) in relation to age- and sex-adjusted body mass index-z scores (BMI-z) in children.
METHODS
Children (55% female; M = 12.5 years ± .93) completed questionnaires assessing motivation and self-regulation, and anthropometric measurements were taken by research staff cross-sectionally.
RESULTS
Regressions revealed no independent associations of approach motivation or self-regulation and BMI-z. There were interactions between the drive facet of approach motivation, which assesses motivation to follow goals, and self-regulation in relation to BMI-z. Children with lower motivation to follow goals and lower self-regulation had higher BMI-z, and children with lower motivation to follow goals and higher self-regulation had lower BMI-z. Children with higher motivation to follow goals had similar BMI-z at all levels of self-regulation.
CONCLUSION
For children with low motivation to follow goals, self-regulation may be an important buffer of high BMI-z.
LEVEL OF EVIDENCE
Level V: cross-sectional descriptive study.
背景
动机和自我调节是两个已被证明与儿童肥胖相关的心理系统。
目的
本研究评估了与儿童年龄和性别调整后的体重指数Z评分（BMI-Z）相关的趋近导向动机（即驱力和奖励反应性）和自我调节（即自我控制和行为调节）的独立及交互关联。
方法
儿童（55%为女性；平均年龄 = 12.5岁±0.93）完成了评估动机和自我调节的问卷，研究人员进行了横断面人体测量。
结果
回归分析显示，趋近动机或自我调节与BMI-Z之间无独立关联。评估追求目标动机的趋近动机的驱力维度与自我调节在BMI-Z方面存在交互作用。追求目标动机较低且自我调节能力较低的儿童BMI-Z较高，而追求目标动机较低但自我调节能力较高的儿童BMI-Z较低。在所有自我调节水平上，追求目标动机较高的儿童BMI-Z相似。
结论
对于追求目标动机较低的儿童，自我调节可能是高BMI-Z的重要缓冲因素。
