BACKGROUND
Despite their good intentions, people often do not eat healthily. This is known as the intention-behavior gap. Although the intention-behavior relationship is theorized as a within-person process, most evidence is based on between-person differences.
PURPOSE
The purpose of the present study is to investigate the within-person intention-behavior association for unhealthy snack consumption.
METHODS
Young adults (N = 45) participated in an intensive longitudinal study. They reported intentions and snack consumption five times daily for 7 days (n = 1068 observations analyzed).
RESULTS
A within-person unit difference in intentions was associated with a halving of the number of unhealthy snacks consumed in the following 3 h (CI95 27-70 %). Between-person differences in average intentions did not predict unhealthy snack consumption.
CONCLUSIONS
Consistent with theory, the intention-behavior relation for healthy eating is best understood as a within-person process. Interventions to reduce unhealthy snacking should target times of day when intentions are weakest.
背景
尽管人们动机良好，但往往饮食不健康。这被称为意图 - 行为差距。虽然意图 - 行为关系在理论上被视为个体内部的过程，但大多数证据基于个体间差异。
目的
本研究旨在调查个体内部不健康零食消费的意图 - 行为关联。
方法
年轻人（N = 45）参与了一项密集纵向研究。他们在7天内每天报告5次意图和零食消费情况（共分析了n = 1068次观察结果）。
结果
意图上的个体内部单位差异与接下来3小时内不健康零食消费数量减半相关（95%置信区间为27% - 70%）。平均意图的个体间差异无法预测不健康零食消费情况。
结论
与理论一致，健康饮食的意图 - 行为关系最好理解为个体内部过程。减少不健康零食摄入的干预措施应针对意图最薄弱的时间段。
