This pilot study evaluated effects of Lunch is in the Bag on behavioral constructs and their predictive relationship to lunch-packing behaviors of parents of young children.
Six child care centers were pair-matched and randomly assigned to intervention (n = 3) and comparison (n = 3) groups. Parent/child dyads participated. Constructs of knowledge, outcome expectations, perceived control, subjective norms, and intentions were measured by a pre/post questionnaire. Hierarchical linear regression was used, and P < .05 was considered significant.
There were significant increases in knowledge (P = .01); outcome expectations for whole grains (P < .001); and subjective norms for fruit (P = .002), vegetables (P = .046), and whole grains (P = .02). Perceived control, outcome expectations, and intentions significantly predicted packing vegetables and knowledge predicted whole grains.
Lunch is in the Bag is a feasible intervention to improve the lunch-packing behaviors of parents of preschool-aged children.
本初步研究评估了“Lunch is in the Bag”对行为结构的影响,及其对幼儿家长的午餐打包行为的预测关系。
将 6 家儿童保健中心进行配对,并随机分配到干预组(n=3)和对照组(n=3)。家长/儿童对子参与。通过预/后问卷调查衡量知识、结果预期、感知控制、主观规范和意图等结构。采用分层线性回归,P<.05 被认为具有统计学意义。
知识(P=.01)、全谷物的结果预期(P<.001)以及水果(P=.002)、蔬菜(P=.046)和全谷物(P=.02)的主观规范显著增加。感知控制、结果预期和意图显著预测了包装蔬菜的行为,而知识则预测了全谷物的行为。
“Lunch is in the Bag”是一种可行的干预措施,可以改善学龄前儿童家长的午餐打包行为。
