Abstract

To examine Black emerging adult women's (ages 18-29) intention to meet the recommended daily intake of fruits and vegetables using the Theory of Planned Behavior (TPB). Black emerging adult women (BEAW; N = 100). A cross-sectional survey design. Hierarchical regression analyses revealed that in Model 1, attitudes (<.0001) and subjective norms (<.05) were significant predictors of intentions to meet the recommended daily intake of fruits and vegetables. In Model 2, attitudes (=.0001) and perceived behavioral control (<.0001) were revealed to be significant predictors of intentions. The change in R squared from Model 1 (R2=.304) and Model 2 (R2=.559), was 0.255 (F = 40.08, <.0001) with the addition of perceived behavioral control to the second model. The TPB may be a suitable framework to assess factors associated with fruit and vegetable intentions among BEAW. Interventions designed to increase fruit and vegetable intake in BEAW should prioritize modifying perceived behavioral control.

摘要

为了利用计划行为理论(TPB)来考察黑人成年初期女性(18-29 岁)达到推荐每日水果和蔬菜摄入量的意愿。黑人成年初期女性(BEAW;N=100)。采用横断面调查设计。分层回归分析显示,在模型 1 中,态度(<.0001)和主观规范(<.05)是对水果和蔬菜推荐日摄入量的意愿的显著预测因素。在模型 2 中,态度(=.0001)和感知行为控制(<.0001)被证明是意图的显著预测因素。从模型 1(R2=.304)到模型 2(R2=.559),R 方的变化为 0.255(F=40.08,<.0001),第二个模型中增加了感知行为控制。TPB 可能是评估 BEAW 与水果和蔬菜意愿相关因素的合适框架。旨在增加 BEAW 水果和蔬菜摄入量的干预措施应优先考虑修改感知行为控制。
