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.
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。
