具有健康饮食身份的人报告更健康的饮食，并对营养干预表现出更大的接受性，但其他类型的饮食身份可能也很重要。我们开发了饮食身份类型清单（EITI），以评估与四种饮食身份类型的亲和力：健康，肉类，挑剔和情绪化。本研究采用验证性因素分析（CFA）对EITI的因素效度进行了评估，并建立了EITI的信度和聚合效度。在一项电话调查中，968名主要家庭食品购物者完成了EITI和饮食问卷调查; 101人在大约1个月后重复了EITI。CFA显示，11项模型提供了可接受的拟合度（chi（2）= 206; df = 38），CFI = .938，NNFI = .925，RMSEA = .070; SRMR = .059）。EITI表现出可接受的内部信度，Cronbach α的范围从0.61到0.82，对于健康、情绪化和挑剔的类型具有良好的重测信度（Pearson相关系数范围从0.78到0.84）。普通最小二乘法（OLS）用于评估饮食身份类型和饮食分析之间的关系，证明了健康饮食身份和健康饮食摄入量之间的显着假设关系，肉类和挑食的身份和不健康的饮食摄入量。EITI可以促进行为和认知研究，为更有效地设计信息、干预措施和政策以促进健康饮食行为提供重要见解。(c)2013爱思唯尔有限公司保留所有权利。
People with healthy eating identities report healthier diets and demonstrate greater receptivity to nutrition interventions, but other types of eating identity are likely important. We developed the Eating Identity Type Inventory (EITI) to assess affinity with four eating identity types; healthy, meat, picky, and emotional. This study assessed factorial validity, using confirmatory factor analysis (CFA) and established reliability and convergent validity of the EITI. In a telephone survey, 968 primary household food shoppers completed the EITI and a dietary questionnaire; 101 repeated the EITI approximately 1 month later. CFA revealed that an 11-item model provided acceptable fit (chi(2) = 206; df = 38), CFI = .938, NNFI = .925, RMSEA = .070; SRMR = .059). The EITI demonstrated acceptable internal consistencies with Cronbach alpha's ranging from .61 to .82 and good test-retest reliability for healthy, emotional, and picky types (Pearson's correlations ranging from .78 to .84). Ordinary Least Squares (OLS) used to assess relationships between eating identity type and diet analyses demonstrated significant hypothesized relationships between healthy eating identity and healthier dietary intake and meat and picky eating identities and less healthy dietary intake. The EITI could facilitate behavioral and cognitive research to yield important insights for ways to more effectively design messages, interventions, and policies to promote healthy dietary behaviors.
