The purpose of this study was to: (1) develop and psychometrically test a survey designed to assess Cooking Matters for Adults (CMA); and (2) assess changes in outcomes from pre- to post-pilot testing in English-speaking CMA classes to support the construct validity of the survey.
Cognitive interviewing participants were drawn from a low-income convenience sample in Omaha, Nebraska (N = 21). The survey included items to assess dietary patterns and choices, sociodemographics, and psychosocial correlates. Analyses were conducted with SPSS and included descriptive statistics, exploratory factor analysis, Cronbach's alpha, and paired sample t-tests.
Cognitive interviewing resulted in changes to survey layout and wording. Factor analysis revealed 4 actors with Cronbach alphas supporting internal consistency. Between pretest and posttest, fruit intake increased (p < .05) and non-fried potatoes decreased (p < .05). Selection of healthy dietary options (low-fat dairy and milk, sodium, lean meats; p's < .05), healthy food preparation (p < .001), and cooking confidence (p < .001) increased and perceived barriers to cooking (p < .01) decreased.
The CMA Survey includes psychometrically sound items and positive self-reported changes. This survey can be a valuable resource for other similar programs.
本研究的目的是:(1)开发并对一项旨在评估成人烹饪事项(CMA)的调查问卷进行心理测量学测试;(2)评估在说英语的CMA课程中从试点测试前到试点测试后的结果变化,以支持该调查问卷的结构效度。
认知访谈参与者来自内布拉斯加州奥马哈市的一个低收入便利样本(N = 21)。该调查问卷包括评估饮食模式和选择、社会人口统计学以及心理社会相关因素的项目。使用SPSS进行分析,包括描述性统计、探索性因素分析、克朗巴哈系数和配对样本t检验。
认知访谈导致了调查问卷布局和措辞的改变。因素分析揭示了4个因素,克朗巴哈系数支持内部一致性。在预测试和后测试之间,水果摄入量增加(p <.05),非油炸土豆摄入量减少(p <.05)。健康饮食选择(低脂乳制品和牛奶、钠、瘦肉;p值<.05)、健康食物制备(p <.001)和烹饪信心(p <.001)增加,烹饪的感知障碍减少(p <.01)。
CMA调查问卷包括心理测量学上合理的项目和积极的自我报告变化。该调查问卷对于其他类似项目可能是一个有价值的资源。
