缺乏可靠的，有效的和理论上一致的措施来评估父母的自我效能，帮助儿童预防肥胖的行为。为四种行为制定父母自我效能的测量方法：1）帮助他们的孩子每天至少进行60分钟的中等强度的体力活动，2）帮助孩子每天食用五份水果和蔬菜，3）每周限制含糖饮料一次，4）每天限制果汁的消费量为6盎司。规模发展的顺序方法。根据理论和定性访谈产生了一个项目库，并由内容专家进行了审查。对4-10岁儿童的父母或法律的监护人进行量表管理。使用主成分分析减少项目库。在一个单独的样本中，验证性因素分析测试所产生的模型。304名父母，大多数是妇女（88%），低收入（61%）和单亲（61%）。种族分布为40%黑人和37%白色。所有量表均具有极好的拟合指数：比较拟合指数> .98，卡方（Pediatrics 120 Suppl 4：S229-253，2007）= .85 - 7.82。α和一周重测ICC ≥ 0.80。自我效能量表得分与其相应行为之间的显著相关性范围为0.13 - 0.29（均p <0.03）。我们开发了四个，四个项目的自我效能感量表具有良好的心理测量特性和结构效度，使用不同的样本的父母。临床试验注册：NCT 01768533。
Reliable, valid and theoretically consistent measures that assess a parent’s self-efficacy for helping a child with obesity prevention behaviors are lacking. To develop measures of parental self-efficacy for four behaviors: 1) helping their child get at least 60 minutes of moderate intensity physical activity every day, 2) helping one’s child consume five servings of fruits and vegetables each day, 3) limiting sugary drinks to once a week, and 4) limiting consumption of fruit juice to 6 ounces every day. Sequential methods of scale development were used. An item pool was generated based on theory and qualitative interviews, and reviewed by content experts. Scales were administered to parents or legal guardians of children 4–10 years old. The item pool was reduced using principal component analysis. Confirmatory factor analysis tested the resulting models in a separate sample. 304 parents, majority were women (88%), low-income (61%) and single parents (61%). Ethnic distribution was 40% Black and 37% white. All scales had excellent fit indices: Comparative fit index > .98 and chi-squares (Pediatrics 120 Suppl 4:S229-253, 2007) = .85 – 7.82. Alphas and one-week test-retest ICC’s were ≥ .80. Significant correlations between self-efficacy scale scores and their corresponding behaviors ranged from .13-.29 (all p < .03). We developed four, four-item self-efficacy scales with excellent psychometric properties and construct validity using diverse samples of parents. Clinical trial registration: NCT01768533.
