Existing measures of feeding and physical activity parenting strategies have not been validated for use among Hispanic mothers of adolescent and preadolescent daughters with overweight. The purpose of this study was to investigate the factor structure of the Parenting strategies for Eating and Activity Scale (PEAS) among 134 Hispanic mothers (Mage=38.81, SD±6.34) of adolescent and preadolescent daughters with overweight. Results from this exploratory study revealed that a three-factor structure (Limit Setting, Monitoring, and Discipline) and a 13-item revised PEAS measure might be better suited for use with this population. The revised Limit Setting, Monitoring, Discipline, and total subscales had good reliability (α=0.89, α=0.88, α=0.90, and α=0.87, respectively) and the subscale inter-item correlations were strong. To assess the concurrent validity, the revised PEAS subscales were correlated with both subscales of the Behavioral Strategies to Reduce Fat and Increase Fiber (Parent Report) in a subset of the sample (n=78). The Monitoring and Discipline subscales were found to be correlated with the Behavioral Strategies to Reduce Fat (r=.36 and r=.27, p<.05, respectively) and Increase Fiber (r=.40 and r=.35, p<.01, respectively) subscales. However, the revised PEAS Limit Setting subscale was not correlated with either Reduce Fat or Increase Fiber strategy. Taken together, these results indicated some degree of concurrent validity. Results from this study should be cross-validated using confirmatory factor analysis approaches.
现有的喂养和身体活动育儿策略测量方法尚未在超重的青春期和青春期前女儿的西班牙裔母亲中得到验证。本研究的目的是调查134名超重的青春期和青春期前女儿的西班牙裔母亲(平均年龄=38.81,标准差±6.34)中饮食和活动育儿策略量表(PEAS)的因子结构。这项探索性研究的结果表明,三因子结构(限制设定、监督和纪律)以及13项修订后的PEAS测量方法可能更适合该人群使用。修订后的限制设定、监督、纪律和总分量表具有良好的信度(分别为α=0.89、α=0.88、α=0.90和α=0.87),且分量表的项目间相关性很强。为了评估同时效度,在样本的一个子集中(n=78),将修订后的PEAS分量表与减少脂肪和增加纤维行为策略(家长报告)的两个分量表进行了相关性分析。发现监督和纪律分量表与减少脂肪行为策略(分别为r=.36和r=.27,p<.05)以及增加纤维行为策略(分别为r=.40和r=.35,p<.01)分量表相关。然而,修订后的PEAS限制设定分量表与减少脂肪或增加纤维策略均无相关性。综合来看,这些结果表明了一定程度的同时效度。本研究的结果应用验证性因子分析方法进行交叉验证。
