To develop and test a comprehensive, culturally based measure of parenting practices regarding television (TV) viewing in low-income Mexican-American mothers of preschoolers.
Low-income Mexican-American female primary caregivers of preschoolers were recruited in urban safety-net pediatric clinics during the 2013 to 2014 academic year. Items on parenting practices regarding TV viewing were developed from a prior scale, review of the literature, and results from semistructured interviews. Items were administered by phone, and analyses included evaluation of the factor structure and psychometric properties of a 40-item measure of parenting practices regarding TV viewing (PPRTV).
Using exploratory factor analysis, a 7-factor model emerged as the best fit for the data representing the following domains of parenting practices: time restriction, behavioral control, instructive practices, coviewing, planful restriction, reactive content restriction, and commercial endorsement. Internal reliabilities were acceptable (Cronbach's alpha >.75). Correlations among the resulting subscales were small to moderate (rs = 0.01-0.43). Subscales were correlated with child TV viewing amounts: time restriction (-0.14, p < .05); behavioral control (0.27, p < .001); coviewing (0.16, p < .01); planful restriction (-0.20, p < .001); and commercial endorsement (0.11, p < .05), which provides support for construct validity.
The PPRTV scale measures 7 domains of parenting practices and has good initial reliability and validity. It allows investigators to conduct more in-depth evaluations of the role parents play in socializing young children on TV use. Results of such work will be important to informing the design of interventions aiming to ensure healthy screen media habits in young children.
开发并测试一种全面的、基于文化的育儿实践量表,用于评估低收入墨西哥裔美国学龄前儿童母亲在电视观看方面的育儿行为。
在2013至2014学年期间,从城市安全网儿科诊所招募低收入墨西哥裔美国学龄前儿童的女性主要照顾者。关于电视观看育儿实践的条目是根据先前的量表、文献综述以及半结构化访谈的结果制定的。通过电话进行条目施测,分析包括对电视观看育儿实践40项量表(PPRTV)的因子结构和心理测量特性的评估。
通过探索性因子分析,出现了一个7因子模型,最能拟合代表以下育儿实践领域的数据:时间限制、行为控制、指导性实践、共同观看、有计划的限制、反应性内容限制和商业认可。内部信度可以接受(克朗巴赫α系数>.75)。所得子量表之间的相关性为小到中等(rs = 0.01 - 0.43)。子量表与儿童电视观看量相关:时间限制(-0.14,p <.05);行为控制(0.27,p <.001);共同观看(0.16,p <.01);有计划的限制(-0.20,p <.001);以及商业认可(0.11,p <.05),这为结构效度提供了支持。
PPRTV量表测量了7个育儿实践领域,具有良好的初始信度和效度。它使研究人员能够更深入地评估父母在使幼儿养成健康电视使用习惯方面所起的作用。此类研究结果对于为旨在确保幼儿养成健康屏幕媒体习惯的干预措施设计提供信息至关重要。
