Abstract
Objectives Parental beliefs about child television viewing may affect the way parents regulate child television viewing. Despite this, little research has focused on the development of measures of parental beliefs about child television viewing, particularly among ethnic minority parents and parents of young children. This study's objective was to develop and test a culturally-based measure of parental beliefs about television viewing in low-income Mexican American mothers of preschoolers. Methods Using a cross-sectional study design, 22 items reflecting parental beliefs about influences of TV on children were developed and assessed for psychometric properties in a sample of 312 low-income Mexican American mothers of preschoolers. Results Using exploratory factor analysis, we identified four factors reflecting four domains of parental beliefs: positive general beliefs, positive sleep-related beliefs, positive functional beliefs, and negative general beliefs. Internal reliabilities were acceptable (Cronbach's alpha = 0.70–0.89) for all factors except negative general beliefs (Cronbach's alpha = 0.61). Positive sleep-related beliefs and Positive Functional Beliefs were correlated with children's average daily hours of TV (r = 0.16, p < .01; r = 0.22, p < .001, respectively) and with mother's average daily hours of TV (r = 0.14, p < .05; r = 0.22, p < .001, respectively), providing initial support for construct validity. Conclusions for Practice The Beliefs about Child TV viewing scale measures four domains of parental beliefs regarding child TV viewing, and has good initial reliability and validity for three factors. Future use will allow investigators to conduct more in-depth evaluations on the influence of parental beliefs on the way parents shape their child's use of the TV.
