title: Parenting and Preschooler TV Viewing in Low-Income Mexican Americans: Development of the Parenting Practices Regarding TV Viewing (PPRTV) Scale.
abstract: 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.
