Study aims, research questions, and hypotheses.

Study aim Research question/hypothesis
1. Quantify the levels of program
  implementation of the ezParent in
  primary care using the RE-AIM
  framework.		 Research question: What is the degree
of Reach, Efficacy, Adoption,
Implementation, and Maintenance of
the ezParent Program in pediatric
primary care?
2. Test the direct effects of the ezParent
  Program on parenting outcomes
  (parenting behavior, self-efficacy, and
  stress) and child outcomes (child
  problem and prosocial behavior)
  compared to the enhanced usual care
  control condition (Health-e Kids)
  among low-income parents with
  young children seen in primary care.		 Hypothesis 1: Relative to parents in the
control condition, parents in the
ezParent condition will report greater
improvements in parenting and child
outcomes at the 3-month assessment.
Hypothesis 2: The improvements in
parenting outcomes and child outcomes
the ezParent condition relative to the
control condition will be maintained
through the 6- and 12-month
assessments.
3. Compare the cost-effectiveness of the
ezParent relative to control for
parenting and child outcomes.		 Hypothesis: The ezParent is
cost-effective relative to the control for
parenting and child outcomes.
