Optimizing an Evidence-Based, Disseminable, Free Internet-Based Parenting Program

The study is a longitudinal factorial optimization trial in a community sample of 800 parents with 1.5- to 3-year-old children. There are 4 experimental factors; each corresponds to the presence vs. absence of an engagement-focused intervention element. This experiment enables the estimation of the individual and combined effects of each element. The specific aims follow. Aim 1: Optimize the effects of EFP on parenting skills by determining which combination of the four experimental engagement-focused intervention elements results in the greatest success of EFP, as reflected in increasing parent warmth and reducing corporal punishment, overreactive and lax discipline. Aim 2: Determine the extent to which boosted meaningful parent engagement in EFP is the mechanism driving the effects of the four engagement-focused intervention elements on parenting skills, and which aspect(s) of engagement (e.g., content consumption; behavioral skills practice) are the key mediators that translate the effects of the four engagement-focused intervention elements into improved parenting. Aim 3: Examine parent (e.g., change readiness; race) and child characteristics (e.g., externalizing behavior; sex) to determine if the optimal intervention package differs among subgroups. Cracking the code of providing parents with an intervention that they actually use, and that improves parenting, could have far-reaching effects (e.g., improving population-level child outcomes).
