Infant 1 and 2 students showed no statistically significant main or cross-level CREST treatment effects, which the authors attribute to low measurement reliability in ages 4-5¶

Subclaims¶

q3 i? For Infant 1 and 2, intent-to-treat HLM analyses on the total CREST, Attachment, and Engagement scores found no statistically significant main treatment effects or cross-level interaction effects, with less than 1% additional variance explained. → Krystal M. Hinerman 2014 q3 i? The authors interpret the null Infant 1-2 results as likely due to low reliability of paper-and-pencil measurement of latent constructs in participants aged 4-5, while noting positive coefficients. → Krystal M. Hinerman 2014

q3 · i? · causal · r2

Intent-to-treat HLM analyses for the Infant 1 and 2 survey version of the cluster-randomized trial, with treatment as a Level 2 predictor and composite pretest at Level 1, on total CREST, Attachment, and Engagement outcomes. No significant effects; equivalence was not tested.

"No statistically significant main treatment effects or cross-level interaction effects were noted and adding the treatment indicator to the Level 2 models explained less than 1% additional variance in slope and intercept over the model with only the pretest as a predictor."
