q2 i? Neither fidelity/adherence nor dosage showed statistically significant associations with academic outcomes, contrary to the wider implementation literature. → Alexandra Barlow 2015

q2 · i? · causal · r2

Observational implementation analysis from the trial's IPE using four-level hierarchical linear models. The report suggests fidelity's influence may lessen once delivery quality is accounted for, and that classes averaged 20 lessons behind schedule.

"Implementation fidelity and dosage of PATHS appear to be unrelated to academic outcomes. Given the extensive literature base supporting these two aspects of implementation as moderators of intervention outcomes, this was somewhat surprising."
