LowQuasi-experimental designNot ApplicableNot established on race; not established on SES; not established on outcome measures assessable at baseline.NoYes. The providers delivering the intervention had master's degrees, whereas the providers delivering the control condition had bachelor's degrees. Having a master's degree is not a requirement for intervention providers. Therefore, it is impossible to separate effects of the intervention from effects of the employing agency or education level of the providers.

This study examines a subsample of a randomized controlled trial. The authors do not describe the subsampling process, so this review assumes it is not random and treats the study as a quasi-experimental design.

Study Registration Identifier: NCT00339365. Study registration was assessed by HomVEE beginning with the 2014 review.
