This manuscript describes two studies: a randomized controlled trial (RCT) and a non-experimental comparison group design (NED). This review addresses the findings of the NED. The review of the RCT is addressed under Raby et al. (2021; Study 1).
This study received a rating of low because of a confounding factor in the design. All members of the intervention group were referred for risk of child maltreatment and had involvement with Child Protective Services (CPS), whereas the comparison group did not have any history of CPS involvement. Therefore, HomVEE is not able to separate the impact of the intervention from the effects of the referral to and involvement with CPS for risk of child maltreatment. Because the study received a low rating for this reason, HomVEE did not assess additional factors that could have influenced the rating, such as whether the study met the baseline equivalence requirement or used valid and reliable measures.
