and Early Childhood Home Program (MIECHV) to do one or more of the following: 1) Further how reflective supervision is measured (e.g., explore additional aspects of the validity not explored in the measure development, adapt the measure for supervisees, validate against observational measures); 2) Use SuPRS-HV to understand how reflective supervision practices may affect outcomes (e.g., for home visitors, for home visitor-family relationships, or for families); 3) Develop tools to help home visiting programs use SuPRS-HV to improve practice (e.g., for monitoring performance or quality improvement); and/or 4) Use SuPRS-HV to describe how reflective supervision practices vary (e.g., by communities, staff characteristics, populations served). Findings from these projects will inform early childhood home visiting policy, practice, or research and help people in the field better understand reflective supervision practices.
