Notes from the review of this manuscript
The manuscript reports findings separately for a subset of the intervention group that was randomly assigned to receive video feedback and brochures to enhance sensitive parenting (referred to in the manuscript as the “VIPP group”) and another subset of the intervention group that in addition to the video feedback and brochures was randomly assigned to participate in discussions about the mother’s childhood attachment experiences in relation to their current parenting style (referred to in the manuscript as the “VIPP-R group”). The developers indicated the VIPP and VIPP-R groups received the same intervention. Therefore, this review focused on the findings for the intervention group that received the VIPP home visiting model (which combines the VIPP and VIPP-R subsets). Findings for all outcomes rated high except for the findings for the Child Behavior Checklist (CBCL) Somatic problems. Findings for CBCL Somatic problems did not meet HomVEE’s requirements for measure reliability and rated low.

This study included participants from the following locations:
- State not reported or international
Study participants included first-time mothers with 4-month-old children; these participants were identified through administrative records in one city and five villages in the Netherlands. The study recruited women with low educational levels, defined as more than eight but fewer than 14 years of schooling. Using the Adult Attachment Interview to screen mothers, the study team selected mothers classified as having an insecure attachment style for the study. The study randomly assigned mothers to one of three groups: the Video-feedback Intervention to promote Positive Parenting (VIPP) intervention group (28 mothers), the VIPP-R (VIPP with a representational focus) intervention group (26 mothers), or the business-as-usual comparison group (27 mothers). The full intervention sample included both VIPP and VIPP-R. The analytic sample included 52 participants in the intervention group and 26 participants in the comparison group. Study follow-up took place when children were 40 months old (that is, 36 months after enrollment). At enrollment, the mean age of mothers was 27.8.
The study took place in West Netherlands.
Note: Navigate to the model page for more information about the home visiting model. See the source manuscript for more information about how the model was implemented in this study.
Families assigned to the comparison condition were not eligible to receive intervention services through VIPP. The sole purpose of home visits during the study was for data collection purposes.
There were no subgroups reported in this manuscript.
The study was supported by a Pioneer Award of the Netherlands Organization for Scientific Research NWO (Grant PGS 59-256).
