Video feedback intervention shows significant effects on maternal sensitivity in cerebral palsy dyads

A randomized controlled trial evaluated the Video Feedback Intervention to Promote Positive Parenting adapted for Cerebral Palsy (VIPP-CP) in 40 mother-child dyads where the child has cerebral palsy. The intervention was compared to phone calls and face-to-face interviews, though the study setting and follow-up duration were not reported. No primary outcome was specified, and safety data including adverse events and discontinuations were not reported.

The intervention showed significant effects on three specific outcome measures: the 'Supporting the Child' subdimension of the Maternal Sensitivity Scale, and both the 'Sensitivity' and 'Encouragement' dimensions of the Parent-Child Interaction Observation Form. However, the exact numerical results, effect sizes, confidence intervals, p-values, and direction of effects were not reported, limiting quantitative interpretation of the findings.

Key limitations include the small sample size of 40 dyads and the absence of reported effect sizes, confidence intervals, and p-values. The clinical significance of the observed effects on these specific subdimensions remains unclear, and long-term effects were not assessed. The RCT design suggests causal inference is possible for the measured outcomes, but the magnitude of any effect is unknown.

For clinical practice, these findings suggest that video feedback interventions like VIPP-CP may influence specific aspects of maternal sensitivity and parent-child interaction in families affected by cerebral palsy. However, clinicians should recognize the preliminary nature of this evidence given the small sample and incomplete reporting of statistical details. Further research with larger samples and more comprehensive outcome reporting is needed to establish the intervention's clinical utility.
