Video feedback promotes relations between infants and vulnerable first-time mothers: a quasi-experimental study

BACKGROUND: Supporting early mother-infant relationships to ensure infants’ future health has been recommended. The aim of this study was to investigate whether video feedback using the Marte Meo method promotes a healthy early relationship between infants and vulnerable first-time mothers. Video feedback or usual care was delivered by health visitors during home visits in Danish municipalities. METHODS: This quasi-experimental study included pre- and post-tests of 278 vulnerable families. Mothers were allocated to an intervention group (n = 69), a comparison group (n = 209) and an exactly matched video subsample from the comparison group (n = 63). Data consisted of self-reported questionnaires and video recordings of mother-infant interactions. Outcomes were mother-infant dyadic synchrony (CARE-Index), maternal confidence (KPCS), parental stress (PSS), maternal mood (EPDS) and infant socialemotional behaviours (ASQ:SE). The data were analysed using descriptive and linear multiple regression analysis. RESULTS: The levels of dyadic synchrony in the intervention group had significantly improved (p < 0.001) at follow-up with a mean score of 9.51 (95%CI;8.93–10.09) compared with 7.62 (95%CI;7.03–8.21). The intervention group also showed a higher level of maternal sensitivity with a mean score of 9.55 (95%CI;8.96–10.14) compared with 7.83 (95%CI;7.19–8.46) in the matched video subsample (p < 0.001). With respect to infant cooperation, similar improvements were found with a mean score of 9.43 (95% CI;8.88–9.99) in the intervention group compared with 7.73 (95%CI;7.13–8.33) in the matched video subsample from the comparison group (p < 0.001). Furthermore, mothers in the intervention group reported significantly lower levels of parental stress with a mean score of 32.04 (95%CI;30.13–33.94) compared with 35.29 (95%CI;34.07–36.52) in the comparison group (p = 0.03), as well as higher levels of maternal confidence with a mean score of 41.10 (95%CI;40.22–41.98) compared with 40.10 (95%CI;39.65–40.56) in the comparison group (p = 0.04). No significant differences were found in EPDS and ASQ:SE. CONCLUSION: The findings support the assumption that video feedback using the Marte Meo method early after birth may strengthen the relationship between infants and vulnerable firsttime mothers as well as improve maternal psychosocial functioning. Further research applying random assignment is needed to strengthen these conclusions; further research is also needed to assess any long term effects of the video feedback intervention using the Marte Meo method.
