This new Cochrane Review (published November 2019) assessed the effects of video feedback on parental sensitivity and attachment security in children aged under five years who are at risk for poor attachment outcomes.
It includes 22 randomised controlled trials comparing video feedback to no treatment, inactive alternative intervention, or treatment as usual in 1889 parent-child dyads or family units; most included parents were mothers.
The review authors found that, compared to control or no intervention, video feedback may improve parental sensitivity at post-intervention and short-term follow-up (moderate-certainty evidence); however, there is no evidence that it has an effect on child behaviour and the effect on attachment security is mixed (both very low-certainty evidence). Also, there is no evidence that video feedback improves parental stress or anxiety compared to control or no intervention (low-certainty evidence).
