Plain English Summary
Background and study aims
We are carrying out a study of 200 families with interaction problems with their infants under the age of 2 years in Norway. Video feedback of Infant-Parent Interaction (VIPI) is a method which is widely practiced in primary healthcare in the Scandinavian countries, but no clinical study has been conducted of its effects on parent-child interaction. In this study, we want to compare the effects of VIPI with usual care on parent-child interaction.
Who can participate?
Families who are considered to have interaction problems with their infants who are less than 2 years of age.
What does the study involve?
The families are randomly allocated to one of two groups: VIPI or treatment-as-usual (TAU). Over a period of 2 years three trained research assistants will visit the families in their homes. During the visit, parents will complete questionnaires and will be videotaped when interacting with their infants for 30 minutes in a natural everyday situation like feeding, playing or nappy changing. These videotapes will later be assessed. We will assess the families before VIPI (T1), after VIPI (T2) and 6 months later. The TAU group in this study receives consultations from health nurses, social and child welfare workers, community psychologists, and practitioners.
What are the possible benefits and risks of participating?
For most parents there will expectedly be an immediate direct treatment benefit either from VIPI or TAU. There will be no risk to the participants.
Where is the study run from?
The VIPI study aims to recruit about 200 families from two major cities and six rural areas in Norway.
When is the study starting and how long is it expected to run for?
The study started in January 2011 and will last until December 2015.
Who is funding the study?
National Network of Infant Mental Health, Oslo (Norway).

A longitudinal randomized controlled trial of the intervention Video-feedback of Infant-Parent Interaction (VIPI) for infants under 2 years of age
It is hypothesized that parents with moderate interaction problems with their infants will profit from the intervention (VIPI) compared to treatment as usual (TAU). Parents with either minor interaction problems or more serious problems will not benefit from VIPI than TAU.
It is hypothesized that maternal depressive symptoms will moderate the effect of VIPI, with more symptoms resulting in less effect.
