Testing the Effects of the Caregiver Interaction Profile Training on the Interactive Skills of Daycare Providers

The goal of this clinical trial is to test the Caregiver Interaction Profile (CIP) training program (Helmerhorst et al., 2017) promoting the relational quality between professional caregivers and children in daycare. The main questions it aims to answer are:

• Does the CIP training program, compared to no training, improve the relational quality between daycare providers and children in daycare?

• Does the CIP training program, compared to no training, foster children's social, emotional, and language development? Daycare providers assigned to the "training group" will participate in the CIP training program, which uses video-recorded interactions between the daycare providers and children in daycare to give feedback on the relational quality as observed in the videos. Daycare providers assigned to the "waiting list control group" will initially not take part in the training program but will receive the training after the study is finished. All daycare providers' daily interactions with the children in daycare will be filmed before and after the training in order to see if there has been a change in relational quality for the daycare providers in the training group (compared to the control group). Daycare providers in the training and control groups will also fill out questionnaires about the social, emotional, and language development of the children in their care.

Researchers will compare daycare providers (and the children in their care) in the "training group" to daycare providers (and the children in their care) in the "control group" to see if the relational quality in the training group improves more than that in the control group as a result of the CIP training, and how that impacts the social, emotional, and language development of children.
