ABSTRACT

Background:

Universal, high quality childcare offers a unique opportunity to prevent developmental trajectories leading to mental health problems. Yet, growing evidence has shown that the process quality of Norwegian childcare centers varies greatly, and there is lack of research-based models for quality building.

Objective:

To examine whether a model for quality building in childcare centers, Thrive by Three, increases the quality of child-caregiver interactions, and promote child development, well-being and mental health.

Methods:

The Thrive by Three study is a clustered randomized controlled trial involving 187 toddler-groups in childcare centers across seven municipalities within southern and central Norway. Each center is randomly allocated to the intervention or waitlist (control) group. Data is collected at four points: pre-intervention (T1), mid-way (T2), post-intervention (T3), 1-year post-intervention (T4). Primary outcomes are changes in child-care quality measured by the Classroom Assessment Scoring System (CLASS) toddler version, Student-Teacher Relationship Scale short form (STRS-SF), and Life in Early Childhood Programs (LECP), as well as child development and mental health, measured by the The Brief Infant Toddler Social and Emotional Assessment (BITSEA, parent and teacher report), the Caregiver -Teacher Report Form (C-TRF) and Child Behavior Checklist (CBCL, parent report) from the Achenbach ASEBA from 1,5-5 years, and child well-being measured by the Leiden Inventory for Child’s Well-Being in Day Care (LICW-D). Secondary Child cortisol levels are assessed in a subsample of 372 children.

Results:

As of November 2018 a total of 1531 children and 769 staff, from 187 toddler-groups were recruited. The recruitment of staff will be ongoing until May 2020, due to turnover. As of January 2020, the intervention group has been working with Thrive by Three for 1.5 year. Data at T1, T2 and T3 from both the intervention and control group has been completed and T4 will be completed in June 2020

Conclusions:

The present study makes an important contribution to the field of quality-building in childcare centers. The results will provide greater insight into how high quality can be obtained and the effects of high-quality early childcare on child mental health. This in turn will be significant for policymakers and to the Norwegian society at large. Clinical Trial: Clinical Trials NCT03879733, Registered on March 25, 2019.
