Examining Behavioral Interventions for Infancy and Early Toddlerhood: A Systematic Review of Intervention Effects, Parameters, and Participants.

In 30 seconds

This systematic review examined behavioral interventions based on operant learning for children in the first two years of life, focusing on key developmental areas. It synthesized 69 studies with unique participant cohorts, including 1,735 children. Many studies addressed infants in their first year, and a large proportion investigated approaches to increase communication. The review considered intervention effects, procedures, participant characteristics, and circumstances of use, and discussed implications and limitations for practice and future research. The abstract does not report a pooled effect estimate or a single quantitative outcome demonstrating developmental benefit.

Key findings

• The review synthesized 69 studies with unique participant cohorts, including 1,735 children.
• Many studies focused on the first year of life, with a large proportion examining approaches to increase communication.

Why it matters

The review maps a growing body of work on behavioral intervention during infancy and early toddlerhood, a period when children may be identified for support before significant developmental delays emerge. Its synthesis can help clinicians understand which developmental areas and intervention approaches have been studied, while highlighting that the abstract does not establish a single overall effect on developmental outcomes.

What to keep in mind

The abstract provides no pooled effect estimate or specific outcome results, limiting conclusions about the overall effectiveness of these interventions.
