Purpose of the article: To review the use of outcome measures, across the domains of activity, participation, and environment, within multidisciplinary early childhood intervention services.

Materials and methods: A systematic literature search was undertaken that included four electronic databases: Medline, CINAHL, EMBASE, and the Cochrane Library and Cochrane Database of Systematic Review. Inclusion criteria were age 0–24 months, having or at risk of a developmental disability, in receipt of multidisciplinary early childhood intervention services, and included outcome measures across all domains of the International Classification of Functioning-Child & Youth (ICF-CY). Only peer-reviewed journal articles were considered. Eligible studies were coded using the Oxford Levels of Evidence. Methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) Scale for randomised controlled trials and the QualSyst for non-randomised control trials.

Results: Of the total of 5764 records identified, 10 were considered to meet inclusion criteria.

Conclusion: Fourteen outcome measures were identified, addressing the domains of activity, participation, and environment. Of these, eight have been recommended in the early intervention literature. While the methodological quality of the 10 studies varied, these papers make a contribution to the body of research that acknowledges the role of routine and enriched environments.
