Developmental Screening - Evaluation of an m-Health Version of the Parents Evaluation Developmental Status Tools

© Copyright 2016, Mary Ann Liebert, Inc. 2016.Background: Developmental delays are more prevalent in low-income countries and access to developmental screening is severely limited. Introduction: This study evaluated an m-Health version of a standard developmental screening tool, Parents Evaluation Developmental Status (PEDS) and PEDS:Developmental Milestones (PEDS:DM) for use by community health workers (CHWs) in terms of (1) correspondence with conventional paper-based testing by a speech language pathologist (SLP) and (2) inter-rater reliability compared to an SLP. Method: CHWs were trained in a primary healthcare (PHC) setting to administer the newly developed smartphone application version of the PEDS tools. One SLP and two CHWs recruited 207 caregivers who were attending a baby wellness clinic. Caregivers were tested by one CHW using the smartphone application of the PEDS tools; a qualified SLP simultaneously recorded and scored the PEDS tools on the same participants. Results: High positive (100%) and negative correspondence (96%) was found between the paper-based PEDS tools and the smartphone application PEDS tools and between the SLP and CHW. Almost perfect (Cohen's Kappa) inter-rater agreement between conditions was demonstrated (κ = 0.873 to κ = 0.961). Conclusion: Outcomes of the smartphone application, operated by a CHW, corresponded closely to the gold standard PEDS tools operated by a health professional. Trained CHWs can conduct accurate developmental screening using the smartphone version of the PEDS tools.
