Evaluating Effectiveness of Group Intervention Working on Executive Function for Children with Attention Deficit Hyperactivity Disorder: A Prospective Observational Cohort Study

Abstract

Introduction: The objective of this study is to evaluate the effectiveness of Simon says program (SSP), a strategy-based group intervention program working on executive function (EF) for children with attention deficit hyperactivity disorder (ADHD). Methods: A prospective observational cohort study was conducted from December 2021 to July 2022 recruiting 21 SSP participants, either they were on stimulant or not on stimulants, and 12 other ADHD patients who are on stimulant medication only without prior participation in SSP, using convenience sampling method, from Child Development Clinic Hospital Sultan Ismail. NICHQ Vanderbilt Assessment Follow Up Scales (VAS) were used to measure its effectiveness and the significance of score differences before and after SSP were assessed using paired sample t-test of Statistical Package for Social Science (SPSS) version 28.0 software. Results: Total of 33 children participated in the study. From our study, only those participants on behavioural therapy alone showed statistically significant reduction in inattentive score, hyperactivity score and total symptoms score at the third month and sixth month after joining SSP from parents-rated VAS. There were no statistically significant differences in the average VAS performance score for both groups. Conclusion: SSP could be an effective behavioral intervention for children with ADHD children. Limitations included lacking clear generalizability due to the convenience sampling method and potential inter-rater variability.
