Client-Centred Occupational Therapy for Persons with Mental Retardation: Implementation of an Intervention Programme in Activities of Daily Living Tasks

Abstract

The aim of this study was to implement a single-case design to evaluate the outcomes of a specified occupational therapy intervention programme. The intervention programme was based on a client-centred top-down approach and followed the Occupational Therapy Intervention Process Model. The interventions included both restorative and adaptive strategies to improve performance of the activities of daily living (ADL) tasks the participants defined as relevant and meaningful. Three women with moderate mental retardation living alone in apartments with support from professionals were included in the study. The Assessment of Motor and Process Skills was used to evaluate for changes in ADL motor and ADL process ability. The Assessment of Awareness of Disability was used to evaluate changes in the client's awareness of disability. The results showed improvements for all participants but patterns of changes were different between the participants and the outcome variables. ADL process ability was the only outcome variable that improved in all participants. The results are discussed in relation to the design used for evaluating intervention efficacy. Future improvements in the process of evaluating occupational therapy interventions are suggested.
