ABSTRACT

Objective: The purpose of this study was to examine the definition of intervention fidelity, theoretical background, and components, and examine the trends of intervention fidelity research in occupational therapy through a literature review. Methods: As a literature review study, this research was based on studies related to the intervention fidelity of occupational therapy among those studies published in foreign journals during the past 20 years from January 2000 to December 2020. The target literature was analyzed in terms of the components of intervention fidelity and the tendency of intervention fidelity according to occupational therapy field. Results: As a result of analyzing the studies, there were a total of five studies that included intervention design, training providers, and delivery of intervention, and three studies that included the reception of intervention. Finally, none of the studies included the enactment of intervention skills. As a result of analyzing the tendency of intervention fidelity according to the occupational therapy field, two studies on intervention fidelity of sensory integration intervention, one study on occupational performance coaching, one study on metacognitive rehabilitation intervention, and one study on daily therapy to improve depression and functional outcomes for older adults were found. Conclusion: As a result of examining the trend of intervention fidelity research in the field of occupational therapy, the development of an intervention fidelity evaluation centered on sensory integration interventions and research applying the same were mainly conducted, and research on intervention fidelity in various fields has since continued. Recently, there have been studies by which many components of intervention fidelity have been reflected, which is a result of high interest and importance of intervention fidelity in occupational therapy. In various fields of occupational therapy in Korea, studies on the development of intervention fidelity should increase, and studies on measurement evaluations of intervention fidelity are also expected.
