Basic Elements for Conducting Evidence-Based Occupational Therapy

Abstract

This chapter reports on methodology for evaluating the effectiveness of the interventions discussed in this handbook. The content and the four steps that compose evidence-based interventions are described as well as the various methods for conducting quality assurance. Assessment instruments represent the prerequisites for conducting evaluations of intervention effectiveness. Therefore, their possible aims, psychometric functions, and the process of collecting data and interpreting the results are reported in broad terms. An overview of the various available methods, such as the Goal Attainment Scale for evaluating a single client's progress when participating in therapeutic sessions, is presented. The terminology of outcome statements is discussed. Finally, recommendations for future advances in occupational therapy are suggested.
