 The effectiveness of JP has been evaluated in a number of studies, all in a group setting. JP has beneficial short-term effects on pain and function in patients with established RA and moderate functional problems. Using assistive devices reduces pain during task performance in comparison to normal methods and altering working methods significantly reduces difficulties in activities of daily living ADL. However this generally does not result in significant behavioral changes and a long-term impact on reducing pain and maintaining function may only be reached if JP is taught using behavioral education methods. Additionally, adherence of RA patients to different interventions is generally modest, which may well determine the effectiveness of any given intervention, especially in the long-term.
