Issues in the measurement of satisfaction with treatment.

Patients satisfaction with treatments is a growing area of research that has tremendous potential to provide outcome measures for clinical trials and disease management programs. It also has applications in marketing and product development, especially for the treatment of chronic diseases. The objective of this review is to demonstrate that treatment satisfaction is a distinct area of research that has produced some important initial results. We define treatment satisfaction and provide a conceptual framework that clarifies the role of treatment expectations, preferences, and satisfaction in the context of healthcare in general. Nineteen articles were selected from more than 1,400 abstracts and were reviewed for the following information: (1) topics covered; (2) method used to design the measure; (3) descriptive statistics; (4) assessment with respect to the attributes in the Instrument Review Criteria of the Medical Outcome Trust's Scientific Advisory Committee; and (5) covariates. We conclude that some important initial results about treatment satisfaction have been obtained, but that much work remains to be performed. We recommend that future research devote more attention to qualitative research with patients, assessment of the measures, and the covariates presented in the conceptual model. We also recommend that decision makers insist on measures that meet these criteria.
