| Abstract: Patient preferences for treatment refer to positive or negative attitudes toward particular treatments. Preferences present potential threats to validity in intervention evaluation research. Evidence suggests they influence enrollment in a study, participation in and adherence to treatments under evaluation, attrition, and outcome achievement. This panel focuses on an explanation of the mechanisms underlying the impact of patient preferences for treatment on validity and a synthesis of empirical evidence supporting their impact, including the results of a methodological study. |
| Preferences for Treatment: Methodological Effects |
| Souraya Sidani, Ryerson University, s.sidani@utoronto.ca |
| The first paper offers a detailed review of the mechanisms through which preferences for treatment influence internal and external validity. Results of various studies, including those of a methodological study conducted by the presented, that examined the impact of preferences on enrollment, attrition, compliance with treatment, and outcome achievement will be synthesized. |
| Correlates of Preferences |
| Joyal Miranda, University of Toronto, joyal.miranda@utoronto.ca |
| This paper identifies socio-demographic and clinical factors that are associated with an explicit expression of a treatment preference. The clinical factors related to the type, severity, and duration of the presenting problem (i.e., insomnia). The treatment options included two theoretically sound behavioral interventions for the management of insomnia. |
| Clinical and Methodological Consequences of Preferences |
| David Streiner, University of Toronto, dstreiner@klaru-baycrest.on.ca |
| The last paper in this panel will end with an open discussion of the clinical and methodological consequences of preferences for treatment. |
