Unlabelled

The equivalency of behavioral interventions has led to the consideration of whether patient-related factors influence clinical trial outcomes. The primary purpose of this secondary analysis was to determine if treatment preference and patient expectation were predictors of trial outcomes and if selected patient-satisfaction items were appropriate as outcome measures. Perceived effectiveness, treatment preference, and patient expectation were assessed before random assignment, and patient satisfaction was assessed 6 months later. Patient preference was associated with perceived effectiveness for those with no treatment preference and those preferring graded exposure. Higher patient expectation was associated with higher perceived effectiveness ratings for all treatments i
