Barriers to clinical trial recruitment can delay study completion, potentially resulting in increased costs and an unrepresentative sample. In the current study of 150 participants with chronic pain, we used a computerized adaptive choice-based conjoint (ACBC) survey that included 8 characteristics that may affect enrollment in pharmacologic pain treatment trials (i.e., treatment allocation; frequency of pain ratings; treatment administration method; current medications; number of study visits; availability of evening and weekend visits; invasiveness of laboratory procedures; payment).
