Absorption: an individual difference to consider in mind-body interventions.

Given that mind-body interventions constitute a major portion of complementary and alternative medicine used by the public, it seems important to explore those human characteristics that may contribute to the efficacy of mind-body interventions in those who are most likely to benefit. One such characteristic, absorption, reflects an individual's cognitive capacity for involvement in sensory and imaginative experiences in ways that alter an individual's perception, memory, and mood with behavioral and biological consequences. Thus, one's level of absorption may potentially create differential treatment effects in mind-body intervention outcomes. Conducting practical clinical trials helps address the challenge of determining whether a specific mind-body modality intervention may be effective. Such trials may be strengthened by including measures of personality dimensions such as absorption.
