Challenges and innovations in enhancing adherence

Adherence is a complex phenomenon involving interactions among the individual, the environment and the community. In an adherence workshop, a small group of investigators discussed their experiences with challenges and innovations regarding adherence gleaned from clinical research. This article summarizes the information and outcomes of that meeting. Guided by theoretical frameworks for understanding and promoting adherence, challenges in the areas of measurement, community-based research, and interventions were explored and innovations for meeting these challenges suggested. The article concludes with recommendations for enhancing the adherence agenda: (1) adherence research must have a well-defined conceptual and theoretical basis; (2) individual perceptions and social context of behavior must be incorporated; (3) research must be undertaken as a collaborative process involving participants and the community. Looking ahead, it is clear that if we hope to develop a new and integrated model of adherence, we must continue to advance theory through theory testing, with particular attention given to mediators and diverse samples. Moreover, an interdisciplinary agenda is necessary to set the stage for bringing together researchers from various disciplines and backgrounds with both participants and community representatives.
