Patient adherence to therapy is one of the key determinants of treatment success, while low levels of adherence potentially lead to the worsening of health outcomes and to increased health care costs. The automatic identification of psychobehavioral targets, i.e., patterns in patients’ psychological characteristics and behaviors that positively or negatively affect their adherence level, should help physicians develop therapies that influence adherence and improve health outcomes. These targets can also be used to develop psychobehavioral interventions, i.e., plans of actions to modify patients’ behavior and psychological stance, that maintain or improve adherence level by motivating patients to avoid negative psychobehavioral targets or to achieve positive ones. In this work, we propose a theoretical decision support framework that helps patients better adhere to therapy by automatically identifying psychobehavioral targets and selecting corresponding psychobehavioral interventions. We use datadriven techniques to discover these targets from patient data. Specifically, we apply dominance-based rough set theory to induce decision rules from data and then automatically extract targets from these rules. Once these targets are identified, we apply expert knowledge to select the most appropriate generic psychobehavioral interventions and customize them to patient characteristics. We illustrate the proposed framework using a case study of patients with atrial fibrillation who follow oral anticoagulation therapy. We describe the psychobehavioral targets identified from data and present associated psychobehavioral interventions.
