When do cancer patients regret their treatment decision? A path analysis of the influence of clinicians' communication styles and the match of decision-making styles on decision regret

Objective: To test the influence of physician empathy (PE), shared decision making (SDM), and the match between patients' preferred and perceived decision-making styles on patients' decision regret. Methods: Patients with breast or colon cancer (n = 71) completed questionnaires immediately following (T1) and three months after a consultation (T2). Path analysis was used to examine the relationships among patient demographics, patient reports of PE, SDM, the match between preferred and perceived decision-making styles, and patient decision regret at T2. Results: After controlling for clinician clusters, higher PE was directly associated with more SDM (beta = 0.43, p < 0.01) and lower decision regret (beta = 0.28, p < 0.01). The match between patients' preferred and perceived roles was negatively associated with decision regret (beta = -0.33, p < 0.01). Patients who participated less than desired reported more decision regret at T2. There was no significant association between SDM and decision regret (beta = 0.03, p = 0.74). Conclusion: PE and the match between patients' preferred and perceived roles in medical decision making are essential for patient-centered cancer consultations and treatment decisions. Practice implications: Ways to enhance PE and matching the consultation style to patients' expectations should be encouraged. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
