Role theory: Literature review and implications for patient-pharmacist interactions

The use of role theory informs both researchers and practitioners about the practice of pharmacy and patient interactions. Still, there is much work to be done in role theory and pharmacy research. Experimental designs, longitudinal studies, and qualitative research methodologies may warrant greater use and attention. Role change should be identified as a priority, and research is needed to elucidate what interventions change patients' and pharmacists' expectations of the patient-pharmacist interaction.
