The objective of this study was to develop and validate a brief instrument -- the Perceived Efficacy in Patient-Physician Interactions Questionnaire (PEPPI) -- to measure older patients' self-efficacy in obtaining medical information and attention to their medical concerns from physicians. The study concludes that PEPPI is a valid and reliable measure of older patients' perceived self-efficacy in interacting with physicians. This instrument may be useful in measuring the impact of empowerment interventions to increase older patients' personal sense of effectiveness in obtaining needed health care.
