Patient desire for information and decision making in health care decisions

Abstract

OBJECTIVES: To compare results on the Autonomy Preference Index (API) and the Health Opinion Survey (HOS), two instruments that measure patient desire for information and involvement in decision making. DESIGN: Cross-sectional survey. SETTING: University-based primary care outpatient longitudinal and acute care clinic. PATIENTS: 167 patients with benign prostatic hyperplasia, back pain, or mild hypertension seen from October 1991 to December 1992. MEASUREMENTS AND MAIN RESULTS: On the API and the HOS (both scaled from 0 to 1), the patients had intermediate desire for involvement in decision making (median API: 0.42; HOS: 0.36) and higher desire for information (median API: 0.97; HOS: 0.57). With either instrument, the desire for information exceeded that for involvement in decision making (pCONCLUSIONS: Most patients have a high desire for information, the desire for information and involvement in decision making varies substantially among patients, and the API is preferable to the HOS for researchers interested in focusing solely on patient desire for information.
