The effects of consumer dissatisfaction with doctors and medical care services on intentions to seek care and subsequent behavior were estimated using data from four general population studies. Satisfaction was linked to reported intentions regarding care-seeking behavior (choices between self-care and seeking care from a regular doctor or emergency room) in response to both minor and serious medical problems. These results were replicated in two populations with diverse sociodemographic characteristics. Satisfaction scales also predicted subsequent changes in medical care providers and disenrollments from prepaid health plans independent field tests. These results suggest that the behavioral consequences of individual differences in satisfaction with doctors and health care services are noteworthy from both clinical and social perspectives.
