Characteristics of controlled studies of patient education and counseling for preventive health behaviors

Abstract

To determine characteristics of controlled studies (quasi-experimental and randomized) of clinical patient education/counseling for behavior change to prevent disease, we conducted an extensive literature review of published and unpublished studies from 1971 to 1989. Sixty-four studies with 101 intervention groups met specific criteria for relevance and scientific acceptability. We examine these studies in terms of prevention area, subject source, intervention characteristics, and use of educational principles. Findings reveal many controlled clinical studies in smoking cessation, nutrition, and weight control but sparcity in other areas (injury prevention, exercise, stress, drug and alcohol misuse, STD prevention); an emphasis on communication by a single clinical practitioner; and varied use of educational principles. We recommend adhering to educational principles to enhance likelihood of success.
