“…Several recent studies have evaluated the effects of prompting, education, and reinforcement techniques on such health-related behaviors as exercise (Brownell, Stunkard, & Albaum, 1980), smoking control (Jason, Clay, & Martin, 1979), immunization of preschoolers (Yokley & Glenwick, in press), participation in nutrition programs for the elderly (Bunck & Iwata, 1978), and compliance with preventive dental practices (Iwata & Becksfort, 198 1;Reiss, Piotrowski, & Bailey, 1976). In general, results of these and other studies in the behavioral community psychology literature have suggested that techniques consisting of either impersonal or minimal prompts (e.g., public service announcements, notes) are not as effective as intensified (i.e., repeated, personal, or educational) prompts in improving participation, and that a combination of prompting plus reinforcement is likely to produce the most consistent positive outcomes.…”
