A simple reinforcement strategy for increasing attendance at a fitness facility.

Abstract

The purpose of the present study was to examine the effect of a previously untested reinforcement strategy (i.e., 1 month's free membership) on attendance at a fitness facility. Participants were paying members of a fitness facility randomly assigned to control ( n = 100), placebo ( n = 100), and reinforcement ( n = 100) conditions. The control condition received no intervention; the placebo condition received a letter by mail; and the reinforcement condition received the same letter by mail, except that it included an additional paragraph instructing them that they could earn 1 month's free membership if they attended the fitness facility at least 12 times in the next month. Attendance was monitored for I month baseline and postintervention by using the facility's computer system. Analysis of variance, t tests, and chi-square analysis all revealed that the reinforcement condition had the best attendance record during the intervention period. These preliminary results shed some light on increasing attendance at a fitness facility. Discussion highlighted the practical implications of the findings and offered directions for future research.
