The number of times attended as a factor in the success of a comprehensive hospital-based approach to health promotion.

This study assesses the relationship between a perceived change in a health-related behavior or attitude and the number of times an individual participates in a weekly hospital-based health promotion program. A survey was distributed to participants in April 1995. A univariate probit evaluation shows that the number of times attended and age have positive effects on the likelihood of change. As the number of times an individual attends increases, the more likely the person is to change, possibly revealing a reinforcement mechanism. It is important to learn the most effective way to raise attendance so the reinforcement process reaches more individuals.
