Employee and organizational factors associated with participation in an incentive-based worksite smoking cessation...

This study investigated employee and worksite characteristics prospectively predictive of participation among 474 smokers in nine different worksites taking part in a year-long incentive-based smoking cessation program. Several different ways of defining participation (e.g., joining versus level of attendance, first 6 months versus entire program) were studied. A consistent pattern of results was observed across two of the participation indices, joining the program and participating in one or more monthly follow-up meetings. Both worksite (number of employees, previous health promotion history, degree of support from management) and employee (gender, motivation, previous quit attempts) variables were predictive of participation. Logistic regression analyses revealed that each set of variables, worksite and employee characteristics, was significantly related to participation after controlling for the effects of the other set. We were less able to predict level of attendance among participants who joined the program. Implications of these findings for future studies of participation in health promotion programs are discussed.
