Assigned versus participative goal setting and response generalization: Managing injury control among professional pizza deliverers.

Abstract

Safety belt use, turn signal use, and intersection stopping were observed at 3 pizza delivery locations per driver's license plate numbers. After baseline observations, employees at 1 store participated in goal setting targeting complete stops. Employees at the other store were assigned a goal. Over 4 weeks, the group's percentages of complete intersection stopping were posted. Both intervention groups significantly increased their complete intersection stops during the intervention phase. The participative goal-setting group also showed significant increases in turn signal and safety belt use (nontargeted behaviors) concurrent with their increases in intersection stopping (targeted behaviors). Drivers decreased their turn signal and safety belt use concurrent with the assigned goal condition targeting complete stops.
