The Additive Impact of Group and Individual Publicly Displayed Feedback: Examining Individual Response Patterns and Response Generalization in a Safe-Driving Occupational Intervention

Abstract

Additive effects of publicly posting individual feedback following group goalsetting and feedback were evaluated. The turn-signal use of pizza deliverers was studied in a multiple baseline design across two pizza stores. After baseline observations, pizza deliverers voted on a group turn-signal goal and then received 4 weeks of group feedback on their turn-signal use (i.e., group feedback phase). Then, for the next 4 weeks, individual turn-signal use means were publicly posted along with the group feedback (i.e., individual feedback phase). Deliverers at Store A (n = 24) increased their use of turn signals from a mean of 5% during baseline to 16.9% during the group feedback phase and then to 30% during the individual feedback phase.
