Background Knowledge of how to improve consumer satisfaction with the outcome of co-production in services with high levels of interaction is important for achieving and maintaining a competitive advantage in the service industry. Objectives The aim of this paper is to review and meta-analyse research on the relationship between aspects of feedback to customers in interaction-intense encounters and the customer's satisfaction with the outcome. Methods We followed recommendations of the Cochrane Handbook for Systematic Review and Interventions to do a review and meta-analysis of relevant empirical research. From January 2018 to July 2018, we systematically searched PsycINFO, Business Source Complete, Science Direct and Web of Science for relevant studies. Results A total of six articles – consisting of 22 RCTs – were identified and included in the meta-analysis. Results indicate that feedback valence, with an effect size of 0.61 (0.43, 0.78), and feedback style, with an effect size of 0.82 (0.08, 1.57), have an impact on customers’ satisfaction with the outcome of co-production. For feedback interventions, effect size -0.29 (-0.69, 0.11), and feedback medium, effect size 0.43 (-0.00, 0.86), the results are inconclusive. Conclusions The present study suggest that there is a significant relationship between satisfaction with the outcome of co-production and feedback style and valence. To satisfy customers, service providers should offer positive feedback. In order to extend our knowledge, more studies on the effect of different feedback styles on customers' satisfaction with the outcome of co-production are needed.
