Abstract
How can gratitude interventions be designed to produce meaningful and enduring effects on people's well-being? To address this question, the author proposes the Catalyst Model of Change-this novel, practical, and empirically testable model posits five socially oriented behavioral pathways that channel the long-term effects of gratitude interventions as well as how to augment gratitude experiences in interventions to boost treatment effects and catalyze these behavioral pathways. Specifically, interventions that enhance the frequency, skills, intensity, temporal span, and variety of gratitude experiences are likely to catalyze the following post-intervention socially oriented behaviors: (a) social support-seeking behaviors, (b) prosocial behaviors, (c) relationship initiation and enhancement behaviors, (d) participation in mastery-oriented social activities, and (e) reduced maladaptive interpersonal behaviors, which, in turn, produce long-term psychological well-being. A unique feature of the Catalyst Model of Change is that gratitude experiences are broadly conceptualized to include not just gratitude emotions, cognitions, and disclosures, but also expressing, receiving, witnessing, and responding to interpersonal gratitude. To this end, gratitude interventions that provide multiple opportunities for social experiences of gratitude (e.g., members expressing gratitude to each other in a group) might offer the greatest promise for fostering durable, positive effects on people's psychological well-being.
