Positive Psychology and Brain Injury Systems

Abstract Abstract This chapter explores the integration of strengths-based approaches within rehabilitation and counseling psychology, challenging the predominant deficit model in traditional brain injury rehabilitation. The chapter explores the promising application of positive psychology tools in brain injury research, emphasizing the modulation of positive affect and capitalization on individual strengths. It expands the scope of well-being beyond traditional concepts, incorporating eudaimonic aspects such as engagement, personal growth, meaning-in-life, and self-acceptance in the context of brain injury. While not strictly positive psychology, acceptance and commitment therapy is discussed, particularly in its application to values-based action, aligning with historical values changes in rehabilitation psychology. The chapter also highlights the evolving understanding of resilience as a dynamic adaptation process following brain injury, with trajectory models indicating many individuals demonstrating resilience. Further research utilizing positive psychology constructs is advocated to explore positive adjustment indices after brain injury.
