The psychobiological approach to couples therapy focuses on understanding the underlying physiological and psychological factors influencing relationship dynamics. This approach integrates principles from neuroscience, attachment theory, and interpersonal neurobiology to explore how the brain and body contribute to relationship patterns and interactions. Therapists using this approach may assess factors such as stress responses, emotional regulation, and attachment styles to help couples understand and address their relational challenges. By considering the interplay between biology, emotions, and behavior, psychobiological couples therapy aims to promote empathy, enhance communication, and foster healthier relationship dynamics.
