The recent explosion in advanced AI has led to the inevitable consideration of its role in psychological therapies, and mental health research in general. I will propose that integration of AI into psychotherapy requires a simple, practical, theoretical framework that unites disciplines of mathematics, engineering, computing, human-machine interaction, psychology, psychiatry, neuroscience, sociology, and the arts and humanities. Arguably, PCT is uniquely placed to serve this role. According to PCT, chronic, unresolved, psychological distress is a pervasive loss of control of key psychological and physiological variables. Restoration of control is established by providing access to fundamental biological and social resources ('dynamic catalysts for recovery'), and providing a safe environment for the exploration of chronic internal conflicts, held in conscious awareness until a higher level perspective, akin to a new 'gestalt' emerges, from which the issues with the conflict can be resolved. Given these assumptions, AI can provide a universal, scalable contribution to mental health recovery in a number of ways.
