relations theory, self psychology, interpersonal psychoanalysis, and relational psychoanalysis. Techniques for analytic group therapy have also developed. Cognitive-behavioral Behavior therapies use behavioral techniques, including applied behavior analysis (also known as behavior modification), to change maladaptive patterns of behavior to improve emotional responses, cognitions, and interactions with others. Functional analytic psychotherapy is one form of this approach. By nature, behavioral therapies are empirical (data-driven), contextual (focused on the environment and context), functional (interested in the effect or consequence a behavior ultimately has), probabilistic (viewing behavior as statistically predictable), monistic (rejecting mind-body dualism and treating the person as a unit), and relational (analyzing bidirectional interactions). Cognitive therapy focuses directly on changing the thoughts, in order to improve the emotions and behaviors. Cognitive behavioral therapy attempts to combine the above two approaches, focused on the construction and reconstruction of people's cognitions, emotions and behaviors. Generally in CBT, the therapist, through a wide array of modalities, helps clients assess, recognize and deal with problematic and dysfunctional ways of thinking, emoting and behaving. The concept of "third wave" psychotherapies reflects an influence of Eastern philosophy in clinical psychology, incorporating principles such as meditation into interventions such as mindfulness-based cognitive therapy, acceptance and commitment therapy, and dialectical behavior therapy for borderline personality disorder. Interpersonal psychotherapy (IPT) is a relatively brief form of psychotherapy (deriving from both CBT and psychodynamic approaches) that has been increasingly studied and endorsed by guidelines for some conditions. It focuses on the links between mood and social circumstances, helping to build social skills and social support. It aims to foster adaptation to current interpersonal roles and situations. Exposure and response prevention (ERP) is primarily deployed by therapists in the treatment of OCD. The American Psychiatric Association (APA) state that CBT drawing primarily on behavioral techniques (such as ERP) has the "strongest evidence base" among psychosocial interventions. By confronting feared scenarios (i.e., exposure) and refraining from performing rituals (i.e., responsive prevention), patients may gradually feel less distress in confronting feared stimuli, while also feeling less inclination to use rituals to relieve that distress. Typically, ERP is delivered in "hierarchical fashion", meaning patients confront increasingly anxiety-provoking stimuli as they progress through a course of treatment. Other types include reality therapy/choice theory, multimodal therapy, and therapies for specific disorders including PTSD therapies such as cognitive processing therapy and EMDR; substance abuse therapies such as relapse prevention and contingency management; and co-occurring disorders therapies such as
