various forms of treatment and psychoeducation—including psychotherapy and behavior modification, among others—aimed at increasing an individual’s adaptive and independent mental and behavioral functioning. Psychological treatment is the specific purview of trained mental health professionals and incorporates diverse theories and techniques for producing healthy and adaptive change in an individual’s actions, thoughts, and feelings. It stands in contrast to treatment with medication, although medication is sometimes used as an adjunct to various forms of psychological treatment (see adjunctive therapy).
