investment model

a theory explaining commitment to a relationship in terms of one’s satisfaction with, alternatives to, and investments in the relationship. According to the model, commitment is a function of not only a comparison of the relationship to the individual’s expectations but also the quality of the best available alternative and the magnitude of the individual’s investment in the relationship; the investment of resources serves to increase commitment by increasing the costs of leaving the relationship. Although originally developed in the context of romantic associations and friendships and used to explain why people stay in abusive relationships, the investment model has since been extended to a variety of other areas, including employment and education. [proposed in 1980 by U.S. social psychologist Caryl E. Rusbult (1952–2010)]

trauma management therapy

trauma management therapy

a treatment program intended to alleviate the anxiety and fear, manage the anger, and enhance the interpersonal functioning of combat veterans with posttraumatic stress disorder (PTSD). It is a sequential multicomponent approach that combines (a) education, in which the client is informed about the symptom chronicity, skill deficits, and extreme social maladjustment associated with PTSD; (b) exposure therapy, in which the client reexperiences—in imagination or through virtual reality—his or her specific traumatic event during individually administered weekly sessions; (c) programmed practice, in which the client performs exposure-related homework assigned by the therapist; and (d) socioemotional rehabilitation, in which the client participates in structured, group-administered social and emotional skills training sessions. [developed in 1996 by clinical psychologists B. Christopher Frueh (1963–  ), Samuel M. Turner (1944–2005), Deborah C. Beidel, and Robert F. Mirabella and health administrator and political scientist Walter J. Jones]
