I’m studying for my Psychology class and need an explanation.

Application: Time-Limited Dynamic Psychotherapy—Case Conceptualization

The field of psychotherapy is moving in a direction where short-or brief-term therapies are in high demand. The reasons for this shift in therapeutic "time" perspective include, to name a few, the evolution and revision of theory that allows the shortening of the typical therapeutic time frame, pressure from managed care organizations to shorten the number of covered psychotherapy sessions, and the adaptation of psychodynamic theory to environments beyond private practice or psychoanalysis. This week, you examine time-limited dynamic psychotherapy (TLDP), a short-term psychodynamic therapy considered more medium-term length than other therapeutic approaches espousing a "short-term" focus.
In this Application Assignment, you evaluate Case Study: Sam through the lens of time-limited dynamic psychotherapy. Developing a comprehensive case conceptualization is a challenging exercise that requires you to integrate what you know about the client with what you understand about a theory and apply that information to a working treatment plan. This process requires you to develop a preliminary diagnosis and to evaluate the unique contextual considerations each client brings to treatment, in this instance, Sam, from this week's case study. Because case conceptualization is such a complex process, a Case Conceptualization Exemplar is provided as a guide.

To prepare for this assignment:

Review the "Psychodynamic Approaches" sections on the DVD, Counseling: Theories in Action. Pay particular attention to the methods used by the therapists to gather information related to their clients' presenting issues. Discern some of the basic techniques associated with psychodynamic and brief therapies.
Review Dr. Norcross' course media presentation "Psychodynamic Orientation Foundations". Pay particular attention to his discussion on short or brief psychodynamic therapies.
Review Case Study: Sam and begin to develop a preliminary diagnosis of Sam's presenting problems.
Download and familiarize yourself with the Case Conceptualization Exemplar and the Case Conceptualization Template.
