Outcomes of time-limited psychotherapy in applied settings: replicating the Second Sheffield Psychotherapy Project.
In a replication and extension of the Second Sheffield Psychotherapy Project (SPP2), a collaborative psychotherapy project (CPP) was carried out at 3 sites within the National Health Service of the United Kingdom. Clients (N = 36) stratified at 3 levels of severity of depression were randomly assigned to one of 2 treatment approaches (psychodynamic-interpersonal or cognitive-behavioral) of 2 time-limited durations (8 or 16 sessions). Gains in both treatment approaches were approximately equivalent and were similar for CPP and SPP2 clients when measured at the end of treatment. However, CPP patients did not maintain their gains to the extent that the SPP2 clients did at 3-month and 1-year follow-up assessments. In the CPP, clients given 16 sessions showed a statistically significant advantage over clients given 8 sessions on some measures at some assessments; in the SPP2, similar effects were noted only among some subgroups of clients.
