M. Barkham et al., OUTCOMES OF TIME-LIMITED PSYCHOTHERAPY IN APPLIED SETTINGS - REPLICATING THE 2ND SHEFFIELD PSYCHOTHERAPY PROJECT, Journal of consulting and clinical psychology, 64(5), 1996, pp. 1079-1085
In a replication and extension of the Second Sheffield Psychotherapy P
roject (SPP2), a collaborative psychotherapy project (CPP) was carried
out at 3 sites within the National Health Service of the United Kingd
om. Clients (N=36) stratified at 3 levels of severity of depression we
re 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 clients did not maintain their gai
ns to the extent that the SPP2 clients did at 3-month and 1-year follo
w-up assessments. In the CPP clients given 16 sessions showed a statis
tically significant advantage over clients given 8 sessions on some me
asures at some assessments; in the SPP2, similar effects were noted on
ly among some subgroups of clients.
