ABSTRACT
The SALT-GAP (short-and long-term group analytic psychotherapy) project intended to address several areas of concern in contemporary group psychotherapy research. There has been a neglect of systematic small-and large-scale research studies, which has resulted in a scarce evidence base for the efficacy/effectiveness of psychodynamic therapies. Consequently there are too few high quality (randomized clinical trials) studies done, which is the gold standard in psychotherapy outcome research. There are also very few systematic studies of long-term group psychotherapy (group analysis), even though long-term groups are quite common in clinical practice.
