title: [The effectiveness of open and closed groups].
abstract: Studies of four closed and four open groups of patients participating in psychotherapy, which were conducted in a psychotherapeutic inpatient department using pre- and post-test diagnoses (the test used being the MMPI, FPI, Q-Sort, and Giessen tests), showed that these were not different as regards the frequency of statistically evident changes recorded upon the completion of psychotherapy. The authors also discuss the advantages and disadvantages of open and closed groups, with particular consideration being given to organizational aspects.
