[Sex as a variable in research in psychotherapy, psychosomatic and medical psychology].

All empirical studies (n = 113) published in "Psychotherapie, Psychosomatik, medizinische Psychologie" between 1988 and 1992 where analyzed concerning the question whether sex comparisons in at least one of the dependent variables were reported. The main results were that sex composition of the samples was not reported in 17% of the cases and that 62% of the studies did not report on sex comparisons. Only 25% of studies reported on sex differences in a metric which allows using this study for meta-analysis. Except for sample-size and sex-composition there were no study-features which distinguished between studies reporting or not reporting sex comparisons.
