A study was conducted comparing an Educational Support Group (N = 5) with a Waiting-List Control Group (N = 5) in the treatment of Premenstrual Dysphoric Disorder (PMDD). Subjects met diagnostic criteria for PMDD as outlined by the DSM-IV (1994). It was hypothesized that the educational support group would exhibit less severe symptoms of PMDD than the control group as a function of exposure to educational support. To measure changes between the groups, (across the one month pre-treatment, two month treatment, and one month post treatment phase) the Premenstrual Assessment Form, the Daily Record of Severity of Problems (content specific to the DSM-IV criteria for PMDD), and a Daily Monitoring Form were utilized The hypothesis that educational support would decrease PMDD symptoms was not supported by the results of this study. However, there appeared to be an advantage to participating in an educational support group as was determined by responses to a Final Questionnaire
