The Daily Assessment Form (OAF) retrospectively assessed symptoms of late luteal phase dysphoric disorder (LLPDD), both at the beginning and at the end of a 2-month time interval. Ninety-four women between the ages of 18 and 45 entered the study. Half of the subjects viewed a negative-case, stereotypic presentation of LLPDD prior to the pretest. sixty-eight subjects qualified on the pretest to complete the study. Half of the remaining no-case subjects and half of the remaining negative-case subjects completed 8 weeks' prospective ratings via the OAF. Forty-eight subjects remained to complete the posttest at the end of that time interval. Pretest Total and Pretest Criteria scores revealed significant main effects for case-presentation condition (E[l,63] = 7.08, R = .01) and (E[l,63] = 8.34, R = .01) and completion level (E[l,63] = 6.76, R = .01) and (E[l,63] = 3.76, R .06). Effect sizes equalled 0.48 and 0.45 for case presentation and 1.92 and 1.98 for completion.
