NCT00927095

Brief Summary

The purpose of this study is to compare a low dose oral contraceptive (OC) given continuously (every day for three months) with the same low dose oral contraceptive given in an interrupted regimen (one week of inactive placebo pills each month) and with continuous placebo (inactive placebo given every day for three months). The primary hypothesis is that continuous OC will be significantly more effective in reducing premenstrual symptoms compared with either the interrupted OC or continuous placebo.

Outcome Measures

Primary Outcomes (1)

  • Pre-Post Change in Premenstrual Symptom Severity

    Pre-post change (pre minus post) in mean premenstrual week severity of the worst emotional symptom as measured using the Daily Record of Severity of Problems items 1-8. Worst symptom for each individual was defined as the symptom in the baseline month demonstrating the highest mean severity during the premenstrual week. Mean premenstrual week severity scores were calculated to correspond to mean ratings; therefore, the mean premenstrual severity values ranged as follows: 1=Not at All, 2=Minimal, 3=Mild, 4=Moderate, 5=Severe, 6=Extreme. The change variable presented here is calculated as follows: "mean rating on the individual's worst symptom during the premenstrual week at baseline" minus "mean rating during the premenstrual week during the last on-treatment cycle". Therefore, higher values on this outcome variable correspond to greater reductions in premenstrual symptoms across the trial.
