Abstract
The purpose of this study was to determine whether the effects of stressful life events on perimenstrual symptoms were due to operational confounding of the instruments used to measure the independent and dependent variables. Women aged 18 to 35 (n = 179) completed the Schedule of Recent Events (SRE) and the Moos Menstrual Distress Questionnaire during a home interview. When variance in PMS scores attributable to age, parity, education, and contraceptive method was controlled using hierarchical multiple regression, total SRE scores were correlated with premenstrual and menstrual negative affect, menstrual water retention, and menstrual performance impairment. When health-related components of the SRE score were controlled in a similar manner, however, the residual SRE scores explain a diminished amount of the variance in premenstrual and menstrual negative affect and menstrual performance impairment. Future investigations are needed to clarify whether the effects of health-related life events on perimenstrual symptoms are simply a matter of operational confounding of measures of the independent and dependent variables, or whether women who recently have experienced personal illness or injury are at greater risk of developing perimenstrual symptoms.
