The purpose of this study was to differentiate women with three perimenstrual symptom severity patterns: premenstrual syndrome (PMS), premenstrual magnification (PMM), and low symptom (LS). Factors entered into the discriminant functions included social demands, personal resources, socialization, parity, age, personal health practices, and psychological distress. A community-based sample of 142 women taking no oral contraceptives was classified into one of the three symptom severity patterns. Three two-way discriminant analyses were performed. Women with PMS had more psychological distress, more education, and a mother with more premenstrual symptoms than those with an LS pattern. Women with PMM had more psychological distress and a mother with more premenstrual symptoms, but they also had more stress and were younger than those with an LS pattern. Finally, the women with PMS, when compared to the PMM subgroup, were older, had more education, engaged in more positive health practices, and had more nontraditional attitudes toward women. In addition, the women with PMM had more stress in their lives than women with PMS.
经前综合征（PMS）、经前放大（PMM）和低症状（LS）。纳入判别函数的因素包括社会需求、个人资源、社会化、产次、年龄、个人健康习惯和心理困扰。以社区为基础，对142名未服用口服避孕药的女性进行抽样，并将其分为三种症状严重程度模式之一。进行了三项双向判别分析。与LS模式的女性相比，PMS模式的女性有更多的心理困扰、受教育程度更高，且其母亲有更多的经前症状。PMM模式的女性有更多的心理困扰，其母亲有更多的经前症状，但与LS模式的女性相比，她们也有更多的压力且更年轻。最后，与PMM亚组相比，PMS模式的女性年龄更大、受教育程度更高、有更积极的健康习惯，且对女性有更非传统的态度。此外，PMM模式的女性生活中的压力比PMS模式的女性更大。
