title: Premenstrual syndrome and locus of control.
abstract: Seventy-six women completed a three-month prospective evaluation for premenstrual syndrome (PMS). As a part of the evaluation, they completed Rotter's Locus of Control (LOC) form in the follicular phase and premenstrually. It was found that the LOC scores of women meeting criteria for PMS rose significantly (became more "external") premenstrually, while scores of women without PMS did not show significant change. In addition, the premenstrual LOC scores of women meeting criteria for PMS were significantly higher than were scores of the non-PMS women. The results are consistent with the idea that cycle related changes in self-perception occur in women demonstrating PMS symptomatology.
