An attributional approach to moods and the menstrual cycle.

Acceptance of an attribution pattern linking negative moods (depression, irritability) to the approach of menstruation and the likelihood of internal and external attributions were examined in a questionnaire study in which cycle phase (pre- versus postmenstrual), mood (positive versus negative), and environment (pleasant versus unpleasant) were varied. Subjects' rating indicated that (a) biology was judged important for explaining negative moods occurring premenstrually: (b) inconsistency between mood and environment produced more internal (personality) attributions, while consistency enhanced external attributions; and (c) emotionally expressive behavior was thought to reflect underlying personality dispositions despite extenuating situational factors (assumed personal causation). The theoretical relevance of the findings to a new conceptualization of premenstrual emotionality and to an attributional chain relating female self-concept and premenstrual tension is discussed.
