Previous research that related lunar phase to abnormal behavior has led to apparently conflicting findings because of different methodology. The present study, based upon both new data and that already in the literature, combined studies that used the same segments of the synodic cycle. Such analysis indicated a disproportionate frequency of abnormal behavior at the time of the new moon, at the time of the full moon, and in the last half of the lunar phase. These findings were regarded as generally congruent with folklore.
