Observations on the handedness preferences of patients with personality disorders

A new series of patients with personality disorders has provided an opportunity to extend to both sexes an earlier finding that personality disordered women tend to be mixed handed. Eighty-one subjects completed Annett's handedness questionnaire. The frequency of mixed hand preference in both sexes was similar to that found in the previous study, though deviations from consistent preference were small and dependent on the method used to classify handedness. The hysterical, antisocial and explosive personality types were particularly likely to have mixed handedness. These associations were reflected in small but significant trends among several psychometric variables.
