In the present study, eleven adult women diagnosed with MPD provided samples written by alternate identities or personality states (alters). Four inconspicuous handwriting characteristics were measured with electronic calipers under magnification. Analysis of the handwriting measures with one-way ANOVAs determined that most MPD subjects showed significantly more variability in handwriting samples produced by different alters than would be expected from different samples produced by the same person. These differences between handwriting measures of different alter personalities were neither as frequent nor as large as those between separate individuals in most cases. Clinical information on MPD subjects was analyzed for factors which contributed to the occurrence of handwriting variations, but no consistent pattern was found.576398 bytesapplication/pdfen-USArticle
