117 Ho 8: Coping styles will not account for differences on the McGill Pain Questionnaire. In testing this hypothesis I used a one-way analysis of variance of the Millon coping styles on the scales of the McGill Pain Questionnaire. The results for the gastric bypass group showed significant differences in the inhibited group (p < .05) and the PPI and the sensitive group (p < .01) on the PPI. In the hand surgical group significant differences occurred in the inhibited group in the PRIE scale (p < .05) and the PPI scale (p < .01), the forceful group on the PPI scale (p < .01), the forceful group on the PRIT (p < .05), the PRIS (p < .05), the PRIM (p < .05) scales, and the sensitive group on the PRIE (p < .05). In the hand rehab. group significant results were found with intraversive coping style on the PRIM scale (p < .05), respectful style on the PPI scale (p < .05), and sensitive style on the NWCS scale (p < .05). Therefore, the null hypothesis that coping styles will not account for differences on the McGill Pain Questionnaire is rejected. Results of the ANOVAs can be found in Tables 4-60, 4-61, and 4-62. Summary In an analysis of the scales of the Myers-Briggs Type Indicator and the Millon Behavioral Health Inventory on the McGill Pain Questionnaire I tested eight hypotheses to determine if the personality scales were related to pain response and if differences existed between the personality variables on various scales of the MPQ.
