Ho 6: Sensing types and intuitive types will not differ in the number of symptoms they reported on the Health History Questionnaire. This hypothesis was not rejected. Ho 7: Introverts and extraverts will not differ on the Health Locus of Control Scale. This hypothesis was rejected for the hand rehab. group. Ho 8: Coping styles will not account for differences on the McGill Pain Questionnaire. This hypothesis was rejected. To test the hypotheses I used a t test as one-way ANOVA for the individual groups and the SRTT for the total sample. Significant findings are 1. Feeling types chose more affective words than thinking types (p < .05) in the gastric bypass group. 2. Gastric bypass subjects with inhibited (p < .05) and the sensitive (p < .01) coping styles reported significantly higher pain at the time of testing than other groups. 3. Hand surgical patients with inhibited coping styles chose significantly more evaluative words (p < .05) than the other groups and also reported significantly more pain when tested (p < .01) than the other groups. 4. Hand surgical patients with forceful coping styles had significantly higher scores on the pain rating index sensory (p < .05), pain rating index miscellaneous (p < .05), and the pain rating index total (p < .05) than other groups. They also reported significantly more pain when tested (p < .01).
