This descriptive, correlational study replicated an investigation by Selman (1989) exploring the effects of Total Hip Replacement (THR) on quality of life to identify adaptation level in the four effector modes of Roy\u27s Adaptation Model: physiologic function, self-concept, role function and interdependence. The convenience sample consisted of 43 subjects with a mean age of 67 electing to undergo primary TBR at one 410-bed midwestern medical center July, 1994 through December, 1994. Subjects were tested prior to undergoing THR and four months postoperatively. The instrument used was the Arthritis Impact Measurement Scales (AIMS) an arthritis-specific, self-administered questionnaire.; Analysis of data revealed a significant improvement postoperatively in the self-concept, physiologic function and role function subscales, which was consistent with the original study. There was also significant postoperative improvement in pain and arthritis activity scores. Married subjects reported significantly greater improvement on the arthritis visual analog scale than subjects without spouses
