Few studies reported in the literature examine the relationships among mood, psychosocial attributes, and outcome in a rehabilitation setting. There is a need for determining an empirical relationship between attitudinal/emotional responses to rehabilitation and subsequent outcome. The present study was designed to develop a model that could describe patterns of response to rehabilitation. Cluster analysis was used to determine whether there were specific, identifiable groups that differed with respect to self-reported assessment of depression, expectation for success, and determined source of attribution for health. Three groups were identified with statistically and clinically significant differences between them. The conclusions of this study indicate that the three spheres of depression, attribution, and expectation could be used to develop an empirically based model that describes the patient's response to rehabilitation. Continued research is needed to validate these findings further and to determine optimal intervention strategies for the rehabilitation patient.
