Abstract
OBJECTIVES: To confirm, in a new sample, the value of our previously described procedure for identifying abnormal illness behaviour (AIB) in stroke rehabilitation patients, and to examine the relative effects of AIB, depression, family functioning, knowledge of stroke, and expectations of rehabilitation on long-term rehabilitation outcome. DESIGN: A longitudinal design, with assessments on admission to and discharge from rehabilitation, and six and twelve months after discharge. SETTING: The study was undertaken in the rehabilitation unit at Repatriation General Hospital, in Adelaide, South Australia. SUBJECTS: Sixty twelve-month stroke survivors, residing in a family environment, who had undergone an inpatient rehabilitation programme. MAIN OUTCOME MEASURES: AIB was assessed using the Illness Behaviour Questionnaire, depression with the Zung Self-Rating Depression Scale, family functioning with the McMaster Family Assessment Device, stroke knowledge with the Stroke Care Information Test, and expectations of rehabilitation with an open-ended question. Functional outcome was assessed with the competence and performance assessments of the Australian ADL Index, and lifestyle activities with the Frenchay Activities Index. RESULTS: Using our previously derived AIB classification rule, AIB cases scored poorly on functional, social and psychological indicators. Further, cluster analysis of discharge data replicated the rule for identifying patients with AIB. AIB was a strong predictor of functional competence and performance at rehabilitation discharge and both six and twelve months later, while depression was associated with an inactive lifestyle at both six and twelve months. Greater stroke knowledge and clearer expectations of rehabilitation were associated with better functional outcome at discharge. Family functioning was strongly associated with lifestyle activities and ADL performance at both six and twelve months. CONCLUSIONS: The procedure for identifying AIB in this rehabilitation environment appears to be robust. AIB was a key determinant of long-term functional disability, while depression was associated with poorer social functioning. Family functioning was an important determinant of social activities, and of the activities the patient actually does, rather than those the patient is capable of carrying out. Good stroke knowledge and clear expectations of rehabilitation were important determinants of rehabilitation success, and should be fostered to ensure a good rehabilitation outcome. Psychological factors are crucial in determining long-term outcomes after rehabilitation from stroke.
