Predictors of health-related quality of life and participation after brain injury rehabilitation: The role of neuropsychological factors.

The aims of this longitudinal study were: (1) to assess associations between neuropsychological factors and health-related quality of life (HRQoL) and participation three months after discharge from inpatient acquired brain injury (ABI) rehabilitation; and (2) to determine the best neuropsychological predictor of HRQoL and participation after controlling for demographic and injury-related factors. Patients with ABI (n = 100) were assessed within approximately two weeks of enrolment in inpatient rehabilitation. Predictor variables included demographic and injury-related characteristics and the following neuropsychological factors: active and passive coping, attention, executive functioning, verbal memory, learning potential, depressive symptoms, motivation, extraversion, neuroticism and self-awareness. Bivariate analyses revealed that passive coping, executive functioning, depressive symptoms, extraversion, and neuroticism were significantly associated with HRQoL and/or participation. Neuropsychological factors significantly explained additional variance in HRQoL (18.1-21.6%) and participation (6.9-20.3%) after controlling for demographic and injury-related factors. However, a higher tendency towards passive coping was the only significant neuropsychological predictor (ß = -0.305 to -0.464) of lower HRQoL and participation. This study shows that neuropsychological functioning, and in particular passive coping, plays a role in predicting HRQoL and participation after inpatient ABI rehabilitation and emphasises the importance of addressing patients' coping styles in an early phase of ABI rehabilitation.

Awareness of memory functioning in patients with stroke who have a good functional outcome.

PRIMARY OBJECTIVE: To determine whether patients with stroke who have a good functional outcome show awareness of memory functioning and whether over- and under-estimation of memory performance are differentially related to neuropsychological performance. RESEARCH DESIGN: Prospective cohort study. METHODS AND PROCEDURES: The Barrow Neurological Institute Screen for Higher Cerebral Functions and a brief neuropsychological assessment were used to evaluate language, orientation, attention, visuospatial problem-solving, perception, reasoning, executive functioning, memory, affect and awareness of memory functioning. As for the latter, the patient's estimate of memory functioning was compared with his or her actual memory performance. Patients were divided into three groups: good-estimators (estimated performance = actual performance), over-estimators (estimated performance > actual performance) and under-estimators (estimated performance < actual performance). MAIN OUTCOMES AND RESULTS: In total, 54 patients with stroke were included, of whom 27 patients were classified as good-estimators, 19 as over-estimators and eight as under-estimators. Compared to good-estimators, over-estimators had significantly lower scores for all cognitive domains. Under-estimators had significantly poorer affect compared to good-estimators. CONCLUSIONS: These preliminary results suggest that over- and under-estimation of memory functioning can be observed in patients with stroke who have a good functional outcome and that they may reflect distinct underlying neuropsychological processes.
