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 (=-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.
