Interdependence of stroke survivors' recovery and their relatives' attitudes and health: a contribution to investigating the causal effects.
OBJECTIVE
One goal of the study was to test specific hypotheses concerning the interdependence of the stroke survivors' recovery and their caregiving partners' attitudes and health. The other aim was to find an applicable method for investigating causal effects on the rehabilitation of chronically sick persons in longitudinal studies with medium-sized samples.


METHODS
The recovery of 81 stroke survivors regarding the physical and mental functioning in everyday life and their caregiving partners' health and attitudes were assessed twice, once after the patients left the hospital and again one year later. We applied the structure equation modeling and the cross-lagged partial correlation analysis (CLPC) for testing causal effects.


RESULTS
Particularly stroke victims' cognitive and emotional recovery seems to be influenced by psychosocial factors such as the caregiving partners' acceptance of a post-stroke life-situation. In contrast to this, the research suggests that the patients' recovery regarding physical functioning is not substantially affected by the partners, rather the patients' difficulties with motor functioning influence their partners' health.


CONCLUSIONS
Caregivers merit attention as part of rehabilitation interventions. We recommend the CLPC for investigating causal effects in the complex interdependence of chronically sick persons' convalescence and their family members' health and state of mind in medium-sized samples.
