Abstract
Background:
The aim of this study was to address the ability of the recovery locus of control
scale (RLOC) and post-traumatic stress symptoms (PTSS) to predict physical functioning among
stroke patients. In addition, the best predictors within the subdomains of the RLOC and PTSS were
also investigated.
Methods:
A total of 147 stroke patients aged 33–85 years who had intact cognitive functioning
were involved in the study. The Recovery Locus of Control Scale (RLOC), the Impact of Event Scale-
Revised (IES-R), and the Barthel Index (ADL) were administered to respondents six weeks after
stroke.
Results:
The results showed that the RLOC and PTSS were significant predictors and
were capable of predicting 31% of the physical functioning of stroke patients (adjusted R2 = 0.31;
P < 0.001). Furthermore, with respect to clinical factors, the affected lesion side contributed to
predicting 7% of the physical functioning (R2 = 0.07; P < 0.001). A hierarchical regression analysis
found that the internal recovery locus of control (IRLOC) was a predictor capable of explaining 18%
of the predicted physical functioning (adjusted R2 = 0.18; P < 0.001). Meanwhile, avoidance was the
most influential significant predictor among PTSS, contributing to 24% of the predicting physical
functioning (adjusted R2 = 0.24; P < 0.001).
Conclusion:
In conclusion, the RLOC and PTSS were capable of predicting physical
functioning among stroke patients.
