Background And Purpose:
The purpose of this study was to examine the psychometric properties of the Patient Assessment of Own Functioning Inventory (PAOFI) following aneurysmal subarachnoid hemorrhage (aSAH).
Methods:
The PAOFI was completed by 182 participants 3 months after verified aSAH. Exploratory factor analysis was used to evaluate the underlying factor structure of the PAOFI and reliability and concurrent validity were evaluated for each subscale.
Results:
A three-factor structure accounted for 58.9% of the extracted variance. Cronbach's alpha coefficients for extracted factors ranged from .867 to .924. The PAOFI subscales demonstrated concurrent validity with neuropsychological tests measuring similar constructs.
Conclusion:
There is evidence of reliability and validity of the PAOFI following aSAH. Further studies are needed to confirm these results.
