Abstract
Background: Functional performance plays an important role in the independence and participation of people with severe psychiatric disorders. The Bay Area Functional Performance Evaluation-Task-Oriented Assessment (BaFPE-TOA) is a tool that evaluates functional performance. The present study aimed to assess the convergent validity and inter-rater reliability of the BaFPE-TOA tool using the classic test theory.
Methods: In this psychometric study, the population comprised people with severe psychiatric disorders. Participants were selected according to the inclusion criteria and convenience sampling. Consent to participate in the study was given by all participants. To examine the convergent validity, two tests, the BaFPE-TOA test and Kohlman Evaluation of Living Skills (KELS) test, were performed for 55 patients. To assess the inter-rater reliability, two examiners (occupational therapists) performed the BaFPE-TOA test for 26 patients simultaneously. Then, the Pearson correlation coefficient was used to examine convergent validity, and the intraclass correlation coefficient was used to assess inter-rater reliability.
Results: Participants in this study comprised 44 men (81.8%) and 10 women (18.2%). The age of participants ranged from 22 to 69 years with a mean of 41.5 years (SD = 10.5). The Pearson correlation coefficient between the BaFPE-TOA and the KELS was good (r=0.74, p -value <.001). The Intraclass correlation coefficient and Pearson correlation coefficient between the two examiners showed a good relation (r= 0.75, p -value <0.001).
Conclusion: The results showed that the Persian version of the BaFPE-TOA has acceptable convergent validity with KELS and inter-rater reliability that represents the suitability of this tool for use in the healthcare environment.
