The Portuguese Performance Assessment of Self-Care Skills Measure: Validity and Reliability

Abstract

Performance Assessment of Self-Care Skills (PASS) is a performance-based scale developed in the United States. Because of cultural differences, a Portuguese version was developed, then validated in the Portuguese population and tested ensuring reliability. The objective of this study was to create and test psychometric properties of a Portuguese version of PASS. A linguistic validation on older adults with physical/cognitive disabilities enabled us to validate P-PASS. Some original tasks were changed. Data were analyzed by PASS constructs (independence-safety adequacy), age, and gender. Construct validity (known-group analyses, factor analyses), with 98 individuals yielded excellent results. Reliability between two observers for 30 participants yielded almost perfect agreement for all three constructs. Independence scores were highest, followed by safety and adequacy. Men presented greater independence, as well as participants <60 years. We obtained results comparable with the original version. Conclusion. P-PASS is valid and reliable for the Portuguese population, enabling effective assessment of function and measurement of health outcomes.
