Greek Translation, Content Validity, Test-Retest and Inter-Rater Reliability of Swimming with Independent Measure (SWIM) Assessment Test for People with Disabilities Based on Halliwick Concept

Abstract

Objectives: Halliwick-based hydrotherapy has become one of the most widespread approaches in the water environment for people with disabilities. The Swimming with Independent Measure (SWIM) test was developed by Peackok (1993) based on the need to create specific aquatic assessment tests for people with disabilities. The purpose of our study was its translation into Greek language and the investigation of its metric properties. Methods: A total of 40 children with cerebral palsy aged on average 7.36 years participated in the study: 20 children with GMFCS 1 - 5 and cognitive limitations, and 20 children with GMFCS 1 - 4 without cognitive limitations. Two physiotherapists with extensive experience in hydrotherapy and Halliwick philosophy participated in the test-retest and inter-rater reliability and validity assessment. Results: The test-retest and inter-rater reliability for the overall score was found to be high (ICC = 0.99). In terms of validity, a positive correlation was found between SWIM and GMFM (r = 0.59). Conclusions: The Greek translation of the SWIM test was found to be highly reliable for assessing mental adaptation and functionality in the aquatic environment for children with disabilities, so it is recommended to professionals.
