Reliabilities of the Groningen Functional Capacity Test.

The purpose of this study was to make a preliminary evaluation of the test-retest reliability of the Groningen Functional Capacity Test, a test developed to assess the functional capacity of people with a chronic disease and/or physical handicap and participating in a recreational sports stimulation program called SCALA, as a way to create homogeneous sport groups. The test includes motor actions typical for the SCALA sports program and has eight subtests, reaching, balancing, ball-catching, picking up objects, ball-kicking, ball-throwing accuracy, tennis, and walking. The subjects were 52 adults aged 46-71 years, randomly selected from the SCALA project. Intraclass correlations ranged from .96 to .58. Two subtests showed significant improvements on retest for walking (total sample and men) and picking up (total sample, men, and women). For most subtests, test-retest reliability was satisfactory and therefore worth being implemented in the SCALA program.
