The study design was cross-sectional. A mailed
questionnaire, developed with assistance from athletes
with disabilities and professionals working with
persons who had cognitive or physical disabilities,
was used. It was reviewed by a small sample from
the target group and remodeled twice. The questionnaire
was tested for test – retest reliability by a group
of 33 persons with the same types of disabilities as
the respondents of this study. The group completed
the questionnaire twice, 5 – 21 days apart. The questionnaire
showed substantial agreement with Cohen ’ s
kappa.
