Questionnaire test-retest reliability: outcome measure of a vocational rehabilitation programme.
In a clinical follow-up case series study, the test-retest reliability of an outcome measure questionnaire was tested. The study group consisted of 48 patients who had taken part in a vocational rehabilitation programme. Test-retest reliability of a questionnaire was evaluated with the reliability index two years after entering the programme. It was found that the test-retest reliability of demographic data was rather good, although the questions concerning basic and occupational training showed instability over time. The answers concerning general health symptoms, mental working capacity and perceived changes in life during the past 12 months showed particularly high variability. The respondents' opinions on their general outlook of life seemed rather stable. Opinions about the perceived benefits from the intervention were marginally stable. The respondents' opinions about the benefits perceived from the physicians' work were more stable than the opinions about the perceived help from the other members of the rehabilitative team. It was concluded that an outcome analysis questionnaire is a useful tool to document the respondents' general and present perception of life and their present health situation as well as the rehabilitation process. The further development of generally applicable outcome measures for health promotion programmes will require unified, long-term efforts.
