Reliability of the Danish version of the short questionnaire to assess health-enhancing physical activity (SQUASH)

ABSTRACT

Objective: To translate and cross-cultural adapt the short questionnaire to assess health-enhancing physical activity (SQUASH) to Danish, and to investigate the Danish version’s reliability. Methods: The study was conducted according to the COSMIN guidelines. The reliability was evaluated in 53 healthy subjects, mean age 47.1 ± 12.4 years and mean period 37.8 ± 14.8 days between test and retest. Results: For the total activity score ICC was 0.73 (0.57 to 0.83), SEM was 2316 (24% of the grand mean), and SDC was 6419 (67% of the grand mean). Conclusion: The relative reliability was acceptable and indicates that the Danish version of SQUASH can be used to distinguish between individuals; however, the absolute reliability was poor and SQUASH is not considered suitable for measuring physical activity on an individual level.
