Reliability of Physical Activity Pattern Questionnaire for Elders
By cho MH
Abstract Background Since it is important for elders to do physical activity regularly, many countries including South Korea have followed physical activity recommendations on the dose-response relationship between the frequency, duration, intensity, and type of physical activity for health. Although many studies have focused on the dose-response relationship of physical activity with health benefits for older adults, there is little information available and practical to measure physical active lifestyle whether they meet the recommendations of physical activity.Objective The purpose of this study is to assess the test-retest reliability of the newly developed physical activity pattern questionnaire in repeated assessments performed by older adults aged 65 years and above.Methods Of the 200 questionnaires, 117 residents aged over 65 who were participating in recreational programs provided by the community centers (senior center, residential culture center, and sport center) completed the survey. The test-retest repeatability was assessed using the Cohen’s kappa statistics.Results The reliability coefficient showed good to high internal consistency throughout. The alpha statistic was 0.658 for questions on flexibility activity participation, 0.666 for questions on aerobic activity participation, and 0.935 for questions on muscular activity participation.Conclusions This paper made an important methodological contribution to the assessment of physical activity by showing that when creating a more accurate and comfortable tool for measuring physical activity it is necessary to take into account the global physical activity recommendations. In conclusion, the author found excellent or good reproducibility at a four week interval for all questions that survey physical activity pattern among elders and know whether they meet the global physical activity recommendations.
