Measurement properties of the CHAMPS physical activity questionnaire in a sample of older Australians
ABSTRACT The effective evaluation of physical activity interventions for older adults requires measurement instruments with acceptable psychometric properties that are sufficiently sensitive to detect changes in this population.
To assess the measurement properties (reliability and validity) of the Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire in a sample of older Australians.
CHAMPS data were collected from 167 older adults (mean age 79.1 S.D. 6.3 years) and validated with tests of physical ability and the SF-12 measures of physical and mental health. Responses from a sub-sample of 43 older adults were used to assess 1-week test-retest reliability.
Approximately 25% of participants needed assistance to complete the CHAMPS questionnaire. There were low but significant correlations between the CHAMPS scores and the physical performance measures (rho=0.14-0.32) and the physical health scale of the SF-12 (rho=0.12-0.24). Reliability coefficients were highest for moderate-intensity (ICC=0.81-0.88) and lowest for vigorous-intensity physical activity (ICC=0.34-0.45). Agreement between test-retest estimates of sufficient physical activity for health benefits (> or =150min and > or =5 sessions per week) was high (percent agreement=88% and Cohen's kappa=0.68).
These findings suggest that the CHAMPS questionnaire has acceptable measurement properties, and is therefore suitable for use among older Australian adults, as long as adequate assistance is provided during administration.

ABSTRACT: This study examined the effect of dancing on the functional performance and physical activity levels of 45 retirement village residents participating in either a control (n = 13), Once a Week (n = 18) or Twice a Week (n = 14) dance group for 12 weeks. Changes in functional performance were assessed by three functional tests (30 s bicep curl, Timed Up and Go and the Four Square Step Test) as well as the Late Life Function Index. The CHAMPS questionnaire was used to estimate the weekly total as well as moderate and greater intensity energy expenditure and associated frequency counts. Once a Week dancing resulted in significantly greater improvements in Four Square Step Test and estimated total energy expenditure than the control group; whereas the Twice a Week group significantly improved their Late Life Function Index (Total and Basic Lower Extremity) scores significantly more than the control group (p<0.05). No significant between-group differences were observed in the changes for the two dance groups (p>0.05). These results further support the belief that even once a week exercise (including dancing) can produce some significant benefits for older adults.

ABSTRACT: This study describes moderate to vigorous physical activity (MVPA) and sedentary behavior among New York City (NYC) residents 60 years and older and compare to national United States' estimates. Adults aged 60 or older living in NYC (n=760) were compared to similar aged adults from the National Health and Nutrition Examination Survey (NHANES) (n=2451 adults). Both groups wore an ActiGraph accelerometer for one week. The NYC sample recorded 13.2, 23.8, and 37.8 mean minutes/day of MVPA and the NHANES sample recorded 10.6, 21.1, and 39.3, depending on the definition. Sedentary behavior averaged 9.6 hours/day for the NYC sample and 9.3 hours/day for the NHANES sample. The NYC sample spent a longer proportion of time in sedentary behavior and light activities, but more time in MVPA than the NHANES sample. Urbanicity may explain some of the differences between the two samples.Journal of Aging and Physical Activity 10/2013; 22(4). DOI:10.1123/JAPA.2012-0345 · 1.41 Impact Factor

ABSTRACT: The purpose of this study was to establish validity evidence of four physical activity (PA) questionnaires in culturally diverse older adults by comparing self-report PA with performance-based physical function. Participants were 54 older adults who completed the Continuous Scale Physical Functional Performance 10-item Test (CS-PFP10), Physical Activity Scale for the Elderly (PASE), CHAMPS Physical Activity Questionnaire for Older Adults, Yale Physical Activity Survey (YPAS), and modified Baecke questionnaire. The total PASE score, three outcome scores for the CHAMPS, and three summary indices for the YPAS were significantly correlated with total CS-PFP10 score. The modified Baecke exhibited no correlations with CS-PFP10 scores. The PASE, CHAMPS, and YPAS appear to be the most valid PA self-report questionnaires for culturally diverse older adults.Research quarterly for exercise and sport 01/2013; 79(1):42-50.
