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.

- "All eligible participants will be informed individually about the content of the intervention and the study design will be explained. The participants will be asked to complete the Community Healthy Activities Model Program for Seniors (CHAMPS) that assessed the intensity and the frequency of their participation in various activities such as walking, gardening, housework, sports activities, and volunteering . After that, participants will be randomly allocated into either the experimental group (DT-TW) or the control group (DT-RC) (Figure 1). "
ABSTRACT: Background: Mobility limitations and cognitive impairments which are common with ageing often coexist, causing a reduction in the levels of physical and mental activity and are prognostic of fu- ture adverse health events and falls. Consequently, multi-task training paradigms that simultane- ously address both mobility and cognition benefit healthy ageing are important to consider in re- habilitation as well as primary prevention. Objectives: An exploratory RCT is being conducted to: a) describe the feasibility and acceptability of the study design and process, procedures, resources and management in two game-based dual-task training programs delivered in the community; b) to explore the lived experiences of the study participants who completed their respective exercise programs. A secondary objective is to obtain preliminary data on the therapeutic effectiveness of the two dual-task training programs. Methods: Thirty healthy older community dwelling partici- pants aged 70 - 85 with previous history of falls will be recruited and randomized to either dual- task treadmill walking (experimental group) or dual-task recumbent bicycle (control group). Data analysis: The qualitative data will be analyzed by two investigators using a content analysis ap- proach. For the quantitative data, outcome measures will be collected pre and post intervention and included measures to assess core balance, spatial-temporal gait variables, visual tracking and cognitive function, as well as, balance and gait analysis under dual-task conditions. Discussion:This research will demonstrate the feasibility of the dual-task training programs in the commu- nity, and demonstrate the system’s ability to improve targeted and integrated (dual-task) aspects of balance, mobility, gaze, and cognitive performance. A blended analysis of balance, mobility gaze and cognition will also contribute to a better understanding of the functional consequences of de- cline in physical and mental skills with age. Trial registration: This pilot clinical trial has been registered at ClinicalTrials.gov Protocol Registration System: NCT01940055.Advances in Aging Research 05/2015; 4(3):96-111.

- ". If participants reported doing any of the listed activities, they were asked to record the number of occasions the activity was normally performed per week and the average duration of that activity. A research assistant was available to assist the older adults completing the CHAMPS (as well as the LLFI) questionnaires if required, as such assistance was required in up to 25% of retirement village residents . "
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.

- "Both kcal expenditure measures were computed using the CHAMPS instrument, designed to quantify relative kcal expenditure in adult populations based on self-reported frequency and duration of a range of common physical activities (Stewart, et al., 2001). CHAMPS-calculated kcal expenditure has demonstrated acceptable reliability, with ICCs for moderate intensity activities of 0.67, 0.76, and 0.81–0.88 at six months, two weeks, and one week, respectively (Stewart, et al., 2001, Cyarto, et al., 2006). The instrument has also demonstrated adequate discriminant and construct validity, correlates well with other measures of PA, and is sensitive to change (Stewart, et al., 2001). "
ABSTRACT: To evaluate the efficacy at 6-, 12-, and 24-month follow-up of Keep Active Minnesota (KAM), a telephone and mail-based intervention designed to promote physical activity (PA) maintenance among currently active adults age 50 to 70. Participants who reported having recently increased their MVPA to a minimum of 2d/wk, 30 min/bout, (N=1049) were recruited in 2004 and 2005 from one large managed care organization in Minnesota, and randomly assigned to either treatment (KAM; N=523), or Usual Care (UC; N=526) with PA assessed using the CHAMPS questionnaire, and expressed as kcal/wk energy expenditure. We find a sustained, significant benefit of the intervention at 6, 12 and 24 months. kcal/wk expenditure in moderate or vigorous activities was higher at 6 (p<.03, Cohen's d(6m)=.16), 12 (p<.04, d(12 m)=.13) and 24 months (p<.01, d(24 m)=.16) for KAM participants, compared to UC participants. The KAM telephone- and mail-based PA maintenance intervention was effective at maintaining PA in both the short-term (6 months) and longer-term (12 and 24 months) relative to usual care.Preventive Medicine 04/2010; 51(1):37-44.
