For convergent validity ( i.e. , the relationship between PAQs and other measures ) , similar overall associations were found between Past-week PAQs and Usual-week PAQs .
However , PAQs were more strongly associated with direct measures of physical activity ( e.g. , accelerometer ) than indirect measures of physical activity ( i.e. , physical fitness ) , irrespective of recall methods .
Only a few interview-administered PAQs exhibited positive ratings for a single psychometric property , although the other properties were either rated as poor or question able , demonstrating the limitations of current PAQs .
The Physical Activity Scale for the Elderly (PASE): development and evaluation.
A Physical Activity Scale for the Elderly ( PASE ) was evaluated in a sample of community-dwelling , older adults . Respondents were r and omly assigned to complete the PASE by mail or telephone before or after a home visit assessment . Item weights for the PASE were derived by regressing a physical activity principal component score on responses to the PASE . The component score was based on 3-day motion sensor counts , a 3-day physical activity dairy and a global activity self- assessment . Test-retest reliability , assessed over a 3 - 7 week interval , was 0.75 ( 95 % CI = 0.69 - 0.80 ) . Reliability for mail administration ( r = 0.84 ) was higher than for telephone administration ( r = 0.68 ) . Construct validity was established by correlating PASE scores with health status and physiologic measures . As hypothesized , PASE scores were positively associated with grip strength ( r = 0.37 ) , static balance ( r = + 0.33 ) , leg strength ( r = 0.25 ) and negatively correlated with resting heart rate ( r = -0.13 ) , age ( r = -0.34 ) and perceived health status ( r = -0.34 ) ; and overall Sickness Impact Profile score ( r = -0.42 ) . The PASE is a brief , easily scored , reliable and valid instrument for the assessment of physical activity in epidemiologic studies of older people
