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 .
Assessment of habitual physical activity by a seven-day recall in a community survey and controlled experiments.
Assessment of habitual physical activity in epidemiologic and health education studies has been difficult . A seven-day physical activity recall interview was developed and administered in a community health survey , a r and omized clinical trial , and two worksite health promotion programs during 1979 - 1982 . These studies were conducted in several population s in California , Texas , Pennsylvania , and New Jersey . Energy expenditure estimates from the physical activity recall conformed to expected age- and sex-specific values in the cross-sectional community survey . Estimates of energy expenditure were also congruent with other questions on physical activity and job classification . In a r and omized , one-year exercise trial , the physical activity recall detected increases in energy expenditure in the treated group and was positively associated with miles run during training ( p less than 0.05 ) . Changes in energy expenditure were associated with changes in maximal oxygen uptake ( VO2max ( r = 0.33 , p less than 0.05 ) and body fatness ( r = -0.50 , p less than 0.01 ) at six months , and in high density lipoprotein-cholesterol ( r = 0.31 , p less than 0.05 ) and triglyceride ( r = -0.41 , p less than 0.01 ) at one year . The physical activity recall detected significant ( p less than 0.01 ) increases in energy expenditure in treatment groups in two worksite health promotion projects . These data suggest that the physical activity recall provides useful estimates of habitual physical activity for research in epidemiologic and health education studies
