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 .
Development of Questionnaire to Examine Relationship of Physical Activity and Diabetes in Pima Indians
There was a need to design a question naire that could accurately assess the activity patterns of Native Americans to evaluate the relationship between physical activity and diabetes . Such a question naire was developed and implemented into the data collection scheme of the prospect i ve Pima Indian Study of Arizona . The question naire , which assesses historical , past-year , and past-week leisure and occupational activity , was examined in 29 Pima individuals aged 21–36 yr and was shown to be reliable with test-retest correlations ( rank-order correlations ranged from 0.62 to 0.96 for leisure and occupational activity ) . Reproducibility of the past-year leisure physical-activity estimate was determined in 69 participants aged 10 - 59 yr and was found to be reliable in all age-groups with the exception of the 10- to 14-yr-old age-group ( rank-order correlations were 0.31 in the 10- to 14-yr-old age-group compared to 0.88 to 0.92 in those > 20 yr of age ) . Validity of the current-activity section of the question naire was demonstrated indirectly through comparisons with activity monitors . The past-week leisure-activity estimate was related to the Caltrac activity monitor counts per hour ( p = 0.62 , P > 0.05 , n = 17 ) . In summary , a physical-activity question naire has been developed that is both reliable and feasible to use in the Pima Indian population to evaluate the relationship of physical activity to non-insulin-dependent diabetes mellitus
