Wolf et al. 1994

See reference #48

Methods

Relation between NHS II-PAQ and past-week activity recalls and 7-day activity diaries (deattenuated correlations adjusted for within-person variation)

Sample

Representative sample of 149 women (84 African American) from NHS II; 39 ± 4.3 years of age

Summary Results

Correlation of NHS II PAQ verses average response on 4 past week recalls

	crude	deattenuated
Representative Sample	0.70 (0.60-0.77)*	0.79 (0.64-0.88)
African-American Sample	0.68 (0.54-0.78)	0.83 (0.49-0.95)

Correlation of NHS II PAQ verses average responses on 28 days of activity diaries

	crude	deattenuated
Representative Sample
Activity 1	0.57 (0.46-0.67)	0.62 (0.44-0.75)
Activity 2	0.46 (0.32-0.58)	0.56 (0.36-0.71)
African-American Sample
Activity 1	0.47 (0.32-0.63)	0.59 (0.31-0.78)
Activity 2	0.54 (0.37-0.68)	0.63 (0.36-0.80)

Activity 1 = the sum of all moderate and vigorous recreational activities with MET values of >4.0
Activity 2 = the sum of all moderate and vigorous activities corresponding to those listed on the NHS II PAQ
