This paper presents a new 16-item scale designed to measure attitudes regarding the importance of role modeling in physical activity and fitness behaviors among Health, Physical Education, Recreation, and Dance professionals. The measure was reviewed for face validity by a panel of experts and preliminary analyses gave as Cronbach alpha of .95 and split-half reliability of .97 for 22 graduate students.
Physical Activity Readiness Questionnaire (PARQ) clearance has been recommended prior to low-to-moderate exercise involvement. The measure, however, appears to exclude a high proportion of older adults due to false positive responses. To improve this situation, a revised PARQ was developed (rPARQ). The purpose of this study was to compare the number exclusions resulting from the PARQ and rPARQ in 60- to 69-yr-old adults. Participants were recruited from Community Nutrition Centers (97 males, 96 females; mean age = 64.82 yr, SD +/- 2.85). At random, half completed the PARQ or rPARQ on day 1 and the respective opposite instrument on day 2. There was a significant decrease in the number of exclusions resulting from the PARQ as compared to the rPARQ (146 to 128, P < 0.001). Percentage of agreement regarding exclusion/inclusion status between the two measures was 87.6% (kappa = 0.71). Responses for the six matched questions were significantly (P < 0.0001) related with contingency and phi coefficients ranging from 0.40 to 0.58 and 0.43 to 0.71, respectively. These results support the concurrent validity of the rPARQ and suggest the revisions have had their intended effect.
Drawing from the Theoretical Pattern of Physical Activity Model of Blair, Kohl, and Gordon, a Lifestyle Exercise Inventory was developed. The internal consistency (.69, n = 178), test-retest reliability (.77), and criterion validity (-.27, .29, .32, and .32) of the measure are reported for 178 women.
