Stability and convergent validity of the Physical Activity Scale for the Elderly (PASE).
OBJECTIVE
The purpose of this study was to assess the stability and convergent validity of the Physical Activity Scale for the Elderly (PASE) among rural, community dwelling elderly persons using Computer Science and Applications, Inc. Actigraph Monitors (Actigraph) as the direct criterion measure.


METHODS



METHODS
a correlational design was employed.


METHODS
rural community in the United States.


METHODS
56 subjects (age=75.7+/-7.9 years) who were living independently and volunteered to participate in the study.


METHODS
subjects wore an Actigraph monitor during all waking hours for 7 consecutive days. At the conclusion of the 7 days, each subject met with a trained interviewer to complete the PASE questionnaire. Three days later the subjects met with the same interviewer to complete the PASE a 2nd time recalling their physical activity for the same 7-day period.


RESULTS
Actigraph data indicated that subjects averaged 168.1+/-76.3 counts x minute(-1) during the 7-day period. A high intraclass correlation coefficient (r=0.91) was calculated between the 1st interview total PASE score (115.97+/-59.91) and the 2nd interview total PASE score (115.71+/-50.97). In addition, there was a statistically significant Spearman correlation coefficient of 0.43 (p<0.01) between Actigraph mean counts x minute(-1) and 1st interview total PASE scores.


CONCLUSIONS
In this rural elderly sample, the PASE was a stable instrument with validity indices similar to those previously reported in younger, more active, populations.
