Validation Studies of the Perceived Functional Ability (PFA) Questionnaire/ Physical Activity Rating (PA-R) Questionnaire

George et al. 1996

See reference #50

Methods
Relation between Perceived Functional Ability (PFA) questions and Physical Activity rating (PA-R) questions, to non-exercise (N-Ex) VO2 max estimations. Multiple regression coefficients
Sample
50 male and 50 female college students; 22.3 ± 3.0 years of age
Summary Results
N-Ex VO2 max regression equations:
  MODEL 1 MODEL 2
  B B-weight B B-weight
PFA 0.738** 0.46** 0.724** 0.45**
PA-R 0.688* 0.17* 0.788* 0.20*

* p < 0.001   ** p < 0.0001

Summary Legend:
Model 1: Self-report predictor variables
Model 2: Self-report and measured (BMI) predictor variables
B = multiple regression coefficients
B-weight = standardized multiple regression coefficients
PFA = Perceived Functional Ability
PA-R = Physical Activity rating
N-Ex = Non-exercise VO2
