Construct validity of selected measures of physical activity beliefs and motives in fifth and sixth grade boys and girls.

ABSTRACT:

Objective

Scales used to measure selected social-cognitive beliefs and motives for physical activity were tested among boys and girls.

Methods

Covariance modeling was applied to responses obtained from large multi-ethnic samples of students in the fifth and sixth grades.

Results

Theoretically and statistically sound models were developed, supporting the factorial validity of the scales in all groups. Multi-group longitudinal invariance was confirmed between boys and girls, overweight and normal weight students, and non-Hispanic black and white children. The construct validity of the scales was supported by hypothesized convergent and discriminant relationships within a measurement model that included correlations with physical activity (MET • min/day) measured by an a
