Table 5 Concurrent and Predictive Validity Tests for SEPA Scale With Collapsed Response Options

From: Psychometrics of the self-efficacy for physical activity scale among a Latina women sample

  SEPA at 6 months SEPA at 12 months
7-day PAR at 6 months (minutes/week) ρ = 0.459** n/a
Accelerometer 6 months (minutes/week) ρ = 0.295** n/a
7-day PAR 6 months (meeting guidelines) t(43) = −5.945** n/a
Accelerometer 6 months (meeting guidelines) t(18) = −2.979** n/a
7-day PAR at 12 months (minutes/week)a B = 0.643** SE = 0.186 ρ = 0.429**
Accelerometer 12 months (minutes/week)a B = 0.534** SE = 0.174 ρ = 0.331**
7-day PAR 12 months (meeting guidelines) B = 0.229** SE = 0.083 t(71) = −4.227**
Accelerometer 12 months (meeting guidelines) B = 0.174+ SE = 0.103 t(30) = − 2.703*
  1. **p value < .01, *p value < .05, +p value < .1
  2. Note a: In linear regression models, square root transformations were used for the outcome variables (7-day PAR and accelerometer-measured MVPA)
