Table 3 Concurrent and Predictive Validity Tests for Original SEPA Scale

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 = 0.464** n/a
Accelerometer 6 months (minutes/week) ρ = 0.273** n/a
7-day PAR 6 months (meeting guidelines) t(40) = −5.605** n/a
Accelerometer 6 months (meeting guidelines) t(18) = − 2.789* n/a
7-day PAR at 12 months (minutes/week)a B = 0.368** SE = 0.109 ρ = 0.492**
Accelerometer 12 months (minutes/week)a B = 0.313** SE = 0.102 ρ = 0.340**
7-day PAR 12 months (meeting guidelines) B = 0.129** SE = 0.472 t(64) = − 5.157**
Accelerometer 12 months (meeting guidelines) B = 0.081 SE = 0.058 t(29) = − 2.565*
  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)
