Note: Additional analyses utilizing log, inverse, and square root transformations produced consistent results that did not differ regarding the significance of any individual predictors, model steps, or Δ R2. The range of Δ R2 using the transformed data was 0.19 to 0.20. ** p < 0.01; *** p < 0.001.
