	R2=0.06 for step 1; ΔR2=0.10 for step 2, ns				R2=0.05 for step 1; ΔR2=0.08 for step 2, ns

Notes: b= unstandardized regression coefficient; β= standardized regression coefficient; P= significance value; R²= total variance explained by the model; ΔR²= variance explained by CTQ subscales after adjusting for age, body mass index, and menstrual cycle phase.
