Correlation coefficient between attention deficit, hyperactivity impulse and CPT, arithmetic, coding, digit span (r)

SNAP-IV	CPT DEPRIME	Arithmetic	Coding	Digit span
Attention deficit	−0.37*	−0.49**	−0.40*	−0.36*
Hyperactivity impulse	−0.61**	−0.66**	−0.58**	−0.45**

Notes:

^*P<0.05,

^**P<0.01. Pearson correlation analysis was used.

Abbreviation: CPT, continuous performance test.
