title: The Test of Variables of Attention (TOVA): internal consistency (Q₁ vs. Q₂ and Q₃ vs. Q₄) in children with attention deficit/hyperactivity disorder (ADHD).
abstract: The internal consistency of the Test of Variables of Attention (TOVA) was examined in a cohort of 6- to 12-year-old children (N = 63) strictly diagnosed with ADHD. The internal consistency of errors of omission (OMM), errors of commission (COM), response time (RT), and response time variability (RTV) of different test conditions (stimulus infrequent condition [Q₁ vs. Q₂] and stimulus frequent condition [Q₃ vs. Q₄]) was assessed via correlation analyses. All TOVA index scores under investigation assessing its internal consistency exhibited statistically significant correlations. All correlations fell in the moderate-high range.
