Table 4 Clinical outcome data for patients with ADHD in continuing care receiving methylphenidate (random sample; N = 119)

ADHD attention-deficit/hyperactivity disorder, ADHD-RS-IV attention-deficit/hyperactivity disorder rating scale IV, MPH methylphenidate, n/a not available, SD standard deviation
^aCalculated by dividing the total/subscale score by the number of items (9 for each subscale; 18 for the total)
^bPre-treatment (all patients were naïve to ADHD medication)
^cMean scores over all (post-titration) continuing care visits
^dPearson correlation between time in treatment (months) and ADHD-RS-IV subscale and total scores at most recent clinic visit: Inattention, rho = –0.197, p = 0.07; Hyperactivity/Impulsivity: rho = –0.067, p = 0.5; Total score, rho = –0.145, p = 0.1
