The most common side effects was poor appetite. There were no association between ADHD symptoms evaluated by the SNAP-IV-P and medication non-adherence (r = .175, p-value = .170). Non-adherence subjects were statistically significant more treated with methylphenidate than extended-release methylphenidate. (t = -2.21, p = 0.03, ᵡ2 = 7.96, p = 0.005)
