Do delay aversion and executive function deficits make distinct contributions to the functional impact of ADHD symptoms?
The findings of the present study are of importance for current models of heterogeneity in ADHD as they 1) provide further support for the notion that EF deficits and delay aversion are two possible pathways to ADHD, 2) add new interesting knowledge by showing that EF deficits and delay aversion can be differentiated in terms of their relations to the two ADHD symptom domains, and 3) indicate that the two processes of the dual-pathway model can also be differentiated in terms of their effect on functional impairments associated with ADHD.
The SRI-50 is a valid responder index derived form SLEDAI-2K and is very helpful in identifying clinically important improvement in active laboratory descriptors in an efficient time.
