Focused ABA refers to treatment provided directly to the client for a limited number of behavioral targets. It is not restricted by age, cognitive level, or co-occurring conditions. Focused ABA generally ranges from 8-25 hours per week of direct treatment (plus direct and indirect supervision and caregiver training). However, certain programs for severe destructive behavior may require more than 25 hours per week of direct therapy (for example, day treatment or inpatient program for severe self-injurious behavior). Even when reduction of problem behavior is the primary goal, it is critical to also target increases in appropriate alternative behavior, because the absence of appropriate behavior is often the precursor to serious behavior disorders. Therefore, individuals who need to acquire skills (for example, communication, tolerating change in environments and activities, self-help, and social skills) are also appropriate for Focused ABA.
