4.3. Potential downsides of a name-brand
A name-branded intervention frequently combines a variety of elements that are not assessed separately. Namely, the brand frequently advocates for a “treatment package” preventing separate analyses of specific treatment components. Unlike TEACCH, approaches to treatment based on applied behavior analysis are supported by a large corpus of molecular analyses in the form of single-subject experimental studies. Treatment evaluations of TEACCH focusing on specific treatment components and specific treatment outcomes are sorely needed. Finally, branded interventions tend to centralize services and training, which may harm the scientific integrity of the intervention by limiting the opportunities of widespread dissemination and evaluation.
In summary, the following considerations may be relevant for future research: (a) adherence to the general quality standards of controlled trials including randomization, intention to treat analysis, and treatment fidelity; (b) prioritization of controlled studies as pre–post designs may be subjected to developmental confounders; (c) implementation of standardized assessments developed outside the TEACCH tradition including standardized measures of both intellectual functioning and actual achievement; (d) improvement of the comparability of the intervention and control groups in terms of hours of intervention on occasions when a no-intervention control group is not feasible, and (e) prioritization of studies comparing more than one form of intervention in order to establish the relative advantages and disadvantages of TEACHH.
