Use of single-subject methodology in clinical decision-making with a hyperactive child on the psychiatric inpatient unit
The efficacy of various types of stimulant medications as well as behavioral interventions for treatment of hyperactive children has been well established. The present study illustrates the use of single-subject methodology in deciding which treatment or combination of treatments is most appropriate for any given individual. Using an A B A C CD A1D CD design, the relative clinical effectiveness of dextroamphetamine (Dexedrine) (B), methylphenidate (Ritalin) (C), behavioral self-control (D), and their combination was assessed in a hyperactive child. Assessment occurred across two response systems, behavioral and physiological. A combination of methylphenidate plus behavioral self-control procedures produced the most efficacious outcome. Results are discussed in terms of the usefulness of single-subject methodology in guiding the clinical decision-making process for an individual client. © 1981.
