The effects of progressive relaxation training on the disruptive behavior of a boy with autism.
This study examined the effects of progressive relaxation training on the disruptive behaviors of a boy with autism. Moreover, his overt relaxed behaviors before and after relaxation training were measured using the Behavioral Relaxation Scale (Poppen, 1988, Poppen, 1998). After the participant received training in progressive relaxation procedures a multielement design with three conditions was utilized to determine the effects of the procedures on the duration of the boy's disruptive behaviors during leisure activity sessions. The conditions were: (a) relaxation prior to a leisure activity session; (b) cued relaxation; and (c) no relaxation prior to the session, which represented a baseline condition. Results indicated that the participant acquired progressive relaxation skills, displayed more relaxed behaviors after performing the procedures, and showed a decrease in the duration of his disruptive behaviors upon completing progressive relaxation training prior to a leisure activity session. Implications for future research are discussed.

Reporting of medication regimen in applied studies of persons with mental retardation and ADHD.
The present survey determined whether articles describing attempts to alter behavior in people with mental retardation and Attention-Deficit/Hyperactivity Disorder (ADHD) (a) reported whether or not participants were receiving medications, (b) evaluated drugs as independent variables, and (c) evaluated (or discussed) interactions between pharmacological and nonpharmacological treatments. All behavior-change articles published from 1991 through 1995 in 10 major journals were evaluated. In contrast to the results of earlier surveys, nearly 40% of studies involving participants with mental retardation provided information about medication. This change appears to represent a significant methodological improvement. Nearly 60% of articles involving persons with ADHD provided information about medication. Studies of drugs were common when participants were people with ADHD, but not when they were people with mental retardation. The psychopharmacology of mental retardation continues to be a small, but important, research area. Studies examining treatment interactions were rare, regardless of participants' characteristics. Given that pharmacological treatments may alter participants' sensitivity to nonpharmacological interventions, further research in this area is sorely needed.
