A single case ABA experimental design is presented in which techniques to facilitate mouth closure were hypothesized to decrease drooling. The subject was an 11-year-old male with mental retardation and cerebral palsy. Baseline 1 consisted of 10 half-hour sessions of play, followed by 1-hour periods during which the amount of saliva collected on an absorbent bib was measured and recorded. The subsequent treatment phase of 4 weeks was identical to the baseline except that a half-hour period of intervention was substituted for the half-hour of play. Intervention involved providing jaw control with intermittent tapping and jiggling, stroking the upper gum, and giving juice with jaw control. Baseline 2 consisted of 10 sessions identical to baseline 1. Results indicate that the amount of saliva leaving the mouth was a function of the presence or absence of intervention.

As part of an ongoing, prospective, ABA design, double-blind crossover study of risperidone versus placebo for the treatment of aggressive, destructive and self-injurious behavior in persons aged 6-65 years with mental retardation (MR) and autism, we measured the weight of 19 subjects at each study visit. We compared mean weight gain during the 16-week acute phase and 24-week open maintenance phase with that during the initial and middle placebo phases statistically, using a linear mixed model procedure. Results of the linear mixed model analysis showed that relative weight gain observed during the acute and maintenance drug phases was significantly greater than that observed during the initial and middle placebo phases respectively (p = .0001 and p = .0001). Over approximately a year, children aged 8-12 (n = 5) gained a mean of 8.2 kg (range = 2.7-17.7 kg); adolescents (n = 6) aged 13-16 gained a mean of 8.4 kg (range 3.6-15.5 kg); adults aged 21-51 (n = 8) gained a mean of 5.4 kg (range 0-9.5 kg). Weight gain observed in this controlled study of risperidone treatment in children, adolescents, and adults with MR and autism was significant. It may be greater in this population than in others reported and in this study was not limited to an acute effect only. Rate of weight gain diminished rapidly on tapering and stopping the drug. Further studies are urgently needed, including those incorporating diet and exercise programming.

This article updates previous content analyses of the Journal of Music Therapy (JMT) and presents information regarding the behavioral research approach to music therapy as reflected by published studies. JMT articles from 1964 through 1999 were examined to determine if the methodology included a behavioral research design (e.g., reversal, multiple baseline). Case studies not meeting the design criteria were excluded from the sample as were experimental group studies using a behavioral observation method or behavioral technique within a traditional statistical design. Experimental studies, however, in which behavioral research designs were included in treatment conditions and assigned to different groups were included. Articles meeting the behavioral research design criteria were analyzed to determine the type of design, the behavioral observation method and reliability report, the client population, and the music application. Of the 607 articles published in JMT, 96 or 15.8% included a behavioral research design. The lowest percentage occurred in the earliest volumes of JMT during the latter part of the 60s. An increase in behavioral research articles occurred during the 70s and 80s and continued throughout the 90s. Other findings include the following: (a) the most prevalent design was the reversal (ABA) with many variations; (b) the predominant observation methods were frequency counts and interval recording with an increase in observation reliability reports in the 80s and 90s; (c) studies published during the 80s and 90s included a wide variety of client populations compared to the 60s and 70s predominant applications with mental retardation and emotional disturbances; (d) the contingent application of music was highest during the 70s and 80s and virtually nonexistent during the 60s and 90s when other treatment conditions employed music as noncontingent background stimulus, an activity for structuring responses, and a cue for maintaining nonmusic responses. The increase in articles through the decades coupled with the increased diversity of populations suggests that behavioral research designs are flexible and applicable in music therapy practice today as much as they were during the initial phase during the 70s and 80s.
