DSLM Study
Lim (PI) performed randomized control trials with DSLM (Lim, 2010) on children 3-5 years of age with ASD (n=50), divided into low-functioning (n=25) and high-functioning (n=25) groups based on their scores on either the Childhood Autism Rating Scale (CARS) (Schopler et. al, 1988), or the Autism Diagnostic Interview Revised (ADI-R) (Lord et. al., 1994).

The study measured performance with the author’s Verbal Production Evaluation Scale (VPES) that measures four aspects of speech and language: prosody, pragmatics, articulation and phonology.

Three conditions were tested in between-subject groups:
music-based training, speech-only training, and no training.

High-functioning children with minor speech deficits responded equally to music-based and non-music-based training. More significantly, the low-functioning
children with severe speech-delays responded to DSLM music-based training with 60% improvement in their VPES scores, while the control group using non-music-based training exhibited 15% improvement.

The results of this analysis indicate that an interaction between training condition and level of functioning may in fact exist in the population, since the statistical results of this interaction approached significance.
