Consequently, practitioners have limited amount of data to make informed decisions on whether an intervention may be more suitable than another to begin treating vocal stereotypy. The purpose of the study was to address this limitation by examining the direct and collateral effects of multiple interventions in 12 individuals with autism and other developmental disabilities in order to guide the development of a sequential intervention model. Using single-case experimental designs, we conducted a series of four experiments which showed that (a) noncontingent music generally produced more desirable outcomes than differential reinforcement of alternative behavior, (b) differential reinforcement of other behavior reduced vocal stereotypy in two participants for whom noncontingent music had failed to do so, (c) the addition of simple prompting procedures may enhance the effects of the interventions, and (d) the effects of noncontingent music may persist during sessions with extended durations. Based on these results, we propose a sequential intervention model to facilitate the initial and subsequent selection of an intervention most likely to reduce vocal stereotypy while producing desired collateral outcomes.

False positives with visual analysis for nonconcurrent multiple baseline designs and ABAB designs: Preliminary findings / Marissa A. NOVOTNY in Research in Autism Spectrum Disorders, 8-8 (August 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-8 (August 2014) . - p.933-943 Titre : False positives with visual analysis for nonconcurrent multiple baseline designs and ABAB designs: Preliminary findings Type de document : Texte imprimé et/ou numérique Auteurs : Marissa A. NOVOTNY, Auteur ; Katheryne J. SHARP, Auteur ; John T. RAPP, Auteur ; Joel D. JELINSKI, Auteur ; Elizabeth A. LOOD, Auteur ; Ayriel K. STEFFES, Auteur ; Monica MA, Auteur Article en page(s) : p.933-943 Langues : Anglais (eng) Mots-clés : AB designs  ABAB designs  False positives  Nonconcurrent multiple baseline designs  Reversal designs  Single-subject designs Index. décimale : PER Périodiques Résumé : Abstract This study evaluated the probability of generating false positives with three-tier nonconcurrent multiple baseline (NMBL) designs and ABAB designs. For Experiment 1, we generated four sets of three-tier NMBL design graphs. The first, second, and third sets consisted of fixed A-phase data points for all three tiers at 0%, 25% and 50%, respectively, and randomly generated data points in the B phases. The fourth set consisted of randomly generated data points in the A and B phases for all three tiers. Across all four sets (N = 1000), results show that false positives were produced with 7.5% of three-tier NMBL design graphs and were most probable when baseline levels were set at 0% or 25%. For Experiment 2, we generated 3000 ABAB design graphs consisting of three to five data points per phase. Results indicate that no false positives were produced, regardless of the number of data points included in each phase. Results of this study support specific guidelines for the use of NMBL designs and ABAB designs.
