Contextual Fit of Interventions for Vocal Stereotypy: A Systematic Review of Research Evaluating Antecedent-Based Interventions
摘要
Vocal stereotypy (VS) is characterized by non-contextually appropriate repetitive vocalizations (e.g., words, humming) that often occur in the absence of social contingencies (Rapp & Vollmer, 2005, https://doi.org/10.1016/j.ridd.2004.11.005). Members of the Autistic community have shared how stereotypy should be accepted as a form of self-regulation, acknowledged as part of their Autistic identity, and suggest not to target it for suppression (Kapp et al., 2019, https://doi.org/10.1177/1362361319829628). Alternatively, it has been suggested that treatment should be considered in some cases, such as when stereotypy is interfering with skill acquisition (Leaf et al., 2022, https://doi.org/10.1007/s10803-021-05137-y). Furthermore, antecedent-based interventions appear to closely align with the perspective of the neurodiversity movement. Therefore, this review summarizes previous research on antecedent-based interventions for VS, with the primary aim of evaluating the different indices of contextual fit (i.e., need for treatment, efficacy, efficiency, and cultural relevance). The current literature review includes 195 treatment evaluations across 34 studies published between 1994 and 2023. The antecedent-based intervention evaluated most frequently was environmental enrichment, and some studies included indices of contextual fit. We discuss implications for clinical practice, areas for future research, and the overlap between contextually fit and neurodiversity-affirming interventions.
