Effect of Therapeutic Intervention Through Art on Catatonic Like Symptoms of Autism Spectrum Disorder

Abstract

This study examined the predictors of catatonia outcomes, focusing on the roles of training, age, and severity level of person with autism. Findings revealed that training and severity level are the strongest predictors, with severity level of Autism Spectrum Disorder (mild, moderate, severe) emerging as a major determinant of both baseline and post-intervention catatonia scores. Higher severity consistently corresponded with elevated symptom levels. While age alone did not significantly influence catatonia, its interaction with severity level produced meaningful variation. Training interventions demonstrated a robust positive effect, underscoring their clinical significance in reducing catatonic symptoms. Post-intervention outcomes were consistent across age groups, suggesting that treatment strategies should be primarily tailored to clinical severity rather than age. The model showed excellent fit (R² ≈ 0.95), accounting for nearly all variance in catatonia outcomes. Descriptive analyses further highlighted substantial individual variability, emphasizing the need for additional correlational and paired-sample studies to refine understanding of treatment responsiveness of children and Perason with Autism Spectrum Disorder.
