Title : Reduction in the severity of ASD with the Katia Dolle Method : A retrospective cross-sectional study
Abstract:
Materials and Methods: Data were collected from an online program conducted between 2017 and 2024. A total of 183 children aged 1–13 years from 26 countries participated. Ninety-eight cases were excluded due to lack of adherence or missing data. Parent-reported ATEC (Autism Treatment Evaluation Checklist) scores at baseline and at the end of the intervention were compared. Higher scores indicate greater severity. Statistical analyses included paired Student’s t-test, ANOVA, and multivariable regression. Significance testing, normality checks, and confidence intervals were applied.
Results: The mean reduction in total ATEC was 39.20 points (95% CI: 36.20–42.20) over 13.9 months, a highly significant difference (p < 0.001). Relative reductions for each subscale were calculated based on each subscale’s scoring range. The largest reduction was observed in Sensory/Cognitive Awareness (28.23%), followed by Language and Communication (27.01%), Sociability (22.38%), and Health and Behavior (16.69%).
Conclusions: In this analysis, the Katia Dolle Method®, grounded in naturopathic science, is associated with clinically relevant reductions in total ATEC and subscales, particularly among participants who were more severe, younger, and had longer intervention duration. The main limitations are the absence of a control group and parent completion of the ATEC. Prospective controlled studies are needed to confirm these findings.
