Extended data (supplementary materials) to the manuscript of the research paper entitled `Development and modelling study of an evidence-based manualised intervention: PErsonalised Treatment packages for Adults with Learning disabilities who display aggressive challenging behaviour in community settings (PETAL)`.

The PETAL therapy was designed following an extensive review of existing management provisions and was co-produced with carers with lived experience and self-advocates with an intellectual disability. A single arm multi-site modelling study was conducted in England to test the delivery and acceptability of the PETAL therapy as well as some qualitative interviews with stakeholders to explore the intervention’s fidelity and acceptability.

The extended data (supplementary materials) is in a Word document format and contains three tables (i.e., Summary of intervention development through co-production meetings, PETAL intervention modules and how they map onto the Theoretical Domains Framework (TDF) domains, Implementation strategies following Normalisation Process Theory (NPT).

The TIDieR (Template for Intervention Description and Replication) Checklist is recommended to be complementing reports on new interventions.
