This comprehensive, research-informed guide supports Autistic adults navigating the diagnostic process and clinicians seeking to offer affirming assessments. Created by Jacqueline Gibb, an Autistic therapist, it translates DSM-5 criteria into lived experience, offering over 150 real-world examples across social, sensory, and behavioural domains. The resource gently reframes diagnostic language from deficit-based to difference-based, helping users identify traits without pathologising themselves.

Structured around Criteria A and B, it includes reflective prompts to help users document their own experiences across life stages and contexts—essential for adult diagnosis. It also offers practical advice on choosing neurodiversity-affirming clinicians, understanding assessment pathways in Australia, and weighing the risks and benefits of diagnosis.

Whether you're seeking clarity, preparing for assessment, or supporting others, this resource empowers you to approach diagnosis with self-understanding and agency. It’s ideal for late-diagnosed adults, therapists, psychologists, and support workers committed to respectful, inclusive practice.
