This guide shows how clinicians can help girls and young women with ASC to reach their full potential, by adopting more relationship-based, individualised approaches. With contributions from young women about their experiences in clinical settings, the book reflects on what clinicians have done right and wrong to date, why girls and women with ASC are too often misunderstood, and how the culture of how clinicians work with them needs to change in order to achieve better results. In a concise and practical way, it covers how to better understand clients' needs and foster strong relationships through diagnosis, understanding comorbidities, sensory issues, self-harm, emotional regulation, assessments, interventions and strategies.
