Dr Amita Jassi

Consultant Clinical Psychologist

Area of expertise
Research interests include OCD, BDD and related disorders; phenomenology, factors affecting treatment outcomes, developing and improving treatments for these conditions, impact of ethnicity on access and treatment, family accommodation, ASD, multi-family group.

Dr Amita Jassi is a Consultant Clinical Psychologist at the National and Specialist OCD, BDD and Related Disorder Service for Children and Young People (South London and Maudsley NHS Trust). She has worked with this client group since 2006. Amita is the lead for the BDD branch of the service as well as the research lead for the clinic.

In her clinical role, she leads multi-disciplinary specialist assessments and develops and delivers individually-tailored treatment packages, including intensive, home-based and inpatient treatment, as well as offering consultation and joint work with clinicians around the country. Amita has taught and trained nationally and internationally on child and adolescent OCD and BDD and engages with media to help increase awareness and understanding of OCD, BDD and related disorders.

Following the completion of her training in Clinical Psychology in 2006, Dr Jassi worked in socially deprived areas in West London setting up Psychology services in pre-school children in Children Centres. Following this, in 2008 she returned to South London and Maudsley NHS Trust to work on the first randomised controlled trial to examine the effectiveness of Cognitive Behaviour Therapy (CBT) for Obsessive Compulsive Disorder (OCD) in people with Autism. This fused her passion of working with OCD whilst undertaking high quality clinical research.

This fusion has continued when she joined the National Specialist OCD, BDD and related disorders team in 2010, where she worked on further trials as well as contributing to the clinical service. Her career has continued within the team where she is now a Consultant Clinical Psychologist leading the pioneering BDD branch of the service. She is also the research lead for the service, supporting the team to continue to contribute to the evidence-base with clinically informed high quality research in OCD, BDD and related disorders.
