Disorder Research

Advancing equity and access.

Closing the Health Equity Gap

Despite the existence of effective therapies, not all segments of society have been able to access effective care for OCD. Dr. Williams' research into this issue found widespread and ongoing exclusion of racialized groups from specialized treatment facilities and treatment outcome studies. Her research has been focused on improving access for all.

Taboo Symptoms

Dr. Williams has been a leader in raising awareness about frequently misdiagnosed OCD symptoms. She published the first research articles on sexual obsessions in OCD. She developed a new measure (the SORT) to help clinicians distinguish between sexual orientation fears in OCD and a sexual identity crisis in sexual minority individuals. As such, she has been recognized as the leading expert on this topic and was commissioned by Oxford University Press, to complete a treatment manual for sexual worries in OCD, published in 2019, entitled Sexual Obsessions in OCD: Definitive Guide to Understanding, Diagnosis, & Treatment.
