People tend to live with obsessive-compulsive disorder (OCD) for many years before receiving evidence-based treatment. This delay is partly due to a lack of access to information about which healthcare providers offer evidence-based treatment for OCD. This information was not easily accessible online for people in Australia. In this study, we describe how an online directory of clinicians was developed and evaluated. We report on a needs analysis and survey of treatment-seeking histories among consumers and carers impacted by OCD. We describe the key features of the directory developed, and present survey feedback on its usability and utility. The results validated the need for a directory specific to clinicians who offer evidence-based treatment for OCD, and that it meets essential usability standards. Areas for improvement and further developments were identified. This directory contributes to broader efforts invested to improve the treatment-seeking process for people living with OCD in Australia. What is already known about this topic: Globally, barriers to access delay appropriate treatment for OCD. One barrier is not knowing who offers evidence-based treatment specific to OCD. In Australia, there is no central source that provides such information. What this topic adds: The delays in treatment reported in Australia are comparable to other countries. We developed a directory of clinicians with a special interest in treating OCD. Consumer feedback suggests the directory will assist the treatment-seeking process. [ABSTRACT FROM AUTHOR]
