After gathering important information during the assessment process, clinicians can begin working with their patients to collaboratively develop a conceptualization of the patient’s disorder. This early phase of treatment provides an opportunity for clinicians to educate patients about their disorders, including the complex nature of comorbid OCD and EDs, and obtain informed consent for treatment. Informed consent is essential as it ensures that patients understand the treatment options, their potential risks and benefits, and the uncertainty surrounding the best course of treatment for this comorbidity. A functional analysis, which assesses the purpose and function of the patient’s behaviors, can provide valuable data for creating a treatment plan. By understanding the root and function of the patient’s behaviors, it will be possible to prioritize treatment and develop a promising treatment plan. Additionally, it is crucial for clinicians to assess the impact of malnutrition or weight loss on the patient, as this will inform treatment planning and may affect the course of treatment.
