Self-monitoring is a core component of cognitive behavioral therapy (CBT) and is often used in the treatment of eating disorders (EDs) and obsessive-compulsive disorder (OCD). It enables individuals to observe their behaviors and thought patterns, identify triggers and areas of strength, and make changes to improve their mental and physical health. For individuals with co-occurring OCD and EDs, self-monitoring can be especially useful in discerning between their thoughts and those influenced by their pathology. However, there is a risk that self-monitoring can become compulsive and part of the OCD. In people with OCD, the process of information gathering can fuel the disorder and lead to prolonged distress, rigidity, and a lack of mindfulness. To address this, a therapist may suggest modifying the self-monitoring protocol or incorporating OCD-specific treatment such as exposure and response prevention (ERP) into the treatment plan. It’s important for individuals to seek professional help and support to address their co-occurring OCD and ED. Clinicians treating EDs should be aware of the signs that OCD may be impacting the self-monitoring process and take steps to address it.
