Recent global popularity of social media content about dissociative identity disorder (DID) has coincided with increased self-diagnosis among children and young people who have formed large online communities and presented in clinical settings seeking to affirm their self-diagnoses. We situate this phenomenon within a broader trend toward self-diagnosis due to the widespread visibility and accessibility of mental health content on social media. Social media propelled self-diagnosis raises particular questions for the study and treatment of DID due to long-standing debates over whether the condition is traumagenic, sociogenic, or iatrogenic. This paper draws from the current state of knowledge about psychiatric self-diagnosis, the influence of social media on youth mental health, and the authors’ clinical experience to present preliminary conceptualizations of DID self-diagnosis and its significance for clinical practice. Established etiological models for DID acknowledge the role of sociocultural and contextual factors in shaping and reinforcing the elaboration of DID self-states. We hypothesize that multiple forms of online sociality and interaction encourage such elaborations. Social media content regarding DID, however, is routinely unreliable and low quality, often mischaracterizing the condition’s symptoms and minimizing associated suffering and disability. This paper considers the likelihood that the self-diagnosing DID cohort includes genuine, genuine but exaggerated, imitative, and malingering cases, and underscores the importance of careful and personalized assessment and diagnosis.
