There is no significant difference in the amount of trauma those with OCD, hoarding disorder, or a combination of both experienced before they developed their symptoms. However, it is essential to note that the severity of hoarding was impacted by the amount of past traumatic experiences.

Traumatic Events Before OCD or Hoarding Symptom Development

Przeworski, A., Cain, N., & Dunbeck, K. (2014). Traumatic life events in individuals with hoarding symptoms, obsessive-compulsive symptoms, and comorbid obsessive-compulsive and hoarding symptoms. Journal of Obsessive-Compulsive and Related Disorders, 3(1), 52–59. https://doi.org/10.1016/j.jocrd.2013.12.002

References for the Link Between Traumatic Events and OCD/Hoarding Symptoms

The link between the types of past traumatic events and OCD and hoarding symptoms.

The more traumatic events one experiences, the higher severity of hoarding symptoms people may develop. This is not the same for OCD. This unique finding should be considered in therapy settings when addressing hoarding behavior.
