N2  - BACKGROUND: Childhood trauma is associated with a range of psychiatric disorders, including obsessive-compulsive disorder (OCD). However, our understanding of the different types of childhood trauma and its impact on the different types and severity of obsessive-compulsive symptoms (OCS) is still in its infancy. AIMS: We conducted a systematic review to synthesise the current knowledge on the possible relationships between childhood trauma and obsessive-compulsive symptoms in clinical and non-clinical populations. <br><br>METHODS: We systematically searched four electronic databases for studies reporting on childhood trauma and OCS severity. Subsequently, we qualitatively synthesised results of eligible studies and effect sizes were also calculated. <br><br>RESULTS: Twenty-four studies were included in this systematic review. Most studies used OCD samples (k = 16), with a few studies using a sample comprising of a range of psychiatric disorders (k = 6) and some studies using a general community sample (k = 2). Overall, there was support for a significant relationship between childhood trauma and OCS severity (8 out of 16 of the studies using OCD clinical samples, both studies using general population samples, and 5 out of 6 studies used mixed psychiatric samples). <br><br>CONCLUSIONS: We found evidence of a significant relationship between exposure to childhood trauma and OCS severity across clinical and non-clinical populations. Our results also suggest that a range rather than a single type of childhood trauma was associated with OCD.<p />  <p>Language: en</p>
