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.

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.

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).

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.

童年创伤对强迫症状严重程度的影响:系统评价

背景

童年创伤与一系列精神疾病有关,包括强迫症 (OCD)。然而,我们对不同类型的童年创伤及其对强迫症 (OCS) 不同类型和严重程度的影响的理解仍处于起步阶段。

宗旨

我们进行了系统评价,以综合目前关于临床和非临床人群中儿童创伤与强迫症状之间可能关系的知识。

方法

我们系统地搜索了四个电子数据库,以获取有关儿童创伤和 OCS 严重程度的研究报告。随后,我们定性地综合了合格研究的结果,并计算了效应量。

结果

本系统评价纳入了 24 项研究。大多数研究使用强迫 症样本 ( k = 16),少数研究使用包含一系列精神疾病的样本 ( k  = 6),一些研究使用一般社区样本 ( k  = 2)。总体而言,支持童年创伤与 OCS 严重程度之间存在显着关系(16 项研究中的 8 项使用 OCD 临床样本,两项研究均使用一般人群样本,6 项研究中的 5 项使用混合精神病样本)。

结论

我们发现了临床和非临床人群中儿童期创伤暴露与 OCS 严重程度之间存在显着关系的证据。我们的结果还表明,一系列而非单一类型的童年创伤与强迫症有关。
