Thompson‐Hollands et al.’s (2020) commentary on our systematic review of exposure‐based writing therapies for subthreshold and clinical posttraumatic stress symptoms (Dawson et al., 2020) emphasizes important questions about the impact of heterogeneity in drawing inferences from evidence reviews. In this reply, we discuss (a) our rationale for undertaking a systematic review that was broad rather than narrow in scope and (b) provide clarifications on how heterogeneity was considered in the meta‐analyses that were conducted. We also strongly agree with Thompson‐Hollands et al.’s recommendation that future research should focus on better understanding the mechanisms by which exposure‐based writing therapies help reduce posttraumatic stress symptoms.

关于阈下和临床创伤后应激障碍的基于暴露的写作疗法的新兴文献：对 Thompson-Hollands 等人（2020）对 Dawson 等人的评论的回应。(2020)

Thompson-Hollands 等人（2020 年）对我们针对阈下和临床创伤后应激症状的基于暴露的写作疗法的系统评价（Dawson 等人，2020 年）的评论强调了关于异质性在从证据中得出推论的影响的重要问题评论。在本答复中，我们讨论了 (a) 我们进行范围广泛而不是狭窄的系统评价的理由，以及 (b) 阐明了在进行的荟萃分析中如何考虑异质性。我们也非常同意 Thompson-Hollands 等人的建议，即未来的研究应侧重于更好地了解基于暴露的写作疗法有助于减轻创伤后压力症状的机制。
