We respond to Lynn et al.'s (2014) comments on our review (Dalenberg et al., 2012) demonstrating the superiority of the trauma model (TM) over the fantasy model (FM) in explaining the trauma-dissociation relationship. Lynn et al. conceded that our meta-analytic results support the TM hypothesis that trauma exposure is a causal risk factor for the development of dissociation. Although Lynn et al. suggested that our meta-analyses were selective, we respond that each omitted study failed to meet inclusion criteria; our meta-analyses thus reflect a balanced view of the predominant trauma-dissociation findings. In contrast, Lynn et al. were hypercritical of studies that supported the TM while ignoring methodological problems in studies presented as supportive of the FM. We clarify Lynn et al.'s misunderstandings of the TM and demonstrate consistent superiority in prediction of time course of dissociative symptoms, response to psychotherapy of dissociative patients, and pattern of relationships of trauma to dissociation. We defend our decision not to include studies using the Dissociative Experiences Scale-Comparison, a rarely used revision of the Dissociative Experiences Scale that shares less than 10% of the variance with the original scale. We highlight several areas of agreement: (a) Trauma plays a complex role in dissociation, involving indirect and direct paths; (b) dissociation-suggestibility relationships are small; and (c) controls and measurement issues should be addressed in future suggestibility and dissociation research. Considering the lack of evidence that dissociative individuals simply fantasize trauma, future researchers should examine more complex models of trauma and valid measures of dissociation.
我们对 Lynn 等人(2014)对我们的评论(Dalenberg 等人,2012)的回应,该评论表明创伤模型(TM)在解释创伤-分离关系方面优于幻想模型(FM)。Lynn 等人承认,我们的荟萃分析结果支持 TM 假设,即创伤暴露是分离发展的因果风险因素。尽管 Lynn 等人认为我们的荟萃分析具有选择性,但我们回应说,每个被排除的研究都不符合纳入标准;因此,我们的荟萃分析反映了对主要创伤-分离发现的平衡看法。相比之下,Lynn 等人对支持 TM 的研究过于苛刻,而忽略了支持 FM 的研究中存在的方法学问题。我们澄清了 Lynn 等人对 TM 的误解,并证明了 TM 在预测分离症状的时间进程、对分离患者的心理治疗反应以及创伤与分离关系的模式方面具有一致的优越性。我们为不包括使用分离体验量表比较(Dissociative Experiences Scale-Comparison)的研究做出了解释,这是分离体验量表的一个很少使用的修订版,与原始量表的差异不到 10%。我们强调了几个达成共识的领域:(a)创伤在分离中起着复杂的作用,涉及间接和直接路径;(b)分离-暗示性关系较小;(c)未来的暗示和分离研究应解决对照和测量问题。考虑到没有证据表明分离个体只是幻想创伤,未来的研究人员应该研究更复杂的创伤模型和有效的分离测量方法。
