The aim of the present review was to determine whether attentional bias variability (ABV) is causally implicated in emotional vulnerability. We consider evidence examining whether ABV precedes and predicts later psychopathology, and whether modifying ABV leads to changes in psychological symptoms following an intervention.
A systematic literature search located 15 studies that met the inclusion criteria (3 longitudinal, 12 intervention). Eligible intervention studies were also meta-analysed.
Preliminary evidence suggests that ABV predicts later post-traumatic stress symptomatology in interaction with number of traumatic events. The few interventions designed to reduce ABV suggest promise for improving PTSD symptoms. However, these interventions did not consistently change ABV, and where it was tested, change in ABV did not correspond to change in symptoms.
There is emerging evidence that ABV could represent a vulnerability factor for psychological symptoms, particularly for those exposed to trauma. This may indicate attentional control difficulties, although this remains to be tested. Conclusions regarding the causal status of ABV will depend on future high-quality randomised controlled trials.
本综述的目的是确定注意力偏差变异性（ABV）是否与情绪易感性存在因果关系。我们考察了相关证据，以探究ABV是否先于并预测随后的精神病理学状况，以及改变ABV是否会在干预后导致心理症状的变化。
通过系统的文献检索，找到了15项符合纳入标准的研究（3项纵向研究，12项干预研究）。对符合条件的干预研究也进行了荟萃分析。
初步证据表明，ABV与创伤事件数量相互作用时，可预测随后的创伤后应激症状。少数旨在降低ABV的干预措施显示出改善创伤后应激障碍（PTSD）症状的前景。然而，这些干预措施并未持续改变ABV，并且在对ABV进行测试时，ABV的变化与症状变化并不对应。
越来越多的证据表明，ABV可能是心理症状的一个易感性因素，尤其是对于那些遭受创伤的人。这可能表明存在注意力控制困难，尽管这仍有待检验。关于ABV因果关系的结论将取决于未来高质量的随机对照试验。
