注意偏差可能是酒精依赖和社交焦虑的重要治疗目标。这是第一个 ABM 试验，旨在调查样本中两个（相对于一个）注意力偏差目标，同时出现社交焦虑和酒精依赖症状。此外，与传统的注意力偏差分数相比，我们使用试验级偏差分数（TL-BS）以更生态有效、动态的方式捕捉注意力偏差现象。具有较高社交焦虑症状和酒精依赖的成年参与者（N = 86；41% 女性；52% 非裔美国人；40% 白人）被随机分配到 2（社交焦虑 ABM 与社交焦虑控制）by 2（酒精 ABM 与酒精控制）设计中的 8 节训练条件。随着时间的推移，对社交焦虑、酒精依赖和注意力偏差的症状进行了评估。多级模型估计个体内每项测量的轨迹，并测试这些轨迹是否根据随机训练条件而有所不同。随着时间的推移，所有注意力 TL-BS 参数（但不是传统的注意力偏差分数）和大多数症状测量值均出现显着或趋势性下降。然而，对于任何症状测量，任何 ABM 和控制条件之间的变化轨迹没有显着差异。这些发现补充了之前质疑 ABM 稳健性的证据，并指出需要将 ABM 的影响扩展到种族多样化和/或同时发生精神病理学的样本。结果还说明了计算试验级注意力偏差分数而不是仅包括传统偏差分数的潜在重要性。
Attention biases may be an important treatment target for both alcohol dependence and social anxiety. This is the first ABM trial to investigate two (vs. one) targets of attention bias within a sample with co-occurring symptoms of social anxiety and alcohol dependence. Additionally, we used trial-level bias scores (TL-BS) to capture the phenomena of attention bias in a more ecologically valid, dynamic way compared to traditional attention bias scores. Adult participants (N=86; 41% Female; 52% African American; 40% White) with elevated social anxiety symptoms and alcohol dependence were randomly assigned to an 8-session training condition in this 2 (Social Anxiety ABM vs. Social Anxiety Control) by 2 (Alcohol ABM vs. Alcohol Control) design. Symptoms of social anxiety, alcohol dependence, and attention bias were assessed across time. Multilevel models estimated the trajectories for each measure within individuals, and tested whether these trajectories differed according to the randomized training conditions. Across time, there were significant or trending decreases in all attention TL-BS parameters (but not traditional attention bias scores) and most symptom measures. However, there were not significant differences in the trajectories of change between any ABM and control conditions for any symptom measures. These findings add to previous evidence questioning the robustness of ABM and point to the need to extend the effects of ABM to samples that are racially diverse and/or have co-occurring psychopathology. The results also illustrate the potential importance of calculating trial-level attention bias scores rather than only including traditional bias scores.
