Anxiety disorders are globally prevalent, debilitating and onset in early life. Cognitive bias modification of interpretations (CBM-I) training has emerged as a targeted intervention for early emerging anxiety problems. While CBM-I can alter interpretational styles in unselected and clinical-analogue samples of adolescents, no studies have assessed its capacity to change biases in clinical samples. Here, we assessed training efficacy in ameliorating interpretation biases and anxious mood in adolescents with anxiety disorders. Twenty-eight Chinese adolescents meeting criteria for a current anxiety disorder were randomly assigned to receive positive or neutral CBM-I training. Training involved completing a word-fragment to resolve the outcomes of sixty ambiguous scenarios. During positive training, scenarios ended with benign/positive resolutions, but during neutral training, half of the scenarios were resolved positively and half negatively. Positively trained patients interpreted new ambiguous scenarios less negatively than the neutral training group although training effects were not observed on a questionnaire measure of interpretation bias. Training effects on mood were also absent. Before the clinical implications of CBM-I can be considered in adolescents, research needs to establish optimal training parameters for symptom-changes to occur.
焦虑障碍在全球范围内普遍存在,会使人衰弱,并在生命早期发作。认知偏差修正解释(CBM-I)训练已成为针对早期出现的焦虑问题的一种靶向干预措施。虽然 CBM-I 可以改变未选择和临床模拟的青少年样本中的解释风格,但尚无研究评估其改变临床样本中偏差的能力。在这里,我们评估了在改善焦虑障碍青少年的解释偏差和焦虑情绪方面的训练效果。28 名符合当前焦虑障碍标准的中国青少年被随机分配接受积极或中性 CBM-I 训练。训练包括完成单词片段来解决六十个模糊情景的结果。在积极训练中,情景以良性/积极的结果结束,但在中性训练中,一半的情景以积极和消极的方式解决。尽管在解释偏差的问卷测量上没有观察到训练效果,但接受积极训练的患者对新的模糊情景的解释不如中性训练组那么消极。对情绪的训练效果也不存在。在考虑将 CBM-I 应用于青少年之前,需要研究确定出现症状变化的最佳训练参数。
