Modifying threat related biases in attention and interpretation has been shown to successfully reduce global symptoms of anxiety in high anxious and clinically anxious samples (termed Cognitive Bias Modification, CBM). However, the possibility that CBM can be used as a way to prevent anxiety associated with an upcoming real-life stressful event in vulnerable populations has yet to be systematically examined. The present study aimed to assess whether a two-week course of online CBM for interpretations (CBM-I) could reduce social evaluative fear when starting university. Sixty-nine students anxious about starting university completed five sessions of online CBM in the two weeks prior to starting university, or completed a placebo control intervention. Results indicated that CBM-I reduced social evaluative fear from baseline to day one of starting university to a greater extent than the placebo control intervention. Also, there was a greater reduction in state anxiety and a trend indicating a greater reduction in social evaluative fear in the CBM-I group at 4 weeks follow-up. Results suggest that CBM-I could be used as a preventative tool to help reduce anxiety specific to challenging life events.
改变注意力和解释中与威胁相关的偏差已被证明能成功减轻高焦虑和临床焦虑样本中的总体焦虑症状(称为认知偏差修正,CBM)。然而,CBM能否作为一种方法来预防弱势群体中与即将到来的现实生活压力事件相关的焦虑,尚未得到系统研究。本研究旨在评估为期两周的在线解释性CBM课程(CBM-I)在开始上大学时是否能减轻社交评价恐惧。六十九名对上大学感到焦虑的学生在开始上大学前两周完成了五节在线CBM课程,或完成了安慰剂对照干预。结果表明,与安慰剂对照干预相比,CBM-I从基线到开始上大学的第一天能更大程度地减轻社交评价恐惧。此外,在4周随访时,CBM-I组的状态焦虑有更大程度的降低,且有一个趋势表明社交评价恐惧有更大程度的降低。结果表明,CBM-I可作为一种预防工具,帮助减轻特定于具有挑战性的生活事件的焦虑。
