Previous research has utilised the approach-avoidance task (AAT) to measure approach and avoidance action tendencies in socially anxious individuals. "Neutral" social stimuli may be perceived as ambiguous and hence threatening to socially anxious individuals, however it is unclear whether this results in difficulty approaching ambiguous ("neutral") versus unambiguous threat (e.g. disgust) faces (i.e. intolerance of ambiguity). Thirty participants with social anxiety disorder (SADs) and 29 non-anxious controls completed an implicit AAT in which they were instructed to approach or avoid neutral and disgust faces (i.e. pull or push a joystick) based on colour of the picture border. Results indicated that SADs demonstrated greater difficulty approaching neutral relative to disgust faces. Moreover, intolerance for approach of ambiguity predicted social anxiety severity while controlling for the effects of trait anxiety and depression. Our results provide further support for the role of intolerance of ambiguity in SAD.
先前的研究利用趋避任务(AAT)来测量社交焦虑个体的趋近和回避行动倾向。“中性”社会刺激可能被视为模棱两可,因此对社交焦虑个体构成威胁,然而尚不清楚这是否会导致在趋近模棱两可(“中性”)与明确威胁(如厌恶)面孔时出现困难(即对模糊性的不容忍)。30名社交焦虑障碍(SAD)患者和29名非焦虑对照者完成了一项内隐AAT,在该任务中,他们被指示根据图片边框的颜色趋近或回避中性和厌恶面孔(即拉动或推动操纵杆)。结果表明,与厌恶面孔相比,SAD患者在趋近中性面孔时表现出更大的困难。此外,在控制特质焦虑和抑郁影响的同时,对趋近模糊性的不容忍预测了社交焦虑的严重程度。我们的结果为模糊性不容忍在SAD中的作用提供了进一步的支持。
