Cognitive models of psychopathology posit that the content or focus of information-processing biases (e.g., attentional biases) is disorder specific: Depression is hypothesized to be characterized by attentional biases specifically for depression-relevant stimuli (e.g., sad facial expressions), whereas anxiety should relate particularly to attentional biases to threat-relevant stimuli (e.g., angry faces). However, little research has investigated this specificity hypothesis and none with a sample of youths. The present study examined attentional biases to emotional faces (sad, angry, and happy compared with neutral) in groups of pure depressed, pure anxious, comorbid depressed and anxious, and control youths (ages 9-17 years; N = 161). Consistent with cognitive models, pure depressed and pure anxious youths exhibited attentional biases specifically to sad and angry faces, respectively, whereas comorbid youths exhibited attentional biases to both facial expressions. In addition, control youths exhibited attentional avoidance of sad faces, and comorbid boys avoided happy faces. Overall, findings suggest that cognitive biases and processing of particular emotional information are specific to pure clinical depression and anxiety, and results inform etiological models of potentially specific processes that are associated with internalizing disorders among youths.
心理病理学的认知模型假设,信息处理偏差的内容或焦点(例如,注意力偏差)是特定于障碍的:抑郁症被假设为以对抑郁相关刺激(例如,悲伤的面部表情)的注意力偏差为特征,而焦虑应该与对威胁相关刺激(例如,愤怒的面孔)的注意力偏差特别相关。然而,很少有研究调查这种特异性假设,也没有研究是针对青少年样本的。本研究在纯抑郁、纯焦虑、共病抑郁和焦虑以及对照组青少年(年龄 9-17 岁;N=161)群体中考察了对情绪面孔(悲伤、愤怒和快乐与中性面孔)的注意力偏差。与认知模型一致,纯抑郁和纯焦虑的青少年分别表现出对悲伤和愤怒面孔的注意力偏差,而共病青少年则对这两种面部表情都表现出注意力偏差。此外,对照组青少年表现出对悲伤面孔的注意力回避,而共病男孩则回避快乐面孔。总的来说,这些发现表明,认知偏差和对特定情绪信息的处理是特定于单纯的临床抑郁症和焦虑症的,研究结果为青少年内化障碍相关的潜在特定过程的病因学模型提供了信息。
