Social anxiety commonly occurs across the course of schizophrenia, including in the premorbid and prodromal phases of psychotic disorders. Some have posited that social anxiety may exist on a continuum with paranoia; however, empirical data are lacking. The study aim was to determine whether attenuated positive psychotic symptoms are related to social anxiety. Young adults (N=1378) were administered the Prodromal Questionnaire (PQ), which measures attenuated positive psychotic symptoms (APPS), and the Social Phobia Scale (SPS), which measures a subset of social anxiety symptoms. Confirmatory factor analyses were conducted to address the extent to which social anxiety and APPS tap distinct dimensions. Confirmatory factor analyses support the existence of a separate social anxiety factor scale and four separate, though interrelated, APPS factor domains (unusual thought content, paranoia/suspiciousness, disorganized thinking, and perceptual abnormalities). Additionally, social anxiety was significantly, but not differently related to each APPS domain, although the magnitude was reduced between social anxiety and distressing APPS. The current study suggests that social anxiety and attenuated positive psychotic symptoms are separable constructs, but are significantly associated with each other.
社交焦虑症常见于精神分裂症的病程中，包括精神病前和前驱期。有人提出，社交焦虑症可能与妄想存在连续统关系；然而，缺乏经验数据。本研究旨在确定减轻的阳性精神病症状是否与社交焦虑症有关。研究对 1378 名年轻人进行了前驱期问卷（PQ）和社交恐惧症量表（SPS）的测试，前者用于测量减轻的阳性精神病症状（APPS），后者用于测量社交焦虑症状的一个子集。通过进行验证性因子分析来确定社交焦虑和 APPS 在多大程度上反映了不同的维度。验证性因子分析支持社交焦虑因子量表和四个独立但相互关联的 APPS 因子域（异常思维内容、妄想/多疑、思维混乱和知觉异常）的存在。此外，社交焦虑与每个 APPS 域均显著相关，但与困扰性 APPS 的相关性不同，尽管其相关性在社交焦虑和困扰性 APPS 之间有所减弱。本研究表明，社交焦虑和减轻的阳性精神病症状是可分离的结构，但它们之间存在显著的关联。
