The Positive and Negative Syndrome Scale (PANSS) was developed to assess symptomatology in inpatients with schizophrenia. We examined its reliability and validity among outpatients with schizophrenia (N = 75) and mood disorders (N = 61). Because the hypothesized three-scale structure of the PANSS has not been supported by existing research, we also examined its factor structure. Interrater reliability for individual items and the positive and negative scales was demonstrated. Evidence supported the internal consistency of each scale in the overall sample and the schizophrenia group but was mixed among those with mood disorders. PANSS scores were higher in the schizophrenia group. These scores, in turn, were lower than those generally reported among inpatients with schizophrenia, providing known-groups validity evidence. Four of five factors were similar to those reported among inpatients with schizophrenia. Together, these results support the use of the PANSS among outpatients and reinforce existing support for assessing positive and negative symptoms in mood disorders.
阳性和阴性症状量表（PANSS）是为评估精神分裂症住院患者的症状学而编制的。我们在精神分裂症门诊患者（N = 75）和心境障碍门诊患者（N = 61）中检验了该量表的信度和效度。由于现有研究并未支持PANSS假设的三分量表结构，我们还检验了其因子结构。研究证明了各条目以及阳性和阴性量表的评分者间信度。证据支持了总体样本和精神分裂症组中各量表的内部一致性，但在心境障碍患者中结果不一。精神分裂症组的PANSS得分更高。反过来，这些得分又低于精神分裂症住院患者中通常报告的得分，从而提供了已知群体效度证据。五个因子中的四个与精神分裂症住院患者中报告的因子相似。总体而言，这些结果支持在门诊患者中使用PANSS，并强化了现有对评估心境障碍中阳性和阴性症状的支持。
