本研究的主要目的是验证阳性与阴性症状量表（PANSS）的五因子（阴性、阳性、兴奋、抑郁和认知）结构的稳定性。在两个不同人群的精神分裂症患者：一个在复发，另一个在慢性期的疾病的PANSS的强迫五因素结构的心理测量学特性（效度和信度）进行了探讨。342例精神分裂症患者符合DSM-Ⅲ-R诊断标准。复发118例（34.5%），慢性期224例（65.5%）。强迫五因素主成分分析解释了复发患者总方差的64.3%，慢性患者总方差的62.1%。与复发患者相比，慢性患者的抑郁和兴奋因素顺序颠倒。除认知因素外，复发和慢性患者的五因素结构的内部一致性良好（Cronbach's alpha > 0.70）。总之，五个维度（消极，积极，兴奋，抑郁和认知）是必要的，以解释PANSS所描述的精神分裂症复发和慢性精神分裂症患者的各个临床方面。(C)2000 Elsevier Science B.

The main objective of the study was to verify the stability of the five-factor (negative, positive, excitation, depression and cognitive) structure of the Positive and Negative Syndrome Scale (PANSS). The psychometric properties (validity and reliability) of the forced five-factor structure of the PANSS were explored in two different populations of schizophrenic patients: one in relapse and the other in the chronic phase of the disease. Three hundred and forty-two schizophrenic patients according to DSM-III-R criteria were involved. One hundred and eighteen (34.5%) patients were in relapse, and 224 (65.5%) were in the chronic phase. The forced five-factor principal-component analysis explained 64.3% of the total variance in the relapse patients and 62.1% in the chronic patients. The order of the factors was reversed for the depression and excitation factors in chronic patients compared with patients in relapse. The internal consistency of this five-factor structure was good (Cronbach's alpha > 0.70) in the relapse and chronic patients, except for the cognitive factor. In conclusion, five dimensions (negative, positive, excitation, depression and cognition) are necessary to account for the various clinical aspects of schizophrenia described by PANSS in relapse and chronic schizophrenic patients.
