Eleven factors were obtained by factor analysing the CPRS results from a longitudinal treatment process study in chronic schizophrenics during maintenance phase. Such factors may give more reliable information than the single item. Two factors--"anxiety-depression-asthenia" and "psychotic" (psychotic schizophrenic symptoms and signs)--nonpsychotic rating of anxiety and depressive symptoms as well as definite psychotic-schizophrenic symptoms, respectively--demonstrated special value for the clinical work, i.e. being relevant instrument for monitoring a treatment process.
通过对慢性精神分裂症患者维持期纵向治疗过程研究中的CPRS结果进行因子分析，获得了11个因子。这些因子可能比单个项目提供更可靠的信息。两个因子——“焦虑-抑郁-虚弱”和“精神病性”（精神病性精神分裂症症状和体征）——分别为焦虑和抑郁症状的非精神病性评分以及明确的精神病性精神分裂症症状，对临床工作具有特殊价值，即作为监测治疗过程的相关工具。
