临床记忆量表在帕金森病患者中的内部信度和结构效度分析

摘要

Objective To study the internal reliability and construct validity of Clinical Memory Scale in patients with Parkinson's dis-ease (PD). Methods 155 PD patients were assessed with Clinical Memory Scale. Results Cronbach'sαof Clinical Memory Scale was 0.772, while split-half reliability coefficient was 0.770. One factor had been extracted with factor analysis, which explained 53.18%of variance, and loaded 5 items. Conclusion Clinical Memory Scale is available for PD patients with acceptable internal reliability and construct validity.%目的：研究临床记忆量表在帕金森病患者中内部信度和结构效度。方法对155例帕金森病患者进行临床记忆量表测评。结果临床记忆量表的内部一致性信度Cronbachα=0.772，分半信度系数为0.770；因子分析共提取出一个公因子，可解释总变异的53.18%，5个单项均负荷于此因子。结论临床记忆量表用于评价帕金森病患者的记忆损害，其内部信度及结构效度较好。
