Internal Reliability and Construct Validity of Clinical Memory Scale in Patients with Parkinson's Disease / 中国康复理论与实践

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.
