Aims:
To propose an original evaluation and validation of the Clock Face Test (CFT).
Method:
Outpatients; 163 elderly people, aged over 65 years. Factory analysis, Student's test.
Results:
The test shows a positive correlation with Folstein's MMSE (r = 0.769) and Signoret's BEC 96 (r = 0.644), a good specificity (75% with MMSE; 79% with BEC 96) and a good sensitivity (87% with MMSE; 74% with BEC 96). Four factors are identified by factory analysis; 74% of the variancy is explained by the first three factors.
Conclusion:
The CFT is a valid tool, easy to conduct. Several applications are possible for diagnosis, psychometric control and therapeutic trials.
