Factor structure of emotional and cognitive behaviors for normals and neurologically impaired patients.
This study examined the factor structure of 68 affective, cognitive, and behavioral symptoms often reported with neurological impairment. The responses of 199 subjects to a behavioral inventory were submitted to an exploratory factor analysis. The results demonstrated that the instrument could be reduced to 16 homogeneous factors, which were able to explain 67% of the instrument's total variability. These factors were entered into a discriminant analysis that examined neurologically impaired patients and normal controls. Eleven of the 16 factors formed a linear composite that discriminated between these two groups with approximately 94% accuracy.
