Factor structure of the Diagnostic Inventory of Personality and Symptoms in a private psychiatric hospital population.

The factor structure of the Diagnostic Inventory of Personality and Symptoms (DIPS) in a private psychiatric patient population was examined (N = 60). Principal components factor analysis with Varimax rotation yielded three well-defined factors, which accounted for 70% of the total variance. These factors can be conceptualized as neurotic, psychotic, and characterological. Results support the construct validity of the Diagnostic Inventory of Personality and Symptoms and are discussed in relation to previous psychometric studies of psychopathology that employed the MMPI.
