The clinical utility of the MMPI-2 in diagnosing unipolar depression among male alcoholics.

The correspondence between Scale 2 elevations on the MMPI-2 and SCID-diagnosed unipolar depression (major depression and dysthymia) and alcohol-induced depression was evaluated among 106 consecutive male admissions to an inpatient alcohol treatment unit. Valid profiles were obtained from 87 subjects, 15% of whom were diagnosed with unipolar depression and another 4.5% with presumed alcohol-induced depression. The sensitivity of Scale 2 (the probability that a depressed subject would obtain an elevated score) ranged from .19 to .42. Positive predictive power (the probability that a subject who obtained an elevated score had a depressive disorder) ranged from .23 to .38. Neither Scale 2 alone nor Scale 2 paired in 2-point code types predicted the presence or absence of comorbid depressive disorders among male alcoholics.
