Abstract:
Ninety-four workers completed the Minnesota Multiphasic Personality Inventory--2 (MMPI-2) on 2 separate occasions, with an average lag of 21.3 months (SD = 14.1, range = 2-75), within the context of a psychological assessment after suffering an injury due to crime or accident. MMPI-2 profiles were moderately consistent, with correlation coefficients ranging from .61 to .73 for clinical scales, from .52 to .80 for supplementary scales, from .65 to .78 for content scales, and from .32 to .73 for the Personality Psychopathology Five scales (A. R. Harkness, J. L. McNulty, & Y. S. Ben-Porath, 1995). The results suggest that the MMPI-2 provides consistent and stable results across time in injured workers.
