The Rorschach Ego Impairment Index (EII / EII-2; Perry & Viglione, 1991; Viglione, Perry, & Meyer, 2003) was created to assess one's capacity to organize and utilize internal resources for coping with demands of both internal and external stressors. The scale is scored from Comprehensive System (CS; Exner, 2003) variables, and has good psychometric qualities (Perry & Braff, 1994; Perry, McDougall, & Viglione, 1995; Stokes et al., 2003); however, the use of behavioral criterion variables has been relatively infrequent in the EII validity literature (Cadenhead, Perry, & Braff, 1996; Perry & Braff, 1994). Further, few studies have investigated the incremental validity of the EII beyond self-report measures of distress, and none have examined its ability to predict long-term health outcomes in a prospective cohort (Dawes, 1999; Perry, 2001; Perry & Viglione, 1991; Stokes et al., 2003). The proposed study examined the predictive construct validity of the EII-2 using data from the prospective Johns Hopkins Precursors Study dataset. It was hypothesized that EII-2 scores would predict the cumulative incidences of depression, mortality, and divorce over time; the cumulative incidence of depression and mortality over time would be significantly greater for high EII-2 scorers than low EII-2 scorers; EII-2 scores would predict later life psychological health; the interpersonal components of the EII-2 (GHR, PHR) would predict later life psychological health better than the thought disorder component (WSum6), which would predict better than a combined interpersonal / thought disorder component (M-), and all of these components would predict better than primitive contents; higher EII-2 scores (more ego impairment) would correlate significantly and negatively with later life physical health, the use of preventative health services, and perceived social support, but significantly and positively correlate with later life alcohol use, job dissatisfaction, and an aggregate index of all (open full item for complete abstract)
