Response style and the revised NEO personality inventory: validity scales and spousal ratings in a Chinese psychiatric sample.

Abstract

The effects of response style bias on profile scores from the family of NEO scales and the resultant influence of response style on the predictive capacity of these scales continues to be debated. In this study, a large sample of Chinese psychiatric patients were categorized into four response style groups based on their scores from recently developed "validity" scales for the revised NEO Personality Inventory (NEO PI-R). Mean differences and correlations between self-report and spousal ratings of these patients were examined for the NEO PI-R domain and facet scales. Excessive positive self-presentation bias resulted in mean differences between the self-report and spousal ratings for N and E. Correlations between self-report and spousal ratings were reduced in patients engaging in positive self-presentational bias compared to those who were not so categorized on three of the five NEO PI-R scales. However, these results were manifest only in a sub-sample of psychotic patients. Negative self-presentational bias did not affect mean differences or diminish the correlations between the self-report and spousal ratings.
