The relationship between MCMI subtlety and severity
1Department of Psychology, Marquette University, Milwaukee, WI 53233, USA.
Abstract:
Wierzbicki (Wierzbicki & Daleiden, 1993; Wierzbicki & Howard, 1992) has suggested that the Subtle-Obvious distinction may be useful for detecting faking on the Millon Clinical Multiaxial Inventory (MCMI; Millon, 1983). This study examined Schretlen's (1990) criticism that, on the MMPI, subtlety is confounded with severity. Nine clinical psychology graduate students rated MCMI items for severity. Severity was significantly correlated (r = -.48) with item subtlety. However, this association was lower than that reported by Schretlen on the MMPI.
Insights
The Subtle-Obvious distinction may help detect faking on psychological tests. However, this study found subtlety is correlated with symptom severity on the Millon Clinical Multiaxial Inventory.
Area of Science:
- Psychological Assessment
- Clinical Psychology
- Psychometrics
Background:
- The Subtle-Obvious distinction is proposed as a method for detecting response distortion in psychological assessments.
- Previous research suggested this distinction could identify faking on the Millon Clinical Multiaxial Inventory (MCMI).
- A criticism posited that subtlety might be confounded with symptom severity, particularly on the Minnesota Multiphasic Personality Inventory (MMPI).
Discussion:
- This study investigated the relationship between item subtlety and symptom severity for the MCMI.
- Graduate students rated MCMI items on their severity.
- The correlation between severity and subtlety was examined to address concerns about confounding variables.
Key Insights:
- A significant negative correlation (r = -.48) was found between MCMI item severity and item subtlety.
- This association indicates that more severe symptoms tend to be associated with less subtle (more obvious) items.
- The observed correlation between subtlety and severity on the MCMI was lower than previously reported for the MMPI.
Outlook:
- Further research is needed to clarify the utility of the Subtle-Obvious distinction in detecting faking across different assessment instruments.
- Investigating the MMPI and MCMI subtlety-severity relationship in clinical populations could provide valuable insights.
- Exploring alternative methods for detecting response distortion in psychological testing remains an important area for future study.

Multiple Comparison Tests
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
