Associations between supernormality ('faking good'), narcissism and depression: An exploratory study in a clinical sample

We explored underreporting of mental health symptoms and its correlates in adults receiving psychological treatment. We administered the Supernormality Scale (SS), the Minnesota Multiple Personality Inventory-2 (Restructured Form, MMPI-2-RF), the Narcissistic Personality Inventory (NPI) and the Beck Depression Inventory-II (BDI-2) to 147 patients at the start of their treatment. Supernormality (i.e., denial of common symptoms) was positively associated with MMPI-2(-RF) faking good parameters supporting the construct validity of the SS. Narcissism was negatively related to self-reported depression symptoms, but this association failed to reach significance (r= -.15,p= .07). This suggests that patients high on grandiose/overt narcissism might tend to deny common symptoms. The link between supernormality and depression symptoms as measured by the BDI-2 was substantial and negative (r= -.72). Our data suggest that supernormality is associated with constricted self-reports of depression. Given the clinical relevance of symptom underreporting, our preliminary findings require a large-scale replication.
