Exploring the Minnesota Multiphasic Personality Inventory (MMPI)-3 in a transgender and gender diverse sample.

Comparisons of transgender and gender diverse (TGD) individuals' mental health functioning with that of cisgender individuals rely almost exclusively on screening measures. The limited research with TGD individuals and omnibus assessment measures has primarily used previous iterations of the Minnesota Multiphasic Personality Inventories (MMPIs). This study sought to examine the psychometric functioning of the MMPI-3 with a TGD community sample (n = 97) and compare mean scores across TGD and cisgender subsamples. We expected MMPI-3 substantive scale reliability to be comparable across all samples and subsamples. Individual MMPI-3 scales were expected to demonstrate appropriate convergent and discriminant validity with relevant criterion measures in the TGD sample. Results generally supported MMPI-3 scale score reliability and validity with TGD individuals. Next, three sets of mean score comparisons were conducted across all MMPI-3 substantive scales: (a) TGD individuals not currently in mental health treatment and the MMPI-3 normative sample, (b) TGD individuals not currently in mental health treatment and TGD individuals currently in mental health treatment, and (c) TGD individuals currently in mental health treatment and an outpatient mental health sample. Fewer differences were found between TGD individuals in our sample who were not currently in mental health treatment and the MMPI-3 normative sample compared to previous work. This initial study indicates that MMPI-3 scales largely have appropriate psychometric properties when administered to a TGD sample and that the test may be helpful in identifying mental health needs of TGD individuals. Needs and directions for further research are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Examining Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) scale scores in a transgender and gender diverse sample.

Transgender and gender diverse (TGD) individuals are at increased risk of various forms of psychopathology. Little research has been conducted with broadband measures of psychopathology and TGD individuals. The present study sought to examine how TGD individuals scored on Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) scales. This included MMPI-2-RF profiles from 85 TGD individuals; 37 were in mental health treatment and 48 of which were not. This study involved three sets of pairwise comparisons on MMPI-2-RF substantive scales via t-tests: (a) TGD individuals not in treatment versus the MMPI-2-RF normative sample, (v) TGD individuals not in treatment versus TGD individuals in treatment, and (c) TGD individuals in treatment versus a large outpatient clinical sample. Compared to the MMPI-2-RF normative sample, TGD individuals not in treatment scored significantly higher on 31 of the MMPI-2-RF substantive scales. Compared to those TGD individuals not in treatment, those in treatment had significantly higher scores on several MMPI-2-RF scales, primarily those of internalizing psychopathology. In the final comparison between TGD individuals in treatment and an outpatient clinical sample, the TGD individuals had some significantly higher and significantly lower scores on MMPI-2-RF substantive scales. Implications regarding minority stress and the current findings are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
