Clinical and Psychological Characteristics of Young Men with Military Adaptation Issues Referred for a Psychiatric Evaluation in South Korea: Latent Profile Analysis of Minnesota Multiphasic Personality Inventory-2 and Temperament and Character Inventory

Abstract

Objective To investigate clinical and psychological characteristics of young men referred for a psychiatric evaluation due to expected unsuitability for military service and identify their heterogeneous subgroups based on the profiles of MMPI-2 and TCI.Methods We conducted a latent profile analysis of 348 men using MMPI-2 and TCI and then a comparative analysis of four latent classes in relation to sociodemographic, clinical, and IQ variables.Results We identified four classes with distinct clinical and psychological features: Class 1 (nonclinical: n=68), Class 2 (internalized: n=129), Class 3 (externalized: n=60), Class 4 (confused: n=91). Class 1 showed no significant psychiatric symptoms and relatively adaptive temperament and characteristics. Class 2 showed relatively higher harm avoidance and introverted traits indicating vulnerability to internalizing disorder. Class 3 was related to higher novelty seeking, impulsivity, and bipolarity. Class 4 showed the most severe clinical symptoms including psychotic experiences with extremely unstable temperament and immature personality. In total, 50–70% participants reported clinically significant depression, anxiety, and suicidal idea. Participants showed lower processing speed index (M=85.9, SD=16.6) than the general population.Conclusion The results suggest that clinical conceptualization and therapeutic intervention considering distinctive features of young men with adaptive problems related to military service are needed.

Latent Classes based on Clinical Symptoms of Military Recruits with Mental Health Issues and Their Distinctive Clinical Responses to Treatment over 6 Months

“…A recent cross-cutting study by Lim et al . [ 7 ] identified four potential subgroups with distinct clinical and psychological characteristics: Class 1 (noncli-nical), Class 2 (internalized), Class 3 (externalized), and Class 4 (confused). These latent subgroups were expected to have substantial differences in clinical prognosis and progress, but no longitudinal studies have previously been performed [ 7 ].…”

“…Classifying a group of recruits or soldiers into different subtypes may lead to different treatment plans and prognoses for each type, and make it possible to manage maladjusted soldiers more systematically.

Correlations between Personality Traits, Patient‐Reported Outcome, and Chronic Prostatitis Symptoms in Men with Different Premature Ejaculation Syndromes

“…As the internal organization of affective, emotional, cognitive, and conceptual systems, personality could determine human unique repose to the environment. Temperament and Character Inventory (TCI) scale is widely used to measure personality [13][14][15]. It has provided a comprehensive biopsychosocial model of personality and divided personality into seven dimensions that vary widely in the general population [16].…”
