Psychological Profiles in Ulcerative Colitis and Crohn's Disease: Distinct Emotional and Behavioral Patterns.

Background/

Objectives

Ulcerative colitis (UC) and Crohn's disease (CD) are two forms of inflammatory bowel disease (IBD), which, despite their shared inflammatory nature, differ markedly in clinical presentation and disease course. In this study, we aimed to explore whether these clinical differences are also reflected at the psychological level. Specifically, we sought to delineate the personality characteristics of a sample of patients with IBD and to investigate psychological and psychopathological differences between individuals with UC and CD.

Methods

We enrolled 29 (44.61%) UC patients and 36 (55.39%) CD patients, all aged 18 years or older. Each participant completed the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), which was subsequently scored and interpreted by trained psychologists. The MMPI-2 is a 567-item inventory with dichotomous answers (true/false), providing measures of a wide range of symptoms, beliefs, attitudes, and personality traits.

Results

The total sample showed clinically significant elevations on hypochondriasis (Hs), health concerns (HEA), general health concerns (HEA3), and physical malfunctioning (D3) scales. UC patients had statistically significant higher scores on hypomania (p = 0.043), lack of ego mastery-defective inhibition (p = 0.006), and fears (p = 0.038) scales than CD patients. On the other hand, CD patients showed statistically significant higher scores on the Overcontrolled Hostility scale (p = 0.043).

Conclusions

Both groups of patients experience emotional difficulties related to their clinical conditions, leading to an increased preoccupation with bodily symptoms and illness. These aspects appear to be accompanied by shifts in mood towards a more depressive state. Notably, the UC group demonstrates a greater degree of impairment compared to the CD group, with experiences of anxiety, stress, difficulties in emotional control, and emerging relational challenges.
