[Are there Associations between Embitterment and Clinical as well as Personality Variables by Psychosomatically Ill...

Understanding of bitterness ranges from a negative general human emotion to a destructive complex affekt due to a non adequate processed affront or resentment.

Relevant associations between kinds of bitterness and clinical as well as personality-related variables in hospitalized psychosomatic patients were examined.

Prospective naturalistic study over 14 months of consecutive admitted psychosomatic patients without exclusion criteria (N=166). General bitterness and 4 subscales were investigated on the basis of the Berner Verbitterungs-Inventar (BVI), personality traits on the basis of BFI-10, and clinical variables mainly on the basis of validated instruments (HoNOS, BDI, HADS, GAF, CGI, IIP-D, BSCL, comorbidity, duration of illness and structure as well as conflict-load according to OPD-2). Differences among levels of bitterness were examined with ANOVA tests, relationships between bitterness and clinical as well as personality-related variables using multivariate linear and multinomial regression models.

The general bitterness falls within the average range. ANOVA models show higher scores for neuroticism, IIP, BDI, HADS, and BSCL when bitterness is above-average. In multivariate regression analyses, BDI, BSCL and neuroticism are positively associated with bitterness, whereas GAF, illness duration, and conscientiousness are negatively associated with bitterness. Diagnoses, severity of disease and burden of conflicts as well as level of organization of personality are not associated with bitterness. Models explain 11-39% of variance of bitterness.

Bitterness in psychosomatic patients is hardly associated with personality variables, diagnoses, and psychopathological burden with the exception of depressiveness and neuroticism. Burden of interpersonal concerns may better explain bitterness than psychopathology or personality.

Bitterness could be interpreted as a theoretical construct widely independent from severity of disease, personality, and diagnosis, showing importance in clinical practice.
