Assessing somatization in functional gastrointestinal disorders: integration of different criteria.

BACKGROUND: Psychiatric assessment of somatization (the tendency to experience and communicate psychological distress in the form of physical symptoms and to seek medical help for them) currently rests on DSM criteria. An alternative diagnostic and conceptual framework has been proposed by an international group of psychosomatic investigators. The aim of this study was to compare these new criteria (Diagnostic Criteria for Psychosomatic Research, DCPR) with DSM-IV in a population where a high prevalence of psychosocial problems is expected (functional gastrointestinal disorders, FGID). METHOD: One hundred and ninety consecutive patients with FGID in a tertiary care center were assessed according to DSM-IV and DCPR criteria. RESULTS: The number of the 12 DCPR diagnoses was almost double that of DSM diagnoses. Only 9% of the patients were not identified by DCPR criteria, whereas this occurred in 25% of patients using DSM criteria. While patients who were given a DSM diagnosis frequently had additional DCPR diagnoses, many patients with DCPR syndromes did not fulfill any DSM criteria. Four DCPR syndromes appared to be particularly frequent and accounted for almost three quarters of the total diagnoses (alexithymia, persistent somatization, functional symptoms secondary to a psychiatric disorder, demoralization). CONCLUSIONS: The joint use of DSM and DCPR criteria was found to improve the identification of psychological factors in FGID. The results may pave the way for changes in DSM classification of somatoform disorders.

Criterion-related validity of the diagnostic criteria for psychosomatic research for alexithymia in patients with functional gastrointestinal disorders.

BACKGROUND: Because of criticism made against psychiatric assessment of somatization, alternative Diagnostic Criteria for Psychosomatic Research (DCPR) have been proposed by an international group of psychosomatic investigators. One of these criteria concerns the alexithymia construct. The main aim of the present study was to investigate the criterion-related validity of the DCPR for alexithymia syndrome (DCPR-A). A secondary aim was to explore the relationship between alexithymia and depressed mood. METHOD: The study included 190 consecutive outpatients with functional gastrointestinal disorders. Alexithymia was assessed by means of the DCPR-A and the 20-item Toronto Alexithymia Scale (TAS-20). Depressed mood was assessed on the basis of the Depression subscale of the Hospital Anxiety and Depression Scale (HDS) and the DSM-IV criteria. RESULTS: The sensitivity of the DCPR-A together with the TAS-20 was 70.2%, specificity was 81.6%, positive predictive power 88.9%, negative predictive power 66.0% and overall hit rate 46.8%. DCPR-A positives scored significantly higher than DCPR-A negatives on the TAS-20 scores (t = 9.86, p < 0.001). The TAS-20 was not associated with any measure of depression, while the DCPR-A was significantly associated with the HDS and DSM-IV criteria. CONCLUSIONS: The DCPR-A had adequate sensitivity, specificity and accuracy, thus proving that the criterion has good validity. The differences in association found between alexithymia and depression suggest that they may be due to differences in the methods of investigation rather than to the constructs per se.

[Pathology of adaptation according to Sami-Ali and index of conformity to the Rorschach test in ulcerative rectocolitis].

According to Sami-Ali's theoretical model the psychosomatic personality is characterised by an adaptation pathology whose main elements are the repression of imaginative thought and conformity to socio-cultural standards. This study examines adaptation pathology using the Rorschach test. The Authors have formulated a conformity index by relating kinestheses (M) and banal perceptions (BAN). The study was carried out on a sample of 41 patients suffering from ulcerous rectocolitis comprising 24 males and 17 women with a mean age of 32 years. As expected in the hypothesis 97.6% of the sample showed M values below the norm, and 68.3% had Ban values higher than normal, whereas the conformity index was positive and tendentially positive in 65.9% of cases. These findings confirm Sami-Ali's theory. Subjects with ulcerous rectocolitis form part of the adaptation pathology which characterised the psychosomatic personality, with an inverse proportionality between imaginative activity (kinesthesia below normal) and conformism (banal perceptions above the norm).

[Psychological disorders in patients with enterostomy. The influence of age].

A retrospective study of patients who had undergone enterostomy and subsequent follow-up in the past 9 years was carried out with the aim of identifying differences with relation to symptoms of depression, the deterioration of social relations and sexual disturbances between elderly (age greater than or equal to 65) and non-elderly patients (age less than 65). Depressive symptoms were present to a greater extent in elderly (48.6%) than in non-elderly patients (34.8%), whereas sexual disturbances were experienced more in non-elderly (34.8%) than elderly (21.6%) patients. No striking differences were noted with regard to the deterioration of social relations. The differences observed, although marked in terms of percentage, were not statistically significant given the relatively small number of cases examined.
