The potential role of high or low birthweight as risk factor for adult schizophrenia.

Objective: Obstetric complications may be an important factor in the development of schizophrenia. The aim of this study is to evaluate the role of these complications in the development of schizophrenia in adult life, with particular attention to the potential role of birth weight.

Method: We carried out a case-control study, comprising schizophrenics and patients with diseases of the schizophrenia spectrum as cases, and their healthy male brothers as controls.

Alexithymia and global psychosocial functioning: a study on patients with skin disease.

Objective: The relationship between alexithymia and psychosocial functioning has been investigated in a few studies using indirect measures of adaptation. We aimed at directly evaluating the relationship between alexithymia and global psychosocial functioning, as measured by a standardised scale.

Methods: A large, consecutive sample of dermatological inpatients (N=545) completed the 20-item Toronto Alexithymia Scale and the Skindex-29 and were administered the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I disorders and the Global Assessment of Functioning (GAF) scale.

Integration of multiple criteria for psychosomatic assessment of dermatological patients.

Psychological distress has been frequently reported in the setting of skin disorders. The Diagnostic Criteria for Psychosomatic Research (DCPR) have been found to yield valuable integrative information, in addition to DSM-IV nosology, in a variety of medical diseases. The aim of this study was to verify whether this integration could also be helpful in dermatology.

Screening for psychiatric disorders in patients with skin diseases: a performance study of the 12-item General Health Questionnaire.

Objective: Although psychiatric disorders are frequent among dermatological patients, no study has formally assessed the performance of any psychiatric screening questionnaire in dermatological practice. This study tested the ability of the 12-item General Health Questionnaire (GHQ-12) to identify psychiatric morbidity in dermatological patients.

Methods: A sample of 521 adult inpatients (81% of all eligible patients) completed the GHQ-12 and were administered the Structured Clinical Interview for DSM-IV Axis I disorders (SCID-I) by a trained mental health professional masked to GHQ-12 score.
