Aims - Schizophrenia is a severe mental illness that affects 1% of the population. The diagnosis is made according to current diagnostic systems of DSM-1V (American Psychiatric Association, 1994) and ICD-10 (World Health Organisation, 1992), on the basis of characteristic ‘positive’ and ‘negative’ symptoms. The traditional model assumes a categorical view of the schizophrenia syndrome and its core symptoms, in which differences between psychotic symptoms and their normal counterparts are considered to be qualitative. An alternative, dimensional approach assumes that schizophrenia is not a discrete illness entity, but that psychotic symptoms differ in quantitative ways from normal experiences and behaviours. This paper reviews evidence for the continuity of psychotic symptoms with normal experiences, focusing on the symptoms of hallucinations and delusions. Methods - A qualitative review of the relevant literature. Results - The literature suggests that although current epidemiological approaches yield substantial evidence for a continuum view, it is rarely interpreted as such. Conclusions - The traditional concept ofschizophrenia as a homogeneous disease entity has become outdated and is in dire need of a more valid and clinically useful successor.

Objective - This study provides a framework for mental health inequalities beginners. It describes the methods used to measure socio economic inequalities and the inter-relations with different aspects of mental health: residence, mental health services organisation and main diagnostic categories. Method - Literature electronic-search on Medline, Psyclit, Econlit, Social Science Index and SocioSearch usingand relating the key-words inequalities, deprivation, poverty, socio-economic status, social class, occupational class, mental health for the period 1965-2002 (June). The articles selected were integrated with manual search (publications of the same authors, cross-references, working documents and reports of international andregional organisations). Results - Inequality is not an absolute concept and, mainly, it has been changing during the last years. For example, the integration and re-definition of variables that capture, in simple indices, a complex reality; the accent on social more than on economic aspects; the geo-validity and time-reference of the inequality's indices. Moreover, the inequalities could be the result of individual preferences, in this case, the social selectionand social causation issues will raise the suitability for a public intervention. Conclusions - Up to now, research has been mainly concentrated in describing and measuring health inequalities. For designing effective interventions, policy makers need to ground decisions on health-socioeconomic inequalities explanatory models.

Aims - To present the results of an epidemiologic research about psychotropic drug use inSardinia. Methods - Cross-sectional study on a sample of 1040 subjects randomly selected from registers. Setting - Community survey on three areas of Sardinia region. Evaluation: interviews carried out byphysicians by means of Italian version of the Composite International Diagnostic Interview Simplified.Drug consumption was evaluated concerning last week before the interview. Main Outcome Measures: point prevalence. Results - The rate of adults of the general population that consumed benzodiazepines was 10.1%, antidepressants 4.2%, 14.7% of the sample was using psychotropic drugs. 60% of subjects with diagnosis of ICD-10 Depressive Episod did not have the right pharmacologic treatment. A relevant proportion of subjects without lifetime psychiatric diagnosis (anxiety and/or depression) used antidepressants (0.8%). The pharmacologic therapies were managed by psychiatrics in 44.2% of cases, antidepressants were managed by general practitioners in 31.8% of subjects. Conclusions - The research underlines an increase of meet needs in subjects affected by depressive episodes against a previous Sardinian survey carried out over ten years ago. This change is parallel to a more frequent management of therapies by general practitioners. Their role seems to become more relevant in treating depressive illness.

Objective - The question of how many psychopathologic factors are involved in Anorexia Nervosa (AN) and Bulimia Nervosa (BN) has no definite answer. The combination of psychopathology and personality research may shed a light upon the determinants of eating pathology. Methods - The study consists inthe administration of the Temperament and Character Inventory (TCI) and the Eating Disorder Inventory 2 (EDI-2) to 95 outpatient anorectic women (50 restrictive and 45 binge-purging) and to 92 bulimic outpatientwomen (78 with and 14 without purging behaviours). The respective scores of each DCA subgroup are compared. Results - Restricter anorectics are characterised by lower novelty seeking on respect to all the other groups and by a higher self-directedness on respect to bingeing-purging anorectics and purging bulimics. Alsopsychopathologic differences between restricter anorectics and the other groups are extensive. Bingeing-purging anorexia shares many traits with bulimia. Conclusions - In their complex, data suggest and in-deep study aimed to a possible re-classification of EDs which would take impulsiveness in greater consideration. The differences in temperament and character traits may partially be responsible of the repression or discontrol of impulsive eating behaviours in different ED subtypes.
