Social phobia is increasingly recognized as a prevalent and socially impairing mental disorder. However, little data is available regarding the general and disease-specific impairments and disabilities associated with social phobia. Furthermore, most studies have not controlled for the confounding effects of comorbid conditions.

This study investigates: (a) the generic quality of life; (b) work productivity; and, (c) various other disorder-specific social impairments in current cases with pure (n = 65), comorbid (n = 51) and subthreshold (n = 34) DSM-IIIR social phobia as compared to controls with no social phobia (subjects with a history of herpes infections).

Social phobia cases reported a mean illness duration of 22.9 years with onset in childhood or adolescence. Current quality of life, as assessed by the SF-36, was significantly reduced in all social phobia groups, particularly in the scales measuring vitality, general health, mental health, role limitations due to emotional health, and social functioning. Comorbid cases revealed more severe reductions than pure and subthreshold social phobics. Findings from the Liebowitz self-rated disability scale indicated that: (a) social phobia affects most areas of life, but in particular education, career, and romantic relationship; (b) the presence of past and current comorbid conditions increases the frequency of disease-specific impairments; and, (c) subthreshold social phobia revealed slightly lower overall impairments than comorbid social phobics. Past week work productivity of social phobics was significantly diminished as indicated by: (a) a three-fold higher rate of unemployed cases; (b) elevated rates of work hours missed due to social phobia problems; and, (c) a reduced work performance.

Overall, these findings underline that social phobia in our sample of adults, whether comorbid, subthreshold, or pure was a persisting and impairing condition, resulting in considerable subjective suffering and negative impact on work performance and social relationships. The current disabilities and impairments were usually less pronounced than in the past, presumably due to adaptive behaviors in life style of the respondents. Data also confirmed that social phobia is poorly recognized and rarely treated by the mental health system.

We have studied the occurrence of dual diagnoses (psychoses as well as abuse of either amphetamine, cannabis or opiates) during a 15-year period, among patients treated at Huddinge Hospital, Stockholm, Sweden. The purpose of the study is to evaluate if the different drugs were coupled to different rates of psychiatric co-morbidity. During the period in question, 461, 425 and 371 different patients respectively had been admitted at least once due to dependency on amphetamine, cannabis and opiates. Approximately 30% of the patients with a pure abuse of amphetamine or cannabis and less than 6% of the opiate abusers had been diagnosed at least once with any of the psychoses studied. Comparing the frequency of psychoses among mixed and pure abusers of illegal drugs, with and without a concomitant abuse of alcohol, we found that the co-morbidity rate for mixed opiate abusers increased significantly from 7.2 to 20.2% when alcohol abuse was also present. For abusers of amphetamine and cannabis (both pure and mixed), no differences in co-morbidity rates were seen when an abuse of alcohol was added to that of the drugs. It is difficult to find an explanation for the significant difference between the co-morbidity of pure abuse of amphetamine or cannabis on the one hand and opiates on the other. In conclusion, our findings show that the distribution of psychotic illness is high among abusers of amphetamine and cannabis, in contrast to the generally lower co-morbidity among abusers of opiates. Although these findings are consistent with earlier studies that have shown a propensity for developing psychoses among abusers of amphetamine and cannabis, one should bear in mind that this study is based on inpatients, and is not necessarily representative for all abusers of the drugs in question.

The idea of assessing needs both in individuals and in populations is popular in health and social care, but has serious conceptual shortcomings. The concept of needs does not distinguish between the identification of a problem and its solution. It inhibits a consideration of the probabilities as to how effective various interventions may be in any given case — nor does it reflect the iterative process that is the reality of most health and social care. It does not specify goals and oversimplifies evaluation of outcome because it does not take into account different degrees of change. In assessing population needs, there is the special risk of equating service use with service need, thereby entrenching the status quo. Instead of assessing needs, it is proposed that we identify problems, specify goals and choose interventions on the basis of probabilities of effectiveness. The outcome of any given intervention can be repeatedly reviewed with respect to its goals, and priorities may be reset accordingly.

Although genetic and environmental factors operating before or around the time of birth have been demonstrated to be relevant to the aetiology of the major psychoses, a seasonal variation in the rates of admission of such patients has long been recognised. Few studies have compared first and readmissions. This study examined for seasonal variation of admission in the major psychoses, and compared diagnostic categories by admission status. Patients admitted to Irish psychiatric inpatient facilities between 1989 and 1994 with an ICD-9/10 diagnosis of schizophrenia or affective disorder were identified from the National Psychiatric Inpatient Reporting System (NPIRS). The data were analysed using a hierarchical log linear model, the chi-square test, a Kolmogorov-Smirnov (KS) type statistic, and the method of Walter and Elwood. The hierarchical log linear model demonstrated significant interactions between the month of admission and admission order (change in scaled deviance 28.77, df = 11, P < 0.003). Both first admissions with mania, and readmissions with bipolar affective disorder exhibited significant seasonality. In contrast, only first admissions with schizophrenia showed significant seasonal effects. Although first admissions with mania and readmissions with bipolar disorder both show seasonality, seasonal influences appear to be more relevant to onset of schizophrenia than subsequent relapse.

In this study, a PstI polymorphic site with two individual alleles, namely A1 and A2, was identified within the boundary between intron 1 and exon 2 of the cholecystokinin (CCK) type A receptor gene. The PstI polymorphic site was used as a genetic marker to study its association with psychotic symptoms in schizophrenia. A significant difference in allelic frequency was found between schizophrenic patients with and without auditory hallucinations (χ2 = 6.26, df = 1, P = 0.012), and the odds ratio for the allelic association was 2.21 (95% CI 1.18–4.15) with an attributable fraction of 0.1. The frequency of A1-A1 and A1-A2 genotypes showed a significant excess in schizophrenic patients with auditory hallucinations as compared to those without such symptoms (χ2 = 5.45, df = 1, P = 0.02), and the odds ratio for the genotypic association was 2.27 (95% CI 1.13–4.57) with an attributable fraction of 0.177. The haplotype-based haplotype relative risk (HHRR) test revealed a significant difference between transmitted and non-transmitted alleles in nuclear families of schizophrenic patients with auditory hallucinations (χ2 = 4.54, df = 1,P = 0.033) but not in those of schizophrenic patients without them. The present study suggests that the CCK-A receptor gene may be associated with auditory hallucinations in schizophrenia.

In the present study two broad hypotheses about the origins of self-mutilation in psychiatric patients were evaluated. The first hypothesis states that self-mutilation originates from child abuse and experiences of neglect and is connected to dissociation in later life. The second hypothesis views self-mutilation as the consequence of impulse control problems. To test these two hypotheses, data concerning traumatic childhood experiences and dissociative symptoms (hypothesis 1), as well as data concerning aggressiveness, obsessive-compulsiveness and sensation seeking (hypothesis 2) were collected in a sample of 54 psychiatric inpatients. Twenty-four out of 54 patients (44%) reported having engaged in self-mutilation. Mean age of onset of this behaviour was 23 years. Self-report measures of self-mutilators were more in line with the first than with the second hypothesis. That is, patients who engaged in self-mutilation reported more traumatic childhood experiences and dissociative symptoms than did control patients. The two groups did not differ in terms of aggressiveness, obsessive-compulsiveness, and sensation seeking. In line with earlier studies, the current results indicate that self-mutilating behaviour is linked to a history of abuse and neglect.

The analysis of the geographical distribution of hospital cases is obviously important for the purpose of planning hospital services, but it is of even greater significance in the planning of psychiatric services. This concern motivated our seven-year-long study, which examined hospitalization risks among various categories of psychiatric disorders in the major German city of Hamburg. Our database encompassed 77% (n = 64,000) of all psychiatric admissions in a total of 41 hospitals, most of which are general hospitals. In order to carry out the geographical analysis we employed a new statistical method based on a mixture distribution model. According to our findings, the strongest indications of an increased frequency were among male cases of schizophrenia, drug abuse and organic psychoses, and female cases of neurotic disorders, personality disorders, drug abuse and schizophrenia. We found that some areas are exposed to a risk of hospitalization for these diagnostic categories which is more than 50% above the reference. Contrary to other authors we did not identify an increased frequency of admission concentrated in the inner-city area for any of the diagnostic groups. The risk of hospitalization for schizophrenics was almost entirely associated with the close proximity of psychiatric units, while the risks for neuroses and personality disorders, as well as alcohol and drug abuse, appeared to be concentrated in areas of low social status. However, a statistically relevant correlation between an increased risk of hospitalization and low social status could be determined only for drug abuse and alcoholism. In the end, we did identify two areas in which there was an increased risk of hospitalization for several diagnostic groups, and this information will undoubtedly facilitate the planning of hospital and psychiatric services. The fact that our findings deviate to some extent from other authors – especially with respect to neuroses and personality disorders, but also to addiction – can be attributed to the inclusion of psychiatric cases from general hospitals in our geographic analysis.

A population sample comprised of 765 subjects (367 males and 398 females), in the age range of 15-81 years, completed the EMBU, a reliable questionnaire aimed at assessing experiences of parental rearing, and the TCI, a self-report questionnaire aimed at assessing dimensions of temperament and character. The study had three main aims: 1) to verify, on a larger scale, previous findings suggesting the occurrence of significant associations between experiences of parental rearing and aspects of temperament and character, 2) to assess possible variations in temperament and character in cohorts of subjects who have grown up in different historical epochs, and 3) to investigate to what extent transgenerational differences in parental rearing are detectable in different associations with various dimensions of personality. Several, albeit small, significant and meaningful associations between experiences of parental rearing and both temperament and character dimensions have been found, adding support to the robustness of previously reported results obtained in an independent smaller series. Also, several significant differences among subjects in different age groups have been found, both concerning temperament variables and character dimensions. Finally, the results show that associations between experiences of parental rearing and dimensions of temperament and character are most pronounced in subjects belonging to the youngest cohort and almost nil in the cohort comprising the oldest subjects.

This study validated a French language version of an inventory designed to detect symptoms of depression and anxiety [Goldberg et al, 1987] in a sample of elderly French-speaking inpatients at risk for one of these disorders. Latent trait analysis was used to replicate the structure of the symptoms in the inventory, and receiver operating characteristic analysis was used to assess the performance of the inventory as a screening measure for Major Depressive Episode and Generalised Anxiety Disorder according to DSM-IV criteria. Reflecting the ascertainment of individuals in the sample as being at risk for a disorder, prevalence of individual symptoms was high although the general structure of the inventory was found to be comparable to that found in samples of both community elderly and younger medical patients. ROC analyses showed that the subscales of inventory performed satisfactorily as screening measures for anxiety or depression but lacked specificity for each disorder. In addition to providing further evidence for the utility of this inventory to detect general psychiatric distress in elderly persons, this study provides a valid means of detecting symptoms of depression and anxiety in French speaking groups.

While melancholic (according to DSM) or somatic syndrome (according to ICD) has strong historical roots and substantial empirical verification, the concept of atypical features is relatively new and not sufficiently studied. The aim of the current study was to investigate the reliability of these diagnostic subcategories in patients suffering from major depression in Greece. Forty patients (eight males and 32 females) aged 19-60 years (mean 39.3, sd 12.2) suffering from major depression according to DSM-IV criteria were studied. SCAN v.2.0 was used to assess symptomatology. The presence of each criterion according to DSM-IV and ICD-10 was registered. Frequency tables were developed and factor and cluster analysis were performed. The results of the analysis suggest the existence of three syndromes which roughly reflect the melancholic and atypical but also propose a third, which can be considered as an ‘undifferentiated’ syndrome. The DSM demand that the existence of melancholic features be excluded first and then that diagnosis of atypical features be made was confirmed.

We investigated hospitalization factors in acutely ill patients visited by psychiatrists at home. A series of 100 consecutive calls for psychiatric emergencies of a community mental health centre were investigated with a structured evaluation of psychiatric symptoms and aggressiveness (IEF, GAS, and VSAS). First order interactions were tested, and selected variables were tested with logistic regression analysis. Admission was significantly associated with GAS scores (low scores were found in 92.6% of admitted patients vs. 43.8% of patients not admitted), paranoid delusions (66.7 vs. 39.7%), and lack of social support (70.4 vs. 30.1%). Multivariate analysis confirmed a significant independent effect only for low GAS score and lack of social support. The study replicated some findings from research on hospitalization in emergency wards, while other factors, such as ’diagnosis’ and ’suicide risk’, were not significant.

The prevalence of anxiety disorders and associated DSM-III-R diagnoses were measured in a sample of 80 female adolescents aged between 15 to 20 years consulting an outpatient psychiatric service for adolescents. The suicide attempt group (SA) included 40 patients evaluated within 24 h after attempted suicide. This is compared to 40 consecutive patients consulting the same center but without any history of suicide attempt (the no attempt group, NA).

The global prevalence of anxiety disorders was similar in both groups (SA: 65% vs. NA: 60%, NS) as was the relative importance of the different disorders in each group, generalized anxiety being the most frequent specific anxiety disorder. The most striking difference between the two groups was in the prevalence of affective disorders in 90% (SA) vs. 32.5% (NA) (P < 0.001), leading to high rates of comorbidity on axis I in the SA group. Of the 24 patients with anxiety disorders who attempted suicide, 21 (95%) fulfilled criteria for associated major depression, compared to five out of 21 (24%) patients with anxiety disorders who had not attempted suicide.

Adolescents with anxiety disorders developing major depression are at a high risk for suicide. The depression may be of short duration (less than two weeks) when compared to that of the anxiety disorder (greater than six months). To improve suicide prevention, our findings if confirmed should encourage clinicians to perform a close follow-up of adolescents with anxiety disorders for an early detection of sudden depressive breakdowns.

This paper describes the development and the validation of a questionnaire assessing the opinions of the relatives of patients with schizophrenia on the causes and the social consequences of the disorder. The final version of the questionnaire includes 28 items, grouped in four sub-scales (social restrictions, social distance, utility of treatments, biopsychosocial causes of schizophrenia), whose intra-rater reliability ranges from 0.36 to 0.84. Cronbach's alpha coefficient, which tests the content validity of the sub-scales, ranges from 0.56 to 0.66. Factor analysis identifies two factors (opinions on social consequences and the utility of treatments, and the beliefs on the causes of schizophrenia), which account for the 73% of the total variance. This questionnaire may be particularly useful to assess relatives'beliefs about schizophrenia and to target psychosocial interventions in the families of patients with schizophrenia.

The aims of this study were to assess the quality of life among 120 schizophrenic patients who were attending a psychiatric outpatient department and to investigate which socio-demographic and clinical factors influenced their subjective quality of life. Quality of life was assessed by the Lanchashire quality of life profile, social functioning was judged according to the Global Assessment of Functioning (GAF) scale, and psychopathology was rated by means of the Brief Psychiatric Rating Scale (BPRS). Both objective and subjective life conditions indicated an impaired quality of life for the patients. The areas of finance and work had the largest proportion of dissatisfied patients. Socio-demographic indicators showed to have a weak influence on the patient's self-assessed quality of life while clinical factors, such as psychopathology, strongly influenced the patient's life satisfaction. It is concluded that there is a need for further emphasise on the clinical, financial, and social interventions for this group of patients.

Anorexia nervosa is a severe and complex disorder with incompletely known vulnerability factors. It is generally recognized that anorexia nervosa is a familial disorder, but the majority of twin studies have shown that the concordance rate for monozygotic twins is higher (on average 44%) than for dizygotic twins (on average 12.5%). This difference in concordance rates shows that genetic factors, more than common familial environment, may explain why the `anorexia nervosa' phenotype runs in families. In order to estimate the heritability in the broad sense of anorexia nervosa according to published familial and twin studies, we first assessed the intrapair correlation between monozygotic and dizygotic twins, and secondly calculated the deviation threshold of relatives of affected probands from the relative mean. In this review, we obtained an estimation of the heritability at 0.72 according to all published controlled familial studies (six references quoted in MEDLINE®), and 0.71 for all published twin studies (59 references quoted in MEDLINE®). This estimation is close to the ones previously proposed, between 0.5 and 0.8.

Familial and twin studies may also help to define the boundaries of the phenotype, shedding light on the complex relationship between anorexia nervosa on the one hand, and bulimia nervosa, mood disorders, and alcoholism on the other. Demonstrating the importance of genetic factors in anorexia nervosa, and more specifically for anorexia of the restrictive type, requires not only prospective and adoption studies (which are still lacking), but also genetic polymorphisms analyses, which began very recently.

This study is a careful examination of the relationships between different components of the alexithymia construct and state versus trait anxiety. In order to study the relations between anxiety and alexithymia in a subclinical population, we administered to 125 female college students a test battery including measures of alexithymia (TAS26), state and trait anxiety (STAI) and depression (QD2A). Results indicated positive correlations between depression, anxiety (state and trait) and alexithymia scores. Partial correlations revealed a tight link between trait anxiety and alexithymia. Furthermore, in agreement with the view that alexithymia is a multidimensional construct, the various alexithymia dimensions were found to be diversely correlated with anxiety. On the basis of partial correlation analyses, a descriptive model of the relationships between depression, state anxiety, trait anxiety and alexithymia was postulated. This model was confirmed by pathways analyses.

The need for support and participation in treatment of relatives to voluntarily and compulsorily admitted patients was addressed in a study of the quality of mental health services in two Swedish county councils. The aims of the study were to investigate differences in the above aspects between subgroups of relatives, the differences between two years of investigation, 1986 and 1991, and the differences between relatives of voluntarily and compulsorily admitted patients. The relatives investigated consisted of 79 spouses, 118 parents and 31 grown-up children. The results showed that there were only minor differences between the subgroups concerning their participation in care. Grown-up children experienced significantly less need of support and received less help for this need. In 1991, relatives participated more in the care situation, were more interested in support with regard to their own life situation, and also showed more positive attitudes towards the psychiatric services than in 1986. The relatives of the voluntarily admitted patients felt more involved in the patient's treatment, whereas the relatives of those compulsorily admitted felt less involved and perceived obstacles to admission.

The Continuous Performance Test (CPT) has become an essential constituent of the neuropsychological investigation of schizophrenia. Also, a vast number of brain imaging studies, mostly PET investigations, have employed the CPT as a cognitive challenge and established a relative hypofrontality in schizophrenics compared to controls. The aim of the present investigation was to clarify whether this predescribed hypofrontality could also be verified using functional magnetic resonance imaging (fMRI). 20 healthy volunteers and 14 schizophrenics on stable neuroleptic medication were included. Imaging was performed using the CPT-double-T-version and a clinical 1.5 T MRI-scanner with a single slice technique and a T2*-weighted gradient-echo-sequence. The schizophrenics exhibited a decreased activation in the right mesial prefrontal cortex, the right cingulate and the left thalamus compared to controls. These results obtained by fMRI are discussed in relation to published findings using PET.

The purpose of the present study was to investigate the gender-related differences of clinical features in a sample of obsessive-compulsive (OCD) patients. One hundred and sixty outpatients with a principal diagnosis of obsessive-compulsive disorder (DSM-IV, Y-BOCS = 16) were admitted. Patients were evaluated with a semi-structured interview covering the following areas: socio-demographic data, Axis I diagnoses (DSM-IV), OCD clinical features (age at onset of OC symptoms and disorder, type of onset, life events and type of course). For statistical analysis the sample was subdivided in two groups according to gender. We found an earlier age at onset of OC symptoms and disorder in males; an insidious onset and a chronic course of illness were also observed in that group of patients. Females more frequently showed an acute onset of OCD and an episodic course of illness; they also reported more frequently a stressful event in the year preceding OCD onset. A history of anxiety disorders with onset preceding OCD and hypomanic episodes occurring after OCD onset was significantly more common among males, while females showed more frequently a history of eating disorders. We found three gender-related features of OCD: males show an earlier age at onset with a lower impact of precipitant events in triggering the disorder; OCD seems to occur in a relative high proportion of males who already have phobias and/or tic disorders; and a surfeit of chronic course of the illness in males in comparison with females.

Mood disorders are characterized by manic and depressive episodes alternating with normal mood. While social function is heavily impaired during episodes of illness, there are conflicting opinions about inter-episode function. The present paper focuses on self-esteem and social adjustment in remitted mood disorders patients.

Patients with mood disorders (99 bipolar and 86 major depressive subjects, in remission) were compared with a group of 100 control subjects. The self-esteem scale (SES) and the social adjustment scale (SAS) were used to measure self-esteem and social adjustment, respectively, in both groups of subjects.

Patients with mood disorder exhibited worse social adjustment and lower self-esteem than control subjects.These results strongly confirm previous observations of poor inter-episode function in patients with mood disorder.
