[Dissociative disorders].

There are problems with dissociative and conversion disorders with respect to classification, diagnosis, and therapeutic strategies which can only be understood in the historic context of hysteria. Even current diagnostic systems such as the DSM-IV and ICD-10 differ in the classification of such disorders. High prevalence rates ranging from 3% in the general population to 30% in clinical samples underscore their clinical relevance, and traumatic experiences play a major role in the pathogenesis. High rates of comorbid psychiatric disorders, the tendency to chronicity, and concepts of somatization (particularly in patients with conversion disorders) complicate psychotherapeutic approaches. Depending on the treatment goals, both psychodynamic and cognitive-behavioral methods can be applied, supplemented by specific techniques from trauma therapy, e.g. EMDR.

Mental and physical distress is modulated by a polymorphism in the 5-HT transporter gene interacting with social stressors and chronic disease burden.

Previous studies have yielded conflicting results as to the putative role of the functional polymorphism of the promoter region of the serotonin transporter gene (SLC6A4) in the etiology of anxiety-related traits and depressive disorders. Recently, a significant gene-environment interaction was found between life stressors, the short allele of the SLC6A4 polymorphism and depression. The aim of the present study was to investigate if such a gene-environment interaction could be replicated within a different population with a different risk structure. A total of 1005 subjects from a general population sample (Study of Health in Pomerania) were genotyped. Mental and physical distress were assessed on 38 items of the modified complaint scale (BL-38). The interaction between the SLC6A4 genotype, social stressors and chronic diseases with regard to the BL-38 score was evaluated by ANOVA. There was no independent association of genotype with mental and physical distress. However, significant interactions between genotype, unemployment and chronic diseases (F = 6.6; df = 3, 671; P < 0.001) were found in females but not in males. The genotype explained 2% of the total variance of the BL-38 score and 9.1% of the explained variance. The results partly confirm previous findings of a significant gene-environment interaction of the short allele, indicating a higher mental vulnerability to social stressors and chronic diseases. The relevance of this finding is sustained by the fact that the sample characteristics and the risk structure were highly different from previous studies.

Relation between psychological strain and carotid atherosclerosis in a general population.

OBJECTIVE: To investigate the hypothesis that psychological strain is related to carotid atherosclerosis in a large general population sample. METHODS: Intima-media thickness and the prevalence of atherosclerotic plaques in the carotid arteries were quantitatively assessed by high resolution ultrasound among 2164 participants (1112 women and 1052 men, aged 45 to 75 years) of the SHIP (study of health in Pomerania), an epidemiological survey of a random sample of the population of north eastern Germany. Psychological strain was measured by 13 items reflecting typical psychological complaints. Each item was graded by the study participants on a four point scale (from 0, absent, to 3, severe) and a psychological strain score was generated by summing these 13 items. RESULTS: Mean psychological strain score was 10.8 (7.0) (median score 10) among women and 8.5 (6.2) (median score 8) among men. Psychological strain did not predict carotid intima-media thickness among either men or women. However, after adjustment for covariates, high psychological strain and carotid plaques were independently and linearly related, with plaque prevalence odds of 1.03 (95% confidence interval (CI) 1.01 to 1.05, p = 0.009) per increment of the psychological strain score among women and 1.04 (95% CI 1.01 to 1.07, p = 0.003) among men. CONCLUSIONS: This study identified a relation between general psychological strain and carotid atherosclerosis.

[Effect of temperament, effect of alcohol expectancies and peer group on amount of drinking and alcohol-related problems in adolescence].

OBJECTIVE: The purpose of this longitudinal study was to investigate the relationship between temperament (novelty seeking, harm avoidance and reward dependence), alcohol expectancies, membership in a deviant/substance-using peergroup and drinking behaviour of adolescents drawn from a general population. METHODS: 147 adolescents about 15 years of age were interviewed and completed several self-rating questionnaires. We gathered additional information by interviewing their parents. One year after the initial assessment the adolescents only were interviewed and given questionnaires again. RESULTS: Adolescents with alcohol problems at the time of the second interview reported less harm avoidance, less reward dependence, and were more likely to be a member of a deviant/substance-using peergroup a year before, compared to offspring without alcohol problems. Furthermore, they held more positive alcohol expectancies than adolescents without alcohol problems. Taking into account the quantity of alcohol consumed per occasion, all results were confirmed, but temperament did not predict the extend of alcohol consumed after one year. CONCLUSIONS: Alcohol expectancies and peer group deviance/substance-use are strongly associated to alcohol problems and the amount of alcohol consumed. Therefore, they should be the focus of prevention and intervention in this age group.

[The "AMDP scale for dissociation and conversion (AMDP-DK)": development of an observer-rated scale and first psychometric properties].

The AMDP scale for dissociation and conversion (AMDP-DK) represents an observer-rated scale for the assessment of dissociative and conversive phenomena, which closes the gap between available self-report questionnaires and time-consuming structured interviews with their respective disadvantages. The instrument comprises 30 operationalized items, which are rated according to the AMDP rules, and which are theoretically-driven divided into the subscales dissociation (15 items), conversion (9 items) and a "formal" dimension (6 items) to cover associated phenomena. In a sample of psychiatric inpatients (n = 73) the covered symptoms showed a great variety of frequency and intensity. The AMDP-DK and its subscales had good internal consistency (Cronbachs alpha between 0.76 and 0.85). A factor-analysis mostly replicated the theoretically constructed subscales. The convergent and divergent validity of the scale was good, as well as its ability to discriminate between high- and low-dissociating patients. The findings are discussed with regard to the psychometric properties and the relevance for the theories of dissociation and conversion.

[Diagnosis related groups in psychiatry and psychotherapy--alternatives to DRGs].

Diagnosis related groups (DRGs) will be introduced in Germany in 2003 as a basis for hospital funding in all areas except for psychiatry and psychotherapeutic medicine. The following article provides an overview of the use of alternative casemix-systems in the treatment of patients with mental disorders. Overall, DRGs and alternative systems have proven to be poor predictors of resource consumption due to the high variation in the length of stay and the variable treatment opportunities. Therefore, a DRG-system must include the possibility of coded therapeutic treatments, analogous to the procedures used in surgical DRGs, in order to integrate psychiatry and psychotherapeutic medicine into a DRG-based payment system.

Gender differences in unipolar depression: a general population survey of adults between age 18 to 64 of German nationality.

BACKGROUND: Several studies from different epidemiological backgrounds have shown that unipolar depression is more prevalent in females than in males. This study examines gender differences in depression in a sample of 4075 probands recruited representatively from the general population in the northern German epidemiological catchment area of Lübeck. METHODS: Probands were interviewed with M-CIDI by lay interviewers. RESULTS: Being married only seems to increase the female depression risk when having children, while higher education reduced female excess; both male and female risk for depression raised sharply in separated, divorced and widowed probands. Not being employed was associated with an increased risk in male depression whereas in females risk was nearly unchanged. The gender ratio increased with the minimum number of depressive symptoms. Female excess was not reduced by a higher degree of subjective impairment or melancholic features. Females also predominated in longer episode durations. Female excess in the total group emerged beginning from adolescence with a tendency for a male excess in the prepubescent ages. No birth cohort effect was observed. LIMITATIONS: The cross-sectional design of this study precluded causal analysis of reported associations and some retrospective assessments are error-prone because of recall bias. CONCLUSIONS: We support previous findings of variations in gender differences in depression, however observed social parameter influences underline the need for a more detailed analysis of subgroups and underlying psychological mechanisms.

[Alcohol problems in adolescence with reference to high risk children of alcoholic parents. Results of a family study in Mecklenburg Vorpommern].

In earlier studies, children of alcoholics (COAs) reported more alcohol and drug problems and higher levels of maladaptive behaviour and psychiatric distress than non-COAs. However, increased exposure to drugs and alcohol among COAs does not fully explain this phenomenon. In our family-based study design, we were able to investigate specific risk factors for alcohol problems in adolescence. In a first step, we compared a variety of psychosocial risk factors in 90 adolescents (12-18 years of age) from families with at least one alcohol-abusing parent with those of 90 adolescents of parents without alcohol disorders. In a second step, we investigated the meaning of all included risk factors for alcohol problems of the adolescents. Our results give some support to the existence of a lower extent of emotional warmth and support by parents of children in the COA sample. Moreover, males of the COA group reported more parental rejection and higher values on measures of attention problems and anxiety/depression than controls, whereas there were no such differences between females of the COA group and their control counterparts. Additionally, logistic regression analysis revealed that only the membership in a substance-using peer group and higher age are important risk factors for alcohol problems during adolescence. Considering our results, it is of great importance (a) to identify families at risk at the earliest possible stage and (b) to develop intervention and prevention programs further for parents and children to increase social competence and protect children at risk from later alcohol abuse.

[The "AMDP-rating scale for obsessive-compulsive symptoms": The 2nd version].

The "Association of Methodology and Documentation in Psychiatry" (AMDP) has developed the 2nd version of a new observer-rated scale for a quick and precise assessment of obsessive-compulsive symptoms. The first version of the scale comprised 20 items on the dimensions "description", "distress and impairment" and "emotion and cognition". The item pool of the 2. version was enlarged to 44 items to accomplish a differentiated assessment of obsessions and compulsions and to assess the associated passive avoidance behaviour. The results of an empirical study (n = 141) demonstrated excellent internal consistency (Cronbach's alpha = 0,93), a split-half reliability of 0,83 (Spearman-Brown), a test-retest reliability of r = 0,84, a high interrater-reliability, a high differential validity and good convergent validity with the Hamburger Zwangsinventar (HZI) and the SCL-90-R. The results are presented and their implications on the final steps of the development of the scale will be discussed.

The use of a symptom checklist (SCL-90-R) as an easy method to estimate the relapse risk after alcoholism detoxification.

We tested the use of some subscales of the psychiatric symptom checklist SCL-90-R in predicting relapse within a 1-year follow-up period after a combined detoxification- and abstinence-focused day patient psychotherapy program in 20 men and 13 women with alcohol dependence. Scores of the SCL-90-R subscales interpersonal sensitivity (p = 0.008), anxiety (p = 0.022), phobic anxiety (p = 0.019) and Global Severity Index (GSI; p = 0.040) on admission were higher in the subgroup with relapse within the first year after therapy. A decrease in depression (p = 0.004), anxiety (p = 0.006) and GSI (p = 0.006) scores during therapy was associated with a longer abstinence duration (shorter vs. longer than 24 weeks). Therefore we propose to further investigate the capacity of the SCL-90-R to identify subgroups at higher risk for relapse after detoxification and abstinence therapy in patients with alcohol dependence.

Lifetime-comorbidity of obsessive-compulsive disorder and subclinical obsessive-compulsive disorder in Northern Germany.

OBJECTIVE: Inspite of the worldwide relevance of obsessive-compulsive disorder (OCD), there is a substantial lack of data on comorbidity in OCD and subclinical OCD in the general population. METHODS: German versions of the DSM-IV adapted Composite International Diagnostic Interview were administered to a representative sample of 4075 persons aged 18-64 years, living in a northern German region. RESULTS: In both genders, high rates of comorbid depressive disorders were found in OCD and subclinical OCD, whereas somatoform pain disorder was only associated with OCD. In female subjects, OCD was additionally associated with social and specific phobias, alcohol, nicotine and sedative dependence, PTSD and atypical eating disorder. CONCLUSION: Due to low comorbidity rates, subclinical OCD seems to represent an independent syndrome not restricted to the presence of other axis-I diagnoses. Comorbidity patterns show a disposition to anxiety and to depressive disorders in OCD and subclinical OCD. A broad association with obsessive-compulsive spectrum disorders could not be confirmed in our general population sample.

[On the impact of disorder-specific versus general psychotherapy from the psychiatric viewpoint].

Concerning the discussion of disorder-specific versus general psychotherapy it has to be taken into consideration that institutional aspects in psychiatry as well as the definition of adequate outcome criteria are specific for different subgroups of patients. During the last 20 years most elaborated interventional approaches were developed for schizophrenic patients illustrating different topics of change.

Influence of the dopamine D2 receptor (DRD2) exon 8 genotype on efficacy of tiapride and clinical outcome of alcohol withdrawal.

We tested the hypothesis that allelic variants of the human dopamine D2 receptor E8 genotype are associated with (i) dopamine D2 antagonist tiapride dose in treatment of alcohol withdrawal (n = 50) and (ii) with anxiety and depression in patients during alcoholism detoxification therapy (admission n = 87; discharge n = 50). DRD2 E8 A/A genotype was associated with increased dose of tiapride during a 9-day detoxification therapy and with increased anxiety and depression scores on admission and 2 weeks later. The findings suggest a pharmacogenetic influence of DRD2 E8 genotype on tiapride efficacy in alcohol withdrawal. In an earlier report, DRD2 E8 A/A genotype was associated with reduced responsiveness to the dopamine D2 agonist apomorphine; however, it is not clear whether both findings share the same biological basis. Earlier findings concerning association of DRD2 E8 A/A with increased anxiety and depression are replicated for the first time.

Neurotrophic factor S100 beta in major depression.

Disturbances in the serotonergic system are considered to be implicated in the pathophysiology of depressive disorders. The possible role of the neurotrophic factor S100 beta, which is suspected to regulate regeneration of serotonergic synapses, has not been investigated in depressive disorders. The S100 beta concentration in the cerebrospinal fluid was measured in 11 patients with the current diagnosis of mild or moderate depressive episodes (DSM-IV) and in 11 matched control patients. Using the t test for paired samples, the presence of a depressive episode was significantly associated with an elevation of the cerebrospinal fluid concentration of S100 beta (t = 2.6, d.f. = 10, p = 0.024). Replications of this finding in severely depressed patients are necessary to confirm the association between neurotrophic factor S100 beta and depressive disorders.

[Reliability and validity of the German version of the Premorbid Adjustment Scale (PAS)].

The Premorbid Adjustment Scale (PAS) was developed by Cannon-Spoor et al. 1982 for research use and has gained importance internationally. This scale is designed to measure the extent of attaining developmental goals premorbidly. The German version is presented here, with first data on the reliability and validity of the scale. In a sample of schizophrenic and schizoaffective patients (n = 86) and healthy parents of the patients (n = 38), DSM-IV diagnosis was made and PAS and Positive and Negative Syndrome Scale (PANSS) data were taken along with information on the course of the disorder. Using Cronbachs alpha, the estimated reliability for the scale and subscales lay between 0.809 and 0.931. High PAS scores, representing poor premorbid adjustment, correlated significantly with low age of onset, high PANSS scores, insidious onset, long hospitalisation, and serious course of the disorder. The threshold of PAS scores between healthy and sick probands was at 0.23. Patients with scores > 0.53 appeared to have an unfavourable course. With test results > 0.23, an odds ratio of 27.9 was ascertained (95% CI 9.39-82.89). The findings presented correspond with those from previous reports in literature.

Prevalence, quality of life and psychosocial function in obsessive-compulsive disorder and subclinical obsessive-compulsive disorder in northern Germany.

BACKGROUND: Despite the worldwide relevance of obsessive-compulsive disorder (OCD) there are considerable differences in prevalence rates and gender ratios between the studies and a substantial lack of prevalence data on subclinical OCD. Moreover, data on quality of life and on psychosocial function of subjects with OCD and subclinical OCD in the general population are missing to date. METHODS: German versions of the DSM-IV adapted Composite International Diagnostic Interview were administered to a representative sample of 4075 persons aged 18-64 years living in a northern German region. Specific DSM-IV based criteria for subclinical OCD were used. RESULTS: The life-time prevalence rates for OCD and subclinical OCD were 0.5% and 2%, respectively. Twelve month prevalence rates were 0.39% and 1.6%, respectively. The gender female:male ratio was 5.7 in OCD and 1.2 in subclinical OCD. In various measures of psychosocial function and quality of life, OCD and subclinical OCD were significantly impaired. However, subclinical OCD subjects did not visit mental health professionals more often than controls. CONCLUSION: Due to different epidemiological characteristics subclinical OCD might represent a syndrome distinct from OCD which is also associated with significant impairments in personal and interpersonal functions and in quality of life.

Generalized anxiety disorder (ICD-10) in primary care from a cross-cultural perspective: a valid diagnostic entity?

OBJECTIVE: Generalized anxiety disorder (GAD) is a common psychiatric disorder. The nosological status of this diagnostic entity was critically discussed because of the very high rate of comorbidity with other psychiatric disorders, the assumed low degree of social disability associated with GAD in the absence of other disorders, and an ambigious definition. METHOD: We explored the frequency and associated social disability of GAD, and examined whether the ICD-10 definition of GAD is appropriate. The analysis was based on the WHO study on 'Psychological Problems in Primary Care' conducted in a standardized manner in 14 countries. RESULTS: We found GAD (total and without another psychiatric disorder) to be common in primary care in nearly all countries (mean 1-month prevalence rate, 7.9%), with about 25% of these cases presenting with GAD in the absence of any comorbid psychiatric disorder. GAD in general, as well as non-comorbid GAD, are associated with social disability which is as severe as that in chronic somatic diseases. CONCLUSION: It remains questionable whether the current ICD-10 diagnosis of GAD defining 6 months as a minimum duration and requiring at least four associated symptoms for diagnosis is the most appropriate option. Using this definition, a substantial proportion of psychosocially disabled subjects characterized by anxiety, tension and worrying remain undetected, and are possibly therefore not adequately treated.

Symptoms of eating disorders in obsessive-compulsive disorder.

OBJECTIVE: Despite some empirical evidence suggesting an association between primary OCD and eating disorder (ED) within the 'obsessive-compulsive spectrum', the relationship at a symptomatological level has not been investigated. METHOD: First, comparisons of Eating Disorder Inventory (EDI) scores between 61 patients with primary OCD and 288 control subjects were performed. Secondly, the associations between EDI subscores and Hamburg Obsessive-Compulsive Inventory (HZI) dimensions in OCD patients were investigated by multiple regression analyses, controlling for the impact of general psychopathology. RESULTS: The OCD patients showed significantly higher EDI-scores than controls. However, only distinct OCD symptom dimensions were significantly associated with the core symptoms of ED in females. CONCLUSION: Our results point to a differential gender and symptom-specific relationship between OCD and ED, calling into question a simple dimensional conceptualization of the 'obsessive-compulsive spectrum'.
