[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.

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'.

[Axis I "illness experience and treatment preconditions" of operational psychodynamic diagnosis (OPD). Experiences in clinical practice].

In a selective survey, results on psychometric properties and aspects of application of the axis I, "illness experience and treatment preconditions" of the Operational Psychodynamic Diagnoses (OPD) are described. Following remarks on the role of defense and coping theories in the conceptualisation of the axis, its structure and contents are outlined. After a brief summary of findings on its interrater reliability, several aspects of validity are discussed. Results on discriminative validity show that axis I items are useful in the statistical discrimination of subsamples differing in age, clinical diagnoses, and diagnostic setting (psychotherapy outpatient vs. psychosomatic consultation-liasion services). The contribution of axis I items to prediction of treatment outcomes, moreover, reveals high degree of predictive or treatment validity. After an integrative discussion of these findings, implications of patient personality and coping behaviour for axis I ratings are highlighted as important objectives for future OPD research.

[The operational diagnostic approach of the borderline personality disorder. An interview of psychiatrists and psychologists according to their concept of the syndrome].

Despite the diagnostic criteria of the ICD-10 and DSM-IV, the term borderline has been used in a non-specific way for a long time. For our investigation we constructed a questionnaire, which contained the ICD-10 diagnostic criteria for the borderline personality disorder (BPD), plus the criteria for the other personality disorders and for the schizotype disorder. The two additional criteria for the BPD used by the DSM-IV were added. 800 psychiatrists and psychologists were asked to mark all criteria, which they thought were typical for the BPD. By using the operational diagnostic approach for ICD-10 and DSM-IV a disorder was diagnosed from each of the 162 received questionnaires based on the marked criteria. 92.0% of the questionnaires contained marked criteria for the diagnosis of the BPD by ICD-10 and 96.3% by DSM-IV. In addition each questionnaire contained up to eight other diagnosis. This is a sign for the difficulty to separate the BPD from other personality disorders or the schizotype disorder by using operationalized criteria. Looking at the lack of specificity of the operational diagnostic systems for personality disorders, e.g. for the BPD which has been discussed by many authors for years, modification of the diagnostic systems should be considered.

Dissociative experiences and psychopathology in conversion disorders.

The concepts of dissociation and conversion are historically linked with the first psychodynamic ideas on hysteria. However, the abolition of "hysterical neurosis" from current nosology has led to independent developments of these theoretical models. Recent studies found a high degree of somatization in dissociative disorders. However, little is known about dissociation in conversion disorders. We assessed 72 patients with conversion disorders for their dissociative and general psychopathology using the German version of the Dissociative Experience Scale (DES) and the Symptom Check List (SCL-90-R). They were compared with a control group of 96 psychiatric patients suffering from various neurotic disorders, who were matched for gender and age. Dissociative symptoms were significantly more frequent in conversion disorder patients than in controls. There were no differences in the SCL-90-R scores between the two groups. Our findings support the theory of similar psychological processes underlying conversion and dissociative disorders despite their descriptive differences.

This review summarizes from biological research in obsessive-compulsive disorder. In particular, functional brain imaging studies investigating the effects of Symptom provocation, of behavioral and pharmacological treatment on brain activity and findings from neurochemical studies are presented with regard to the serotonergic System. We discuss a neurobiological model integrating the findings from brain imaging, functional anatomy and behavioral concepts which favors a functional imbalance within the orbitofrontal - basal ganglia - thalamus ciruit and focus on hypothesis for further research.

Though the use of elaborated and standardized behavioral therapy strategies has been successful in treatment evaluation and in areas of neurobiological research, numerous psychoanalytically orientated therapists will exhibit fear and avoidance behavior while facing terms like "standardization", "treatment evaluation studies" and "neurobiology". In our comment, we aim to initiate a successful therapeutic process by intensified reality testing and repeated exposure therapy.

[Organization of telephone counseling for psychosocial emergencies. An evaluation after 12 months].

OBJECTIVE: To improve the community-based health care in the area of Bonn a telephone consulting service and a mobile crisis intervention service have been established during a two year pilot project. The regional needs and structural demands have been assessed. RESULTS: During the first 12 months the number of calls increased from 15 in November 1996 to 76 in October 1997. In all, 432 calls were received. Most calls lasted from 10 to 30 minutes. 89% of the callers were female, 77% were in the age range between 30 and 45 years. Two-thirds of the callers had prior psychiatric treatments. Most callers suffered from loneliness and deficient coping strategies. CONCLUSION: The prove regional demands have led to a continuation of the project and an extension of the mobile crisis intervention service.

Reliability of interview information in a family study in the elderly.

The aim of the present study was to evaluate the combined test-retest and interrater reliability of different psychiatric lifetime diagnoses yielded in the course of a family study in elderly patients and controls. The following interviews and questionnaires were used in combination: the Composite International Diagnostic Interview (CIDI), the Structured Interview for the Diagnosis of Dementia of the Alzheimer Type, Multi-infarct Dementia and Dementias of Other Aetiology (SI-DAM), the General Health Questionnaire (GHQ-12) and questionnaires for neurasthenia and recurrent brief depression (RBD). Depressive and dementia disorders can be diagnosed with good reliability in a family study setting with the use of these instruments. The diagnoses of phobic disorders, neurasthenia, RBD, subthreshold RBD and psychiatric caseness as indicated by GHQ-12 scores were less reliable in this setting and are therefore less suitable for use in family studies.
