Personality subtyping and bulimia nervosa: psychopathological and genetic correlates.

BACKGROUND: There is empirical evidence suggesting that individuals with bulimia nervosa vary considerably in terms of psychiatric co-morbidity and personality functioning. In this study, latent profile analysis was used to attempt to identify clusters of bulimic subjects based on psychiatric co-morbidity and personality. METHOD: A total of 178 women with bulimia nervosa or a subclinical variant of bulimia nervosa completed a series of self-report inventories of co-morbid psychopathology and personality, and also provided a buccal smear sample for genetic analyses. RESULTS: Three clusters of bulimic women were identified: an affective-perfectionistic cluster, an impulsive cluster, and a low co-morbid psychopathology cluster. The clusters showed expected differences on external validation tests with both personality and eating-disorder measures. The impulsive cluster showed the highest elevations on dissocial behavior and the lowest scores on compulsivity, while the affective-perfectionistic cluster showed the highest levels of eating-disorder symptoms. The clusters did not differ on genetic variations of the serotonin transporter gene. CONCLUSIONS: This study corroborates previous findings suggesting that the bulimia nervosa diagnostic category is comprised of three classes of individuals based on co-morbid psychopathology and personality. These differences may have significant etiological and treatment implications.

A family study of alcohol dependence: coaggregation of multiple disorders in relatives of alcohol-dependent probands.

BACKGROUND: Alcohol dependence tends to aggregate within families. We analyzed data from the family collection of the Collaborative Study on the Genetics of Alcoholism to quantify familial aggregation using several different criterion sets. We also assessed the aggregation of other psychiatric disorders in the same sample to identify areas of possible shared genetic vulnerability. DESIGN: Age-corrected lifetime morbid risk was estimated in adult first-degree relatives of affected probands and control subjects for selected disorders. Diagnostic data were gathered by semistructured interview (the Semi-Structured Assessment for the Genetics of Alcoholism), family history, and medical records. Rates of illness were corrected by validating interview and family history reports against senior clinicians' all sources best estimate diagnoses. Sex, ethnicity, comorbidity, cohort effects, and site of ascertainment were also taken into account. RESULTS: Including data from 8296 relatives of alcoholic probands and 1654 controls, we report lifetime risk rates of 28.8% and 14.4% for DSM-IV alcohol dependence in relatives of probands and controls, respectively; respective rates were 37.0% and 20.5% for the less stringent DSM-III-R alcohol dependence, 20.9% and 9.7% for any DSM-III-R diagnosis of nonalcohol nonnicotine substance dependence, and 8.1% and 5.2% for antisocial personality disorder. Rates of specific substance dependence were markedly increased in relatives of alcohol-dependent probands for cocaine, marijuana, opiates, sedatives, stimulants, and tobacco. Aggregation was also seen for panic disorder, obsessive-compulsive disorder, posttraumatic stress disorder, and major depression. CONCLUSIONS: The risk of alcohol dependence in relatives of probands compared with controls is increased about 2-fold. The aggregation of antisocial personality disorder, drug dependence, anxiety disorders, and mood disorders suggests common mechanisms for these disorders and alcohol dependence within some families. These data suggest new phenotypes for molecular genetic studies and alternative strategies for studying the heterogeneity of alcohol dependence.

[Relations between mood disorders and personality. Recent data].

In the field of studies of links between mood disorders and personality, the need to study only completely remitted patients has been demonstrated recently. Indeed, the clinically depressed state strongly influences the assessment of some personality traits in a more pathological direction (for instance for emotional stability, extraversion, interpersonal dependency, ego strength). The studies concerning unipolar depression have been mainly made according to two methodological approaches which results are relatively consistent. The first one uses batteries of standard self-report personality inventories such as the Hirschfeld and Klerman battery which includes the Guilford-Zimmerman Temperament Survey, the Interpersonal Dependency Inventory, the shortened version of the Lazare-Klerman-Armor Personality Inventory and two subscales of the MMPI. This approach shows that compared to normal population, recovered depressive, have less emotional strength more interpersonal dependency and a more introverted personality. The second approach uses diagnostic criteria of personality disorders according to DSM III. The clinical evaluation can be performed with the help of the Structured Interview for DSM III Personality Disorders (SIDP) or with of the help the Millon Clinical Multiaxial Inventory (MCMI), a self rated questionnaire. The most frequent personality disorder among recovered unipolar patients is dependent personality, followed by the avoidant and histrionic personalities and lastly the schizoïd, schizotypal, borderline, compulsive and passive-aggressive personalities. But the interpretation of all these results must be cautious given that a recent study dealing with premorbid personality invites one to consider that not only depression influences personality assessment during illness, but also that depression may result in personality change after recovery. Few studies are available concerning bipolar patients.(ABSTRACT TRUNCATED AT 250 WORDS)

The Shatin community mental health survey in Hong Kong. II. Major findings.

A large-scale community survey in Shatin, Hong Kong, is presented with a modified two-phase design using flagged and nonflagged subsamples. A modified Self-Reporting Questionnaire and the Diagnostic Interview Schedule (version III) were used as the screening and diagnostic instruments, respectively. Lifetime rates for 19 Diagnostic Interview Schedule/DSM-III diagnoses are presented. The most common diagnoses in Shatin were tobacco dependence, generalized anxiety disorder, alcohol abuse and/or dependence, all phobias, and dysthymic disorder. The male-predominant disorders were tobacco dependence, alcohol abuse/dependence, pathological gambling, and antisocial personality. The female-predominant disorders were generalized anxiety disorder, all phobias, dysthymic disorder, major depressive disorder, obsessive-compulsive disorder, and bereavement.

Bipolar disorder in adult patients with Tourette's syndrome: a clinical study.

BACKGROUND: Although recent clinical and epidemiological studies indicate that Tourette's syndrome (TS) is associated with a higher than expected rate of bipolar disorder (BPD), the clinical characteristics of BPD in patients with TS have not been widely investigated. METHODS: Thirty adult TS patients with comorbid BPD were selected from a consecutive series of 90 referred TS patients and examined using structured psychiatric rating scales. RESULTS: The full clinical spectrum of BPD was found, including bipolar I disorder, schizoaffective bipolar disorder, bipolar II disorder, and cyclothymic disorder. Atypical vegetative depressive symptoms, rapid cycling patterns, and seasonal patterns of recurrence were also documented. In the present clinical sample, BPD mainly occurred in patients with mild tic symptoms and was invariably associated with a high lifetime prevalence of general psychopathology, including generalized anxiety disorder, obsessive-compulsive disorder, panic, phobias, eating disorders, self-injurious behavior, attention-deficit hyperactivity disorder, impulse control disorders, and personality disorders. CONCLUSIONS: The results of this clinical study indicate that BPD and nonaffective psychopathology may be prominent comorbid disorders in a subpopulation of patients with TS.

Kleptomania: comorbid psychiatric diagnosis in patients and their families.

OBJECTIVES: Kleptomania, defined by DSM-IV as the inability to resist the impulse to steal objects which are not needed for personal use or for their monetary value, may reflect a form of obsessive-compulsive spectrum disorder and/or affective spectrum disorder. METHODS: Twenty-one kleptomanic patients and 57 first-degree relatives completed a semistructured DSM-IV-based interview and questionnaires. Questionnaires are: the HDRS-17 (the Hamilton Rating Scale for Depression), the HARS (Hamilton Rating Scale for Anxiety), the Y-BOCS (Yale-Brown Obsessive Compulsive Scale), the YMRS (Young Mania Rating Scale). The two groups were compared to demographically matched normal controls (n = 64). RESULTS: We found a high prevalence of affective and anxiety disorders in our sample of kleptomanic patients and their first-degree relatives. In addition, the scores on the HDRS, HARS, and Y-BOCS were significantly higher in the study group than in the control group. CONCLUSIONS: Our finding of a high prevalence of psychiatric comorbidity in kleptomanic patients could lead to the development of new treatment strategies for this disorder. Furthermore, the pattern of psychiatric disorders seen in the first-degree relatives can lead to new insights about the nosology and etiopathology of kleptomania.

Nursing management of psychotropic drug reactions.

The prevalence of psychiatric disorders in primary care is approximately 22%. These disorders include major depressive disorder, panic disorder, alcohol dependence/abuse, generalized anxiety disorder, and obsessive-compulsive disorder. The deinstitutionalization movement has placed an increasing number of severe and persistently mentally ill persons, defined as those with schizophrenia, psychosis, bipolar, and unipolar disorders, into the community. Nurses working in acute primary care, home health, and long-term medical settings can expect to encounter patients who are using prescriptive psychotropic medications; these patients may be experiencing adverse reactions. This article discusses antidepressants, mood stabilizers, antipsychotics, anxiolytics and specific medications for children and the elderly, and their adverse effects as a way of assisting nurses in making appropriate patient assessments.

Self-injurious behavior and serotonin in Prader-Willi syndrome.

Low central nervous system (CNS) serotonin levels have been associated with impulsive, aggressive and self-injurious behavior (SIB). Persons with Prader-Willi Syndrome (PWS) often engage in self-injury by severe compulsive skin picking and gouging and often manifest compulsive eating, hoarding, and explosive outbursts. Some of the compulsive behaviors seen in patients with obsessive-compulsive disorder (OCD) bear similarity to behaviors associated with PWS: Skin picking, trichotillomania, and onychophagia (nail biting). There is abundant evidence that selective serotonin reuptake inhibitors (SSRIs) are effective in treating OCD. Three cases are described in which persons with PWS responded favorably to SSRI treatment. Two persons showed a significant decrease in skin picking. The third case showed a significant decrease in hoarding and explosive outbursts. Strategies are discussed for investigating the possibility of a shared neurochemical basis for the self-injurious, aggressive, and compulsive behaviors in persons with PWS. PWS may provide a relatively homogenous model for the study of skin picking and explosive outbursts among other populations.

Current issues in adolescent psychiatry.

Adolescent psychiatry as a body of knowledge has shown encouraging growth in recent years, as research findings from general psychiatry have been added to new data on adolescent psychological and physical development. The author reviews recent findings on selected topics in adolescent psychopathology, including adaptive disorders, obsessive-compulsive disorders, phobias, attention deficit disorders, depression, manic-depressive illness, suicidal impulses, schizophrenia, anorexia nervosa, and borderline states. He also outlines findings on normal adolescent development and discusses the problems of diagnosing children and adolescents with psychological problems. Studies in anxiety, attention deficit, and conduct disorders, he says, are yielding important new findings by combining biological and psychological insights.

Dysmorphic concern symptoms and personality disorders: a clinical investigation in patients seeking cosmetic surgery.

Body dysmorphic disorder (BDD) is a somatoform disorder characterized by an excessive concern with an imagined or slight defect in appearance. BDD has been particularly studied in cosmetic surgery settings. The object of the present study is to investigate the relationship between personality disorders and dysmorphic symptoms in a group of 66 patients seeking cosmetic surgery. Assessment instruments included the following: a semistructured interview for demographic and clinical characteristics; the Structured Clinical Interview for DSM-IV, the Hamilton Depression and Anxiety Rating Scales, and the Body Dysmorphic Disorder Yale - Brown Obsessive--Compulsive Scale (BDD - YBOCS). A multiple regression analysis was performed using the BDD - YBOCS score as a continuous dependent variable. The severity of dysmorphic symptoms (BDD - YBOCS score) was significantly related to two factors: the number of diagnostic criteria for schizotypal and paranoid personality disorders. The results suggest that the presence of a psychopathological reaction to imagined defects in appearance in subjects pursuing a surgical correction is associated with the severity of schizotypal and paranoid personality disorders. Preoperative assessment could help to define the clinical profile of patients in cosmetic surgery settings.

The role of personality disorders on drug dependence treatment outcomes following inpatient detoxification.

AIMS: The present 6 month follow-up study was conducted to investigate the possible influence of comorbid personality disorders on drug treatment, as well as associated psychopathology and HIV-related risk behaviors outcomes. SUBJECTS AND METHODS: Data were collected initially from a consecutive sample of 74 patients with a diagnosis of opiate abuse or dependence, admitted for inpatient detoxification. RESULT: During intake, 80.9% of patients reported at least one HIV-related risk behavior in the previous 6 months. Not using condoms during sexual intercourse was the most common and the only risk behavior that showed a statistically significant reduction over the follow-up period. A total of 58.1% of subjects had at least one personality disorder (PD). Borderline PD was the most prevalent. However, antisocial PD was the only PD that influenced substance use outcomes. The presence of this diagnosis increased the chance of worse opiate use outcomes, but decreased likelihood of not using condoms. Patients with low obsessive-compulsive PD dimensional scores showed a significant increase in the number of risk behaviors. However, these influences were only seen at the 3-month follow-up assessment. CONCLUSIONS: These results suggest that personality disorders need to be considered when planning effective interventions for opiate dependent individuals and when preparing and evaluating HIV risk-reduction interventions, particularly for the more severe substance dependent patients.

A controlled study of Tourette syndrome. IV. Obsessions, compulsions, and schizoid behaviors.

To determine the frequency of obsessive, compulsive, and schizoid behaviors in Tourette syndrome (TS), we prospectively questioned 246 patients with TS, 17 with attention-deficit disorder (ADD), 15 with ADD due to a TS gene, and 47 random controls. The comparative frequency of obsessive, compulsive, and repetitive behaviors--such as obsessive unpleasant thoughts, obsessive silly thoughts, echolalia, palilalia, touching things excessively, touching things a specific number of times, touching others excessively, sexual touching, biting or hurting oneself, head banging, rocking, mimicking others, counting things, and occasional or frequent public exhibitionism--were significantly more common in TS patients than in controls. The frequency of each of these was much higher for grade 3 (severe) TS. Most of these behaviors also occurred significantly more often in individuals with ADD or in individuals with ADD secondary to TS (ADD 2(0) TS). When these features were combined into an obsessive-compulsive score, 45.4% of TS patients had a score of 4-15, whereas 8.5% of controls had a score of 4 or 5. These results indicate that obsessive-compulsive behaviors are an integral part of the expression of the TS gene and can be inherited as an autosomal dominant trait. Schizoid symptoms, such as thinking that people were watching them or plotting against them, were significantly more common in TS patients than in controls. Auditory hallucinations of hearing voices were present in 14.6% of TS patients, compared with 2.1% of controls (P = .02). These symptoms were absent in ADD patients but present in ADD 2(0) TS patients. These voices were often blamed for telling them to do bad things and were frequently identified with the devil. None of the controls had a total schizoid behavior score greater than 3, whereas 10.9% of the TS patients had scores of 4-10 (P = .02). This frequency increased to 20.6% in the grade 3 TS patients. These quantitative results confirm our clinical impression that some TS patients have paranoid ideations, often feel that people are out to get them, and hear voices.

Sweets, chocolate, and atypical depressive traits.

An original questionnaire, the Foods and Moods Inventory (FMI) was used to investigate appetite for sweets and chocolate and its relationship to dysphoric mood. The FMI was administered to a group of subjects with an identified interest in chocolate (chocolate group, N = 73), a comparison sample (comparison group, N = 172), and a sample of former alcoholics (N = 22). Those who reported "self-medicating" with sweets or chocolate were more likely to have personality traits associated with hysteroid dysphoria, an atypical depressive syndrome. In addition, the tendency to eat compulsively, in general, and appetite for sweets and chocolate, in particular, were significantly greater among women.

[Clinical characteristics and typology of the obsessive-compulsive disorder in slowly-progressing recurrent schizophrenia with the onset in childhood and adolescence].

As many as 56 patients suffering from slow-progredient attack-like schizophrenia running its course with the predominance of obsessions in the clinical picture were examined and followed up for 3 to 5 years. At the moment of the examination the patients' age ranged from 8 to 15 years. It has been established that during slow-progredient attack-like schizophrenia in children and adolescents, obsessions occur in the structure of "large" obsessive syndromes characterized by polymorphism of psychopathological disorders and always including remarkable affective symptomatology. Six types of obsessive conditions were distinguished, each of which was marked by a definite stereotype of the disease natural history and correlated with the degree of the process progress. Among the types of obsessive conditions described, depressive ones with obsessions (three types) led on the whole to less pronounced alterations of the personality than obsessive-anxious ones, particularly anxious-hypochondriac attacks after the completion of which there formed relatively more profound personality changes.

Substance dependence and other psychiatric disorders among drug dependent subjects: race and gender correlates.

Persons in drug treatment with drug dependence were interviewed with the NIMH Diagnostic Interview Schedule to ascertain DSM-III-R disorders. Lifetime prevalence rates were 64% for alcohol dependence, 44% for antisocial personality disorder (ASPD), 39% for phobic disorders, 24% for major depression, 12% for dysthymia, 10% for generalized anxiety disorder, 3% for panic disorder, 3% for mania, 3% for obsessive compulsive disorder, 2% for bulimia, 1% for schizophrenia, and 1% for anorexia. When stratified by race and age, significant main effects were seen, but there were no significant interactions except in "any non-substance disorder" and in the mean number of non-substance use disorders. Caucasians had a higher mean number of drug dependence disorders and higher overall rates of "any other" disorder than African-Americans, and Caucasians and males had higher mean numbers of non-substance use disorders than African-Americans and females, respectively. This was related to rates of alcohol, cannabis, and hallucinogen dependence, and ASPD rates that were higher among men than women and higher among Caucasian respondents than African-American for alcohol, cannabis, hallucinogen, opiate and sedative dependence, major depression, dysthymia, and generalized anxiety disorder. In contrast, women had higher rates than men of amphetamine dependence, phobic disorder, major depression, dysthymia, panic disorder, obsessive compulsive disorder, and mania. African-Americans had higher rates than Caucasians of amphetamine, cocaine, and phencyclidine dependence, but for no comorbid disorders were the rates higher among African-Americans than Caucasians. The differences according to gender in rates of disorders among substance dependent persons are consistent with the results of general population surveys, but the differences in rates according to race are in contrast to these same community surveys. Limitations in the utility of the concept of race as a valid category diminish the generalizability of the findings; however, one possible explanation is differential treatment seeking in African-American and Caucasian populations that would result in the differences seen.

Neural responses of OCD patients towards disorder-relevant, generally disgust-inducing and fear-inducing pictures.

This functional magnetic resonance imaging study investigated the disgust- and fear-reactivity of patients suffering from obsessive-compulsive disorder (OCD). Ten OCD patients were scanned while viewing blocks of pictures showing OCD triggers from their personal environment and OCD-irrelevant disgust-inducing, fear-inducing and neutral scenes. Afterwards, the patients rated the intensity of the induced disgust, fear and OCD symptoms. The responses were compared with those of 10 healthy control subjects. The disorder-relevant pictures provoked intense OCD symptoms in the clinical group associated with increased activation in the bilateral prefrontal cortex, the left insula, the right supramarginal gyrus, the left caudate nucleus and the right thalamus. The patients gave higher disgust and fear ratings than the controls for all aversive picture categories. Neural responses towards the disorder-irrelevant disgusting and fear-inducing material included more pronounced insula activation in patients than controls. Summarizing, photos of individual OCD-triggers are an effective means of symptom provocation and activation of the fronto-striato-thalamo-parietal network. The increased insular reactivity of OCD patients during all aversive picture conditions might mirror their susceptibility to experience negative somatic states.
