Comorbid personality disorders and substance use disorders of mentally ill homicide offenders: a structured clinical study on dual and triple diagnoses

Comorbid substance use disorders (SUDs) increase the risk of homicide by persons with major mental disorders (MMDs). However, there are no published data from clinical interviews or lifetime objective documents on the prevalence of lifetime personality disorder (PD) or SUD among a comprehensive sample of mentally ill homicide offenders. Therefore, a nationally representative sample of men with MMD (n = 90) who had committed or attempted homicide was assessed using the research version of the Structured Clinical Interview for DSM-IV Axis I and Axis II Disorders. Lifetime documents, records, and questionnaires from persons who knew the subjects since childhood were used. Seventy-eight percent of the mentally ill homicide offenders were diagnosed with schizophrenia, 17 percent with schizoaffective disorder, and 5 percent with other psychosis. A lifetime SUD was detected in 74 percent and alcohol use disorder in 72 percent. PD accounted for 51 percent, in 47 percent as antisocial personality disorder (APD). All subjects diagnosed with PD had SUD. Only 25 percent of the subjects had neither SUD nor PD. Among persons with dual diagnoses (MMD and SUD), about two-thirds had PD or APD. These results indicated that there were two-thirds major diagnostic categories of psychotic homicide offenders: about one-half had triple diagnosis (APD + SUD + MMD), one-quarter had "pure" dual diagnosis (SUD + MMD), and one-quarter had "pure" MMD. The fourth possible category, "APD + MMD but no SUD," was not found. The prevention of severe violence by persons with MMD necessitates effective treatments for those with dual diagnosis who also have a history of APD.     

Characteristics associated with use of homeopathic drugs for psychiatric symptoms in the general population

ObjectiveTo explore which patient characteristics are associated in naturalistic conditions with the lifetime use of homeopathic treatment for psychiatric symptoms.MethodLifetime use of psychotropic treatment was explored in a sample of 36,785 persons, participating in the Mental Health Survey in the General Population. Characteristics associated with use of homeopathic treatments, associated or not with conventional psychotropic drugs, were explored using multivariate analyses.ResultsUse of homeopathic treatment for psychiatric symptoms was reported by 1.3% of persons. Younger age, female gender and high educational level were associated with use of homeopathy. Half of homeopathy users presented at least one Mini International Neuropsychiatric Interview (MINI) diagnosis, most frequently anxiety disorders. Their diagnostic profile was similar to that of persons reporting use of anxiolytics or hypnotics. Compared to persons with no lifetime use of psychotropic drugs, persons using homeopathy were more likely to present with a diagnosis of mood disorder or anxiety disorder. Compared to those using conventional psychotropic drugs, they presented less frequently with psychiatric disorders, with the exception of anxiety disorders.ConclusionHomeopathic treatment for psychiatric symptoms appears to be used mainly to reduce anxiety symptoms in the general population.     

Trauma and posttraumatic stress disorder in treatment-resistant obsessive-compulsive disorder

Prior research has indicated a seemingly unique relation between obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD) that appears to relate to negative treatment outcome for OCD. However, to date, the prevalence of trauma and PTSD in individuals seeking treatment for OCD is unclear. To begin to address this gap, this study assessed history of traumatic experiences and current PTSD in individuals seeking treatment for treatment-resistant OCD. Trauma predictors of PTSD severity also were examined in this sample. Participants included 104 individuals diagnosed with treatment-resistant OCD who sought treatment over the course of 1 year from OCD specialty treatment facilities. Data were collected via naturalistic retrospective chart reviews of pre-treatment clinical intake files. Findings revealed that 82% of participants reported a history of trauma. Over 39% of the overall sample met criteria for PTSD, whereas almost 50% of individuals with a trauma history met criteria for PTSD. Interpersonal traumas and greater frequency of traumas were most predictive of PTSD severity, and individuals diagnosed with OCD and additional major depressive disorder (MDD) or borderline personality disorder (BPD) appeared at particular risk for a comorbid PTSD diagnosis. PTSD may be relatively common in individuals diagnosed with treatment-resistant OCD; and interpersonal traumas, MDD, and BPD may play a relatively strong predictive role in PTSD diagnosis and severity in such OCD patients.     

The use of psychiatric facilities by depressives: results of the Upper Bavarian Study

Utilization of psychiatric facilities by noninstitutionalized persons aged 20 years and older, identified as "depressive cases", was examined. Data were based on the representative community sample of the Upper Bavarian follow-up field study with an original sample size of 1668 people. In the 5-year follow-up 1384 (83%) subjects were interviewed, while 80 subjects (4.8%) had died. The 5-year prevalence of depressive disorders, according to the definition used, was 10.3%. We analyzed which people with depressive disorders sought help from mental health professionals according to type of depressive disorder, sociodemographic data, psychosocial factors and course of disorder. The psychiatric treatment rate (in- or outpatient) was 23.9% of the depressive cases. The majority of treated persons were outpatients. Patients with the diagnosis of endogenous depression were most likely to have received psychiatric treatment. Limitation in the ability to work due to depression was the most important psychosocial factor influencing help-seeking behavior. The highest consultation rate in psychiatric facilities was obtained from the depressives who had grown up without their parents.     

Prevalence of mental disorders in Europe: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD) project

OBJECTIVE: To describe the 12-month and lifetime prevalence rates of mood, anxiety and alcohol disorders in six European countries. METHOD: A representative random sample of non-institutionalized inhabitants from Belgium, France, Germany, Italy, the Netherlands and Spain aged 18 or older (n = 21425) were interviewed between January 2001 and August 2003. DSM-IV disorders were assessed by lay interviewers using a revised version of the Composite International Diagnostic Interview (WMH-CIDI). RESULTS: Fourteen per cent reported a lifetime history of any mood disorder, 13.6% any anxiety disorder and 5.2% a lifetime history of any alcohol disorder. More than 6% reported any anxiety disorder, 4.2% any mood disorder, and 1.0% any alcohol disorder in the last year. Major depression and specific phobia were the most common single mental disorders. Women were twice as likely to suffer 12-month mood and anxiety disorders as men, while men were more likely to suffer alcohol abuse disorders. CONCLUSION: ESEMeD is the first study to highlight the magnitude of mental disorders in the six European countries studied. Mental disorders were frequent, more common in female, unemployed, disabled persons, or persons who were never married or previously married. Younger persons were also more likely to have mental disorders, indicating an early age of onset for mood, anxiety and alcohol disorders.     

The Netherlands Study of Depression and Anxiety (NESDA): rationale, objectives and methods

The Netherlands Study of Depression and Anxiety (NESDA) is a multi-site naturalistic cohort study to: (1) describe the long-term course and consequences of depressive and anxiety disorders, and (2) to integrate biological and psychosocial research paradigms within an epidemiological approach in order to examine (interaction between) predictors of the long-term course and consequences. Its design is an eight-year longitudinal cohort study among 2981 participants aged 18 through 65 years. The sample consists of 1701 persons with a current (six-month recency) diagnosis of depression and/or anxiety disorder, 907 persons with life-time diagnoses or at risk because of a family history or subthreshold depressive or anxiety symptoms, and 373 healthy controls. Recruitment took place in the general population, in general practices (through a three-stage screening procedure), and in mental health organizations in order to recruit persons reflecting various settings and developmental stages of psychopathology. During a four-hour baseline assessment including written questionnaires, interviews, a medical examination, a cognitive computer task and collection of blood and saliva samples, extensive information was gathered about key (mental) health outcomes and demographic, psychosocial, clinical, biological and genetic determinants. Detailed assessments will be repeated after one, two, four and eight years of follow-up. The findings of NESDA are expected to provide more detailed insight into (predictors of) the long-term course of depressive and anxiety disorders in adults. Besides its scientific relevance, this may contribute to more effective prevention and treatment of depressive and anxiety disorders.

Factors associated with high use of public mental health services by persons with borderline personality disorder

OBJECTIVE: The research presented here was a pilot study to identify clinical factors associated with high use (as opposed to lower use) of inpatient psychiatric services by persons with borderline personality disorder. METHODS: The initial sample was a random sample of English- and Spanish-speaking persons aged 18 to 60 years who had received at least one outpatient mental health service in the previous 90-day period and were enrolled in one of the participating mental health centers in King County, Washington. A random sample of persons who met selection criteria was randomly drawn; persons with high levels of use were oversampled to ensure adequate representation. Twenty-nine participants met full criteria for borderline personality disorder on the Personality Disorders Examination structured interview and completed all measures. Fifteen (52 percent) of these had a high level of use of inpatient services, and 14 did not. RESULTS: High use of inpatient psychiatric services was predicted by a history of parasuicide in the previous two years but not by the number or severity of parasuicides; by the presence and number of anxiety disorders but not by depression or psychotic or substance use disorders; and by poorer cognitive functioning. Life stressors, global functioning, and health service variables did not differentiate patients with high levels of service use from other patients with borderline personality disorder. CONCLUSIONS: Further research should explore these predictors of service use to determine whether they are replicated in larger samples, and treatments that target these variables should be evaluated.     

Differing correlates for suicide attempts among patients with schizophrenia or schizoaffective disorder in India and USA

BACKGROUND: Suicide is one of the most common causes of death among persons with schizophrenia. Differing risk factors have been identified in published studies. The differences may have arisen because a uniform set of variables was not analyzed. Alternatively, the nature and effect of risk factors may vary in different settings. To test these possibilities, we investigated the same set of variables in two independent cross-national samples ascertained using identical protocols. METHODS: Patients with schizophrenia or schizoaffective disorder (DSM IV criteria) were recruited in India (n=460) and the USA (n=424). RESULTS: Consistent with earlier publications, a diagnosis of schizoaffective disorder, history of depression, pattern of symptoms and educational status were significantly associated with suicide attempts in the US sample. None of these variables were significantly associated in the Indian sample. CONCLUSIONS: The impact of known risk factors for suicide attempts among patients with schizophrenia differs across ethnic groups.     

DUAL DIAGNOSIS IN ELDERS DISCHARGED FROM A PSYCHIATRIC HOSPITAL

Recent evidence indicates persons 60 years and over experience significant alcohol and substance abuse problems. Since a combination of alcoholism and depression is likely to increase the relative rsk of suicide, it is important to examine the prevalence of dual diagnosis in older adults. The purpose of this study is to examine the prevalence and correlates of dual diagnosis in older psychiatric inpatient populations and compare our results with findings from studies of younger hospitalized dually diagnosed patients. A retrospective chart audit was performed on 101 elders who were discharged from three psychiatric hospitals. Clinical variables that were examined included length of hospital stay, psychiatric and medical diagnoses, medications and history of suicidal ideation or intent. The leading psychiatric disorder diagnosis for our sample of hospitalized psychiatric elders was depression. Over one-third (37.6%) had a substance abuse disorder in addition to a psychiatric disorder, and almost three-fourths (71%) of this ‘dual diagnosis’ group abused alcohol and 29% abused both alcohol and other substances. In addition, significantly more elders in the ‘dual diagnosis’ group (17.7%) than in the group with only a mental disorder diagnosis (3.3%) made a suicide attempt prior to admission to the hospital. Because affective disorders in conjunction with alcohol abuse are the most frequently found disorders in completed suicides, our findings have important relevance for the advocating of routine use of diagnostic assessment and screening for both substance abuse and mental disorders in this population. © 1997 by John Wiley & Sons, Ltd.     

Clinical correlates of recurrent major depression in obsessive-compulsive disorder

Major depressive disorder is the most frequent comorbid condition in obsessive-compulsive disorder (OCD). This study investigated factors associated with the development of recurrent major depressive disorder (RDD) in patients with OCD. Eighty OCD cases and 73 control probands were examined by psychiatrists or clinical psychologists using the Schedule for Affective Disorders and Schizophrenia-Lifetime Anxiety (SADS-LA). Two experienced psychiatrists independently reviewed all clinical materials and made final consensus diagnoses using DSM-IV criteria. Family history of OCD and RDD, additional comorbid disorders, OCD symptoms and illness severity were compared between persons with OCD alone (n = 21) and OCD with RDD (n = 41). Compared to OCD probands without RDD, OCD probands with RDD had earlier age at first diagnosis, more severe obsessive-compulsive symptoms, and were more likely to have a family history of RDD. Social phobia, separation anxiety disorder, and body dysmorphic disorder occurred more frequently in the comorbid group. In a multiple logistic regression model, only early age of OCD diagnosis was significantly associated with RDD. Early age at onset of OCD increases the risk of depressive disorder in individuals with OCD.     

African-American participants in a bipolar disorder registry: clinical and treatment characteristics

OBJECTIVES: The goal of this paper was to compare clinical characteristics and treatment history of African-American and Caucasian participants in a bipolar disorder registry. METHODS: The Western Pennsylvania Bipolar Disorder Registry used several recruitment methods to reach individuals self-identified as having bipolar disorder. Individuals who contacted and joined the registry completed an interviewer-administered questionnaire on clinical characteristics and treatment history. A sample of 2,718 registry participants was analyzed in order to compare these characteristics and history by race. RESULTS: African-Americans in the registry reported a greater number of inpatient hospitalizations (9.8 versus 4.4) than Caucasians, as well as a higher suicide attempt rate (64% versus 49%). African-American participants were more likely to report a family member with schizophrenia. With respect to psychotropic medication, African-Americans were less likely to report taking antimanic medication or benzodiazepines, but more likely to report taking antipsychotics than Caucasians. CONCLUSIONS: The present findings reinforce previous reports regarding the chronicity and severity of bipolar disorder among African-Americans. They also support previous studies that found high rates of attempted suicide among African-Americans with bipolar disorder. These findings provide further impetus for specific community and mental health services delivery efforts to reduce barriers to early accurate diagnosis and to appropriate ambulatory treatment for bipolar disorder.     

Symptom heterogeneity in comorbid alcohol disorder

The heterogeneity of signs and symptoms of alcohol disorder was examined in a community sample of 1,955 persons with either alcohol disorder alone or alcohol disorder plus one of four categories of major mental disorder (antisocial personality disorder, schizophrenia, affective disorder, anxiety disorder). When all diagnostic categories were combined, persons with comorbid mental and alcohol disorders showed evidence of more severe alcohol-related symptoms than did persons with alcohol disorder alone. Distinct symptom patterns distinguished the four diagnostic groups, reflecting heterogeneity in the manifestation of comorbid alcohol disorder. Most notably, comorbid antisocial personality disorder and schizophrenia were associated with higher levels of alcohol consumption and more severe social consequences of alcohol use. These findings substantiate the need for development of specialized dual diagnosis programs and suggest that additional specialization may be required to address diagnostic group differences in the characteristics of comorbid alcohol disorder.     

Which temperamental characteristics are associated with substance use in subjects with psychotic and mood disorders?

The aim of this study was to assess the associations between substance use disorders and temperamental characteristics in subjects with non-affective psychotic disorders or mood disorders. Consecutively hospitalized patients were interviewed with a structured diagnostic interview to define DSM-IV diagnoses, including those of substance use. Temperamental characteristics were measured using the Sensation-Seeking Scale (SSS), the Barratt Impulsivity Scale (BIS) and the Physical Anhedonia Scale. Inpatients (n=103) with non-affective psychotic disorders (n=45) or mood disorders (n=58) were included. Among these patients, 25.2% presented with a lifetime (LT) history of alcohol abuse/dependence and 23.3% presented with a LT history of cannabis abuse/dependence. A LT history of alcohol misuse was independently associated with higher scores at the 'experience seeking' and 'disinhibition' subscales of the SSS. A LT history of cannabis misuse was independently associated with higher scores on the 'disinhibition' subscale of the SSS and on the 'non-planning activity' subscale of the BIS. These results suggest that sensation-seeking and impulsivity are temperamental characteristics that may favor substance use in patients with psychotic or mood disorders, independently from categorical diagnoses.

Personality disorders, history of trauma, and posttraumatic stress disorder in subjects with anxiety disorders

The purpose of the study was to examine the association of personality disorders, history of trauma, and posttraumatic stress disorder (PTSD) in a large sample of subjects with anxiety disorders. Categorical and continuous indices of personality disorders were compared in three groups from the Harvard/Brown Anxiety Disorders Research Project (HARP): subjects with no history of trauma (n = 403), subjects with a history of trauma but no history of PTSD (n = 151), and subjects with a current or past diagnosis of PTSD (n = 68). Subjects with PTSD were more likely to meet criteria for borderline or self-defeating personality disorder than subjects in the other two groups. PTSD subjects also had higher scores on the continuous measures (total number of criteria met) for borderline and self-defeating personality disorder than the other two groups. The findings suggest that a diagnosis of PTSD rather than a history of trauma is associated with borderline and self-defeating personality disorder features. Alternative conceptualizations of axis II features in individuals with PTSD are discussed.     

Gender differences in firesetting: results from the national epidemiologic survey on alcohol and related conditions (NESARC)

This study presents gender differences in sociodemographics and in psychiatric correlates of firesetting in the United States. Data were derived from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a representative sample of U.S. adults. Face-to-face interviews of more than 43,000 adults were conducted in the 2001-2002 period. This study focused on the 407 subjects with a lifetime history of firesetting. The prevalence of lifetime firesetting in the U.S. was 1.7% in men and 0.4% in women. Firesetting was significantly associated with a wide range of antisocial behaviors that differed by gender. Multivariate logistic regression analyses indicated associations in both genders with psychiatric and addictive disorders. Men with a lifetime history of firesetting were significantly more likely than men without such history to have lifetime generalized anxiety disorder as well as a diagnosis of conduct disorder, antisocial personality disorder, alcohol or cannabis use disorder, and obsessive-compulsive personality disorder. Women with a lifetime history of firesetting were significantly more likely than women without such history to have lifetime alcohol or cannabis use disorder, conduct disorder, and antisocial or obsessive compulsive personality disorder, as well as psychotic disorder, bipolar disorder or schizoid personality disorder. Women with a lifetime history of firesetting were significantly more likely than men with such history to have a lifetime diagnosis of alcohol abuse and antisocial personality disorder as well as a diagnosis of schizoid personality disorder. Our findings indicate that firesetting in women could represent a behavioral manifestation of a broader spectrum than firesetting in men.     

Clinical features, psychiatric comorbidity, and health-related quality of life in persons reporting compulsive computer use behavior

BACKGROUND: We sought to examine the demographic and clinical features and psychiatric comorbidity in persons reporting compulsive computer use. METHOD: Sixteen men and 5 women were recruited by advertisement and word-of-mouth. All reported excessive computer use that interfered with social or occupational functioning or caused personal distress. The subjects completed structured and semistructured assessments, including a computer version of the Diagnostic Interview Schedule (DIS), the Minnesota Impulsive Disorders Interview, the Personality Diagnostic Questionnaire-Revised (PDQ-R), and a brief version of the Medical Outcome Study Short Form-36 (SF-36). RESULTS: The typical subject was a 32-year-old single white man with a mean yearly income of $27,000; problem computer use began at age 29 and consumed 27 hours each week. Eleven subjects (52%) reported school or academic problems resulting from their computer use, and 12 (57%) reported that family members had confronted them about it. Thirteen subjects (62%) had tried to cut back on their computer usage. Nine subjects (43%) reported missing work or school owing to their computer use. According to DIS results, 7 subjects (33%) had a lifetime mood disorder, 8 subjects (38%) had a substance use disorder, and 4 subjects (19%) had a lifetime anxiety disorder. According to the PDQ-R results, 11 subjects (52%) met criteria for at least one personality disorder, the most frequent being the borderline, antisocial, and narcissistic types. Impulse-control disorders were also common, particularly compulsive buying. On the SF-36, subjects showed impaired mental health functioning compared with a normative sample. CONCLUSION: The results show that persons reporting compulsive computer use suffer substantial psychiatric comorbidity and show evidence of emotional distress. While the disorder appears to be increasing in prevalence, more work is needed to determine its relationship with other disorders and to determine its risk factors, family history, psychosocial complications, and natural history.     

Family history of psychiatric illness as a risk factor for schizoaffective disorder: a Danish register-based cohort study

BACKGROUND: Schizoaffective disorder may be related to both schizophrenia and bipolar disorders, but no population-based studies, to our knowledge, have investigated this association in families. OBJECTIVES: To determine whether a psychiatric history of schizoaffective disorder, bipolar disorder, or schizophrenia among parents and siblings is a risk factor for developing a schizoaffective disorder, and whether a specific pattern of family history of psychiatric illness exists in persons with schizoaffective disorder compared with persons with bipolar disorder or schizophrenia. DESIGN: Register-based cohort study. SETTING: Denmark. COHORT: The 2.4 million persons born in Denmark after 1952. MAIN OUTCOME MEASURES: Relative risks of the 3 illnesses estimated by Poisson regression. RESULTS: In total, 1925 persons had a schizoaffective disorder, 3721 had a bipolar disorder, and 12 501 had schizophrenia. The relative risk of schizoaffective disorder was 2.76 (95% confidence interval, 2.49-3.06) if a first-degree relative had a history of mental illness compared with a person with no first-degree relatives with such a history. There was an additional risk (95% confidence interval) of 2.57 (2.11-3.13), 3.23 (2.63-3.95), or 1.92 (1.43-2.57) if the first-degree relative had schizophrenia, bipolar disorder, or schizoaffective disorder, respectively, compared with other psychiatric admissions. When bipolar disorder was the outcome, bipolar disorder in first-degree relatives was by far the significantly strongest risk factor. When schizophrenia was the outcome, the significantly strongest risk factor was schizophrenia among first-degree relatives. CONCLUSION: Schizoaffective disorder is not simply a subgroup of either bipolar disorder or schizophrenia but may be genetically linked to both, with schizoaffective disorder being a subtype of each or a genetic intermediate form.     

Physicians' diagnoses of psychiatric disorders for people with chronic fatigue syndrome

OBJECTIVE: To examine rates of psychiatric diagnoses given by patients' primary or regular physicians to persons with chronic fatigue syndrome (CFS), persons with psychiatrically explained fatigue, and a control group. Physicians' psychiatric diagnosis and participants' self-reported psychiatric diagnoses were compared to lifetime psychiatric diagnoses as measured by a structured psychiatric interview. METHOD: Participants were recruited as part of a community-based epidemiology study of chronic fatigue syndrome. Medical records of 23 persons with chronic fatigue syndrome, 25 persons with psychiatrically explained chronic fatigue, and 19 persons without chronic fatigue (controls) were examined to determine whether their physician had given a diagnosis of mood, anxiety, somatoform, or psychotic disorder. Lifetime psychiatric status was measured using the Structured Clinical Interview for the DSM-IV (SCID). Participants' self reports of specific psychiatric disorders were assessed as part of a detailed medical questionnaire. RESULTS: Physicians' diagnosis of a psychiatric illness when at least one psychiatric disorder was present ranged from 40 percent in the psychiatrically explained group, 50 percent in the control group, and 64.3 percent in the CFS group. Participants in the psychiatrically explained group were more accurate than physicians in reporting the presence of a psychiatric disorder, and in accurately reporting the presence of a mood or anxiety disorder. CONCLUSIONS: The present investigation found underrecognition of psychiatric illness by physicians, with relatively little misdiagnosis of psychiatric illness. Physicians had particular difficulty assessing psychiatric disorder in those patients whose chronic fatigue was fully explained by a psychiatric disorder. Results emphasized the importance of using participant self report as a screening for psychiatric disorder.
