Abstract
OBJECTIVE Tens of millions of individuals with mental health problems interact with the U.S. criminal legal system (including 911, police, jail detention and sentences, courts, and probation and parole) each year. The authors sought to identify recommended mental health practices for criminal legal system-involved individuals and report the percentages of U.S. counties and of the U.S. population living in counties in which each recommended practice is present. METHODS Recommended practices for criminal legal-involved individuals with mental health problems were identified from meta-analyses, reviews, and best practice recommendations. Up to four respondents per county (i.e., jail, probation, community mental health, and community substance use treatment administrators) from 950 counties were asked whether each recommended practice was present for criminal legal-involved individuals. Weighted percentages of U.S. counties using recommended practices and of the U.S. population living in counties with each recommended practice are reported. RESULTS Fifty-nine recommended practices, including general mental health approaches (e.g., permanent supportive housing, Medicaid continuity) and diagnosis-specific mental health treatments (including medications and psychotherapies), were identified. Weighted data from respondents (N=791 from 519 counties) indicated that each recommended practice was present for criminal legal-involved individuals in only 21.9%-43.0% of U.S. counties. CONCLUSIONS These results inform implementation efforts by indicating the presence of recommended care practices for criminal legal-involved individuals with mental health problems in counties nationwide. Because supportive housing, access to Medicaid reactivation in jails, and psychosocial interventions for physical pain have low presence but high importance for recovery, implementation efforts might first target these approaches.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024; 123:104283. [PMID: 38109837 DOI: 10.1016/j.drugpo.2023.104283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 11/18/2023] [Accepted: 11/29/2023] [Indexed: 12/20/2023]
Abstract
BACKGROUND Little is known about global practices regarding the provision of reimbursement for the participation of people who are incarcerated in research. To determine current practices related to the reimbursement of incarcerated populations for research, we aimed to describe international variations in practice across countries and carceral environments to help inform the development of more consistent and equitable practices. METHODS We conducted a scoping review by searching PubMed, Cochrane library, Medline, and Embase, and conducted a grey literature search for English- and French-language articles published until September 30, 2022. All studies evaluating any carceral-based research were included if recruitment of incarcerated participants occurred inside any non-juvenile carceral setting; we excluded studies if recruitment occurred exclusively following release. Where studies failed to indicate the presence or absence of reimbursement, we assumed none was provided. RESULTS A total of 4,328 unique articles were identified, 2,765 were eligible for full text review, and 426 were included. Of these, 295 (69%) did not offer reimbursement to incarcerated individuals. A minority (n = 13; 4%) included reasons explaining the absence of reimbursement, primarily government-level policies (n = 7). Among the 131 (31%) studies that provided reimbursement, the most common form was monetary compensation (n = 122; 93%); five studies (4%) offered possible reduced sentencing. Reimbursement ranged between $3-610 USD in total and 14 studies (11%) explained the reason behind the reimbursements, primarily researchers' discretion (n = 9). CONCLUSIONS The majority of research conducted to date in carceral settings globally has not reimbursed incarcerated participants. Increased transparency regarding reimbursement (or lack thereof) is needed as part of all carceral research and advocacy efforts are required to change policies prohibiting reimbursement of incarcerated individuals. Future work is needed to co-create international standards for the equitable reimbursement of incarcerated populations in research, incorporating the voices of people with lived and living experience of incarceration.

Abstract
PURPOSE High rates of psychiatric disorders in correctional facilities have fueled widespread concern about the "criminalization of mental illness." While the link between incarceration, substance abuse, and antisocial-personality disorder is well established, the relationship between non-substance-related psychiatric disorders and incarceration has not been thoroughly investigated. This study examines the association of mental illness, excluding substance use disorders, with risk for incarceration in US adults. METHODS Nationally representative data from the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III) were used to compare the proportions of respondents with lifetime incarceration among those with no lifetime history of DSM-5 disorders, or with lifetime history of mental illness, substance use disorders, dual diagnosis, and antisocial personality/conduct disorder. Logistic regression analysis was used to examine the independent association of incarceration with mental illness alone, both in comparison to and net of associations with sociodemographic and behavioral characteristics. RESULTS Among adults with mental illness alone, 6.7% reported past incarceration, compared to 4.8% with no history of DSM-5 disorders, and 20-40% in other DSM-5 diagnostic groups. Sociodemographic and behavioral risk factors were more strongly associated with incarceration (c-statistics = 0.74 and 0.77, respectively), than mental illness (c-statistic = 0.56). Schizophrenia or other psychoses and borderline personality disorder were independently associated with incarceration, but with effect sizes no greater than eight other sociodemographic or behavioral risk factors. CONCLUSION A weak association of mental illness alone with incarceration was found, despite high level of public attention to "criminalization of mental illness."

Clinical Impact of Psychopathy on Bipolar Disorder. Medicina (B Aires) 2021; 57:medicina57020165.

Abstract
Background and Objectives. Bipolar disorder (BD) is associated with a significant burden due to affective symptoms and behavioral manifestations, but also cognitive and functional impairment. Comorbidity with other psychiatric conditions, including personality disorders, is frequent. The comorbidity with psychopathy deserves special consideration given that both disorders share some clinical characteristics, such as grandiosity, risky behavior or poor insight, among others, that can worsen the outcome of BD. Therefore, this study aimed to evaluate the prevalence of psychopathy in a sample of clinically stabilized patients with BD and its impact on the severity of BD. Materials and Methods. A sample of 111 patients with BD (38 type I and 73 type II) was studied. The Hamilton Depression Rating Scale (HAM-D) and the Young Mania Rating Scale (YMRS) served to assess the severity of BD. Psychopathy was measured by means of the Psychopathic Personality Inventory-Revised (PPI-R). Patients were divided into three groups according to the severity of psychopathy (Group 1: no psychopathy; Group 2: “psychopathic” trait; Group 3: clinical psychopathy). Other measures regarded impulsiveness (Barratt Impulsiveness Scale-11, BIS-11) and empathy (Empathy Quotient, EQ). Comparisons of mania, depression, impulsivity and empathy scores were run with MANOVA considering psychopathy and diagnosis as independent variables. Results. The prevalence of psychopathy was 5.4%. A significant association between the level of psychopathy and YMRS, attentional/cognitive impulsivity and motor impulsivity scores emerged. No interaction between psychopathy and BD diagnosis was found. Post hoc analysis demonstrated significantly higher YMRS scores in Group 3 than in Group 1; that is, patients with psychopathy have more manic symptoms. Conclusion. Psychopathy seems quite frequent among patients with BD. The association of psychopathy with BD results in higher impulsivity and manic symptoms. In light of this, psychopathy should be investigated when assessing patients with BD, regardless of the comorbidity of BD with other personality disorders.

Abstract
Background: The Mood Disorder Questionnaire (MDQ) is a frequently used screening tool for the early detection of Bipolar Disorder (BD), which is often unrecognized or misdiagnosed at its onset. In this study, data from Tunisia has been used to evaluate the psychometric properties of the Arabic MDQ. Methods: The sample included 151 patients with a current major depressive episode. The Arabic adapted version of the Structured Clinical Interview for DSM-IV-TR was used to formulate a diagnosis, yielding 62 patients with BD and 89 with unipolar Major Depressive Disorder (MDD). Principal component analysis with parallel analysis was used to establish the spontaneous distribution of the 13 core items of the MDQ. Confirmatory Factor Analysis (CFA) was used to check the available factor models. Receiver Operating Characteristic (ROC) analysis was used to assess the capacity of the MDQ to distinguish patients with BD from those with MDD. Results: Cronbach’s α in the sample was 0.80 (95%CI: 0.75 to 0.85). Ordinal α was 0.88. Parallel analysis suggested two main components, which explained 59% of variance in the data. CFA found a good fit for the existing unidimensional, the two-factor, and the three-factor models. ROC analysis showed that at a threshold of 7, the MDQ was able to distinguish patients with BD from those with MDD with extraordinary negative predictive value (0.92) and a positive diagnostic likelihood ratio of 3.8. Conclusion: The Arabic version of the MDQ showed good measurement properties in terms of reliability, factorial validity and discriminative properties.

Abstract
AbstractObjectiveTo evaluate the performance of the French version of the Mood Disorder Questionnaire (MDQ) in patients attending a general psychiatric outpatient service as well as whether MDQ scores are independent of patient mood state at time of completion.Method183 patients completed the MDQ and were assessed with the MADRS and YMRS scales, before being interviewed with the SCID (time 1). MDQ, MADRS and YMRS assessment was repeated four to six weeks later (time 2).ResultsAccording to the SCID, 44 patients were suffering from bipolar spectrum disorder and 102 from unipolar disorder (37 patients dropped out). The MDQ provided high specificity (83.3%). Sensitivity was 63.6%, with better identification of bipolar I (85.0%) than bipolar II patients (45.8%). In the whole sample, test-retest reliability was satisfactory (kappa = 0.64). Modest correlations were observed between the number of endorsed MDQ items and YMRS scores at time 1 (Spearman r = 0.19; p = 0.021) and time 2 (r = 0.26; p = 0.002).ConclusionsDespite some fluctuations over time and a discrete influence of symptom severity, the screening algorithm can be used reliably, whether in the acute or remission phase of a depressive episode.

Abstract
Given the time demands of clinical practice it is not surprising that diagnoses are sometimes missed. To improve diagnostic recognition, self-administered screening scales have been recommended. A problem with much of the research effort on screening scales is the confusion between diagnostic testing and screening. It is important for a screening test to have high sensitivity because the more time intensive/expensive follow-up diagnostic inquiry will presumably only occur in patients who are positive on the initial screen. Investigators vary in how they analyze their data in determining the recommended cutoff score on a self-administered screening questionnaire. To illustrate this, in the present report we examined how often each of the different approaches towards determining a cutoff score on bipolar disorder screening scales were used. We reviewed 68 reports of the performance of the 3 most commonly researched bipolar disorder screening scales to determine how the recommended cutoff on the scale was derived. Most studies recommended a cutoff point on the screening scale that optimized the level of agreement with the diagnostic gold standard. Only 11 (16.2%) studies recommended a cutoff that prioritized the scale's sensitivity. It is important for clinicians to understand the difference between screening and diagnostic tests. The results of the present study indicate that most studies of the performance of the 3 most commonly studied bipolar disorder screening measures have taken the wrong approach in deriving the cutoff score on the scale for the purpose of screening.

Abstract
Although personality disorders (PDs) are highly comorbid with bipolar spectrum disorders (BSDs), little longitudinal research has been conducted to examine the prospective impact of PD symptoms on the course of BSDs. The aim of this study is to examine whether PD symptom severity predicts shorter time to onset of bipolar mood episodes and conversion to bipolar I disorder over time among individuals with less severe BSDs. Participants (n = 166) with bipolar II disorder, cyclothymia, or bipolar disorder not otherwise specified completed diagnostic interview assessments of PD symptoms and self-report measures of mood symptoms at baseline. They were followed prospectively with diagnostic interviews every 4 months for an average of 3.02 years. Cox proportional hazard regression analyses indicated that overall PD symptom severity significantly predicted shorter time to onset of hypomanic (hazard ratio [HR] = 1.42; p < .001) and major depressive episodes (HR = 1.51; p < .001) and conversion to bipolar I disorder (HR = 2.51; p < .001), after controlling for mood symptoms. Results also suggested that cluster B severity predicted shorter time to onset of hypomanic episodes (HR = 1.38; p = .002) and major depressive episodes (HR = 1.35; p = .01) and conversion to bipolar I disorder (HR = 2.77; p < .001), whereas cluster C severity (HR = 1.56; p < .001) predicted shorter time to onset of major depressive episodes. These results support predisposition models in suggesting that PD symptoms may act as a risk factor for a more severe course of BSDs. (PsycINFO Database Record

Abstract
BACKGROUND Bipolar disorder (BD) is difficult to diagnose in the early stages of the illness, with the most frequent misdiagnosis being major depressive disorder (MDD). We aimed to use a regional homogeneity (ReHo) approach with resting-state functional magnetic resonance imaging (rs-fMRI) to investigate the features of spontaneous brain activity in MDD patients screening positive on the 32-item Hypomania Checklist (HCL-32). METHODS Nineteen MDD patients screening positive (HCL-32(+); 9 males; 24.9±5.7 years) and 18 patients screening negative (HCL-32(-); 9 males; 27.1±6.7 years), together with 24 healthy controls (HC; 11 males; 26.4±3.9 years) were studied. ReHo maps were compared and an receiver operating characteristic (ROC) analysis was conducted to confirm the utility of the identified ReHo differences in classifying the patients. RESULTS The MDD versus HC showed different ReHo in many brain areas, especially in the frontal and parietal cortex. The HCL-32(+) versus HCL-32(-) showed significant increase of ReHo in the right medial superior frontal cortex, left inferior parietal cortex and middle/inferior temporal cortex, and decrease of ReHo in the left postcentral cortex and cerebellum. ROC analysis showed good sensitivity and specificity for distinguishing these two subgroups of MDD. LIMITATIONS Recruited patients were all on antidepressants and standard mania rating scales were not performed to assess their hypomanic symptoms. CONCLUSIONS The rs-fMRI measurement of ReHo in distributed brain regions may be putative biomarkers which could differentiate subthreshold BD from MDD.

Abstract
Mental health problems are disproportionately represented in the community corrections system with limited information on the epidemiology of mental health and correlated factors such as suicide among probationers. This study recruited 2,077 probationers who completed screeners for mental health and substance disorders and suicide risk. Results found 13% of probationers were at high risk of suicide. Those who screened positive for a mental health condition were between 2 and 8 times more likely to screen positive for suicide risk. Allocation of additional resources to mental health in the criminal justice system and to effectively coordinate existing mental health services is needed.

Abstract
Background The aim of this study was to test the ability of the Chinese version of the Mood Disorder Questionnaire (MDQ) to identify Bipolar Disorders (BD) in patients diagnosed with Major Depressive Disorder (MDD) or Unipolar Disorder (UD) in the clinical setting. Methods 1,487 being treated for MDD or UD at 12 mental health centers across China, completed the MDQ and subsequently examined by the Mini International Neuropsychiatric Interview (MINI). Receiver Operating Characteristic(ROC) curves were used to determine the ability of the MDQ to differentiate between BD (BD, BD-I and BD-II) and MDD or UD and patients with BD-I from patients with BD-II. Results Of the 1,487 patients, 309 (20.8%) satisfied the DSM-IV criteria for BD: 118 (7.9%) for BD-I and 191 (12.8%) for BD-II. When only part one of the MDQ was used, the best cutoff was 7 between BD and UD (sensitivity 0.66, specificity 0.88, positive predictive value 0.59, negative predictive value 0.91), 6 between BD-II and UD, and 10 between BD-I and BD-II. If all three parts of the MDQ were used, the MDQ could not distinguish between BD and UD at a cutoff of 7 (or 6), and the sensitivity was only 0.22 (or 0.24). Conclusion The Chinese version of the MDQ had good psychometric features in screening bipolar disorders from depressive patients with mood disorders when part two and part three of the MDQ were ignored.

[PMID: 24485982 DOI: 10.1016/j.comppsych.2013.11.022] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2013] [Revised: 11/25/2013] [Accepted: 11/27/2013] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND It is well known that patients with bipolar disorder are more prone to violence and have more criminal behaviors than general population. A strong relationship between criminal behavior and inability to empathize and imperceptions to other person's feelings and facial expressions increases the risk of delinquent behaviors. In this study, we aimed to investigate the deficits of facial emotion recognition ability in euthymic bipolar patients who committed an offense and compare with non-delinquent euthymic patients with bipolar disorder. METHOD Fifty-five euthymic patients with delinquent behaviors and 54 non-delinquent euthymic bipolar patients as a control group were included in the study. Ekman's Facial Emotion Recognition Test, sociodemographic data, Hare Psychopathy Checklist, Hamilton Depression Rating Scale and Young Mania Rating Scale were applied to both groups. RESULTS There were no significant differences between case and control groups in the meaning of average age, gender, level of education, mean age onset of disease and suicide attempt (p>0.05). The three types of most committed delinquent behaviors in patients with euthymic bipolar disorder were as follows: injury (30.8%), threat or insult (20%) and homicide (12.7%). The best accurate percentage of identified facial emotion was "happy" (>99%, for both) while the worst misidentified facial emotion was "fear" in both groups (<50%, for both). The total accuracy rate of recognition toward facial emotions was significantly impaired in patients with delinquent behaviors than non-delinquent ones (p<0.05). The accuracy rate of recognizing the fear expressions was significantly worse in the case group than in the control group (p<0.05). In addition, it tended to be worse toward angry facial expressions in criminal euthymic bipolar patients. The response times toward happy, fear, disgusted and angry expressions had been significantly longer in the case group than in the control group (p<0.05). CONCLUSION This study is the first, searching the ability of facial emotion recognition in euthymic patients with bipolar disorder who had delinquent behaviors. We have shown that patients with bipolar disorder who had delinquent behaviors may have some social interaction problems i.e., misrecognizing fearful and modestly anger facial emotions and need some more time to response facial emotions even in remission.

Abstract
The criminal justice system is the primary service delivery system for many adults with drug and alcohol dependence, mental health, and other health service needs. The purpose of this study was to examine the relationship between risk of future offense, mental health status and co-occurring disorders in a large substance abuse diversion probationer population. A purposive sample of 2,077 probationers completed an assessment to screen for mental health disorders, substance use disorders, risk of future crime and violence, and several demographic characteristics. Probationers who screened positive for co-occurring substance use and mental health disorders were significantly more likely to be at higher risk of future crime and violence compared to probationers who screened positive for only substance use, only a mental health disorder, or no substance use or mental health disorder. Implications for substance use and mental health service delivery are discussed, and recommendations are made for further research.

Abstract
BACKGROUND The introduction of screening questionnaires, such as the Mood Disorder Questionnaire (MDQ), has stimulated clinical and epidemiological studies on bipolar disorders. In this work, we studied the item response pattern of the MDQ in the Italian population and compared the results with those of the validation of the MDQ in Asian studies (Chinese and Korean), analyzing similarities and differences among the populations studied. METHODS The sample was made up of 2278 participants, distributed as follows: 56.6% females, 50.8% living in the north-central Italy, and 33.7% living in rural areas. The factor analysis was run on the matrix of tetrachoric correlations. The psychometric properties of the MDQ were also studied using the Rasch logistic model. RESULTS The parallel analysis found two significant components. The first includes symptoms referring to acceleration, danger and irritability as risky behaviors, social interaction problems and mental flow. The second includes symptoms referring to self-confidence and energy. With respect to the Korean/Chinese results, the Italian sample, item 11 ("much more sex"), appears related to self-confidence and energy, while in Asia it is connected with items expressing risky behaviors and irritability. LIMITATIONS Differences in the frequency of comorbid disorders in Asian and Italian populations should be considered. The results should be confirmed and compared with those of other populations. CONCLUSIONS Cultural differences appear to be associated with a different symptomatic expression of bipolar spectrum disorders. Future research will investigate the role of gene-environment interaction in the genesis of these differences.

Abstract
INTRODUCTION The objective was to estimate the rate of subjects who tested positive at a screening for bipolar disorders among the people insured by a French Health Company, and subsequently to measure treatment patterns. METHODS Cross-sectional postal survey on the "Mutuelle Générale de l'Education Nationale" (MGEN) policyholders. A self-rated questionnaire was sent by mail to 20,099 individuals randomly selected among MGEN policyholders. Tools: questionnaire on socio-demographic variables and health-care use; Mood Disorder Questionnaire (MDQ); Composite International Diagnostic Interview Short Form Self-Administered (CIDI-SA). RESULTS Responders were 10,288 (53%). The prevalence of MDQ positivity (MDQ(+)) was 3.6%. The respondents older than 65 showed the lowest frequencies. High frequencies were recorded by the people who had left work because of long term sickness and by people with invalidity. Subjects having a diagnosis of ICD-10 major depression were found to be at risk. Positive subjects had no more contacts with general practitioners than negative subjects; on the contrary they had more contacts with psychiatrists, alternative medicine professionals, psychologists, psychoanalysts, spiritual guides or welfare workers. MDQ+ subjects had a higher risk to use all kinds of psychodrugs, including antidepressants (27.7%, OR=2.7, CI95% 1.9-3.9). DISCUSSION The prevalence of MDQ(+) was similar to the surveys in the USA and Italy. The use of ADs in people with MDQ(+) and MDD diagnosis needs to be taken into account when managing the public health-care system. A large rate of positive subjects reported to have used ineffective treatments for bipolar disorders. LIMITS Relative low response rate and observational design.

Abstract
BACKGROUND Interactions between characteristics of bipolar and Axis II cluster B disorders are clinically and diagnostically challenging. Characteristics associated with personality disorders may be dimensional aspects of bipolar disorder. We investigated relationships among antisocial personality disorder (ASPD) or borderline personality disorder symptoms, impulsivity, and course of illness in bipolar disorder. METHODS Subjects with bipolar disorder were recruited from the community. Diagnosis was by structured clinical interview for DSM-IV (SCID-I and -II), psychiatric symptom assessment by the change version of the schedule for affective disorders and schizophrenia (SADS-C), severity of Axis II symptoms by ASPD and borderline personality disorder SCID-II symptoms, and impulsivity by the Barratt impulsiveness scale (BIS-11). RESULTS ASPD and borderline symptoms were not related to clinical state or affective symptoms. Borderline symptoms correlated with BIS-11 impulsivity scores, and predicted history of suicide attempts independently of the relationship to impulsivity. ASPD symptoms were more strongly related to course of illness, including early onset, frequent episodes, and substance-related disorders. These effects persisted after allowance for gender and substance-use disorder history. CONCLUSIONS Personality disorder symptoms appear to be dimensional, trait-like characteristics of bipolar disorder. ASPD and Borderline symptoms are differentially related to impulsivity and course of illness.

Abstract
OBJECTIVES Bipolar disorder (BD) is frequently misdiagnosed as major depressive disorder (MDD), which may lead to inappropriate treatment and poor outcomes. This study aimed to compare demographic and clinical features between patients with MDD and those with BD, but being misdiagnosed as MDD, in China. METHODS A total of 1487 patients diagnosed with MDD were consecutively evaluated in 13 psychiatric hospitals or psychiatric units of general hospitals nationwide in China. The patients' sociodemographic and clinical characteristics were recorded using a standardized protocol and data collection procedure. The Mini-International Neuropsychiatric Interview (MINI) was used to establish DSM-IV diagnoses, and identify patients with MDD and those with BD, but being misdiagnosed with MDD. RESULTS The proportions of BD (all types), bipolar I disorder (BD-I), and bipolar II disorder (BD-II) misdiagnosed as MDD in clinical practice were 20.8%, 7.9%, and 12.8%, respectively. Multiple logistic regression analyses revealed that compared to MDD patients, BD-I was characterized by more atypical depressive features (increased appetite, increased sleep, and weight gain) [odds ratio (OR) = 2.0, 95% confidence interval (CI): 1.2-3.2], more psychotic symptoms (OR = 2.1, 95% CI: 1.3-3.5), more lifetime depressive episodes (OR = 1.1, 95% CI: 1.1-1.2), and earlier age of onset (OR = 0.97, 95% CI: 0.9-0.99); BD-II was characterized by more psychotic symptoms (OR = 2.1, 95% CI: 1.4-3.1) and earlier age of onset (OR = 0.96, 95% CI: 0.9-0.97). In addition, compared to BD-II patients, BD-I patients were characterized by more frequent depressive episodes per year (OR = 3.1, 95% CI: 1.5-6.6). CONCLUSIONS Depressive episodes in the context of BD-I and BD-II, among those who were misclassified as MDD, present some different clinical features compared to MDD. This finding should be taken into account in guiding diagnostic practices in China.

Abstract
BACKGROUND Bipolar disorder (BD) is often misdiagnosed as a major depressive disorder (MDD). This study aimed to test the usefulness of the screening tool, the Mood Disorders Questionnaire (MDQ), to identify BD patients misdiagnosed as MDD in Chinese clinical settings. METHODS A total of 1487 patients treated for MDD were consecutively examined in 13 mental health centers in China. The patients' socio-demographic and clinical characteristics were recorded using a standardized protocol and data collection procedure. The MDQ was completed by patients to identify symptoms characteristic of BD. DSM-IV diagnoses were established using the Mini International Neuropsychiatric Interview (MINI). RESULTS Three hundred-nine of the 1487 patients (20.8%) satisfied DSM-IV criteria for BD; 118 (7.9%) for BD-I and 191 (12.8%) for BD-II on the MINI. The optimal cut-off point on the MDQ to differentiate BD from MDD was 3, while cut-off points of 5 and 3 differentiated BD-I and BD-II from MDD, respectively. The maximum sensitivity was 0.31, 0.45 and 0.22 for differentiating BD, BD-I and BD-II from MDD, respectively. CONCLUSIONS The optimal cutoff points of the MDQ for screening BD in Chinese patients originally diagnosed as MDD were considerably lower than those in earlier studies. The routine clinical use of the MDQ as a screening scale for BD in Chinese patients treated for MDD does not seem to be justified.

Abstract
OBJECTIVE Bipolar disorder (BD) is frequently misdiagnosed as major depressive disorder (MDD), which may lead to inappropriate treatment and poor outcomes. This study aimed to examine prescribing patterns of antidepressants, antipsychotics and mood stabilizers in BD patients misdiagnosed with MDD in China. METHODS A total of 1487 patients originally diagnosed with MDD were consecutively screened for diagnostic revision in 13 psychiatric hospitals or psychiatric units of general hospitals in China nationwide. The patients' sociodemographic and clinical characteristics were recorded using a standardized protocol and data collection procedure. The Mini International Neuropsychiatric Interview (MINI) was used to establish DSM-IV diagnoses. Data on psychotropic prescriptions were collected by a review of medical records. RESULTS Three hundred and nine of the 1487 patients (20.8%) fulfilled DSM-IV criteria for BD; 118 (7.9%) for BD-I and 191 (12.8%) for BD-II on the MINI. Of the BD patients (n = 309), 227 (73.5%) received any use of antidepressants, 73 (23.6%) antipsychotics and 33 (10.7%) mood stabilizers. In multiple logistic regression analyses, compared with those with MDD, patients with BD-I were more likely to receive antidepressants (OR 1.7, 95% CI 1.1-2.8, p = 0.02), antipsychotics (OR 1.6, 95% CI 1.04-2.5, p = 0.04) and mood stabilizers (OR 3.9, 95% CI 2.1-7.2, p < 0.001), whereas patients with BD-II were more likely to receive mood stabilizers (OR 2.4, 95% CI 1.3-4.4, p = 0.003). There was no difference in the use of antidepressants (OR 1.1, 95% CI 0.8-1.5, p = 0.7) and antipsychotics (OR 1.3, 95% CI 0.9-1.9, p = 0.2) between BD-II and MDD. In addition, there was no difference between BD-I and BD-II in any use of antidepressants, antipsychotics and mood stabilizers. CONCLUSIONS The prescription of antidepressants for BD patients misdiagnosed with MDD is very common, and only a very small proportion of patients received guideline-concordant treatment. Considering the potentially hazardous effects of inappropriate pharmacotherapy in this population, continuing education and training addressing the correct diagnosis of BD and rational use of psychotropic medications are needed in China.

Abstract
BACKGROUND Bipolar disorder (BD) is a recurrent, complex illness and often misdiagnosed and treated as a major depressive disorder (MDD). This study set out (1) to investigate the proportion of BD in patients treated for MDD using DSM-IV diagnostic criteria; (2) to test the usefulness of the screening tool - the 32-item Hypomania Checklist (HCL-32) in Chinese patients; and (3) to assess whether MDD patients with subthreshold manic features (patients who screened positive for BD on the HCL-32, but did not meet the diagnostic criteria for DSM-IV BD as measured by Mini International Neuropsychiatric Interview (MINI)) differ from those with BD, and from those suffering from MDD without manic features in terms of basic demographic and clinical variables. METHODS A total of 1487 patients treated for MDD were consecutively examined in 13 mental health centers in China. The patients' socio-demographic and clinical characteristics were recorded using a standardized protocol and data collection procedure. The HCL-32 was self-completed by patients to identify hypomanic symptoms, and the MINI was used by clinicians to establish DSM-IV diagnoses. RESULTS The proportions of undiagnosed BD (all types), BD-I and BD-II were 20.8%, 7.9% and 12.8%, respectively. The HCL-32 had low positive predictive value (0.43). Compared to MDD patients without subthreshold manic features, MDD patients with subthreshold manic features were younger at onset, less likely to be married and had more depressive episodes on a seasonal basis, and more frequent depressive episodes overall. Compared to BD patients, MDD patients with subthreshold manic features had an older age at onset and less frequent depressive episodes and less family history of psychiatric disorders, appetite, weight gain and time spent sleeping, suicide ideation and attempts and psychotic symptoms. CONCLUSIONS At least one fifth of Chinese patients treated for MDD may have an undiagnosed BD. The HCL-32 is useful to identify broader subthreshold bipolar features. The findings need to be confirmed by longitudinal studies using more comprehensive, standardized instruments.

Abstract
BACKGROUND Screening properties of the mood disorder questionnaire (MDQ) to detect bipolar disorder (BD) in patients with substance use disorders are unknown. METHODS 403 treatment seeking patients with a substance use disorder completed the MDQ and subsequently 111 MDQ positives and 59 MDQ negatives were assessed with the Structured Clinical Interview for DSM-IV to diagnose BD. In addition, given the overlap with BD symptoms, the presence of borderline personality disorder (BPD), antisocial personality disorder (APD) and attention deficit/hyperactivity disorder (ADHD), were assessed using the Diagnostic Interview Schedule and the Structured Interview for DSM-IV Personality. RESULTS Of the 170 patients with a SCID interview, 35 patients (20.6%) met criteria for a lifetime diagnosis of BD. Twenty-three patients (62.8%) with BD had a positive MDQ score and 47 of the 135 patients (34.8%) without BD had a negative MDQ score resulting in a weighted sensitivity of .43, a weighted specificity of .57, a positive predictive value of .21, a negative predictive value (NPV) of .80 and an area under the curve of .50. The area under the curve of the MDQ to detect BPD, APD, ADHD and any externalizing disorder ranged from .55 (APD) to .63 (ADHD). CONCLUSIONS The MDQ is not a suitable screening instrument for the detection of BD or other externalizing disorders but it could be used for ruling out the presence of BD in treatment seeking substance use disorder patients.

Abstract
Antisocial personality disorder (ASPD) and bipolar disorder are both characterized by impulsive behavior, increased incarceration or arrest, addictive disorders and suicidal behavior. These characteristics appear more severe in the combined disorders. Individuals with ASPD who also have bipolar disorder have higher rates of addictive disorders and suicidal behavior and are more impulsive, as measured by questionnaires or behavioral laboratory tests. Those with bipolar disorder who have ASPD have higher rates of addictive, criminal and suicidal behavior, earlier onset of bipolar disorder with a more recurrent and predominately manic course and increased laboratory-measured, but not questionnaire-rated, impulsivity. These characteristics may result in part from differential impulsivity mechanisms in the two disorders, with bipolar disorder driven more by excessive catecholamine sensitivity and ASPD by deficient serotonergic function.

Abstract
BACKGROUND Bipolar disorder and antisocial personality disorder (ASPD) overlap in clinical characteristics and behavioral consequences. Impulsivity is prominent in both, but there is little information on how specific mechanisms of impulsivity differentiate, bridge, or underlie the disorders. METHODS Subjects, all males, were controls (n = 46), bipolar disorder without cluster B personality disorder (n = 21), ASPD without bipolar disorder (n = 50), and bipolar disorder with ASPD (n = 16). Impulsivity measures were the Immediate Memory Task (IMT), a continuous performance test of response inhibition measuring ability to evaluate a stimulus before responding, and the Two-Choice Impulsivity Paradigm (TCIP), a choice between smaller-sooner and larger-later reward. Data were analyzed using general linear models analysis. RESULTS Subjects with bipolar disorder had fewer IMT correct detections and slower reaction times than controls. Reaction times were faster with combined diagnoses than in bipolar disorder alone. TCIP responding in either diagnosis alone resembled controls, but was more impulsive in combined disorders. These differences persisted after correction for age and education, which had significant independent effects. In combined ASPD and bipolar disorder, increased reaction speed, impulsive response bias, and reward-delay impulsivity occurred independent of substance-use disorder history. CONCLUSIONS Impulsivity was increased in the combined disorders over either disorder alone. Results were consistent with at least partially distinct mechanisms of impulsivity in ASPD and bipolar disorder. Compensatory mechanisms for impulsivity in uncomplicated ASPD or bipolar disorder appear to be compromised or lost when the disorders are combined.

Abstract
BACKGROUND Several research reports have suggested that bipolar disorder is underrecognized. Recommendations for improving the detection of bipolar disorder include the use of screening questionnaires. The Mood Disorders Questionnaire (MDQ) has been the most widely studied screening instrument for bipolar disorder, with nearly two dozen published reports on its performance. We reviewed the literature on the MDQ's performance to assess its utility as a screening instrument. METHODS We conducted a Medline search on the terms Mood Disorders Questionnaire, MDQ, screening AND bipolar disorder, and recognition AND bipolar disorder. Only studies of adults were included. RESULTS Across all studies the sensitivity of the MDQ was 61.3%; specificity, 87.5%; positive predictive value, 58.0%; and negative predictive value, 88.9%. Compared to the studies using the MDQ for psychiatric outpatients, studies using it in the general population found it to have much lower sensitivity and positive predictive value, and higher specificity and negative predictive value. The MDQ's sensitivity was higher in detecting bipolar I disorder than bipolar II disorder (66.3% vs. 38.6%). Lowering the threshold to identify cases markedly improved the MDQ's sensitivity, with only a modest reduction in specificity. Studies of the best symptom cutoff to identify cases have produced inconsistent findings. CONCLUSIONS The MDQ's performance depends upon the setting in which it is used, the threshold to identify caseness, and the subtype of bipolar disorder examined. Conceptual issues in the use of a bipolar disorder screening questionnaire are discussed, and questions are raised about the clinical value of a self-report screening scale for bipolar disorder. Based on current available evidence, routine clinical use of the MDQ cannot be recommended because of the absence of studies simultaneously examining both the potential benefits (e.g., improved detection) and costs (e.g., overdiagnosis) of screening.

Sensitivity and specificity of the mood disorder questionnaire and the bipolar spectrum diagnostic scale in Argentinean patients with mood disorders. J Affect Disord 2011; 132:445-9. [PMID: 21440943 DOI: 10.1016/j.jad.2011.03.014] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2010] [Revised: 02/07/2011] [Accepted: 03/02/2011] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To assess the sensitivity and specificity of two self-report instruments for detection of bipolarity in a sample of Argentinean patients. METHOD Spanish versions of the MDQ and the BSDS were administered over four months at 11 sites in Argentina. Diagnoses were made using DSM-IV criteria and the MINI. The study sample consisted of patients diagnosed with Bipolar Disorder (BD) Types I, II, or NOS. BDNOS diagnoses were made using extended guidelines for bipolar spectrum symptoms. Unipolar patients were used as a control group. Of 493 patients screened, 354 completed evaluation by MDQ and MINI, and 363 by BSDS and MINI. RESULTS Specificity of MDQ was 0.97 and BSDS was 0.81. MDQ sensitivity was 0.70 for bipolar type I (BD-I), 0.52 for bipolar II (BD-II) and 0.31 for bipolar not otherwise specified (BDNOS). BSDS sensitivities were 0.75, 0.70 and 0.51 respectively. LIMITATIONS This study was performed in specialized outpatient settings and thus its results are not necessarily representative for other clinical settings. There was not a systematic evaluation of comorbid psychiatric disease or test-retest reliability. CONCLUSION The local versions of the MDQ and the BSDS showed a sensitivity and specificity comparable to previous research. Our results indicate that in this sample, MDQ was more specific for BD and BSDS was more sensitive to detect BD-II and NOS. Since BD-I is more readily recognized than bipolar spectrum disorders, enhanced sensitivity of BSDS for soft bipolarity may be an advantage.

Abstract
BACKGROUND Despite the prevalent nature of postpartum depression in women with bipolar disorder, there are currently no screening instruments designed specifically for bipolar disorder in the postpartum period. METHODS Women with histories of major depressive disorder or bipolar disorder (type I or II) attending an outpatient perinatal clinic were administered the Mood Disorder Questionnaire during the first month after delivery. An experienced research coordinator, blind to the Mood Disorder Questionnaire results, conducted a face to face diagnostic interview using the Structured Clinical Interview for DSM-IV. RESULTS A total of 57 women with bipolar disorder (30 with bipolar II disorder and 27 with bipolar I disorder) and 68 women with major depressive disorder completed the Mood Disorder Questionnaire between two to four weeks after delivery. The traditional scoring criteria yielded a sensitivity of 75.44% [95%CI: 62.24%-85.87%] and a specificity of 86.76% [95%CI: 76.36%-93.77%]. The optimal cut-off score was eight or more endorsed symptoms without the supplementary questions (a sensitivity of 87.72% [95% CI: 76.32%-94.92%] and a specificity of 85.29% [95%CI: 74.61%-92.72%]). CONCLUSIONS The Mood Disorder Questionnaire with alternate scoring is a useful screening instrument for bipolar disorder in the postpartum period.

Abstract
OBJECTIVE Criminal behavior in bipolar disorder may be related to substance use disorders, personality disorders, or other comorbidities potentially related to impulsivity. We investigated relationships among impulsivity, antisocial personality disorder (ASPD) or borderline personality disorder symptoms, substance use disorder, course of illness, and history of criminal behavior in bipolar disorder. METHODS A total of 112 subjects with bipolar disorder were recruited from the community. Diagnosis was by Structured Clinical Interview for DSM-IV (SCID-I and SCID-II); psychiatric symptom assessment by the Change version of the Schedule for Affective Disorders and Schizophrenia (SADS-C); severity of Axis II symptoms by ASPD and borderline personality disorder SCID-II symptoms; and impulsivity by questionnaire and response inhibition measures. RESULTS A total of 29 subjects self-reported histories of criminal conviction. Compared to other subjects, those with convictions had more ASPD symptoms, less education, more substance use disorder, more suicide attempt history, and a more recurrent course with propensity toward mania. They had increased impulsivity as reflected by impaired response inhibition, but did not differ in questionnaire-measured impulsivity. On logit analysis, impaired response inhibition and ASPD symptoms, but not substance use disorder, were significantly associated with criminal history. Subjects convicted for violent crimes were not more impulsive than those convicted for nonviolent crimes. CONCLUSIONS In this community sample, a self-reported history of criminal behavior is related to ASPD symptoms, a recurrent and predominately manic course of illness, and impaired response inhibition in bipolar disorder, independent of current clinical state.

Abstract
OBJECTIVES Recent research has suggested that bipolar disorder, when defined to include milder variants such as bipolar II disorder and bipolar disorder not otherwise specified (NOS), is more prevalent than had been previously reported and often underrecognized. Recommendations for improving the detection of bipolar disorder have included careful clinical evaluations inquiring about a history of mania and hypomania and the use of screening questionnaires. The Bipolar Spectrum Diagnostic Scale (BSDS) was designed to be particularly sensitive to the milder variants of bipolar disorder. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we examined the operating characteristics of the BSDS in a large sample of psychiatric outpatients presenting for treatment. METHODS A total of 1,100 psychiatric outpatients were interviewed with the Structured Clinical Interview for DSM-IV and asked to complete the BSDS. Missing data on the BSDS reduced the sample size to 961, approximately 10% (n = 90) of whom were diagnosed with bipolar disorder. RESULTS The sensitivity of the BSDS was similar for bipolar I disorder, bipolar II disorder, and bipolar disorder NOS/cyclothymia. A receiver operating curve (ROC) analysis indicated that cutoffs of 11 and 12 maximized the sum of sensitivity and specificity for the entire group of patients with bipolar disorder (area under curve = 0.80, p < 0.001). The cutoff point associated with 90% sensitivity for the entire sample of patients with bipolar disorder was 8. At this cutoff the specificity of the scale was 51.1% and positive predictive value was 16.0%. We compared the patients with and without bipolar disorder on each of the BSDS symptom items. The odds ratios were higher for the items assessing hypomanic/manic symptoms than items assessing depressive symptoms. We therefore examined the performance of a subscale composed only of the hypomania/mania items. The area under the curve in the ROC analysis was nearly identical to that of the entire scale (0.81, p < 0.001). CONCLUSIONS With its high negative predictive value, the BSDS was excellent at ruling out a diagnosis of bipolar disorder; however, the low positive predictive value indicates that it is not good at ruling in the diagnosis. These data raise questions about the use of the BSDS as a screening measure in routine clinical psychiatric practice.

Abstract
Abstract Objective. Comorbid mental illness amongst methadone maintenance therapy clients may be common and screening may be warranted. The Mood Disorders Questionnaire (MDQ) is a screening tool for bipolar disorder that has been validated in other treatment settings. Its utility for patients with substance use disorders is assessed in this study. Methods. Clients of a methadone maintenance program were invited to complete the MDQ when they attended a public Drug and Alcohol Service for their regular scheduled appointments. Information about their history of substance use was also collected. Results. Eighty clients (43 females, 37 males) aged 35 ± 8.0 years (mean ± SD) participated in the study. Seventy-four clients completed the MDQ of which 36 (48.6%) obtained a positive screen. A check of client files suggested that only three of the 74 participants had a current working diagnosis of bipolar disorder. These three participants had screened positive on the MDQ. Conclusions. There was a high prevalence of manic symptoms reported by participants, suggesting that screening for bipolar disorder in this population may be warranted. However, there is a risk of false positives with the MDQ, as it does not clearly differentiate between symptoms of mania and drug intoxication.

Abstract
Bipolar disorder is a significant mental health problem among perinatal women; however, little attention has been devoted to methods of screening for bipolar disorder during this phase of women's life cycle. There is a need for reliable and valid screening instruments for perinatal women. This paper presents a review of 11 self-report measures used to screen bipolar disorder in the general population and discusses their applicability to screening among perinatal women. Published psychometric data, including reliability, sensitivity, specificity, and positive predictive value of each self-report instrument, is presented and critiqued. We make recommendations for screening in clinical practice and highlights priorities for future research. The need for more research in this area is emphasized.

Abstract
OBJECTIVE We investigated trait impulsivity in bipolar disorder and antisocial personality disorder (ASPD) with respect to severity and course of illness. METHOD Subjects included 78 controls, 34 ASPD, 61 bipolar disorder without Axis II disorder, and 24 bipolar disorder with ASPD, by Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) (SCID-I and -II). Data were analyzed using general linear model and probit analysis. RESULTS Barratt Impulsiveness Scale (BIS-11) scores were higher in ASPD (effect sizes 0.5-0.8) or bipolar disorder (effect size 1.45) than in controls. Subjects with both had more suicide attempts and previous episodes than bipolar disorder alone, and more substance-use disorders and suicide attempts than ASPD alone. BIS-11 scores were not related to severity of crimes. CONCLUSION Impulsivity was higher in bipolar disorder with or without ASPD than in ASPD alone, and higher in ASPD than in controls. Adverse effects of bipolar disorder in ASPD, but not of ASPD in bipolar disorder, were accounted for by increased impulsivity.

Abstract
BACKGROUND The Mood Disorder Questionnaire (MDQ) was designed as a screening questionnaire for bipolar disorder. Previous research has raised questions about the suitability of the MDQ structure for screening for bipolar II disorder. This study investigated the optimal sensitivity and specificity cut-off thresholds for the MDQ in bipolar I and bipolar II patients in a UK sample. METHODS The MDQ was administered to patients before attending a tertiary mood disorders clinic. Diagnostic interviews were used to determine DSM-IV diagnoses and these were used as the gold standard against which to investigate the performance of the MDQ. RESULTS 54 patients with bipolar spectrum disorder and 73 patients with unipolar depressive disorder completed the MDQ. With the original scoring criteria (symptoms and supplementary questions) the sensitivity for bipolar disorder was 0.76 (bipolar I disorder 0.83, bipolar II disorder 0.67) with specificity 0.86. The optimal cut-off score in the current sample was a score of 9 or more endorsed symptoms without applying the supplementary questions (sensitivity of 0.90 and 0.88 for bipolar I and bipolar II groups respectively with a specificity of 0.90). LIMITATIONS The sample was drawn from a tertiary mood disorders clinic. CONCLUSIONS The MDQ appears to be a useful screening tool for bipolar spectrum disorder in UK psychiatric practice with sensitivity for bipolar II disorder improved by dropping the supplementary sections. Further investigation of the optimal cut-off scores of the MDQ is needed to determine its utility in non-specialist and community based samples.
