Psychotic symptoms during bipolar depressive episodes and suicidal ideation.

BACKGROUND: Psychotic symptoms during bipolar depressive episodes, especially in outpatients, are under recognized and studied by clinicians and researchers. We examined the relationship between psychotic symptoms during a depressive episode and suicidal ideation in bipolar patients. METHODS: Participants (N = 351) were adult, depressed outpatients with bipolar disorder (BD) in a comparative effectiveness study of quetiapine versus lithium. Psychotic symptoms were assessed via Bipolar Inventory of Signs and Symptoms Scale (BISS) and depressive episodes via Mini-International Neuropsychiatric Interview (MINI). Because only 4.84% (N = 17) endorsed psychotic symptoms, we performed iterative multivariate matching with non-psychotic participants. On every matched population, a multiple regression analysis examined whether psychotic symptoms were associated with suicidal ideation, via the Concise Health Risk Taking scale (CHRT-12). RESULTS: Averaged across the 50 matched populations, current psychotic symptoms predicted active suicidal ideation on the CHRT, but not a passive propensity toward suicide or total CHRT scores, after adjusting for common correlates of suicidality (e.g., previous suicidal behavior) (ß=0.59, p=.01, R2= 0.41). LIMITATIONS: Our study was limited by three factors. First, the generalizability of our study was limited as the sample included only outpatients. Next, the analysis was cross-sectional and does not allow for causal interpretation. Lastly, our study lacked information regarding the content and mood congruency of participants' psychosis. CONCLUSION: While a small proportion of BD outpatients had current symptoms of psychosis during their depressive episode, those who did were more likely to endorse active suicidal thoughts, including suicide methods and plans.

An evaluation of suicidal risk in bipolar patients with comorbid posttraumatic stress disorder.

BACKGROUND: While bipolar disorder (BD) and posttraumatic stress disorder (PTSD) frequently co-occur and individually have a higher risk of suicide compared to the general population, few studies have examined the impact of comorbid PTSD on suicidal ideation in patients with BD. METHODS: We analyzed baseline data from the Clinical and Health Outcomes Initiative in Comparative Effectiveness for bipolar disorder study (Bipolar CHOICE), a 6-month, pharmacological comparative effectiveness trial of individuals with BD. Bipolar CHOICE enrolled 482 individuals. A hierarchical multiple regression analysis assessed whether comorbid PTSD was associated with increased suicidal ideation as assessed by the Concise Health Risk Tracking Scale (CHRT) total and factor scores, while controlling for common correlates of suicidal ideation in this population such as a current major depressive episode, comorbid anxiety disorders, severity of illness and previous suicide attempts. RESULTS: Consistent with our hypothesis, diagnosis of comorbid PTSD was a significant predictor of the CHRT total score (ß=2.59, p=.03). Comorbid PTSD was also a significant predictor of the CHRT propensity factor (ß=2.32, adjusted p=.04), but was not a significant predictor of the active suicidal thoughts factor. Additionally, all participants with comorbid PTSD (N = 58) endorsed current suicidal ideation (p=.005) and were more likely to have had a previous suicide attempt (p<.001) compared to those without PTSD. LIMITATIONS: Generalizability beyond outpatient settings is limited, mixed affective states were not assessed, and analyses were cross-sectional. CONCLUSIONS: Patients have an increased risk of suicidal ideation when PTSD is comorbid with BD.

Reliability and validity of the Haitian Creole PHQ-9.

BACKGROUND: There is limited information on depression in Haitians and this is partly attributable to the absence of culturally and linguistically adapted measures for depression. OBJECTIVE: To perform a psychometric evaluation of the Haitian-Creole version of the PHQ-9 administered to men who have sex with men (MSM) in the Republic of Haiti. DESIGN: This study uses a cross-sectional design and data are from the Integrated Behavioral and Biological HIV Survey (IBBS) for MSM in Haiti. PARTICIPANTS: Inclusion criteria required that participants be male, ≥ 18 years, report sexual relations with a male partner in the last 12 months, and lived in Haiti during the past 3 months. Respondent Driven Sampling was used for participant recruitment. MAIN MEASURES: A structured questionnaire was verbally administered in Haitian-Creole capturing information on sociodemographics, sexual behaviors, human immunodeficiency virus (HIV) status and depressive symptomatology using the PHQ-9. Psychometric analyses of the translated PHQ-9 assessed unidimensionality, factor structure, reliability, construct validity, and differential item functioning (DIF) across subgroups (age, educational level, sexual orientation and HIV status). KEY RESULTS: In a study population of 1,028 MSM, the Haitian-Creole version of the PHQ-9 is unidimensional, has moderately high internal consistency reliability (α = 0.78), and shows evidence of construct validity where HIV-positive subjects have greater depression (p = 0.002). There is no evidence of DIF across age, education, sexual orientation or HIV status. HIV-positive MSM are twice as likely to screen positive for moderately severe and severe depressive symptoms compared to their HIV-negative counterparts. CONCLUSIONS: There is strong evidence for the psychometric adequacy of the translated PHQ-9 screening tool as a measure of depression with MSM in Haiti. Future research is necessary to examine the predictive validity of depression for subsequent health behaviors or clinical outcomes among Haitian MSM.

The integration of measurement and management for the treatment of bipolar disorder: a STEP-BD model of collaborative care in psychiatry.

Patients with bipolar disorder are among the most challenging to treat. These patients frequently present with complex mood and other symptoms that change over time, complex psychiatric and medical comorbid conditions, and multiple medications. Clinicians rarely systematically assess or measure all of these factors and instead rely on memory and general impressions. It is imperative that clinicians systematically track and monitor these relevant variables to ensure treatment decisions are based on precise clinical data. By integrating measurement and management, clinicians and patients can collaborate to assess the effectiveness of treatments and to make joint decisions about critical points at which to adjust treatment. This method was shown to be successful in the National Institute of Mental Health (NIMH) Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD).

Treating Haitian patients: key cultural aspects.

The Haitian community in the United States is growing steadily. They make up a significant portion of many cities. As a group, Haitian immigrants are a challenge to mental health professionals. Their view and concepts of the world are unique. Non-Haitian clinicians need to be knowledgeable of the culture in order to provide competent care. The goal of this article is to help clinicians understand aspects of Haitian culture that will facilitate mental health treatment. A historical perspective is offered since the history of Haiti has shaped society, families and therefore individuals. The role of the supernatural is addressed to provide a better understanding of the Haitian psyche. The political and economic climate in Haiti has led to a significant increase in the number of Haitians migrating to the United States. Haitians are faced with the challenge of adapting to a new culture; they experience stress and become vulnerable to mental illness. As a result, there is increasing demand for mental health services. This article highlights aspects of Haitian culture relevant to mental health clinicians. It provides an overview of Haitians' attitudes toward mental health and the utilization of psychotherapy. Concepts relevant to Voodoo beliefs and practices are discussed since these beliefs can shape attitudes, and compliance with treatment. Recommendations for engaging and maintaining Haitian clients in psychotherapy are made. Case vignettes are provided for illustration.
