RESUMEN

Biomarkers that can differentiate between psychiatric disorders with and without suicidal behavior history from each other and from healthy volunteers may explain part of the pathogenesis of suicidal behavior. We conducted the hitherto largest meta-analysis comparing immune biomarkers between subjects with and without suicide attempt history or death by suicide. The study protocol was registered with PROSPERO, CRD42020212841. Standardized mean differences (SMD) were pooled with random-effects models. Heterogeneity between studies was assessed with the I2-statistic and publication bias was evaluated by the Egger test and funnel plots. Data were based on 36 studies including 2679 persons with suicidal behaviors and 6839 comparison subjects, and four immune-related biomarkers (CRP, IL-6, TNF-α and IL-1ß). Suicidal behavior was associated with higher CRP blood levels compared with: healthy controls (SMD [95%CI] = 1.42[0.85-1.98]); patients with depression alone (SMD [95%CI] = 1.23[0.20-2.26]); and patients with any psychiatric disorders (SMD [95%CI] = 0.39[0.22-0.55]). IL-6 blood level was higher in patients with suicidal behaviors compared with healthy controls (SMD [95%CI] = 1.13[0.45-1.82]) and when compared with psychiatric patients without suicidal behaviors (SMD [95%CI] = 0.22 [0.11-0.33]). Meta-regression and subgroup analyses revealed that increased CRP in suicidal behavior is primarily driven by recent suicidal behavior. These results implicate the immune system and inflammatory response in suicidal behavior independent of a relationship to major psychiatric disorders, and that these biological measures are predominantly state-dependent markers. Future studies are needed to determine the cause-and-effect relationship of these immune system biomarkers with suicidal behavior, and their potential predictive properties.

RESUMEN

BACKGROUND: Between 25% and 50% of patients suffering from treatment-resistant schizophrenia fail to achieve a clinical response with clozapine. The rapid identification and treatment of this subgroup of patients represents a challenge for healthcare practice. AIMS: To evaluate the relationship between metabolic alterations and the clinical response to clozapine. METHODS: A multicenter, observational, case-control study was performed. Patients diagnosed with schizophrenia treated with clozapine were eligible (minimum dose 400 mg/d for at least 8 weeks and/or clozapine plasma levels ⩾ 350 µg/mL). According to the Positive and Negative Syndrome Scale (PANSS) total score, patients were classified as clozapine-responsive (CR) (<80 points) or clozapine non-responsive (CNR) (⩾80 points). Groups were compared based on demographic and treatment-related characteristics, together with body mass index (BMI), waist circumference, insulin, leptin, and C-reactive protein plasma levels. Plasma levels of clozapine and its main metabolite, nor-clozapine, were measured in all the participants. In addition, the potential relationship between PANSS scores and leptin or insulin plasma levels was assessed. RESULTS: A total of 46 patients were included: 25 CR and 21 CNR. BMI and waist circumference, fasting insulin and leptin plasma levels were lower in the CNR group, while C-reactive protein was not different. Moreover, significant negative correlations were observed between PANSS positive and general psychopathology subscores, on one hand, and insulin and leptin plasma levels, on the other hand, as well as between PANSS negative subscores and leptin plasma levels. CONCLUSIONS: Our results suggest that the lack of metabolic effect induced by clozapine is associated with the lack of clinical response.

RESUMEN

The seven-item Hospital Anxiety and Depression Scale Depression subscale (HADS-D) and the total score of the 14-item HADS (HADS-T) are both used for major depression screening. Compared to the HADS-D, the HADS-T includes anxiety items and requires more time to complete. We compared the screening accuracy of the HADS-D and HADS-T for major depression detection. We conducted an individual participant data meta-analysis and fit bivariate random effects models to assess diagnostic accuracy among participants with both HADS-D and HADS-T scores. We identified optimal cutoffs, estimated sensitivity and specificity with 95% confidence intervals, and compared screening accuracy across paired cutoffs via two-stage and individual-level models. We used a 0.05 equivalence margin to assess equivalency in sensitivity and specificity. 20,700 participants (2,285 major depression cases) from 98 studies were included. Cutoffs of ≥7 for the HADS-D (sensitivity 0.79 [0.75, 0.83], specificity 0.78 [0.75, 0.80]) and ≥15 for the HADS-T (sensitivity 0.79 [0.76, 0.82], specificity 0.81 [0.78, 0.83]) minimized the distance to the top-left corner of the receiver operating characteristic curve. Across all sets of paired cutoffs evaluated, differences of sensitivity between HADS-T and HADS-D ranged from -0.05 to 0.01 (0.00 at paired optimal cutoffs), and differences of specificity were within 0.03 for all cutoffs (0.02-0.03). The pattern was similar among outpatients, although the HADS-T was slightly (not nonequivalently) more specific among inpatients. The accuracy of HADS-T was equivalent to the HADS-D for detecting major depression. In most settings, the shorter HADS-D would be preferred.

RESUMEN

PURPOSE: This study explores postpartum depression (PPD) in women who screened negative in mid-pregnancy to assess the impact of the peripartum period on the development of depressive symptoms. METHODS: A prospective cohort study was carried out in two facilities in Argentina. The Edinburgh postnatal depression scale (EPDS) scale was applied to pregnant women between weeks 20-24 gestation, and those screening negative (<10) were included in the cohort. Participants were followed up until the 4th week postpartum, when the EPDS was repeated. If positive, a semi-structured clinical interview was applied (MINI) to define the diagnosis. RESULTS: A total of 112 pregnant women were eligible for the follow-up. At the 4th week postpartum, 14 women (12.5%, CI 95% 7.0; 20.1) screened positive using a cutoff point of 10 or more in the EPDS. Of those screened positive in the EPDS, two participants (1.8%, CI 95% 0.2-6.3) had a Major Depressive Disorder. Newborn admission to the Intensive Care Unit, hospitalization of the newborn after discharge, abuse during childbirth, and lack of company during labor were identified as peripartum risk factors. CONCLUSIONS: This study reinforces the relevance of women and newborn mental health care during the hospitalization process surrounding peripartum. The women and newborn hospitalization process should be better explored to understand the contribution to PPD and design and test strategies to alleviate the impact of maternal depression.

RESUMEN

The present study was aim to evaluate the acceptability and preliminary effectiveness of a mobile-health application, CALMA, based on dialectical behavioral therapy skills. CALMA was proposed as an adjunct to therapy for the reduction of non-suicidal and suicidal self-injury behaviors. A parallel design was used to compare the intervention group (DBT + CALMA) and the comparison group (DBT). Patients were randomized based on their groups following a randomized cluster design. After treatment, patients completed a follow-up assessment four weeks later. Each cluster was represented by a different DBT Skills Training Group offered weekly at FORO Foundation for Mental Health. Six DBT Skills Training groups were randomized to the intervention or comparison group. Twenty-one individuals met inclusion criteria and eighteen were included in the analysis. Acceptability was measured with the User Experience Questionnaire short version (UEQ-s) and preliminary efficacy with the Self-injurious thoughts and behaviors interview (SITBI). CALMA shows good acceptability to be used as an adjunct to therapy specific to the reduction of suicidal and non-suicidal self-directed violence. Evidence for preliminary efficacy included a high probability of decreased in more behaviors evaluated with the SITBI pre- and post-intervention for the group that received CALMA as compared to the comparison group. Our study provides initial evidence for the effectiveness and acceptability of CALMA. Future studies scaling up this intervention in a larger number of participants are necessary. CALMA may be especially useful in low and middle-income Latin American countries to improve access to evidence-based interventions openly available in Spanish and free to download.HighlightsCALMA is a DBT-based app aimed to reduce non-suicidal and suicidal self-directed violence.The app showed good acceptability by usersA high probability of decrease in suicidal ideation, suicidal plan, suicidal gesture, thoughts about NSSI and NSSI pre- and post-intervention was observed.

RESUMEN

The objectives of this cross-sectional study were to estimate the prevalence of depressive symptoms and affective disorders during pregnancy in a maternity hospital in Argentina and to explore potential risk factors. Symptoms of depression were measured with the Edinburgh Postnatal Depression Scale (EPDS), and the Mini International Neuropsychiatric Interview (MINI) for diagnosis at mid-pregnancy. 50.7%, 95% CI: 43.7; 57.8 screened positive using a score ≥ 10 and 23% of pregnant women were diagnosed with affective disorders, 11% unipolar, and 12% bipolar. Personal and family depression history were main risk factors. It is advised to routinely screen for depression during pregnancy.

RESUMEN

Polyunsaturated fatty acids (PUFAs) and cholesterol are lipids implicated in suicide risk. We prospectively studied plasma glycerophospholipid PUFAs and cholesterol as putative predictors of suicide attempts. In a multicenter cohort study, we enrolled 123 patients admitted to the emergency department (ED) for suicidal ideation or suicide attempt. Clinical assessments were performed, with follow-up telephone evaluations 6, 12, 18, and 24 months later. Blood samples were obtained in the ED and assayed for PUFAs. Using survival analysis, suicide events were not predicted by eicosapentaenoic acid (EPA, HR: -0.83, 95%CI: 0.39-1.76, p = 0.621) or docosahexaenoic acid (DHA, HR: -0.60, 95%CI: 0.19-1.86, p = 0.371). However, higher arachidonic acid (AA) was a trend for a protective factor (HR=0.30, 95%CI: 0.08-1.08, p = 0.065) in the entire trans-diagnostic sample. This protective effect was significant in all participants with a prior suicide attempt history (n = 85; HR=0.16, 95%CI: 0.04-0.67, p = 0.012), and in the subgroup of attempters with major depressive disorder (MDD; n = 55, HR=0.15, 95%CI:0.03-0.76, p = 0.002). Total LDL- and HDL-cholesterol did not predict subsequent suicide events. AA, but not DHA or EPA, positively correlated with baseline depression severity in MDD patients (r = 0.3, p = 0.006). Contrary to our hypothesis that low n-3 PUFA levels would create risk, we found that while higher AA was associated with greater depression severity at baseline, low AA unexpectedly predicted subsequent suicide attempts, the more so in higher-risk patients. Although surprising, this result agrees with a minority of reports concerning n-6 PUFAs and may represent complex interactions with sample characteristics.

RESUMEN

The current study aims to compare the prevalence of adverse childhood experiences (ACEs) between patients with schizophrenia and non-psychiatric control group, and to analyze the association of having suffered multiple ACEs with clinical symptoms of schizophrenia and suicidal behavior. A multicenter, cross-sectional study was conducted across three facilities in Buenos Aires, Argentina. One-hundred patients with schizophrenia and 50 healthy subjects were assessed with the Adverse Childhood Experiences questionnaire (ACE-Q), the Positive and Negative Syndrome Scale (PANSS), and the Columbia-Suicide Severity Rating Scale (C-SSRS). We observed that the prevalence of at least one ACE in schizophrenic patients was almost double in comparison with the non-psychiatric control group. Multiple ACEs were associated with persistent auditory hallucinations and lower negative symptoms in both sexes. Higher frequency of death ideation and a higher number of suicide attempts were reported among women. The strength of this study is the possibility of comparing the presence of ACEs between schizophrenic patients and non-psychiatric control using the same questionnaire in an under-reported sample of low socio-economic patients assisted in public hospitals. A limitation is that the history of ACEs relied on the retrospective assessment of childhood experiences, and adults could over-report ACEs because of recall bias.

RESUMEN

OBJECTIVE: Two previous individual participant data meta-analyses (IPDMAs) found that different diagnostic interviews classify different proportions of people as having major depression overall or by symptom levels. We compared the odds of major depression classification across diagnostic interviews among studies that administered the Depression subscale of the Hospital Anxiety and Depression Scale (HADS-D). METHODS: Data accrued for an IPDMA on HADS-D diagnostic accuracy were analysed. We fit binomial generalized linear mixed models to compare odds of major depression classification for the Structured Clinical Interview for DSM (SCID), Composite International Diagnostic Interview (CIDI), and Mini International Neuropsychiatric Interview (MINI), controlling for HADS-D scores and participant characteristics with and without an interaction term between interview and HADS-D scores. RESULTS: There were 15,856 participants (1942 [12%] with major depression) from 73 studies, including 15,335 (97%) non-psychiatric medical patients, 164 (1%) partners of medical patients, and 357 (2%) healthy adults. The MINI (27 studies, 7345 participants, 1066 major depression cases) classified participants as having major depression more often than the CIDI (10 studies, 3023 participants, 269 cases) (adjusted odds ratio [aOR] = 1.70 (0.84, 3.43)) and the semi-structured SCID (36 studies, 5488 participants, 607 cases) (aOR = 1.52 (1.01, 2.30)). The odds ratio for major depression classification with the CIDI was less likely to increase as HADS-D scores increased than for the SCID (interaction aOR = 0.92 (0.88, 0.96)). CONCLUSION: Compared to the SCID, the MINI may diagnose more participants as having major depression, and the CIDI may be less responsive to symptom severity.

RESUMEN

The current study aimed to compare suicide-related variables as a function of 1) family history of suicidal behavior and 2) child sexual abuse among patients hospitalized for a suicide attempt or active suicidal ideation. Family history of suicidal behavior and child sexual abuse were examined independently and in combination as a diathesis for a high-risk suicidal phenotype. A multicenter cross-sectional study was designed to compare data obtained from 292 patients hospitalized for suicidal behavior. Demographic and clinical variables were compared among Group 1 (patients who reported both family history of suicidal behavior and child sexual abuse), Group 2 (patients who reported only family history of suicidal behavior), Group 3 (patients who reported only child sexual abuse), and Group 4 (patients who did not report family history of suicidal behavior or childhood sexual abuse). A multinomial logistic regression was used to examine suicide-related variables associated with each group and to compare differences between groups. Group 1 and 3 endorsed a higher number of previous suicide attempts and were more likely to be younger at the first suicide attempt compared to Group 4. Group differences remained after adjustment in a multinomial regression model. The current findings suggest that child sexual abuse may be more strongly related to suicide risk among high risk patients than family history of suicidal behavior.

RESUMEN

Prior studies have suggest that religiosity mitigates symptoms of depression. However, population-based data in South America are limited. This study determines the prevalence of religiosity and explores its association with depression in four cities of the Southern cone of Latin-America. In the CESCAS I study 7524 participants aged between 35 and 74 years old were recruited between 2011 and 2012 from randomly selected samples in 4 cities (Bariloche and Marcos Paz, Argentina; Temuco, Chile; and Pando-Barros Blancos, Uruguay). Religiosity was assessed with a questionnaire from the Hispanic Community Health Study/Study of Latinos. Two dimensions were used: 1) recognition as belonging to a religion; and 2) frequency of participation in religious activities. Depression was measured using the PHQ-9. Prevalence of religiosity was described by sociodemographic characteristics. Association between religiosity and depression was examined through logistic regression models controlling for sex, age and other potential confounders. Weekly religious activities were reported by 32.3% (95% CI: 30.1, 33.6) of participants. Prevalence of major depressive episode (MDE) was 14.6% (95% CI: 13.6, 15.6). After controlling for confounders, older women (≥65 years) who reported religious affiliation had 70% lower likelihood of having MDE (OR: 0.3; 95% CI, 0.1, 0.8). Moreover, in this group, women participating in religious activities more than once per week compared with "never" had 50% lower likelihood of having a MDE (OR: 0.5; 95% CI: 0.3, 0.9). No association between religious activities and depression was found in men. Religiosity is highly prevalent among adults in four cities of South America. Our study found an inverse association between religiosity and depression only in women, stronger in olders. Although longitudinal studies are necessary to determine the true nature of these relationships, religiosity may be a relevant factor that health care providers could take into account when exploring depression in their patients.

RESUMEN

BACKGROUND: To meet the goal of preventing suicide the most important thing is to know the risk factors of suicidal behavior and understand their interaction. AIMS: The current study aims to evaluate prospective predictors and the interaction between factors for suicide and suicide re-attempts in high-risk, suicidal patients during a 24 month prospective follow-up period. METHODS: A multicenter prospective cohort study was designed to compare data obtained from 324 patients admitted to the emergency department for current suicidal ideation or a recent suicide attempt. Participants were clinically evaluated at baseline and follow-up every 6 months to assess any unfavorable events (suicide or a suicide attempt). To estimate the rate of unfavorable events, the Kaplan-Meier method was used and Cox Proportional Hazards Regression Model was employed to examine predictors of suicide and suicide reattempt. RESULTS: The incidence of a new suicide attempt was 26,000 events/100,000 persons-years. The incidence of death by suicide was 1110 events/100,000 person-year. The most reliable predictors of unfavorable events were being women, previous suicide attempts, younger age, and childhood sexual abuse. Findings revealed an interaction between childhood sexual abuse and low psychosocial functioning that increased the risk of an unfavorable event. CONCLUSION: The risk of suicide re-attempts and suicide in the current 2-year follow-up was high. There was an interaction between low psychosocial functioning and childhood sexual abuse. This evidence should be taken into account for the evaluation and planning of preventive strategies.

RESUMEN

INTRODUCTION: To examine the relationship between suicidal ideation (SI) and cardiovascular disease (CVD) in the general adult population of four cities in the Southern Cone of Latin America (Argentina, Uruguay, Chile) and the role that depression, stressful life events (SLEs) and physical functional impairment may play in this association. METHODS: A population-based cross-sectional study was conducted among 7524 adults between 35 and 74 years old, randomly selected. History of CVD included acute myocardial infarction, stroke and central or peripheral revascularization. SI in the past two weeks was measured using the last item of the Patient Health Questionnaire (PHQ-9), quality of life was assessed with the 12-item Short Form Survey (SF-12), and having experience of a SLE was determined by asking participants whether they had experienced at least one of a list of events in the past year. Multiple logistic regression was used to examine the association between SI and CVD overall and by sex. RESULTS: The prevalence of SI was 8.3% (95% CI = 7.5, 9.0) and twice as high among women than men (11.1% vs. 5.1%). History of CVD was associated with almost twice the odds of SI (OR = 1.9, 95% CI = 1.5, 2.4). This association remained strong and significant after adjusting for potential confounders (OR = 1.8, 95% CI = 1.2, 2.7). Three additional models were tested to further adjust for depression severity, functional impairment, and SLEs separately. Adjustment for depression severity yielded no association between CVD and SI (OR = 1.1, 95% CI = 0.6, 1.7), adjustment for functional impairment yielded a marginal statistically significant association (OR = 1.5; 95% CI = 1.0, 2.4) and adjustment for SLE didn't modify either the magnitude or the statistical significance of the association. CONCLUSIONS: There is a significant association between SI and CVD, particularly among women, which may be driven, at least in part, by depression and physical functional impairment.

RESUMEN

OBJECTIVE: A suicide attempt is an established risk factor for subsequent suicide attempts and suicide. Nonetheless, the prediction of future suicidal behavior is poor. The lethality of previous suicidal behavior may be informative to better understand future suicide risk among patients hospitalized for suicidal thoughts and behavior. The current study examined whether the lethality of patients' index (most recent suicidal episode at hospitalization), first, and worst suicidal episode predicts the lethality of one's most lethal suicide attempt during a 2-year follow-up period. METHOD: A total of 98 patients hospitalized at an emergency department for high suicide risk (i.e., acute suicidal ideation or a suicide attempt) were included in the study. RESULTS: Results indicated that the lethality of the index suicidal episode predicted the lethality of the worst suicide attempt during a 2-year follow-up period. CONCLUSIONS: These findings extend a growing literature examining risk factors that influence the progression toward high lethality suicidal behavior.

RESUMEN

OBJECTIVE: The serotonin-transporter-linked polymorphic region (5-HTTLPR) polymorphisms are associated with suicidal behavior; however, prospective studies are scarce. Herein we aim to determine if 5-HTTLPR polymorphisms predict risk of short-term suicide reattempt in a high-risk suicidal sample. We also explore possible mediators or moderators of this relationship. METHODS: A multicenter prospective cohort study was designed to compare data obtained form 136 patients admitted to the emergency department for current suicidal ideation or a recent suicide attempt. Subjects were clinically evaluated, genotyped, and monitored for a new suicide attempt for 6 months. RESULTS: At 6 months of follow up, 21% of the subjects had a new suicide attempt. The frequency of L-allele and L-carrier was higher in reattempters when compared with non-reattempters (55.8% vs. 35.4%, p =  0.01 and 76.9% vs. 54.2%, p = 0.04, respectively). Reattempters also differ from non-reattempters patients with respect to age, history of previous suicide attempts, and age of onset of suicidal behavior. The logistic regression model showed that L-carriers had an odds ratio of 2.8 (95% CI: 1.0-7.6) for reattempts when compared to SS genotype. The adjusted model indicates that this association is not mediated or moderated by impulsivity. CONCLUSION: The 5-HTTLPR polymorphisms predicted short-term risk of suicidal reattempt independently of age and sex. L-carriers have almost three times more risk of relapse when compared with SS carriers.

RESUMEN

Suicide and nonfatal suicidal behaviors are major causes of mortality and morbidity worldwide. Variability in rates of suicide and suicidal behaviors within and between countries has been attributed to population and individual risk factors, including economic status and cultural differences, both of which can have suicide risk effects mediated through a variety of factors, of which perhaps the least understood is the role of diet. We therefore review the scientific literature concerning two major dietary lipid classes, cholesterol and polyunsaturated fatty acids (PUFAs), that have been associated with higher risk of suicide attempts and suicide. We consider potential mechanistic intermediates including serotonin transporters and receptors, toll-like receptors (TLRs), nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB), and peroxisome proliferator activated receptors (PPARs). Based on this review, we describe a theoretical model linking cholesterol and PUFA status to suicide risk, taking into account the effects of cholesterol-lowering interventions on PUFA balance, membrane lipid microdomains (rafts) as a nexus of interaction between cholesterol and omega-3 PUFAs, and downstream effects on serotonergic neurotransmission and specific inflammatory pathways.

RESUMEN

During the last 15 years, the suicide rate has doubled among individuals aged between 15 and 24 years in Argentina. This marks the need to develop new strategies for suicide prevention among this age group. Smartphones have become a good platform to provide evidence-based interventions universally, inexpensively and quickly. In particular, there is a high penetration of these devices locally and an acceptance of this technology among young people. In this article, the theoretical basis, as well as the technical design, and safety aspects used for the development of CALMA are described. CALMA is the frst Spanish tool-based mobile app for smartphones, which interacts with the user providing tools based on dialectical behavioral therapy (DBT) for the management of crisis situations and thus preventing suicide among adolescents and young people. CALMA also provides information, promoting activities aimed to reduce one's vulnerability in order to prevent new crises, and psychoeducational content about suicide and its prevention. The app was designed for teenagers and young people. It is available for free in Argentina since May 2017 and works with Android and iOS.

RESUMEN

PURPOSE: to estimate the prevalence of depression at 4-week postpartum using the Edinburgh postpartum Depression Scale (EPDS) in women who delivered in a public maternity hospital in Argentina. METHODS: This prospective cohort study was carried out from March to August 2016 in northwest Argentina. Eligibility included delivering a singleton live birth 28 weeks of gestational age or over, 18 years or older and resided within 1h from the maternity hospital. Women were excluded if they or their newborn were in the intensive care unit. We defined a positive screening as an EPDS score of 10 or higher or a positive response to item 10, which indicates thoughts of self-harm. RESULTS: A total of 587 women were enrolled and 539 women completed the home visit interview and the EPDS. A total of 167 (31.0%, 95% CI 27.1-35.1) mothers screened positive in the EPDS using a score ≥ 10 and 99 (18.4%, 95% CI 15.1-21.6%) using a score ≥ 13, which indicate increased severity of depressive symptoms. In both cases, the 23 (4.3%) women that responded as having thoughts of self-harm were included. CONCLUSION: Nearly a third of women who participated had depressive symptoms at four weeks postpartum in a public hospital in Tucumán, Argentina. Socio-demographic, particularly personal psychiatric history, factors and social and cultural influences can impact results. Our results highlight the need for improved screening and better diagnostic tool for women with postpartum depression in Argentina and to investigate the impact of postpartum depressive symptoms on women's health and their families.

RESUMEN

The current study was interested in exploring the clinical factors related to mental and physical health-related quality of life among patients hospitalized for suicidal behavior. A multicenter cross-sectional study was designed to compare data obtained form 246 patients hospitalized for suicide behavior. Results suggest that mental health-related quality of life was negatively associated with hopelessness while physical health-related quality of life was negatively associated with age, medical disease and the number of previous suicide attempts and positively associated with employment. Findings are discussed in the context of theoretical evidence and clinical implications.

RESUMEN

Child sexual abuse (CSA) is a causal agent in many negative adulthood outcomes, including the risk for life-threatening behaviors such as suicide ideation and suicide attempts. Traumatic events such as CSA may pose risk in the healthy development of cognitive and emotional functioning during childhood. In fact, high impulsivity, a risk factor for suicidal behavior, is characteristic of CSA victims. The current study aims to understand the relations among CSA, impulsivity, and frequency of lifetime suicide attempts among a female patient sample admitted for suicidal behavior. Participants included 177 female patients between the ages of 18 and 63 years admitted at two hospitals in Buenos Aires, Argentina. Number of previous suicide attempts and CSA were assessed via structured interviews, while impulsivity was assessed with the Barratt Impulsiveness Scale (BIS-11). A model of structural equations was employed to evaluate the role of impulsivity in the relation between CSA and suicide attempts. CSA (ß=.18, p<.05) and impulsivity (ß=.24, p<.05) were associated with the number of previous suicide attempts. However, impulsivity was not significantly associated with CSA (ß=.09, p>.05). CSA and impulsivity are independently associated with lifetime suicide attempts among female patients with recent suicidal behavior.
