RESUMEN

The current study examines the effects of trait aggressiveness, inhibitory control and emotional states on aggressive behavior in a laboratory paradigm. One hundred and fifty-one adult participants took part (73 men, 71 women, and 7 nondisclosed). Event Related Potentials (ERPs) during a Go/No-Go task were utilized to capture the extent of inhibitory processing, with a laboratory provocation paradigm used to assess aggression. Contrary to the expectations, negative affective responses to provocation were negatively associated only with short-lived aggression and only among those with high past aggressiveness. Furthermore, past aggressiveness was related to a continuous increase in laboratory aggressive behavior regardless of the level of inhibitory control (P3 difference amplitude). However, feeling hostile was associated with short-lived aggressive behavior, only in those with lower levels of inhibitory control. These findings demonstrate the effect of distinct mechanisms on different patterns of aggressive behavior.

RESUMEN

Although aggression occurs across a range of disorders, associations between dimensions of psychopathology and self- and other-directed aggression are not well understood. Investigating associations between psychopathology dimensions and aggression helps further understanding about the etiology of aggression, and ultimately, can inform intervention and prevention strategies. This study adopted a multi-method approach to examine associations between internalizing and externalizing dimensions of psychopathology and self- and other-directed aggression as a function of reporter (participant and informant) and modality of aggression measurement (subjective and objective). Participants were an unselected sample of 151 racially diverse adults recruited from the community. Dimensions of psychopathology were assessed using interview and questionnaire reports from participants and collateral informants, and forms of aggression were measured via subjective reports and an objective, laboratory aggression paradigm. Analyses of participant-reported psychological symptom data consistently linked externalizing symptoms to other-directed aggression, and internalizing symptoms to self-directed aggression. Results across informant and participant reporters replicated prior findings showing a significant interaction between internalizing and externalizing dimensions in predicting intimate partner violence. Most other effects in informant models were nonsignificant. The findings uncover consistency in and replicability of relationships between dimensions of psychopathology and certain manifestations of aggression and highlight the importance of examining multiple forms of aggression in etiological research. Examining aggression through a transdiagnostic lens can help us better understand and intervene upon processes implicated in devasting forms of self- and other-directed aggression.

RESUMEN

OBJECTIVES: Rates of suicide exposure are high among service members and Veterans and are especially concerning given the link between suicide exposure and subsequent suicide risk. However, to date, it is unclear which individuals who are exposed to suicide are subsequently at high risk for suicide. Latent profile analysis (LPA) can provide information on unique risk profiles and subgroups of service members and Veterans who have higher suicide risk after suicide exposure, which has not yet been empirically studied. The purpose of this study was to utilize LPA to identify subgroups of service members and Veterans who are at the highest risk for suicidal thoughts and behaviors following suicide exposure. METHODS: We analyzed data using LPA from 2570 service members and Veterans (82.1% male, 69.5% White, and 12.1% Latino/a/x) who completed the Military Suicide Research Consortium's Common Data Elements, a battery of self-report suicide-related measures. Psychopathology, substance use, mental health service utilization, interpersonal theory of suicide, and suicide exposure variables were used to validate classes. RESULTS: Three latent classes emerged from analyses, one low-risk class and two-high risk classes with differing profile compositions (one primarily differentiated by anxiety symptoms and one differentiated by substance use). CONCLUSION: Class-specific recommendations for suicide prevention efforts will be discussed.

RESUMEN

OBJECTIVE: To examine prevalence of Alzheimer Disease and related dementias (ADRD) and patient characteristics as a function of comorbid insomnia and/or depression among heart failure (HF) patients discharged from hospitals. DESIGN: Retrospective cohort descriptive epidemiology study. SETTING: VA Hospitals. PARTICIPANTS: N = 373,897 Veterans hospitalized with heart failure from October 1, 2011 until September 30, 2020. MEASUREMENTS: We examined VA and Center for Medicare & Medicaid Services (CMS) coding in the year prior to admission using published ICD-9/10 codes for dementia, insomnia, and depression. The primary outcome was the prevalence of ADRD and the secondary outcomes were 30-day and 365-day mortality. RESULTS: The cohort were predominantly older adults (mean age = 72 years, SD = 11), male (97%), and White (73%). Dementia prevalence in participants without insomnia or depression was 12%. In those with both insomnia and depression, dementia prevalence was 34%. For insomnia alone and depression alone, dementia prevalence was 21% and 24%, respectively. Mortality followed a similar pattern with highest 30-day and 365-day mortality higher in those with both insomnia and depression. CONCLUSIONS: These results suggest that persons with both insomnia and depression are at an increased risk of ADRD and mortality compared to persons with one or neither condition. Screening for both insomnia and depression, especially in patients with other ADRD risk factors, could lead to earlier identification of ADRD. Understanding comorbid conditions which may represent earlier signs of ADRD may be critical in the identification of ADRD risk.

RESUMEN

Veteran and service member suicide remains a significant public health concern. One factor that may impact suicide risk is suicide exposure-knowing someone who has died by suicide or attempted suicide. However, the majority of the extant literature has focused on nonmilitary samples, which may not generalize to military veterans and service members. The current review synthesizes findings regarding suicide exposure in military veterans, service members, their families, and military systems. Our review suggests that the relationship between suicide exposure, suicide risk, and mental health outcomes remains inconsistent. Future research should further explore this important area.

RESUMEN

Rates of Veteran suicide continue to be unacceptably high. Suicidal ideation and behavior are contextually and situationally based, limiting the ability of traditional prevention and assessment strategies to prevent acute crises. The Mobile Application for the Prevention of Suicide (MAPS) is a novel, smartphone-based intervention strategy that utilizes ecological momentary assessment to identify suicide risk in the moment and delivers treatment strategies in real-time. The app is personalized to each patient, utilizes empirically intervention strategies, and is delivered adjunctively to Veterans Affairs (VA) treatment as usual. This article outlines the MAPS intervention and presents results of an open trial to assess its feasibility and acceptability. Eight Veterans were recruited from aVeterans Affairs Medical Center (VAMC) psychiatric inpatient unit following hospitalization for either a suicide ideation or attempt. Veterans received MAPS for 2 weeks post-hospitalization. Veterans reported high levels of satisfaction with MAPS and all opted to extend their use of MAPS beyond the 2-week trial period. MAPS may be a useful adjunctive to treatment as usual for high-risk Veterans by allowing patients and their providers to better track suicide risk and deploy intervention strategies when risk is detected.

RESUMEN

Literature linking aggressive behavior across internalizing and externalizing disorders support the co-occurrence of aggression and various mental health diagnoses. However, research has yet to examine relationships between aggression and dimensional psychopathology models that cut across diagnostic boundaries (e.g., internalizing, externalizing composites) and capture shared liability across common disorders. The role of gender has also been largely ignored in prior work, despite evidence that men and women manifest psychopathology differently. The present study examined cross-sectional and longitudinal relationships between psychopathology composites (i.e., Internalizing, Externalizing) and different manifestations of physical aggression (i.e., aggressive traits, general violence, physical intimate partner violence, and self-directed aggression), as well as moderation by gender. Internalizing (INT) and Externalizing (EXT) lifetime symptoms and various physically aggressive behaviors were assessed at baseline and at 6 months and 1 year follow up in a sample of 319 adults with violence and/or substance use histories. Cross-sectional results showed that INT was associated with all forms of aggression, and women showed stronger relationships between INT and both physical intimate partner violence (IPV) and self-directed aggression. EXT was specifically linked to general violence, and a stronger relationship between EXT and self-directed aggression emerged in men compared to women. Longitudinal relationships were mostly small and nonsignificant. Results support the co-occurrence of aggression with distinct forms of psychopathology, as well as gender-dependent relationships, but do not support the predictive validity of symptom composites in aggression risk. Findings implicate the need for aggression interventions tailored within gender.

RESUMEN

Background: Mental health professionals (MHPs) often lack skills necessary to effectively manage suicide risk. Training designed to combat this deficiency tend to rely on passive techniques, despite research suggesting active methods may better facilitate skill development.Aim: This study examines the effect of a role-play training on MHPs' attitudes, subjective norms and perceived behavioral control surrounding suicide risk assessment behaviors.Methods: Two hundred and three MHPs participated in a 4.5 hour role-play training after participation in an online suicide risk assessment training. The training utilized active learning and behavioral modification strategies. MHPs completed questionnaires assessing attitudes, subjective norms, perceived behavioral control and training variables.Results: MHPs endorsed positive attitudes, social norms and perceived behavioral control in suicide risk assessment and management skills, especially in assessing/determining the severity of risk, establishing rapport, documenting risk assessment information and developing a treatment plan. Results also revealed support for the feasibility of disseminating role-play training utilizing active learning methods.Conclusion: Factors found to be associated with participation in the role-play training are discussed. Findings may inform future development and improvement of suicide risk assessment training and practices that target risk and protective factors to effectively reduce suicide-related behavior.

RESUMEN

The present study examined differences in symptom presentation in screening for pediatric depression via evaluation of the Patient Health Questionnaire-9 (PHQ-9). In particular, we examined whether PHQ-9 items function differentially among deaf and hard-of-hearing (DHH; n = 75) and hearing (n = 75) youth based on participants recruited from crisis assessment services. Multiple indicators multiple causes models were used to examine whether items of the PHQ-9 functioned differently between groups as well as whether there were group differences in the mean severity of depressive symptoms. Results indicate that DHH youth were more likely to endorse psychosomatic items, and less likely to endorse an affective item. These findings indicate that the PHQ-9 functions differently when used with DHH youth. Implications of these findings are discussed, including both for future work with the PHQ-9 and with regard to the conceptualization of depression across hearing groups.

RESUMEN

OBJECTIVE: Males are more likely than females to die by all forms of violent death, including suicide. The primary purpose of the present study was to explore whether the gender difference in suicide rates is largely accounted for by males' general greater tendency to experience violent deaths. The current study examined gender and age differences in suicides and other violent deaths, using data from a population-based surveillance system. METHOD: Pearson's chi-square tests and logistic regression analyses were conducted with data for 32,107 decedents in the 2003-2005 National Violent Death Reporting System (NVDRS). Decedents were categorized by gender, age, and death by suicide versus other violent means. RESULTS: When suicides were examined in the greater context of violent death, the total proportion of violent deaths due to suicide did not differ across gender. When deaths were examined by age group, after controlling for ethnicity, marital status, and U.S. location in which the death occurred, males in early to mid childhood were significantly more likely than same-aged females to die by suicide relative to all other violent deaths. The portion of deaths due to suicide was for the most part equal across both genders in late childhood, young adulthood, and mid-adulthood. Older males were more likely than older females to die by suicide relative to other violent deaths. CONCLUSION: Our findings suggest that that the risk of dying by suicide relative to other violent deaths may be more pronounced at certain developmental stages for each gender. This knowledge may be valuable in tailoring prevention strategies.

RESUMEN

Objective: Shorter sleep duration has been linked to increased suicidal ideation (SI). However, limited research has examined the relationship between nightly sleep duration and short-term fluctuations in suicide risk, as well as the potential clinical utility of leveraging indices of recent (ie, past 3 days) patterns of sleep duration as a marker of acute suicide risk. This study examined associations between nightly and cumulative sleep duration and suicidal desire and intent utilizing ecological momentary assessment (EMA) in a high risk sample of community-based adults.Methods: A sample of 237 community based adults with severe SI provided daily indices of self-reported sleep duration and ratings of suicidal desire and intent 6 times per day for 14 consecutive days of EMA monitoring. Data collection took place between February and May 2019.Results: Between-person nightly sleep duration and cumulative sleep duration were negatively associated with suicidal desire (Bs = -3.48 and -4.78) and intent (Bs = -1.96 and -2.46). At the within person level, nightly sleep duration was negatively related to suicidal desire (Bs = -0.51 and -0.47) and intent. Within person cumulative sleep duration, on the other hand, was unrelated to both suicidal desire and intent (Bs = -0.26 and -0.09).Conclusion: Our findings highlight the clinical utility of examining individual differences in sleep duration as a marker for suicide-related outcomes, as well as deviations from one's typical nightly sleep as a potential acute predictor of suicide-related outcomes, in addition to information about recent duration over one or more nights of sleep. Limitations and future directions are discussed.

RESUMEN

INTRODUCTION: Firearms account for more than half of suicide deaths in the United States (US) and both ownership and access are associated with increased risk of intentional and unintentional injury. Despite evidence linking ownership and access to suicide risk, individuals may be reticent to answer questionnaire items assessing ownership. The current study examined characteristics of individuals who do not provide a response (nonresponders) to a firearm ownership item in a community sample. METHODS: Data were collected from a cross-sectional online survey of 10,625 US adults. Univariate and multivariate analyses were conducted to examine demographic, emotional distress, and suicide risk differences across three groups (firearm owners, nonowners, and nonresponders). RESULTS: Nonresponders were significantly younger, more likely to be female and non-White than firearm owners and nonowners. Nonresponders were less likely to endorse recent suicidal ideation and probable PTSD than firearm owners, but more likely to endorse probable PTSD than nonowners. Firearm owners were significantly more likely to report several correlates of suicide risk than nonowners. CONCLUSIONS: Nonresponders may be a unique subgroup with distinct demographic, emotional distress, and suicide risk profiles compared to both firearm owners and nonowners. Implications of these findings for future directions are discussed.

RESUMEN

INTRODUCTION: Several characteristics of suicidal ideation, including frequency, duration, perceived controllability, and intensity, have been identified. The present study examined whether these characteristics of baseline suicidal ideation uniquely predicted (1) the severity, variability, and frequency of suicidal ideation assessed through real-time monitoring; and (2) suicide attempts at 3-week and 6-month follow-up among recently discharged psychiatric inpatients. METHODS: A sample of 249 adults (Mage = 40.43, 55.1% female, 91.4% White) completed a baseline assessment of their suicidal ideation characteristics during psychiatric hospitalization, five daily ecological momentary assessments (EMA) for 21 days following discharge, and follow-up assessments of suicide-related outcomes at 3-week and 6-month follow-up. RESULTS: Perceived controllability of suicidal thoughts was uniquely associated with the variability of EMA-assessed suicidal ideation and the presence of suicide attempts at 3-week, but not 6-month follow-up. No other characteristic of baseline suicidal ideation was uniquely associated with EMA-assessed suicidal ideation or the presence of suicide attempts at follow-up. CONCLUSIONS: Given links between the perceived controllability of suicidal ideation and (1) momentary variability of suicidal ideation and (2) suicide attempts over the subsequent 3 weeks, perceived controllability of suicidal thinking may be a useful marker of short-term risk that may be malleable to clinical intervention.

RESUMEN

Although suicide is complex and heterogeneous, most suicide theories assume that suicidal urges occur primarily in the context of extreme emotional distress. Newer models of suicide based on complex systems theory propose greater heterogeneity in suicidal experiences across individuals and groups, such that some, but not all, suicidal thoughts, urges, and behaviors are associated with extreme negative affect. The present study investigated individual differences in affective states experienced during suicidal urges among 138 adults recruited from the community; 81 (59.1 %) owned handguns and 57 (41.6 %) did not. Participants self-reported their current affect and urge to kill themselves 6 times per day for 28 consecutive days via ecological momentary assessment. Positive and negative affect ratings varied significantly during suicidal urges. The association of positive and negative affect with suicidal urges significantly varied within and between handgun owners and non-owners. Results suggest suicidal urges are characterized by high affective heterogeneity.

RESUMEN

OBJECTIVE: Adults with serious mental illness (SMI) have high rates of cardiovascular disease, particularly heart failure, which contribute to premature mortality. The aims were to examine 90- and 365-day all-cause medical or surgical hospital readmission in Veterans with SMI discharged from a heart failure hospitalization. The exploratory aim was to evaluate 180-day post-discharge engagement in cardiac rehabilitation, an effective intervention for heart failure. METHODS: This study used administrative data from the Veterans Health Administration (VHA) and Centers for Medicare & Medicaid Services between 2011 and 2019. SMI status and medical comorbidity were assessed in the year prior to hospitalization. Cox proportional hazards models (competing risk of death) were used to evaluate the relationship between SMI status and outcomes. Models were adjusted for VHA hospital site, demographics, and medical characteristics. RESULTS: The sample comprised 189,767 Veterans of which 23,671 (12.5%) had SMI. Compared to those without SMI, Veterans with SMI had significantly higher readmission rates at 90 (16.1% vs. 13.9%) and 365 (42.6% vs. 37.1%) days. After adjustment, risk of readmission remained significant (90 days: HR: 1.07, 95% CI: 1.03, 1.11; 365 days: HR: 1.10, 95% CI: 1.07, 1.12). SMI status was not significantly associated with 180-day cardiac rehabilitation engagement (HR: 0.98, 95% CI: 0.91, 1.07). CONCLUSIONS: Veterans with SMI and heart failure have higher 90- and 365-day hospital readmission rates even after adjustment. There were no differences in cardiac rehabilitation engagement based on SMI status. Future work should consider a broader range of post-discharge interventions to understand contributors to readmission.

RESUMEN

Medical comorbidity, particularly cardiovascular diseases, contributes to high rates of hospital admission and early mortality in people with schizophrenia. The 30 days following hospital discharge represents a critical period for mitigating adverse outcomes. This study examined the odds of successful community discharge among Veterans with schizophrenia compared to those with major affective disorders and those without serious mental illness (SMI) after a heart failure hospital admission. Data for Veterans hospitalized for heart failure were obtained from the Veterans Health Administration (VHA) and Centers for Medicare & Medicaid Services between 2011 and 2019. Psychiatric diagnoses and medical comorbidities were assessed in the year prior to hospitalization. Successful community discharge was defined as remaining in the community without hospital readmission, death, or hospice for 30 days after hospital discharge. Logistic regression analyses adjusting for relevant factors were used to examine whether individuals with a schizophrenia diagnosis showed lower odds of successful community discharge versus both comparison groups. Out of 309,750 total Veterans in the sample, 7377 (2.4%) had schizophrenia or schizoaffective disorder and 32,472 (10.5%) had major affective disorders (bipolar disorder or recurrent major depressive disorder). Results from adjusted logistic regression analyses demonstrated significantly lower odds of successful community discharge for Veterans with schizophrenia compared to the non-SMI (Odds Ratio [OR]: 0.63; 95% Confidence Interval [CI]: 0.60, 0.66) and major affective disorders (OR: 0.65, 95%; CI: 0.62, 0.69) groups. Intervention efforts should target the transition from hospital to home in the subgroup of Veterans with schizophrenia.

RESUMEN

Background: Older adults with heart failure are at elevated risk of Alzheimer's disease and related dementias (AD/ADRD). Research suggests that insomnia and depressive episodes contribute somewhat dissociable impacts on risk for AD/ADRD in this patient population, although the temporal ordering of effects is unknown. Objective: This study examined time to dementia diagnosis among patients with comorbid insomnia and/or depressive episodes in an epidemiological sample. Methods: Secondary data analyses were conducted using a cohort study of 203,819 Veterans with a primary admission diagnosis of heart failure in 129 VA Medical Centers. Results: Patients with diagnoses of both insomnia and depressive episodes had the shortest time to a dementia diagnosis at both 1-year (Hazard ratio = 1.43, 95% CI [1.36, 1.51]) and 3-year follow-up time points (Hazard ratio = 1.40, 95% CI [1.34, 1.47]) versus patients with one or neither comorbidity. Conclusions: Individuals with both comorbidities had the shortest time to dementia onset. Screening for these comorbidities may help to identify patients at elevated risk of dementia who could benefit from enhanced monitoring or early intervention strategies for more rapid detection and management of dementia symptoms.

RESUMEN

Although sleep loss is theorized to increase aggression risk, knowledge regarding the sleep-aggression relationship, or explanatory psychological processes, is limited. This study examined whether recent sleep duration predicted subsequent laboratory aggression, and whether neurocognitive indices of attentional and motor inhibition and negative emotional processing explained the sleep-aggression relationship. Participants (n=141) wore Fitbit Flex devices and kept a sleep diary for three days. Event-related potentials were measured during an Emotional-Linguistic Go/No-Go task, followed by a laboratory aggression paradigm. Results of mixed-model repeated measures ANOVAs linked shorter sleep duration with reduced motor inhibition processing during negative and neutral word blocks, and greater aggression. However, neurocognitive indices did not explain the sleep-aggression link. This is the first evidence that naturally occurring sleep loss predicts increases in laboratory aggression across the task and suggests that shorter sleepers are more vulnerable to rash action in negative and neutral contexts. Implications of these findings for understanding aggression will be discussed.

RESUMEN

The biobehavioral study of aggression has implications for expanding our understanding of transdiagnostic processes that increase risk for disinhibited behaviors. Toward this end, our study tested tenets from the process model of aggression (Verona & Bresin, 2015). First, we expected that the predictability of threat would differentially alter cognitive networks, including attentional alerting and executive control. Second, we examined the moderating effects of self- and informant reports of aggression on threat-related changes in cognitive functioning. Using event-related potential (ERP) measures of cognitive-attentional processes, 143 community individuals participated in a well-validated and translational threat manipulation (NPU) task (Schmitz & Grillon, 2012) while completing the Attention Network Test (Fan et al., 2002). Analyses revealed that relatively unpredictable threat quickened alerting-related reaction time, whereas predictable threat interfered with processing of flanker task stimuli. The results, however, failed to show reliable relationships between aggression proneness and threat-related cognitive alterations. The findings fit with a broader literature on cognitive and behavioral outputs of threat activation and provide fruitful avenues for better understanding threat-related aggression.

RESUMEN

Research identifying the biobehavioral processes that link threat exposure to cognitive alterations can inform treatments designed to reduce perpetration of stress-induced aggression. The present study attempted to specify the effects of relatively predictable versus unpredictable threat on two attention networks, attentional alerting and executive control. In a sample of adults (n = 74, 35 % identifying as women, Mage = 32.85) with high rates of externalizing behaviors (e.g., substance use, criminal/legal system involvement, aggressivity), we measured event-related brain activity during an attention network test that manipulated cognitive systems activation under relatively unpredictable and predictable threat conditions. Results showed that threat exposure alters attentional alerting and executive control. The predictable threat condition, relative to unpredictable threat, increased visual alerting (N1 amplitude to alert vs. no alert cue conditions) and decreased attention to the task (P3 amplitude to subsequent task-relevant flankers, but these effects did not survive adjusting for multiple tests. In contrast, overall threat and unpredictable threat conditions were associated with faster response time to alert cue (versus no cue) and poorer conflict processing, operationalized as flanker N2 reductions and slower response time to incongruent (versus congruent) flanker trials. These results expand what is known about threat-related modulation of cognition in a sample of individuals with histories of externalizing behaviors.
