RESUMO
OBJECTIVE: Examine the association between insomnia symptom severity and suicidal ideation (SI), after adjusting for clinical comorbidity in veterans meeting diagnostic criteria for insomnia disorder. METHODS: Secondary data analyses of psychometrically validated baseline assessments of depression, posttraumatic stress disorder (PTSD), and anxiety symptoms from two online insomnia intervention randomized clinical trials (n = 232; n = 80) were conducted. Multiple linear regression was used to determine the association between insomnia symptom severity and SI, after controlling for clinical comorbidity and demographics. RESULTS: Insomnia symptom severity was significantly correlated with comorbid depression, PTSD, and anxiety symptoms in both cohorts and significantly correlated with SI in one. After controlling for demographics and clinical comorbidity, insomnia symptom severity was not significantly associated with SI in linear regression models. CONCLUSION: Findings extend insomnia-suicide research by providing evidence that insomnia symptom severity may not confer a unique risk for SI above comorbid mental health symptoms in veterans meeting diagnostic criteria for insomnia disorder.

OBJECTIVE: The current study aimed to (a) assess basic nonsuicidal self-injury (NSSI) characteristics using a validated clinical interview among a sample of veterans not recruited for specific diagnostic or environmental criteria and (b) examine the relation between NSSI and medical severity of prior suicide attempts (SAs) among veterans. DESIGN: We conducted secondary data analyses among a combined sample of veterans (N = 165) from two parent studies conducted at a large VA Medical Center that implemented identical recruitment protocols. No psychiatric criteria were utilized for inclusion or exclusion purposes. RESULTS: Approximately 16% of participants reported NSSI history and almost 21% reported SA history. NSSI history was associated with probability of prior SA but not the medical severity of prior SA. CONCLUSIONS: NSSI is a prevalent concern among veterans and is associated with probability of SA. It remains unclear whether prior NSSI is associated with more medically serious SA in this population.

Toxoplasma gondii (T. gondii) infects central nervous tissue and is kept in relative dormancy by a healthy immune system. Sleep disturbances have been found to precipitate mental illness, suicidal behavior and car accidents, which have been previously linked to T. gondii as well. We speculated that if sleep disruption, particularly insomnia, would mediate, at least partly, the link between T. gondii infection and related behavioral dysregulation, then we would be able to identify significant associations between sleep disruption and T. gondii. The mechanisms for such an association may involve dopamine (DA) production by T. gondii, or collateral effects of immune activation necessary to keep T. gondii in check. Sleep questionnaires from 2031 Old Order Amish were analyzed in relationship to T. gondii-IgG antibodies measured by enzyme-linked immunosorbent assay (ELISA). Toxoplasma gondii seropositivity and serointensity were not associated with any of the sleep latency variables or Epworth Sleepiness Scale (ESS). A secondary analysis identified, after adjustment for age group, a statistical trend toward shorter sleep duration in seropositive men (p = 0.07). In conclusion, it is unlikely that sleep disruption mediates links between T. gondii and mental illness or behavioral dysregulation. Trending gender differences in associations between T. gondii and shorter sleep need further investigation.
RESUMO
OBJECTIVE: To examine the discrepancy between sleep diary and actigraphic measures of sleep in Veterans with moderate-severe post-acute traumatic brain injury (TBI) and to explore whether these discrepancies vary according to participant characteristics. SETTING: VA Medical Center in the Rocky Mountain United States. PARTICIPANTS: Nineteen males with moderate-severe post-acute TBI and insomnia symptoms as measured by the Insomnia Severity Index. DESIGN: Descriptive, cross-sectional. MAIN MEASURES: Sleep diary, wrist actigraphy, Ohio State University TBI-Identification Method, Insomnia Severity Index, and Hospital Anxiety and Depression Scale. RESULTS: There was poor agreement between actigraphic and sleep diary measurements of (1) total sleep time, (2) wake after sleep onset, and (3) sleep onset latency. On average, actigraphy measured greater duration of all 3 sleep parameters. Discrepancies were not found to be associated with specific TBI characteristics or mood-related symptoms. CONCLUSION: When measuring sleep-related outcomes among Veterans with moderate-severe post-acute TBI, notable mismatches were found between actigraphic and self-reported sleep diary data. Knowledge regarding measure-related limitations is important for both clinical and research practices among those with moderate-severe post-acute TBI.

BACKGROUND: Although rates of anxiety tend to decrease across late life, rates of anxiety increase among a subset of older adults, those with mild cognitive impairment (MCI) or dementia. Our understanding of anxiety in dementia is limited, in part, by a lack of anxiety measures designed for use with this population. This study sought to address limitations of the literature by developing a new measure of anxiety for cognitively impaired individuals, the anxiety in cognitive impairment and dementia (ACID) Scales, which includes both proxy (ACID-PR) and self-report (ACID-SR) versions. METHODS: The ACID-SR and ACID-PR were administered to 45 residents, aged 60 years and older, of three long-term care (LTC) facilities, and 38 professional caregivers at these facilities. Other measures of anxiety, and measures of depression, functional ability, cognition, and general physical and mental health were also administered. RESULTS: Initial evaluation of its psychometric properties revealed adequate to good internal consistency for the ACID-PR and ACID-SR. Evidence for convergent validity of measures obtained with the ACID-SR and ACID-PR was demonstrated by moderate-to-strong associations with measures of worry, depressive symptoms, and general mental health. Discriminant validity of measures obtained with the ACID-SR and ACID-PR was demonstrated by weak correlations with measures of cognition, functional ability, and general physical well-being. CONCLUSIONS: The preliminary results suggest that the ACID-SR and ACID-PR can obtain reliable and valid measures of anxiety among individuals with cognitive impairment. Given the subjective nature of anxiety, it may be prudent to collect self-report of anxiety symptoms even among those with moderate cognitive impairment.

Improving public health approaches to suicide prevention requires scalable evidence-based interventions that can be easily disseminated. Given empirical data supporting the association between insomnia and suicide risk, internet-delivered insomnia interventions are promising candidates to meet this need. The purpose of this study was to examine whether an unguided internet-delivered cognitive-behavioral therapy for insomnia (iCBT-I) improved insomnia severity, suicidal ideation (SI), and suicide risk correlates (depression, post-traumatic stress disorder, anxiety, hostility, belongingness, hopelessness, agitation, irritability, concentration) in a sample of veterans. Secondary data analysis of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn veterans (n = 50) with clinically significant insomnia and elevated SI drawn from a larger randomized controlled trial (RCT) of an iCBT-I, Sleep Healthy Using the Internet (SHUTi). Two-sample t-tests or Wilcoxon rank sum tests were used to evaluate between-group differences (SHUTi vs. Insomnia Education Website control) in symptom improvement from baseline to post-intervention. SHUTi participants experienced a significant improvement in insomnia severity (P < .001; d = -1.08) and a non-significant with small (subthreshold medium) effect size reduction of SI (P = .17, d = 0.40), compared to control participants. Significant improvement in hopelessness was observed (medium effect size), with non-significant small to medium effect size reductions in most remaining suicide risk correlates. Self-administered iCBT-I was associated with improvements in insomnia severity in veterans at elevated risk for suicide. These preliminary findings suggest that SI and suicide risk correlates may improve following an iCBT-I intervention, demonstrating the need for future well-powered iCBT-I RCTs targeted for populations at elevated suicide risk.
In this secondary data analysis, we examined improvements in insomnia severity, suicidal ideation (SI), and suicide risk correlates in veterans with clinically significant insomnia and elevated SI drawn from a larger randomized controlled trial (RCT) examining an unguided internet-delivered cognitive-behavioral therapy for insomnia (iCBT-I). Veterans in the iCBT-I group experienced greater improvements in insomnia severity and hopelessness than veterans in the Insomnia Education Website control. Although between-group differences in SI and other suicide risk correlates were not statistically significant, effect sizes suggest that SI and symptoms of depression, irritability, concentration, post-traumatic stress disorder, and hostility may improve following iCBT-I intervention. These results suggest that digital and iCBT-I interventions may be especially powerful tools for use in suicide prevention among veterans but highlight the critical need for additional large-scale studies to examine suicide-specific mechanisms and outcomes to guide implementation efforts.
RESUMO
BACKGROUND: Despite a growing evidence base that internet-delivered cognitive behavioral therapy for insomnia (iCBT-I) is associated with decreased insomnia severity, its efficacy has been minimally examined in veterans. OBJECTIVE: The objective of this study was to evaluate the efficacy of an unguided iCBT-I (Sleep Healthy Using the Internet [SHUTi]) among veterans. METHODS: We conducted a single-blind, randomized controlled trial in Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn veterans eligible for Veterans Health Administration care. Participants were randomly assigned (1:1) to receive SHUTi (a self-guided and interactive program) or an Insomnia Education Website (IEW) that provided nontailored and fixed insomnia information. Web-based assessments were administered at baseline, postintervention, 6 months postintervention, and 1 year postintervention. The primary outcome was self-reported insomnia severity (Insomnia Severity Index [ISI]). Secondary outcomes were self-reported mental and physical health functioning (Veterans RAND 36-item Health Survey). Exploratory outcomes comprised sleep diary parameters. RESULTS: Of the 231 randomized participants (mean age 39.3, SD 7.8 years; 170/231, 73.5% male sex; 26/231, 11.3% Black; 172/231, 74.5% White; 10/231, 4.3% multiracial; and 17/231, 7.4% other; 36/231, 15.6% Hispanic) randomized between April 2018 and January 2019, a total of 116 (50.2%) were randomly assigned to SHUTi and 115 (49.8%) to the IEW. In intent-to-treat analyses, SHUTi participants experienced significantly larger ISI decreases compared with IEW participants at all time points (generalized η2 values of 0.13, 0.12, and 0.10, respectively; all P<.0001). These corresponded to estimated larger differences in changes of -3.47 (95% CI -4.78 to -2.16), -3.80 (95% CI -5.34 to -2.27), and -3.42 (95% CI -4.97 to 1.88) points on the ISI for the SHUTi group. SHUTi participants experienced significant improvements in physical (6-month generalized η2=0.04; P=.004) and mental health functioning (6-month and 1-year generalized η2=0.04; P=.009 and P=.005, respectively). Significant sleep parameter improvements were noted for SHUTi (all P<.05), though the pattern and magnitude of these reductions varied by parameter. No adverse events were reported. CONCLUSIONS: Self-administered iCBT-I was associated with immediate and long-term improvements in insomnia severity. Findings suggest that leveraging technology to meet insomnia treatment demands among veterans may be a promising approach.

RESUMO
Although sleep disruption has emerged as a theoretically consistent and empirically supported suicide risk factor, the mechanistic pathways underlying the sleep-suicide link are less understood. This paper describes the methodology of a study intended to examine longitudinal mechanisms driving the link between sleep and suicide in Veterans at elevated suicide risk. Participants will be 140 Veterans hospitalized for suicide attempt or ideation with plan and intent or those identified through the Suicide Prevention Coordinator (SPC) office as being at acute risk. After study enrollment, actigraphy and ecological momentary assessment (EMA) data will be collected for 8 weeks, with follow-up assessments occurring at 2, 4, 6, 8, and 26 weeks. Participants respond to EMA questionnaires, derived from psychometrically validated assessments targeting emotional reactivity, emotion regulation, impulsivity, suicide risk, and sleep timing constructs, five times a day. First and last daily EMA target sleep parameters including sleep quantity, quality, timing, nightmares, and nocturnal awakenings. During follow-up assessments, participants will complete self-report assessments and interviews consistent with EMA constructs and the Iowa Gambling Task. The primary outcome for aim 1 is suicide ideation severity and for the primary outcome for aim 2 is suicide behavior. Findings from this study will improve our understanding of the dynamic interactions among sleep disturbance, emotion reactivity/regulation, and impulsivity to inform conceptual Veteran sleep-suicide mechanistic models. Improved models will be critical to optimizing the precision of suicide prevention efforts that aim to intervene and mitigate risk in Veteran populations, especially during a period of acute risk.
RESUMO
Violence risk assessment is a requisite component of mental health treatment. Adhering to standards of care and ethical and legal requirements necessitates a cogent process for conducting, and then documenting, other-directed violence (ODV) risk screening, assessment, and management. In this 5-part series, we describe a model for achieving therapeutic risk management of the potentially violent patient, with essential elements involving: clinical interview augmented by structured screening or assessment tools; risk stratification in terms of temporality and severity; chain analysis to intervene on the functions of ODV ideation and behavior; and a personalized safety plan to mitigate/manage risk. In this fourth column of the series, we describe chain analysis as a critical tool for assessing and intervening on ODV ideation and behavior. We identify the pathways of reinforcement that can cause ODV to persist, and how to navigate potential barriers to completing ODV chains. Using a case example, we demonstrate how to apply chain analysis to ODV ideation and behavior and offer interventional strategies that can be used to disrupt the chain and ultimately reduce the risk for violence.

Therapeutic management of risk for other-directed violence (ODV) involves screening, assessment, and clinically appropriate intervention. In this 5-part series, effective screening and assessment for ODV have been described as a combination of clinical interviewing and the use of structured tools to inform clinical impressions of both acute and chronic risk for violence. Once risk of violence is identified, therapeutic management of the risk throughout the course of treatment is best achieved by determining the function of the violent ideation and behavior. This can be achieved through the use of functional chain analysis. Chain analysis not only serves the purpose of providing insight into the contingencies of violent behavior but also helps to identify target areas of intervention where other skills, strategies, and means to access resources for support can be applied. In this fifth and final column of the series, we describe an intervention with all of these outcomes as its goals. A safety plan for ODV assists both clients and mental health professionals in disrupting patterns of violent ideation or behavior that would otherwise continue causing not only harm to others but prolonged negative consequences for those engaging in such behaviors.

When considering critical elements involved in suicide prevention, dialogs are often dominated by suicide assessment, management, and intervention themes. Proactive consideration on what to do if a patient dies by suicide is often overlooked, which can be especially detrimental to our practice and those we serve. In this article, we extend the philosophy of the therapeutic risk management model to consider ways in which we can take good care of the extended community of suicide loss survivors, including providers. We begin by briefly describing the widespread impact of suicide loss and the lack of suicide postvention education and awareness. Given the increased likelihood that providers will be touched by suicide loss, we then provide recommendations and resources to assist the provider in developing and/or enhancing suicide postvention practices.

BACKGROUND: Military personnel and Veterans are at increased risk for suicide. Theoretical and conceptual arguments have suggested that elevated levels of acquired capability (AC) could be an explanatory factor accounting for this increased risk. However, empirical research utilizing the Acquired Capability for Suicide Scale (ACSS) in military populations has yielded mixed findings. METHODS: To better ascertain what factors are associated with AC, and whether methodological limitations may be contributing to mixed findings, a systematic review was conducted. RESULTS: A total of 31 articles utilized the ACSS to examine factors associated with AC, including combat history, in United States (U.S.) military personnel and Veterans. Nearly all studies (96.8%) were rated high risk of bias. Use of the ACSS varied, with seven different iterations utilized. Nearly all studies examined correlations between the ACSS and sample characteristics, mental health and clinical factors, Interpersonal Theory of Suicide constructs, and/or suicide-specific variables. Results of higher-level analyses, dominated by cross-sectional designs, often contradicted correlational findings, with inconsistent findings across studies. LIMITATIONS: Included studies were non-representative of all U.S. military and Veteran populations and may only generalize to these populations. CONCLUSIONS: Due to the high risk of bias, inconsistent use of the ACSS, lack of sample heterogeneity, and variability in factors examined, interpretation of current ACSS empirical data is cautioned. Suggestions for future research, contextualized by these limitations, are discussed.

OBJECTIVES: A range of psychiatric symptoms and cognitive deficits occur in Parkinson disease (PD), and symptom overlap and comorbidity complicate the classification of nonmotor symptoms. The objective of this study was to use analytic-based approaches to classify psychiatric and cognitive symptoms in PD. DESIGN: Cross-sectional evaluation of a convenience sample of patients in specialty care. SETTING: Two outpatient movement disorders centers at the University of Pennsylvania and Philadelphia Veterans Affairs Medical Center. PARTICIPANTS: One hundred seventy-seven patients with mild-moderate idiopathic PD and without significant global cognitive impairment. MEASUREMENTS: Subjects were assessed with an extensive psychiatric, neuropsychological, and neurological battery. Latent class analysis (LCA) was used to statistically delineate group-level symptom profiles across measures of psychiatric and cognitive functioning. Predictors of class membership were also examined. RESULTS: Results from the LCA indicated that a four-class solution best fit the data. The 32.3% of the sample had good psychiatric and normal cognitive functioning, 17.5% had significant psychiatric comorbidity but normal cognition, 26.0% had few psychiatric symptoms but had poorer cognitive functioning across a range of cognitive domains, and 24.3% had both significant psychiatric comorbidity and poorer cognitive functioning. Age, disease severity, and medication use predicted class membership. CONCLUSIONS: LCA delineates four classes of patients in mild-moderate PD, three of which experience significant nonmotor impairments and comprise over two thirds of patients. Neuropsychiatric symptoms and cognitive deficits follow distinct patterns in PD, and further study is needed to determine whether these classes are generalizable, stable, predict function, quality of life, and long-term outcomes and are amenable to treatment at a class level.

STUDY OBJECTIVES: Suicide is a top public health priority, and U.S. Veterans are recognized to be at particularly elevated risk. Sleep disturbances are an independent risk factor for suicide; recent empirical data suggest that nocturnal wakefulness may be a key mechanism underlying this association. Given higher rates of sleep disturbances among U.S. Veterans compared with civilians, we examined associations between nocturnal wakefulness and timing of death by suicide in U.S. Veterans and civilians to determine whether temporal suicide patterns differed. METHODS: The American Time Use Survey and the National Violent Death Reporting System were analyzed (2006-2015) to determine whether sleep and temporal suicide patterns differed between age-stratified groups (18-39, 40-64, and ≥65) of U.S. Veterans and civilians. Observed temporal suicide patterns were reported and standardized incidence ratios (SIRs) calculated to compare the percentage of suicides observed with those expected, given the proportion of the population awake, across clock hours. RESULTS: The raw proportion of Veteran suicides peaks between the hours of 1000-1200; however, the peak prevalence of suicide after accounting for the population awake is between 0000 and 0300 hr (p < .00001, Ï = .88). The highest SIR was at midnight; U.S. Veterans were eight times more likely to die by suicide than expected given the population awake (SIR = 8.17; 95% CI = 7.45-8.94). CONCLUSIONS: Nocturnal wakefulness is associated with increased risk for suicide in U.S. Veterans. Overall patterns of observed suicides by clock hour were similar between U.S. Veterans and civilians. However, Veteran-specific SIRs suggest differences in magnitude of risk by clock hour across age groups. Future research examining female and Post-9/11 U.S. Veterans is warranted.

Suicide research remains fraught with ethical and methodological issues, including researchers' reservations about conducting intensive suicide research protocols due to potential iatrogenic effects and liability concerns. Such issues significantly impede scientific inquiry related to suicide. To date, no research has explored potential iatrogenic effects of intensive, nontreatment suicide research among Veterans. This study aimed to fill this gap. It was hypothesized that participation in suicide-specific protocols would not significantly increase risk among Veterans. Veterans completed self-reports, structured interviews, and rigorous suicide-specific tasks (Study A, N = 34; Study B, N = 18; Study C, N = 119). Findings indicated there were no significant differences in pre- and postassessment suicide risk variables (all ps > .05). Estimated mean change for "urge to harm self" was -0.24 (95% confidence interval [CI]: -0.60, 0.13), -0.28 (CI: -0.56, 0.01), and -0.01 (CI: -0.09, 0.07) and "intent to harm self" was -0.18 (95% CI: -0.45, 0.10), 0 (CI: -0.17, 0.17), and 0.01 (CI: -0.04, 0.06) for Studies A, B, and C, respectively. Results indicated the respective protocols did not produce iatrogenic effects. The current findings are discussed with attention to safety-monitoring techniques that may reduce iatrogenic effects and considerations for future researchers.

Structural approaches to suicide risk assessment (eg, evaluating the frequency and intensity of suicidal ideation and classifying types of suicidal behavior) often fall short of providing an idiographic and dynamic analysis of the factors driving and maintaining an individual's suicide risk. Structural approaches can be bolstered through chain analysis which facilitates an exploration of the factors maintaining suicidal ideation and behavior based on positive and negative reinforcement. By uncovering the factors causing suicidal ideation and behavior to persist, efficient intervention strategies can be selected to target these pathways. In this column, the authors delineate the use of chain analysis to guide suicide risk assessment and inform treatment planning.

This study evaluated whether a history of traumatic brain injury (TBI) was associated with increased risk for recent suicidal ideation (SI) after accounting for demographics, depression, posttraumatic stress disorder (PTSD), and sleep quality. In terms of increased risk, we hypothesized that a history of lifetime TBI would be associated with increased recent SI when compared with no history of TBI; multiple injuries were also evaluated. The sample included Iraq and Afghanistan war-era veterans (n = 838) who served in the United States military since 9/2001 and completed a structured TBI interview. Approximately 50% reported a lifetime history of at least 1 TBI, and 17.9% met criteria for current major depressive disorder (MDD). SI over the past week per the Beck Scale for Suicide Ideation was the primary outcome. Demographics, current MDD and posttraumatic stress disorder (PTSD) per Structured Clinical Interview of DSM-IV Axis I Disorders, sleep quality per Pittsburgh Sleep Quality Index, and TBI history per structured interview were included in all statistical models. Current depression and poor sleep quality were consistently associated with recent SI. A history of any TBI history across the life span was not associated with increased recent SI (OR = 1.35, 95% CI [0.83, 2.19]). However, a history of multiple TBIs compared with no history of TBI was associated with increased recent SI (OR = 1.76, 95% CI [1.01, 3.06]). Results support the assertion than an accumulation of injuries amplifies risk. Severity of injury and deployment injuries were not significant factors. Among those with a history of 1 TBI, sleep, and depression, which may also be injury sequelae, may be salient treatment targets. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
