Crisis response planning rapidly reduces suicidal ideation among U.S. military veterans receiving massed cognitive processing therapy for PTSD.

Posttraumatic stress disorder (PTSD) is common among U.S. military veterans and is associated with increased risk of suicidal thoughts and behaviors. Crisis response planning (CRP), a brief safety planning-type intervention, has been shown to rapidly reduce suicidal ideation and suicide attempts in emergency and acute care settings. CRP's effectiveness when combined with trauma-focused therapies remains unknown. In this randomized pragmatic clinical trial with one-year follow-up, 157 U.S. military personnel and veterans were randomly assigned to receive CRP or self-guided safety planning (SP) prior to beginning massed cognitive processing therapy (CPT) for PTSD. Among 51 (32.5 % of sample) participants endorsing suicidal ideation at baseline, reductions in the severity of suicidal ideation were significantly larger and faster in CRP (F(11,672)= 15.8, p < .001). Among 106 participants denying suicidal ideation at baseline, 8.5 % of CRP participants versus 11.9 % of SP participants (OR=0.69, 95 % CI=0.19-2.52) reported new-onset suicidal ideation during any follow-up assessment. PTSD symptoms significantly reduced over time with no differences between groups. Results support the effectiveness of CRP for rapidly reducing suicidal ideation and managing suicide risk during outpatient treatment for PTSD.

Group brief cognitive behavioral therapy for suicide prevention compared to dialectal behavior therapy skills group for military service members: a study protocol of a randomized controlled trial.

BACKGROUND: Suicide is a pressing matter for the military. Not only does it pose a health risk, but suicide also compromises operational readiness. Despite provision of suicide prevention clinical best practices, the Department of Defense suffers several challenges (e.g., clinician shortages) limiting the agency's ability to effectively respond to service member suicide. Implementation of evidence-based suicide-specific group therapy is a possible solution to service member well-being needs and system challenges. Service members can also gain coping skills useful beyond managing suicidal thoughts and behaviors. METHODS: This 2-arm non-inferiority randomized controlled trial compares a group therapy format of Brief Cognitive Behavioral Therapy (i.e., G-BCBT) with Dialectical Behavior Therapy (DBT) Skills Group. Both therapies are delivered in-person at a United States Naval Medical Center. Participants (N = 136) are active-duty service members with recent suicidal thoughts or suicidal behavior. Evaluation features electronically delivered questionnaires at baseline, after each treatment session, and at 3- and 6-month follow-up. DISCUSSION: The primary outcome concerns G-BCBT impacts on suicidal ideation. Secondary outcomes of interest are suicide attempt, psychological distress (e.g., symptoms of depression, anxiety), and self-regulatory skills (e.g., emotion regulation). We also examine self-regulatory skills as treatment moderators. Clinical trial strengths and limitations are reviewed. TRIAL REGISTRATION: This study was registered at Clinicaltrials.gov (protocol NCT05401838).

Differences in Guilt, Shame, Self-Anger, and Suicide Cognitions Based on Recent Suicide Ideation and Lifetime Suicide Attempt History.

ABSTRACT: Suicide risk factors such as hopelessness and psychiatric disorders can predict suicide ideation (SI) but cannot distinguish between those with SI and those who attempt suicide (SA). The fluid vulnerability theory of suicide posits that a person's activation of the suicidal mode is predicated on one's predisposition, triggers, and baseline/acute risks. This study compared guilt, shame, self-anger, and suicidal beliefs based on recent SI and lifetime SA. In a total of 2222 primary care patients in this cross-sectional, observational study reported no recent SI or lifetime SA (SI-SA-), 161 reported recent SI only (SI-SA+), 145 reported lifetime SA only (SI+SA-), and 56 reported both recent SI and lifetime SA (SI+SA+). Kruskal-Wallis test showed that the four risk factors were the highest for SI+SA+, followed by SI+SA-, then SI-SA+, and lastly SI-SA-. The study shows that risk factors may be worse in those with recent SI than those with SA history.

An empirical investigation of the distinction between passive and active ideation: Understanding the latent structure of suicidal thought content.

INTRODUCTION: Although the distinction between passive and active suicidal ideation is well accepted by suicide researchers and clinicians, there has been very little empirical investigation into this distinction. The current study addressed this gap by examining the latent structure of suicidal ideation based on thought content. METHOD: Participants from two distinct samples of U.S. adults (n1 = 6200; n2 = 10,625) completed a self-report assessment of eight commonly experienced suicidal thoughts using the Self-Injurious Thoughts and Behaviors Interview-Revised. Exploratory structural equation modeling was used to examine the latent structure of suicidal thoughts. RESULTS: The two-factor model demonstrated significantly better fit than the one-factor solution across both samples. Thoughts typically classified as passive ideation strongly loaded onto one factor, whereas thoughts typically classified as active ideation loaded onto the second factor. The two factors were highly correlated and some suicidal thoughts exhibited meaningful cross-loading. CONCLUSION: Our results suggest that passive and active ideation are two distinct constructs. Although they often co-occur, passive and active ideation are not nested constructs and should not be viewed as gradients of one underlying construct. Our findings suggest that at a minimum both passive and active ideation should be included in all suicide risk assessments and screenings.

Assessment of Latent Subgroups With Suicidal Ideation and Suicidal Behavior Among Gun Owners and Non-Gun Owners in the US.

Importance: Firearm ownership is associated with increased risk for suicide. Objective: To examine patterns of associations among suicidal thoughts and behaviors among gun owners and non-gun owners in the US. Design, Setting, and Participants: In this survey study, cross-sectional online survey data were collected from March to April 2020 from US adults recruited via Qualtrics Panels. Quota sampling was used to approximate US census demographics. Main Outcomes and Measures: The primary outcomes were past-year passive suicidal ideation, active suicidal ideation, suicidal planning, suicidal behaviors, and nonsuicidal self-injury as measured by items from the Self-Injurious Thoughts and Behaviors Interview-Revised (SITBI-R). Simple latent class analysis (LCA) was used to assign participants to separate classes based on posterior probabilities, and multigroup LCA was used to assess whether the same construct was measured in specified groups. Results: Of 65 079 adults invited to participate, 10 625 (16.3%) completed the survey; 9153 responded "yes" or "no" to the firearm ownership item and were included in the analysis. Of these 9153 respondents (4695 [51.3%] male; mean [SD] age, 46.7 [16.8] years), 2773 (30.3%) reported owning a gun and 6380 (69.7%) reported not owning a gun. Compared with non-gun owners, gun owners were more likely to be male (1779 [64.2%] vs 2916 [45.7%]; χ21, 263.3; P < .001) and White (2090 [75.4%] vs 3945 [61.8%]; χ25, 232.9; P < .001) and to have served in the military (772 [27.8%] vs 609 [9.5%]; χ21, 571.4; P < .001). Five distinct patterns of SITBI-R item endorsement were extracted using simple LCA. Multigroup LCA indicated that the probability of SITBI-R item endorsement differed between gun owners and non-gun owners across subgroups. Among gun owners, the probability of past-month nonfatal suicide attempts was highest in class 4 (ranging from 16.8% for reaching out for help to 27.2% for starting, then changing one's mind). Gun owners in class 4 were characterized by high probabilities of endorsing thoughts about specific ways or methods to attempt suicide (100%) and preparatory behavior (100%). Among non-gun owners, the probability of nonfatal suicide attempts was highest in class 5 (ranging from 14.9% for reaching out for help to 29.7% for starting, then changing one's mind). Non-gun owners in class 5 were characterized by high probabilities of endorsing passive suicidal ideation (84.0%-100%), active suicidal ideation (86.7%-95.0%), and thoughts about specific ways or methods to attempt suicide (97.4%) and a specific place (92.1%) to attempt suicide. Conclusions and Relevance: In this study, in subgroups with lower probabilities of suicide attempt, gun owners and non-gun owners showed similar patterns of suicide risk item endorsement, but when the probability of a suicide attempt increased, gun owners were less likely than non-gun owners to endorse passive and active suicidal ideation. These findings suggest that assessing a broader range of suicide risk indicators may improve risk detection.
