RESUMEN

Decedents with no known mental disorder comprise 5-40% of suicides, suggesting that suicide ideation (SI) and behavior may occur in the psychiatrically healthy with important implications for suicide risk screening. Healthy Volunteers (HV) and patients with Major Depressive Disorder (MDD) provided 7 days of Ecological Momentary Assessment (EMA) data about SI and stressors. Longitudinal mixed effects logistic regression models compared HV and patient SI and stressors. Mixed effects linear regression models compared HVs' and patients' SI score change from the previous epoch's SI score when each stressor occurred. HVs (n = 42) reported less frequent (p < 0.001) and less intense SI (p < 0.003) than patients (n = 80), yet did endorse SI and/or SI-related items in 44% of EMA epochs, endorsing SI items in 25% of epochs with non-zero SI scores. For 7 of 8 stressors, patients reported stressors more often than HVs (all p < 0.001) responding to them with increased SI (0.0001 < p < 0.0472). HVs were relatively resilient to stressors, reporting SI increases only in response to neglect (p < 0.0147). Although SI and SAs are documented among psychiatrically healthy individuals, scientific attention to these observations has been scant. Real-time SI measurement showed that HVs' SI was less pronounced than MDD patients', but was endorsed, nonetheless. Patients were more likely to report stressors than HVs, perhaps due to greater sensitivity to the environment, and reported SI in response to stressors, which was less common in HVs. Both MDD patients and HVs most often manifested passive SI (viz, "decreased wish to live"). However, passive SI (viz, "desire for death"), may predict suicide, even absent SI per se (thinking about killing yourself). This study validates the utility of real-time SI assessment, showing that HVs endorse SI items in 11% of epochs, which implies that suicide risk screening focused on those with mental disorders may be too narrow an approach.

RESUMEN

BACKGROUND: Neurocognitive testing may advance the goal of predicting near-term suicide risk. The current study examined whether performance on a Go/No-go (GNG) task, and computational modeling to extract latent cognitive variables, could enhance prediction of suicide attempts within next 90 days, among individuals at high-risk for suicide. METHOD: 136 Veterans at high-risk for suicide previously completed a computer-based GNG task requiring rapid responding (Go) to target stimuli, while withholding responses (No-go) to infrequent foil stimuli; behavioral variables included false alarms to foils (failure to inhibit) and missed responses to targets. We conducted a secondary analysis of these data, with outcomes defined as actual suicide attempt (ASA), other suicide-related event (OtherSE) such as interrupted/aborted attempt or preparatory behavior, or neither (noSE), within 90-days after GNG testing, to examine whether GNG variables could improve ASA prediction over standard clinical variables. A computational model (linear ballistic accumulator, LBA) was also applied, to elucidate cognitive mechanisms underlying group differences. RESULTS: On GNG, increased miss rate selectively predicted ASA, while increased false alarm rate predicted OtherSE (without ASA) within the 90-day follow-up window. In LBA modeling, ASA (but not OtherSE) was associated with decreases in decisional efficiency to targets, suggesting differences in the evidence accumulation process were specifically associated with upcoming ASA. CONCLUSIONS: These findings suggest that GNG may improve prediction of near-term suicide risk, with distinct behavioral patterns in those who will attempt suicide within the next 90 days. Computational modeling suggests qualitative differences in cognition in individuals at near-term risk of suicide attempt.

RESUMEN

Clinical and empirical reports suggest that individuals use non-suicidal self-injury (NSSI) not only to ameliorate dysphoria, but to curb suicidal ideation or avoid suicidal behaviour. To date, however, no study has quantitatively assessed whether NSSI leads to short-term reductions in suicidal ideation. Using real-time monitoring over 7 days in a sample with borderline personality disorder, we found evidence that NSSI is followed by reductions in suicidal ideation in the subsequent hours. This suggests that NSSI may serve as an effective, albeit maladaptive, coping strategy for suicidal states. These findings have important implications for the management of suicide risk and self-harm.

RESUMEN

Serotonergic dysfunction is implicated in major depressive disorder (MDD), but the mechanisms of this relationship remain elusive. Serotonin 1A (5-HT1A) autoreceptors regulate brain-wide serotonin neuron firing and are positioned to assert large-scale effects on negative emotion. Here we investigated the relationship between raphe 5-HT1A binding and brain-wide network dynamics of negative emotion. 22 healthy-volunteers (HV) and 27 medication-free participants with MDD underwent positron emission tomography (PET) using [11C]CUMI-101 (CUMI) to quantify 5-HT1A binding in midbrain raphe nuclei and functional magnetic resonance imaging (fMRI) scanning during emotionally negative picture viewing. Causal connectivity across regions responsive to negative emotion was estimated in the fMRI data using a multivariate dynamical systems model. During negative picture viewing, MDD subjects demonstrated significant hippocampal inhibition of amygdala, basal-ganglia, thalamus, orbital frontal cortex, inferior frontal gyrus and dorsomedial prefrontal cortex (IFG, dmPFC). MDD-related connectivity was not associated with raphe 5-HT1A binding. However, greater hippocampal inhibition of amygdala, thalamus, IFG and dmPFC correlated with hippocampal 5-HT1A binding. Correlation between hippocampal 5-HT1A binding and the hippocampal inhibition network was specific to MDD but not HV. MDD and HV groups also differed with respect to the correlation between raphe and hippocampal 5-HT1A binding which was more pronounced in HV. These findings suggest that increased hippocampal network inhibition in MDD is linked to hippocampal serotonergic dysfunction which may in turn arise from disrupted linkage in raphe to hippocampus serotonergic circuitry.

RESUMEN

Suicidal behavior (SB) can be impulsive or methodical; violent or not; follow a stressor or no obvious precipitant. This study tested whether childhood trauma, affective lability, and aggressive and impulsive traits predicted greater SI variability. We also assessed whether affective lability, aggressive or impulsive traits explain childhood trauma's effects on SI variability and whether those with highly variable SI respond to stressful events with increases in SI. Finally, we assessed variable SI's trajectory over 2 years. Depressed participants (n = 51) had ecological momentary assessments (EMA) over 7 days at baseline, 3, 6, 12, 18, and 24 months. SI variability was assessed using the square Root of the Mean Square of Successive Deviations. Mixed Effects Models were fit as appropriate. Childhood trauma was associated with subsequent aggression. Physical abuse predicted both aggression and affective lability as well as SI variability, but not impulsivity. In two-predictor models, physical abuse's effect on SI variability was no longer significant, when controlling for the effect of higher aggression and impulsivity. Those with high SI variability exhibited greater increases in SI after stressors compared with those with less variability. We did not find that SI variability changed over time, suggesting it might be trait-like, at least over 2 years. Variable SI predisposes to marked SI increases after stressful events and may be a trait increasing risk for impulsive SB, at least over 2 years.

RESUMEN

ABSTRACT: Some patients engage in self-harm behaviors while in the emergency department. Risk factors for self-harm have been described for inpatient and outpatient/community settings, but not among emergency department patients. Authors conducted case-control, retrospective reviews of medical records and incident reports for emergency department patients in two academic medical centers. Variables were analyzed using conditional logistic regression. There were 113 individuals who engaged in self-harm while in the emergency department and 226 individuals who did not. Four variables were significant in the final model: a history of nonsuicidal self-harm (odds ratio [OR], 4.28; 95% confidence interval [CI], 1.95-9.41), opioid use in the prior 2 weeks (OR, 2.89; CI, 1.19-7.02), current manic episode (OR, 3.59; CI, 1.33-9.70), and a history of seizures (OR, 4.19; CI, 1.16-15.14). Risk of self-harm while in the emergency department may be mitigated with interventions that support adaptive coping skills, promptly address pain and withdrawal symptoms, and treat mania.

RESUMEN

Human trafficking survivors experience elevated suicide risk in comparison to the general population. Anti-trafficking service providers in the Philippines have identified capacity building in suicide prevention as a critical priority given the insufficient number of trained mental health professionals and lack of culturally adapted evidence-based interventions in the Philippines. We conducted a focused ethnography exploring the experiences of non-mental health professionals working in the anti-human trafficking sector in the Philippines in responding to suicidality among survivors of human trafficking (n = 20). Themes included: emotional burden on service providers, manifestations of stigma regarding suicide, lack of clarity regarding risk assessment, lack of mental health services and support systems, transferring responsibility to other providers, and the need for training, supervision, and organizational systems. We discuss implications for training service providers in the anti-human trafficking sector, as well as cultural adaptation of suicide prevention interventions with human trafficking survivors in the Philippines.

RESUMEN

BACKGROUND: Researchers and clinicians have typically relied on retrospective reports to monitor suicidal thoughts and behaviors. Smartphone technology has made real-time monitoring of suicidal thoughts possible via mobile ecological momentary assessment (EMA). However, little is known about how information gleaned from EMA compares with that obtained by retrospective reports. The authors sought to compare suicidal ideation (SI) assessed over 1 week using EMA with a retrospective gold-standard interviewer-administered measure covering the same period. METHODS: Fifty-one adults with major depressive disorder completed 1 week of EMA (6×/day) assessing SI. Following completion of EMA, participants completed an interviewer-administered Scale for Suicide Ideation (SSI) retrospectively assessing the same week. RESULTS: SI severity assessed through EMA was positively correlated with scores on the retrospective SSI. However, 58% of participants reporting ideation with EMA denied any past-week ideation on the SSI. Participants who endorsed SI during EMA but not on the SSI were no less likely to have a history of suicidal behavior than those who reported SI in both formats. CONCLUSION: EMA captures instances of suicidal thinking that go undetected through retrospective report and thereby may help us to identify an at-risk subgroup otherwise missed.

RESUMEN

OBJECTIVE: To determine the cost-effectiveness of 2 strategies for post-discharge suicide prevention, an Enhanced Contact intervention based on repeated in-person and telephone contacts, and an individual 2-month long problem-solving Psychotherapy program, in comparison to facilitated access to outpatient care following a suicide attempt. METHODS: We conducted a cost-effectiveness analysis based on a decision tree between January and December 2019. Comparative effectiveness estimates were obtained from an observational study conducted between 2013 and 2017 in Madrid, Spain. Electronic health care records documented resource use (including extra-hospital emergency care, mortality, inpatient admission, and disability leave). Direct cost data were derived from Madrid's official list of public health care prices. Indirect cost data were derived from Spain's National Institute of Statistics. RESULTS: Both augmentation strategies were more cost-effective than a single priority outpatient appointment considering reasonable thresholds of willingness to pay. Under the base-case scenario, Enhanced Contact and Psychotherapy incurred, respectively, €2,340 and 6,260 per averted attempt, compared to a single priority appointment. Deterministic and probabilistic sensitivity analyses showed both augmentation strategies to remain cost-effective under several scenarios. Enhanced Contact was slightly cost minimizing in comparison to Psychotherapy (base-case scenario: €-196 per averted attempt). CONCLUSIONS: Two post-discharge suicide prevention strategies based on Enhanced Contact and Psychotherapy were cost-effective in comparison to a single priority appointment. Increasing contacts between suicide attempters and mental health-care providers was slightly cost minimizing compared to psychotherapy.

RESUMEN

BACKGROUND: Abnormalities in the hypothalamic-pituitary-adrenal axis, serotonergic system, and stress response have been linked to the pathogenesis of major depressive disorder. State-dependent hyper-reactivity of the hypothalamic-pituitary-adrenal axis is seen in major depressive disorder, and higher binding to the serotonin 1A receptor is observed as a trait in both currently depressed and remitted untreated major depressive disorder. Here, we sought to examine whether a relationship exists between cortisol secretion in response to a stressor and serotonin 1A receptor binding throughout the brain, both in healthy controls and participants with major depressive disorder. METHODS: Research participants included 42 medication-free, depressed subjects and 31 healthy volunteers. Participants were exposed to either an acute, physical stressor (radial artery catheter insertion) or a psychological stressor (Trier Social Stress Test). Levels of serotonin 1A receptor binding on positron emission tomography with [11C]WAY-100635 were also obtained from all participants. The relationship between [11C]WAY-100635 binding and cortisol was examined using mixed linear effects models with group (major depressive disorder vs control), cortisol, brain region, and their interactions as fixed effects and subject as a random effect. RESULTS: We found a positive correlation between post-stress cortisol measures and serotonin 1A receptor ligand binding levels across multiple cortical and subcortical regions, independent of diagnosis and with both types of stress. The relationship between [11C]WAY-100635 binding and cortisol was homogenous across all a priori brain regions. In contrast, resting cortisol levels were negatively correlated with serotonin 1A receptor ligand binding levels independently of diagnosis, except in the RN. There was no significant difference in cortisol between major depressive disorder participants and healthy volunteers with either stressor. Similarly, there was no correlation between cortisol and depression severity in either stressor group. CONCLUSIONS: This study suggests that there may be a common underlying mechanism that links abnormalities in the serotonin system and hypothalamic-pituitary-adrenal axis hyper-reactivity to stress. Future studies need to determine how hypothalamic-pituitary-adrenal axis dysfunction affects mood to increase the risk of suicide in major depression.

RESUMEN

BACKGROUND: Numerous studies have investigated the association between hormone receptor expression and clinical outcome in ovarian carcinoma (OC); however, these have largely focussed on serous OCs, with few studies reporting specifically on endometrioid OCs (EnOC). Where analyses have been stratified by histotype, expression has been assessed using the percentage of positive tumor cells, without accounting for nuclear expression intensity. METHODS: Here we assess the expression levels of progesterone receptor (PR), estrogen receptor alpha (ER) and androgen receptor (AR) using histoscore - a nuclear scoring method incorporating both proportion of positive cells and the intensity of nuclear staining - across a cohort of 107 WT1 negative EnOCs. RESULTS: Hierarchical clustering by PR, ER and AR histoscores identified four EnOC subgroups (PR+/ER+, PR+/ER-, PR-/ER+ and PR-/ER-). EnOC patients in the PR+/ER+ and PR+/ER- groups displayed favorable outcome (multivariable HR for disease-specific survival 0.05 [0.01-0.35] and 0.05 [0.00-0.51]) compared to the PR-/ER+ group. Ten-year survival for stage II PRhigh and PRlow cases was 94.1% and 42.4%. ERhigh EnOC patients (PR+/ER+, PR-/ER+) had higher body mass index compared to ERlow cases (P = 0.015) and high grade serous OC patients (P < 0.001). CONCLUSION: These data demonstrate that endometrioid OC cases with high PR expression display markedly favorable outcome. Stage II EnOCs with high PR expression represent potential candidates for de-escalation of first-line therapy. Future work should seek to characterise the sensitivity of PR and ER positive EnOCs to endocrine therapy.

RESUMEN

OBJECTIVES: The role of endocrine therapy (ET) in high grade serous ovarian carcinoma (HGSOC) is poorly defined due to the lack of phase III data and significant heterogeneity of clinical trials performed. In this study, we sought to identify predictive factors of endocrine sensitivity in HGSOC. METHODS: HGSOC patients who received at least four weeks of ET for relapsed disease following one line of chemotherapy at the Edinburgh Cancer Centre were identified. Exclusion criteria were use of endocrine therapy as maintenance therapy or of unknown duration. Duration of therapy and best CA125 response as per modified GCIG criteria were recorded. Oestrogen receptor (ER) histoscore, treatment free interval, prior lines of chemotherapy, and type of ET were evaluated as predictive factors. RESULTS: Of 431 patients identified, 269 were eligible (77.0% letrozole, 18.6% tamoxifen, 2.2% megesterol acetate, 2.2% other). The median duration of therapy was 126 days (range 28-1427 days). 32.7% remained on ET for ≥180 days and 14.1% for ≥365 days. The CA125 response and clinical benefit rates (response or stable disease) were 8.1% and 40.1% respectively. ER histoscore >200 (P = 0.0016) and a treatment free interval of ≥180 days (P < 0.0001) were independent predictive factors upon multivariable analysis. CONCLUSIONS: ET should be considered as a viable strategy to defer subsequent chemotherapy for relapsed HGSOC. Patients with an ER histoscore >200 and a treatment free interval of ≥180 days are most likely to derive benefit.

RESUMEN

BACKGROUND: Knowledge is lacking on the long-term outcomes of treatment for adolescents with repetitive suicidal and self-harming behavior. Furthermore, the pathways through which treatment effects may operate are poorly understood. Our aims were to investigate enduring treatment effects of dialectical behavior therapy adapted for adolescents (DBT-A) compared to enhanced usual care (EUC) through a prospective 3-year follow-up and to analyze possible mediators of treatment effects. METHODS: Interview and self-report data covering the follow-up interval were collected from 92% of the adolescents who participated in the original randomized trial. TRIAL REGISTRATION NUMBER: NCT01593202 (www.ClinicalTrials.gov). RESULTS: At the 3-year follow-up DBT-A remained superior to EUC in reducing the frequency of self-harm, whereas for suicidal ideation, hopelessness and depressive and borderline symptoms and global level of functioning there were no inter-group differences, with no sign of symptom relapse in either of the participant groups. A substantial proportion (70.8%) of the effect of DBT-A on self-harm frequency over the long-term was mediated through a reduction in participants' experience of hopelessness during the trial treatment phase. Receiving more than 3 months follow-up treatment after completion of the trial treatment was associated with further enhanced outcomes in patients who had received DBT-A. CONCLUSIONS: There were on average no between-group differences at the 3-year follow-up in clinical outcomes such as suicidal ideation, hopelessness, depressive and borderline symptoms. The significantly and consistently larger long-term reduction in self-harm behavior for adolescents having received DBT-A compared with enhanced usual care, however, suggests that DBT-A may be a favorable treatment alternative for adolescents with repetitive self-harming behavior.

RESUMEN

BACKGROUND: Suicide is the second leading cause of death in young people. Childhood maltreatment, neuropsychological dysfunction and psychopathology have each been shown to increase risk for suicidal behavior. However, few studies have examined their interactions and the effects of those interactions on suicidal behavior. METHODS: Across two sites, a total of 382 offspring of depressed parents underwent neuropsychological assessments. This high-risk sample included nearly equal numbers of males and females. Average age at the time of neuropsychological assessment was 18.5 years. The most prevalent lifetime psychiatric disorders were mood (43%), anxiety (37%) and alcohol and substance use disorders (21%). Childhood maltreatment was reported by 44% of offspring. Participants underwent extensive neuropsychological testing assessing the following domains: attention, memory, executive function, working memory, language fluency, and impulse control. Logistic regression was used to examine the association of reported childhood maltreatment, neuropsychological functioning, psychopathology and their interactions with suicidal behavior. Bonferroni correction was used to adjust for multiple comparisons. RESULTS: Maltreatment was associated with increased risk of suicidal behavior with odds ratios ranging between 2.40 and 4.43. Moderation analyses found that adaptive neuropsychological functioning was not protective against childhood maltreatment's effect on suicidal risk. While lifetime history of mood disorder was strongly associated with suicidal behavior, higher scores in working memory (OR = 0.21; 95% CI = 0.09, 0.45; p < .001) and executive function (OR = 0.15; 95% CI = 0.05, 0.43; p < .001) were protective against suicidal behavior even in the presence of a lifetime history of mood disorder. CONCLUSIONS: Further research is needed to determine how neuropsychological capacity protects depressed patients against the risk of suicidal behavior.

RESUMEN

BACKGROUND: Adolescents treated for self-poisoning with medication have a high prevalence of mental health problems and constitute a high-risk population for self-harm repetition. However, little is known about whether this population is also prone to injuries of other forms. METHODS: Data were extracted from the Norwegian Patient Registry to include all incidents of treated injuries in adolescents aged 10-19 years who were treated for self-poisoning with medication during 2008-2011. This longitudinal approach allowed for the inclusion of injuries of various forms both before and after the index poisoning with medication. Gender differences and associations of injuries with recorded deliberate self-harm or psychiatric comorbidity at index poisoning were analysed. Forms of injury and psychiatric illnesses were coded according to the ICD-10 system. RESULTS: 1497 adolescents treated for self-poisoning with medication were identified from the source database, including 1144 (76.4%) girls and 353 (23.6%) boys. For these 1497 adolescents a total of 2545 injury incidents were recorded in addition to the index poisoning incidents, consisting of 778 injury incidents taking place before the index poisoning and 1767 incidents taking place subsequently. Altogether 830 subjects (55.4%) had an injury treated either before or after the index poisoning. Injuries to the hand and wrist as well as injuries to the head, neck and throat were predominant in males. Females were more likely to repeat poisoning with medication, particularly those with psychiatric disorders. CONCLUSION: Adolescents treated for poisoning with medication represent a high-risk population prone to both prior and subsequent injuries of other forms, and should be assessed for suicidal intent and psychiatric illness.

RESUMEN

BACKGROUND: Safety planning is a brief intervention that has become an accepted practice in many clinical settings to help prevent suicide. Even though it is quick compared to other approaches, it frequently requires 20 min or more to complete, which can impede adoption. A self-administered, Web-based safety planning application could potentially reduce clinician time, help promote standardization and quality, and provide enhanced ability to share the created plan. OBJECTIVE: The aim of this study was to design, build, and test the usability of a Web-based, self-administered safety planning application. METHODS: We employed a user-centered software design strategy led by a multidisciplinary team. The application was tested for usability with a target sample of suicidal patients. Detailed observations, structured usability ratings, and Think Aloud procedures were used. Suicidal ideation intensity and perceived ability to cope were assessed pre-post engagement with the Web application. RESULTS: A total of 30 participants were enrolled. Usability ratings were generally strong, and all patients successfully built a safety plan. However, the completeness of the safety plan varied. The mean number of steps completed was 5.5 (SD 0.9) out of 6, with 90% (27/30) of participants completing at least 5 steps and 67% (20/30) completing all 6 steps. Some safety planning steps were viewed as inapplicable to some individuals. Some confusion in instructions led to modifications to improve understandability of each step. Ratings of suicide intensity after completion of the application were significantly lower than preratings, pre: mean 5.11 (SD 2.9) versus post: mean 4.46 (SD 3.0), t27=2.49, P=.02. Ratings of ability to cope with suicidal thoughts after completion of the application were higher than preratings, with the difference approaching statistical significance, pre: mean 5.93 (SD 2.9), post: mean 6.64 (SD 2.4), t27=-2.03, P=.05. CONCLUSIONS: We have taken the first step toward identifying the components needed to maximize usability of a self-administered, Web-based safety planning application. Results support initial consideration of the application as an adjunct to clinical contact. This allows for the clinician or other personnel to provide clarification, when needed, to help the patient build the plan, and to help review and revise the draft.

RESUMEN

OBJECTIVE: Dialectical behavior therapy (DBT) is an evidence-based psychosocial treatment with efficacy in reducing self-harm behaviors in borderline personality disorder (BPD). This study describes and evaluates a clinical curriculum to teach DBT to psychiatry residents, developed at a large urban university hospital. The curriculum objectives are to (1) have psychiatry residents achieve basic understanding of DBT theory and clinical skill, (2) increase residents' ability and confidence in treating self-harm behaviors (both suicidal behavior and non-suicidal self-injury), and (3) enhance residents' willingness to treat individuals with BPD. METHODS: In addition to a 6-week didactic course on DBT offered to all residents (n = 62), 25 elected to enroll in a year-long DBT clinical training curriculum over the course of a 5-year period. The DBT clinical training consisted of 15 h of additional didactics, ongoing conduct of individual therapy and group DBT skills training, videotaping of individual therapy sessions, and weekly supervision meetings utilizing videotape to provide feedback. Residents participating in the clinical training program videotaped baseline and later sessions, which were rated for DBT adherence. All 62 graduates of the program were surveyed regarding the impact of the training on their practice of psychiatry. RESULTS: Upon graduation, a high percentage (87 % in the curriculum and 70 % in the didactic course only) reported incorporating DBT into their psychiatry practice, as well as willingness and confidence in treating BPD and self-harm behaviors. Residents participating in the clinical training demonstrated significant improvement in their ability to utilize DBT interventions, particularly in structuring sessions, problem assessment, problem solving, and using validation and dialectical strategies. CONCLUSION: This DBT curriculum was effective in preparing psychiatrists-in-training to incorporate evidence-based practices for effective treatment of BPD and self-harm behaviors and can serve as a model for teaching DBT during psychiatry residency training. Limitations include a small sample size and lack of baseline survey measurement of attitudes for pre- and post-curriculum comparison.

RESUMEN

Emergency departments (ED) are prime locations for identifying individuals at high risk of suicide and for making life-saving interventions. In an ideal scenario, all ED patients at risk of suicide could be identified and connected with effective, feasible interventions, and this would occur in a supportive system not overburdened by screening or assessment requirements. In this review, we focus on challenges to achieving this ideal--along with potential solutions--at the level of patients, providers, the ED environment, and the larger health care system.

RESUMEN

Suicide attempters differ in the degree of planning for their suicide attempts. The purpose of this study was to identify differences between individuals who make planned (≥3 hours of planning) and unplanned (<3 hours of planning) suicide attempts. Depressed suicide attempters (n = 110) were compared based on degree of planning of their most recent suicide attempt on demographic and clinical variables. Participants who made planned suicide attempts were more likely to have family history of completed suicide, more severe and frequent suicidal ideation, greater trait impulsivity, and greater suicidal intent and more severe medical consequences for both their most recent and most serious suicide attempts. These results suggest clear clinical differences based on the degree of suicide attempt planning. Severe suicidal ideation, high suicide intent, family history of suicide completion, and high levels of motor impulsivity contribute to a phenotype that is at greater risk of planned, highly lethal suicide attempts.
