Reasoning, problem solving, attention/vigilance, and working memory are candidate phenotypes of non-suicidal self-injury in Chinese Han nationality. Neurosci Lett 2021; 753:135878. [PMID: 33823235 DOI: 10.1016/j.neulet.2021.135878] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2021] [Revised: 03/06/2021] [Accepted: 03/31/2021] [Indexed: 01/10/2023]
Abstract
BACKGROUND Non-suicidal self-injury (NSSI) is an act of deliberately hurting one's body without the purpose of death. Internal phenotypes have been used in numerous studies of mental disorders, suicide, and self-injury. This research aimed to evaluate the cognitive function of patients with NSSI and determine their potential endophenotype. METHODS This study used a comparative control design and included 61 patients with NSSI, 55 healthy siblings (HS), and 53 healthy controls. Visual learning, reasoning and problem, verbal learning, attention/vigilance, working memory, and speed of processing were used to evaluate the cognitive function of the subjects. RESULTS Patients with NSSI and their HS showed cognitive defects in reasoning and problem, attention/vigilance, and working memory. Substantial differences were observed in verbal learning among the three groups, but no significant difference was recorded in the scores in Brief Assessment of Cognition in Schizophrenia. CONCLUSIONS The results suggest that reasoning and problem, attention/vigilance, and working memory may be potential endophenotypes in early identification of Chinese Han people with NSSI behavior.

Abstract
IMPORTANCE The weeks following discharge from psychiatric hospitalization are the highest-risk period for suicide attempts. Real-time monitoring of suicidal thoughts via smartphone prompts may be more indicative of short-term risk than a single, cross-sectional assessment. OBJECTIVE To test whether modeling dynamic changes in real-time suicidal thoughts during psychiatric hospitalization can improve predictions of postdischarge suicide attempts vs using only baseline (ie, admission) data or using the mean level of real-time suicidal thoughts during hospitalization. DESIGN, SETTING, AND PARTICIPANTS In this prognostic study, 83 adults recruited from the inpatient psychiatric unit at Massachusetts General Hospital completed ecological momentary assessment surveys of suicidal thinking 4 to 6 times per day during hospitalization as well as brief follow-up surveys assessing suicide attempts at 2 and 4 weeks after discharge. Participants completed at least 3 real-time monitoring surveys. Inclusion criteria included hospitalization for suicidal thoughts and/or behaviors and English fluency. Data were collected from January 2016 to December 2018 and analyzed from January to December 2020. MAIN OUTCOMES AND MEASURES The primary outcome was suicide attempt in the month after discharge. RESULTS Of 83 participants (mean [SD] age, 38.4 [13.6] years; 43 [51.8%] male participants; 69 [83.1%] White individuals), 9 (10.8%) made a suicide attempt in the month after discharge. Mean cross-validated AUC for elastic net models revealed predictive accuracy was fair for the model using baseline data (area under the curve [AUC], 0.71; first to third quartile, 0.55-0.88), good for the model using the mean level of real-time suicidal thoughts during hospitalization (AUC, 0.81; first to third quartile, 0.67-0.91), and best for the model using dynamic changes in real-time suicidal thoughts during hospitalization (AUC, 0.89; first to third quartile, 0.81-0.97); this pattern of results held for other classification metrics (eg, accuracy, positive predictive value, Brier score) and when using different cross-validation procedures. Features assessing rapid fluctuations in suicidal thinking emerged as the strongest predictors of posthospital suicide attempts. A final set of models incorporating percentage missingness further improved both the mean (mean AUC, 0.93; first to third quartile, 0.90-1.00) and dynamic feature (mean AUC, 0.93; first to third quartile, 0.88-1.00) models. CONCLUSIONS AND RELEVANCE In this study, collecting real-time data about suicidal thinking during the course of hospitalization significantly improved short-term prediction of posthospitalization suicide attempts. Models including dynamic changes in suicidal thinking over time yielded the best prediction; features that captured rapid changes in suicidal thoughts were particularly strong predictors. Survey noncompletion also emerged as an important predictor of posthospitalization suicide attempts.

J Affect Disord 2020; 273:597-603. [PMID: 32560959 DOI: 10.1016/j.jad.2020.05.072] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 05/12/2020] [Accepted: 05/14/2020] [Indexed: 12/22/2022]
Abstract
BACKGROUND Deliberate self-harm (DSH) is often recurrent, but the reported rate of short-term repetition of DSH has varied greatly. This systematic review and meta-analysis aim to synthesize findings through providing pooled rate estimates and to explore their differences by age, gender, and other factors. METHODS A comprehensive search of PubMed, Web of Science, EMBASE, and PsycINFO was conducted to include longitudinal studies from 1999 to 2018. Random effects model was applied to pool rates of non-fatal and fatal repetition at 0.5, 1, 2, and 3 years intervals. RESULTS Of 9201 potentially eligible articles 76 studies were included for this systematic review and meta-analysis. The pooled rates of non-fatal repetition were 15.01%, 17.03%, 20.82%, and 24.20% during the 0.5-year, 1-year, 2-year, and 3-year follow-up, respectively. The corresponding rates of fatal repetition were 0.77%, 1.34%, 1.49% and 2.46%, respectively. When focusing on the 1-year follow-up, the pooled rate of fatal, not non-fatal, repetition was significantly higher in males than females. The rate of non-fatal DSH repetition was highest in middle-aged adults, while the rate of fatal repetition was highest among the elderly. Geographically, Europe had higher rate of non-fatal repetition whilst Asia had higher rate of repetition leading to death. LIMITATION Search was limited to English language and publication bias was observed. CONCLUSIONS Both non-fatal and fatal repetitions are common among people with DSH, but the rates differ considerably by gender, age and geographical location. These insights may guide provision of follow-up care and effort of suicide prevention for this high-risk population.

Hopelessness is associated with repeated suicidal behaviors after discharge in patients admitted to emergency departments for attempted suicide. J Affect Disord 2020; 272:170-175. [PMID: 32379612 DOI: 10.1016/j.jad.2020.04.037] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2020] [Revised: 04/03/2020] [Accepted: 04/24/2020] [Indexed: 01/03/2023]
Abstract
BACKGROUND Hopelessness may be associated with an increased risk of suicide. However, findings regarding the long-term predictive ability of the Beck Hopelessness Scale (BHS) for suicide are inconsistent. This study investigated the long-term predictive ability of BHS scores for subsequent self-harm episodes in individuals admitted to an emergency department after attempting suicide. METHODS The BHS was administered to 805 adult patients with a DSM-IV-TR axis I disorder admitted to an emergency department following a suicide attempt. The patients were followed for at least 18 months and up to 5 years. The incidence of the first subsequent suicidal behavior (attempt or dying by suicide) was examined and the numbers per person-year of overall repeat self-harm episodes, suicide attempt episodes, and non-suicidal self-harm episodes were evaluated. RESULTS The total BHS scores showed significant associations with the overall number of self-harm episodes per person-year (incidence rate ratio [IRR], 1.05; 95% confidence interval [CI], 1.03-1.07; p < 0.0001), the number of suicide attempt episodes per person-year (IRR, 1.05; 95%CI, 1.03-1.08; p < 0.0001), and the number of non-suicidal self-harm episodes per person-year (IRR, 1.05; 95%CI, 1.03-1.07; p < 0.0001). LIMITATIONS The study excluded children and adolescents. The sample size, while large, was insufficient to ensure generalizability, or to allow subanalyses based on specific disorders. CONCLUSIONS Hopelessness scores assessed in the emergency department after a self-harming episode were associated with a rate of repetition of suicidal behaviors after discharge. Additional strategies to address hopelessness of these patients are warranted.

Abstract
The One-to-One program aims to reduce criminal recidivism among prisoners shortly awaiting release, and among probationers. Of 1,484 program participants in Sweden, 776 contained adequate data for analysis. Pre- and post-program scores were available for the Alternative Thinking Test, Levenson's Locus of Control Scale, Skill Survey, Citizen Scale, and Problem Checklist, all areas addressed in the program. This study examined predictive properties of test scores and background characteristics regarding recidivism, as well as differences between sub-groups. All post-tests indicated pro-social changes. Older participants were more likely to complete the program. The most potent predictor for non-recidivism was program completion, with non-completers 64% more likely to re-offend. Significant associations occurred between recidivism and the tests measuring skill improvement over time, chance locus of control pre- and post-program, and attitudes and values (Citizen Scale), partly supporting the theory behind the program.

Abstract
The more complex influences of social problem-solving abilities and rumination-specifically brooding and reflection-on suicide intent is not well understood. We hypothesized that social problem solving would moderate the association between reflection and suicide intent, and mediate the influence of brooding on suicide intent. A convenience sample (N=186) of individuals hospitalized for recent suicide attempt was interviewed, assessing suicide intent, social problem solving, brooding, reflection and depression. Brooding and reflection were positively associated with suicide intent. The mediating, but not the moderating, hypothesis was supported. Brooding was not significant (β=0.15, t=1.92, p=0.06) with social problem solving controlled. Interventions to disengage rumination and improve social problem-solving skills are underscored.

Abstract
BACKGROUND Prediction of self-harm is limited clinically. Early identification of individuals likely to repeat self-harm could improve outcomes and reduce suicide risk. Various neurocognitive deficits have been found in people who self-harm, but the ability of these to predict repetition has yet to be established AIMS: Identify neurocognitive factors that may predict repetition of self-harm. METHODS Systematic narrative review of English language publications assessing neurocognitive functioning and self-harm repetition, searching multiple databases from inception to March 2015. Quality of studies was appraised. A narrative synthesis was performed. RESULTS 7026 unique records were identified, and 169 full-texts assessed. 15 unique studies provided data. No imaging studies could be included. Most studies assessed cognitive control or problem solving, but neither factor was consistently associated with repetition. However, specific tasks may show promise. Two studies in adolescents suggest that value-based decision-making impairments could be predictive of repetition. There were too few results for memory to draw specific conclusions. CONCLUSIONS Selected studies suggest promise for particular neurocognitive factors and specific cognitive tasks in terms of repetition of self-harm.

Abstract
The assessment of self-harm risk is a common, difficult, and perplexing task for many physicians, especially those working in emergency departments (ED). Attempts have been made to determine objective methods for assessing patients with suicidal ideation or self-harm though there is still a lack of knowledge about objective assessments of these patients. A study was conducted where 181 suicidal patients were enrolled in two EDs within the city of Edmonton, Canada. Initial interviews were conducted in the ED which collected basic demographics and medical history as well as psychometric measures including the Beck Hopelessness Scale, Barratt Impulsiveness Scale, Brief Symptom Inventory, Drug Abuse Screening Test 10, and CAGE questionnaire. The results of these measures were compared between those who presented to the ED with self-harm and those who presented only with ideation. Those with recent self-harm scored lower on many of the scales and subscales of distress and impulsivity measured compared to those with no recent self-harm. Possible explanations for this difference include differences in psychological traits between the two groups and possible cathartic effects of self-harm. The lower scores obtained by those that present with self-harm may complicate attempts to use psychometric tools to determine future self-harm risk.

Abstract
BACKGROUND Self-harm entails high costs to individuals and society in terms of suicide risk, morbidity and healthcare expenditure. Repetition of self-harm confers yet higher risk of suicide and risk assessment of self-harm patients forms a key component of the health care management of self-harm patients. To date, there has been no systematic review published which synthesises the extensive evidence on risk factors for repetition. OBJECTIVE This review is intended to identify risk factors for prospective repetition of self-harm after an index self-harm presentation, irrespective of suicidal intent. DATA SOURCES PubMed, PsychInfo and Scirus were used to search for relevant publications. We included cohort studies which examining factors associated with prospective repetition among those presenting with self-harm to emergency departments. Journal articles, abstracts, letters and theses in any language published up to June 2012 were considered. Studies were quality-assessed and synthesised in narrative form. RESULTS A total of 129 studies, including 329,001 participants, met our inclusion criteria. Some factors were studied extensively and were found to have a consistent association with repetition. These included previous self-harm, personality disorder, hopelessness, history of psychiatric treatment, schizophrenia, alcohol abuse/dependence, drug abuse/dependence, and living alone. However, the sensitivity values of these measures varied greatly across studies. Psychological risk factors and protective factors have been relatively under-researched but show emerging associations with repetition. Composite risk scales tended to have high sensitivity but poor specificity. CONCLUSIONS Many risk factors for repetition of self-harm match risk factors for initiation of self-harm, but the most consistent evidence for increased risk of repetition comes from long-standing psychosocial vulnerabilities, rather than characteristics of an index episode. The current review will enhance prediction of self-harm and assist in the efficient allocation of intervention resources.

Abstract
OBJECTIVES This review aimed to identify the evidence for predictors of repetition of suicide attempts, and more specifically for subsequent completed suicide. METHODS We conducted a literature search of PubMed and Embase between January 1, 1991 and December 31, 2009, and we excluded studies investigating only special populations (eg, male and female only, children and adolescents, elderly, a specific psychiatric disorder) and studies with sample size fewer than 50 patients. RESULTS The strongest predictor of a repeated attempt is a previous attempt, followed by being a victim of sexual abuse, poor global functioning, having a psychiatric disorder, being on psychiatric treatment, depression, anxiety, and alcohol abuse or dependence. For other variables examined (Caucasian ethnicity, having a criminal record, having any mood disorders, bad family environment, and impulsivity) there are indications for a putative correlation as well. For completed suicide, the strongest predictors are older age, suicide ideation, and history of suicide attempt. Living alone, male sex, and alcohol abuse are weakly predictive with a positive correlation (but sustained by very scarce data) for poor impulsivity and a somatic diagnosis. CONCLUSION It is difficult to find predictors for repetition of nonfatal suicide attempts, and even more difficult to identify predictors of completed suicide. Suicide ideation and alcohol or substance abuse/dependence, which are, along with depression, the most consistent predictors for initial nonfatal attempt and suicide, are not consistently reported to be very strong predictors for nonfatal repetition.

Abstract
OBJECTIVE To examine several potential predictive screening tools for emergency department assessment of risk of self-harm. METHODS Adult patients presenting with self-harm or suicidal ideation were enrolled at 2 emergency departments at large teaching hospitals in Edmonton, Alberta. Patients completed a brief interview assessing demographics and psychiatric history and several questionnaires (the Beck Hopelessness Scale, the Barrett Impulsiveness Scale [BIS], and the Brief Symptom Inventory [BSI]) and drug and alcohol abuse screens (Drug Abuse Screening Test [DAST-10] and the Cut down, Annoyed, Guilt, Eye-opener [commonly referred to as CAGE] Questionnaire). At 3 months, patients were followed up via telephone and electronic health records to ascertain self-harm outcome. Questionnaires and their subscales were assessed using logistic regression. Receiver operating characteristic (ROC) analysis was performed on the results. RESULTS Among the 157 patients enrolled, 49% were women and 36% (of the total) were aged 18 to 29 years. Several of the subscales of the BSI and BIS as well as the DAST-10 were significant predictors of self-harm (P < 0.05). ROC analysis showed that none of the scales in isolation were very strong predictors. Hierarchical regression analysis that combined the significant scales with clinical risk factors that were significantly related to self-harm (that is, age, education level, history of self-harm, and whether they presented with self-harm or only suicidal ideation) indicated that the BIS and DAST-10 questionnaires each added significantly to the predictive ability of a model with these risk factors. CONCLUSIONS While many of the questionnaires and their related constructs are related to future self-harm, none of them are particularly strong and their diagnostic usefulness is limited.

Abstract
INTRODUCTION There is an urgent need to define the neurobiological and cognitive underpinnings of suicidal ideation and behavior in veterans with traumatic brain injury (TBI). Separate studies implicate frontal white matter systems in the pathophysiology of TBI, suicidality, and impulsivity. We examined the relationship between the integrity of major frontal white matter (WM) systems on measures of impulsivity and suicidality in veterans with TBI. METHODS Fifteen male veterans with TBI and 17 matched healthy controls (HC) received clinical ratings, measures of impulsivity and MRI scans on a 3T magnet. Diffusion tensor imaging (DTI) data for the genu and cingulum were analyzed using Freesurfer and FSL. Correlations were performed for fractional anisotropy (FA) (DTI) values and measures of suicidality and impulsivity for veterans with TBI. RESULTS Significantly decreased in FA values in the left cingulum (P = 0.02), and left (P = 0.02) and total genu (P = 0.01) were observed in the TBI group relative to controls. Measures of impulsivity were significantly greater for the TBI group and total and right cingulum FA positively correlated with current suicidal ideation and measures of impulsivity (P <0.03). CONCLUSION These data demonstrate a significant reduction in FA in frontal WM tracts in veterans with mild TBI that was associated with both impulsivity and suicidality. These findings may reflect a neurobiological vulnerability to suicidal risk related to white matter microstructure.

Abstract
BACKGROUND Assessment of self harm risk is both a common and difficult task in emergency room settings. Psychometric measures have been developed to help with this assessment but it is uncertain how well these measures perform and which are clinically useful for assessment in this setting. METHOD Two reviewers independently assessed studies for relevance, inclusion, and study quality. Included studies classified mostly adult patients at risk for self-harm treated in an ED. The outcome variables selected were recurrence of self-harm/suicidal ideation or hospitalization. Only cohort study designs with follow-up were eligible. RESULTS From 556 potentially relevant abstracts, 12 studies were identified for inclusion in the review. Overall, the risk of bias was considered moderate to low in this review. Of the included studies reporting future self harm as an outcome measure, only the scales that are part of the Manchester self harm project, the Implicit Associations Test and the Violence and Suicide Assessment Form were found to successfully predict self harm. The four studies that assessed admission as an outcome utilized eight different actuarial methods. Of the scales assessed, six were found to be significant predictors of admission. LIMITATIONS It was not possible to perform a meta-analysis with the studies detected and it is uncertain whether publication bias or selection bias within the reviewed studies affected the results. CONCLUSION Overall, while many methods used in the ED to assess suicidal and parasuicidal patients have strong psychometric properties, there is little clinical evidence supporting their use.

Abstract
Suicide is difficult to predict and prevent because people who consider killing themselves often are unwilling or unable to report their intentions. Advances in the measurement of implicit cognition provide an opportunity to test whether automatic associations of self with death can provide a behavioral marker for suicide risk. We measured implicit associations about death/suicide in 157 people seeking treatment at a psychiatric emergency department. Results confirmed that people who have attempted suicide hold a significantly stronger implicit association between death/suicide and self than do psychiatrically distressed individuals who have not attempted suicide. Moreover, the implicit association of death/suicide with self was associated with an approximately 6-fold increase in the odds of making a suicide attempt in the next 6 months, exceeding the predictive validity of known risk factors (e.g., depression, suicide-attempt history) and both patients' and clinicians' predictions. These results provide the first evidence of a behavioral marker for suicidal behavior and suggest that measures of implicit cognition may be useful for detecting and predicting sensitive clinical behaviors that are unlikely to be reported.
