Abstract
Although it is well established that individuals living with psychosis are at increased risk for suicidal ideation, attempts, and death by suicide, several gaps in the literature need to be addressed to advance research and improve clinical practice. This Call-to-Action highlights three major gaps in our understanding of the intersection of psychosis and suicide as determined by expert consensus. The three gaps include research methods, suicide risk screening and assessment tools used with persons with psychosis, and psychosocial interventions and therapies. Specific action steps to address these gaps are outlined to inform research and practice, and thus, improve care and prognoses among persons with psychosis at risk for suicide.

Abstract
INTRODUCTION Individuals with schizophrenia are at increased risk for suicide, and the Demoralization Hypothesis states that non-delusional awareness of one's social, cognitive, or occupational deterioration elicits depression and hopelessness. Both depression and hopelessness are established risk factors for suicide and are features of schizophrenia. The present study investigated whether insight into one's schizophrenia yields suicidal ideation, specifically by way of thwarted belongingness and perceived burdensomeness, which are constructs related to demoralization and measured by the Interpersonal Needs Questionnaire (INQ). METHODS Three separate models explored the mediating role of INQ scores on suicidal ideation in 99 participants with schizophrenia. With suicidal ideation entered as the dependent variable and INQ scores entered as the mediator, the first model included insight as the independent variable, the second included cognitive functioning, and the third included cognitive deterioration post-illness-onset. RESULTS Consistent with our hypothesis, INQ scores related to suicidal ideation (B = .03, SE = .01, p < .001). However, neither insight, cognitive functioning, nor cognitive deterioration predicted INQ scores or suicidal ideation. Additionally, INQ scores did not mediate relationships with suicidal, ideation. CONCLUSION Although INQ scores led to increased suicidal ideation, neither insight into illness, current cognitive functioning, nor shift in functioning led to increased INQ scores. Implications are discussed, and future directions are proposed.

Abstract
BACKGROUND Insomnia is common in patients with schizophrenia, which contributes to worsening psychiatric symptoms and suicidality. We aimed to assess the inter-relationships of insomnia and psychopathology with suicidal ideation (SI) among 1407 Chinese patients with chronic schizophrenia via the network approach. METHOD We used Positive and Negative Syndrome Scale, Insomnia Severity Index, and Beck Scale for Suicidal Ideation to assess psychiatric symptoms, insomnia, and SI, respectively. Lifetime suicidal attempts (SA) were collected. RESULTS (1) The incidence of insomnia, lifetime SI, lifetime SA, and current SI was 13.5% (n = 190), 22.8% (n = 321), 13.5% (n = 190), and 9.7% (n = 136), respectively. (2) Patients with insomnia had worse clinical symptoms and higher suicidal risk. (3) Daytime dysfunction, sleep-related distress, conceptual disorganization, delusions, anxiety, and poor rapport were the core symptoms, while late sleep onset and sleep dissatisfaction emerged as bridge symptoms connecting insomnia and psychopathology. (4) Depressive mood, hallucinations, poor impulse control, guilty feelings, insomnia-related impaired quality of life, and sleep dissatisfaction were directly associated with SI. CONCLUSION Our findings called for formal assessment of insomnia in patients with schizophrenia, which should cover both nocturnal and daytime insomnia symptoms. Targeted interventions for key symptoms may help reduce insomnia, psychiatric symptoms, and SI in patients with schizophrenia.

Abstract
BACKGROUND Suicide rates in adolescents with major depressive disorder (MDD) change with age and gender. Early adulthood is an important transitional stage between late adolescence and adulthood, in which an individual's mind gradually matures. However, there are fewer studies on prevalence and variables linked to the suicide attempts of young adults with MDD. AIMS To explore gender differences in the prevalence and risk factors associated with suicide attempts in young adults with first-episode drug-naive MDD. METHOD The Hamilton Rating Scale for Depression (HRSD), Hamilton Rating Scale for Anxiety (HRSA) and Positive Subscale of the Positive and Negative Syndrome Scale (PANSS) were used to assess depression, anxiety and psychotic symptoms respectively and various biochemical indicators were assessed. RESULTS Among 293 young adults with first-episode drug-naive MDD, the prevalence of suicide attempts was 15.45% (19/123) for males and 14.12% (24/170) for females. Males with suicide attempts had higher levels of thyroid-stimulating hormone (TSH) and higher PANSS Positive Subscale scores, whereas females with suicide attempts had higher TSH, serum total cholesterol, fasting blood glucose and diastolic blood pressure levels and higher scores on the HRSD, HRSA, PANSS Positive Subscale (all Bonferroni corrected P < 0.05). In males, PANSS Positive Subscale score (B = 0.17, P = 0.03, OR = 1.19, 95% CI 1.02-1.38) was a risk factor for suicide attempts. CONCLUSIONS There were significant gender differences in the risk factors for suicide attempts in young adults with first-episode drug-naive MDD.

Association between early suicidal trajectories in first-episode psychosis and 10-year follow-up: TIPS registry-linked study. Lancet Psychiatry 2023; 10:528-536. [PMID: 37353264 DOI: 10.1016/s2215-0366(23)00156-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 04/24/2023] [Accepted: 04/27/2023] [Indexed: 06/25/2023]
Abstract
BACKGROUND Although the risk of suicidality is high in first-episode psychosis, patterns and individual variability in suicidal thoughts and behaviours over time are under-researched. We aimed to identify early trajectories of suicidality over a 2-year follow-up, assess their baseline predictors, and explore associations between those trajectories and later suicidality. METHODS This longitudinal follow-up study was a part of the Early Treatment and Intervention in Psychosis (TIPS)study. Participants, linked to Norwegian and Danish death registries, were recruited from four catchment areas (665 000 inhabitants) in Norway and Denmark (both inpatient and outpatient). We included participants aged 15-65 years, with an intelligence quotient of more than 70, willing to give informed consent, and with a first episode of active psychotic symptoms. Individuals with comorbid neurological or endocrinal disorders, or those with contraindications to antipsychotics, were excluded. Growth mixture modelling was used to identify trajectories of suicidal thoughts and behaviours over the first 2 years. Multinomial logistic regression was applied to examine the baseline predictors of those trajectories and their associations with suicidality at 10-year follow-up. FINDINGS A total of 301 participants were recruited from Jan 1, 1997, to Dec 31, 2000. Of the 299 with completed suicidality data at baseline, 271 participated in 1-year follow-up, 250 in 2-year follow-up, 201 in 5-year follow-up, and 186 at 10-year follow-up. At baseline, 176 (58%) were male, 125 (42%) were female. The mean age was 27·80 years (SD 9·64; range 15-63). 280 (93%) participants were of Scandinavian origin. Four trajectories over 2 years were identified: stable non-suicidal (217 [72%]), stable suicidal ideation (45 [15%]), decreasing suicidal thoughts and behaviours (21 [7%]), and worsening suicidal thoughts and behaviours (18 [6%]). A longer duration of untreated psychosis (odds ratio [OR] 1·24, 95% CI 1·02-1·50, p=0·033), poorer premorbid childhood social adjustment (1·33, 1·01-1·73, p=0·039), more severe depression (1·10, 1·02-1·20, p=0·016), and substance use (2·33, 1·21-4·46, p=0·011) at baseline predicted a stable suicidal ideation trajectory. Individuals in the stable suicidal ideation trajectory tended to have suicidal thoughts and behaviours at 10-year follow-up (3·12, 1·33-7·25, p=0·008). Individuals with a worsening suicidal trajectory were at a higher risk of death by suicide between 2 and 10 years (7·58, 1·53-37·62, p=0·013). INTERPRETATION Distinct suicidal trajectories in first-episode psychosis were associated with specific predictors at baseline and distinct patterns of suicidality over time. Our findings call for early and targeted interventions for at-risk individuals with persistent suicidal ideation or deteriorating patterns of suicidal thoughts and behaviours, or both.

Abstract
Rapid assessment and intervention of suicide risk are common and challenging in psychiatric emergency departments (PED). It is unclear whether distinct pathophysiological processes exist among depressive patients with suicidality. This study examined the network structures of biomarkers on Hypothalamic-Pituitary-Adrenal (HPA) axis, such as Adrenocorticotropic hormone (ACTH) and Corticosterone (Cort), as well as suicidality and depressive symptoms in mood disorder patients in PED. Mood disorder patients in PED were assessed with the measurements of suicidality and depressive symptoms, respectively. A network analysis was performed to identify central symptoms and bridge symptoms of this network and their links to ACTH and Cort. Network stability was examined using the case-dropping procedure. The Network Comparison Test (NCT) was conducted to evaluate whether network characteristics differed by gender. A total of 1815 mood disorder patients were recruited. The prevalence of SI was 31.2% (95% CI: 28.15-34.21%), SP was 30.4% (95% CI: 27.39-33.41%), SA was 30.62% (95% CI: 27.61-33.64%) among psychiatric outpatients. The mean score of HAMD-24 was 13.87 ± 8.02. Network analysis revealed that 'Somatic anxiety' had the highest expected centrality, followed by 'Hopelessness' and 'Suicide attempt'. 'Corticosterone' and 'Retardation' may be the main bridge symptoms between depressive symptoms and the suicidality community. The network model showed a high degree of stability. Gender did not significantly influence the network structure. The central symptoms and key bridge symptoms identified could be potential targets for interventions of the HPA axis, which is designed for regular screening of a range of suicidal activity. In the light of this, timely treatment should be provided for psychiatric emergency care.

Abstract
Suicidal ideation (SI) is common among people with schizophrenia. However, it has received less attention than suicide attempts (SA), especially in the Chinese population. Alexithymia is a well-established risk factor for SI across different populations. Nevertheless, very few studies evaluated their relationship in schizophrenia patients. We aimed to determine the prevalence and clinical correlates of SI and its relationship with alexithymia in 812 Chinese chronic schizophrenia inpatients. We assessed SI, clinical symptoms, and alexithymia by the Beck Scale for Suicidal Ideation, the Positive and Negative Syndrome Scale (PANSS), and the Toronto Alexithymia Scale, respectively. A multiple logistic regression model was conducted to identify independent correlates of SI. Receiver operating characteristic (ROC) curves and area under the curve (AUC) were performed to determine the ability of our model to distinguish between patients with and without SI. 10% (n = 84) reported current SI. Lifetime SA (OR, 4.68; 95% CI 2.76-7.94, p < 0.001), PANSS depressive factor (OR, 1.24; 95% CI 1.12-1.38, p < 0.001), PANSS positive subscale (OR, 1.055; 95% CI 1.004-1.108, p = 0.035), and difficulty identifying emotions (OR, 1.07; 95% CI 1.03-1.12, p = 0.002) were associated with SI. The AUC value was 0.80, indicating excellent distinguishing capabilities. Timely assessments of these factors may help identify schizophrenia patients who are at risk for SI.

Abstract
Background In schizophrenia, the relationship between suicide and cognition is unclear. We aimed to assess cognitive functions and insight in schizophrenia patients with and without suicide attempts. Methods In our study consisting of 77 patients, 36 of the patients had attempted suicide at least once in their lives and the remaining 41 had never attempted suicide. Sociodemographic data scale, Beck Cognitive Insight Scale, and Cambridge Neurophysiological Assessment Battery were applied. Results In this study, patients with schizophrenia who attempted suicide had higher Beck Cognitive Insight Scale self-reflectiveness scores (P = .004), lower Beck Cognitive Insight Scale self-certainty scores (P = .040), and higher Beck Cognitive Insight Scale total score (P = .004). Delay aversion (P = .003) and risk-taking scores (P = .044) of Cambridge Neurophysiological Assessment Battery Cambridge gambling task were higher in patients who attempted suicide. In logistic regression analysis, as independent factors, the number of hospitalizations increased the risk of suicide 1.5 times per hospitalization (P = .021), Cambridge gambling task delay aversion increased the risk of suicide 8.4 times per score (P = .044), and the Beck Cognitive Insight Scale self-certainty score was shown as the factor that decreased the risk of suicide by 0.78 times (P = .024). Conclusion The causes of suicide attempts in schizophrenia still preserve its uncertainty. Our results proposed a statistically significant relationship between cognitive insight and increased suicide attempts. This study also sustains that cognitive impulsivity is associated with suicidal behavior in patients with schizophrenia.

This study aims to identify the cognitive performance of suicidal and homicidal behaviors in people with schizophrenia spectrum disorders, as well as examining whether there are shared neuropsychological mechanisms. A systematic review of the recent literature was carried out from September 2012 to June 2022 using the Medline (via PubMed), Scopus, Embase, and Cochrane databases. Among the 870 studies initially identified, 23 were finally selected (15 related to suicidal behaviors and 8 to homicidal behaviors). The results evidenced a relationship between impairment of cognitive performance and homicidal behavior; meanwhile, for suicidal behaviors, no consistent results were found. High neuropsychological performance seems to act as a protective factor against violent behavior in people with schizophrenia spectrum disorders, but not against suicidal behavior; indeed, it can even act as a risk factor for suicidal behavior. To date, there is insufficient evidence that shared neurocognitive mechanisms exist. However, processing speed and visual memory seem to be affected in the presence of both behaviors.

Abstract
Suicide risk and auditory hallucinations are common in schizophrenia, but less is known about its associations. This cross-sectional study aimed to determine whether the presence and severity of auditory hallucinations were associated with current suicidal ideation or behavior (CSIB) among patients with schizophrenia. We interviewed 299 individuals with schizophrenia and acute symptoms and reviewed their medical records. Measurement included the Psychotic Symptom Rating Scale (PSYRATS-AH), the Calgary Depression Scale for Schizophrenia (CDSS), and the Positive and Negative Syndrome Scale. Logistic regression and path analysis were used. The CSIB prevalence was higher among patients with current auditory hallucination than those without (19.5% vs. 8.6%, crude odds ratio = 2.58, p = .009). Lifetime auditory hallucination experience (adjusted odds ratio [AOR] = 3.81; 95% CI: 1.45-10.05) or current auditory hallucination experience (AOR = 3.22; 95% CI: 1.25-8.28) can elevate the likelihood of CSIB while controlling for depressive symptoms and lifetime suicide-attempt history. Among those with auditory hallucinations, the emotional score of the PSYRATS-AH was positively associated with the CDSS score and there was a small indirect effect of the CDSS score on the association between the emotional domain score and CSIB (bias-corrected 95% CI, 0.02-0.20). In conclusion, the presence of auditory hallucinations was strongly associated with CSIB, independent of depressive symptoms and lifetime suicide attempts. Suicide risk assessment should consider auditory hallucination experience and patients' appraisal of its emotional characteristics. Future cohort studies are necessary to provide more conclusive evidence for the mediating pathways between auditory hallucinations and CSIB.HIGHLIGHTSThe presence of auditory hallucinations was associated with current suicidality.Auditory hallucinations' emotional severity was related to depressive symptoms.The severity of auditory hallucination was not directly associated with suicidality.

Abstract
Abnormalities in subcortical brain structures may reflect higher suicide risk in mood disorders, but less is known about its associations for schizophrenia. This cross-sectional imaging study aimed to explore whether the history of suicide attempts was associated with subcortical changes among individuals with schizophrenia. We recruited 44 individuals with schizophrenia and a history of suicide attempts (SZ-SA) and 44 individuals with schizophrenia but without a history of suicide attempts (SZ-NSA) and 44 healthy controls. Linear regression showed that SZ-SA had smaller volumes of the hippocampus (Cohen's d = -0.72), the amygdala (Cohen's d = -0.69), and some nuclei of the amygdala (Cohen's d, -0.57 to -0.72) than SZ-NSA after adjusting for age, sex, illness phase, and intracranial volume. There was no difference in the volume of the subfields of the hippocampus. It suggests the history of suicide attempts is associated with subcortical volume alterations in schizophrenia.

Abstract
INTRODUCTION Suicidal behaviour is particularly frequent in patients with psychosis. Therefore, prevention is a key objective of mental health policies. The aim of the current work is to systematically review the association between neurocognitive functioning and suicidal behaviour in patients with first-episode psychosis (FEP). MATERIAL AND METHODS Of the 3051 studies reviewed, only 7 met the inclusion criteria. Documents in English from their earliest date of coverage until January 2022 were searched for in the following databases: PubMed, Science Direct, Web of Science, Cochrane Library, PsycINFO (ProQuest), and Springerlink. We used the PICO strategy to collect and categorize the data from each selected manuscript. RESULTS Overall, the results showed that the risk of suicidal behaviour is higher for FEP patients in the presence of a number of factors: poorer general neuropsychological functioning (except for working memory), poorer social cognition, more depressive symptoms, longer duration of untreated psychosis, higher awareness of the illness, poorer premorbid adjustment, and more frequent cannabis use. DISCUSSION Comprehensive general neuropsychology and assessment of social cognition, together with routine clinical record keeping, may help to identify FEP patients at a greater risk of attempting suicide.

Abstract
BACKGROUND Suicide is one of the leading causes of death in people with schizophrenia. Identifying risk factors for suicide in schizophrenia is therefore an important clinical and research priority. METHOD A cross-sectional secondary analysis was conducted on the DNA Polymorphisms in Mental Illness Study (DPIM) data. Suicidality data was extracted, and the number of positive and negative symptoms were established for a total of 1494 participants. Logistic and negative binomial regression analyses were conducted to assess for associations between positive or negative symptoms and suicidal ideation, attempt, or number of attempts, whilst adjusting for potential confounders. RESULTS Negative symptoms were associated with a reduction in the risk of suicidal ideation (odds ratio [OR]: 0.83; 95 % CI: 0.75-0.91) and suicide attempt (OR: 0.79; 95 % CI: 0.71-0.88) after adjusting for age and sex. Positive symptoms were associated with an increased risk of suicidal ideation (OR: 1.06; 95 % CI: 1.03-1.09), suicide attempt (OR: 1.04; 95 % CI: 1.00-1.07) and number of suicide attempts (incidence rate ratio [IRR]: 1.05; 95 % CI: 1.01-1.08). Further adjusting for depressive symptoms slightly increased the magnitude of associations with negative symptoms but attenuated associations between positive symptoms and suicidality to the null. CONCLUSIONS Negative symptoms are associated with a reduced risk of suicidality, whilst positive symptoms are associated with an increased risk of suicidality. Depressive symptoms may confound or mediate these associations.

Abstract
OBJECTIVES Patients with schizophrenia have a significant risk of self-harm. We aimed to explore the dynamic relationship between symptomatology, functioning and deliberate self-harm (DSH) and evaluate the feasibility of developing a self-harm risk prediction tool for patients with first-episode schizophrenia (FES). METHODS Patients with FES (n = 1234) were followed up for 36 months. Symptomatology, functioning, treatment adherence and self-harm information were obtained monthly over the follow-up period. A time-varying vector autoregressive (VAR) model was used to study the contribution of clinical variables to self-harm over the 36th month. Random forest models for self-harm were established to classify the individuals with self-harm and predict future self-harm events. RESULTS Over a 36-month period, 187 patients with FES had one or more self-harm events. The depressive symptoms contributed the most to self-harm prediction during the first year, while the importance of positive psychotic symptoms increased from the second year onwards. The random forest model with all static information and symptom instability achieved a good area under the receiver operating characteristic curve (AUROC = 0.77 ± 0.023) for identifying patients with DSH. With a sliding window analysis, the averaged AUROC of predicting a self-event was 0.65 ± 0.102 (ranging from 0.54 to 0.78) with the best model being 6-month predicted future 6-month self-harm for month 11-23 (AUROC = 0.7). CONCLUSIONS Results highlight the importance of the dynamic relationship of depressive and positive psychotic symptoms with self-harm and the possibility of self-harm prediction in FES with longitudinal clinical data.

Clinical insight and cognitive functioning as mediators in the relationships between symptoms of psychosis, depression, and suicide ideation in first-episode psychosis.

Abstract
First-episode psychosis (FEP) is a particularly high-risk period for suicide. Literature suggests poor cognitive functioning may serve as a protective factor, while investigations of clinical insight reveal a complex relationship with suicide outcomes. This study examined the mediating role of cognition and clinical insight in the relationships between positive and negative symptoms, depression, and subsequent suicide ideation among individuals in FEP. Data were obtained from the Recovery After an Initial Schizophrenia Episode project. Participants (n = 404) included adolescents and adults in FEP between the ages of 15 and 40. Measurement utilized the Calgary Depression Rating Scale, Positive and Negative Syndrome Scale, and Brief Assessment of Cognition in Schizophrenia. Structural equation modeling was used to examine the mediation model. The likelihood of experiencing suicide ideation was significantly decreased when working memory was stronger (b = -0.034, SE = 0.02, OR = 0.967, p < .05), and significantly increased when clinical insight was stronger (b = 0.191, SE = 0.08, OR = 1.21, p < .01), positive symptoms were greater (b = 0.422, SE = 0.20, OR = 1.52, p < .05) and depressive symptoms were greater (b = 0.545, SE = 0.15, OR = 1.70, p < .001). Clinical insight and working memory functioned as mediators in the relationships between depression, positive symptoms, negative symptoms, and suicide ideation. Findings suggest it is essential that clinicians have awareness of insight being a risk factor for suicide ideation and balance therapeutic efforts to strengthen clinical insight and cognition in psychosocial treatments with suicide risk assessment and prevention methods.

Abstract
BACKGROUND The prevalence of suicidal ideation (SI) and behavior (SB) among people suffering from psychotic disorders is a public health issue. Most suicide attempts (SAs) occur before or during the early phases of first-episode psychosis (FEP). Improving knowledge about the suicide risk in the early stages is essential to develop therapeutic and prevention strategies. We conducted a systematic review to investigate an association between neurocognitive impairments or a history of impulsive behavior and SI or SB among patients with FEP. METHOD PRISMA guidelines were followed. Ten databases were searched using MeSH terms or key-words related to FEP, impulsivity or cognitive functioning measures and SI or SB, without restrictions for study design or length of follow-up. Included studies evaluated at least one cognitive function with neuropsychological tests or validated questionnaires, or provided records of impulsive behavior. RESULTS Twenty one research papers were included from databases, bibliographic references or expert opinions. Among patients with FEP, seven studies showed more pronounced neuropsychological impairments, especially regarding attention, processing speed, executive functioning and theory of mind in patients that had attempted suicide. No association was found between cognitive impairments on neuropsychological tests and SI. Previous non-suicidal impulsive behaviors were associated with SAs and suicide. CONCLUSION Our review suggests an association between neurocognitive impairments and SAs among patients with FEP. Records of impulsive behavior are also associated with SB in that population. Further research on the neuropsychology of FEP is necessary to identify how these impairments facilitate SB and evaluate their potential utility as therapeutic targets.
