Trajectories of suicidal ideation in patients with first-episode psychosis: secondary analysis of data from the OPUS trial

Trajectories of suicidal risk among individuals with first-episode psychosis: Relationship to recovery and symptoms

This study examined trajectories of suicide-risk and their relationship to symptoms, recovery, and quality of life over time. Data was obtained from the Recovery after an Initial Schizophrenia Episode Early Treatment Program (RAISE-ETP) study. 404 individuals with first-episode psychosis (FEP) completed measures of suicide-risk, depression, positive symptoms, recovery, and quality of life at baseline, 6mo, 12mo, 18mo, and 24mo. Latent class analysis was used to identify temporal trajectories of suicide-risk. General linear mixed models for repeated measures were used to examine the relationship between the latent trajectories of suicide-risk and clinical variables. Results identified three latent trajectories of suicide-risk (low-risk, worsening, and improving). The low-risk and improving classes experienced improvements in depression, positive symptoms, quality of life, and recovery over time. The worsening class experienced improvements in positive symptoms and quality of life, but no change in depression or recovery. These results suggest that some individuals with FEP are at risk for persistent depression and worsening suicide-risk during treatment despite experiencing improvements in positive symptoms and quality of life. These findings have important clinical implications, as persistent depression and worsening suicide-risk might be masked by the primary focus on positive symptoms and quality of life in most FEP clinics.

Heterogeneity in the Course of Suicidal Ideation and its Relation to Suicide Attempts in First-Episode Psychosis: A 5-Year Prospective Study

OBJECTIVES

Although the risk of suicide is high in first-episode psychosis (FEP), little is known about the course of suicidal ideation and its relation to suicide attempts. Therefore, we aimed to identify 5-year trajectories of suicidal ideation and associated factors in FEP and compare how suicide attempts were distributed across these identified trajectories.

METHOD

This 5-year prospective study assessed suicidal ideation, suicide attempts and potentially associated factors through research interviews, chart review and coroners' reports in 382 FEP patients [mean age = 23.53 (SD = 3.61)] admitted to 2 5-year early psychosis services in Montreal, Canada. Trajectories were identified using a semiparametric mixture model, and associated factors with multinomial logistic regression.

RESULTS

Three suicidal ideation trajectories were identified: low and decreasing (n = 325, 85.08%); early decline, then increasing (n = 30, 7.85%), and persistent suicidal ideation (n = 27, 7.07%). Suicidal ideation prior to admission (OR = 2.85, 95% CI, 1.23 to 6.63, P < 0.05) and cocaine use disorder (OR = 6.78, 95% CI, 1.08 to 42.75, P < 0.05) were associated with the early decline, then increasing suicidal ideation trajectory. Persons with prior suicide ideation (OR = 4.33, 95% CI, 1.66 to 11.29, P < 0.05) and attempts (OR = 8.18, 95% CI, 2.39 to 27.97, P < 0.001) and alcohol use disorder (OR = 3.63, 95% CI, 1.4 to 9.42, P < 0.05) were more likely to belong to the persistent suicidal ideation trajectory, and to attempt suicide during follow-up.

CONCLUSIONS

Our study highlights heterogeneity in the course of suicidal ideation over 5 years and the importance of ongoing assessment of suicidal risk in FEP patients, particularly for patients who persistently report suicidal ideation, as they are likelier to engage in suicide attempts. Patients with factors associated with increasing or persistent suicidal ideation trajectories should be targeted for suicide prevention interventions from the early phase of follow-up. Given the small number of persons in these trajectories and the wide CIs for some factors, larger studies are however needed to further characterize who belongs in each group.

Heterogeneous trajectories of suicidal ideation among homeless youth: predictors and suicide-related outcomes

The current study examined heterogeneous trajectories of suicidal ideation among homeless youth experiencing suicidal ideation over 9 months in a randomized controlled intervention study. Suicidal homeless youth (N = 150) were randomly assigned to Cognitive Therapy for Suicide Prevention (CTSP) + Treatment as Usual (TAU) or TAU alone. Youth reported their suicidal ideation four times during a 9-month period. We also assessed pretreatment mental health, demographic information and session attendance as predictors of the subgroups, as well as suicide-related factors as outcomes at the 9-month follow-up. Growth mixture models suggested three distinct trajectory groups among youth: Fast Declining (74.7%), Chronic (19.3%), and Steadily Declining (6.0%). Youth in the Chronic group used more substances at baseline than the Steadily Declining group, were more likely to be White, non-Hispanic than the Fast Declining group, and attended more CTSP sessions than other groups. Contrastingly, youth in the Steadily Declining group all experienced childhood abuse. Finally, youth in the Chronic group showed significant higher risk for future suicide compared to those in the Fast Declining group at 9 months. Findings support the heterogeneity of treatment responses in suicide intervention among homeless youth, with implications to improve treatment efforts in this very high-risk population.

Strengthening associations between psychotic like experiences and suicidal ideation and behavior across middle childhood and early adolescence

BACKGROUND

Understanding risk factors related to suicidal ideation (SI) and suicidal behaviors (SB) in youth is important for informing prevention and intervention efforts. While it appears that psychotic-like experiences (PLEs) are strongly associated with both SI and SB at different points across the lifespan, the longitudinal nature of this relationship in middle childhood and early adolescence is understudied.

METHODS

The study used the unique longitudinal Adolescent Brain Cognitive Development Study data. Mixed effects linear models examined associations between PLEs and SI and SB over time using three time points of data from ages 9-13.

RESULTS

First, analyses indicated that endorsement of SI and SB increased as youth grew older for those with increased distressing PLEs. Analyses found evidence of bidirectional relationships between PLEs with SI and SB, with evidence that PLEs at baseline were associated with worsening SI and SB over time, including a transition from SI to SB (β = 0.032, FDRp = 0.002). Exploratory analyses showed consistent evidence for strengthened associations over time for higher delusional ideation with both SI and SB (βs > 0.04, FDRps < 0.001), and for perceptual distortions with SB (βs = 0.046, FDRp < 0.001). When accounting for general psychopathology, for SB, the strengthened associations over time was significantly stronger for PLEs (β = 0.053, FDRp < 0.001) compared to general psychopathology (β = 0.022, FDRp = 0.01).

CONCLUSIONS

The present study indicates both SI and SB show strengthened associations with PLEs over time, and that baseline PLEs may predict worsening of suicidality over time. The findings are important clarifications about the nature of the associations between youth-reported PLEs and suicidality over time.

Examining Risk Factors for Suicidality in Adolescents and Adults Experiencing Their First Episode of Psychosis

This narrative review aimed to identify the risk factors associated with suicidality in adolescents and adults with first-episode psychosis. The review included studies that examined various factors such as psychiatric, familial, and social factors, as well as previous self-harm, suicidal ideation, and comorbid mental health disorders. A comprehensive literature search was conducted across three publicly available databases (Embase, American Psychological Association PsycINFO, and PubMed) using specific search terms related to first-episode psychosis, suicide, self-harm, and children/adolescents and adults. The inclusion criteria included original articles focusing on prospective and retrospective cohort trials, with substantial data on first-episode psychosis and self-harm, measuring both suicidal intent and outcome. Non-original studies, case reports, case series, non-English-language publications, and studies examining violence and self-harm related to substance-induced psychosis were excluded. After manual screening and removing duplicate articles, 13 articles met the established criteria for inclusion in this review. Included studies adhered to similar inclusion and exclusion criteria, had long-term follow-up, and assessed outcomes at least twice. The findings suggest that depressive symptoms, substance use disorders, previous self-harm or suicidal ideation, and longer duration of untreated psychosis are associated with an increased risk of suicidality. However, insights into psychosis and premorbid intellectual functioning did not show a direct association with suicidality.

Association between early suicidal trajectories in first-episode psychosis and 10-year follow-up: TIPS registry-linked study

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.

Incidence, prevalence, and trajectories of suicidal ideation among clients enrolled in early intervention services for first episode psychosis in New York State

Knowledge on how suicidal ideation (SI) varies following first episode psychosis (FEP) onset is scarce. We identified 1-year trajectories of SI and baseline predictors of emergent SI among all 1298 clients aged 16-30 years enrolled between October 2013-December 2018 in OnTrackNY, a program providing early intervention services for FEP across New York State. Clinicians recorded baseline clinical and sociodemographic variables and quarterly assessments of SI over a one-year follow-up. We examined baseline correlates of baseline SI and of 1-year SI trajectory. Among clients not reporting baseline SI, we examined predictors of subsequent emergent SI. Baseline SI was reported by 349 (26.9 %) clients and associated with schizoaffective disorder, previous self-injurious behavior, any alcohol or substance use, higher symptom severity, poorer social functioning, and Non-Hispanic White, Asian or Hispanic ethnoracial background. Two hundred and two (15.6 % overall) clients stopped being suicidal within 6 months of follow-up. Persistent SI was reported by 147 (11.3 % overall) clients and, among clients not discharged before one year of follow-up, was associated with schizoaffective disorder, any alcohol use, being female, and being Hispanic or White Non-Hispanic. Among 949 (73.1 %) clients not reporting baseline SI, subsequent emergent SI was reported by 139 (10.7 % overall) and predicted at baseline by schizoaffective disorder, higher symptom severity, recent homelessness, and not being Hispanic. In conclusion, SI is highly prevalent and varies markedly over time among FEP early intervention clients. These results highlight the importance of ongoing assessment for SI among individuals experiencing FEP - even in the absence of baseline SI.

Longitudinal investigation of the presence of different trajectories and associated health and socio-economic determinants, for participants who report suicidal ideation within a community-based public health survey

OBJECTIVE

Given the paucity of evidence-based research investigating different suicidal ideation profiles and trajectories, this project sought to investigate health and socio-economic factors associated with the presence of suicidal ideation and changes in ideation over time.

DESIGN

Longitudinal cohort design, using logistic regression analysis.

SETTING

A public health survey was administered at two timepoints in a community setting across the North West of England. In the 2015/2016 survey, participants were recruited from high (n=20) and low (n=8) deprivation neighbourhoods. In the 2018 survey, only the 20 high-deprivation neighbourhoods were included.

PARTICIPANTS

4287 people were recruited in 2015/2016 and 3361 were recruited in 2018. The 2018 sample was subdivided into those who responded only in 2018 (n=2494: replication sample) and those who responded at both timepoints (n=867: longitudinal sample).

PRIMARY OUTCOME MEASURES

Suicide ideation was the dependent variable which was assessed using item 9 of the Patient Health Questionnaire instrument.

RESULTS

The prevalence of suicidal ideation was 11% (n=454/4319) at 2015/2016 and 16% (n=546/3361) at 2018.Replication study results highlighted: persistent debilitation from physical ill health and/or medication side effects; demographic factors (ie, middle-aged, single or never married); and personal coping strategies (ie, smoking) as risk factors for suicidal ideation. A static/improved financial position and high levels of empathy were protective factors.Longitudinal study results confirmed three suicidal ideation trajectories: 'onset', 'remission' and 'persistence'. Similar findings to the replication study were evidenced for the onset and persistence trajectories. Persistent suicidal ideation was synonymous with higher levels of practical support which may correspond to the higher levels of debilitation and functional disability reported within this group. Remission was characterised by fewer debilitating factors and higher levels of self-agency.

CONCLUSION

A greater appreciation of the heterogeneity of suicidal trajectories should lead to the implementation of broad clinical assessments and targeted interventions.

Factors associated with suicide attempts in first-episode psychosis during the first two years after onset

The risk of suicide in first-episode psychosis (FEP) is high. However, there are many unknowns about this phenomenon and the risk factors associated with higher risk are not well-understood. Therefore, we aimed to determine the baseline sociodemographic and clinical factors associated with suicide attempts in FEP patients over two-years after psychosis onset. Univariate and logistic regression analyses were performed. Between April 2013 and July 2020, 279 patients treated at the FEP Intervention Program at our hospital (Hospital del Mar, Spain) were enrolled and 267 completed the follow-up. Of these, 30 patients (11.2%) made at least one suicide attempt, mostly during the untreated psychosis period (17 patients, 48.6%). Several variables-prior history of suicide attempts and low functionality, depression, and feelings of guilt at baseline-were all significantly associated with suicide attempts. These findings suggest that targeted interventions, especially in prodromal stages, could play a key role in identifying and treating FEP patients with a high suicide risk.

Long-term trajectories of suicide ideation and its socioeconomic predictors: A longitudinal 8-year follow-up study

OBJECTIVE

Suicide ideation is the first stage of suicide behavior, and the long-term course of suicide ideation is highly variable. The aim of this study is to identify trajectories of suicide ideation over an 8-year period and explore the association of socioeconomic status (SES) with suicide ideation trajectories.

METHODS

We included 10,017 participants from Waves 7-15 of the Korea Welfare Panel Study; these have data on suicidal ideation (2012-2020). Trajectories analysis was conducted to identify distinct trajectories of suicidal ideation. Multinomial logistic regression was used to examine associations of SES with suicidal ideation trajectories. The interaction effects between current SES and prospective economic condition on trajectories were examined using a synergy index (SI).

RESULTS

We identified three suicide ideation trajectory groups: low-stable, moderate-decreasing, and high-persistent. Individuals in both moderate-decreasing and high-persistent trajectories had poorer current SES and prospective economic conditions than low-stable trajectories. Interestingly, those reporting poorer prospective economic conditions had a greater risk of being in a high-persistent trajectory than being in a moderate-decreasing trajectory. Further, individuals with poorer current SES and prospective economic conditions were more likely to be in the high-persistent trajectory.

CONCLUSIONS

Our findings demonstrated three distinct trajectories of suicide ideation which provide useful information for specific preventive interventions that could be developed. Moreover, poor prospective economic condition is a significant predictor of the high-persistent suicide ideation trajectory. Supporting economic difficulties and helping make goals and plans to strengthen positive thinking would help attenuate suicidal ideation and prevent suicidal behavior.

Prevalence of suicide ideation, self-harm, and suicide among Chinese patients with schizophrenia: a systematic review and meta-analysis

Aims

Suicide ideation, self-harm, and suicide are common in patients with schizophrenia, but the reported prevalence vary largely across studies. Improved prevalence estimates and identification of moderators of the above self-directed violence are needed to enhance recognition and care, and to guide future management and research. This systematic review aims to estimate the pooled prevalence and identify moderators of suicide ideation, self-harm, and suicide among patients diagnosed with schizophrenia in China.

Methods

Relevant articles published until September 23, 2021, were searched using PubMed, EBSCO, Web of Science, Embase, Science Direct, CNKI, CBM, VIP, and Wanfang databases. Eligible studies published in English or Chinese which reported the prevalence of suicide ideation, self-harm, or suicide among Chinese patients with schizophrenia were collected. All studies passed a quality evaluation. This systematic review was registered with PROSPERO (registration number CRD42020222338). PRISMA guidelines were used in extracting and reporting data. Random-effects meta-analyses were generated using the meta package in R.

Results

A total of 40 studies were identified, 20 of which were evaluated as high-quality studies. Based on these studies, the prevalence of lifetime suicide ideation was 19.22% (95% CI: 7.57-34.50%), prevalence of suicide ideation at the time of investigation was 18.06% (95% CI: 6.49-33.67%), prevalence of lifetime self-harm was 15.77% (95% CI: 12.51-19.33%), and prevalence of suicide was 1.49% (95% CI: 0.00-7.95%). Multivariate meta-regression analysis revealed that age (β = - 0.1517, p = 0.0006) and dependency ratio (β = 0.0113, p < 0.0001) were associated with the lifetime prevalence of self-harm. Study assessment score (β = 0.2668, p < 0.0001) and dependency ratio (β = 0.0050, p = 0.0145) were associated with the lifetime prevalence of suicide ideation. Results of the spatial analysis showed that the prevalence of self-directed violence varied greatly across different provinces.

Conclusion

This systematic review provides estimates of the prevalence of self-directed violence among Chinese patients with schizophrenia and explores its moderators and spatial patterns. Findings also have important implications for allocating prevention and intervention resources to targeted high-risk populations in high prevalence areas.

The 10-year trajectories of auditory hallucinations among 496 patients with a first schizophrenia-spectrum disorder: Findings from the OPUS cohort

BACKGROUND

Auditory hallucinations represent a key diagnostic feature of schizophrenia and one of the most frequent and debilitating psychotic symptoms. However, little is known regarding their long-term trajectories.

METHODS

We included 496 patients with a first schizophrenia-spectrum disorder. Patients were at baseline and after one, two, five, and ten years asked for auditory hallucinations, scoring from 0 ("None") to 5 ("Severe: Voices occur often every day"). We performed latent class growth analyses to identify trajectories of auditory hallucinations and multinomial logistic regression analyses to estimate predictors of trajectory membership.

RESULTS

We identified three trajectories of auditory hallucinations. The Low-Decreasing class (77%) had the lowest mean score at baseline (mean score = 2.1). The score improved within the first year (mean score = 0.5) and stayed low (mean score = 0 after ten years). The High-Fluctuating class (10%) improved during the first two years from a mean score of 3.0 to 1.0, but increased after five and ten years (mean score = 2.4). The High-Increasing class (13%) started at a high level (mean score = 3.5), improved a little after one year (mean score = 3.0), but increased to a mean score of 4.8 after ten years. Alcohol misuse and longer duration of untreated psychosis were associated with increased odds of being in the High-Increasing compared to the Low-Decreasing class.

CONCLUSIONS

The majority of patients with schizophrenia-spectrum disorder improved on auditory hallucinations during the first ten years, but almost one out of four had a fluctuating course with 13% experiencing an increase to severe and daily auditory hallucinations after ten years.

Neurocognitive functioning and impulsivity in first-episode psychosis with suicidal ideation and behavior: A systematic review

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.

A systematic review of longitudinal studies of suicidal thoughts and behaviors in first-episode psychosis: course and associated factors

PURPOSES

To better assess and reduce suicidal risk in first-episode psychosis (FEP), we aimed to investigate the evolution of suicidal thoughts and behaviors (STBs) and associated factors in FEP.

METHOD

This systematic review (PROSPERO-CRD42020168050) meets PRISMA guidelines. PubMed, Medline, PsycINFO, Embase, EBM Reviews and references lists of relevant articles were searched (February 2020) to identify longitudinal studies, published in English or in French, that assessed the prevalence of STBs at entry to services and over follow-up, and examined factors associated with STBs among all persons with affective and non-affective FEP from a defined catchment area. Screening, data extraction and quality assessment using the adapted Newcastle Ottawa Scale were done independently by two reviewers. Results on prevalence and associated factors are presented by type of STB.

RESULTS

Of 3,177 references, 17 studies of 11 non-overlapping samples (n = 14,907) with varying lengths of follow-up (1-41.7 years) were included. The prevalence of STBs decreased over follow-up. Up to 21.6% made at least one suicide attempt, 27% had suicidal ideation, and 1-4.3% died by suicide during follow-up. Of 53 factors assessed across studies, only male sex, depressive symptoms, and STBs occurring early during follow-up were associated with subsequent STBs. Early intervention for psychosis decreased STBs in the first three years. Other factors were assessed in a single study, yielded conflicting results, or were not associated with STBs.

CONCLUSIONS

The high prevalence of STBs following onset of psychosis highlights the need for early detection and intervention and ongoing assessment of suicidal risk throughout follow-up, with attention to identified risk factors. The heterogeneity of the studies precluded a meta-analysis and several factors were each assessed by a single study. Additional well-designed longitudinal studies of STBs and associated factors are warranted.

A systematic review of suicide and suicide attempts in adolescents with psychotic disorders

BACKGROUND

Suicide is the main cause of premature death in patients with psychosis. Therefore, the goal of the present study was to review suicide in adolescents with psychotic disorders by evaluating factors associated with suicidal acts. Ours is the first systematic review of suicide in this population.

METHOD

We performed a systematic review of suicide in adolescents (10 to 19 years) with psychotic disorder.

RESULTS

We identified 10 studies, only 2 of which were randomized clinical trials. The results revealed high rates of suicidal behaviour in this population: the times of higher risk were the time before admission and the period immediately following discharge. The factors most associated with suicide attempts were depression, distress with psychotic symptoms, fewer negative symptoms at baseline, positive symptoms, and anxiety disorders. Associated factors included previous psychiatric history or psychiatric admissions, female sex, prior suicidal behaviour, family history of completed suicide, and nicotine dependence.

LIMITATIONS

Clinical and methodological diversity of the studies.

CONCLUSIONS

Adolescents with psychotic disorders had a major risk of suicidal behaviour, and specific factors were associated with the act. Early detection of adolescents with psychosis is vital, since it has been found that early intervention can prevent suicidal acts in young people. However, it is necessary to perform more studies, particularly randomized controlled trials, on suicide and suicide attempts, particularly in adolescents.

Suicidality and social problem-solving skills among individuals with first-episode psychosis participating in Coordinated Specialty Care

AIM

Although suicidal ideation may decrease over the course of participation in specialized clinical programmes for first-episode psychosis (FEP), it is unclear whether such improvements exceed those that occur during treatment as usual. Clarifying the mechanisms underlying reductions in suicidal ideation and behaviour among individuals with first-episode psychosis may highlight important strategies through which specialized clinical programmes can increase the potency of their services to reduce suicidality among this high-risk population. Thus, the goal of this study is to evaluate the longitudinal relationships between suicidality and social problem-solving skills among individuals with FEP participating in Coordinated Specialty Care.

METHODS

Within-subject mediational and moderational models were applied to explore the interrelationships and longitudinal course of suicidality, social problem-solving and duration of untreated psychosis (DUP).

RESULTS

Over the first 6 months of care, individuals with FEP experienced improvements in social problem-solving skills that were found to mediate concurrent reductions in suicidality. Although longitudinal changes in social problem-solving skills were moderated by DUP, these results should be interpreted cautiously as they may stem in part from a relatively limited number of participants with longer durations of illness.

CONCLUSIONS

Improvements in social problem-solving skills during participation in CSC may facilitate reductions in suicidality. Treatments targeting suicidality among individuals with FEP may thus benefit from working to enhance social problem-solving skills among these individuals. Further research is needed to clarify if and how DUP may influence the magnitude of change in social problem-solving skills during participation in CSC.

Suicidality Over the First 5 Years of Psychosis: Does Extending Early Intervention Have Benefits?

OBJECTIVE

We aimed to investigate whether individuals with first-episode psychosis (FEP) receiving extended early intervention (EI) were less likely to experience suicidal ideation and behaviors than those transferred to regular care after 2 years of EI. Another objective was to examine the 5-year course of suicidality in FEP.

METHODS

We conducted a secondary analysis of a randomized controlled trial where 220 patients were randomized after 2 years of EI to receive extended EI or regular care for the subsequent 3 years. Suicidality was rated using the Brief Psychiatric Rating Scale. Linear mixed model analysis was used to study time and group effects on suicidality.

RESULTS

Extended EI and regular care groups did not differ on suicidality. There was a small decrease in suicidality over time, F(7, 1038) = 1.84, P = 0.077, with an immediate sharp decline within a month of treatment, followed by stability over the remaining 5 years. Patients who endorsed suicidality at entry (46.6%) had higher baseline positive, negative, and depressive symptoms. The 5-year course fell in 3 groups: never endorsed suicidality (33.9%), endorsed suicidality at low-risk levels (43.1%), and endorsed high-risk levels (23.0%). The high-risk group had a higher proportion of affective versus nonaffective psychosis diagnosis; higher baseline positive and depressive symptoms; higher 5-year mean depression scores, and fewer weeks of positive symptom remission over the 5-year course.

CONCLUSIONS

The first month of treatment is a critical period for suicide risk in FEP. Although early reductions in suicidality are often maintained, our findings make the case for sustained monitoring for suicide risk management.

Trajectories of change in depression symptoms and suicidal ideation over the course of evidence-based treatment for depression: Secondary analysis of a randomised controlled trial of cognitive behavioural therapy plus fluoxetine in young people

OBJECTIVES

Effective treatment of depression is a key target for suicide prevention strategies. However, only around one-third of young people with suicide risk respond to evidence-based treatments. Understanding the trajectory of suicidal ideation, as a marker of suicide risk, over the course of evidence-based treatment for depression might provide insight into more targeted and effective treatments.

METHODS

This is a secondary analysis of data from the multicentre Youth Depression Alleviation-Combined Treatment trial. A total of 153 young people aged 15-25 years diagnosed with major depressive disorder were randomly assigned in this double-blind, placebo-controlled trial to either cognitive behavioural therapy plus fluoxetine or cognitive behavioural therapy plus placebo. Participants were assessed for depression and suicidal ideation at baseline and at weeks 4, 8 and 12.

RESULTS

Using group-based trajectory modelling, we identified two distinct depression trajectories. The first (Improving; 54.9%; n = 83) comprised those who experienced a consistent decline in depression symptoms. The second (Persisting; 45.1%; n = 70) comprised those who, despite treatment, still had clinically significant levels of depression by the end of treatment. For suicidal ideation, we identified four distinct trajectories: Non-clinical (15.5%; n = 20), Low Improving (47.1%; n = 75), High Improving (24.8%; n = 38) and High Persisting (12.7%; n = 20). Treatment allocation was not significantly associated with trajectory membership for either depression or suicidal ideation.

CONCLUSION

Understanding the course of depression and suicidal ideation during treatment has important implications for managing suicide risk. The findings suggest that there is an identifiable group of young people for whom enhanced psychological and/or pharmacological intervention might be required to ensure a better treatment response. Specific interventions for those with suicidal ideation may also be prudent from the outset.

CLINICAL TRIAL REGISTRATION

The Youth Depression Alleviation-Combined Treatment trial was prospectively registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12612001281886).

Trajectories of suicidal ideation after first-episode psychosis: a growth mixture modeling approach

OBJECTIVE

The period immediately after the onset of first-episode psychosis (FEP) may present with high risk for suicidal ideation (SI) and attempts, although this risk may differ among patients. Thus, we aimed to identify trajectories of SI in a 2-years follow-up FEP cohort and to assess baseline predictors and clinical/functional evolution for each trajectory of SI.

METHODS

We included 334 FEP participants with data on SI. Growth mixture modeling was used to identify trajectories of SI. Putative sociodemographic, clinical, and cognitive predictors of the distinct trajectories were examined using multinomial logistic regression.

RESULTS

We identified three distinct trajectories: Non-SI trajectory (85.53% sample), Improving SI trajectory (9.58%), and Worsening SI trajectory (6.89%). Multinomial logistic regression model revealed that greater baseline pessimistic thoughts, anhedonia, and worse perceived family environment were associated with higher baseline SI followed by an Improving trajectory. Older age, longer duration of untreated psychosis, and reduced sleep predicted Worsening SI trajectory. Regarding clinical/functional evolution, individuals within the Improving SI trajectory displayed moderate depression at baseline which ameliorated during the study period, while the Worsening SI subgroup exhibited persistent mild depressive symptoms and greater functional impairment at follow-up assessments.

CONCLUSION

Our findings delineated three distinct trajectories of SI among participants with FEP, one experiencing no SI, another in which SI might depend on acute depressive symptomatology, and a last subset where SI might be associated with mild but persistent clinical and functional impairments. These data provide insights for the early identification and tailored treatment of suicide in this at-risk population.

Psychotic Experiences and Schizotypy in Early Adolescence Predict Subsequent Suicidal Ideation Trajectories and Suicide Attempt Outcomes From Age 18 to 38 Years

Subclinical risk markers for schizophrenia predict suicidality, but little is known about the nature of the relationship. Suicidal ideation is often considered homogenous, but distinguishing passive from active ideation (ie, thoughts of death vs thoughts of killing oneself) and different temporal patterns may further the understanding of risk factors. We tested whether schizotypy and psychotic experiences (PEs) in early adolescence predict subsequent growth trajectories of suicidal ideation and suicide attempt outcomes. Participants were 1037 members of the population-representative Dunedin Study cohort. PE was measured at 11 years and schizotypy at 13 and 15 years. Outcomes were passive and active suicidal ideation, and suicide attempt, measured at 18, 21, 26, 32, and 38 years. Passive ideation was best represented by 2 trajectories, including persistent and transient ideation classes. Schizotypy predicted membership in the smaller persistent class (odds ratio [OR] = 1.21, P = .041), whereas PE was not associated with class membership. The probability of suicide attempts was 13.8% in the persistent ideation class, compared with 1.8% in the transient class. Active ideation was best represented by a 1-class model, the intercept of which was predicted by schizotypy (OR = 1.23, P = .015). Suicide attempts were predicted by schizotypy (OR = 1.53, P = .040) and PE (OR = 3.42, P = .046), and this was partially mediated by indirect effects via the active ideation trajectory. Findings indicate that adolescent schizotypy and PE are related to subsequent suicidal ideation and attempts. Suicidal ideation is heterogeneous, and schizotypy is specifically related to a persistent passive ideation subgroup.

Characterization of depressed bipolar patients with current suicidal ideation

OBJECTIVE

Bipolar disorder is one of the most frequent psychiatric disorders among suicidal patients. A large part of patients with bipolar disorder (30-50%) will attempt suicide. Suicidal ideation being a major risk factor of suicidal act, it is crucial to better characterize patients with suicidal bipolar depression (i.e. depression with current suicidal ideation). The aim of this study was to characterize suicidal bipolar depressed patients in comparison with non-suicidal depressed patients in terms of clinical characteristics, evolution of depression and suicidal ideation course over time, and risk of suicide attempt during follow-up.

METHODS

Among patients with bipolar disorder recruited from the network of FondaMental expert centres for bipolar disorder between 2009 and 2017, we selected patients with at least mild depression (Montgomery-Åsberg Depression Rating Scale total score >11) and without current manic symptomatology (Young Mania Rating Scale total score <7) at baseline (N = 938). Suicidal depression was defined by a baseline score ⩾2 for item 12 of the Quick Inventory of Depressive Symptomatology-Self Report (N = 271, 28.9%). Non-suicidal depression was defined by a baseline item 12 of the Quick Inventory of Depressive Symptomatology-Self Report score <2 (N = 667, 71.1%). A subsample of about 300 patients (with or without suicidal ideation at baseline) was followed up for 2 years.

RESULTS

Baseline clinical features (e.g. depression severity, childhood trauma, global functioning) were more severe in patients with than without suicidal depression. Suicidal patients tended to remain more suicidal throughout the follow-up than patients without suicidal ideation at baseline (3.4-fold higher risk of persistent suicidal ideation at the 2-year visit despite an improvement in depressive symptomatology).

CONCLUSIONS

Depressed bipolar disorder patients reporting suicidal ideation had more severe clinical features at baseline and were more prone to report persistent suicidal ideation during the follow-up, independently of thymic state. Clinicians should closely monitor this subgroup of patients.

A Brief Mobile-Augmented Suicide Prevention Intervention for People With Psychotic Disorders in Transition From Acute to Ongoing Care: Protocol for a Pilot Trial

BACKGROUND

People with serious mental illnesses (SMIs) are at exceptionally high risk for lifetime suicidal ideation and behavior compared with the general population. The transition period between urgent evaluation and ongoing care could provide an important setting for brief suicide-specific interventions for SMIs. To address this concern, this trial, SafeTy and Recovery Therapy (START), involves a brief suicide-specific cognitive behavioral intervention for SMIs that is augmented with mobile phone interactions.

OBJECTIVE

The primary aim of this pilot trial is to evaluate the feasibility, acceptability, and preliminary effectiveness of the intervention.

METHODS

A 6-month pilot trial with 70 participants with a diagnosis of bipolar disorder, schizophrenia or schizoaffective disorder, and current active suicidal ideation were randomized to START or START with mobile augmentation. START consists of 4 weekly sessions addressing early warning signs and triggers, symptoms influencing suicidal thinking, and social relationships. Recovery planning is followed by biweekly telephone coaching. START with mobile augmentation includes personalized automated cognitive behavioral therapy scripts that build from in-person content. Participants were evaluated at baseline, 4 weeks (end of in-person sessions), 12 weeks (end of telephone coaching), and 24 weeks. In addition to providing point estimates of feasibility and acceptability, the primary outcome of the trial was the change in severity of suicidal ideation as measured with the Scale for Suicide Ideation (SSI) and secondary outcome included the rate of outpatient engagement.

RESULTS

The trial is ongoing. Feasibility and acceptability across conditions will be assessed using t tests or Mann-Whitney tests or chi-square tests. The reduction of SSI over time will be assessed using hierarchical linear models.

CONCLUSIONS

The design considerations and results of this trial may be informative for adapted suicide prevention in psychotic disorders in applied community settings.

Assessment of Suicide Risks During the First Week Immediately After Discharge From Psychiatric Inpatient Facility

Background: The suicide rate in first week after psychiatric discharge is alarmingly high. Although a risk assessment prior to discharge is standard praxis, it can be difficult to take into consideration the obstacles that patient will meet once discharged. A follow-up-visit during the first week after discharge is an opportunity to reevaluate whether a person may be at risk of suicide. Aim: To determine how many patients, of those who were assessed, were evaluated to be at elevated risk of suicide during the first week after psychiatric discharge and secondarily to identify predictors of this and predictors for receiving a follow-up visit during first week after discharge. Methods: All patients discharged between March 1st 2018 to January 17th 2019 were offered a home visit including a systematic risk assessment. Socio-demographics and clinical variables were obtained from medical records and logistic regression analyses were used to identify predictors of a higher suicide risk assessment as well as receiving a follow-up visit. Results: Information from 1905 discharges were included. Of these, 1,052 were seen in follow-up meetings. Risk assessments was conducted in a total of 567 discharge procedures, of which 28 (5%) had an elevated risk of suicide. A history of suicide attempt, suicide risk having been the reason for admission, a first diagnosis of a psychiatric disorder was associated with an elevated risk of suicide after discharge. Conclusion: Follow-up visits could serve as an important tool to identify people whose suicidal risk were overlooked at discharge or exposed to severe stressors after discharge.

Specialised early intervention teams (extended time) for recent-onset psychosis

BACKGROUND

Psychosis is an illness characterised by the presence of hallucinations and delusions that can cause distress or a marked change in an individual's behaviour (e.g. social withdrawal, flat or blunted effect). A first episode of psychosis (FEP) is the first time someone experiences these symptoms that can occur at any age, but the condition is most common in late adolescence and early adulthood. This review is concerned with FEP and the early stages of a psychosis, referred to throughout this review as 'recent-onset psychosis.' Specialised early intervention (SEI) teams are community mental health teams that specifically treat people who are experiencing, or have experienced, a recent-onset psychosis. SEI teams provide a range of treatments including medication, psychotherapy, psychoeducation, educational and employment support, augmented by assertive contact with the service user and small caseloads. Treatment is time limited, usually offered for two to three years, after which service users are either discharged to primary care or transferred to a standard adult community mental health team. Evidence suggests that once SEI treatment ends, improvements may not be sustained, bringing uncertainty about the optimal duration of SEI to ensure the best long-term outcomes. Extending SEI has been proposed as a way of providing continued intensive treatment and continuity of care, of usually up to five years, in order to a) sustain the positive initial outcomes of SEI; and b) improve the long-term trajectory of the illness.

OBJECTIVES

To compare extended SEI teams with treatment as usual (TAU) for people with recent-onset psychosis. To compare extended SEI teams with standard SEI teams followed by TAU (standard SEI + TAU) for people with recent-onset psychosis.

SEARCH METHODS

On 3 October 2018 and 22 October 2019, we searched Cochrane Schizophrenia's study-based register of trials, including registries of clinical trials.

SELECTION CRITERIA

We selected all randomised controlled trials (RCTs) comparing extended SEI with TAU for people with recent-onset psychosis and all RCTs comparing extended SEI with standard SEI + TAU for people with recent-onset psychosis. We entered trials meeting these criteria and reporting usable data as included studies.

DATA COLLECTION AND ANALYSIS

We independently inspected citations, selected studies, extracted data and appraised study quality. For binary outcomes we calculated the risk ratios (RRs) and their 95% confidence intervals (CIs). For continuous outcomes we calculated the mean difference (MD) and their 95% CIs, or if assessment measures differed for the same construct, we calculated the standardised mean difference (SMD) with 95% CIs. We assessed risk of bias for included studies and created a 'Summary of findings' table using the GRADE approach.

MAIN RESULTS

We included three RCTs, with a total 780 participants, aged 16 to 35 years. All participants met the criteria for schizophrenia spectrum disorders or affective psychoses. No trials compared extended SEI with TAU. All three trials randomly allocated people approximately two years into standard SEI to either extended SEI or standard SEI + TAU. The certainty of evidence for outcomes varied from low to very low. Our primary outcomes were recovery and disengagement from mental health services. No trials reported on recovery, and we used remission as a proxy. Three trials reported on remission, with the point estimate suggesting a 13% increase in remission in favour of extended SEI, but this included wide confidence intervals (CIs) and a very uncertain estimate of no benefit (RR 1.13, 95% CI 0.97 to 1.31; 3 trials, 780 participants; very low-certainty evidence). Two trials provided data on disengagement from services with evidence that extended SEI care may result in fewer disengagements from mental health treatment (15%) in comparison to standard SEI + TAU (34%) (RR 0.45, 95% CI 0.27 to 0.75; 2 trials, 380 participants; low-certainty evidence). There may be no evidence of a difference in rates of psychiatric hospital admission (RR 1.55, 95% CI 0.68 to 3.52; 1 trial, 160 participants; low-certainty evidence), or the number of days spent in a psychiatric hospital (MD -2.70, 95% CI -8.30 to 2.90; 1 trial, 400 participants; low-certainty evidence). One trial found uncertain evidence regarding lower global psychotic symptoms in extended SEI in comparison to standard SEI + TAU (MD -1.90, 95% CI -3.28 to -0.52; 1 trial, 156 participants; very low-certainty evidence). It was uncertain whether the use of extended SEI over standard SEI + TAU resulted in fewer deaths due to all-cause mortality, as so few deaths were recorded in trials (RR 0.38, 95% CI 0.09 to 1.64; 3 trials, 780 participants; low-certainty evidence). Very uncertain evidence suggests that using extended SEI instead of standard SEI + TAU may not improve global functioning (SMD 0.23, 95% CI -0.29 to 0.76; 2 trials, 560 participants; very low-certainty evidence). There was low risk of bias in all three trials for random sequence generation, allocation concealment and other biases. All three trials had high risk of bias for blinding of participants and personnel due to the nature of the intervention. For the risk of bias for blinding of outcome assessments and incomplete outcome data there was at least one trial with high or unclear risk of bias.

AUTHORS' CONCLUSIONS

There may be preliminary evidence of benefit from extending SEI team care for treating people experiencing psychosis, with fewer people disengaging from mental health services. Evidence regarding other outcomes was uncertain. The certainty of evidence for the measured outcomes was low or very low. Further, suitably powered studies that use a consistent approach to outcome selection are needed, but with only one further ongoing trial, there is unlikely to be any definitive conclusion for the effectiveness of extended SEI for at least the next few years.

Specialised early intervention teams for recent-onset psychosis

BACKGROUND

Psychosis is an illness characterised by the presence of hallucinations and delusions that can cause distress or a marked change in an individual's behaviour (e.g. social withdrawal, flat or blunted effect). A first episode of psychosis (FEP) is the first time someone experiences these symptoms that can occur at any age, but the condition is most common in late adolescence and early adulthood. This review is concerned with first episode psychosis (FEP) and the early stages of a psychosis, referred to throughout this review as 'recent-onset psychosis.' Specialised early intervention (SEI) teams are community mental health teams that specifically treat people who are experiencing, or have experienced a recent-onset psychosis. The purpose of SEI teams is to intensively treat people with psychosis early in the course of the illness with the goal of increasing the likelihood of recovery and reducing the need for longer-term mental health treatment. SEI teams provide a range of treatments including medication, psychotherapy, psychoeducation, and occupational, educational and employment support, augmented by assertive contact with the service user and small caseloads. Treatment is time limited, usually offered for two to three years, after which service users are either discharged to primary care or transferred to a standard adult community mental health team. A previous Cochrane Review of SEI found preliminary evidence that SEI may be superior to standard community mental health care (described as 'treatment as usual (TAU)' in this review) but these recommendations were based on data from only one trial. This review updates the evidence for the use of SEI services.

OBJECTIVES

To compare specialised early intervention (SEI) teams to treatment as usual (TAU) for people with recent-onset psychosis.

SEARCH METHODS

On 3 October 2018 and 22 October 2019, we searched Cochrane Schizophrenia's study-based register of trials, including registries of clinical trials.

SELECTION CRITERIA

We selected all randomised controlled trials (RCTs) comparing SEI with TAU for people with recent-onset psychosis. We entered trials meeting these criteria and reporting useable data as included studies.

DATA COLLECTION AND ANALYSIS

We independently inspected citations, selected studies, extracted data and appraised study quality. For binary outcomes we calculated the risk ratios (RRs) and their 95% confidence intervals (CIs). For continuous outcomes we calculated the mean difference (MD) and their 95% CIs, or if assessment measures differed for the same construct, we calculated the standardised mean difference (SMD) with 95% CIs. We assessed risk of bias for included studies and created a 'Summary of findings' table using the GRADE approach.

MAIN RESULTS

We included three RCTs and one cluster-RCT with a total of 1145 participants. The mean age in the trials was between 23.1 years (RAISE) and 26.6 years (OPUS). The included participants were 405 females (35.4%) and 740 males (64.6%). All trials took place in community mental healthcare settings. Two trials reported on recovery from psychosis at the end of treatment, with evidence that SEI team care may result in more participants in recovery than TAU at the end of treatment (73% versus 52%; RR 1.41, 95% CI 1.01 to 1.97; 2 studies, 194 participants; low-certainty evidence). Three trials provided data on disengagement from services at the end of treatment, with fewer participants probably being disengaged from mental health services in SEI (8%) in comparison to TAU (15%) (RR 0.50, 95% CI 0.31 to 0.79; 3 studies, 630 participants; moderate-certainty evidence). There was low-certainty evidence that SEI may result in fewer admissions to psychiatric hospital than TAU at the end of treatment (52% versus 57%; RR 0.91, 95% CI 0.82 to 1.00; 4 studies, 1145 participants) and low-certainty evidence that SEI may result in fewer psychiatric hospital days (MD -27.00 days, 95% CI -53.68 to -0.32; 1 study, 547 participants). Two trials reported on general psychotic symptoms at the end of treatment, with no evidence of a difference between SEI and TAU, although this evidence is very uncertain (SMD -0.41, 95% CI -4.58 to 3.75; 2 studies, 304 participants; very low-certainty evidence). A different pattern was observed in assessment of general functioning with an end of trial difference that may favour SEI (SMD 0.37, 95% CI 0.07 to 0.66; 2 studies, 467 participants; low-certainty evidence). It was uncertain whether the use of SEI resulted in fewer deaths due to all-cause mortality at end of treatment (RR 0.21, 95% CI 0.04 to 1.20; 3 studies, 741 participants; low-certainty evidence). There was low risk of bias for random sequence generation and allocation concealment in three of the four included trials; the remaining trial had unclear risk of bias. Due to the nature of the intervention, we considered all trials at high risk of bias for blinding of participants and personnel. Two trials had low risk of bias and two trials had high risk of bias for blinding of outcomes assessments. Three trials had low risk of bias for incomplete outcome data, while one trial had high risk of bias. Two trials had low risk of bias, one trial had high risk of bias, and one had unclear risk of bias for selective reporting.

AUTHORS' CONCLUSIONS

There is evidence that SEI may provide benefits to service users during treatment compared to TAU. These benefits probably include fewer disengagements from mental health services (moderate-certainty evidence), and may include small reductions in psychiatric hospitalisation (low-certainty evidence), and a small increase in global functioning (low-certainty evidence) and increased service satisfaction (moderate-certainty evidence). The evidence regarding the effect of SEI over TAU after treatment has ended is uncertain. Further evidence investigating the longer-term outcomes of SEI is needed. Furthermore, all the eligible trials included in this review were conducted in high-income countries, and it is unclear whether these findings would translate to low- and middle-income countries, where both the intervention and the comparison conditions may be different.

[Suicidal risk during the first psychotic episode]

Suicide is the most common cause of early mortality during the course of schizophrenia. The most recent data in the literature show that the risk of suicide is greater at the beginning of the course of schizophrenia. The risk of suicide during the first year is 12 times higher than that of the general population. Specifically, 2-5 % of people with first-episode psychosis will die by suicide in long-term follow-up studies. Regarding the presence of suicidal ideation that are a major factor of suicide in subjects suffering from psychotic disorders, their prevalence remains extremely worrying, since they are substantial and persistent. Consequently, suicide prevention should be a major and immediate objective in the management of the disease, as soon as the diagnosis has been made. Suicidal ideas are a potential precursor to the evolution towards acting out. Their evolution must be specifically assessed in each individual. Indeed, in the influential Danish OPUS study the authors reported heterogeneity in suicidal ideations in young patients with first episode of psychosis and identified three prototypical trajectories of suicidal ideations over the first 2 years in treatment. Particularly, nearly 40 % of patients with first-episode psychosis have persisting suicidal thoughts over the initial treatment period. Consequently, the authors recommend routine screening for suicidality when providing treatment for first-episode psychosis. The main risk factors for suicidal behavior in patients with a first episode are classical ones. Previous research has suggested that, in addition to young age and early course of illness, other important clinical predictors of suicide in individuals with schizophrenia include presence of depressive symptoms and misuse of substances, which are very common conditions in these patients. Lack of social support, loss, rejection, stigma, insight, fear of future losses, are all negative experiences experienced by patients starting a psychotic disorder. Negative connotations of the diagnosis of psychotic disorders, feelings of being trapped that can be directly related to feeling a burden can lead to suicidal crisis in these individuals. Then, the painful experience of the disease and its consequences associated with self-stigmatization and social rejection may induce hopelessness and suicidal thoughts in these young subjects. The quality of the insight and its evolution may worsen the depressive experience and suicidal risk and they therefore also require to be measured regularly. Thus, the clinical evaluation of patients entering psychosis should focus on those dimensions that are not directly related to the psychotic symptoms. At the precise evaluation of each patient must be associated personalized measures of prevention. It is now proposed that prevention strategies targeting suicidal behaviour in first-episode psychosis should not be universal. On a more general level, evidence-based data to support specific care programs are still lacking, and only few data are in favor of integrated care in patients presenting with first episode. It should also be kept in mind that the risk of suicide is extraordinarily high for all psychiatric patients during the first few months after discharge from hospital. This should encourage caregivers to offer intensive follow-up programs to their patients and to embrace recontact and follow-up initiatives using the tools of e-health. Last, programs for the early detection of schizophrenia seem to be beneficial for the prevention of suicide in these subjects.

Heterogeneity in Short-Term Suicidal Ideation Trajectories: Predictors of and Projections to Suicidal Behavior

OBJECTIVE

Little is known about suicidal ideation stability, including whether stability is heterogeneous or homogeneous between individuals. Studies of this kind are necessary to understand the progression from suicidal ideation to action.

METHOD

This study examined suicidal ideation trajectories, using growth mixture modeling, in a sample of 359 past/current military service members (M age = 32.1 years, SD = 7.7; 88.3% male). Self-reported suicidal ideation information was collected at baseline and follow-up sessions at months 1, 3, 6, and 12. Following extraction of the best-fitting solution, predictors of trajectory status were examined and trajectory status was used to predict suicidal behavior between baseline and month 12 assessments.

RESULTS

Results revealed four trajectories, Low-Stable (n = 125), Moderate-Stable (n = 101), High-Stable (n = 76), and High-Rapidly Declining (n = 57). In general, the High-Stable trajectory had the highest levels of perceived burdensomeness, thwarted belongingness, PTSD symptoms, and drug use. The High- and Moderate-Stable trajectories had the highest rates of suicidal behavior between baseline and month 12.

CONCLUSIONS

Suicidal ideation, even in individuals with elevated ideation, is not a homogeneous construct over time. Stability of suicidal ideation might be an important risk factor, even if ideation is only moderately elevated.

Consistency of trajectories of suicidal ideation and depression symptoms: Evidence from a randomized controlled trial

BACKGROUND

Depression is a risk factor for suicidal ideation. However, suicidal ideation can occur in the absence of depression and treating depression may not reduce suicidal thinking. This study tested whether trajectories of suicidal thinking are concordant with trajectories of depressive symptoms and sought to identify factors associated with these trajectories.

METHODS

Participants were community-based Australian adults (N = 418, 77% female) enrolled in a randomized controlled trial evaluating the effectiveness of an online cognitive-behavioral intervention for suicidal ideation. Separate linear growth mixture models were estimated across 12 months of follow-up to identify longitudinal trajectories of suicidal ideation and depression symptoms. Predictors of latent class membership were tested using logistic regression models.

RESULTS

Two-class models were found to have optimal fit for both suicidal thinking and depressive symptoms. Trajectory classes of suicidal ideation were: (1) moderate severity decreasing over time; and (2) high severity remaining stable over time. Depression trajectories were: (1) moderate severity with a small decrease over time; and (2) high severity that decreased moderately over time. Lower perceived burdensomeness was associated with having a greater decrease in both suicidal thinking and depression. More severe mental health symptoms were associated with less decrease in depression symptoms but not with suicidal ideation trajectory.

CONCLUSION

Class membership across the two outcomes and predictors of class membership were found to be largely independent. The lack of coupling in trajectories and predictors suggests that changes in suicidal thinking may occur independently of changes in depression.

The dynamic relationship between insight and suicidal behavior in first episode psychosis patients over 3-year follow-up

Studies have established the high risk of suicide in first episode psychosis (FEP). Between 15% and 26% of FEP patients attempt suicide at least once before their first contact with psychiatric services and 2-5% die from suicide. Also, many patients with schizophrenia spectrum disorders lack insight into having a mental disorder. However, the relationship between insight changes and suicidal behavior in FEP remains poorly understood. In the present study information about suicidal behavior over a 3 years period was available on a cohort of 397 FEP patients, of whom 270 were assessed in the three dimensions of insight (into mental illness, the need for treatment, and the social consequences) at baseline, 1 and 3 years after treatment initiation. Survival analyses examined time to suicidal behavior in relation to (i) insight at baseline, (ii) the closest insight measure to the suicide attempt, and (iii) changes in insight during the follow-up. No associations were found between baseline insight dimensions and time to suicidal behavior. However, poor insight at the evaluation closest to the suicide attempt was associated with an increased risk of suicide. Stability of insight did not affect the risk of suicidal behavior, while changes in either direction were linked with an increased risk of suicidal behavior, particularly worsening insight. Insight in psychosis is a dynamic concept and we demonstrated the relationship between insight and suicide risk to be equally dynamic. Poor insight seems to increase the risk, especially when insight levels change. Repeated insight assessment to detect change from early psychosis may play a role in suicide prevention.

Eradicating Suicide at Its Roots: Preclinical Bases and Clinical Evidence of the Efficacy of Ketamine in the Treatment of Suicidal Behaviors

Despite the continuous advancement in neurosciences as well as in the knowledge of human behaviors pathophysiology, currently suicide represents a puzzling challenge. The World Health Organization (WHO) has established that one million people die by suicide every year, with the impressive daily rate of a suicide every 40 s. The weightiest concern about suicidal behavior is how difficult it is for healthcare professionals to predict. However, recent evidence in genomic studies has pointed out the essential role that genetics could play in influencing person's suicide risk. Combining genomic and clinical risk assessment approaches, some studies have identified a number of biomarkers for suicidal ideation, which are involved in neural connectivity, neural activity, mood, as well as in immune and inflammatory response, such as the mammalian target of rapamycin (mTOR) signaling. This interesting discovery provides the neurobiological bases for the use of drugs that impact these specific signaling pathways in the treatment of suicidality, such as ketamine. Ketamine, an N-methyl-d-aspartate glutamate (NMDA) antagonist agent, has recently hit the headlines because of its rapid antidepressant and concurrent anti-suicidal action. Here we review the preclinical and clinical evidence that lay the foundations of the efficacy of ketamine in the treatment of suicidal ideation in mood disorders, thereby also approaching the essential question of the understanding of neurobiological processes of suicide and the potential therapeutics.

Trajectories of depressive symptoms in the acute phase of psychosis: Implications for treatment

Depression is common in schizophrenia and associated with negative outcomes. Previous studies have identified heterogeneity in treatment response in schizophrenia. We aimed to investigate different trajectories of depression in patients suffering from psychosis and predictors of change in depressive symptoms during antipsychotic treatment. Two hundred and twenty-six patients >18 years acutely admitted due to psychosis were consecutively included and the follow-up was 27 weeks. The Calgary Depression Scale for Schizophrenia (CDSS) sum score was the primary outcome. Latent growth curve (LGCM) and Growth Mixture Models (GMM) were conducted. Predictors were the Positive sum score of the Positive and Negative Syndrome Scale for Schizophrenia (PANSS), Schizophrenia spectrum/non-spectrum psychoses, gender and being antipsychotic naive at inclusion. We found support for three depression-trajectories, including a high- (14.7%), a low depression-level (69.6%) class and a third depressed class quickly decreasing to a low level (15.7%). Change in CDSS was associated with change in PANSS positive score in all time intervals (4 weeks: b = 0.18, p < 0.001, 3 months: 0.21, p < 0.023, 6 months: 0.43, p < 0.001) and with a diagnosis within schizophrenia spectrum but not with antipsychotic naivety or gender. The schizophrenia-spectrum patients had less depressive symptoms at inclusion (-2.63, p < 0.001). In conclusion, an early responding and a treatment refractory group were identified. The treatment-refractory patients are candidates for enhanced anti-depressive treatment, for which current evidence is limited. The post-psychotic depression group was characterized by depressive symptoms in the acute phase as well. We could not identify differentiating characteristics of the depression trajectories.

Depression during first episode psychosis and subsequent suicide risk: A systematic review and meta-analysis of longitudinal studies

BACKGROUND

Evidence suggests first episode psychosis (FEP) is associated with suicide, and the influence of depression on suicidal behaviour in cross sectional studies is clear. However the influence of depression during FEP on longer-term mortality is not certain. Existing evidence was synthesised to understand the influence of depressive symptoms during FEP on subsequent suicidal behaviour.

METHODS

Medline, Embase, PsycINFO, Cochrane Library, Web of Science, OpenGrey, and NICE Evidence were searched from inception to Jan 25, 2017. Longitudinal observational studies assessing the relationship between depressive symptoms during FEP with a measure of s at a specified follow-up time were included. Summary estimates were extracted. The Downs and Black Instrument was used to appraise study quality. Odds ratio (OR) of suicidal behaviour were calculated using random effects meta-analyses. The study protocol was registered with PROSPERO (CRD42017055881).

RESULTS

Of 4210 articles found, 23 fulfilled eligibility criteria. 13 were included in meta-analysis (n=3002). 428 participants demonstrated suicidal behaviour in the study periods. Odds of suicidal behaviour during follow-up were significantly higher among patients with depressive symptoms during FEP compared to those without (OR=1.59, 95% CI 1.14-2.21; I2=50.0%, p=0.02). Meta-regression demonstrated no evidence of influence of length of follow-up on results.

CONCLUSIONS

Depressive symptoms during FEP are associated with increased longer-term risk of suicidal behaviour. This association should be acknowledged during early management planning. Large-scale clinical trials are needed to identify efficacious management of depression during FEP.

Trajectories of suicidal ideation over 6 months among 482 outpatients with bipolar disorder

INTRODUCTION

Suicidal ideation occurs frequently among individuals with bipolar disorder; however, its course and persistence over time remains unclear. We aimed to investigate 6-months trajectories of suicidal ideation among adults with bipolar disorder.

METHODS

The Bipolar CHOICE study randomized 482 outpatients with bipolar disorder to 6 months of lithium- or quetiapine-based treatment including other psychotropic medications as clinically indicated. Participants were asked at 9 visits about suicidal ideation using the Concise Health Risk Tracking scale. We performed latent Growth Mixture Modelling analysis to empirically identify trajectories of suicidal ideation. Multinomial logistic regression analyses were applied to estimate associations between trajectories and potential predictors.

RESULTS

We identified four distinct trajectories. The Moderate-Stable group represented 11.1% and was characterized by constant suicidal ideation. The Moderate-Unstable group included 2.9% with persistent thoughts about suicide with a more fluctuating course. The third (Persistent-low, 20.8%) and fourth group (Persistent-very-low, 65.1%) were characterized by low levels of suicidal ideation. Higher depression scores and previous suicide attempts (non-significant trend) predicted membership of the Moderate-Stable group, whereas randomized treatment did not.

LIMITATIONS

No specific treatments against suicidal ideation were included and suicidal thoughts may persist for several years.

CONCLUSION

More than one in ten adult outpatients with bipolar disorder had moderately increased suicidal ideation throughout 6 months of pharmacotherapy. The identified predictors may help clinicians to identify those with additional need for treatment against suicidal thoughts and future studies need to investigate whether targeted treatment (pharmacological and non-pharmacological) may improve the course of persistent suicidal ideation.

Self-harm and suicide attempts in Schizophrenia

BACKGROUND

The risk of suicide among persons with schizophrenia (SZ) is higher than in general population, with multiple contributory factors. We assessed the prevalence of risk of deliberate self-harm and suicide attempts, along with associated socio-demographic and clinical factors in a group of SZ outpatients (n=61) as part of a larger study on overall schizophrenia-associated risks.

AIMS

To investigate factors associated with risk of deliberate self-harm and suicide among persons with schizophrenia.

METHOD

Out of 270 SZ participants evaluated for various risks using Ram Manohar Lohia Risk Assessment Interview (RML-RAI), 61 reported risk of self-harm including suicide attempt/s. The factors associated with this risk were further evaluated on clinical details and Diagnostic Interview for Genetic Studies.

RESULTS

Risk of reported self-harm was 22.59%. Among them, 10% had attempted suicide at least once. Current age and past month Global Assessment of Functioning score from DIGS (GAF) were significantly correlated with suicide attempt. Attempters had significantly lower current GAF score, indicating poorer functioning. Among 27 attempters, 9 attempted at the onset of illness while 6 others attempted suicide within one year. Most common method of attempt was ingestion of insecticides or overdose of medication, followed by hanging or jumping from height.

CONCLUSION

In our hospital-based sample of suicide attempters, 10% had attempted suicide, among them over 55% within first year of illness. Attempters were significantly older than non-attempters and suffered from significantly more severe illness than non-attempters. Positive symptoms were significantly associated with attempt, irrespective of time at which suicide was attempted.

Suicidal Ideation in an Egyptian Sample of Hospitalized Patients with Acute Psychosis

BACKGROUND

Suicide mortality is 12 times higher in psychotic patients compared to the general population. Identifying characteristic of suicidal patients among this group might help in preventing such behavior.

AIMS

To assess the predictors of suicidal risk in patients hospitalized due to acute psychosis.

METHODS

One hundred and fifty patients (age 18 - 60 years) admitted with acute psychotic features were recruited. Patients were evaluated clinically by The Arabic version of Mini International Neuropsychiatric Interview (M.I.N.I.). Suicidal ideation was assessed using the Scale for Suicide Ideation (SSI).

RESULTS

Forty four out of 150 patients (29.33%) reported having current and/or previous history of suicidal ideation. Patients with major depression showed the highest suicidal tendencies followed by delusional disorder then bipolar disorder, psychosis related to substance abuse and schizophrenia. The more severe the psychotic symptoms, the more suicidal tendencies shown by patients. Predictors for suicidal ideations included diagnostic category, severity of psychotic features, unemployement and younger age CONCLUSION: Patients with psychosis that require admission to the hospital carry a high risk of suicidal ideation and behavior. Factors like unemployment, young age and psychiatric diagnosis and severity of psychosis could be predicting factors.

Trajectories of Suicidal Ideation in People Seeking Web-Based Help for Suicidality: Secondary Analysis of a Dutch Randomized Controlled Trial

BACKGROUND

Suicidal ideation (SI) is a common mental health problem. Variability in intensity of SI over time has been linked to suicidal behavior, yet little is known about the temporal course of SI.

OBJECTIVE

The primary aim was to identify prototypical trajectories of SI in the general population and, secondarily, to examine whether receiving Web-based self-help for SI, psychiatric symptoms, or sociodemographics predicted membership in the identified SI trajectories.

METHODS

We enrolled 236 people, from the general Dutch population seeking Web-based help for SI, in a randomized controlled trial comparing a Web-based self-help for SI group with a control group. We assessed participants at inclusion and at 2, 4, and 6 weeks. The Beck Scale for Suicide Ideation was applied at all assessments and was included in latent growth mixture modeling analysis to empirically identify trajectories.

RESULTS

We identified 4 SI trajectories. The high stable trajectory represented 51.7% (122/236) of participants and was characterized by constant high level of SI. The high decreasing trajectory (50/236, 21.2%) consisted of people with a high baseline SI score followed by a gradual decrease to a very low score. The third trajectory, high increasing (12/236, 5.1%), also had high initial SI score, followed by an increase to the highest level of SI at 6 weeks. The fourth trajectory, low stable (52/236, 22.0%) had a constant low level of SI. Previous attempted suicide and having received Web-based self-help for SI predicted membership in the high decreasing trajectory.

CONCLUSIONS

Many adults experience high persisting levels of SI, though results encouragingly indicate that receiving Web-based self-help for SI increased membership in a decreasing trajectory of SI.
