Comparative Effectiveness of Ultra-Brief, IPT-A Based Crisis Intervention for Suicidal Children and Adolescents.

BACKGROUND: In recent years, suicidal thoughts and behaviors have become increasingly common among children and adolescents, leading to an elevation in the number of visits to emergency departments in pediatric hospitals. In Israel, the rising demand for mental health treatment due to suicidal distress is also salient, creating prolonged wait periods and low case acceptance rates. Addressing the urgent need for streamlined interventions, the present study outlines the design and results of a non-inferiority effectiveness trial of an ultra-brief suicide crisis intervention based on Interpersonal Psychotherapy for Adolescents (IPT-A-SCI). METHODS: 309 children and adolescents presenting to the Depression and Suicide Clinic at Schneider Children's Medical Center of Israel with depressive and anxiety symptoms and/or suicidal ideation/behavior were assigned to either IPT-A-SCI, Treatment as Usual (TAU), or waitlist condition. Assessments were conducted pre- and post-intervention/after five sessions/five weeks (as secondary assessments) in accordance with group assignment. RESULTS: At secondary assessment, post IPT-A-SCI, suicide ideation, and behavior as well as depression and anxiety symptoms significantly decreased, with no group differences observed between IPT-A-SCI, TAU, and control groups. CONCLUSION: IPT-A-SCI is feasible and as effective as the standard treatment in reducing suicidal, depressive, and anxiety symptoms among children and adolescents.

Risk and protective factors for substance use and media addictive behaviors in adolescents during the COVID-19 pandemic.

OBJECTIVE: This study examined the long-term effects of the COVID-19 pandemic on adolescents' substance use, digital media use, and symptoms of internet, gaming, and social media addiction. METHOD: A nationally representative longitudinal cohort of 1665 Israeli teens and preteens, aged 9-16, completed questionnaires assessing substance use prevalence, daily screen time, symptoms of media addiction, and potential risk and protective factors. Data were collected before the pandemic (October 2019), after the second wave lockdown (November 2020), and after the fifth wave (April 2022) in Israel. RESULTS: The analysis documented significant increases in substance use, daily screen time, and social media addiction indices over time. Gratitude, life satisfaction, positive emotions, future orientation, grit, and secure attachment emerged as significant protective factors. Sensation-seeking, negative emotions, and mental health symptoms were identified as risk factors. CONCLUSIONS: These findings highlight the importance of educational and public mental health services in addressing the pandemic's long-term impact on the mental health and addictive behaviors of adolescents. They also emphasize the significance of enhancing protective factors and reducing risk factors to effectively mitigate substance and digital media abuse among adolescents.

When a Patient Dies From Suicide: A Survey Among Mental Health Professionals in Israel.

Death of patients by suicide can have powerful impacts on mental health professionals (MHPs). The National Program for the Prevention of Suicidality and Suicide at Israel's Ministry of Health decided to invest in MHPs who have lost patients by suicide. Two hundred and two MHPs completed an online self-report survey regarding their emotional response, professional identity, and clinical practice, and the aid they felt would be supportive following a patient's suicide. Results indicated that 35% of MHP experienced at least one death of a patient by suicide. Respondents experienced difficult emotional reactions, and many felt responsible for the suicide. Nearly 50% reported that the patient's suicide affected their clinical practice. Most respondents reported the need for a support framework and information about the processes following a patient's suicide. It is important to increase awareness of the possibility of losing a patient by suicide and offer an appropriate supportive framework.

Implicit Identification with Death, Clinician Evaluation and Suicide Ideation among Adolescent Psychiatric Outpatients-The Mediating Role of Depression.

Implicit identification with death (i.e., subconsciously self-associating oneself with death), measured by the Death-Suicide Implicit Association Test (D/S-IAT), is associated with Suicide Ideation (SI). Our understanding of the mechanisms underlying this association is limited. The current study examined (1) the mediating role of depression between D/S-IAT and recent SI and (2) the association between SI, D/S-IAT, and clinician evaluation of SI among a clinical sample of adolescents. 148 adolescents aged 10-18 years (69.4% female) from two outpatient clinics were assessed at intake. Participants completed D/S-IAT and self-report measures for recent SI and depression during intake. Findings indicate that depression is a mediator between D/S-IAT and recent SI, controlling for gender, site differences, and past suicidal thoughts and behaviors. D/S-IAT and clinician evaluation were correlated with recent SI but not beyond depression. Our findings highlight the importance of examining the underlying psychological mechanisms regarding the association between D/S-IAT and suicide.

Burnout, depression, and suicidal ideation among physicians before and during COVID-19 and the contribution of perfectionism to physicians' suicidal risk.

Objectives: There is limited data regarding the prevalence of suicidal risk among physicians during COVID-19, and the risk factors relating to it. Dominant risk factors for suicide among physicians are depression and burnout. Maladaptive perfectionism may also serve as a profound risk factor for suicidality among physicians and may aggravate symptoms of distress under the challenges of COVID-19. This study aims to evaluate current suicidal risk, suicidal ideation, depression, and burnout before and during COVID-19 among physicians in Israel, and to identify the best sets of correlates between perfectionism and burnout, depression and suicidal ideation, during these time periods. Methods: A sample of 246 Israeli physicians (160 before COVID-19 and 86 during COVID-19) completed online surveys assessing lifetime suicidal risk, suicidal ideation during the last year and current suicidal ideation, depression, burnout symptoms and maladaptive perfectionism. Results: More than one-fifth of the sample (21.9%) reported high suicidal risk (Lifetime suicidal behaviors). More than one-fourth (27.2%) reported suicidal ideation during the last 12 months; and 13.4% reported suicidal ideation during the last 3 months. In addition, more than one-third (34.6%) exhibited moderate-severe levels of depressive symptoms and more than a half of the sample reported burnout symptoms. Maladaptive perfectionism was positively correlated with current suicidal ideation, burnout, and depression. Moderated serial mediation analysis demonstrated indirect effect of perfectionism on suicidal ideation by its impact on burnout and depression only during COVID-19. Before COVID-19, physicians were more likely to experience depressive symptoms. Conclusion: Physicians in Israel are at increased risk for depression and suicidal ideation, regardless of the COVID-19 pandemic. Maladaptive perfectionism was found to be a risk factor for burnout, depression, and suicidal ideation. During the first waves of the pandemic, physicians were less likely to experience depressive symptoms. However, among physicians who were characterized with high maladaptive perfectionism, depression served as a significant risk factor for suicidal ideation during the pandemic, which places these individuals at increased risk for suicidality. These results highlight the importance of implementing intervention programs among physicians to reduce suicidal risk and to better identify rigid perfectionism and depressive symptoms.

The "Forgotten Grievers": The Impact of Pupil Suicide on Post-Trauma and Grief Symptoms in School Staff.

BACKGROUND: The suicide of a pupil impacts survivors greatly, but most studies on the subject do not consider school staff, and do not differentiate between the various professional domains. Our aim was to investigate the existence of differences in symptoms of complicated grief as well as post-trauma symptoms after a pupil's suicide, among school staff in four domains: counsellors, psychologists, principals and home-room teachers. METHOD: Eighty-four staff members from schools that lost pupils to suicide within the past five years were assessed for symptoms of complicated grief and trauma. All reported their symptoms using self-report scales. RESULTS: Principals and home-room teachers had significantly higher complicated grief and post-trauma symptoms. The main limitations of this study are that the data were collected via self-report questionnaires, which can introduce bias. Additionally, the sample is relatively small and comprises mainly women. CONCLUSIONS: School professionals in domains receiving less coping and crisis training, and those with supervisory responsibilities (principals and home-room teachers) show more symptoms of trauma and complicated grief after a pupil's suicide, and require special attention. More preparatory training would surely benefit them and assist them in coping with such crises.

Suicidal ideation and behavior among perinatal women and their association with sleep disturbances, medical conditions, and known risk factors.

Objective: Suicide is considered one of the leading causes of maternal mortality, especially among women with postpartum depression. In the current systematic review, we conducted a qualitative data synthesis of recent studies exploring novel risk factors including sleep disturbances and medical conditions, alongside known and significant risk factors for perinatal suicidality. Evidence acquisition: We conducted a systematic search of the literature according to PRISMA guidelines on PubMed, PsycNET, and Scopus databases. Search terms were "pregnancy" "OR" "postpartum" "OR" "peripartum" "OR" "perinatal" "OR" "postnatal" combined with the Boolean "AND" operator with "suicide" "OR" "suicidality" "OR" "suicidal ideation" "OR" "suicidal behavior." Evidence synthesis: The initial search yielded 1,458 records, of which 51 research reports that met inclusion criteria were analyzed. These 51 studies sampled a total of 45,942 participants. Clinically, sleep disturbance, psychopathology, and social support have been identified as dominant risk factors for suicidal behavior among pregnant and postpartum women, as well as medical conditions and aversive life events. Conclusion: Monitoring sleep disturbance, depression, and perceived social support is critical given that they are significant risk factors for suicide among perinatal women. Early identification of perinatal women who may be at risk of suicide, although not depressed, is crucial. Limitations: The use of tools designed to identify depression to identify suicidal risk, fail to identify women who are at risk but who do not suffer from depression. Other methodological limitations are the lack of longitudinal studies and the complexity of examining suicidal behavior in sample studies.

The Serious Suicide Attempts Approach for Understanding Suicide: Review of the Psychological Evidence.

The study of survivors of a serious suicide attempt (SSA)--an attempt that would have been fatal had it not been for the provision of rapid and effective emergency treatment--can help researchers understand the suicidal mind. Serious suicide attempters are epidemiologically very similar to those who died by suicide, and thus can serve as valid proxies for studying suicides. In this paper, our objective was to briefly review the main risk factors that may facilitate more dangerous suicide behavior with high levels of intent. Our review highlights several dimensions of risk factors for SSAs, including psychopathology, mental pain, communication difficulties, decision-making impulsivity, and aggression. Several studies have indicated that the interaction between some of these dimensions, especially between mental pain and interpersonal difficulties, may serve as major catalysts for SSAs. Suicidal risk assessment should incorporate a designated evaluation of these risk factors as part of suicide prevention models.

Emotion perception and theory of mind in adolescents with major depression.

BACKGROUND: The research of theory of mind (ToM) and emotion perception (EP) in adolescents with major depressive disorder (MDD) is scarce, and no study to date has investigated the association between EP and long-term outcomes of adolescents with MDD. The aim of the current study was to evaluate ToM and EP in adolescents with MDD, as compared to healthy controls (HCs). In addition, we aimed to assess the association between impairment in ToM and EP, depressive symptom severity, and long-term outcome in the MDD group. METHODS: We compared the performance of 14 adolescents with MDD and 25 HC in the Facial Expression Recognition Task (FERT) and the Interpersonal Perception Task. We followed up with the MDD group 2 years later to assess the level of their depressive symptoms using the Children's Depression Rating Scale-Revised (CDRS-R). RESULTS: No differences were found between adolescents with MDD and HC in the ToM and FERT tasks. Also, within the MDD group, there was no association between the severity of depressive symptoms and task performance. In the MDD group, there was a significant correlation between lower levels of accuracy in the FERT during the index depressive episode and lower CDRS-R scores on follow-up 2 years later (r2 = 0.35, p = 0.021). CONCLUSIONS: EP impairments in adolescents with MDD might predict worse long-term outcome. Further research is needed to verify our findings and to assess for a possible neurobiological underpinning for the state and trait impairments in EP in adolescents with MDD.

Siblings of Individuals With Eating Disorders: A Review of the Literature.

Eating disorders (EDs) are serious psychopathologies characterized by a persistent disturbance in eating or eating-related behavior. Studies have shown EDs' detrimental consequences not only for patients, but also for their families. Nevertheless, a specific group that has so far been neglected, in both the research and clinical fields, are siblings of individuals with EDs. In an effort to identify this population's needs, and to facilitate effective prevention and treatment, this paper aims to review the existing literature on the subject, and examine siblings' personal experience, ways of coping, and levels of psychopathology. PubMed and PsycNet databases were searched with no publication date restrictions, yielding 26 relevant papers. Studies were categorized according to common themes they addressed, and subsequently summarized by highlighting common features, as well as information unique to each study. Several themes emerged, including emotional well-being, psychopathology, social consequences, family dynamics, and coping strategies. Results show that EDs experienced by one individual have significant effects on one's siblings, such as a decrease in quality of life, social isolation, and elevated familial strain. In several studies siblings were found to have elevated levels of psychopathology and EDs related symptoms. Nevertheless, findings' nature and magnitude were highly varied. The review indicates the need for further studies that will examine possible intra- and interpersonal moderating factors for EDs' impact on well-being among siblings, and take into consideration the substantial heterogeneity in studies conducted thus far. Additionally, this review highlights the need for novel and effective interventions, specifically targeting this at-risk group.

"Will you treat me? I'm suicidal!" The effect of patient gender, suicidal severity, and therapist characteristics on the therapist's likelihood to treat a hypothetical suicidal patient.

The purpose of our study was to broaden the understanding regarding mental health professionals' willingness to treat and likeliness to refer suicidal patients to other professionals. More specifically, our aim was to examine the effect of the patient's gender and suicidal severity, as well as the mental health professionals' personal and professional characteristics, on the willingness to treat and likeliness to refer. A total of 331 mental health professionals were randomly exposed to one of four case descriptions of a hypothetical patient in a crisis. The cases shared a common background story; however, they differed in terms of the patient's gender and suicidal condition (high vs. low). The exposure was followed by questionnaires aimed to reflect the subject's evaluation of the patient's suicidal severity, the subject's sense of competence and responsibility, willingness to treat or likeliness to refer, emotional contagion, and depression. The results indicate a lower willingness to treat and higher likelihood to refer suicidal patients compared with depressed patients. In addition, subjects exposed to the high suicidality cases showed a greater willingness to treat and refer female patients compared with male patients. A sense of competence was found as the strongest predictor of mental health professionals' willingness to treat and likelihood to refer, and emotional contagion was found as a predictor of likelihood to refer. It is important that mental health professionals be aware of the low tendency to treat suicidal patients especially if they are male. Further research should explore suitable training programmes and their application in the mental health curriculum.

A multi factorial model of self-harm behaviors in Anorexia-nervosa and Bulimia-nervosa.

BACKGROUND: Co-existence of eating disorders and NSSI, suicide attempts and ideations is well established yet much is not known about the personality traits and behavioral tendencies that maintain this relationship. To this date no empirical work has been produced that offers a multifactorial view on the contributing variables to the occurrence of self-harm behaviors in EDs. METHOD: Binge eating, depression, impulsivity, ruminations and loss aversion were assessed in a sample of 93 patients diagnosed with Anorexia-Nervosa and Bulimia-Nervosa and other EDs with a history of NSSI and suicide attempts. RESULTS: Binge eating was found to be a predictor of depression, which in turn was found to be related to NSSI frequency, suicide attempts and suicide ideations. Ruminations were found to mediate a relationship between depression and suicide ideations. Trait impulsivity predicted suicide attempts, while the attentional construct of impulsivity was associated to suicide ideations as well as attempts. Higher loss aversion was positively associated with NSSI frequency and suicide ideations. CONCLUSION: Our findings suggest that trait and state aspects of impulsivity are related to different self-harm behaviors in EDs. Exploring these differences is potentially of great value in understanding the process of transition from suicidal ideation to suicide attempt and the process of NSSI and may assist clinicians formulate better interventions for patients with EDs at risk. Ways in which individual findings in our model correspond with previous research and future implications are discussed.

The Fear of Losing-Nonsuicidal Self-Injury as a Protective Mechanism in Eating Disorders.

Background: This study examined the moderating role of loss aversion (LA) on the relationship between impulsivity, nonsuicidal self-injury (NSSI), suicidal attempts, and ideations among Eating Disorder (ED) patients. Methods: Data was collected on 81 ED patients and 37 healthy controls. ED patients were divided into 2 groups: 25 AN-Rs, 56 AN-BPs and BNs. Measurements of trait impulsivity, LA, NSSI, suicide attempts, and suicide ideations were collected. Results: The rate of attempting suicide was highest in the AN-BP/BN (34.8%), lower in the AN-Rs (8%), and the lowest in the controls (2.7%). Suicide ideation was also higher in AN-BP/BN compared to both AN-R and controls. NSSI was higher in the AN-BP/BN group compared to both AN-R and control groups. LA scores were lower among participants with EDs compared to controls. BMI and depression were positively associated with suicide ideation and NSSI. Impulsivity was associated to suicide attempt and suicide ideation. Contrary to our hypothesis, LA scores were positively correlated with NSSI and SI. A stepwise regression revealed that contradictory to our hypothesis, higher LA predicted NSSI prevalence severity of NSSI and suicide ideation. Limitations: (1) Cross-sectional design; (2) Relatively small sample size of clinical subjects and only female participants; (3) Heterogeneity of treatment status. Conclusions: EDs are associated with lower levels of LA compared to general population. Although high LA is considered a protective factor against "high damage" decisions, it may serve as a facilitator of lower risk decisions which help the individual soothe and communicate his or her own suffering such as NSSI.

Socio-demographic and psychological risk factors for suicidal behavior among individuals with anorexia and bulimia nervosa: A systematic review.

OBJECTIVE: Suicide is the second leading cause of death among individuals with anorexia nervosa (AN) and is also elevated in bulimia nervosa (BN). We carried out a systematic review in which we analyzed the relationship between AN and/or BN and suicidality (i.e. suicidal ideation or attempted and/or death by suicide) and the major risk factors for suicidal behavior among AN and BN patients by synthesizing the qualitative data from relevant studies. EVIDENCE ACQUISITION: According to PRISMA guidelines, we conducted a systematic search of the literature on PsycNET, PubMed, Google Scholar, and ScienceDirect. Search terms were "eating disorders" "OR" "anorexia" "OR" "bulimia" combined with the Boolean "AND" operator with "suicide." EVIDENCE SYNTHESIS: The initial search identified 8,590 records, of which 38 research reports met the predefined inclusion criteria and were analyzed. Eating disorders (EDs) were found to be associated with a marked increase in suicidal behaviors and ideation. ED type, impulsivity, and specific interpersonal features were associated with suicidal behavior. CONCLUSIONS: Our findings highlight the importance of the combined role of socio-demographic and psychological factors to the co-occurrence of EDs and suicidal behavior. It is imperative that a thorough suicide assessment be conducted routinely for individuals with past and current EDs, and that clinicians be aware that this risk may be ongoing and occur throughout treatment, even after ED symptoms appear to be remitting. LIMITATIONS: Study limitations include diagnostic definitions of and criteria for EDs, and the different terminology used by researchers to define suicide, including non-suicidal behaviors, which weakens the ability to draw conclusions regarding actual suicidal behaviors versus other self-harm behaviors.

Aggression, impulsivity, and their predictive value on medical lethality of suicide attempts: A follow-up study on hospitalized patients.

BACKGROUND: This study examined the role of aggressive-impulsive variants, and suicide history in predicting the medical severity of follow-up suicide attempts. METHODS: 97 consecutive psychiatric in-patients who participated in earlier study 2-5 years previously. Thirty-three had a history of a medically serious suicide attempt (MSSA), 29 had a history of a medically non-serious suicide attempt (MNSSA), and 35 had no history of suicide. Participants completed a battery of instruments measuring aggressive-impulsive variables, hopelessness and communication difficulties. Findings were analyzed in relation to follow-up suicide attempts and their severity. RESULTS: 32 patients (33%) had attempted suicide: 9 (9.27%) (including one death) MSSSA. Of these, 7 patients were MSSAs in the index attempt and 2 were MNSSAs in the index attempt. 23 (23.7%) MNSSA: Of these, 6 were MSSAs in the index attempt; 13, MNSSAs in the index attempt and 4 from the non-suicidal psychiatric group. 65 patients (67%) did not attempt suicide during the period since the index studies. Anger-out, violence impulsivity and hopelessness had significant positive correlations with medical severity of follow-up suicide attempts. Similar correlations were found between anger-out, violence and the amount of follow-up suicide attempts. A hierarchical regression analysis was conducted to determine contribution of study variables to severity of future suicide attempts. Severity of index attempt, hopelessness aggressive-impulsive variants and two interactions (medical severity of index suicide attempt X impulsivity and self-disclosure X anger-in) accounted for 44.7% of the variance of the medical severity of follow-up suicide attempts. LIMITATIONS: (i) Possibly incomplete patient information, as some of the patients who participated in the index studies could not be located. (ii) Relatively small group of patients with an index MSSA. CONCLUSIONS: The major findings of this paper are the predictive value of MSSA vs. MNSSA. The Lethality of future suicide attempt is closely linked to the lethality of former suicide attempt, impulsivity and hopelessness. Thus, patients who have made a suicide attempt should be assessed for medical severity of the attempt, impulsive-aggressive measures hopelessness, and communication difficulties, which are important factors in follow-up attempts.

Serious Suicide Attempts: Systematic Review of Psychological Risk Factors.

BACKGROUND: One of the main obstacles in studying suicide risk factors is the difference between cases in which the individual died by suicide and those in which the individual engaged in suicidal behavior. A promising strategy that overcomes this obstacle is the study of survivors of serious suicide attempt (SSA), i.e., an attempt that would have been lethal had it not been for the provision of rapid and effective emergency treatment. Serious suicide attempters are epidemiologically very much like those who died by suicide, and thus may serve as valid proxies for studying suicides. This paper aims to define the specific risk factors for SSAs by conducting a qualitative data synthesis of existing studies. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we conducted a systematic search of the literature in PubMed, ProQuest, and Psychlit electronic research-literature databases. Search terms were "serious" "OR" "near lethal," combined with the Boolean "AND" operator with "suicide*." In addition, we performed a manual search on Google Scholar for further studies not yet identified. RESULTS: The preliminary search identified 683 citations. A total of 39 research reports that met the predefined criteria were analyzed. Mental pain, communication difficulties, decision-making impulsivity, and aggression, as well as several demographic variables, were found to be major risk factors for SSAs. LIMITATIONS: We found a variability of definitions for SSA that hamper the ability to draw a model for the risk factors and processes that facilitate it. Moreover, the role of suicide intent and planning in SSA is still unclear. Further studies should aim to clarify and refine the concepts and measures of SSA, thereby enabling more specific and concrete modeling of the psychological element in its formation. CONCLUSION: SSA is a distinguishable phenomenon that needs to be addressed specifically within the scope of suicidal behavior. Interpersonal problems, as well as impulsivity and aggression, seem to facilitate SSA when mental pain serves as a secondary factor. Healthcare professionals should be aware of SSA, and familiar with its specific risk factors. Moreover, psychological and suicidal risk assessment should include a designated evaluation of these risk factors as part of intervention and prevention models for SSA.

Predictive value of psychological characteristics and suicide history on medical lethality of suicide attempts: A follow-up study of hospitalized patients.

BACKGROUND: This study examined the role of mental pain, communication difficulties, and suicide history in predicting the medical severity of follow-up suicide attempts. METHODS: The cohort included 153 consecutive psychiatric in-patients who participated in earlier studies 1-9 years previously. Fifty-three had a history of a medically serious suicide attempt (MSSA), 64 had a history of a medically non-serious suicide attempt (MNSSA), and 36 had no history of suicide. A MSSA was defined as a suicide attempt that warranted hospitalization for at least 24h and extensive medical treatment. Participants completed a battery of instruments measuring mental pain and communication difficulties. Findings were analyzed in relation to follow-up suicide attempts and their severity. RESULTS: Fifty-three patients (35.5%) had attempted suicide: 15 (9.9%) a MSSA (including 5 fatalities) and 38 (25%) a MNSSA. The medical severity of the index attempt and level of hopelessness at the index attempt were significantly correlated with medical severity of the follow-up attempt. In younger patients, high levels of depression and self-disclosure predicted the medical severity of the follow-up attempt. In patients with relatively low hopelessness, the medical severity of the attempt increased with the level of self-disclosure. LIMITATIONS: (i) Possibly incomplete patient information, as some of the patients who participated in the index studies could not be located. (ii) Relatively small group of patients with an index MSSA. CONCLUSIONS: Patients who have made a suicide attempt should be assessed for medical severity of the attempt, hopelessness, and communication difficulties, which are important factors in follow-up attempts.

On the role of impulsivity and decision-making in suicidal behavior.

Suicide risk constitutes a complex set of interacting demographic, clinical, psychobiological and environmental variables. Impulsivity is a long-known risk factor for suicide attempts. However, research based on clearer conceptual refinement in this area is imperative. One emerging field of study is that of decision-making. Impulsivity involves a failure of higher-order control, including decision-making. Using standardized operational definitions that take into consideration relevant aspects of impulsivity, including state- and trait-components and a deeper understanding of the process of decision-making in the suicidal mind, we may come a step closer to understanding suicidality and winning the fight in this scourge of human suffering.

A proposed model of the development of suicidal ideations.

BACKGROUND: Suicidal ideations may precede suicide attempts. They are of particular concern in psychiatric populations because psychopathology is a major risk factor for suicide. The factors affecting the development of suicide ideations may differ among psychiatric patients with and without a previous suicide attempt and individuals without a psychiatric diagnosis. OBJECTIVES: The aim of this study is to develop a model of suicide ideation in psychiatric patients and the general population. METHOD: The study included 196 participants: 92 psychiatric patients with a previous suicide attempt ("attempters"); 47 psychiatric patients who had never attempted suicide ("non-attempters"); and 57 healthy control subjects. Data were collected on socio-demographic parameters, clinical history, and details of the suicide attempts. Participants completed a battery of psychological instruments assessing aggression-impulsivity, mental pain (including depression and hopelessness) and communication difficulties, in addition to negative life events. Findings were correlated with suicidal ideation by group. RESULTS: The correlations of the different variables with suicidal ideation differed between suicide attempters and non-attempters; therefore, the model was analyzed separately for each group. The study yielded three major findings: negative life events had a significant effect on both anger-in and impulsivity in non-attempters but not in attempters; hopelessness moderately contributed to suicidal ideations in attempters but not in non-attempters; loneliness contributed significantly to depression in non-attempters but was less distressing in attempters. CONCLUSION: The mechanism underlying suicidal ideation appears to differ between psychiatric patients who have previously attempted suicide and those who have not, supporting a dual model of suicidal ideation. Although this is only a preliminary study, these findings are important for furthering our understanding of the process of transition of suicidal thoughts to completion of suicide. These results need further replication with a larger cohort of subjects.
