Abstract
PURPOSE Psychache significantly contributes to the suicidal process. However, the transition from pre-suicidal suffering to a suicide crisis remains one of the least explored stages in suicidology. METHODS We retrospectively explored experience of pre-suicidal suffering through semi-structured, in-depth interviews with 12 individuals recruited from the Vilnius City Mental Health Center, Lithuania. Interpretative phenomenological analysis was employed to identify recurring patterns. RESULTS Nine primary group experiential themes emerged: Certain adverse life events occurring during the suicidal process were not immediately perceived as connected; Complex traumatic events laid the groundwork for a profound sense of lack; A compensatory mechanism balanced the experience of profound lack; Exhaustion ensued from efforts to sustain the compensatory mechanism; The main trigger directly challenged the compensatory mechanism; The affective state followed the experience of the main triggering event; Dissociation served to isolate psychache; Thoughts of suicide experienced as automatic; Suicide was perceived as a means to end suffering. CONCLUSION The findings suggest that the suicidal process unfolds over an extended period of suffering, culminating in a crisis to alleviate unbearable psychological pain. In clinical practice, identifying the main triggering event discussed in this study can be pivotal in understanding the essence of suffering characterized by profound lacking and developed compensatory mechanisms.

Abstract
OBJECTIVE Dissociative symptoms are both a pathological consequence of exposure to psychological trauma as well as a side effect of N-methyl-d-aspartate (NMDA) receptor antagonist medications; therefore, accurate and valid assessment of these symptoms is important. The psychometric properties of the 23-item Clinician Administered Dissociative States Scale (CADSS) have been characterized in the ketamine and esketamine literatures. Here, we examine its performance in a sample with and without posttraumatic stress disorder (PTSD) and a history of exposure to psychological trauma. METHODS Participants with a history of psychological trauma with (N = 148) and without (N = 100) the diagnosis of PTSD and healthy participants without a psychiatric disorder or history of trauma (N = 28) were assessed with the 23-item CADSS and other psychometric and neuropsychological assessments. Analyses were performed to examine internal consistency, convergent and discriminant validity, factor structure, differential performance in populations reported to be more or less likely to report dissociative symptoms (e.g., patients with and without PTSD), and sensitivity to change resulting from exposure to trauma-related sights and sounds. RESULTS The 23-item CADSS was found to have high internal consistency (Cronbach's alpha 0.91) and a single-factor structure. CADSS total scores in trauma-exposed participants with PTSD were higher than those in trauma-exposed participants without PTSD and non-traumatized non-PTSD participants. Finally, veterans with Iraq combat-related PTSD showed a significant increase in CADSS total score after exposure to combat-related slides and sounds. CONCLUSION The 23-item CADSS, already validated as a tool to measure dissociation related to administration of NMDA receptor antagonist medication, performs in a reliable and valid manner in the assessment of dissociation in psychologically traumatized participants.

Abstract
Self-dehumanization, a phenomenon relevant to social psychology, has been somewhat absent from clinical psychology research. Furthermore, measures of self-dehumanization are few, and to our knowledge, no validated and generalizable self-report measure exists. To address this gap, we present a Self-Dehumanization Scale (SDS). This work incorporates evidence from three studies examining the reliability, validity, and factor structure of the SDS in an undergraduate sample, a clinically relevant community sample, and a sample with at least one minoritized identity. The SDS was derived from dehumanization theory and was developed to measure animalistic and mechanistic self-dehumanization. All studies suggested an 8-item SDS, with Study 1 suggesting a single-factor solution with, however, some indication of a two-factor structure, and Studies 2 and 3 affirming a two-factor solution. The SDS, and its respective factors, generally showed discriminant validity from related, yet distinct, measures of self-hate, self-esteem (Study 2), dissociation, and measures of discrimination (in Study 3). Finally, animalistic and mechanistic SDS showed somewhat mixed but promising evidence regarding their associations to minoritized identities and to symptoms of depression, and suicide risk, above and beyond each study's fairly stringent control variables. Thus, self-dehumanization may prove to be a clinically promising leverage point in assessing psychopathology, particularly among minoritized communities.

Abstract
Non-suicidal self-injury (NSSI) can both precede and co-occur with suicidal attempts (SA). Underlying mechanisms/factors leading to the transition to SA in NSSI youths have been proposed (including the role of social cognition), despite they should be yet confirmed. Therefore, the study aims at exploring the role of the Theory of Mind in the differentiation of a sample of NSSI youngsters (aged 15-24) according to the presence of SA. We divided the sample into 4 groups using the Deliberate Self Harm Inventory (DSHI) and Columbia Suicide Severity Rating Scale (C-SSRS): control group (notNSSInotSA), NSSI without SA (NSSInotSA), NSSI with SA (NSSIplusSA), and SA without NSSI (SAonly). NSSIplusSA patients displayed higher Reading the Mind in the Eyes Test (RMET) scores (indicative of ToM abilities) than both the NSSInotSA (p=0.0016) and SAonly groups (p=0.0198), while SAonly patients showed lower RMET scores compared to the control group (p=0.0214). Multiple regression models used to differentiate NSSInotSA and NSSIplusSA found a significant association between RMET and LOSCS-CSC (Level Of Self-Criticism Scale-Comparative Self-Criticism) (pC=0.0802, pD=0.0016, pG=0.0053). Our findings supported the hypothesis that a hypertrophic affective ToM may possibly be associated with the occurrence of SA in youth NSSI. Further larger and longitudinal studies should confirm these preliminary findings, by exploring all social cognition dimensions.

Abstract
Psychotic-like experiences (PLEs) have been associated with poor sleep quality and increased suicide risk. However, the association between PLEs, insomnia and suicide risk has not been thoroughly investigated in prior studies. In this study, we aimed to explore as to whether insomnia moderates the association between PLEs and suicidal ideation. The study was performed in 4203 young adults (aged 18-35 years, 63.8% females). Data were collected using self-reports. Moderation analysis demonstrated that PLEs are associated with higher levels of the current suicidal ideation only in participants with greater severity of insomnia (B = 0.003, p < 0.001). This analysis included age, gender, education, occupation and depressive symptoms as covariates. Moreover, the network analysis demonstrated that nodes representing PLEs are connected to the node of current suicidal ideation only in participants with greater severity of insomnia. The nodes of PLEs connected to the current suicidal ideation node captured PLEs representing deja vu experiences, auditory hallucination-like experiences and paranoia (edge weights between 0.011 and 0.083). Furthermore, nodes representing PLEs were the three most central nodes in the network analysis of individuals with higher levels of insomnia (strength centrality between 0.96 and 1.10). In turn, the three most central nodes were represented by depressive symptoms in the network analysis of individuals with lower levels of insomnia (strength centrality between 0.67 and 0.79). Findings from this study indicate that insomnia might be an important risk factor of suicide in people with PLEs, especially those reporting deja vu experiences, auditory hallucination-like experiences and paranoia.

Aberrant salience in cannabis-induced psychosis: a comparative study. Front Psychiatry 2024; 14:1343884.

Abstract
Background Natural Cannabis (NC) and Synthetic Cannabinoids (SCs) use can increase the risk and exacerbate the course of psychotic disorders. These could be influenced by the Aberrant Salience (AS) construct. It refers to an excess of attribution of meaning to stimuli that are otherwise regarded as neutral, thereby transform them into adverse, dangerous, or mysterious entities. This leads the patient to engage in aberrant and consequently incorrect interpretative efforts concerning the normal perception of reality and its relationship with our analytical abilities. AS appears to play a significant role in the onset and perpetuation of psychotic disorders. The internal conflict arising from aberrant attributions of significance leads to delusional thoughts, ultimately culminating in the establishment of a self-sustaining psychosis. Aims To examine the differences between psychoses course not associated with cannabis use and those associated with NC-use and SCs-use, in terms of psychotic and dissociative symptoms, AS, global functioning and suicidal ideation. Methods A sample of 62 patients with First Episode Psychosis (FEP) was divided into 3 groups: non cannabis users (non-users, N = 20); NC-users or rather Delta-9-tetrahydrocannabinol (THC) users (THC-users, N = 21); SCs-users, commonly referred to as SPICE-users (SPICE-users, N = 20). Each group underwent assessments at the onset of psychotic symptoms, as well as at the 3 months and 6 months marks, utilizing a range of psychopathological scales. These included the Positive and Negative Syndrome Scale (PANSS) for investigating psychotic symptoms, the Global Assessment of Functioning (GAF) scale for assessing overall functioning, the Dissociative Experiences Scale (DES-II) for measuring dissociative symptoms, the Scale for Suicide Ideation (SSI) for evaluating suicidal ideation and the Aberrant Salience Inventory (ASI) scale for gauging AS. Results SPICE-users showed more severe and persistent positive symptoms, while negative symptoms were mostly represented among non-users. Non-users showed better recovery than SPICE-users in global functioning. All groups showed a decrease in both ASI scores and subscale scores. SPICE-users exhibited higher global AS scores and less improvement in this aspect compared to other groups. Conclusion This study may help understanding the role of AS in both non-substance-related and substance-induced psychosis. This knowledge may lead clinician to a better diagnosis and identify patient-tailored psychopharmacological treatment.

Abstract
BACKGROUND Previous studies have indicated that borderline personality disorder (BPD) is closely associated with trauma and dissociation. Nevertheless, BPD is a heterogeneous condition, and not all people with BPD have severe dissociation. This study examined whether the relationship of BPD features with trauma and dissociation would remain significant after controlling for some general non-specific mental health distress. We also made the first attempt to explore which specific BPD features would be particularly associated with dissociation. METHODS We analyzed survey data from a sample of community health service users in Hong Kong (N = 376). Hierarchical multiple regression and data-driven network analysis were used. RESULTS The lifetime prevalence of DSM-5 BPD was 16.0% in our sample. Of participants who met criteria for BPD, 43.3% scored above cutoff on the dissociation measures, thus possibly having clinically significant dissociative symptoms. BPD features were associated with adulthood trauma and psychoform dissociation even after controlling for age, depression and self-esteem. Network analysis showed that some BPD features - including impulsivity, identity disturbance and suicidal/self-mutilation behaviors - were particularly associated with dissociation; other BPD features such as interpersonal-related problems had relatively weak to no connection with dissociation. CONCLUSIONS Our results suggested that some particular BPD features might be dissociative in nature, although further longitudinal research is required. We argue that a trauma-informed perspective should be employed when working with clients presenting with BPD features despite these features being commonly stigmatized. Further research on the intervention needs of the people with BPD who suffer from high levels of dissociation is required.

Abstract
BACKGROUND Individuals with eating disorders (EDs) often struggle with markedly low self- esteem and are at risk for suicidal behavior. Dissociation and perceived burdensomeness are often cited as facilitators of suicidal outcomes. Specifically, perceived burdensomeness is comprised of self-hate and liability on others, although it remains unclear which variables most heavily influence suicidal behavior in EDs. METHODS In a sample of 204 women with bulimia nervosa, the present study examined the potential impact of self-hate and dissociation on suicidal behavior. We hypothesized that suicidal behavior would be equally, and potentially more strongly, related to self-hate than dissociation. Regression analyses investigated the unique effects of these variables on suicidal behavior. RESULTS Consistent with our hypothesis, a significant relationship emerged between self-hate and suicidal behavior (B = 0.262, SE = 0.081, p < .001, CIs = 0.035-0.110, R-squared =0.07) but not between dissociation and suicidal behavior (B = 0.010, SE = 0.007, p = .165, CIs = -0.389-2.26, R-squared =0.010). Additionally, when controlling for one another, both self-hate (B = 0.889, SE = 0.246, p < .001, CIs = 0.403-1.37) and capability for suicide (B = 0.233, SE = 0.080, p = .004, CIs = 0.076-0.391) were uniquely and independently associated with suicidal behavior. LIMITATIONS Future work should include longitudinal analyses to understand temporal relationships among study variables. CONCLUSIONS In sum, when considering suicidal outcomes, these findings support a view that highlights personal loathing rooted in self-hate rather than de-personalizing aspects of dissociation. Accordingly, self-hate may emerge as a particularly valuable target for treatment and suicide prevention in EDs.

Abstract
Upto 86% of dissociative individuals engage in non-suicidal self-injury (NSSI). Research suggests that people who dissociate utilize NSSI to regulate posttraumatic and dissociative experiences, as well asrelated emotions. Despite high rates of NSSI, no quantitative study has examined the characteristics, methods, and functions of NSSIwithin a dissociative population. The present study examined thesedimensions of NSSI among dissociative individuals, as well aspotential predictors of intrapersonal functions of NSSI. The sample included 295 participants who indicated experiencing one or more dissociative symptoms and/or having been diagnosed with a trauma- or dissociation-related disorder. Participants were recruited through online trauma- and dissociation- related forums. Approximately 92% of participants endorsed a history of NSSI. The most common methods of NSSI were interfering with wound healing (67%), hitting oneself (66%), and cutting (63%). After controlling for age and gender, dissociation was uniquely associated with cutting, burning, carving, interfering with wound healing, rubbing skin against rough surfaces, swallowing dangerous substances, and other forms of NSSI. Dissociation was correlated with affect regulation, self-punishment,anti-dissociation, anti-suicide, and self-care functions of NSSI;however, after controlling for age, gender, depressive symptoms, emotion dysregulation, and PTSD symptoms, dissociation was no longer associated with any function of NSSI. Instead, only emotion dysregulation was associated with the self-punishment function ofNSSI and only PTSD symptoms were associated with the anti-dissociation function of NSSI. Understanding the unique properties of NSSI among dissociative individuals may improve the treatment of people who dissociate and engage in NSSI.

Abstract
BACKGROUND Natural Cannabis (NC) and Synthetic Cannabinoids (SCs) use can increase the risk of developing psychotic disorders and exacerbate their course. AIMS To examine the differences between psychoses not associated with cannabis use and those associated with NC and SCs use, evaluating psychotic symptoms, global functioning, dissociative symptoms and suicidal ideation. METHODS The sample of 61 patients with First Episode Psychosis (FEP) was divided into 3 groups: non-Cannabis users (non-users, N = 20); NC users (THC-users, N = 21); SCs users (SPICE-users, N = 20). Each group was assessed at FEP and after 3 and 9 months through specific psychopathological scales. RESULTS THC-users, and even more SPICE-users, displayed much more severe positive symptoms than non-users. Negative symptoms were higher among non-users. After 9 months the non-users had recovered significantly better than SPICE-users in their global functioning. Dissociative symptoms were significantly greater in substance users. Finally, suicidal ideation was higher in SPICE-users than in both THC-users and non-users. DISCUSSION The psychoses induced by NC and SCs showed different symptomatic pictures and outcomes from each other and when compared to the psychoses not associated with the use of substances; such knowledge could be relevant in identifying a specific drug treatment.

Abstract
Objective: Dissociative symptoms are considered risk factors for suicide and non-suicidal self-injury (NSSI). In this study, the relationship between suicidal behaviors and NSSI with dissociative symptoms in adolescents with a history of Child Sexual Abuse (CSA) was investigated. Methods: A total of 100 adolescents with a history of CSA were evaluated with a detailed forensic psychiatric interview. Dissociative symptoms were measured with the self-report Adolescent Dissociative Experiences Scale (A-DES) and the parent-reported Child Dissociative Checklist (CDC). Results: While dissociative symptoms did not differ between adolescents with and without suicide attempts (CDC; p = .068 and A-DES; p = .060), they were significantly higher in adolescents with non-suicidal self-harming behavior (CDC; p < .001 and A-DES; p = .001). Suicide attempts and NSSI were more common in those who reported genital touching as a type of sexual abuse (respectively, p = .003; p = .048). In regression analysis; history of psychiatric treatment (OR = 9.09 [95% CI = 1.52, 54.29]) and NSSI (OR = 8.18 [95% CI = 2.01, 33.23]) were independently associated with suicide attempts. In addition, parent-reported dissociative symptoms (CDC scores) (OR = 1.27 [95% CI = 1.06, 1.53] and suicide attempt (OR = 8.09 [95%CI = 1.96,33.42] showed independent association with NSSI. Conclusions: Dissociative symptoms may be predictive factors for NSSI and should be considered in risk assessment of adolescents with a history of CSA.

Abstract
Background: Suicide is a leading cause of death, and rates of attempted suicide have increased during the COVID-19 pandemic. The under-diagnosed psychiatric phenotype of dissociation is associated with elevated suicidal self-injury; however, it has largely been left out of attempts to predict and prevent suicide.Objective: We designed an artificial intelligence approach to identify dissociative patients and predict prior suicide attempts in an unbiased, data-driven manner.Method: Participants were 30 controls and 93 treatment-seeking female patients with posttraumatic stress disorder (PTSD) and various levels of dissociation, including some with the PTSD dissociative subtype and some with dissociative identity disorder (DID).Results: Unsupervised learning models identified patients along a spectrum of dissociation. Moreover, supervised learning models accurately predicted prior suicide attempts with an F1 score up to 0.83. DID had the highest risk of prior suicide attempts, and distinct subtypes of dissociation predicted suicide attempts in PTSD and DID.Conclusions: These findings expand our understanding of the dissociative phenotype and underscore the urgent need to assess for dissociation to identify individuals at high-risk of suicidal self-injury.

Abstract
BACKGROUND Cannabis is the most widely used illegal drug but is rarely considered a causal factor in death. AIMS This study aimed to understand trends in deaths in England where cannabinoids were detected at post-mortem, and to evaluate the clinical utility of post-mortem cannabinoid concentrations in coronial investigations. METHODS Deaths with cannabinoid detections reported to the National Programme on Substance Abuse Deaths (NPSAD) were extracted and analysed. RESULTS From 1998 to 2011, on average 7% of all cases reported to NPSAD had a cannabinoid detected (n = 110 deaths per year), rising to 18% in 2020 (n = 350). Death following cannabis use alone was rare (4% of cases, n = 136/3455). Traumatic injury was the prevalent underlying cause in these cases (62%, n = 84/136), with cannabis toxicity cited in a single case. Polydrug use was evident in most cases (96%, n = 3319/3455), with acute drug toxicity the prevalent underlying cause (74%, n = 2458/3319). Cardiac complications were the most cited physiological underlying cause of death (4%, n = 144/3455). The median average Δ9-tetrahydrocannabinol post-mortem blood concentrations were several magnitudes lower than previously reported median blood concentrations in living users (cannabis alone: 4.3 µg/L; cannabis in combination with other drugs: 3.5 µg/L). CONCLUSIONS Risk of death due to cannabis toxicity is negligible. However, cannabis can prove fatal in circumstances with risk of traumatic physical injury, or in individuals with cardiac pathophysiologies. These indirect harms need careful consideration and further study to better elucidate the role cannabis plays in drug-related mortality. Furthermore, the relevance of cannabinoid quantifications in determining cause of death in coronial investigations is limited.

Abstract
BACKGROUND Studies have reported elevated rates of dissociative symptoms and comorbid dissociative disorders in functional neurological disorder (FND); however, a comprehensive review is lacking. AIMS To systematically review the severity of dissociative symptoms and prevalence of comorbid dissociative disorders in FND and summarise their biological and clinical associations. METHOD We searched Embase, PsycInfo and MEDLINE up to June 2021, combining terms for FND and dissociation. Studies were eligible if reporting dissociative symptom scores or rates of comorbid dissociative disorder in FND samples. Risk of bias was appraised using modified Newcastle-Ottawa criteria. The findings were synthesised qualitatively and dissociative symptom scores were included in a meta-analysis (PROSPERO CRD42020173263). RESULTS Seventy-five studies were eligible (FND n = 3940; control n = 3073), most commonly prospective case-control studies (k = 54). Dissociative disorders were frequently comorbid in FND. Psychoform dissociation was elevated in FND compared with healthy (g = 0.90, 95% CI 0.66-1.14, I2 = 70%) and neurological controls (g = 0.56, 95% CI 0.19-0.92, I2 = 67%). Greater psychoform dissociation was observed in FND samples with seizure symptoms versus healthy controls (g = 0.94, 95% CI 0.65-1.22, I2 = 42%) and FND samples with motor symptoms (g = 0.40, 95% CI -0.18 to 1.00, I2 = 54%). Somatoform dissociation was elevated in FND versus healthy controls (g = 1.80, 95% CI 1.25-2.34, I2 = 75%). Dissociation in FND was associated with more severe functional symptoms, worse quality of life and brain alterations. CONCLUSIONS Our findings highlight the potential clinical utility of assessing patients with FND for dissociative symptomatology. However, fewer studies investigated FND samples with motor symptoms and heterogeneity between studies and risk of bias were high. Rigorous investigation of the prevalence, features and mechanistic relevance of dissociation in FND is needed.

Dissociative experiences among Lebanese university students: Association with mental health issues, the economic crisis, the COVID-19 pandemic, and the Beirut port explosion. PLoS One 2022; 17:e0277883. [PMID: 36399459 PMCID: PMC9674130 DOI: 10.1371/journal.pone.0277883] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 11/06/2022] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Dissociative experiences are psychological manifestations characterized by a loss of connection and continuity between thoughts, emotions, environment, behavior, and identity. Lebanon has been facing indescribable events in the last few years, including the COVID-19 pandemic, the Beirut explosion, a crushing economic crisis with the highest inflation rate the country has known in over three decades. The aim of this study was to evaluate the correlation between dissociative experiences and post-traumatic stress symptoms from the economic crisis, the Beirut blast, the COVID-19 pandemic, and other mental health issues in a sample of Lebanese university students. METHODS This cross-sectional study enrolled 419 active university students (18-35 years) from all over Lebanon (May and August 2021). The respondents received the online soft copy of a survey by a snowball sampling technique through social media and messaging apps. The questionnaire included sociodemographic data, the Dissociative Experience Scale (DES-II), the PTSD Checklist Specific Version (PCL-S), the Financial Wellbeing Scale, the Beirut Distress Scale, the Lebanese Anxiety Scale, the Patient Health Questionnaire. RESULTS The two-factor model of the DES fitted best according to CFI, RMSEA and χ2/df values, but modestly according to TLI. The two factors were absorption and amnesia/depersonalization. Higher stress (Beta = 0.95) and more PTSD from the Beirut blast (Beta = 0.29) and from the economic crisis (Beta = 0.23) were significantly associated with more absorption. A personal history of depression (Beta = 6.03), higher stress (Beta = 0.36) and more PTSD from the Beirut blast (Beta = 0.27) and from the COVID-19 pandemic (Beta = 0.16) were significantly associated with more amnesia/depersonalization. CONCLUSION Significant rates of dissociative experiences and their sub-manifestations (amnesia/depersonalization and absorption) were found among Lebanese university students, with remarkable co-occurrence of a traumatic/stressful pattern, whether on an individual (history of PTSD) or a collective level (Post-traumatic manifestations from Beirut blast, COVID-19 pandemic and/or economic crisis), or whether correlated to an acute single event or to certain chronic stressors, or even to a personal history of depression. Such findings must raise the attention to serious mental and psychosocial alteration in the Lebanese national identity.

Abstract
Our aim was to examine U.S. national prevalence of pathological dissociation (PD) likely indicative of dissociative disorder, and associated morbidity, comorbidity, and childhood maltreatment. PD was assessed in 6,644 participants in the National Comorbidity Survey Replication, a nationally representative adult survey. Seven of the eight pathological dissociation taxon items were inquired about over the past month and scored on a 4-point scale. A conservative PD cutoff score was applied, with 100% specificity against healthy individuals and 84% sensitivity for Depersonalization Disorder which lies at the less severe end of the dissociative disorder spectrum; it yielded a national PD prevalence of 4.1%. The PD group had diminished physical and mental health, marked comorbidity with most major psychiatric disorders, and high likelihood of psychiatric hospitalization. Over half of PD members had attempted suicide, significantly more than individuals with lifetime major depression. Childhood maltreatment was quantified for physical abuse, witnessing domestic violence, physical neglect, emotional abuse, and emotional neglect. Total childhood trauma significantly positively predicted PD severity, as well as severity of all three pathological dissociative experiences (amnesia, depersonalization / derealization, identity alteration). Furthermore, each childhood trauma category significantly predicted PD severity uniquely and additively. Childhood maltreatment in the PD group was significantly greater than in lifetime major depression, except for similar emotional neglect, and was comparable to lifetime PTSD. The study reinforces the validity of prior PD findings across clinical and community samples, and highlights the need for increased attention toward diagnosing and treating these quite common and highly morbid disorders and their traumatic antecedents.

Abstract
INTRODUCTION The current study aimed to explicate the role of dissociation in the capability and suicide relationship by examining how lifetime and state-based acute dissociation contributes to capability for suicide using a multi-method approach of self-report and augmented reality (AR) laboratory tasks. METHOD Participants (N = 145) were students recruited for course credit at a southern university. Participants completed self-report and laboratory AR dissociative induction tasks. Correlations and mediation analyses were conducted to test hypotheses using SPSS v. 26 and PROCESS Macro. RESULTS There was a significant indirect effect on capability and suicidal ideation via acute dissociation (β = 0.035, SE = 0.02, 95% CI = 0.001, 0.095). Additionally, there was a significant indirect effect on capability and suicide attempt(s) via dissociation (β = 0.19, SE = 0.10, 95% CI = 0.044, 0.449). CONCLUSIONS As prior theories suggest, dissociation may augment feeling disconnected from the body and may temporarily impact capability to render a suicidal act as more probable. The presence of dissociation after a painful and provocative attempt may increase capability and pain tolerance. Implications of these findings include the consideration of dissociation as a pertinent factor in the assessment and treatment of suicide and the role of AR in aiding the exploration of suicide correlates.

Abstract
BACKGROUND Childhood trauma and affective disorders are known risk factors for adult suicidal behavior. Studies have shown a mediating effect of insecure attachment on the effect of childhood trauma and suicidal behavior but so far it is not clear whether this effect is related to an attachment dimension (anxiety, avoidance). AIM The present study sought to examine the mediating effect of attachment anxiety and avoidance on suicidal behavior. METHODS We analyzed data on childhood trauma, attachment style, depression severity, presence of prior suicide attempts and current suicide ideation from 96 patients diagnosed with an affective disorder. Two mediation analyses were conducted to assess the effect of childhood trauma on 1) prior suicide attempts and 2) current suicidal ideation through its effect on attachment. RESULTS We found that childhood trauma had a complete mediated effect on the presence of prior suicide attempts through its effect on avoidant attachment (a1b1 = 0.0120, 95%-CI [0.0031, 0.0276]). However, only emotional abuse had a direct influence on suicidal ideation (c' = 0.0273, p < 0.01) without any indirect effect of anxious or avoidant attachment. LIMITATIONS Variables were not assessed in a prospective way and sample size was small. CONCLUSIONS Our findings suggest that individuals with avoidant attachment and childhood trauma are likely to present a high suicide risk. Since avoidant attachment is associated with altered perceptions and eventual rejection of social support, we recommend to screen for attachment early and to engage patients in therapeutical approaches focusing on the client-therapist alliance.

Abstract
BACKGROUND AND HYPOTHESIS Children who endorse psychotic-like experiences (PLEs) appear to be at a greater risk for suicidal ideation and behavior (SI/SB) compared to their peers who do not endorse PLEs. Despite evidence of differential relations among subtypes of PLEs and SI/SB, the research on which PLE subtypes produce the strongest associations remains mixed. Further, though there is evidence that general psychological distress may help explain the relation between PLEs and SI/SB, no research has investigated the role of distress specific to PLEs in this association. STUDY DESIGN The present study sought to assess the associations among individual Prodromal Questionnaire-Brief Child Version (PQ-BC) items and SI/SB, as well as to explore the role of distress associated with PLEs as a mediator and/or moderator in a demographically diverse sample of children across the United States (N = 11 875). STUDY RESULTS Results revealed that individual items of the PQ-BC may be differentially predictive of lifetime SI (ßs = 0.000-0.098) and SB (ßs=0.002-0.059), even when controlling for sociodemographic variables, internalizing symptoms, and traumatic experiences, with particularly strong associations observed among items indexing thought control, auditory hallucinations, suspiciousness, and nihilistic thinking/dissociative experiences. Item 13, nihilistic thinking/dissociative experiences, displayed the strongest effect sizes. Findings from moderation and mediation models provided evidence consistent with distress as both a partial mediator and moderator of the relation between total PLEs and individual PQ-BC items with SI and SB. CONCLUSIONS Distress specific to PLEs may be an important modifiable risk factor to target in suicide assessment, prevention, and intervention efforts.

Abstract
OBJECTIVES To test the hypothesis that people with concurrent diagnosis of epilepsy and psychogenic nonepileptic seizures (PNES) are at increased risk of attempting suicide as compared to people with epilepsy or PNES alone. To report on suicide rates. METHODS Retrospective cohort study from the UK largest tertiary mental health care provider, with linked nationwide admission and mortality data from the Hospital Episode Statistics and Office for National Statistics. Participants were 2460 people with a primary or secondary diagnosis of epilepsy, PNES or concurrent epilepsy and PNES attending between 1 January 2007 and 18 June 2021. The primary outcome was a first hospital admission for suicide attempt (International Classification of Diseases, version 10 X60-X84). RESULTS 9% of participants had at least one suicide attempt-related hospital admission. For people with concurrent diagnosis of epilepsy and PNES, the odds for suicide attempt-related admissions were 2.52 times the odds of people with epilepsy alone (OR 0.40; 95% CI 0.21 to 0.79; p=0.01). Odds were comparable between people with concurrent diagnosis and people with PNES alone (OR 0.75; 95% CI 0.41 to 1.48; p=0.40). Post hoc analyses revealed that the odds of people with PNES alone were 1.93 times the odds of people with epilepsy alone (OR 0.52; 95% CI 0.38 to 0.70; p<0.001). CONCLUSIONS People with concurrent diagnosis of epilepsy and PNES or PNES alone have significantly increased odds of hospitalisation due to suicide attempt as compared to people with epilepsy alone (152% and 93% increase, respectively). These findings have direct implications for the clinical management of suicide risk in people with epilepsy.

Problematic Use of the Internet Mediates the Association between Reduced Mentalization and Suicidal Ideation: A Cross-Sectional Study in Young Adults. Healthcare (Basel) 2022; 10:healthcare10050948. [PMID: 35628085 PMCID: PMC9140488 DOI: 10.3390/healthcare10050948] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 05/03/2022] [Accepted: 05/09/2022] [Indexed: 12/24/2022] Open
Abstract
Suicide is a major public health problem, and it is urgent to investigate its underlying clinical and psychological concomitants. It has been suggested that low mentalization skills and problematic use of the internet (PUI) are factors that can play a role in suicidal behaviors. It is possible that poor mentalization skills contribute to leading to forms of PUI, which, in turn, can represent triggers for suicidal ideation (SI). We tested this hypothesis through a quantitative and cross-sectional study on a sample (n = 623) of young adults (age range: 18−34). Self-report measures investigating symptoms related to Social Media Addiction (SMA), Internet Gaming Disorder (IGD), mentalization capacity, and SI were used. A single mediation analysis with two mediators was carried out to evaluate the direct and indirect effects of mentalization on SI through the mediating role of SMA- and IGD-related symptoms, controlling for potential confounding factors (e.g., socio-demographic and addiction-related variables). The four explored variables were significantly associated with each other (all p < 0.001) across all subjects; the mediational model showed that the total effect of mentalization on SI was significant (B = −0.821, SE = 0.092 (95% CI: −1.001; −0.641)) and that both SMA- (B = −0.073, SE = 0.034 (95% CI: −0.145; −0.008)) and IGD-related symptoms (B = 0.046, SE = 0.027 (95% CI: −0.107; −0.001)) were significant mediators of such association. Our findings support the possibility that PUI severity plays a relevant role in mediating the association between low mentalization skills and levels of SI.

Abstract
Dissociative disorders are a common and frequently undiagnosed group of psychiatric disorders, characterized by disruptions in the normal integration of awareness, personality, emotion and behavior. The available evidence suggests that these disorders arise from an interaction between genetic vulnerability and stress, particularly traumatic stress, but the attention paid to the underlying genetic diatheses has been sparse. In this paper, the existing literature on the molecular genetics of dissociative disorders, as well as of clinically significant dissociative symptoms not reaching the threshold of a disorder, is reviewed comprehensively across clinical and non-clinical samples. Association studies suggest a link between dissociative symptoms and genes related to serotonergic, dopaminergic and peptidergic transmission, neural plasticity and cortisol receptor sensitivity, particularly following exposure to childhood trauma. Genome-wide association studies have identified loci of interest related to second messenger signaling and synaptic integration. Though these findings are inconsistent, they suggest biologically plausible mechanisms through which traumatic stress can lead to pathological dissociation. However, methodological concerns related to phenotype definition, study power, and correction for the confounding factors limit the value of these findings, and they require replication and extension in studies with better design.

Abstract
Non-suicidal self-injury (NSSI) is a clinically significant behavior with high relevance and prevalence, especially affecting approximately 17-18% of the adolescent population worldwide. The aim of this study is to perform a systematic review to evaluate the effectiveness of the available Specific Psychotherapeutic Interventions (SPI) focused on the reduction of NSSI behaviors. A systematic review was performed analyzing PsychINFO, MEDLINE, Web of Science, PubMed and Cochrane CentralRegister of Controlled Trials to identify studies of interest from January 2010 to December 2020. According to PRISMA guidelines, only 13 studies were included in the review. Six SPI were found to specifically and significantly reduce NSSI in adolescents: Developmental Group Psychotherapy (DGP), Therapeutic Assessment (TA), Cutting Down Program (CDP), Emotional Regulation Individual Therapy for Adolescents (ERITA), Treatment for Self-Injurious Behaviors (T-SIB) and Intensive Contextual Treatment (ICT). Furthermore, relevant improvements in anxiety and depression symptoms were observed. The results of this review demonstrate the effectiveness of these interventions, mainly the CPD and T-SIB, which are the only SPI that have been studied using Randomized Controlled Trial (RCT). Considering the clinical relevance and associated functional impairment of NSSI, more research is needed to replicate the results and to increase knowledge about SPIs.

Abstract
Epidemiological studies have suggested that childhood maltreatment increases suicidal ideation, and dissociative symptoms and hopelessness are involved in this relation. To better address this issue, we used a path analysis model to examine the role of different types of childhood maltreatment on suicidal ideation, investigating whether hopelessness and dissociative symptoms mediated this relation. A sample of 215 adult psychiatric inpatients was enrolled between January 2019 and January 2020, at the psychiatric unit of Sant’Andrea Medical Center in Rome, Italy. The Childhood Trauma Questionnaire (CTQ), Beck Hopelessness Scale (BHS), Dissociative Experiences Scale (DES-II), and Columbia-Suicide Severity Rating Scale (C-SSRS) were used to test the hypotheses. Results revealed that the presence of sexual abuse directly affected suicidal ideation (β = 0.18, SE = 0.8, p < 0.05), while emotional abuse and neglect indirectly increased suicidal ideation via dissociation (β = 0.05, SE = 0.02, 95% C.I. 0.01/0.09) and hopelessness (β = 0.10, SE = 0.03, 95% C.I. = 0.04/0.16). Professionals working with children should be aware of the long-term consequences of childhood maltreatment, particularly suicide risk. Furthermore, professionals working with adults should inquire about past childhood maltreatment.

Abstract
BACKGROUND Nonsuicidal self-injury (NSSI) is recognized as a public health concern for its association with unfavorable outcomes, including suicidal behavior. The aim of this study is to identify factors associated with NSSI among patients with nonpsychotic mental disorders (NPMD) and suicidal ideation in Russia. METHODS A retrospective cohort study was conducted in the Moscow Research and Clinical Center for Neuropsychiatry between November 2017 and May 2019. The sample was composed of consecutive patients with lifetime suicidal ideation (from the Self-Injurious Thoughts and Behavior Interview) seen in the center's psychiatric ward for NPMD. The patients were divided into two groups: those with and without lifetime NSSI. Sociodemographic variables, psychiatric diagnosis, family history of mental disorders, history of physical or sexual abuse, sexual behavior, ad-hoc psychiatric treatments, suicidal ideation, plans, and gestures or attempts were investigated. RESULTS Six thousand, two hundred and four consecutive patients were screened for suicidal ideation. Out of a total of 361 patients (87.3% females) with suicidal ideation, 217 (60.1%) reported NSSI. Variables independently associated with NSSI included age <25 years (OR 6.0, CI 2.5-14.7), dissatisfaction with the perceived parenting style (OR 3.3, CI 1.5-7.4), bullying (OR 2.6, CI 1.0-6.5), severe body modifications (OR 11.9, CI 1.1-134.3), experience with illicit drugs (OR 4.4, CI 1.9-10.3), and eating disorders (OR 4.9, CI 2.0-11.8). LIMITATIONS Retrospective design, referral population, single center study, and exclusion of psychotic patients. CONCLUSIONS NSSI is associated with age <25 years old, dissatisfaction with perceived parenting style, bullying, severe body modifications, lifetime experience of illicit drug-use, and lifetime eating disorders.HIGHLIGHTSNonsuicidal self-injury is a significant public health concern for its association with suicidal behavior.60.1% of Russian patients with non-psychotic mental disorders (NPMD) and suicidal ideation reported lifetime NSSI.NSSI in Russian patients with NPMD and suicidal ideation is associated with age less than 25 years, dissatisfaction with perceived parenting style, bullying, severe body modifications, lifetime experience of illicit drug use, and lifetime eating disorders.

Abstract
OBJECTIVE Nonsuicidal self-injury (NSSI) frequently co-occurs with eating disorders, especially bulimia nervosa (BN). Theoretical models and empirical evidence show many overlapping risk factors for the onset and maintenance of NSSI and BN. However, among those with BN, it remains unclear what distinguishes those who do versus do not engage in NSSI. The primary objective of the present study was to identify factors predicting NSSI among women with BN. Specifically, we tested four domains of borderline personality disorder as mediators between childhood trauma and NSSI. METHOD Using structural equation modeling we tested a parallel mediation model to predict NSSI among women with BN (N = 130). Childhood trauma (measured by the Childhood Trauma Questionnaire at baseline) was the independent variable. The four parallel mediators (measured at baseline via the Diagnostic Interview for Borderlines, Revised) were lifetime negative affect, impulsive actions, atypical cognitions (e.g., odd thinking, unusual perceptual experiences, quasi-psychotic thinking), and interpersonal problems. The dependent variable was instances of NSSI during a subsequent two-week ecological momentary assessment protocol. RESULTS Childhood trauma was significantly associated with all four mediators (all p values < .01), but only atypical cognitions predicted NSSI (p = .03). The indirect path from childhood trauma to NSSI, through atypical cognitions was significant (path coefficient = .001, SE < .001, p = .01). DISCUSSION Among women with BN, childhood trauma was associated with atypical cognitions, which in turn predicted NSSI. Atypical cognitions may be a mechanism for NSSI in this population.

Abstract
Psychodynamic psychotherapy has an important role in suicide prevention. The psychoanalytic study of suicide has taught us a great deal about the human experience and the process of suicidality. There is also much to be learned from other fields of study and from empirical research that can be integrated into psychoanalytic therapies. Central to the psychoanalytic approach to suicide has been understanding the patient's internal subjective experience of unbearable emotional or psychic pain and the urgent need for relief. Emotional pain can include intense affects such as shame, humiliation, self-hate, and rage. Factors that can increase vulnerability to suicidal states include problems with early attunement, dissociation and deficits in bodily love and protection, conscious and unconscious fantasy, and certain character traits and dynamics. Empirical research has confirmed many basic psychoanalytic concepts about suicide, including escape from unbearable pain as the primary driver of suicidal behavior, the role of dissociation in increasing risk of bodily attack, and the importance of unconscious processes. Further research into implicit processes and their role in the suicidal process holds potential to improve suicide risk assessment and to enhance psychotherapy by bringing otherwise inaccessible material into the treatment.

Abstract
Research shows that suicidal behavior is not a result of a single cause or single event, but instead is an interaction of facilitators. One potential facilitator that needs further exploration is dissociation. Dissociation has been consistently linked to suicidal behavior, and theories have posited that dissociation increases the possibility of a suicidal act via intensified disconnect from the body. However, these theories do not indicate whether dissociation is a facilitator of suicide risk by increasing suicidal ideation and attempt behaviors. Additionally, unique considerations of working with suicidal individuals have caused suicide research to lag behind research where laboratory manipulation is possible. Virtual Reality (VR) technology is potentially a useful new translational approach to studying suicide causes. Undergraduate students (n = 145) completed a dissociation induction task and then decided whether to engage in a virtual suicide option. Results showed that those who reported higher dissociation scores also reported higher suicide risk and indicated that certain facets of dissociation (i.e., depersonalization and derealization) significantly predicted engaging in virtual suicide. Results indicate that dissociation should be considered as a factor in the assessment and treatment of suicide risk. Limitations include that this used an uncommon suicide attempt method (i.e., jumping), and engaging in VR suicide is not the same as engaging in actual suicide or suicidal behaviors. However, VR may recreate certain sensations and situations one might experience when engaging in a suicide attempt and thus should be considered assessing and treating suicide risk.

Abstract
BACKGROUND Suicide attempt is the most predictive risk factor of suicide. Trauma - especially sexual abuse - is a risk factor for suicide attempt and suicide. A common reaction to sexual abuse is dissociation. Higher levels of dissociation are linked to self-harm, suicide ideation, and suicide attempt, but the role of dissociation in suicidal behavior is unclear. METHODS In this naturalistic study, ninety-seven acute psychiatric patients with suicidal ideation, of whom 32 had experienced sexual abuse, were included. Suicidal behaviour was assessed with The Columbia suicide history form (CSHF). The Brief trauma questionnaire (BTQ) was used to identify sexual abuse. Dissociative symptoms were assessed with Dissociative experiences scale (DES). RESULTS Patients who had experienced sexual abuse reported higher levels of dissociation and were younger at onset of suicidal thoughts, more likely to self-harm, and more likely to have attempted suicide; and they had made more suicide attempts. Mediation analysis found dissociative experiences to significantly mediate a substantive proportion of the relationship between sexual abuse and number of suicide attempts (indirect effects = 0.17, 95% CI = 0.05, 0.28, proportion mediated = 68%). Dissociative experiences significantly mediated the role of sexual abuse as a predictor of being in the patient group with more than four suicide attempts (indirect effects = 0.11, 95% CI = 0.02, 0.19, proportion mediated = 34%). CONCLUSION The results illustrate the importance of assessment and treatment of sexual abuse and trauma-related symptoms such as dissociation in suicide prevention. Dissociation can be a contributing factor to why some people act on their suicidal thoughts.

Abstract
BACKGROUND Dissociative disorder (DD) patients report high rates of self-injury. Previous studies have found dissociation and self-injury to be related to emotional distress. To the best of our knowledge, however, the link between emotion dysregulation and self-injury has not yet been examined within a DD population. OBJECTIVE The present study investigated relations between emotion dysregulation, dissociation, and self-injury in DD patients, and explored patterns of emotion dysregulation difficulties among DD patients with and without recent histories of self-injury. METHOD We utilized linear and logistic regressions and t-test statistical methods to examine data from 235 patient-clinician dyads enrolled in the TOP DD Network Study. RESULTS Analyses revealed emotion dysregulation was associated with heightened dissociative symptoms and greater endorsement of self-injury in the past six months. Further, patients with a history of self-injury in the past six months reported more severe emotion dysregulation and dissociation than those without recent self-injury. As a group, DD patients reported the greatest difficulty engaging in goal-directed activities when distressed, followed by lack of emotional awareness and nonacceptance of emotional experiences. DD patients demonstrated similar patterns of emotion dysregulation difficulties irrespective of recent self-injury status. CONCLUSIONS Results support recommendations to strengthen emotion regulation skills as a means to decrease symptoms of dissociation and self-injury in DD patients.

Abstract
Anxiety sensitivity (AS) and AS subfactors (physical, cognitive, and social) have been found to have robust associations with suicide risk. While the direct association between AS subfactors and suicide risk have been explored, little is known about how specific mechanisms, such as dissociation, might explain this relationship. This study aimed to run three analyses to examine the direct and indirect effects of suicidal thoughts and AS via dissociative symptoms. We predicted that dissociation would be a pathway through which AS physical concerns (ASPC) and AS cognitive concerns (ASCC) predicts suicidal ideation. Participants included 84 undergraduate students from a Southeastern University who were elevated on ASCC. Participants completed measures examining dissociative experiences, anxiety sensitivity, and current suicidal ideation. Results revealed that dissociation had a significant indirect effect with ASPC but not ASCC. The current preliminary study showed that ASCC had direct associations with suicide risk; however, those with lower levels of ASPC and dissociation may also be more likely to develop suicide risk. Future research should explore the possibility that the dissociation/ASPC and ASCC pathways are separate, but related, paths to suicidality.

Abstract
OBJECTIVE Several prognostic models of suicide risk have been published; however, few have been implemented in Japan using longitudinal cohort data. The aim of this study was to identify suicide risk factors for suicidal ideation in the Japanese population and to develop a machine-learning model to predict suicide risk in Japan. MATERIALS AND METHODS Data was obtained from Wave1 Time 1 (November 2016) and Time 2 (March 2017) of the National Survey for Stress and Health in Japan, were incorporated into a suicide risk prediction machine-learning model, trained using 65 items related to trauma and stress. The study included 3,090 and 2,163 survey respondents >18 years old at Time 1 and Time 2, respectively. The mean (standard deviation, SD) age was 44.9 (10.9) years at Time 1 and 46.0 (10.7) years at Time 2. We analyzed the participants with increased suicide risk at Time 2 survey. Model performance, including the area under the receiver operating characteristic curve (AUC), sensitivity, and specificity, were also analyzed. RESULTS The model showed a good performance (AUC = 0.830, 95% confidence interval = 0.795-0.866). Overall, the model achieved an accuracy of 78.8%, sensitivity of 75.4%, specificity of 80.4%, positive predictive value of 63.4%, and negative predictive value of 87.9%. The most important risk factor for suicide risk was the participants' Suicidal Ideation Attributes Scale score, followed by the Sheehan Disability Scale score, Patient Health Questionnaire-9 scores, Cross-Cutting Symptom Measure (CCSM-suicidal ideation domain, Dissociation Experience Scale score, history of self-harm, Generalized Anxiety Disorder-7 score, Post-Traumatic Stress Disorder check list-5 score, CCSM-dissociation domain, and Impact of Event Scale-Revised scores at Time 1. CONCLUSIONS This prognostic study suggests the ability to identify patients at a high risk of suicide using an online survey method. In addition to confirming several well-known risk factors of suicide, new risk measures related to trauma and trauma-related experiences were also identified, which may help guide future clinical assessments and early intervention approaches.

Abstract
BACKGROUND Cannabis is the most used recreational drug worldwide. Its use can increase the risk of developing psychotic disorders and exacerbate their course. However, the relationship between cannabis use and dissociative symptoms has been scarcely investigated. AIMS To examine differences in psychotic and dissociative symptoms, and in functioning in first-episode psychotic patients (FEPp) using cannabis compared with those not using cannabis. METHODS Between January 2014 and December 2019, seventy FEPp with cannabis use disorder (N = 35) and without it (N = 35) were recruited in psychiatric inpatient facilities in the Italian regions of Lazio and Piemonte. All subjects were assessed at FEP, after 4 and 8 months, using the Positive and Negative Syndrome Scale (PANSS), the Global Assessment of Functioning (GAF) scale and the Dissociative Experiences Scale - II (DES-II). Detailed information on the pattern of cannabis and other substance use were collected. RESULTS FEP using cannabis showed higher levels of positive symptomatology, dissociative experiences and worse functioning than their non-user counterpart, despite a comparable antipsychotic treatment. At an eight-month prospective evaluation, FEP using cannabis still showed higher levels of positive symptomatology and dissociation. Moreover, global functioning worsened over time in FEPp using cannabis, whereas it improved those not using it. DISCUSSION Our findings suggest that a greater degree of dissociation and positive symptoms at FEPp and their persistence over time may characterise cannabis-associated psychosis. Both these factors might explain the overall functioning worsening over time that we observed in the cannabis-user group compared to the functioning improvement in the non-user group.

Abstract
OBJECTIVE Childhood abuse survivors are at risk for suicidal ideation and suicide attempts. Research has indicated that posttraumatic stress disorder (PTSD) symptoms and dissociation are related to elevated suicidal ideation and behavior (SIB) among this population. At the same time, although the theoretical and clinical literature in the trauma field have suggested that survivors' pathological attachment to their perpetrators, known as identification with the aggressor, might explain SIB, this supposition has not been investigated to date. METHOD Filling this gap, this study explored the associations between identification with the aggressor, PTSD symptoms, dissociation, and SIB among 589 adult survivors of childhood abuse. RESULTS Identification with the aggressor, PTSD symptoms, and dissociation were related to elevated levels in suicidal ideation and behavior. Furthermore, profile type (namely, having high versus medium or low levels of identification with the aggressor, PTSD symptoms, and dissociation) was implicated in participants' SIB: Participants who adhered to a profile characterized by high levels of identification with the aggressor, PTSD symptoms, and dissociation had higher levels of suicide risk and suicidal ideation, as well as higher odds of reporting a history of suicide attempts, compared to participants who adhered to the other two profiles (i.e., characterized by medium or low levels of identification with the aggressor, PTSD symptoms, and dissociation). LIMITATIONS This study relied on convenience sampling and a cross-sectional design. CONCLUSIONS Identification with the aggressor might serve, alongside PTSD symptoms and dissociation, as a risk factor for suicidal ideation and behavior among childhood abuse survivors.

Abstract
To identify the demographic and clinical characteristics associated with access to Emergency Departments for Suicide Attempt in a cohort of patients with Gambling disorders. We used electronic health records of inpatient and outpatient services to identify individuals who received a diagnosis of gambling disorder (ICD-9 or ICD-10 codes) in the Metropolitan area of Bologna from 2009 to 2019. In this cohort we identified accesses to Emergency Departments for suicide attempt through cross-matching with electronic records. We calculated Crude Suicide Attempt Rates; we also included the demographic-clinical variables in a multivariate Poisson regression. We identified 692 patients with a diagnosis of gambling disorder and a total of 2733 Person Years. The Crude Suicide Attempt Rate per 1000 Person Years was 9.17 (95% CI 6.20-13.58), higher for females and much higher than the general population (incidence rate ratio = 93.72). The multivariate analysis showed a higher risk of suicide attempt in the year following the first contact with a clinical service, in patients younger than 45 years, with alcohol use disorders and personality disorders. This study evidenced a high risk of access to Emergency Departments for suicide attempt in individuals with a diagnosis of gambling disorder and highlighted important demographic and clinical factors that should be considered when evaluating suicide risk in this population.

Abstract
Dissociative disorders (DD) and conversion disorders (CD) are frequent in general and psychiatric populations. Some evidence suggest that the hypothalamic-pituitary axis (HPA) and autonomic nervous system (ANS) are dysregulated in both disorders. We carried out a systematic review of the literature to summarize the existing knowledge on the stress response, via HPA and/or ANS, in patients with DD, CD, or dissociative symptoms. We systematically searched Medline and Web of Science using the Medical Subject Headings related to stress axis, CD, DD, and dissociative symptoms following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results suggest that in participants without psychiatric history, high cortisol secretion is related to high dissociation scores. Conversely the stress system might be blunted in patients with post-traumatic stress disorder who develop dissociative symptoms. Stress response changes seem to be associated with the emergence and persistence of dissociative and conversion disorders. Hence, monitoring the stress response and examining closely the history of stress exposure in DD and CD should be encouraged in future larger studies.

Abstract
Non-suicidal self-injuries (NSSIs) have been identified as one of the most predictive factors of suicidal behaviours in adolescents. However, it remains unknown whether certain functions of NSSIs are associated with suicide risk, and what are the underlying mechanisms. Therefore, we aimed to investigate the association between functions of NSSIs and suicide risk in adolescents with conduct disorder (CD), which shares some common characteristics with NSSIs. Participants were 215 adolescents (155 females, 72.1%) with CD. Functions of NSSIs, depressive symptoms, the levels of impulsivity, anxiety, self-esteem and aggression were examined. There were 77 adolescents with lifetime history of NSSIs (35.8%). Among them, adolescents with lifetime history of suicide attempt were significantly more likely to report anti-dissociation and anti-suicide function of NSSIs. They had significantly higher levels of anxiety as well as significantly lower self-esteem. Higher lifetime number of NSSIs was associated with higher odds of reporting anti-dissociation and anti-suicide functions. Moreover, these two functions fully mediated the association between lifetime number of NSSIs and suicide risk after co-varying for depressive and anxiety symptoms as well as self-esteem. The present findings indicate that anti-suicide and anti-dissociation functions of NSSIs might be crucial predictors of suicide risk in adolescents with CD.

Abstract
This study aimed to examine associations between suicide attempts (SA), suicidal ideation (SI), depression, dissociative symptoms, emotional abuse, physical abuse and sexual abuse, and to explore predictors of SA and SI, as well as possible mediating factors. We also aimed to examine support for a dissociative depression subgroup. Participating in this study were 342 adults, of these were 138 respondents with a diagnosis of depression (DG), and 204 respondents comprising a community sample (CS). Respondents completed the Center for Epidemiologic Studies Depression Scale - Revised (CESD-R), Childhood Trauma Questionnaire - Short Form (CTQ-SF), and Dissociative Experience Scale (DES). All but two (DES-Absorption and DES - Depersonalization/Derealization) of the study variable mean scores were higher in the DG than in the CS group. Regression analysis showed that SA was predicted by sexual abuse and DES-Amnesia in the CS group. Structural equation modeling revealed that in both groups the types of abuse were reciprocally correlated, emotional abuse was linked to dissociation, which in turn was related to depression, which is turn was predictive of suicide ideation. Depression had a full mediating effect between dissociation and suicide ideation in the CS, and a partial mediating effect in the DG. Sexual abuse had a direct effect upon depression and suicide ideation in the DG. Cluster analysis provided support for a dissociative depression subtype.

Abstract
In patients with eating disorders (EDs), elevated dissociation may increase the risk of suicide. Bodily related disturbances, depression, and anxiety may intervene in the association between dissociation and suicidality. In this study we aimed to examine the influence of bodily related disturbances, depression, anxiety, severity of ED symptoms, body mass index (BMI), and type and duration of the ED on the relationship between elevated dissociation and elevated suicidality. The study included 172 inpatients: 65 with anorexia nervosa restricting type, 60 with anorexia nervosa binge/purge type, and 37 with bulimia nervosa. Participants were assessed using self-rating questionnaires for dissociation, suicidality, bodily related parameters, and severity of ED symptomatology, depression, and anxiety. We found that dissociation and suicidality were directly associated. In addition, depression and anxiety moderated the mediating role of body image parameters in the association between increased dissociation and increased suicidality. Thus, only in inpatients with high depression and anxiety, i.e., above the median range, body image disturbances were found to mediate the association between dissociation and suicidality. ED-related parameters did not moderate these relationships. Our study demonstrates that in inpatients with EDs, increased dissociation may be significantly associated with increased suicidality, both directly and via the intervening influence of body image, depression, and anxiety.

Abstract
Fears of pain, injury, and death may represent key barriers to acting on suicidal thoughts. Dissociation, which involves a disconnection from one's body, may reduce fears and sensations of pain associated with harming the body, in turn facilitating suicide attempts. This study examined whether dissociation differentiated individuals with a history of suicide attempts from those with a history of suicide ideation, and investigated whether other relevant constructs explain this relationship. Sample 1 included 754 undergraduates (Mage = 21, 79% female) who completed a battery of self-report measures. Sample 2 included 247 undergraduates (Mage = 19, 74% female) who completed a self-report measure of dissociation, a clinical interview regarding suicide history, and four counterbalanced behavioral pain tolerance tasks. In both samples, dissociation was elevated in lifetime attempters compared to ideators (d = 0.28; d = 0.46; ps = 0.01) and slightly elevated in lifetime ideators compared to nonsuicidal individuals (d = 0.19, p = .02; d = 0.24, p = .47), though this effect was non-significant in the latter sample. In Sample 1, dissociation no longer differentiated attempters from ideators after controlling for clinical covariates. In Sample 2, dissociation was unrelated to behavioral pain tolerance tasks, and these tasks did not account for the association between dissociation and attempts. Overall, dissociation differentiated individuals with a history of suicide attempts from those with ideation alone in both samples. Pain tolerance did not explain this association; instead, it is possible that the relationship of dissociation to suicide attempts is due to "third variables" associated with both phenomena, such as symptoms of borderline personality disorder or posttraumatic stress disorder.

Neuroimaging Studies of Nonsuicidal Self-Injury in Youth: A Systematic Review. Life (Basel) 2021; 11:life11080729. [PMID: 34440473 PMCID: PMC8399885 DOI: 10.3390/life11080729] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 07/16/2021] [Accepted: 07/19/2021] [Indexed: 01/14/2023] Open
Abstract
Nonsuicidal self-injury (NSSI) is prevalent and affects mainly the youth population. It is prospectively associated with suicide attempts, making it a target for suicide prevention. Recently, several studies have investigated neural pathways of NSSI using neuroimaging. However, there is a lack of systematized appraisal of these findings. This systematic review aims to identify and summarize the main neuroimaging findings of NSSI in youth. We followed PRISMA statement guidelines and searched MEDLINE, APA PsycInfo, and Google Scholar databases for neuroimaging studies, irrespective of imaging modality, specifically investigating NSSI in samples with a mean age of up to 25 years old. Quality assessment was made using the Newcastle–Ottawa and Joanna Briggs Institute scales. The initial search retrieved 3030 articles; 21 met inclusion criteria, with a total of 938 subjects. Eighteen studies employed functional neuroimaging techniques such as resting-state and task-based fMRI (emotional, interpersonal exposure/social exclusion, pain, reward, and cognitive processing paradigms). Three studies reported on structural MRI. An association of NSSI behavior and altered emotional processing in cortico-limbic neurocircuitry was commonly reported. Additionally, alterations in potential circuits involving pain, reward, interpersonal, self-processing, and executive function control processes were identified. NSSI has complex and diverse neural underpinnings. Future longitudinal studies are needed to understand its developmental aspects better.

Abstract
Current evidence suggests a high prevalence of childhood trauma (CT) among adult patients diagnosed with schizophrenia spectrum disorders. Exposure to CT might lead to clinical differences eventually observed in these patients. We present a cross-sectional study with 54 patients with schizophrenia spectrum disorder (schizophrenia and schizoaffective disorder). We obtained sociodemographic data, as well as data on CT, dissociation, suicide history, and intensity of positive and negative psychotic symptoms. More than 75% of the patients reported a history of CT. We observed a link between CT and suicidal behavior. Patients showed high rates of dissociation. Dissociative experiences were related to CT, both in terms of intensity of trauma and number of traumas experienced. All CT forms except emotional neglect showed direct correlations with dissociative experiences. We found no correlation between intensity of CT and intensity of positive psychotic symptoms, yet we observed a moderate inverse correlation with negative psychotic symptoms.

Front Psychiatry 2021; 12:732843. [PMID: 34759848 PMCID: PMC8572831 DOI: 10.3389/fpsyt.2021.732843] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 09/27/2021] [Indexed: 11/21/2022] Open
Abstract
Background: Dissociative symptoms are under recognized and scarcely studied by clinicians and researchers in patients with bipolar disorder (BD). We examined the relationship between dissociative symptoms and the psychotic features in patients with BD and assessed clinical and socio-demographic characteristics more frequently associated with dissociative symptoms and treatment response. Methods: Participants were 100 adult outpatients with BD. They were screened with semi-structured interview to collect socio-demographic and clinical characteristics; the Dissociative Experiences Scale-II (DES-II) and the ALDA scale were used to assess dissociative psychopathologies and response to treatment with mood stabilizers, respectively. Results: DES score (mean 31.7 ± 21.7) correlated with clinical variables, BD features, and course of illness. Psychotic symptoms, mixed features, and previous suicide attempts significantly predicted DES score [F (3, 47) = 39.880, p < 0.001, R 2 corrected = 0.713]. Dissociative symptoms were inversely correlated with poor response to treatment (r = -0.593; p < 0.001). Limitations: Cross-sectional design with a small sample and backward clinical assessment of psychotic symptoms. Conclusions: Dissociative phenomena are closely related to the presence of psychotic symptoms, mixed features, and previous suicide attempts in BD, especially in BD-I. Given the close association between dissociative and psychotic symptoms, this association could represent a diagnostic indicator of BD-I that may guide the clinician to plan the most appropriate treatment.

[PMID: 33446299 PMCID: PMC8293624 DOI: 10.1017/s1352465820000958] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Revised: 09/17/2020] [Accepted: 11/20/2020] [Indexed: 11/20/2022]
Abstract
BACKGROUND Catastrophic cognitive appraisals, similar to those in anxiety disorders, are implicated in depersonalisation, a form of dissociation. No scales exist to measure appraisals of dissociative experiences. Dissociation is common in psychosis. Misinterpretations of dissociative experiences may maintain psychotic symptoms. Therefore, assessing appraisals in this context may be valuable. AIMS The primary aim was to develop a measure of key appraisals of dissociation in psychosis. Secondary aims were to test the relationship between appraisals and psychotic experiences (paranoia and hallucinations), and determine whether appraisals explain additional variance in psychotic symptoms above dissociative symptoms. METHOD Fifty items were generated from transcripts of interviews with patients. The measure was developed and psychometrically validated via factor analysis of data from 9902 general population participants and 1026 patients with psychosis. Convergent validity, test-re-test reliability, and internal reliability were assessed. Regression analyses tested relationships with psychotic symptoms. RESULTS A 13-item single-factor measure was developed. Factor analysis indicated good model fit [χ2(65) = 247.173, comparative fit index (CFI) = 0.960, root mean square error of approximation (RMSEA) = 0.052]. The scale had good convergent validity with a rumination (non-clinical: r = 0.71; clinical: r = 0.73) and dissociation measure (r = 0.81; r = 0.80), high internal consistency (α = 0.93; α = 0.93), and excellent 1-week test-re-test reliability [intraclass correlation (ICC) = 0.90]. It explained variance in psychotic symptoms (paranoia: 36.4%; hallucinations: 35.0%), including additional variance compared with dissociation alone (paranoia: 5.3%; hallucinations: 2.3%). CONCLUSIONS The Cognitive Appraisals of Dissociation in Psychosis (CAD-P) measure is a psychometrically robust scale identifying appraisals of dissociative experiences in psychosis and is associated with the presence of psychotic experiences. It is likely to prove useful for clinical assessment and research.

Abstract
OBJECTIVE The COVID-19 pandemic affected today more than 3,000,000 worldwide, and more than half of humanity has been placed in quarantine. The scientific community and the political authorities fear an epidemic of suicide secondary to this crisis. The aim of this review is to analyze the impact of the COVID-19 pandemic on the dimensions of the suicidal process and its interaction with the various risk factors. We also propose innovative strategies to manage suicidal behavior in the context of pandemic. METHODS We carried out a narrative review of international publications dealing with major pandemics (COVID-19, SARS) and their influence on suicidal vulnerability. RESULTS Many factors are likely to increase the emergence of suicidal ideation and suicide attempts during this crisis. Social distancing and quarantine could increase the feeling of disconnection and the perception of social pain in vulnerable individuals. Some populations at high suicidal risk could be further impacted by the current pandemic: the elderly, medical staff and individuals exposed to economic insecurity. Several innovative tools adapted to the constraints of social distancing and quarantine may prevent suicide risk: e-health, VigilanS, buddhist-derived practices and art engagement. CONCLUSIONS This unprecedented crisis may interact with certain dimensions of the suicidal process. However, it is time to innovate. Several suicide prevention tools all have their place in new modes of care and should be tested on a large scale.

Abstract
BACKGROUND Self-injurious behaviours (SIB) occur frequently in individuals with borderline personality disorder (BPD). While multiple factors may explain the association between SIB and BPD, studies in adults have pointed to dissociation as factor worth considering. However, this relationship has not been examined in adolescents. AIMS The current study investigated the role of dissociation as a potential moderator between borderline features and SIB, with the expectation that this association would be stronger in the presence of dissociation. METHODS One hundred forty-four adolescent inpatients were compared on measures of BPD, non-suicidal self-injury (NSSI) and suicidal behaviour. The relationships between borderline features and self-injury outcomes were evaluated using linear and logistic regression with dissociation as a moderator. RESULTS Borderline features and dissociation were found to be significantly associated with history of NSSI, history of suicide attempt, suicidal ideation (SI) intensity and SI severity. However, dissociation was a significant moderator only in the relationship between borderline features and SI intensity. CONCLUSION Higher levels of dissociation were associated with more engagement with suicidal thoughts but did not necessarily contribute to SIB. Further research into differential patterns of association of self-injury in patients with BPD may investigate other models where dissociation may more strongly factor into outcomes. © 2020 John Wiley & Sons, Ltd.
