A cross-national investigation of psychosis-like experiences in five European countries included in the E-CLECTIC study: Psychometric challenges in studying their measurement. Psychiatry Res 2024; 339:116072. [PMID: 39002501 DOI: 10.1016/j.psychres.2024.116072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 06/24/2024] [Accepted: 06/29/2024] [Indexed: 07/15/2024]
Abstract
BACKGROUND Psychotic-like experiences (PLEs) are subtle, subclinical perturbations of perceptions and thoughts and are common in the general population. Their characterisation and unidimensionality are still debated. METHODS This study was conducted by the Electronic-halluCinations-Like Experiences Cross-culTural International Consortium (E-CLECTIC) and aimed at measuring the Community Assessment of Psychic Experiences (CAPE) factorial structure across five European countries (Belgium; Czech Republic, Germany; Greece, and Spain) and testing the adequacy of the unidimensional polytomous Rasch model of the tool via Partial Credit Model (PCM) of the CAPE to detect people with a high risk for developing psychosis. RESULTS The sample included 1461 participants from the general population. The factorial analysis confirmed the best fit for the bifactor implementation of the three-factor model, including the positive, negative and depressive dimensions and a general factor. Moreover, the unidimensional polytomous Rasch analysis confirmed that CAPE responses reflected one underlying psychosis proneness. CONCLUSIONS The study proved that the CAPE measures a single latent dimension of psychosis-proneness. The CAPE might help locate and estimate psychosis risk and can be used as a screening tool in primary care settings/education settings.

Eur Child Adolesc Psychiatry 2024; 33:1977-1985. [PMID: 37740799 PMCID: PMC11211151 DOI: 10.1007/s00787-023-02299-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 09/08/2023] [Indexed: 09/25/2023]
Abstract
Research in adolescents suggests associations between psychotic-like experiences (PLEs) and self-injurious thoughts and behaviors (SITBs), but insights into their temporal relationship, which may inform prediction, have been limited. Psychological distress (PD; symptoms of depression and anxiety) has been related to both PLEs and SITBs, and may modulate this relationship. Given that PLEs have been linked to the development of several mental disorders, and the relationships between SITBs and suicide, it is important to better understand their relationship. The present study sought to investigate these factors using a longitudinal school-based design. Adolescents (n = 1685, ages 12-18) completed annual self-report assessments (6 time points) on PLEs, SITBs (suicidal ideation (SI) and self-harm (SH)), as well as PD. The longitudinal associations between PLEs and SITBs were analyzed, employing two cross-lagged panel models (CLPMs), with and without adjustment for PD. Unadjusted CLPMs revealed significant bidirectional temporal associations between PLEs and SITBs (both SI and SH), suggesting that PLEs both predicted and were predicted by SITBs. When adjusting for PD, the effect of SI on PLEs remained significant, but not PLEs on SI; bidirectional associations between PLEs and SH also remained significant. A bidirectional longitudinal relationship where both PLEs and SITBs can precede (and perhaps predict) each other was suggested in adolescents. PD may play a particular role in situations where PLEs are followed by SI. Heightened awareness about relationships between these phenotypes may be an important step toward facilitating timely interventions for both mental disorders and suicide.

Abstract
OBJECTIVES Flexibility in self-regulation has emerged as an important component of mental health. Previous findings found that deficits in two components of regulatory flexibility were linked cross-sectionally to psychosis-proneness. We aimed to replicate and extend these findings longitudinally. METHODS We measured psychosis-proneness and components of emotion regulation flexibility (i.e. context sensitivity, repertoire and feedback) at two time points with three months in between. RESULTS Two flexibility components predicted psychotic-like experiences. The ability to detect the absence of contextual cues was implicated in both positive and negative dimensions but through opposite pathways. Expressive suppression ability-a subcomponent of repertoire-predicted positive symptoms. None of the flexibility components predicted distress related to the symptoms. CONCLUSIONS The current study provides further evidence on the implication of emotion regulation flexibility in the longer-term maintenance of psychotic-like experiences. Future studies can advance this work further by evaluating possible bidirectional relationships between psychotic-like experiences and deficits in emotion regulation flexibility.

Abstract
BACKGROUND Several studies have reported that psychotic-like experiences are associated with low levels of resilience and increased suicide risk. However, it remains unknown as to whether resilience mediates or moderates the association between psychotic-like experiences and suicide risk. Therefore, in this study, we aimed to explore the moderating and mediating effect of resilience in the association between psychotic-like experiences and suicide risk. METHODS A total of 1100 non-clinical, young adults (aged 18 - 35 years) with a negative history of psychiatric treatment were enrolled. Participants were recruited by the snowball sampling methodology through advertisements posted in the online platform. They were followed-up for about 7 months. Variables of interest were recorded using self-reports. Psychopathological assessment was conducted using the Prodromal Questionnaire-16, the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7, the Traumatic Experience Checklist, the Childhood Experience of Care and Abuse Questionnaire, the Cannabis Problems Questionnaire, the Connor-Davidson Resilience Scale-10, and the Mini-International Neuropsychiatric Interview. The STROBE statement guidelines were followed. RESULTS The moderation analysis revealed that higher levels of psychotic-like experiences and related distress at baseline were associated with significantly higher suicide risk at the follow-up after adjustment for baseline sociodemographic characteristics, depressive and anxiety symptoms, a history of childhood trauma, and problematic cannabis use. The interaction between follow-up resilience and distress related to baseline psychotic-like experiences was significantly and negatively associated with suicide risk at the follow-up. Specifically, the correlation between the level of distress related to psychotic-like experiences and suicide risk was significant and positive only in participants with lower levels of resilience. This interaction did not reach statistical significance for the baseline level of psychotic-like experiences. No significant mediating effect of the follow-up resilience level in the association between baseline psychotic-like experiences and the follow-up suicide risk was found. CONCLUSIONS Findings from the present study indicate that resilience might protect against suicide risk in people with psychotic-like experiences. These findings could be applied in the formulation of early intervention strategies aimed at mitigating the risk of suicide. Future studies need to explore the effects of interventions targeting resilience for individuals with psychotic-like experiences.

Abstract
BACKGROUND AND HYPOTHESIS Suicide is a leading cause of death in youth and is often preceded by suicidal ideation (SI) and non-suicidal self-injury (NSSI). Identifying early markers of risk for SI and NSSI could improve timely identification of at-risk individuals. STUDY DESIGN Children (mean age 11.9, SD 0.2) at familial high risk of schizophrenia (N = 171), or bipolar disorder (N = 104), and controls (N = 174) were assessed for psychotic experiences (PE), SI, NSSI, and Axis I mental disorders in face-to-face interviews in early and middle childhood (age 7 and 11). STUDY RESULTS Having 2 types of early childhood PE predicted middle childhood SI after accounting for previous SI, NSSI, and mental disorders (OR 2.8, 95% CI 1.1-6.9; P = .03). Two PE predicted NSSI (OR 3.0, 95% CI 1.2-7.7; P = .02) in excess of previous SI, NSSI, mental disorders, and familial risk. Persistent and incident PE predicted SI (OR 3.2, 95% CI, 1.1-8.8; P = .03; OR 3.8, 95% CI, 1.3-11.5; P = .02) in the fully adjusted model. Nineteen percent of children with persistent PE reported middle childhood SI vs 3.8% of those who never reported PE. In children with early childhood mental disorders, those who reported 2 PE had 4.4-fold increased odds of later SI (95% CI, 1.2-16.7; P = .03) after adjustments. PE were nondifferentially associated with outcomes across familial risk groups. CONCLUSIONS Early childhood PE index elevated risk for subsequent SI and NSSI beyond what can be attributed to presence of mental disorders. Mental health screenings and clinical assessments should include early childhood PE.

Abstract
This study investigates the relationship between psychotic symptoms and suicide attempts in young first-episode, drug-naive Chinese Han outpatients diagnosed with Major Depressive Disorder (MDD). The prevalence of Psychotic Major Depressive Disorder (PMD) was found to be 8.3% among the enrolled MDD patients. The study assessed 1289 participants using various scales to evaluate the severity of clinical symptoms, including the CGI-S, the HAMD, the HAMA, and the PANSS positive subscale. Additionally, thyroid hormone and glucolipid metabolism indicators were examined. The findings indicate that among patients with PMD, 41.12% had recent suicide attempts, while 6.54% had previous suicide attempts. Patients who recently attempted suicide exhibited higher scores on the HAMA and CGI scales, along with elevated serum levels of Thyroid-Stimulating Hormone (TSH) and total cholesterol (TC), as well as higher systolic and diastolic blood pressure. Notably, TSH levels independently correlated with recent suicide attempts in PMD patients, with an impressive area under the receiver operating characteristic curve (AUROC) of 0.923. Furthermore, the subgroup of patients with previous suicide attempts displayed longer illness duration and higher HAMD scores. Duration of illness and HAMD were found to be independently associated with previous suicide attempts among PMD patients, with a combined predictive effect showing a robust AUROC of 0.910. In conclusion, this study highlights the significant prevalence of recent and previous suicide attempts among young Chinese Han outpatients with PMD. The identification of risk factors, especially the link between TSH levels and recent suicide attempts, offers valuable insights for clinicians to develop targeted interventions and preventive strategies for this vulnerable patient population.

Abstract
BACKGROUND AND HYPOTHESIS Psychotic experiences (PEs) are associated with increased risk for mental disorders, in particular persistent PEs. PEs therefore might be useful within intervention research. We sought to systematically determine the incidence and persistence of PEs in the general population. STUDY DESIGN A double-blind search of databases (Embase, Pubmed PMC, Psychinfo, Medline, and Web of Science) from inception to January 2023 and data extraction, were conducted. Study quality was assessed using the NIH assessment tool. Random effects models were conducted to calculate pooled incidence rate per person-year and proportion of persistent PEs per year. Age and study design were all examined using subgroup analyses. Demographic, risk factors, and outcomes for incidence and persistence of PEs were reported in a narrative synthesis. STUDY RESULTS Using a double-blind screening method for abstract (k = 5763) and full text (k = 250) were screened. In total 91 samples from 71 studies were included, of which 39 were included in a meta-analysis (incidence: k = 17, n = 56 089; persistence: k = 22, n = 81 847). Incidence rate was 0.023 per person-year (95% CI [0.0129;0.0322]). That is, for every 100 people, 2 reported first onset PEs in a year. This was highest in adolescence at 5 per 100(13-17 years). The pooled persistence rate for PEs was 31.0% (95% CI [26.65,35.35]) This was highest in adolescence at 35.8%. Cannabis was particularly associated with incidence of PEs, and persistence of PEs were associated with multiple mental disorders. CONCLUSIONS Each year incidence of PEs is 2 of every 100 people, and persists each year in 31% of cases, this risk is highest in adolescents.

Psychotic experiences, suicidality and non-suicidal self-injury in adolescents: Independent findings from two cohorts. Schizophr Res 2023; 257:50-57.

Abstract
BACKGROUND Prior studies have shown that psychotic experiences are prospectively associated with an increased risk of suicidality. However, it is unclear whether this association is causal or arises from shared risk factors. Furthermore, little is known about the association between psychotic experiences and non-suicidal self-injury (NSSI). METHODS We used data from two independent samples of young adolescents, which we analyzed separately. In a population-based cohort, data on hallucinatory experiences and suicidality were collected at ages 10 and 14 years (N = 3435). In a cross-sectional study of a population oversampled for elevated psychopathology levels, psychotic experiences, suicidality, and NSSI were assessed at age 15 years (N = 910). Analyses were adjusted for sociodemographic covariates, maternal psychopathology, intelligence, childhood adversity, and mental health problems. RESULTS Psychotic experiences were prospectively associated with an increased risk of suicidality, even when considering self-harm ideation at baseline. Furthermore, persistent and incident, but not remittent, patterns of psychotic experiences were related to an increased burden of suicidality. Self-harm ideation was also prospectively associated with the risk for psychotic experiences, although of smaller magnitude and only by self-report. Among at-risk adolescents, psychotic experiences were cross-sectionally associated with a greater burden of suicidality and a higher frequency of NSSI events, with more extensive tissue damage. CONCLUSION Psychotic experiences are longitudinally associated with suicidality beyond the effects of shared risk factors. We also found modest support for reverse temporality, which warrants further investigation. Overall, our findings highlight the importance of assessing psychotic experiences as an index of risk for suicidality and NSSI.

Abstract
BACKGROUND Non-suicidal self-injury (NSSI) and suicide are a serious health concern in young people. Remarkable progress has been made in understanding the correlates and risk factors for suicidality. However, it remains unclear the complex interplay between different factors and which factors are most saliently associated with NSSI and suicide risk and should be targeted for interventions. METHODS This study utilized network analysis to examine the interrelationship between NSSI, suicide and a variety of psychological (e.g., depression, psychotic-like experiences) and psychosocial (e.g., childhood maltreatment, family dysfunction, being bullied and social support) correlates in a sample of Chinese first year college students (n = 2328). RESULTS The severity of depressive symptoms was the only factor connected to both NSSI and suicide. Other psychiatric factors like psychotic experiences could only act in an indirect way via the bridging effect of depression. Emotional abuse, compared with other forms of childhood adversities, was found to be the most influential maltreatment form associated with suicidal ideation and attempts. Finally, social support showed the potential to lower the risk of self-injury and suicide in young people. LIMITATIONS Only a subset of risk and resilience factors of NSSI and suicide were included. Causal inference was impossible due to the cross-sectional design. CONCLUSIONS Our findings highlighted the importance of identifying risk groups with mental illnesses or negative childhood events, and providing additional support during the key time of transitioning into higher education.

Unraveling the complexity of associations between a history of childhood trauma, psychotic-like experiences, depression and non-suicidal self-injury: A network analysis.

Abstract
BACKGROUND Several studies have reported the association of psychotic-like experiences (PLEs) with non-suicidal self-injury (NSSI). It has been hypothesized that both constructs might share overlapping backgrounds. This study aimed to investigate the relationships between childhood trauma, depression, PLEs and lifetime characteristics of NSSI. METHODS Participants included individuals aged 18-35 years who had a negative history of psychiatric treatment. They were surveyed through the computer-assisted web interview. A network analysis was performed. RESULTS A total of 4203 non-clinical adults (63.8 % females) were enrolled. The characteristics of NSSI and a history of childhood sexual abuse were the most central nodes in the network. A history of childhood sexual abuse was the only category of childhood trauma that was directly connected to the characteristics of NSSI (i.e., longer lifetime duration of NSSI). The shortest pathways from other categories of childhood trauma (emotional abuse, emotional neglect and bullying) were connected to the lifetime characteristics through the effects of sexual abuse. However, other pathways were also possible and converged on nodes representing persecutory thoughts, déjàvu experiences, psychomotor retardation/agitation and suicidal ideation. These psychopathological symptoms were the only nodes directly connected to the characteristics of NSSI (i.e., lifetime duration and a history of severe NSSI). LIMITATIONS The main limitations include the use of a non-clinical sample and cross-sectional design. CONCLUSIONS Our findings do not support the hypothesis that PLEs and NSSI might be associated due to shared correlates. In other words, the associations of childhood trauma and PLEs with NSSI might be independent.

Abstract
BACKGROUND AND HYPOTHESES A wealth of evidence suggests that adolescent psychotic experiences (PEs), and especially auditory hallucinations (AHs), are associated with an increased risk for self-injurious behavior (SIB). However, the directionality and specificity of this association are not well understood, and there are no published studies investigating within-person effects over time. The present study aimed to test whether AHs and SIB prospectively increase reciprocal risk at the individual level during early-to-middle adolescence. STUDY DESIGN Three waves (12y, 14y, and 16y) of self-reported AHs and SIB data from a large Tokyo-based adolescent birth cohort (N = 2825) were used. Random Intercept Cross-Lagged Panel Model (RI-CLPM) analysis was conducted to test the within-person prospective associations between AHs and SIB. STUDY RESULTS At the within-person level, AHs were associated with subsequent SIB over the observation period (12y-14y: β = .118, P < .001; 14-16y: β = .086, P = .012). The reverse SIB->AHs relationship was non-significant at 12-14y (β = .047, P = .112) but emerged from 14y to 16y as the primary direction of influence (β = .243, P < .001). Incorporating depression as a time-varying covariate did not meaningfully alter model estimates. CONCLUSIONS A complex bi-directional pattern of relationships was observed between AHs and SIB over the measurement period, and these relationships were independent of depressive symptoms. Adolescent AHs may be both a predictor of later SIB and also a manifestation of SIB-induced psychological distress.

Exploring the relation between psychosis-like experiences and suicidal ideation, plans, and attempts among college students in the United States. Early Interv Psychiatry 2023; 17:272-280. [PMID: 35712796 DOI: 10.1111/eip.13325] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Revised: 03/27/2022] [Accepted: 05/29/2022] [Indexed: 11/25/2022]
Abstract
AIM The suicide rate among college students is particularly high, with evidence that psychosis-like experiences (PLEs) put these individuals at greater risk. The current study explored whether there are differential relations between four subtypes of PLEs and three suicide outcomes. METHODS We analysed a large sample of college students from the Fall semester cohort of the 2020 Healthy Minds Study (HMS) (weighted N = 36727). PLEs and suicide outcomes were assessed using binary variables from the World Health Organization Composite International Diagnostic Interview. RESULTS Findings revealed that reporting any of the subtypes of PLEs was associated with greater odds of suicidal ideation (SI), a suicide plan (SP) and a suicide attempt (SA) (signficant a ORs ranging from 1.30 to 3.30). For college students who endorsed SI or a SP in the past year, experiencing delusional mood (aOR [95% CI] = 1.30 [1.02-1.65]), suspiciousness (aOR [95% CI] = 1.31 [1.00-1.71]) and hallucinatory experiences (aOR [95% CI] = 2.76 [2.05-3.71]) in their lifetime increased their odds of reporting a SA in the past year. There was also evidence of a dose-dependent relation between the number of PLEs endorsed and all three suicide outcomes. CONCLUSIONS Certain subtypes of PLEs including delusional mood, suspiciousness and hallucinatory experiences may contribute to an elevated risk of suicide outcomes in college students. Moreover, the odds of reporting suicide outcomes were greater for individuals who endorsed a greater number of PLEs. It may be helpful to assess for indicated subtypes when determining suicide risk among college students and to be particularly mindful of those who report three or more PLEs.

Abstract
The present study followed the newly hypothesized "suicidal drive for psychosis" suggesting that psychosis may be consequential to suicidal ideation (SI) and behavior and attempted to explain parts of the pathway between these variables. To this end, we aimed to test whether problematic smartphone use (PSU) has an indirect mediating effect in the cross-sectional relationship between SI and positive psychotic experiences (PEs). Lebanese community young adults (N=4158; 64.4% females; mean age 21.91±3.79) have been invited to participate to a cross-sectional, web-based study in the period from June to September 2022. After adjusting for potential confounders (i.e., the living situation, marital status, household crowding index, economic pressure, cannabis use, other drugs use, and past history of mental illness other than psychosis), we found that higher levels of suicidal ideation was significantly associated with greater PSU, which was also positively and significantly associated with more positive PEs. Finally, greater suicidal ideation was significantly and directly associated with more positive PEs. Our findings suggest that SPU may be regarded as a potential target for prevention and intervention in psychosis. Clinicians, educators, and school administrators ought to give greater attention to PSU among vulnerable young people who present with SI.

Abstract
AIM Premorbid cognitive impairments are observed prior to the onset of schizophrenia. Catechol-O-methyltransferase (COMT) rs4680 is associated with psychosis and plays a crucial role in the development of the executive function. In addition, genetic COMT variations and gender affect its enzymatic activity. Therefore, the aim of this study was to evaluate the impact of COMT rs4680 on the relationship between executive dysfunction and psychotic-like experiences (PLEs) in college students, with the additional investigation of the gender difference. METHODS A total of 463 students provided biological samples for DNA analysis and the COMT gene rs4680 polymorphism was discriminated by the improved multiplex ligase detection reaction method. They also completed the Prodromal Questionnaire and the Dysexecutive Questionnaire. RESULTS Executive dysfunction significantly predicted positive PLEs in the total, male and female population (β = 0.515, 0.508 and 0.512, p < 0.001). The results of moderated analysis revealed that COMT rs4680 recessive genetic model ('AA genotype' versus 'G carrier') moderated the relationship between executive dysfunction and psychotic-like experience in the total and females (p = 0.002 and p <0.001, respectively), but not in males. CONCLUSION These findings revealed a female-specific effect of COMT rs4680 on the relationship between executive dysfunction and PLEs in young adults.

Attributes of auditory hallucinations that are associated with self-harm: A prospective cohort study. Schizophr Res 2023; 251:30-36.

Abstract
There is a well-documented epidemiological association between auditory hallucinations and self-harm in the general population. However, there has been limited research examining specific characteristics of auditory hallucinations (e.g., type, source, or context of voices) as correlates of self-harm. We used prospective data from the Tokyo Teen Cohort to explore whether characteristics of voices reported at age 14 were differentially associated with self-harm behaviors at ages 14 and 16. Among respondents with auditory hallucinations, respondents who experienced voices that "said something bad" about them or commented on their thoughts and actions were most likely to report concurrent self-harm, whereas positive or praising voices were protective. Negative voices continued to predict self-harm two years later, at age 16, even with adjustment for self-harm at age 14. The age of the voices, source of the voices, and context (e.g., falling asleep or while sick) was not associated with likelihood of reporting concurrent or subsequent self-harm behaviors. Assessing for negative voices in particular, rather than auditory hallucinations or psychotic experiences more broadly, may provide a more specific indicator of risk for self-harm among adolescents. The real-world utility of these epidemiological findings should be further examined in clinical settings.

Abstract
AIM This study investigated the influence of childhood adversity, such as peer bullying and socioeconomic status, on the suicidal behaviour of left-behind Chinese adolescents to determine whether psychotic-like experiences (PLEs) mediated the associations between these childhood adversities and suicidality; suicidal ideation (serious thoughts about taking one's own life), suicide plans, and suicide attempts. METHODS A representative group of rural adolescents (n = 3346) was recruited from 16 rural high schools in China. Suicidality was assessed using the suicide module from the Mini International Neuropsychiatric Interview Kid. Participants also completed questionnaires on bullying, socioeconomic status, left-behind characteristics, and PLEs. Structural equation modelling was then employed to explore the relationships between these variables. RESULTS Peer bullying, poverty, and left-behind status were all found to significantly increase adolescent suicide risk, the relationships between which were mediated by PLEs. Peer bullying was found to play the most significant role in the PLEs and suicidality, with the risk of suicide increasing with the length of time a child had been left behind. CONCLUSION Adverse life events can lead to a high risk of PLEs, which in turn can increase the risk of suicide. These results could assist in identifying individuals at risk of suicidality and the design of appropriate interventions. The results also highlighted the role PLEs play in suicidality and highlighted the need for further research in this area.

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
Childhood psychotic-like experiences (PLEs) are associated with a range of impairments; a subset of children experiencing PLEs will develop psychiatric disorders, including psychotic disorders. A potential distinguishing factor between benign PLEs versus PLEs that are clinically relevant is whether PLEs are distressing and/or persistent. The current study used three waves of Adolescent Brain Cognitive Development℠ (ABCD) study PLEs assessments to examine the extent to which persistent and/or distressing PLEs were associated with relevant baseline risk factors (e.g., cognition) and functioning/mental health service utilization domains. Four groups varying in PLE persistence and distress endorsement were created based on all available data in ABCD Release 3.0, with group membership not contingent on complete data: persistent distressing PLEs (n = 272), transient distressing PLEs (n = 298), persistent non-distressing PLEs (n = 221), and transient non-distressing PLEs (n = 536) groups. Using hierarchical linear models, results indicated youth with distressing PLEs, whether transient or persistent, showed delayed developmental milestones (β = 0.074, 95%CI:0.013,0.134) and altered structural MRI metrics (β = -0.0525, 95%CI:-0.100,-0.005). Importantly, distress interacted with PLEs persistence for the domains of functioning/mental health service utilization (β = 0.079, 95%CI:0.016,0.141), other reported psychopathology (β = 0.101, 95%CI:0.030,0.170), cognition (β = -0.052, 95%CI:0.-0.099,-0.002), and environmental adversity (β = 0.045, 95%CI:0.003,0.0.86; although no family history effects), with the interaction characterized by greatest impairment in the persistent distressing PLEs group. These results have implications for disentangling the importance of distress and persistence for PLEs with regards to impairments, including functional, pathophysiological, and environmental outcomes. These novel longitudinal data underscore that it is often only in the context of distress that persistent PLEs were related to impairments.

Front Psychiatry 2022; 13:894218.

Abstract
BACKGROUND Psychological symptoms and non-suicidal self-injury (NSSI) are independently associated with suicide attempts (SA). Yet, no study has tested the interaction effects between NSSI and psychological symptoms on SA in community adolescent populations, or examined whether the interaction varies by gender. We sought to examine the interaction effects of NSSI and psychological symptoms on SA in adolescents and explore gender differences. METHODS A school-based health survey in 3 provinces in China was conducted between 2013-2014. 14,820 students aged 10-20 years completed standard questionnaires, to record the details of various psychological symptoms, SA and NSSI. RESULTS Psychological symptoms and NSSI were independently associated with a higher likelihood of SA in both boys and girls (p < 0.001). Adolescents with psychological, conduct or social adaptation symptoms without concurrent NSSI, were twice as likely to report SA (corresponding RORs were 1.80, 1.80 and 2.16, respectively; p < 0.01) than those who reported NSSI. Male adolescents with psychological, emotional, conduct or social adaptation symptoms had a higher risk of SA in the non-NSSI group than the NSSI group (corresponding RORs were 2.85, 2.26, 2.30 and 3.01 respectively; p < 0.01). While in girls, only adolescents with social adaptation symptoms had a higher risk of SA in the non-NSSI group than NSSI group (corresponding RORs was 1.71, p < 0.05). In the non-NSSI group, boys reporting psychological symptoms exhibited a higher likelihood of a SA than their female counterparts. CONCLUSION Psychological symptoms and NSSI are independently associated with an increased risk of SA in adolescents. However, to some extent, NSSI may reduce the risk of SA among individuals with psychological symptoms, especially in boys.

Abstract
Psychotic experiences (PEs) are prevalent in the general population, particularly in adolescents. PEs are associated with various negative outcomes such as psychotic, depressive, anxiety and post-traumatic stress disorders and suicidal behavior. Recent studies in the general population have suggested that what makes PEs relevant is not so much the experiences per se, but their association with non-psychotic comorbidity and other transdiagnostic domains. Thus, there is a need for a better understanding of how PEs exist in a larger psychopathological context in adolescents. In the present study we aimed to explore this, using latent profile analysis (LPA) to identify different patterns in which PEs, psychiatric symptoms and psychological processes co-occur. LPA was conducted using data from an adolescent general population subsample (n = 335) with PEs. We conducted LPA, using measures of PEs, psychiatric symptoms and behaviors (depression, anxiety post-traumatic stress disorder and suicidal behavior) and cognitive and affective processes of entrapment/defeat and emotional regulation as manifest variables. We found that the best fit was obtained with a four-class solution that distinguished primarily between different levels of overall severity: "low symptomatology" (19.1%), "mild-moderate symptomatology" (39.4%), "moderate symptomatology" (33.7%); "high symptomatology" (7.8%). Levels of depression, post-traumatic stress symptoms and defeat/entrapment were most differentiated between classes. The high symptomatology group showed the highest scores in all psychiatric symptoms suicidal ideation, and emotional/cognitive domains, except in cognitive reappraisal. This group also showed the highest usage of emotional suppression. Our results suggest that the assessment of mental health risk in adolescents should be aware that PEs exist in a broad context of other domains of psychopathology and transdiagnostic cognitive and affective processes.

Abstract
OBJECTIVE Paranoia may be particularly prevalent during adolescence, building on the heightened social vulnerabilities at this age. Excessive mistrust may be corrosive for adolescent social relationships, especially in the context of mental health disorders. We set out to examine the prevalence, symptom associations, and persistence of paranoia in a cohort of young people attending child and adolescent mental health services. METHOD A total of 301 patients (11-17 years old) completed measures of paranoia, affect, peer difficulties and behavioural problems. Clinicians also rated each participant's psychiatric symptoms. Patterns of association were examined using linear regressions and network analyses. In total, 105 patients repeated the measures several months later. RESULTS Most of the adolescents had affective disorders (n = 195), self-harm/suicidality (n = 82), or neurodevelopmental conditions (n = 125). Few had suspected psychosis (n = 7). Rates of paranoia were approximately double compared with previous reports from the general population. In this patient sample, 35% had at least elevated paranoia, 15% had at least moderate paranoia, and 6% had high paranoia. Paranoia had moderate associations with clinician-rated peer difficulties, self-harm, and trauma, and small associations with clinician-rated social anxiety, depression, generalised anxiety, and educational problems. Network analyses showed paranoia had the strongest unique relationship with peer difficulties. Paths from peer difficulties to anxiety, self-harm, post-traumatic stress disorder symptoms, and behavioural problems were all via paranoia. Both self-harm and post-traumatic stress disorder were solely associated with paranoia in the network. Paranoia remained persistent for three-quarters and was associated with greater psychological problems over time. CONCLUSION Paranoia is relatively common and persistent across a range of clinical presentations in youth. When paranoia occurs alongside emotional problems, important peer interactions may be adversely affected. Wider consideration of paranoia in adolescent patients is needed.

Abstract
Psychotic experiences (PEs) are robustly associated with subsequent non-suicidal self-injury (NSSI) and suicide attempts, but questions remain as to the temporal relation and underlying cause of this association. Most investigations have incorporated only two waves of data, and no study has comprehensively investigated mediating pathways. This study aimed to investigate both the PE-NSSI and PE-suicide attempt association, and their relevant mediators, across three waves of prospective data. Participants were from an Australian prospective longitudinal cohort of 1100 adolescents (12-17 years); data were collected at three time points over 2 years. NSSI and suicide attempts were measured using the Self-Harm Behaviour Questionnaire. Items from the Diagnostic Interview Schedule for Children were used to assess four PE subtypes (auditory hallucinatory experiences [HEs] and three delusional experiences). Potential mediators of interest included: psychological distress, self-reported mental disorders, self-esteem, recent traumatic life events (e.g. bullying, sexual assault), emotion regulation, and impulsivity/other personality traits. Analyses were adjusted for sociodemographics and substance use. Auditory HEs were indirectly associated with future NSSI and suicide attempts via recent traumatic life events, high psychological distress, and low self-esteem, across three waves of data. Other PE subtypes were generally not associated with incident NSSI/suicide attempts at 1- and 2-year follow-up, either directly or indirectly. These findings highlight the importance of screening for auditory HEs when assessing a young person's self-harm/suicide risk. Clinical assessment would be further enhanced by a comprehensive review of recent interpersonal traumatic events, as well as levels of self-esteem and distress.

Abstract
Self-harm and personality psychopathology have been linked, with the most robust correlations existing between negative affectivity and self-harm. Psychological pain, an emotionally-based aversive feeling, has been linked to self-harm. Considering the connection between personality psychopathology and self-harm, psychological pain may enhance self-harm risk. Participants: Analyses were conducted on 525 undergraduate students in the Spring and Fall semesters of 2019. Methods/Results: Correlation analyses indicated that self-harm was moderately correlated with Negative Affectivity, Detachment, Antagonism, Disinhibition, and Psychoticism. Additionally, self-harm was correlated with psychological pain. When examining if psychological pain moderates the relation between personality psychopathology and self-harm, results were mixed. In the cases of Disinhibition and Psychoticism, psychological pain enhanced self-harm. There was no moderating effect on the relations with Negative Affectivity, Detachment, or Antagonism. Conclusions: These findings support the role of psychological pain in self-harm outcomes for those experiencing personality psychopathology; however, this varies depending on the maladaptive traits.

Abstract
BACKGROUND Suicide in the young population has been an urgent issue worldwide. The study aimed to assess the overall prevalence of suicide ideation and the associations between adolescent suicide and psychiatric distress/ psychiatric morbidity, as well as the myths and help-seeking behavior of adolescents with suicide ideation. METHOD The nationwide community-based telephone interviews were conducted with adolescents aged between 15 to 19 for five consecutive years (2015-2019). The measurements included demographic variables, the five-item Brief Symptom Rating Scale (BSRS-5), and help-seeking experiences of formal medical services or psychological consultations. Stepwise multiple regression analysis was performed to examine which of the five symptoms and demographic variables had discriminative validity for suicidal ideation. RESULTS Among 727 participants, the prevalence of lifetime and one-week suicidal ideation was 11.4% and 2.8%, respectively. Adolescents with lifetime/ one-week suicidal ideation and with psychiatric morbidity (BSRS-5≥6) sought psychiatric service more than their counterparts (p<0.001). Female, depression, hostility, and anxiety were significantly associated with suicidal ideation in adolescents. LIMITATIONS Telephone interview and structured questionnaire. CONCLUSION Adolescents with psychiatric morbidity who have sought help should be carefully monitored for suicidal ideation by parents, teachers, mental health workers, and psychiatric specialists altogether.

Abstract
BACKGROUND Persistent psychotic experiences (PEs) may increase risk for mental disorders, non-suicidal self-injury (NSSI), and suicide attempts, relative to PEs that are more transient and remitting in nature. Most investigations of PE persistence have incorporated only two waves of data, and have not investigated the persistence of different PE subtypes and their association with future NSSI and suicide attempts. This study aimed to investigate the association between PE persistence, NSSI, and suicide attempts using three waves of prospective data. A secondary aim was to investigate potential reverse pathways where self-injurious behaviour (and its persistence) instead precedes subsequent PE occurrence. METHOD Participants were 1100 adolescents (12-17 years) from an Australian prospective cohort study; with three time points over two years. The Self-Harm Behaviour Questionnaire was used to assess NSSI and suicide attempts. Four PE subtypes (auditory hallucinatory experiences [HEs], and three delusional experiences) were assessed using the Diagnostic Interview Schedule for Children. Logistic regression analyses were conducted where PEs was grouped into five categories according to their persistence across the three waves of data. Analyses were adjusted for sociodemographics and substance use. RESULTS Overall, persistence of PEs (with endorsement of PE across two or three waves) was associated with the highest risk of incident NSSI and suicide attempts at 1- and 2-year follow-up (OR range: 2.57-12.25), whereas remitted PEs (with endorsement of PE at baseline only) were not associated with increased risk of future NSSI or suicide attempts. This pattern of association was evident for auditory HEs but not for most other PE subtypes; although some estimates had wide confidence intervals. There was no support for reverse temporality. CONCLUSION Our findings support and extend the two-wave cohort literature demonstrating that PEs which persist over time are more robust predictors of future NSSI and suicidal behaviour. Auditory HEs that are persisting in nature are an important but under-recognised risk factor for NSSI and suicide attempts during adolescence, and current findings should inform clinical guidelines into the predictors of self-harm and suicide risk at this life stage.

Abstract
Psychotic experiences (PE), below the threshold of psychotic disorder, are common in the general population. PE are associated with risk behaviors such as suicidality, non-suicidal self-injury (NSSI) and substance use. However, PE as specific or causal phenomena of these risk behaviors are still debated. We aimed to examine the longitudinal trajectories of PE from preadolescence to adolescence and their associated risk behaviors in adolescence. A total of 1138 adolescents from the Copenhagen Child Cohort 2000 were assessed for PE and risk behaviors (NSSI, suicide ideation and -attempts and substance use) at age 11 and 16 years, along with measures of general psychopathology and depressive symptoms specifically. Self-reported impact of general psychopathology tended to be associated with more PE persistence. PE were associated with all risk behaviors in cross section at both follow-ups. Persistent PE from ages 11 to 16 and incident PE at age 16 were associated with risk behaviors at age 16, whereas remitting PE from age 11 to 16 were not. After adjustment for co-occurring depressive symptoms and general psychopathology, all associations were markedly reduced. After exclusion of preadolescents who already had expressed risk behavior at age 11, PE in preadolescence did not stand out as an independent predictor of incident adolescent risk behaviors. The current study suggests that PE in preadolescence and adolescence may not play a direct causal role regarding NSSI, suicidality, and substance use. However, PE are still useful clinical markers of severity of psychopathology and associated risk behaviors.

Abstract
PURPOSE Research has produced inconsistent results with respect to whether the association between psychotic experiences and suicidal behavior is independent of co-occurring clinical and socioenvironmental factors, despite substantial evidence linking the two phenomena. This study tests whether a comprehensive set of demographic, socioenvironmental, and clinical variables account for the statistical association between psychotic experiences and suicidal behaviors. METHODS We utilized blocked multivariable logistic regression models to analyze the association between 12-month psychotic experiences and 12-month suicide behaviors (ideation, plan, and attempt) on a subsample (N = 2307) of the National Comorbidity Survey Replication. The models adjusted for socio-demographic characteristics, environmental factors in the form of childhood adversity, mental health service utilization, and psychiatric and substance abuse disorders. RESULTS Psychotic experiences were significantly associated with suicidal ideation, even after adjusting for socio-demographics, childhood adversity. However, the significant association between psychotic experiences and suicidal ideation was not robust to the inclusion of mental health service utilization and psychiatric disorders. There was no significant association between psychotic experiences and suicide plan. Psychotic experiences were associated with a significantly increased risk of reporting suicide attempts (OR 6.52; 95% CI 1.36-31.11), even after adjusting for the full set of variables. CONCLUSIONS Although psychotic experiences were not associated with suicidal ideation after statistical adjustments, psychotic experiences were associated with a significantly increased risk of suicide attempts after the inclusion of common risk factors and co-morbidities. Thus, psychotic experiences should be included in routine psychiatric assessments to identify the individuals most at risk for attempting suicide.

Abstract
BACKGROUND Unintentional injuries are a leading cause of morbidity and mortality in children of all ages. Prevention strategies require knowledge of risk factors, and behavior and psychiatric disorders have been suggested to influence the risk of injury during childhood. While externalizing disorders have been found to increase the risk for injuries, results are mixed regarding internalizing disorders, such as affective and anxiety conditions, and Autism Spectrum Disorders (ASD). There is a need for large scale studies relying on robust data sources. The aim of the present study was to examine the association between psychiatric disorders and injuries requiring medical attention, in a large population-based cohort of 350,000 children and adolescents in Sweden. METHODS Data were obtained from the regional health care database Vega. Psychiatric diagnoses and injury diagnoses obtained during 2014-2018 for individuals aged 0-17 years in 2016 were extracted. Descriptive statistics were used to examine differences in 5-year injury prevalence between children with and without different psychiatric diagnoses. Logistic regression was used in age-stratified models to test the association between psychiatric diagnoses and injuries requiring medical attention. RESULTS The results show an increased risk for concurrent injuries in general, but the patterns vary by age and psychiatric disorder. Externalizing disorders and anxiety conditions were associated with concurrent injuries, while individuals with ASD had a lower risk for most injuries included. Affective disorders were associated with an increased risk for wounds, concussion, complications and poisoning, while the risk for fractures was decreased. Self-inflicted injury was more common in all psychiatric conditions investigated during adolescence, except for ASD. Children and adolescents with many types of psychiatric disorders were also at increased risk for a concurrent maltreatment diagnosis. CONCLUSIONS A general pattern of increased risk for concurrent injuries in children and adolescents with most psychiatric diagnoses was found, but the associations vary by age and type of psychiatric disorder. The results add to the literature on risk factors for injuries in children and adolescents, supporting diagnosis specific patterns. Several psychiatric diagnoses were associated with a marked increase in injury risk, indicating a high burden of disease for affected individuals.

Abstract
BACKGROUND Transgender people experience high rates of suicidality and self-harm. Past research has established a range of correlates of suicidality/self-harm among transgender people but little is known about whether these correlates are similar for transgender and cisgender people. AIMS The aim of this study was to test whether a range of potential demographic and psychosocial correlates of suicidality/self-harm hold for both transgender and cisgender people living in Aotearoa/New Zealand and Australia. METHODS An online survey was completed by 700 adults living in Aotearoa/New Zealand (n = 328) or Australia (n = 372). Targeted advertising was used to recruit transgender respondents (n = 392) and cisgender respondents (n = 308). Participants completed questions about demographics, discrimination (the Everyday Discrimination Scale), distress (the Kessler-10 scale), social support (the Multi-Dimensional Scale of Perceived Social Support), resilience (the Brief Resilience Scale), suicidality (the Suicidal Ideation Attributes Scale and other questions about ideation/attempts), and self-harm (the Deliberate Self-Harm Inventory). RESULTS Lifetime suicidal ideation, lifetime suicide attempts, and lifetime self-harm were more common among transgender participants. Discrimination was associated with lifetime suicide attempts and lifetime self-harm, particularly for transgender participants. Distress was consistently associated with recent suicidality and self-harm for transgender participants. Younger cisgender participants were more likely to report lifetime self-harm. Recent suicidal ideation was associated with lower social support among transgender participants but with lower resilience among cisgender participants. DISCUSSION These findings reaffirm and expand on past research on suicidality/self-harm among transgender or cisgender people and demonstrate the relevance of tackling discrimination and distress experienced by transgender people. In addition, the findings highlight the importance of meeting additional social support needs among transgender people to help prevent suicide and self-harm.

Abstract
OBJECTIVE Psychotic experiences, including auditory hallucinatory experiences (HEs), are strongly associated with both suicidal thoughts and behaviour. This study examined their role in the ideation-to-attempt transition in adolescents, including their direct and indirect effect via potential mediators. METHOD Participants were from an Australian prospective longitudinal cohort of 1669 adolescents (12-17 years); of which a subsample endorsing baseline suicidal ideation (n = 216) was the focus of most analyses. Suicidal thoughts and behaviours were measured using the Self-Harm Behaviour Questionnaire. The Diagnostic Interview Schedule for Children was used to assess auditory HEs. Potential mediators of interest were psychological distress and Interpersonal Theory of Suicide (IPTS) constructs. RESULTS Among adolescents reporting suicidal ideation at baseline (n = 216), 6.5% had attempted suicide during follow-up. The size of auditory HEs' univariate effect suggests a possible strong relationship with increased risk of incident suicide attempts (OR = 2.40; 95%CI = 0.76-7.56); however, there was inadequate statistical power to produce a precise estimate. When HEs were accompanied by distress there was a nine-fold increased risk of acting on suicidal thoughts. Distress was independently associated with risk of attempt transition (OR = 4.09), whereas IPTS constructs were poor explanatory variables in most models. CONCLUSION Adolescents with psychological distress and auditory HEs are at high risk of incident suicide attempts. Further investigations on the role of negative/distressing content of hallucinations in the ideation-to-attempt transition are warranted.

Abstract
OBJECTIVES Psychotic experiences such as hallucinations and delusions are reported by approximately 7.2% of the general population, even in the absence of a psychotic disorder. Individuals who report such psychotic experiences are significantly more likely to endorse suicidal ideation and behavior across several large epidemiological samples. This study aimed to determine whether individuals who reported psychotic experiences and suicidal behavior would subjectively endorse a causal relationship between these two clinical phenomena. METHODS Five open-ended questions were asked via online survey to 12 college students who had previously reported both hallucination-like experiences and suicidal behavior in a quantitative survey. Thematic analysis was used to analyze open-ended responses. RESULTS The majority of respondents, n (%) = 11 (91.6), did not endorse a notable subjective relationship between psychosis and suicidal ideation or suicide attempts. However, respondents did spontaneously report that stigma and fear may drive suicidal ideation among people who report psychotic experiences and other symptoms of psychological distress. CONCLUSIONS These findings are generally inconsistent with the hypothesis that psychotic experiences are directly related to suicidal behavior, and are consistent with the alternative hypothesis that both psychotic experiences and suicidal behavior are indicators of common underlying factors such as general psychological distress, potentially exacerbated by stigma.

Abstract
BACKGROUND Existing research shows that adults with an autism spectrum disorder (ASD) are more vulnerable to develop overt psychosis. However, studies investigating (subclinical) psychotic experiences (PE) in ASD are scarce, and it is unknown if PE are accompanied with more distress in adults with ASD compared to the general population. This study examined lifetime PE and accompanying distress, momentary PE levels, and the impact of daily life stress and negative affect (NA) on momentary PE in males and females with ASD compared to controls. METHODS In 50 adults with ASD (males N= 26, females N= 24) and 51 adults without ASD (males N= 26, females N= 25), the Community Assessment of Psychic Experiences (CAPE) was used to analyze group differences in frequency and distress of lifetime subclinical positive, negative, and depressive symptoms. The Experience Sampling Method (ESM) was used to measure momentary PE, NA, and stress (activity-related, event-related, and social stress) for 10 days. Multilevel analyses were conducted to test whether stress and NA were associated with momentary PE and whether these associations were modified by group or sex. RESULTS Adults with ASD reported more lifetime CAPE negative and depressive symptoms, but similar levels of PE, than controls. Higher levels of accompanying distress were found in participants with ASD for each subscale. With respect to ESM momentary PE, higher levels were reported by adults with ASD and a stronger association between event-related stress and momentary PE was found compared to controls. This was not the case for NA, activity-related, and social stress. Overall, no significant differences between male and female outcomes were found. CONCLUSION Adults with ASD are more prone to encounter lifetime subclinical negative and depressive symptoms and accompanying distress compared to adults without ASD. Similar levels of lifetime PE in both groups were still accompanied with more distress in the ASD group. Furthermore, higher levels of ESM momentary PE were found in participants with ASD. Additionally, event-related stress may act as a risk factor for PE in both females and males with ASD, with a stronger risk-increasing effect than in their control counterparts.

Abstract
BACKGROUND To what extent Psychotic Like Experiences (PLEs) are associated with nonpsychotic psychiatric disorders and whether the number of PLEs is associated with higher rates of psychiatric disorders remains unclear. METHODS The sample was composed of 34,653 civilian participants, aged 18 years and older from wave 2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). This was a representative sample of the non-institutionalized U.S. POPULATION Twenty-two PLEs were assessed. Lifetime prevalence of psychiatric disorders (any mood, anxiety, substance use and personality disorders, PTSD, ADHD, and suicide attempts) according to the number of PLEs were calculated. RESULTS Almost a third (26.69%) of respondents reported experiencing at least one type of PLEs. There was a gradual association between the number of PLEs and the presence of a nonpsychotic psychiatric disorder (ranging from 5.68%in participants with no PLEs up to 99.53% in those with five or more PLEs). This association with PLE was significant for each of the 25 psychiatric disorders examined regardless of the number of PLEs. Lifetime prevalence of PLEs were significantly higher among the younger respondents, women, non-married, unemployed, high educational level and those with low family income. CONCLUSION There is a gradual increase in the magnitude of the association of the numbers of PLEs for each of the 25 nonpsychotic psychiatric disorders examined. Having at least one PLE is strongly associated with the presence of a psychiatric disorder.

Abstract
BACKGROUND Childhood trauma, psychosis risk, cognition, and depression have been identified as important risk markers for suicidal behaviors. However, little is known about the interplay between these distal and proximal markers in influencing the risk of suicide. We aim to investigate the interplay between childhood trauma, cognitive biases, psychotic-like experiences (PLEs) and depression in predicting suicidal behaviors in a non-clinical sample of young adults. METHODS In total, 3495 young adults were recruited to an online computer-assisted web interview. We used the Prodromal Questionnaire to assess PLEs. Childhood trauma was assessed with the Traumatic Experience Checklist (three items) and Childhood Experience of Care and Abuse Questionnaire (CECA.Q, three items). Cognitive biases were assessed with a short version of the Davos Assessment of Cognitive Biases Scale. Suicidality, psychiatric diagnoses, and substance use were screened with a self-report questionnaire. RESULTS Childhood trauma, as well as PLEs, was associated with an approximately five-fold increased risk of suicidal thoughts and plans as well as suicide attempts. Participants with depression were six times more likely to endorse suicidal behaviors. Path analysis revealed that PLEs, depression and cognitive biases are significant mediators of the relationship between trauma and suicidal behaviors. The model explained 44.6% of the variance in lifetime suicidality. CONCLUSIONS Cognitive biases, PLEs, and depression partially mediate the relationship between childhood trauma and suicidal behaviors. The interplay between distal and proximal markers should be recognized and become part of clinical screening and therapeutic strategies for preventing risk of suicidality.

Abstract
PURPOSE Suicidal thoughts and behaviors (STBs) have been a persistent problem worldwide. Identifying risk factors for STBs across distinct areas of the world may help predict who or where requires the greatest attention. However, risk factors for STBs are infrequently explored cross-nationally. The present study examined whether psychopathology prospectively predicts STBs across different areas of the world, and whether certain country-level factors moderate the degree of risk conferred. METHODS We conducted a meta-analysis of 71 longitudinal studies from 30 different countries that featured psychopathology-related variables predicting STB outcomes. Meta-regression was used to evaluate whether the following country-level factors modified risk: geographic region, income level, and degree of mental health structural stigma. RESULTS Over 90% of studies had been conducted in North America and Europe. When assessed by country income level, it was found that only one longitudinal study on psychopathology and STB was conducted outside of a high-income country. Moreover, less than 10% of studies were conducted in high structural stigma contexts. Meta-regression findings revealed that the variation in risk effect sizes across studies was not explained by models including country-level factors. CONCLUSIONS Our findings show critical underrepresentation of low- and middle-income countries, which account for a large proportion of global suicide deaths. This reveals a need to broaden the scope of longitudinal research on STB risk, such that countries across more regions, income levels, and degrees of structural stigma are fully accounted for. Such lines of research will improve generalizability of findings, and more precisely inform prevention efforts worldwide.

Abstract
Significant research questions persist regarding the short- and long-term outcomes of Latina adolescents who attempt suicide. To address these limitations, we utilize an ecodevelopmental framework to identify potential factors that shape differential outcomes following a suicide attempt. Through an exploratory, longitudinal, qualitative research design, we investigate two research questions: How do trajectories of well-being vary among Latina teens after a suicide attempt? What risk and protective factors might contribute to different trajectories? We conducted qualitative interviews with 17 Latina participants living in predominantly low-income households in New York City. Interviews took place within the 6 months following their suicide attempts, and again, 12 months later. Analysis revealed three distinct trajectories after a suicide attempt: resilience, tenuous growth, and chronic stress. Our findings elucidate potential factors that contribute to resilience following a suicide attempt and underscore the importance of prevention and intervention programs that foster adolescents' connectivity across ecodevelopmental contexts.

Abstract
The Interpersonal-Psychological Theory of Suicide (IPTS) has emerged as an empirically supported theory of suicide risk, yet few studies have utilized IPTS to examine the suicidal behaviors of Latina adolescents. In this study, we explore the cultural and developmental appropriateness, as well as the explanatory fit, of IPTS within a sample of Latina adolescents. Data for this project were drawn from qualitative interviews conducted with Latina adolescents with (n=30) and without (n=30) histories of attempted suicide. We employed a deductive qualitative approach to define and compare core constructs of IPTS (perceived burdensomeness, thwarted belongingness, and acquired capability), and then use qualitative comparative analysis to evaluate how core constructs were linked with the occurrence of a suicide attempt. Consistent with IPTS, perceived burdensomeness, thwarted belongingness, and acquired capability were present in 20 of the 30 adolescents who had attempted suicide, and absent in 22 of the 30 adolescents with no lifetime history of suicidal behaviors. Notably, alternative combinations of IPTS constructs were found in 10 cases of adolescents who attempted suicide, suggesting a need to adjust IPTS to fit the developmental and cultural contexts of Latina teens. Although our results suggest predominantly positive support for IPTS, participants varied in terms of how their experiences resonated with the conceptual definitions put forward by the theory. Ultimately, our findings point to the ways in which developmental tensions are exacerbated by broader sociocultural dynamics, contributing to a broader understanding of suicide risk among ethnic minority adolescents.

BACKGROUND Although massive studies have explored the risk factors of suicidal ideation (SI), the prevalence of SI and its associated factors in the hypertensive individuals are largely unknown. This study aims to investigate the factors associated with SI in the hypertensive individuals. METHODS Three thousand nine hundred eleven hypertensive individuals in Shandong, China were included in the analysis. SI was assessed by using a question from the NCS (National Comorbidity Survey). We used binary logistic regression analysis to explore the factors associated with SI, and path analysis to test the direct and indirect relationships between associated factors and SI among hypertensive patients. RESULTS The prevalence of SI in the hypertensive individual was19.6%. Psychological distress had the greatest direct (β = 0.640, p-value <0.01) and total effect (β = 0.640, p-value <0.01) on SI. Other factors including comorbidity (β = 0.090, p-value <0.01), gender (β = 0.088, p-value <0.01), marital status (β = - 0.037, p-value <0.01), economic status (β = - 0.106, p-value <0.01), residence (β = - 0.050, p-value <0.01), alcohol use (β = 0.011, p-value <0.01), exercise (β = - 0.114, p-value <0.01), hospitalization (β = 0.041, p-value <0.01) only had indirect effects on SI. Psychological distress was a mediator between SI and those variables. CONCLUSION A significant mediation effect of psychological distress on the associations between SI and some associated factors (i.e., economic status, comorbidity) was demonstrated.

Abstract
Psychotic symptoms have been found to be relatively common among adults with borderline personality disorder (BPD), and to be a marker of BPD severity, but are not recognised in daily clinical practice in these patients. This study is the first to examine the prevalence of psychotic symptoms in 15-18-year olds with BPD features. It was hypothesised that adolescents with full-threshold BPD would have significantly more psychotic symptoms than adolescents with sub-threshold BPD features, and that both these groups would have significantly more psychotic symptoms than adolescents with no BPD features. A total of 171 psychiatric outpatients, aged 15-18 years, were assessed using a structured interview for DSM-IV personality disorder and categorised into three groups: no BPD features (n = 48), sub-threshold BPD features (n = 80), and full-threshold BPD (n = 43). The groups were compared on measures of psychopathology and functioning (e.g. Youth Self Report, Symptom Check List-90-R, SOFAS). Adolescents with full-threshold BPD reported more psychotic symptoms than the sub-threshold BPD group (p < .001), and both these groups reported more psychotic symptoms than those with no BPD features (p < .001). Adolescents with full-threshold BPD reported more confusion (p < .01), paranoia (p < .001), visual hallucinations (p < .001) and strange thoughts (p < .01), than the other two groups. Psychotic symptoms predicted group membership, determined by BPD severity, after adjusting for other psychopathology and functional impairment (p < .01). Assessment of unusual perceptual experiences, paranoia or odd thoughts is highly clinically relevant in adolescents with BPD features, as these symptoms are associated with a more severe clinical presentation of BPD.

Abstract
BACKGROUND Subclinical psychotic experiences (PLEs) are among the frequently reported mental health problems in children/adolescents. PLEs identified in cross sectional studies of children/adolescents are associated with current and future mental health problems. These associations are stronger for PLEs that persist over time. Hence, it could be useful to examine which children/adolescents with PLEs at a first assessment (baseline) are more likely to have PLEs at subsequent assessments. METHODS We conducted a scoping review of studies that examined whether characteristics of children/adolescents (≤18 years) with PLEs at baseline predict whether PLEs are likely to be persistent or remittent at subsequent assessments. We included studies published between January 2002 and December 2017, conducted on general child/adolescent populations of ≥300 individuals, that provided data on PLEs for at least 2 time points, had available follow-up data for ≥50% of those assessed for PLEs at baseline and targeted for follow-up examination, and reported the differences between individuals with PLEs that persisted or remitted during the study period. RESULTS Six studies met our criteria. Each of them investigated a wide range of baseline characteristics but no predictor of persistence was replicated. CONCLUSIONS Our knowledge about which children/adolescents with PLEs at an initial assessment are likely to have persistent PLEs at subsequent assessments is sparse. A handful of predictors of persistent PLEs have been investigated so far, and none replicated. A better understanding of these predictors would be an important complement to investigations examining the evolution of PLEs and of mental health problems in children/adolescents.

Abstract
AIM Psychotic experiences, including delusions and hallucinations, and their attenuated forms have been recently suggested as a significant but under-recognized marker of suicide risk. However, the relationship between attenuated positive symptoms and suicide has not yet been clearly demonstrated in individuals at ultra-high risk (UHR) for psychosis. Here, we investigated the effect of attenuated positive symptoms on suicidal ideation in UHR individuals. METHODS Fifty-three healthy controls (HCs) and 74 UHR individuals participated in the present study. All participants were assessed for the intensity of suicidal ideation and depressive symptoms at baseline. The effect of attenuated positive symptoms on suicidal ideation in the UHR group was examined using a multiple linear regression analysis after adjustment for concurrent depressive symptoms. RESULTS UHR participants were found to have significantly greater suicidal ideation and more severe depressive symptoms compared to those of HCs. The regression model demonstrated that suspiciousness significantly increased suicidal ideation in UHR participants, independent of the severity of depressive symptoms. CONCLUSION The findings of the present study suggest that suspiciousness may serve as a risk indicator for suicide in clinical practice for UHR individuals. It is crucial to focus on the risk of suicide in the UHR population, as they require sufficient clinical attention and proper management for crises related to their unusual and confusing experiences.

Adolescent personality traits, low self-esteem and self-harm hospitalisation: a 15-year follow-up of the Norwegian Young-HUNT1 cohort. Eur Child Adolesc Psychiatry 2019; 28:329-339.

Abstract
Affective disorders are closely related to self-harm and suicidal behaviours. Less is known about how adolescent personality traits and self-esteem influence the development of later self-harm. We examined associations between personality traits such as neuroticism, psychoticism and extroversion, and self-esteem, in adolescence, and the risk of future self-harm hospitalisation. Baseline information from 13 to 19-year-old participants in the Norwegian Young-HUNT1 study in 1995-97 (n = 8965) was linked to endpoint data recorded from participants' hospital records, describing self-harm hospitalisation episodes within the catchment area. Crude and adjusted hazard ratios (HR) were estimated by Cox regression analyses. A one-unit increase on the 0-6 scale for neuroticism was associated with a HR of 1.29, 95% confidence interval (CI) 1.14-1.47. Corresponding HR for psychoticism was 1.30, 95% CI 1.03-1.63 per unit increase, and for extroversion risk was reduced (HR 0.89, 95% CI 0.77-1.04). Positive perception of self-esteem was more strongly associated with reduced risk of self-harm hospitalisation (HR per unit increase on the 0-12 scale was 0.74, 95% CI 0.68-0.82). Additional adjustment for alcohol use and symptoms of combined anxiety and depression symptoms attenuated effect estimates, in particular for neuroticism (HR 1.13, 95% CI 0.96-1.32) and psychoticism (HR 1.07, 95% CI 0.82-1.40). In contrast, self-esteem associations remained largely the same after adjustment. Our results indicate that brief assessments of personality and self-esteem might add additional relevant information, and could be included as a supplement to standard suicidal risk assessment in adolescents.

Abstract
PURPOSE The association between psychotic experiences (PEs) and non-accidental self-injury (NASI; including self-harm and suicide attempts) is well established, although variables influencing this relationship have not been comprehensively examined. This study aimed to investigate (1) the cross-sectional PE-NASI association before and after adjustment for confounders, and (2) the individual contribution of each confounding and potentially mediating variable to the association. METHODS A random sample of Australian adolescents aged 14-17 years (n = 1998) completed self-report questions regarding any self-harm, suicidality or PEs experienced in the past 12 months in 2013-2014 as part of the Young Minds Matter Survey, a national household survey. We conducted logistic regression analyses to investigate the association between NASI and PEs, after controlling for confounders (sociodemographics, substance use, and parental mental illness) as well as the influence of potential mediators (major depression, bullying, psychological distress, sleep, self-esteem, disordered eating behaviour, social isolation, and intervention factors). RESULTS Except for special messages, all PE subtypes (auditory and visual hallucinatory experiences [HEs], and two of the three delusional experiences [DEs]) were associated with NASI after adjustment for confounders (OR range: 2.60-5.21). Depression and psychological distress significantly influenced all PE-NASI associations, where depression appeared to fully explain the DE-NASI association, and partially attenuate the HE-NASI association. Variables such as parental mental illness, disordered eating behaviour, and social isolation had negligible effects in nearly all self-harm and attempted suicide models. CONCLUSIONS Adolescents reporting any PE in the past 12 months reported increased likelihood of NASI in the same time period and, auditory HEs in particular, were strongly and independently associated with self-harm and suicide attempts. These results highlight the importance of PEs as indicators of risk of self-injurious behaviour among Australian youth.

Abstract
Hallucinations in children and adolescents are now known to occur on a continuum from healthy to psychopathology-related phenomena. Although hallucinations in young populations are mostly transient, they can cause substantial distress. Despite hallucinations being widely investigated, research so far has had limited implications for clinical practice. The present article has 3 main aims: (1) to review research findings since 2014 (when the last major review of the area was published); (2) to present assessment tools validated to measure hallucinations in children and adolescents; and (3) to discuss therapeutic strategies and clinical issues. We conclude by presenting a tailored care model for clinicians and outline future challenges for research.

Abstract
Derogatis' Symptom Checklist-90-Revised (SCL-90-R) is one of the most widely used measures of psychological distress in both the clinical and the research settings, although its factor structure is still debated. In this study, the factor structure of the SCL-90-R has been investigated in two independent samples of Italian adolescents. Two samples of 817 (urban sample) and 507 (rural sample) adolescents attending high schools were involved. Confirmatory factorial analysis (CFA) was used alongside hierarchical nested, progressively constrained models to assess configural, metric and scalar invariance of the best models fitted by CFA. The standard nine-factor structure of the SCL-90-R resulted reproducible and invariant between the two samples, in both its correlated and hierarchical second-order implementations. Estimated reliability of the nine scales of the SCL-90-R was optimal. This study also confirmed the reproducibility of the bifactor models of the SCL-90-R with nine orthogonally independent factors and with nine correlated primary factors, which have been tested in some recent studies. Overall, the SCL-90-R measures both common and unique features of psychological distress in community samples. The measurement invariance across different levels of psychological distress in the factor structure of the SCL-90-R is an issue deserving further testing and investigation.

Abstract
IMPORTANCE Recent research has highlighted that psychotic experiences are far more prevalent than psychotic disorders and associated with the full range of mental disorders. A particularly strong association between psychotic experiences and suicidal behavior has recently been noted. OBJECTIVE To provide a quantitative synthesis of the literature examining the longitudinal association between psychotic experiences and subsequent suicidal ideation, suicide attempts, and suicide deaths in the general population. DATA SOURCES We searched PubMed, Excerpta Medica Database, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO from their inception until September 2017 for longitudinal population studies on psychotic experiences and subsequent suicidal ideation, suicide attempts, and suicide death. STUDY SELECTION Two authors searched for original articles that reported a prospective assessment of psychotic experiences and suicidal ideation, suicide attempts, or suicide death in general population samples, with at least 1 follow-up point. DATA EXTRACTION AND SYNTHESIS Two authors conducted independent data extraction. Authors of included studies were contacted for information where necessary. We assessed study quality using the Newcastle-Ottawa Quality Assessment Scale. We calculated pooled odds ratios using a random-effects model. A secondary analysis assessed the mediating role of co-occurring psychopathology. MAIN OUTCOMES AND MEASURES Psychotic experiences and subsequent suicidal ideation, suicide attempts, and suicide death. RESULTS Of a total of 2540 studies retrieved, 10 met inclusion criteria. These 10 studies reported on 84 285 participants from 12 different samples and 23 countries. Follow-up periods ranged from 1 month to 27 years. Individuals who reported psychotic experiences had an increase in the odds of future suicidal ideation (5 articles; n = 56 191; odds ratio [OR], 2.39 [95% CI,1.62-3.51]), future suicide attempt (8 articles; n = 66 967; OR, 3.15 [95% CI, 2.23-4.45]), and future suicide death (1 article; n = 15 049; OR, 4.39 [95% CI, 1.63-11.78]). Risk was increased in excess of that explained by co-occurring psychopathology: suicidal ideation (adjusted OR, 1.59 [95% CI, 1.09-2.32]) and suicide attempt (adjusted OR, 2.68 [95% CI, 1.71-4.21]). CONCLUSIONS AND RELEVANCE Individuals with psychotic experiences are at increased risk of suicidal ideation, suicide attempts, and suicide death. Psychotic experiences are important clinical markers of risk for future suicidal behavior.

Abstract
Psychotic experiences (PEs), including hallucination- and delusion-like experiences, are robustly associated with self-injurious thoughts and behaviours (SITB) in the general population. However, it remains unclear as to why there is an association. The purpose of this systematic review was to elucidate the role of other factors that influence the association between PEs and SITB and, in doing so, highlight potential mechanisms underlying the relationship. A search of electronic international databases was undertaken, including PubMed, PsycINFO and EMBASE, and eligible studies were grouped according to seven confounder categories: sociodemographics, mental disorders, alcohol and substance use, environmental, psychological, intervention and family history/genetic factors. The systematic search strategy identified 41 publications reporting on 1 39 427 participants from 16 different countries. In the majority of studies, where adjustment for other variables occurred, the association between PEs and SITB persisted, suggesting PEs have an independent role. Common mental disorders, psychological distress and negative environmental exposures explained a substantial amount of the variance and therefore need to be considered as potential underlying mechanisms. There was high variability in the variables adjusted for in these studies, and so the question still remains as to whether the association between PEs and self-harm/suicidality can be attributed (fully or in part) to confounding and mediating factors or directly causal mechanisms. Regardless of causality, the now extensive literature reporting an association between these two clinical phenomena supports the broad usefulness of PEs as an indicator of risk for SITB.

Abstract
Nonsuicidal self-injury (NSSI) usually starts during adolescence and is associated with an array of psychological and psychiatric symptoms and future suicide attempts. The aim of this study is to determine prospective predictors, mediators and moderators of NSSI in adolescent community samples in order to target prevention and treatment strategies. Two team members searched online databases independently. Thirty-nine studies were included in the review. Several variables were seen to prospectively predict NSSI: female gender, family-related variables, peer victimisation, depression, previous NSSI and self-concept. Few studies analysed mediators and moderators. Low self-concept was highlighted as a relevant moderator in the relationship between intra/interpersonal variables and NSSI. Implications of these findings are discussed. The considerable heterogeneity between studies posed a limitation to determine robust predictors of NSSI. Further prospective studies using standardised measures of predictors and outcomes are needed to ascertain the most at risk individuals and develop prevention strategies.

Ethical practices in community-based research in non-suicidal self-injury: A systematic review. Asian J Psychiatr 2017; 30:127-134. [PMID: 28903081 DOI: 10.1016/j.ajp.2017.08.015] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2017] [Accepted: 08/28/2017] [Indexed: 11/20/2022]
Abstract
BACKGROUND The growing interest in community-based research on non-suicidal self-injury (NSSI) reflects the high prevalence rates found among vulnerable adolescents and young adults. A significant concern in research with vulnerable populations, and on sensitive topics, is the development of an ethical framework that protects the needs and rights of the participants while responding to researchers' goals and limitations and the broader clinical and public health concerns. AIM The aim of the present study was to review the ethical practices followed in community-based research on NSSI. METHOD A systematic review of literature was conducted, based on PRISMA guidelines, on community-based surveys in NSSI, published between 1995 and 2016. A total of 93 studies were included in the review. RESULTS The results examine a range of ethical issues; the procedures for consent and assent for study participation, protection of confidentiality and the limits of confidentiality, assessment of imminent risk of suicide and subsequent processes, and debriefing measures. The interaction between the study characteristics and the reported ethical procedures has been examined, with a focus on participant age, study design (cross-sectional or longitudinal), survey modality (paper-based survey or online survey) and primary variable/s of interest (only NSSI or NSSI and suicidal ideation/behavior) under study. The review describes the typical ethical practices in community-based research on NSSI, identifies the gaps in the existing literature, and has implications for the formulation of best-practice guidelines.
