Longitudinal relationships of psychotic-like experiences with suicidal ideation and self-harm in adolescents

Longitudinal trajectories of psychotic-like experiences influence adolescent suicidal ideation: The mediating role of depressive symptoms

BACKGROUND

Psychotic-like experiences (PLEs) are strongly associated with poor mental health among adolescents. This study aims to investigate distinct longitudinal trajectories of the PLEs and their relationship to suicidal ideation (SI), as well as to evaluate the mediating effect of depressive symptoms on this link.

METHODS

A total of 7529 Chinese adolescents were surveyed on PLEs online during April 21 to May 12, 2021 (Time 1, T1), December 17 to 26, 2021 (Time 2, T2), and May 17 to June 5, 2022 (Time 3, T3). Depressive symptoms and SI were assessed at T1 and T3.

RESULTS

The prevalence of frequent PLEs across the three surveys was 13.5 %, 13.2 %, and 11.0 %, respectively. Five PLEs trajectories were identified: resistance (74.4 % of the sample), recovery (9.2 %), delayed-dysfunction (6.6 %), relapsing/remitting (7.0 %), and chronic-dysfunction (2.8 %). Adolescents in recovery, delayed-dysfunction, relapsing/remitting, and chronic-dysfunction trajectories compared with those in the resistant group were all more likely to experience SI at T3 after adjusting for a wide range of covariates. Depressive symptoms partially mediated the effects of PLEs trajectories (relative to the resistance trajectory) on SI (95 % CIs: 0.07-0.13, 0.37-0.48, and 0.28-0.41 for relapsing/remitting, delayed-dysfunction, and chronic-dysfunction trajectories, respectively).

CONCLUSIONS

PLEs are common among adolescents and have heterogeneity of change patterns. The association between PLEs trajectories and SI is partially mediated by depressive symptoms. Timely assessment and targeted interventions for specific PLEs are necessary to reduce the incidence of mental disorders.

The Cross-Sectional and Longitudinal Effects of Cumulative Multi-Contextual Risk on Psychotic-Like Experiences among Chinese Rural Adolescents

Psychotic-like experiences (PLEs) are common among adolescents and are associated with an increased risk of psychotic disorders and other mental health issues in adulthood. However, research on PLEs in rural adolescents is limited. Therefore, this study sought to investigate the cross-sectional and longitudinal effects of multiple contextual risk factors on PLEs among 1210 Chinese rural adolescents (45.6% boys; Mage = 13.70 years, SD = 0.81) across a one-year period, utilizing a cumulative risk model. Results revealed that bullying victimization, borderline personality feature (BPF), psychache, depression, and sleep problems were significant risk factors for PLEs. Furthermore, these risk factors demonstrated a cumulative effect on the development of PLEs across time. Additionally, no significant sex differences were observed in the cumulative risk model of PLEs. These findings provide valuable insights into the identification of at-risk adolescents and contribute to the effective implementation of comprehensive preventive measures and interventions targeting PLEs among rural adolescents.

A systematic review of studies using network analysis to assess dynamics of psychotic-like experiences in community samples

Several studies have used a network analysis to recognize the dynamics and determinants of psychotic-like experiences (PLEs) in community samples. Their synthesis has not been provided so far. A systematic review of studies using a network analysis to assess the dynamics of PLEs in community samples was performed. Altogether, 27 studies were included. The overall percentage ranks of centrality metrics for PLEs were 23.5% for strength (20 studies), 26.0% for betweenness (5 studies), 29.7% for closeness (6 studies), 26.9% for expected influence (7 studies), and 29.1% for bridge expected influence (3 studies). Included studies covered three topics: phenomenology of PLEs and associated symptom domains (14 studies), exposure to stress and PLEs (7 studies), and PLEs with respect to suicide-related outcomes (6 studies). Several other symptom domains were directly connected to PLEs. A total of 6 studies investigated PLEs with respect to childhood trauma (CT) history. These studies demonstrated that PLEs are directly connected to CT history (4 studies) or a cumulative measure of environmental exposures (1 study). Moreover, CT was found to moderate the association of PLEs with other symptom domains (1 study). Two studies that revealed direct connections of CT with PLEs also found potential mediating effects of cognitive biases and general psychopathology. PLEs were also directly connected to suicide-related outcomes across all studies included within this topic. The findings imply that PLEs are transdiagnostic phenomena that do not represent the most central domain of psychopathology in community samples. Their occurrence might be associated with CT and suicide risk.

A Digital Approach for Addressing Suicidal Ideation and Behaviors in Youth Mental Health Services: Observational Study

BACKGROUND

Long wait times for mental health treatments may cause delays in early detection and management of suicidal ideation and behaviors, which are crucial for effective mental health care and suicide prevention. The use of digital technology is a potential solution for prompt identification of youth with high suicidality.

OBJECTIVE

The primary aim of this study was to evaluate the use of a digital suicidality notification system designed to detect and respond to suicidal needs in youth mental health services. Second, the study aimed to characterize young people at different levels of suicidal ideation and behaviors.

METHODS

Young people aged between 16 and 25 years completed multidimensional assessments using a digital platform, collecting demographic, clinical, social, functional, and suicidality information. When the suicidality score exceeded a predetermined threshold, established based on clinical expertise and service policies, a rule-based algorithm configured within the platform immediately generated an alert for treating clinicians. Subsequent clinical actions and response times were analyzed.

RESULTS

A total of 2021 individuals participated, of whom 266 (11%) triggered one or more high suicidal ideation and behaviors notification. Of the 292 notifications generated, 76% (222/292) were resolved, with a median response time of 1.9 (range 0-50.8) days. Clinical actions initiated to address suicidality included creating safety plans (60%, 134/222), conducting safety checks (18%, 39/222), psychological therapy (8%, 17/222), transfer to another service (3%, 8/222), and scheduling of new appointments (2%, 4/222). Young people with high levels of suicidality were more likely to present with more severe and comorbid symptoms, including low engagement in work or education, heterogenous psychopathology, substance misuse, and recurrent illness.

CONCLUSIONS

The digital suicidality notification system facilitated prompt clinical actions by alerting clinicians to high levels of suicidal ideation and behaviors detected among youth. Further, the multidimensional assessment revealed complex and comorbid symptoms exhibited in youth with high suicidality. By expediting and personalizing care for those displaying elevated suicidality, the digital notification system can play a pivotal role in preventing rapid symptom progression and its detrimental impacts on young people's mental health.

A longitudinal network of psychotic-like experiences, depressive and anxiety symptoms, and adverse life events: a cohort study of 3,358 college students

AIMS

Psychotic-like experiences (PLEs), especially for persistent PLEs, are highly predictive of subsequent mental health problems. Hence, it is crucial to explore the psychopathological associations underlying the occurrence and persistence of PLEs. This study aimed to explore the above issues through a longitudinal dynamic network approach among PLEs and psychological and psychosocial factors.

METHODS

A total of 3,358 college students completed two waves of online survey (from Oct 2021 to Oct 2022). Socio-demographic information was collected at baseline, and PLEs, depressive and anxiety symptoms, and adverse life events were assessed in both waves. Cross-lagged panel network analyses were used to establish networks among individuals with baseline PLEs as well as those without.

RESULTS

At baseline, 455(13.5%) students were screened positive for PLEs. Distinct dynamic network structures were revealed among participants with baseline PLEs and those without. While 'psychomotor disturbance' had the strongest connection with PLEs in participants with baseline PLEs, 'suicide/self-harm' was most associated with PLEs in those without. Among all three subtypes of PLEs, bizarre experiences and persecutory ideation were the most affected nodes by other constructs in participants with baseline PLEs and those without, respectively. Additionally, wide interconnections within the PLEs construct existed only among participants without baseline PLEs.

CONCLUSIONS

The study provides time-variant associations between PLEs and depressive symptoms, anxiety symptoms, and adverse life events using network structures. These findings help to reveal the crucial markers of the occurrence and persistence of PLEs, and shed high light on future intervention aimed to prevent and relieve PLEs.

Psychotic Experiences and Risk of Suicidal Thoughts and Behaviors: A Systematic Review and Meta-Analysis of Longitudinal Population Studies

BACKGROUND AND HYPOTHESIS

Since a prior systematic review and meta-analysis reported an association between psychotic experiences (PEs) and suicidal thoughts and behaviors, a large number of new studies have been published on the topic, including several novel studies on the association between PEs and transition from suicidal ideation to attempt.

STUDY DESIGN

Two authors independently searched PubMed, Embase, CINAHL, and PsycINFO databases from inception until July 2023, conducted data extraction, and assessed study quality using the Newcastle-Ottawa Quality Assessment Scale. Random-effects models were used to calculate pooled odds ratios (ORs) for the association of PEs and subsequent suicide ideation, suicide attempts, suicide death, and transition from suicidal ideation to attempt, first for the total population, and second stratified by age group. Secondary analyses assessed the mediating role of co-occurring psychopathology.

STUDY RESULTS

Twenty studies from 18 different samples (n = 81,861) were identified. Individuals who reported PEs had increased odds of subsequent suicidal ideation (k = 12, OR = 1.90, 95% CI = 1.65-2.19), suicide attempt (k = 13, OR = 2.95, 95% CI = 2.21-3.94), transition from suicidal ideation to suicide attempt (k = 3, OR = 2.83, 95% CI = 1.60-4.99), and suicide death (k = 1, OR = 4.39, 95% CI = 1.63-11.80). This heightened risk was stable across childhood, adolescence, and adulthood. PEs predicted suicide attempts over and above co-occurring psychopathology (k = 8, OR = 2.85, 95% CI = 2.06-3.95).

CONCLUSIONS

Individuals reporting PEs are at increased risk of all types of suicidal thoughts and behaviors. In addition, PEs are particularly important risk markers for future suicidal behaviors, including in individuals already reporting suicidal ideation. This risk is in excess of what is explained by co-occurring psychopathology.

Current Psychotic-Like Experiences Among Chinese College Students: Prevalence, Correlates, and Its Relationship with Suicidal Ideation

Background

Current psychotic-like experiences (PLEs) are prevalent among adolescents. However, epidemiological data on the prevalence rate of current PLEs among college students and its clinical correlates are scarce and limited. To address this study gap, this study aimed to investigate the prevalence and correlates of current PLEs among Chinese college students.

Methods

A cross-sectional study was designed with a sample of 18,578 college students in China. Each participant completed a survey on social-demographic characteristics variables, PLEs, sleep disturbance, depression, anxiety, and suicidal ideation. Logistic regression analyses were conducted to explore the influential factors for PLEs among all participants and suicidal ideation among those with PLEs.

Results

Among Chinese college students, 40.3% of the participants reported having at least one PLE in the past month, while 7.5% had frequent PLEs. Males, age, residence location in town, left-behind experiences, poor family economic status, chronic physical illness, family history of mental disorder, BMI ≥ 28 [obesity], sleep disturbance, depression, anxiety, and suicidal ideation were independent correlates for frequent PLEs. Furthermore, the prevalence of suicidal ideation among participants with frequent PLEs was 32.1%. Lower grades, sleep disturbance, depression, and anxiety were independent predictors of suicidal ideation among college students who experience PLEs frequently.

Conclusion

Current PLEs are widespread among Chinese college students. Suicidal ideation is largely prevalent among individuals who suffer frequent PLEs, suggesting that special measures and attention should be provided to these students based on relevant factors to prevent their suicidal ideation and behavior.
