Understanding the Pathways from Depression to Suicidal Risk from the Perspective of the Interpersonal-Psychological Theory of Suicide

Childhood maltreatment, peer victimization, borderline personality feature, suicidal risk in adolescents: Direct and indirect associations among developmental trajectories

INTRODUCTION

Childhood maltreatment, peer victimization, and borderline personality traits have all been shown to be linked to suicidal risk. However, there remains a need to illuminate the possible direct and indirect pathways among them from a developmental perspective that could serve as intervention targets. This study thus aimed to investigate the direct and indirect relationships among developmental trajectories of childhood maltreatment, peer victimization, borderline personality feature, and suicidal risk in adolescents.

METHODS

A total of 1648 Chinese adolescents (48.12% boys; Mage = 13.69; SD = 0.82) in junior middle schools completed self-report measures on three-time points across 1 year. Latent growth curve modeling was used to evaluate the direct and indirect relationships among the developmental trajectories of the aforementioned study variables.

RESULTS

The developmental trajectories of childhood maltreatment, peer victimization, and borderline personality feature were positively and directly related to the developmental trajectory of suicidal risk; and the developmental trajectories of childhood maltreatment, peer victimization were indirectly related to the developmental trajectory of suicidal risk through the mediating effect of the developmental trajectory of borderline personality feature.

CONCLUSIONS

The findings elucidated the direct and indirect longitudinal relationships among childhood maltreatment, peer victimization, borderline personality feature, and suicidal risk, highlighting that interventions should target childhood maltreatment, peer victimization, and borderline personality feature to decrease suicidal risk in adolescents with a developmental perspective.

Testing the interpersonal theory of suicide in adolescents: A multi-wave longitudinal study

BACKGROUND

Suicide is a major public health crisis among youth. Several prominent theories, including the Interpersonal Theory of Suicide (IPTS), aim to characterize the factors leading from suicide ideation to action. These theories are largely based on findings in adults and require testing and elaboration in adolescents.

METHODS

Data were examined from high-risk 13-18-year-old adolescents (N = 167) participating in a multi-wave, longitudinal study; 63% of the sample exhibited current suicidal thoughts or recent behaviors (n = 105). The study included a 6-month follow-up period with clinical interviews and self-report measures at each of the four assessments as well as weekly smartphone-based assessments of suicidal thoughts and behaviors. Regression and structural equation models were used to probe hypotheses related to the core tenets of the IPTS.

RESULTS

Feelings of perceived burdensomeness were associated with more severe self-reported suicidal ideation (b = 0.58, t(158) = 7.64, p < .001). Similarly, burdensomeness was associated with more frequent ideation based on weekly smartphone ratings (b = 0.11, t(1460) = 3.41, p < .001). Contrary to IPTS hypotheses, neither feelings of thwarted belongingness, nor interactions between burdensomeness and thwarted belongingness were significantly associated with ideation (ps > .05). Only elevated depression severity was associated with greater odds of suicide events (i.e., suicide attempts, psychiatric hospitalizations, and/or emergency department visits for suicide concerns) during the follow-up period (OR = 1.83, t(158) = 2.44, p = .01). No effect of acquired capability was found.

CONCLUSIONS

Perceptions of burdensomeness to others reflect a critical risk factor for suicidal ideation among high-risk adolescents. Null findings with other IPTS constructs may suggest a need to adopt more developmentally sensitive models or measures of interpersonal and acquired capability risk factors for youth. Refining methods and theoretical models of suicide risk may help improve the identification of high-risk cases and inform clinical intervention.

Examining bidirectional relations between sleep problems and non-suicidal self-injury/suicidal behavior in adolescents: emotion regulation difficulties and externalizing problems as mediators

Based on previous empirical evidences and theoretical framework, sleep problems and non-suicidal self-injury (NSSI)/suicidal behavior may bidirectionally related to one another. However, this still needs to be examined through longitudinal research. Moreover, the mediating mechanisms accounting for their potential bidirectional relations have yet to be fully investigated. This study thus aimed to evaluate whether sleep problems and NSSI/suicidal behavior promoted each other directly or indirectly through the mediating roles of emotion regulation difficulties (ERD) and externalizing problems. A total of 1648 Chinese adolescents (48.12% boys; Mage = 13.69; SD = 0.82; Age range = 11-16 years old at T1) completed self-report measures on 3-time points across 1 year. Cross-lagged panel models were used to examine the focal longitudinal associations. Results revealed a predictive effect of sleep problems on NSSI and a positive bidirectional relation between sleep problems and suicidal behavior. Moreover, sleep problems exerted an indirect effect on NSSI through ERD, and vice versa. Additionally, both ERD and externalizing problems served as mediators in the pathway from suicidal behavior to sleep problems. This study disentangled the differential mediating roles of ERD and externalizing problems in the longitudinal associations between sleep problems and NSSI/suicidal behavior, which may help provide a more holistic theoretical framework through which to precisely identify key targets for early prevention and intervention of sleep problems and NSSI/suicidal behavior in adolescents.

The Influence of Social Exclusion on High School Students' Depression: A Moderated Mediation Model

Purpose

High school students face various pressures such as academic and interpersonal relationships, which can easily lead to depression. Social exclusion is one of the important influencing factors for adolescent depression, but there is still limited research on the mechanisms of the impact that social exclusion has on depression. Therefore, this study aimed to explore the effect of social exclusion on depression among high school students, as well as the mediating role of thwarted belongingness and the moderating role of cognitive reappraisal.

Methods

Researchers assessed 1041 high school students using the Center for Epidemiologic Studies Depression Scale (CES-D), Adolescent Social Exclusion Scale, Interpersonal Needs Scale, and Emotion Regulation Scale.

Results

(1) Social exclusion was negatively associated with cognitive reappraisal (r = -0.224, p < 0.001), and positively associated with thwarted belongingness and depression (r = 0.657, 0.490, p <0.001). Thwarted belongingness was positively associated with depression (r = 0.617, p <0.001), and negatively associated with cognitive reappraisal (r = -0.325, p <0.001). Cognitive reappraisal was negatively associated with depression (r = -0.280, p < 0.01). (2) Social exclusion could directly predict depression, 95% CI [0.08, 0.21]. Thwarted belongingness played a partial mediating role between social exclusion and depression, 95% CI [0.30, 0.40]. (3) Cognitive reappraisal moderated the predictive effect of thwarted belongingness on depression.

Conclusion

Social exclusion can influence depression through thwarted belongingness and cognitive reappraisal, and educators can reduce depression by decreasing thwarted belongingness and promoting the use of cognitive reappraisal strategies by high school students.

Profiles, Transitions, and Resilience Factors of Suicide Risk in Early Chinese Adolescents

As a severe public health concern directly endangering life safety, adolescent suicide has been extensively investigated in variable-centered studies. However, gaps remain in the knowledge of heterogeneous suicide risk patterns and their developmental nature. Additionally, little is known about protective factors associated with suicide risk patterns and changes. This study applied person-centered approaches to explore suicide risk profiles and transitions over time in early Chinese adolescents, along with their protective factors. A total of 1518 junior high school students (49.6% girls, Mage = 13.57, SD = 0.75) participated in two surveys within a 12-month interval. Latent Profile Analysis and Latent Transition Analysis were used to model the profiles and transitions of suicide risk. Three risk profiles were identified at both time points: low risk profile (73.9, 78.3%), medium risk-high threat profile (16.2, 10.2%), and high risk profile (9.9, 10.2%). Low risk profile was stable, while medium risk-high threat and high risk profiles showed great transitions over 12 months. Sense of control, meaning in life, and regulatory emotional self-efficacy served as protective factors against suicide risk profiles and transitions. Findings underscore the importance of comprehensively illustrating suicide risk states from multiple aspects, as well as understanding the fluid nature of transitions between different risk states. Prevention and intervention strategies aimed at enhancing resilience, such as increasing sense of control, perceived meaningfulness, and belief in emotional regulation, may contribute to reducing the risk of suicide among adolescents.

Effects of school environment on depression among Black and White adolescents

While the school environment is critical for adolescents' psychological development, how the school environment influences depression among different racial groups has not been fully explored. This study aims to identify the effects of the school environment (school connectedness, school climates, trouble with peers and teachers) on depressive symptoms among Black and White adolescents. It also compares how the effects of school environments differ between Black and White adolescents. This study analyzed wave 6 of the Fragile Families and Child Well-being Study, a longitudinal birth cohort study in 20 major cities across the United States. Almost three-fourth (73.39%) of the adolescents were Black, and 26.61% were White. About half (50.46%) of the adolescents were females, and the mean age of adolescents was 15.39. Multiple regression analysis showed that higher school connectedness and less frequent troubles with teachers were associated with lower depression among Black adolescents. In contrast, only school connectedness was associated with depression among White adolescents. Higher school connectedness was associated with lower depressive symptoms for both Black and White adolescents. However, the magnitude of the effects of school connectedness was found to be statistically weaker among Black adolescents. These findings suggest a need for creating a racially equitable school environment that makes every student feel more connected to their schools, especially Black students.

Internet addiction and suicidal behavior among vocational high school students in Hunan Province, China: A moderated mediation model

Background

Vocational education is an important part of high school education in China. However, there is little research on high school students' mental health. This study aimed to investigate the prevalence of suicidal behavior (SB) among this population and the mediating role of insomnia, depression, anxiety, and stress in the relationship between Internet addiction (IA) and SB using a structural equation model.

Methods

A cross-sectional questionnaire survey was conducted among several vocational high school students in Hunan Province, and 7,968 valid questionnaires were obtained. General demographic data and data from the Dual-Mode Self-Control Scale, Athens Insomnia Scale, Depression Anxiety Stress scale-21, and Revised Chen Internet Addiction Scale were collected. A structural equation model was used to explore the different pathways from IA to SB.

Results

Among the participants, 37.7, 15.7, and 21.8% reported suicidal ideation, plans, and attempts, respectively. The structural equation model confirmed that IA was indirectly related to SB and was mediated by insomnia and/or depression, anxiety, and stress.

Limitations

First, we only recruited students from vocational schools in Hunan Province, therefore, the sample may not represent the entire population of vocational students in China. Second, self-report scales were used in this study, and clinical diagnosis required professional interviews. Third, since this study had a cross-sectional design, the causal relationship between the variables could not be determined.

Conclusions

The prevalence of SB among vocational high school students in China was significantly high. The prevention of SB related to IA can be attributed to the improvement of insomnia and emotional problems.

Integrating the Interpersonal Theory of Suicide Into the Relations Between Cyber-Victimization and Suicidality Among Adolescents: A Short-Term Prospective Study

The relation between cyber-victimization and suicidality among adolescents has been well documented; however, the mechanisms underlying this association have not been well investigated. Drawing upon the interpersonal theory of suicide, this study aimed to examine the mediating mechanisms (i.e., thwarted belongingness and perceived burdensomeness) underlying longitudinal, bidirectional relations between cyber-victimization and suicidal ideation/attempts among adolescents and explore gender differences in the mechanisms. Participants were 497 Chinese adolescents (46.1% male; M_age = 13.28, SD = .66), who completed the assessment of cyber-victimization, thwarted belongingness, and perceived burdensomeness, suicidal ideation/attempts at three-time points. The time interval between each two assessments is two weeks. Results showed the reciprocal relations between cyber-victimization and thwarted belongingness/perceived burdensomeness, between thwarted belongingness and suicidal ideation/suicide attempts, and between perceived burdensomeness and suicide attempts. Longitudinal mediation analyses indicated that Time 2 thwarted belongingness mediated the relation between Time 1 cyber-victimization and Time 3 suicidal ideation/suicide attempts. Besides, the reverse pathway from Time 1 suicidal ideation to Time 3 cyber-victimization was also mediated by Time 2 thwarted belongingness, but it was only significant in females, as suggested by multiple-group analyses. According to the aforementioned results, the interpersonal theory of suicide provides a useful framework for understanding relations between cyber-victimization and suicidality. Findings suggest that intervention targeted at improving the need to belong may help reduce suicide risk and lower cyber-victimization. Anti-cyber-victimization should be integrated into suicide intervention and prevention programs, and gender differences should be taken into account in order to enhance the program's effectiveness.

Suicidal ideation and suicide attempts among university students in South Korea during the COVID-19 pandemic: the application of interpersonal-psychological theory and early maladaptive schema

Background

This study examined the application of interpersonal-psychological theory and early maladaptive schema of suicidal ideation and suicide attempts in South Korean university students.

Methods

In this cross-sectional study, data from 367 university students were surveyed using the Interpersonal Needs Questionnaire, Early Maladaptive Schema, Suicide Ideation Scale, and the Acquired Capability for Suicide Scale. Data were collected between June 21 and July 21, 2021.

Results

University students' interpersonal needs and early maladaptive schema were significantly associated with suicidal ideation, and influencing suicide attempts. The acquired capability for suicide moderated the relationship between suicidal ideation and attempts.

Conclusions

In suicide prevention programs for university students, it is critical to consider their interpersonal needs and early maladaptive schema, and the acquired capability for suicide, to prevent suicidal ideation and attempts among them.

Depressive rumination and life satisfaction among institution-dwelling Chinese older adults: the roles of perceived burdensomeness and social support from individuals within the institution

Objectives: We examined how institution-dwelling older adults' depressive rumination was associated with their life satisfaction by taking perceived burdensomeness as a mediator and social support from individuals within the institution (SSII) as a moderator.Method: A total of 194 older adults from 24 institutions in four provinces of China completed a questionnaire survey.Results: Depressive rumination was negatively associated with life satisfaction, and perceived burdensomeness mediated this association. Moreover, SSII moderated the indirect association between depressive rumination and life satisfaction through perceived burdensomeness. Specifically, depressive rumination had a negative effect on life satisfaction through perceived burdensomeness only for older adults with less SSII.Conclusion: Our study indicated that depressive rumination could damage older adults' life satisfaction by increasing their perceived burdensomeness. Fortunately, older adults' perception of social support from individuals within the institution could attenuate this negative effect. This study has implications for designing intervention programs to improve the institution-dwelling older adults' life satisfaction.

The relationship between internalizing problems and acute exercise duration in children with attention-deficit/hyperactivity disorder: The role of frontal alpha asymmetry

BACKGROUND

Frontal alpha asymmetry (FAA) has been associated with the regulation of certain types of internalizing psychopathologies, and is affected by acute aerobic exercise (AE). However, no previous studies have examined the association between FAA and internalizing problems or the effects of acute exercise on FAA in children with ADHD.

AIMS

This study had two objectives. First, it aimed to examine the relationship between FAA and internalizing behaviors in children with ADHD. Second, it sought to investigate the differential effects of acute AE (30 and 50 min) on FAA.

METHOD

Participants were assigned to one of the following three groups: 50 min of AE, 30 min of AE, and a control group. Resting electroencephalogram (EEG) data were recorded before and after their respective treatments. EEG data from 43 participants were analyzed to investigate the association between pre-test FAA and internalizing problems as assessed by Child Behavior Checklist scores. Additionally, EEG data from 46 participants were analyzed to examine the effects of acute AE on post-test FAA while controlling for pre-test FAA.

RESULTS

Pre-test FAA was found to be significantly negatively associated with internalizing problems, with both hemispheres contributing to this association. Regarding the effects of acute exercise, the 50-minute AE group had highest post-test FAA, reflected by the increased relative left-side frontal activity.

CONCLUSIONS

These findings suggest that FAA is a biological marker of internalizing symptoms in children with ADHD, and a 50-minute session of AE can effectively modulate FAA.

Serial multiple mediation of the association between internet gaming disorder and suicidal ideation by insomnia and depression in adolescents in Shanghai, China

BACKGROUND

High prevalence and strong relationships among suicidal ideation, Internet gaming disorder (IGD), insomnia, and depression have been reported for adolescents worldwide, but the mechanism underlying these psychological problems remains unclear. This cross-sectional study explored the mediating effect of insomnia and depression on the association between IGD and suicidal ideation.

METHODS

Participants were 1066 adolescents (median age = 13.0 years) with Internet games exposure in the previous 12 months from junior high schools in Shanghai, China. Questionnaire measures of suicidal ideation, IGD, insomnia, depressive symptoms, and background characteristics were obtained. Path analysis was conducted to test the multiple mediating roles of insomnia and depression.

RESULTS

Suicidal ideation, IGD, insomnia, and depression prevalence was 27.2, 13.6, 9.2, and 17.0%, respectively. A serial multiple mediation model was generated. The mediation effect of insomnia and depression on the pathway from IGD to suicidal ideation was 45.5% (direct effect: standardized estimate [Std. estimate] = 0.186; total indirect effect: Std. estimate = 0.155). The association between IGD and depression was partially mediated by insomnia (direct effect: Std. estimate = 0.211; indirect effect: Std. estimate = 0.135). The proposed model fit the data well.

CONCLUSIONS

Insomnia and depression may serially mediate the association between IGD and suicidal ideation. IGD was positively associated with insomnia, then with depression, which in turn positively contributed to suicidal ideation. We suggest greater monitoring of Internet use and prevention of insomnia and depression to mitigate the risk of suicidal ideation among Chinese adolescents.

Does early peer relationship last long? The enduring influence of early peer relationship on depression in middle and later life

BACKGROUND

Previous studies focus on the health effect of early family relationship rather than early peer relationship. Thus, this study aimed to examine the causal effect of early peer relationship on depression in middle and later life.

METHODS

Based on the China Health and Retirement Longitudinal Study data 2013-2014 (N = 15,343), this study used the propensity score matching approach to estimate the causal effect of early peer relationship, including establishment (whether having good friends in childhood), engagement (frequency of playing with friends in childhood) and feeling (feeling of loneliness in childhood), on depression in middle and later life, as well as the educational heterogeneity of this health effect.

RESULTS

Elevated feeling of loneliness and reduced engagement of early peer relationship were causally related to elevated depression in middle and later life, but having good friends in childhood was not related to later life depression. For individuals with more education, less feeling of loneliness in childhood had a stronger effect on reduced depression in middle and later life, but more engagement in childhood peer relationship only had a weaker effect on reduced depression in middle and later life.

LIMITATIONS

A retrospective survey and single-item measures of early peer relationship were used, the intermediate link across the life course and potential neurobiological mechanisms were also not empirically examined.

CONCLUSIONS

We should focus more on the engagement and quality of early peer relationship, as well as the balance between education and socializing in childhood, to prevent from the detrimental health effect of early peer relationship disadvantage.

The Prevalence and Correlates of Suicidality in a Sample of Adolescents in Guangdong, China

Background: Suicidality is a public health concern among Chinese adolescents. This study aimed to examine the prevalence and correlates of suicidal ideation and suicide attempts in a large sample of Chinese adolescents.

Methods: A total of 30,644 Chinese students (56.7% male; Mage = 14.14 years) completed the questionnaires, and a multinomial logistic regression was conducted to analyze the data.

Results: About 17.0% of the participants reported having suicidal ideation and 4.4% reported suicide attempts in the past year. Adolescents with more rumination, more severe depressive symptoms, more communication problems with their parents, and more feelings of burdensomeness were more likely to be suicidal ideators or suicide attempters rather than non-suicidal controls. Additionally, male adolescents, adolescents from incomplete families, adolescents whose parents have lower educational levels, and adolescents with less rumination, more severe depressive symptoms, less communication problems with their parents were more likely to be suicide attempters rather than suicidal ideators.

Discussion: Suicidality is prevalent and correlates with various familial and individual factors in Chinese adolescents. Theoretical and clinical implications of the findings were discussed.

Suicide Attempt and Suicidal Drug Overdose in Chronic Obstructive Pulmonary Disease Patients With or Without Depression

BACKGROUND

To determine differences in the incidence and risks of suicide attempt (SA) and suicidal drug overdose (SDO) between chronic obstructive pulmonary disease (COPD) patients with and without comorbid depression by using data from Taiwan's National Health Insurance Research Database.

METHODS

We analyzed the data of patients aged ≥20 years who had received a COPD diagnosis between 2000 and 2012. These COPD patients were divided into those with and without depression, and they were compared against a cohort from the general population. We calculated adjusted hazard ratios and the corresponding 95% confidence intervals for SA and SDO in the three cohorts after adjustment for age, sex, and comorbidities.

RESULTS

Until the end of 2012, 5.81% of patients with COPD developed depression. The incidence of SA and SDO in COPD patients with and without depression was 29.7 and 4.69 per 10,000 person-years and 71.2 and 20.9 per 10,000 person-years, respectively. COPD patients with depression had 13.6- and 10.0-fold higher risks of SA and SDO, respectively, than did controls. Particularly, an increased risk of SA caused by the enhancement effects of depression on COPD was noted in patients aged less than 50 years.

CONCLUSION

SA and SDO risks are extremely high in Taiwanese COPD patients with depression. Our findings suggest that clinicians should be aware that for COPD patients with comorbid depression, prescribing a large amount of medications may be associated with SA risk through SDO.
