Psychosocial characteristics of adolescents with a history of suicide attempt

The effect of parent-adolescent discrepancies in reports of familial dysfunction and depression on suicidal ideation in adolescents

INTRODUCTION

Parents and adolescents are often discrepant in their reports of adolescent psychosocial factors. Few studies have addressed parent-adolescent discrepancies in subjective ratings of familial dysfunction and depression as longitudinal predictor variables, and none have done so in a treatment setting for adolescents with acute suicidality. This study examined how parent-adolescent discrepancies in familial dysfunction and depression impact adolescent treatment response in an intensive outpatient program for suicidality.

METHODS

Adolescents (N = 315) were assessed at treatment entry and exit for familial dysfunction, depression, and suicidal ideation. Parents received parallel assessments of familial dysfunction and adolescent depression at each time point. A polynomial regression was conducted to determine whether parent-adolescent discrepancies in reports of familial dysfunction and depression at entry related to the treatment outcome of adolescent-reported depression and suicide ideation at exit.

RESULTS

Significant discrepancies were present with on average adolescents reporting more depression and familial dysfunction than parents. Entry discrepancy in familial dysfunction (but not depression) predicted suicide ideation at exit.

CONCLUSIONS

Our results suggest that parent-adolescent discrepancies in perception of familial dysfunction is a risk factor for poor outcomes in suicidal youth and might be a fruitful target in treatment programs.

The Moderating Effect of Body Appreciation on the Relationship between Self-Esteem and Life Satisfaction

BACKGROUND

Although positive associations between life satisfaction, self-esteem, and body image have previously been established, differences in these variables by gender and age have yielded mixed results. Moreover, little is known about the interplay between self-esteem and body appreciation on life satisfaction. This study aims to investigate the moderating effect of body appreciation on the relationship between self-esteem and life satisfaction, considering disparities between females and males and also between emerging adults (before the age of thirty) and older adults.

METHODS

A cross-sectional online survey was performed in Poland with a sample of 449 adults aged between 18 and 75 (M = 30.41, SD = 12.72), including 68% of women. The survey included the Satisfaction With Life Scale (SWLS), Rosenberg Self-Esteem Scale (RSES), and Body Appreciation Scale (BAS-2).

RESULTS

Men scored higher than women in terms of life satisfaction and self-esteem, while older participants (age > 30) scored higher than younger individuals (age ≤ 30) in terms of life satisfaction, self-esteem, and body appreciation. The study confirmed positive and moderate correlations between life satisfaction, self-esteem, and body appreciation. The interactive effect of self-esteem and body appreciation on life satisfaction was also found by controlling for age and gender.

CONCLUSIONS

Some intervention programs focused on increasing levels of self-esteem and body appreciation should be implemented, especially among women and emerging adults, to improve their well-being.

A Comparative Analysis of Depressive Symptoms Following Sports-Related Concussion in Youth Athletes Versus Their Age-Matched Non-concussed Counterparts

Background and objective

Athletics is the leading cause of pediatric concussion, and depression is a major comorbidity associated with concussion in the pediatric population. Prior studies have described the risk of depression after concussion in high school-, collegiate-, and elite-level athletes, but there is scarce data on younger athletes. Interpretation of existing research on the association of depression with concussions in youth athletes is complicated by diverse study designs, varying measures of depression, differing timelines for symptom development, and a lack of control groups. Furthermore, limited research exists on sex-related differences in the development of depressive symptoms following sports-related concussions (SRC) in younger athletes. This study used the Seattle Pediatric Concussion Research Collaborative (SPCRC) Data Repository to compare depressive symptoms between youth athletes at one month post-SRC and non-concussed age-matched controls by using a standardized measure of depressive symptoms: the Patient Health Questionnaire-9 (PHQ-9). The secondary goal was to compare PHQ-9 scores between males and females for both concussed and non-concussed groups.

Methods

This study entailed a secondary analysis of data collected as part of the SPCRC Data Repository. We conducted a retrospective subgroup analysis of PHQ-9 scores at one month post-concussion for concussed youth athletes. We compared the PHQ9 scores of concussed youth athletes with PHQ-9 scores collected at the time of enrollment for non-concussed youth athletes.

Results

After random age-matching, a cohort of 266 patients (133 in the concussed group and 133 in the non-concussed control group) was included in the final analysis. The mean age was 13.8 years (range: 5-18 years). For the concussed group, a history of SRC was associated with a higher mean total PHQ-9 score at one month post-concussion compared with the control group at the time of enrollment (6.14 ±5.46 versus 1.53 ±1.81, respectively, p<0.0001). All nine subdomains of the PHQ-9 showed significantly higher scores in the concussion group compared with the control group (p<0.0001). Significantly higher scores were observed when comparing mean total PHQ-9 scores for male athletes in the concussion group with male athletes in the control group (7.03 ±5.72 versus 1.59 ±1.66, p<0.0001) and for female athletes in the concussion group compared with female controls (5.28 ±5.10 versus 1.49 ±1.92, p<0.0001). No significant differences were observed between sexes for total PHQ-9 scores or PHQ-9 subscores.

Conclusion

At one month post concussion, youth with SRC demonstrated higher levels of depressive symptoms as measured by PHQ-9 compared with age-matched typically developing controls. No significant differences were identified in total PHQ-9 scores and subscores between male and female participants for either the concussion or control group. This study suggests that clinicians need to be vigilant and monitor for symptoms of depression in young athletes for at least one month post-concussion.

Exploration of the Moderating Effects of Physical Activity and Early Life Stress on the Relation between Brain-Derived Neurotrophic Factor (BDNF) rs6265 Variants and Depressive Symptoms among Adolescents

Depression affects one in five persons at 18 years of age. Allele A of the brain-derived neurotrophic factor (BDNF) rs6265 is considered to be a risk factor for depression. Previous studies of the interaction between BDNF rs6265, early adversity, and/or physical activity have shown mixed results. In this study, we explored the relation between BDNF rs6265 polymorphism and childhood stress, as well as the moderating effect of physical activity in relation to depressive symptoms using binary logistic regressions and process models 1, 2 and 3 applied to data obtained at three times (waves 1, 2 and 3) from the Survey of Adolescent Life in Västmanland cohort study (SALVe). Results revealed that both childhood stress and physical activity had a moderation effect; physical activity in wave 1 with an R2 change = 0.006, p = 0.013, and the Johnson−Neyman regions of significance (RoS) below 1.259, p = 0.05 for 11.97%; childhood stress in wave 2 with the R2 change = 0.008, p = 0 002, and RoS below 1.561 with 26.71% and >4.515 with 18.20%; and a three-way interaction in wave 1 in genotype AA carriers. These results suggest that allele A is susceptible to physical activity (positive environment) and childhood stress (negative environment).

Family and peer support moderates the relationship between distress tolerance and suicide risk in black college students

ObjectivesThe relationship between distress tolerance and suicide risk was examined in black college students, as well as the moderating role of family and peer support in this relationship. Parent and peer support were studied separately in their relationship to overall suicidality.MethodOne-hundred twenty-five Black undergraduate students completed self-report measures that assessed study variables.ResultsUsing moderation analyses, distress tolerance was significantly associated with overall suicidality, such that increased tolerance was associated with decreased risk. Higher family support was significantly associated with decreased suicide risk, while peer support was not. However, both family and peer support significantly moderated the relationship between distress tolerance and suicide risk. For both types of support, the relationship between distress tolerance and suicide risk was significant when support was low.ConclusionsSocial support appears to be an important protective factor for suicide risk in black college students.

Resilience among students at risk of dropout: Expanding perspectives on youth suicidality in a non-clinical setting

While research supports a strong association between risk of school dropout and suicidality, this youth population remains understudied. This qualitative study addresses this gap by examining self-reported risk and protective factors among 44 alternative high school students who endorsed varying levels of suicidal ideation. Criterion sampling of Suicidal Ideation Questionnaire-JR scores informed student selection for semi-structured interviews. Students were grouped by low, moderate, or high suicidal ideation scores. Transcribed interviews were analyzed using thematic analysis. The findings demonstrate subgroup differences of suicide risk and resiliency among students at risk of dropout and offer points for prevention and intervention. School practitioners can advocate for school-based suicide preventive interventions that are tailored for students who are both at risk of suicide and academic failure.

Parental internalizing disorder and the developmental trajectory of infant self-regulation: The moderating role of positive parental behaviors

Child self-regulation (SR), a key indicator for later optimal developmental outcomes, may be compromised in the presence of parental mental disorders, especially those characterized by affective dysregulation. However, positive parental behaviors have been shown to buffer against such negative effects, especially during infancy when SR shows great plasticity to environmental inputs. The current study investigated the effect of maternal and paternal lifetime and current internalizing disorders on the developmental trajectory of infant SR from 3 to 24 months, and the potential moderating role of positive parental behaviors. A latent growth model revealed that SR increased overall from 3 to 24 months. Mothers' positive parental behaviors demonstrated significant moderation effects, such that maternal lifetime internalizing disorder was associated with higher SR intercept only among those with low levels of positive parental behavior. Mothers' lifetime internalizing disorder was also associated with a lower linear slope in SR development with a moderate effect size. Fathers' current internalizing disorder was significantly associated with a higher intercept and lower linear slope of the SR trajectory. The current study expands the infant SR literature by describing its early developmental trajectory as well as early risk and protective factors within the parent-infant environment, taking into consideration developmental inputs from both parents.

School absenteeism as a risk factor for self-harm and suicidal ideation in children and adolescents: a systematic review and meta-analysis

Self-harm and suicidal ideation in children and adolescents are common and are risk factors for completed suicide. Social exclusion, which can take many forms, increases the risk of self-harm and suicidal ideation. One important marker of social exclusion in young people is school absenteeism. Whether school absenteeism is associated with these adverse outcomes, and if so to what extent, remains unclear. To determine the association between school absenteeism and both self-harm (including completed suicide) and suicidal ideation in children and adolescents, we conducted a systematic review of observational studies. We conducted meta-analysis and report a narrative synthesis where this was not possible. Meta-analysis of cross-sectional studies showed that school absenteeism was associated with an increased risk of self-harm [pooled adjusted odds ratio (aOR) 1.37, 95% confidence interval 1.20-1.57, P = 0.01] and of suicidal ideation (pooled aOR 1.20, 95% CI 1.02-1.42, P = 0.03). A small number of studies showed that school absenteeism had a longitudinal association with both adverse outcomes. Heterogeneity in the exposure and outcome variables, study design and reporting was prominent and limited the extent to which it was appropriate to pool results. School absenteeism was associated with both self-harm and suicidal ideation in young people, but this evidence was derived from a small number of cross-sectional studies. Further research into the mechanisms of this association could help to inform self-harm and suicide prevention strategies at clinical, school and population levels.

The longitudinal relationship of alcohol problems and depressive symptoms and the impact of externalising symptoms: findings from the Belfast Youth Developmental Study

PURPOSE

The aim of the present study was to contribute to the inconsistent literature on the comorbid relationship of alcohol problems and depressive symptoms from late adolescent to emerging adulthood by accounting for their trajectories and their conjoint relationship while controlling for the influence of externalising symptoms.

METHODS

We utilised data, from a longitudinal school cohort from Northern Ireland (Belfast Youth Developmental Study), over three time points where the participants were 16, 17 and 21 years of age. A total of 3118 participants were included, 1713 females and 1405 males. Second-order latent growth models were applied to examine growth trajectories. Parallel process growth models were used to assess whether growth trajectories of the symptoms were associated. Externalising symptoms were subsequently added as a covariate.

RESULTS

Alcohol problems among males significantly increased over time but decreased in females. Depressive symptoms initially increased then decreased in both genders. Results indicated associations of the alcohol problems and depression, both initially and with time. Accounting for externalising symptoms only somewhat diminished this effect in males but not in females. An increase of initial levels of depression was associated with a decrease in alcohol problems over time. This association was only true among females. After controlling for externalising symptoms, the relationship was no longer observed.

CONCLUSIONS

The present study provides further evidence of a significant relationship of alcohol problems and depression in adolescents and further supports a small literature indicating that depression may have protective effects of alcohol problems. Finally, the study shows the importance of accounting for externalising symptoms.

Motivational Interviewing-Enhanced Safety Planning for Adolescents at High Suicide Risk: A Pilot Randomized Controlled Trial

This pilot randomized controlled trial examined the feasibility and acceptability of a motivational interview (MI)-enhanced safety planning intervention (MI-SafeCope) for teens hospitalized due to suicide risk and explored proximal outcomes (possible mechanisms of change). Participants were 36 hospitalized adolescents (ages 13-17; 78.8% female) with last-week suicidal ideation and/or past-month suicide attempts. Adolescents were randomized to MI-SafeCope, a three-component intervention (individual and family sessions, postdischarge call), or to treatment as usual. Primary outcomes were feasibility and acceptability. We also explored differences in proximal outcomes assessed at 2 weeks, 1 month, and 3 months (family connectedness, motivation for safety plan use, parental motivation to encourage safety plan use), as well as daily for 4 weeks (self-efficacy, coping behavior, safety plan use). Participation and retention rates and intervention satisfaction ratings indicate feasibility and acceptability. Mixed-effects models of daily assessments indicated, for the MI-SafeCope group, significantly higher self-efficacy to refrain from suicidal action (B = 1.15, p = .030), greater reliance on self to cope with suicidal ideation (B = 1.56, p = .042), and higher likelihood of safety plan use to manage suicidal thoughts (B = 0.25, p = .004). Parents in the MI-SafeCope group reported higher motivation to encourage safety plan use (B = 1.04, p = .031). Safety planning incorporating MI is feasible and acceptable with hospitalized teens. Preliminary findings suggest that MI strategies may be promising in maintaining adherence to safety plans, increasing self-efficacy and coping, and in fostering parents' motivation to encourage safety plan use. Our study also highlights the benefit of daily-level assessment of individuals' response to suicide-specific interventions.

Traumatic Brain Injury, Sleep Disorders, and Psychiatric Disorders: An Underrecognized Relationship

Traumatic brain injury (TBI) is commonplace among pediatric patients and has a complex, but intimate relationship with psychiatric disease and disordered sleep. Understanding the factors that influence the risk for the development of TBI in pediatrics is a critical component of beginning to address the consequences of TBI. Features that may increase risk for experiencing TBI sometimes overlap with factors that influence the development of post-concussive syndrome (PCS) and recovery course. Post-concussive syndrome includes physical, psychological, cognitive and sleep-wake dysfunction. The comorbid presence of sleep-wake dysfunction and psychiatric symptoms can lead to a more protracted recovery and deleterious outcomes. Therefore, a multidisciplinary evaluation following TBI is necessary. Treatment is generally symptom specific and mainly based on adult studies. Further research is necessary to enhance diagnostic and therapeutic approaches, as well as improve the understanding of contributing pathophysiology for the shared development of psychiatric disease and sleep-wake dysfunction following TBI.

Parental Self-Efficacy to Support Teens During a Suicidal Crisis and Future Adolescent Emergency Department Visits and Suicide Attempts

This study of adolescents seeking emergency department (ED) services and their parents examined parents' self-efficacy beliefs to engage in suicide prevention activities, whether these beliefs varied based on teens' characteristics, and the extent to which they were associated with adolescents' suicide-related outcomes. Participants included 162 adolescents (57% female, 81.5% Caucasian), ages 13-17, and their parents. At index visit, parents rated their self-efficacy to engage in suicide prevention activities and their expectations regarding their teen's future suicide risk. Adolescents' ED visits for suicide-related concerns and suicide attempts were assessed 4 months later. Parents endorsed high self-efficacy to engage in most suicide prevention activities. At the same time, they endorsed considerable doubt in being able to keep their child safe if the teen has thoughts of suicide and in their child not attempting suicide in the future. Parents whose teens experienced follow-up suicide-related outcomes endorsed, at clinically meaningful effect sizes, lower self-efficacy for recognizing suicide warning signs, for obtaining the teen's commitment to refrain from suicide, and for encouraging their teen to cope, as well as lower confidence that their teen will not attempt suicide; self-efficacy to recognize warning signs was at trend level. Despite endorsing high self-efficacy for the majority of suicide prevention activities, parents of high-risk teens expressed less confidence in their capacity to influence their teen's suicidal behavior, which could undermine parents' effort to implement these strategies. The relationship between parental self-efficacy and youth suicide-related outcomes points to its potential value in guiding clinical decision making and interventions.

Sleep, Affect, and Social Competence from Preschool to Preadolescence: Distinct Pathways to Emotional and Social Adjustment for Boys and for Girls

Using a normative sample of 1,057 children studied across 4 waves over 6 years with multiple informants, we investigated transactional relations for sleep problems, anxious-depressed symptoms, and social functioning from preschool to preadolescence, assessing cumulative effects on children's emotional and social adjustment. To examine sex differences in the developmental processes, we conducted separate analyses for boys and girls. For both boys and girls, longitudinal cross-lagged panel analyses showed that preschool sleep problems directly predicted anxious-depressed symptoms 2 years later; indirect effects continued into preadolescence. For girls, early and later sleep problems directly or indirectly predicted a wide variety of preadolescent emotional and social adjustment domains (e.g., depressive symptoms, school competence, emotion regulation, risk-taking behaviors). For boys, social competence played a more important role than sleep problems in predicting preadolescent adjustment. Among the first set of findings that demonstrate longitudinal relations between sleep problems and social functioning in middle childhood and preadolescence, these results support Dahl's and Walker's neurological models of sleep and emotional functioning. We discuss these findings in light of relations between sleep and affect during pre-pubertal development and discuss differential findings for boys and girls.

Association between HTR1B alleles and suicidal ideation in individuals with major depressive disorder

Serotonin receptors, also known as 5-hydroxytryptamine receptors (HTRs), play a role in individuals' vulnerability to major depressive disorders (MDDs) and/or suicide attempts. In the first part of the study, we recruited 789 Taiwanese participants, which included 285 MDD patients, 191 MDD patients with a history of suicide attempts (MS), and 313 controls. The three groups were genotyped to identify HTR single nucleotide polymorphisms (SNPs) and we analyzed the correlations among the three groups. In the second part of the study, which involved a functional test of HTR1B allelic and haplotype variants, another 113 MDD patients were recruited. The rs6298-T allele was more frequent in the MS group than in the control group. The rs1923885-T allele occurred more frequently in the MS group than in the MDD group. Carriers of haplotype GT were estimated to have a 1.774-fold higher risk of suicide attempts. Younger age, alleles rs6296-C, rs6298-T and rs1923885-C, and haplotype CT were associated with a greater risk of MDD. Haplotypes GC and GT were directly associated with a lower risk of suicidal ideation. Haplotypes GC and GT also associated with higher levels of HTR1B mRNA, and haplotype GC was associated with extraversion, which caused a lower risk of suicidal ideation. The rs6296-C allele have directly and indirectly influenced a greater risk of suicidal ideation, which mediated by its negative effect on extraversion. Haplotype GT can be used to identify patients with a higher risk of suicide attempts. The rs6296-C allele lowered the level of HTR1B mRNA, causing individuals with MDD to display more hostility and aggressive behavior, which may lead to suicidal ideation.

Response Inhibition, Peer Preference and Victimization, and Self-Harm: Longitudinal Associations in Young Adult Women with and without ADHD

Self-harm (suicidal ideation and attempts; non-suicidal self-injuries behavior) peaks in adolescence and early-adulthood, with rates higher for women than men. Young women with childhood psychiatric diagnoses appear to be at particular risk, yet more remains to be learned about the key predictors or mediators of self-harm outcomes. Our aims were to examine, with respect to self-harm-related outcomes in early adulthood, the predictive validity of childhood response inhibition, a cardinal trait of attention-deficit hyperactivity disorder (ADHD), as well as the potential mediating effects of social preference and peer victimization, ascertained in early adolescence. Participants were an ethnically and socioeconomically diverse sample of 228 girls with and without ADHD, an enriched sample for deficits in response inhibition. Childhood response inhibition (RI) predicted young-adult suicide ideation (SI), suicide attempts (SA), and non-suicidal self-injury (NSSI), over and above full-scale IQ, mother's education, household income, and age. Importantly, teacher-rated social preference in adolescence was a partial mediator of the RI-SI/SA linkages; self-reported peer victimization in adolescence emerged as a significant partial mediator of the RI-NSSI linkage. We discuss implications for conceptual models of self-harm and for needed clinical services designed to detect and reduce self-harm.

The Effects of Mindfulness-Based Cognitive Therapy and Cognitive Behavioral Analysis System of Psychotherapy added to Treatment as Usual on suicidal ideation in chronic depression: Results of a randomized-clinical trial

BACKGROUND

Suicidal ideation (SI) is common in chronic depression, but only limited evidence exists for the assumption that psychological treatments for depression are effective for reducing SI.

METHODS

In the present study, the effects of Mindfulness-based Cognitive Therapy (MBCT; group version) plus treatment-as-usual (TAU: individual treatment by either a psychiatrist or a licensed psychotherapist, including medication when indicated) and Cognitive Behavioral Analysis System of Psychotherapy (CBASP; group version) plus TAU on SI was compared to TAU alone in a prospective, bi-center, randomized controlled trial. The sample consisted of 106 outpatients with chronic depression.

RESULTS

Multivariate regression analyses revealed different results, depending on whether SI was assessed via self-report (Beck Depression Inventory suicide item) or via clinician rating (Hamilton Depression Rating Scale suicide item). Whereas significant reduction of SI emerged when assessed via clinician rating in the MBCT and CBASP group, but not in the TAU group while controlling for changes in depression, there was no significant effect of treatment on SI when assessed via self-report.

LIMITATIONS

SI was measured with only two single items.

CONCLUSIONS

Because all effects were of small to medium size and were independent of effects from other depression symptoms, the present results warrant the application of such psychotherapeutical treatment strategies like MBCT and CBASP for SI in patients with chronic depression.

Suicidal ideation in youth with tic disorders

BACKGROUND

This study examined the incidence and clinical correlates of suicidal ideation (SI) in youth with tic disorders (TD). The independent contribution of tics, anxiety, depressive and externalizing symptoms on SI severity in youth with TD was assessed.

METHOD

Participants were 75 treatment-seeking youth with a TD (N=75) aged 6-18. Participants completed diagnostic assessments, clinician-ratings, self- and parent-report measures of emotional functioning and the presence and/or severity of suicidal ideation.

RESULTS

Based on youth-report, 61% of youth endorsed at least some symptoms of SI, and 8% endorsed symptoms that exceeded the clinically significant cut-off. Parents reported SI in 11% of cases, with generally poor agreement between parent- and youth-report. Suicidal ideation correlated with higher anxiety, depressive and externalizing symptoms, affective lability, and with poorer distress tolerance and overall functioning. Anxiety, depressive and externalizing symptoms showed an independent relationship with SI. Tic severity was not associated with SI. Rather, higher tic severity was associated with an increase in anxiety symptoms, which in turn, was associated with greater SI severity.

LIMITATIONS

Cross-sectional data limits causal conclusions. Diagnosis was based on unstructured assessments by expert clinicians, including consensus diagnosis, rather than structured clinical interviews.

CONCLUSIONS

Around 8-11% of youth with TD experienced SI. Tic severity did not have any direct influence on SI, however the presence of comorbid anxiety and depressive symptoms significantly increases this risk. Results suggest that it is psychiatric comorbidity, rather than tics themselves, that predispose youth with tic disorders to increased risk of suicidality.

Coping with suicidal urges among youth seen in a psychiatric emergency department

This study of youth seeking psychiatric emergency department (ED) services examined (1) youth self-efficacy to use suicide-specific coping strategies, (2) whether these self-efficacy beliefs varied by demographic and clinical characteristics, (3) and associations of these beliefs with suicide attempts and ED visits 3-5 months later. Participants were 286 psychiatric ED patients (59% Female), ages 13-25. Ratings of self-efficacy to engage in 10 suicide-specific coping behaviors were assessed at index visit. A total of 226 participants (79%) were assessed 3-5 months later. Youth endorsed low-to-moderate self-efficacy for different suicide-specific coping behaviors, with lowest ratings endorsed for limiting access to lethal means and accessing professional resources. More severe baseline psychopathology was associated with lower self-efficacy. Males endorsed higher self-efficacy for coping behaviors not requiring external support. Lower coping self-efficacy for some of the key strategies, and lower confidence that these strategies will be helpful, differentiated those with and without follow-up suicide attempts and ED visits. The generally low-to-moderate confidence in youths' ability to engage in coping behaviors to manage suicidal crises, and its association with follow-up suicidal crises, is concerning because many of these strategies are commonly included as part of discharge recommendations or safety planning. Implications of findings are discussed.

Reliability and Validity of a Brief Measure of Loneliness with Anglo-American and Mexican American Adolescents

This article focuses on the operating characteristics of an eight-item loneliness scale developed by the second author. Data from a sample of 2,600 Mexican American and Anglo-American middle school students indicate the scale, the RULS-8, has good reliability and validity. Cronbach's alpha was .87 for Mexican American and .90 for Anglo-American students. Principal components factor analysis yielded one factor accounting for 55.5% of the variance, with little variation across groups. Correlations with measures of depression, anxiety, suicidal ideation, self-esteem, social skills, and other measures were in the direction and on the order of magnitude predictedfrom other studies of loneliness, providing evidence for construct validity. Overall, the RULS-8 appears to provide an acceptable and parsimonious measure of adolescent loneliness suitable for use in mental health surveys.

Predictors of Suicide Attempts Among Gay, Lesbian, and Bisexual Youth

This research identified predictors of past suicide attempts in 194 lesbian, gay, and bisexual youth, 15 through 21 years of age, who attended social and recreational groups in urban community settings. In comparison to youth who made no suicide attempts, attempters reported that they had disclosed more completely their sexual orientation to others, had lost more friends because of their disclosures, and had experienced more victimization due to their sexual orientation. Suicide attempters had lower self-esteem and acknowledged more mental health problems. The loss offriends due to youth 's sexual orientation, and current suicidal ideation were among the strongest predictors of suicide attempts. Youth who reported early awareness of their sexual orientation, disclosure to family and friends, peer rejection, and victimization based on their sexual orientation may be at risk for mental health problems.

An Ecological Risk-Factor Examination of Suicide Ideation and Behavior of Adolescents

Using an ecological risk-factor approach, this study sought to identify risk factors related to suicidal behavior in a sample of 14,922 adolescents (11,027 European American adolescents and 3,895 African American adolescents) drawn from Michigan. Logistic regression analyses were used to determine significant predictors and to calculate a cumulative risk analysis. For both African American and European American males, risk factors related to frequent suicidal ideation and suicidal behavior were found at three levels of the social ecology: individual, family, and extrafamilial. Risk factors were also detected at all three levels of the ecology for both African American and European American females in terms of suicide attempts but not in terms of frequent suicidal thoughts. More similarities were found between the two ethnic groups and between males and females in terms of risk factors for suicidal ideation and attempted suicide. Results lend support to the use of an ecological risk-factor model for examining suicidal thoughts and attempts.

Hopelessness and Loneliness Among Suicide Attempters in School-Based Samples of Taiwanese, Philippine and Thai Adolescents

The aim of this study was to assess the level of suicide attempts in three school-based samples of Southeast Asian adolescents (Taipei, Taiwan; the Philippines; Chiang Mai, Thailand) and determine whether adolescent suicide attempters score higher on measures of hopelessness and loneliness relative to nonattempters. It was hypothesized that hopelessness and loneliness would be related to suicide attempts, and that hopelessness would continue to be associated with suicide attempts when controlling for loneliness. The prevalence of suicide attempts across the three samples of Asian youth were not consistent with Taiwanese girls and boys as the most likely to have ever attempted suicide. As expected, results showed that suicide attempters (in past 12 months and ever) scored higher on hopelessness and loneliness than nonattempters across all three samples and for both genders. However, the statistical control of loneliness demonstrably weakened the association between suicide attempt behaviour and hopelessness across the samples and for both genders, and resulted in nonsignificant ANCOVA tests for some of the sample-gender groups. These results attest to the need for more research investigating connections between youth suicide attempts, hopelessness and loneliness in adolescent populations. Loneliness should be included as a potential determinant of youth suicidal behaviour in future research.

Mattering and Suicide Ideation: Establishing and Elaborating a Relationship

Mattering is the belief that one makes a difference in the lives of others. We explore the effect of mattering on adolescent suicide ideation. The data source is the 2000 Youth At Risk Survey, composed of interviews with 2,004 youths, age 11–18 and screening interviews with their parents. Our analysis reveals that those who matter more are significantly less likely to consider suicide. In addition, we elaborate the relationship between mattering and suicide ideation by postulating a series of intervening variables (self-esteem and depression): mattering influences levels of self-esteem, which in turn influences depression, which ultimately leads to suicide ideation. Results demonstrate that mattering is mediated fully by these intervening variables, and that self-esteem is the primary source of the mediation. We discuss the implications of these results for adolescents' self-concepts.

Psychiatric outcomes after pediatric sports-related concussion

OBJECT

The objectives of this study were twofold: (1) to examine the prevalence of emotional symptoms among children and adolescents with a sports-related concussion (SRC) who were referred to a multidisciplinary pediatric concussion program and (2) to examine the prevalence, clinical features, risk factors, and management of postinjury psychiatric outcomes among those in this clinical population.

METHODS

The authors conducted a retrospective chart review of all patients with SRC referred to a multidisciplinary pediatric concussion program between September 2013 and October 2014. Clinical assessments carried out by a single neurosurgeon included clinical history, physical examination, and Post-Concussion Symptom Scale (PCSS) scoring. Postinjury psychiatric outcomes were defined as a subjective worsening of symptoms of a preinjury psychiatric disorder or new and isolated suicidal ideation or diagnosis of a novel psychiatric disorder (NPD). An NPD was defined as a newly diagnosed psychiatric disorder that occurred in a patient with or without a lifetime preinjury psychiatric disorder after a concussion. Clinical resources, therapeutic interventions, and clinical and return-to-play outcomes are summarized.

RESULTS

One hundred seventy-four patients (mean age 14.2 years, 61.5% male) were included in the study. At least 1 emotional symptom was reported in 49.4% of the patients, and the median emotional PCSS subscore was 4 (interquartile range 1-8) among those who reported at least 1 emotional symptom. Overall, 20 (11.5%) of the patients met the study criteria for a postinjury psychiatric outcome, including 14 patients with an NPD, 2 patients with isolated suicidal ideation, and 4 patients with worsening symptoms of a preinjury psychiatric disorder. Female sex, a higher initial PCSS score, a higher emotional PCSS subscore, presence of a preinjury psychiatric history, and presence of a family history of psychiatric illness were significantly associated with postinjury psychiatric outcomes. Interventions for patients with postinjury psychiatric outcomes included pharmacological therapy alone in 2 patients (10%), cognitive behavioral therapy alone in 4 (20%), multimodal therapy in 9 (45%), and no treatment in 5 (25%). Overall, 5 (25%) of the patients with postinjury psychiatric disorders were medically cleared to return to full sports participation, whereas 5 (25%) were lost to follow-up and 9 (45%) remained in treatment by the multidisciplinary concussion program at the end of the study period. One patient who was asymptomatic at the time of initial consultation committed suicide.

CONCLUSIONS

Emotional symptoms were commonly reported among pediatric patients with SRC referred to a multidisciplinary pediatric concussion program. In some cases, these symptoms contributed to the development of an NPD, isolated suicidal ideation, and worsening symptoms of a preexisting psychiatric disorder. Future research is needed to clarify the prevalence, pathophysiology, risk factors, and evidence-based management of postinjury psychiatric outcomes after pediatric SRC. Successful management of these patients requires prompt recognition and multidisciplinary care by experts with clinical training and experience in concussion and psychiatry.

Suicidal ideation and bullying among Australian secondary school students

Bully-victim problems at school may have negative effects on students' mental health. Adolescents (N = 845) attending schools in South Australia anonymously answered questionnaires that included a measure of suicidal ideation. Student involvement in bully-victim problems at school and the emotional reaction to being viaimised by peers were also examined. Self-report but not peer nomination indicated that high levels of peer victimisation and relatively ineffective coping responses were independently and significantly associated with suicidal ideation. Implications for school policies and practices to address the issue of youth suicide are discussed.

Pathways From Bullying Perpetration, Victimization, and Bully Victimization to Suicidality Among School-Aged Youth: A Review of the Potential Mediators and a Call for Further Investigation

In the wake of several highly publicized adolescent suicides attributed to bullying victimization, national attention has been brought to bear on the profound public health problem of bullying. This article reviews the extant literature on the associations between bullying perpetration, victimization, and thoughts of or attempts at suicide and proposes five potential mediators, namely depression, anxiety, low self-esteem, loneliness, and hopelessness, that may explain this relationship. Numerous studies have found empirical support for the interrelations between internalizing behaviors and both bullying perpetration and victimization and suicide. We find that further longitudinal research needs to be conducted to more conclusively determine the role and causal ordering these various psychosocial factors may play in bullying perpetration, victimization, and suicide. Although the research literature implies causal directions among all these potential mediators, untangling the unique influence of bullying perpetration, victimization, and bully victimization on suicide and its mechanisms of action has major research and practice implications.

A Finite Element Study of the Dynamic Response of Brain Based on Two Parasagittal Slice Models

The objective of this study is to investigate the influence of gyri and sulci on the response of human head under transient loading. To this end, two detailed parasagittal slice models with and without gyri and sulci have been developed. The models comprised not only cerebrum and skull but also cerebellum, brain stem, CSF, and corpus callosum. In addition, white and gray matters were separated. The material properties were adopted from the literature and assigned to different parts of the models. Nahum's and Trosseille's experiments reported in relevant literature were simulated and the simulation results were compared with the test data. The results show that there is no evident difference in terms of intracranial pressure between the models with and without gyri and sulci under simulated conditions. The equivalent stress below gyri and sulci in the model with gyri and sulci is slightly higher than that in the counterpart model without gyri and sulci. The maximum principle strain in brain tissue is lower in the model with gyri and sulci. The stress and strain distributions are changed due to the existence of gyri and sulci. These findings highlight the necessity to include gyri and sulci in the finite element head modeling.

Perceived family and peer invalidation as predictors of adolescent suicidal behaviors and self-mutilation

OBJECTIVE

The present study investigates the longitudinal relationship between perceived family and peer invalidation and adolescent suicidal events (SE) and self-mutilation (SM) in a 6 month follow-up (f/u) study of adolescents admitted to an inpatient psychiatric unit for suicide risk.

METHODS

Adolescents (n=119) and their parent(s) were administered interviews and self-report assessments at baseline and at a 6 month f/u, with 99 (83%) completing both assessments. The Adolescent Longitudinal Interval Follow-Up Evaluation (A-LIFE) was modified to provide weekly ratings (baseline and each week of f/u) for perceived family and peer invalidation. Regression analyses examined whether: 1) Prospectively rated perceived family and peer invalidation at baseline predicted SE and SM during f/u; and 2) chronicity of perceived invalidation operationalized as proportion of weeks at moderate to high invalidation during f/u was associated with SE and SM during f/u.

RESULTS

Multiple regression analyses, controlling for previously identified covariates, revealed that perceived family invalidation predicted SE over f/u for boys only and perceived peer invalidation predicted SM over f/u in the overall sample. This was the case for both baseline and f/u ratings of perceived invalidation.

CONCLUSIONS

Our results demonstrate the adverse impact of perceived family and peer invalidation. Specifically, boys who experienced high perceived family invalidation were more likely to have an SE over f/u. Both boys and girls who experienced high perceived peer invalidation were more likely to engage in SM over f/u.

Suicide attempts and stressful life events among female victims of intimate partner violence living in poverty in Nicaragua

This article describes a study of 136 female intimate partner violence victims living in poverty in Nicaragua. The paper aimed to analyze the relationship between experiencing stressful life events (SLE) and perceived social support with suicide attempts, and to evaluate the differences in the SLE experienced by female suicide attempters versus non-attempters. The results showed the existence of a high level of SLE among the interviewees, and that women who have attempted suicide have experienced substantially more of these events. Experiences of violence and less social support were especially related to suicide attempts among the interviewees.

Adolescent inpatient girls׳ report of dependent life events predicts prospective suicide risk

Adolescents with a history of suicidal behavior are especially vulnerable for future suicide attempts, particularly following discharge from an inpatient psychiatric admission. This study is the first to test whether adolescents׳ tendency to generate stress, or report more dependent events to which they contributed, was predictive of prospective suicide events. Ninety adolescent psychiatric inpatients who were admitted for recent suicide risk, completed diagnostic interviews, assessments of history of suicidal behavior, and a self-report questionnaire of major life events at baseline. Participants were followed over the subsequent 6 months after discharge to assess stability vs. onset of suicide events. Cox proportional hazard regressions were used to predict adolescents׳ time to suicide events. Results supported hypothesis, such that only recent greater dependent events, not independent or overall events, predicted risk for prospective suicide events. This effect was specific to adolescent girls. Importantly, dependent events maintained statistical significance as a predictor of future suicide events after co-varying for the effects of several established risk factors and psychopathology. Results suggest that the tendency to generate dependent events may contribute unique additional prediction for adolescent girls׳ prospective suicide risk, and highlight the need for future work in this area.

Risk factors for suicide attempts in the total population of Faroese eighth graders

Objectives:

Suicide is still one of the leading causes of youth mortality, and amongst others previous suicide attempts have been found to be one of the strongest risk factors for suicide. The objective of this study is to examine risk factors of suicide attempts in a total population of Faroese adolescents. It is expected that anxious attachment, high scores on negative affectivity and low scores on past and present social support were correlated to an increased risk of life-time suicide attempts in both female and male adolescents.

Method:

Analyses were conducted based on data from The Faroese Adolescent Trauma Study, a self-report questionnaire survey including a total population of Faroese eighth graders (N = 687; 85 % response rate, mean age 14.2 years, SD = 2.1). The questionnaire included The Revised Adult Attachment Scale (RAAS), The Trauma Symptom Checklist (TSC), and The Crisis Support Scale (CSS).

Results:

In the total population 9.9 % (N = 68) of the participants reported life-time suicide attempt; of those 28 % were boys and 72 % were girls. In line with the expectations, the initial comparison showed that adolescents reporting life-time suicide attempt had significantly higher scores on attachment anxiety and negative affectivity, and had significantly lower scores on attachment closeness, and both past and present social support. Further analyses stratified on gender, however, revealed unexpected results, as a high score on negative affectivity only was a significant risk factor for life-time suicide attempt among the girls, and high score on attachment closeness only was a significant protective factor of life-time suicide attempt among the boys.

Conclusions:

This study provides important data about the role of attachment, negative affectivity, and social support in suicide attempts in a total population of Faroese adolescents. Moreover the results show the necessity of taking gender into account in research of risk and protective factors of suicide attempts, and when establishing arrangements to prevent and treat suicide attempts in adolescents.

Life-time and current suicide-ideation in Australian secondary school students: Socio-demographic, health and psychological predictors

BACKGROUND

This study involved a multi-level analysis of factors related to self-reported suicidality (both current and life-time) in adolescents

METHODS

A sample of 2552 students aged 14-16 years answered questions relating to demographics, social and familial functioning, psychological well-being and suicidality.

RESULTS

Suicidality, defined as being at least some element of reported suicide ideation, Behaviourally, suicidality was also more likely if students smoked, drank alcohol without adult supervision or if they took illicit drugs was more likely in girls, and in those with poorer social, family and psychological functioning. Behaviourally, suicidality was also more likely if students smoked, drank alcohol or took illicit drugs. Multi-level modelling showed that negative affect, substance use and the presence of romantic relationships were most strongly associated with suicidality. Both current and life-time measures of suicidality showed similar results. Both models suggested that the presence of substance use in teenagers is a potentially useful indicator of elevated suicide risk and that many of the social problems commonly associated with suicidality are likely to be mediated by negative affective states.

LIMITATIONS

The study had several limitations. First, it was cross-sectional so it was not possible to examine how variables measured at one time predicted subsequent suicidality. Second, the present analyses were based on a single measure of suicidality that did not differentiate between ideation and attempts. Thus, the analyses did not indicate the severity of the suicidality: whether it involved ideation or actual attempts.

CONCLUSIONS

Adolescent girls and adolescents with poor social and family functioning and those who engage in substance use are at risk of suicidal ideation (a known precursor of suicide attempts). School counsellors and teachers need to be aware of the risks.

Suicidal behaviors in depressed adolescents: role of perceived relationships in the family

CONTEXT

Suicide is the second leading cause of death in adolescents and young adults in Europe. Reducing suicides is therefore a key public health target. Previous studies have shown associations between suicidal behaviors, depression and family factors.

OBJECTIVE

To assess the role of family factors in depression and suicidality in a large community-based sample of adolescents and to explore specific contributions (e.g. mother vs. father; conflict vs. no conflict; separation vs. no separation) taking into account other risk factors.

METHODS

A cross-sectional sample of adolescents aged 17 years was recruited in 2008. 36,757 French adolescents (18,593 girls and 18,164 boys) completed a questionnaire including socio-demographic characteristics, drug use, family variables, suicidal ideations and attempts. Current depression was assessed with the Adolescent Depression Rating Scale (ADRS). Adolescents were divided into 4 groups according to suicide risk severity (grade 1 = depressed without suicidal ideation and without suicide attempts, grade 2 = depressed with suicidal ideations and grade 3 = depressed with suicide attempts; grade 0 = control group). Multivariate regressions were applied to assess the Odds Ratio of potential risk factors comparing grade 1, 2 or 3 risk with grade 0.

RESULTS

7.5% of adolescents (10.4% among girls vs. 4.5% among boys) had ADRS scores compatible with depression; 16.2% reported suicidal ideations in the past 12 months and 8.2% reported lifetime suicide attempts. Repeating a year in school was significantly associated to severity grade of suicide risk (1 and 3), as well as all substance use, tobacco use (severity grades 2 and 3) and marijuana use (severity grade 3), for girls and boys. After adjustment, negative relationships with either or both parents, and parents living together but with a negative relationship were significantly associated with suicide risk and/or depression in both genders (all risk grades), and Odds Ratios increased according to risk severity grade.

CONCLUSION

Family discord and negative relationship with parents were associated with an increased suicide risk in depressed adolescents. So it appears essential to take intrafamilial relationships into account in depressed adolescents to prevent suicidal behaviours.

Key Characteristics of Major Depressive Disorder Occurring in Childhood, Adolescence, Emerging Adulthood, Adulthood

This paper summarizes characteristics of major depressive disorder (MDD) in the Oregon Adolescent Depression Project, using data from 816 participants (56% female; 89% White). Contrasting four developmental periods (Childhood [5-12.9], Adolescence [13-17.9], Emerging Adulthood [18-23.9], Adulthood [24-30]), we examine MDD incidence/recurrence, gender, comorbidity, duration, and suicide attempts across periods. MDD first incidence was lower in Childhood compared to subsequent periods, and higher in Emerging Adulthood than Adulthood. Cumulative incidence was 51%. Recurrence was lower during Childhood than remaining periods, which were comparable. Female gender predicted first incident MDD in all four periods but was unassociated with recurrence. Comorbidity rates were comparable across periods. MDD duration was greater in Childhood than remaining periods. Suicide attempt rates were significantly higher during Adolescence than either Emerging Adulthood or Adulthood. Depression research should focus on MDD during Emerging Adulthood, adolescent suicidal behavior, the continuing role of gender into adulthood, and the ubiquity of MDD.

Depression, aggression, and suicidal ideation in first graders: a school-based cross-sectional study

OBJECTIVE

This study explored the clinical characteristics and risk factors of suicidal ideation in a sample of first graders from South Korea. Children's depression and aggression and maternal depression were examined as possible risk factors.

METHODS

This study is a school-based, cross-sectional study of 5 elementary schools in Gunpo City, South Korea. Participants were 707 first graders (mean age, 6.54 years) and their mothers. We assessed children's depressive and aggressive symptoms using the Behavior Assessment System for Children-2 (BASC-2) and maternal depression using the Beck Depression Inventory (BDI). Two items from BASC-2 and 1 item from BDI identified children's and maternal suicidal ideation.

RESULTS

Twenty-seven (3.8%) children evidenced suicidal ideation. Children with suicidal ideation had higher mean scores of depression domain (10.11 ± 5.34 vs 4.57 ± 3.44, P < .0001) and aggression domain (7.78 ± 3.84 vs 3.80 ± 2.85, P < .0001) on BASC-2 and maternal depression (9.78 ± 6.45 vs 7.28 ± 5.38, P = .02) on BDI. In regression analysis, children's depression (odds ratio [OR], 1.19; 95% confidence interval [CI], 1.07-1.32; P = .001) and aggression (OR, 1.24; 95% CI, 1.08-1.41; P = .002) contributed significantly to children's suicidal ideation, whereas maternal depression was not significantly related to children's suicidal ideation (OR, 0.99; 95% CI, 0.92-1.06; P = .75).

CONCLUSIONS

This study demonstrated that even first graders had a considerable prevalence of suicidal ideation and that depression and aggression were associated with suicidal ideation in young children.

Differences in risk factors for suicide attempts among 9th and 11th grade youth: a longitudinal perspective

The purpose of the study is to assess the relationship between timing of adolescent development and risk factors for suicide. Nationally representative data from the Add Health survey were used. The relationship of sociodemographic characteristics, known risk factors, and physical developmental timing and cognitive developmental style to suicide attempt was assessed. Depression was a risk factor for suicide attempts in both 9th and 11th grade. Other risk factors differed. Use of illegal drugs, homosexual orientation, using public assistance, and physical development were the important risk factors for ninth graders. For 11th graders, sexual abuse, being in counseling, and being of "other" race or ethnicity (mainly Asian or Native American) were risk factors. The cognitive development variable of using a systematic problem-solving method was protective for 11th graders. Recognizing that risk factors for adolescent suicide attempts change over time and with developmental timing of puberty is an important factor for suicide prevention strategies.

Suicide attempters and repeaters: depression and coping: a prospective study of early adolescents followed up as young adults

Relationships between depression and coping among nonattempters, attempters, and repeaters of suicidal acts were examined across adolescence. A representative sample of students (T1: n = 2464; mean age, 13.7 years; 50.8% female; 88.3% participation) was reassessed with the same questionnaire after 1 year (T2). High scorers on the Mood and Feelings Questionnaire were gender- and age-matched randomly with low and middle scorers. This subset was assessed using diagnostic interviews at T2 (n = 345, 94% participation) and 5 years later using the same interview and questionnaire (T3, n = 252; mean age, 20.0 years; 73% participation). The Coping Inventory for Stressful Situations measured coping as three stable traits. Coping changed partly with age, depression, and attempt status. Differences in depression emerged before coping differences and remained stable. Consistently, repeaters reported higher depression and lesser task-oriented coping. Antecedent depression predicted decreased task-oriented coping and increased emotional coping at age 20 years.

Etiological features of borderline personality related characteristics in a birth cohort of 12-year-old children

It has been reported that borderline personality related characteristics can be observed in children, and that these characteristics are associated with increased risk for the development of borderline personality disorder. It is not clear whether borderline personality related characteristics in children share etiological features with adult borderline personality disorder. We investigated the etiology of borderline personality related characteristics in a longitudinal cohort study of 1,116 pairs of same-sex twins followed from birth through age 12 years. Borderline personality related characteristics measured at age 12 years were highly heritable, were more common in children who had exhibited poor cognitive function, impulsivity, and more behavioral and emotional problems at age 5 years, and co-occurred with symptoms of conduct disorder, depression, anxiety, and psychosis. Exposure to harsh treatment in the family environment through age 10 years predicted borderline personality related characteristics at age 12 years. This association showed evidence of environmental mediation and was stronger among children with a family history of psychiatric illness, consistent with diathesis-stress models of borderline etiology. Results indicate that borderline personality related characteristics in children share etiological features with borderline personality disorder in adults and suggest that inherited and environmental risk factors make independent and interactive contributions to borderline etiology.

Evaluating the predictive validity of suicidal intent and medical lethality in youth

OBJECTIVES

To examine whether suicidal intent and medical lethality of past suicide attempts are predictive of future attempts, the association between intent and lethality, and the consistency of these characteristics across repeated attempts among youth.

METHOD

Suicide attempts in a 15-year prospective study of 180 formerly psychiatrically hospitalized adolescents (M(age at hospitalization) = 14.83; 51% female; 80% Caucasian) were characterized with the Subjective Intent Rating Scale and Lethality of Attempt Rating Scale. Anderson-Gill recurrent events survival models and generalized estimating equations were used to assess predictive validity. Generalized linear models were used to examine stability of characteristics across attempts.

RESULTS

Neither intent nor lethality from the most recent attempt predicted future attempts. The highest level of intent and most severe lethality of attempts during the follow-up predicted subsequent attempts, but the degree to which highest intent and most severe lethality contributed to prediction after considering methods of suicide attempts, past number of attempts, or psychiatric diagnoses was mixed. Across successive attempts, there was little consistency in reported characteristics. Intent and lethality were related to each other only for attempts occurring in early adulthood.

CONCLUSIONS

Highest intent and lethality were better predictors of future attempts than intent and lethality of the most recent attempt. However, these characteristics should be considered as predictors only within the context of other factors. For youth, clinicians should not infer true intent from the lethality of attempts, nor assume that characteristics of future suicide attempts will be similar to those of previous attempts.

Young people's risk of suicide attempts after contact with a psychiatric department - a nested case-control design using Danish register data

BACKGROUND

There seems to be an increased risk of children and adolescents committing or attempting suicide after contact with a psychiatric department. Children and adolescents living in families with low socio-economic status (SES) might have an especially increased suicide attempt risk.

METHODS

A complete extraction of Danish register data for every individual born in the period 1983-1989 was made. Of these 403,431 individuals, 3,465 had attempted suicide. In order to control for confounder effects from gender, age and calendar-time, a nested case-control study was designed. A total population of 72,765 individuals was used to analyze the risk of suicide attempts after contact with a psychiatric department. The case-control data were analyzed using conditional logistic regression.

RESULTS

This study shows that a child/adolescent's risk of suicide attempt peaks immediately after discharge from last contact with a psychiatric department. The risk of suicide attempt is highest for children and adolescents suffering from personality disorders, depression and substance use disorders. Children and adolescents with previous contact with a psychiatric department and parental income in the lowest third have a significantly higher risk of suicide attempt. Suicide attempters were more likely to have been given several different diagnoses and several different psychopharmacological drugs prior to their attempted suicide.

CONCLUSIONS

The findings in this study highlight the need for psychopathology assessment in every case of attempted suicide. This study also shows that well-known risk factors such as contact with a psychiatric department do not affect all individuals in the same way. Individuals from families with low SES had the highest risk. This suggests that the presence of factors influencing both vulnerability and resiliency, e.g., family level of SES, needs to be included in the assessment.

Predicting Suicidal Risk in a Cohort of Depressed Children and Adolescents

Background: In children and adolescents with a depressive disorder, predicting who will also go on to exhibit suicide-related behaviors (SRBs), including suicide attempt or self-harm, is a key challenge facing clinicians. Aims: To investigate the relative contributions of depressive disorder severity, hopelessness, family dysfunction, and perceived social support to the risk of suicide-related behaviors. Methods: This was a cross-sectional study of a group of 10–16-year-olds with major depressive disorders and dysthymic disorder. Results: Child-rated depressive disorder symptom severity emerged as the greatest predictor of risk. Hopelessness and family dysfunction were also significant predictors of SRBs. In combination these variables were strong predictors, accounting for 66% of the variance. This is a cross-sectional study design, rather than longitudinal, therefore risk prediction over time was not possible. Conclusions: Understanding the child and adolescents depressive disorder symptom severity from their perspective, their level of hopelessness, as well as their family context is critical in understanding the risk of SRBs. These findings may help to provide direction for targeted interventions to address these clinical risk factors.

Early onset major depressive disorder

The present paper provides an overview of the clinical diagnosis and presentation, epidemiology, coexisting problems, and treatment issues of child and adolescent depressive disorders, with a focus on major depressive disorder (MDD). Depression is a common and potentially debilitating disorder for youth; has significant comorbid, behavioural and systemic sequelae; and is associated with a significant suicidal risk. Although rigorous study of psychosocial and pharmacological treatment modalities is in its infancy, current treatment is also informed by judicious and patient-specific clinical judgment. In view of the duration of MDD, remission and recurrence rates, morbidity, and potential chronicity of impaired psychosocial functioning, both active treatment and research involving MDD are indicated.

Life events as precipitants of suicide attempts among first-time suicide attempters, repeaters, and non-attempters

The aims of this study were to investigate risk factors for suicide attempts and propose a model explaining the associations among life events and suicide status. We assessed 263 subjects admitted following a suicide attempt to the Division of Psychiatry of the Department of Neurosciences of the University of Parma and compared them with 263 non-attempter clinical control subjects. Attempters reported significantly more adverse life events both in the last 6 months, and between the ages of 0-15 years than non-attempters. A multinomial logistic regression analysis with stepwise forward entry indicated that the best model to explain suicide status was one which included life events in the last 6 months, life events during age 0-15 years, and their interaction. First-time attempter status (vs. non-attempters) was more likely to be linked to life events in the last 6 months, the interaction between life events in the last 6 months and life events during age 0-15 years, and low social support. Those attempters with one or more prior attempts (repeat attempters) were more likely than non-attempters to be linked to the interaction between life events in the last 6 months and life events during age 0-15 years, and to higher rates of psychopharmacological treatment before the index admission. Guided by these findings, monitoring the impact of early-life and recent events in vulnerable individuals should be part of risk assessment and treatment.
