Prevalence and Correlates of Youth Suicidal Ideation and Attempts: Evidence from the 2014 Ontario Child Health Study

Examining Predictors of Psychological Distress Among Youth Engaging with Jigsaw for a Brief Intervention

Risk factors for psychological distress among help-seeking youth are poorly understood. Addressing this gap is important for informing mental health service provision. This study aimed to identify risk factors among youth attending Jigsaw, a youth mental health service in Ireland. Routine data were collected from N = 9,673 youth who engaged with Jigsaw (Mean age = 16.9 years, SD = 3.14), including presenting issues, levels of psychological distress, age, and gender. Confirmatory Factor Analysis identified thirteen factors of clustering issues. Several factors, including Self-criticism and Negative Thoughts, were strongly associated with items clustering as psychological distress, however these factors were poorly predictive of distress as measured by the CORE (YP-CORE: R2 = 14.7%, CORE-10: R2 = 6.9%). The findings provide insight into associations between young people's identified presenting issues and self-identified distress. Implications include applying appropriate therapeutic modalities to focus on risk factors and informing routine outcome measurement in integrated youth mental health services.

Suicide ideation and psychotropic recreational drug use by adolescents: a systematic review and meta-analysis

BACKGROUND

Adolescence is characterized by complex and dynamic changes, often involving experimentation, including the use of psychotropic substances. Although it is well-established that recreational psychotropic drugs are associated with suicide ideation in adults, evidence of this association in adolescents remains limited.

OBJECTIVE

To investigate the relationship between suicide ideation and psychotropic recreational drug use among adolescents.

DESIGN AND SETTING

Systematic review with meta-analysis developed at Universidade Federal de Uberlândia (UFU) and Universidade Estadual de Campinas (UNICAMP), Brazil.

METHODS

A search across eight electronic databases for observational studies, without language or publication year restrictions, was conducted. The Joanna Briggs Institute tool was used to assess the risk of bias. Random-effects meta-analyses and odds ratios were used to measure the effects.

RESULTS

The search yielded 19,732 studies, of which 78 were included in the qualitative synthesis and 32 in the meta-analysis. The findings indicated that suicidal ideation was 1.96 times more likely (95% confidence interval, CI = 1.47; 2.61) for adolescents who used some drug recurrently and 3.32 times more likely (95%CI = 1.86; 5.93) among those who abused drugs. Additionally, adolescents who used cannabis were 1.57 times more likely (95%CI = 1.34; 1.84) to experience suicide ideation compared with non-users, while cocaine users had 2.57 times higher odds (95%CI = 1.47; 4.50).

CONCLUSIONS

Psychotropic recreational drug use is associated with suicidal ideation among adolescents regardless of current or previous use, abuse, or type of substance used.

Identifying patterns of substance use and mental health concerns among adolescents in an outpatient mental health program using latent profile analysis

Though mental health and substance use concerns often co-occur, few studies have characterized patterns of co-occurrence among adolescents in clinical settings. The current investigation identifies and characterizes these patterns among adolescents presenting to an outpatient mental health service in Ontario, Canada. Data come from cross-sectional standardized patient intake assessments from 916 adolescents attending an outpatient mental health program (January 2019-March 2021). Latent profile analysis identified patterns of substance use (alcohol, cannabis, (e-) cigarettes) and emotional and behavioral disorder symptoms. Sociodemographic and clinical correlates of these patterns were examined using multinomial regression. Three profiles were identified including: 1) low substance use and lower frequency and/or severity (relative to other patients in the sample) emotional and behavioral disorder symptoms (26.2%), 2) low substance use with higher emotional and behavioral disorder symptoms (48.2%), and 3) high in both (25.6%). Profiles differed in sociodemographic and clinical indicators related to age, gender, trauma, harm to self, harm to others, and service use. Experiences of trauma, suicide attempts, and thoughts of hurting others increased the odds of adolescents being in the profile high in both substance use and symptoms compared to other profiles. These findings further document the high rates of substance use in adolescents in mental health treatment and the profiles generally map onto three out of four quadrants in the adapted four-quadrant model of concurrent disorders, indicating the importance of assessing and addressing substance use in these settings.

Examining the integrated model of the interpersonal-psychological theory of suicide and intersectionality theory among Black male adolescents

INTRODUCTION

Guided by Opara et al.'s (2022), Integrated Model of the Interpersonal Psychological Theory of Suicide and Intersectionality Theory, the current study examined contextual stressors experienced disparately by Black youth (racial discrimination, poverty, and community violence) as moderators of the association between individual motivating factors for suicidal thoughts and behaviors (perceived burdensomeness, thwarted belongingness, and hopelessness) and active suicidal ideation.

METHOD

Participants were 457 Black adolescent boys (mean age = 15.31, SD = 1.26) who completed self-report surveys.

RESULTS

As predicted, the association between perceived burdensomeness and active suicidal ideation was significantly moderated by economic stress. In addition, the association between peer belongingness and suicidal ideation was significantly moderated by racial discrimination, but there were no moderating effects for school belongingness. Finally, the association between hopelessness and suicidal ideation was significantly moderated by both racial discrimination and witnessing community violence.

CONCLUSION

These findings highlight the need for research, interventions, and policy work devoted to using integrated approaches of individual and socioeconomically relevant patterns of suicidal thoughts and behaviors to support Black youth exposed to various forms of structural oppression.

Risk Factors of Suicide Attempt among Adolescents with Suicide Ideation in Low- and Middle-Income Countries across the Globe

Suicide is a serious public health problem for adolescents. Based on the framework of ideation-to-action, it is important to examine the factors associated with the translation from suicide ideation to suicide attempt. The present study aimed to investigate the risk factors of suicide attempts among adolescents with suicide ideation in low-income and middle-income countries (LMICs). We analyzed data of students aged 12-18 years who participated in the 2009-2013 Global School-based Health Surveys (GSHS) in 39 LMICs. The Chi-square test was used to compare the prevalence of suicide attempts among participants with suicide ideation, the multilevel logistic regression model was used to identify significant factors associated with suicide attempts among suicide ideators. Among 22,655 adolescents with suicide ideation, 55.1% of them reported having made a suicide attempt in the past year. Loneliness, anxiety, alcohol use, and drug use were risk factors for suicide attempts among suicide ideators. Strategies should be implemented to reduce the likelihood of adolescents acting on their suicidal thoughts, such as community psychological crisis line, school-based mental health and skills training programs, and family support for adolescents with psychological problems.

Suicide attempt among Malaysian school-going adolescents: relationship with bullying

BACKGROUND

According to World Health Organization (WHO), the fourth leading cause of death among adolescents aged 15 -19 years is suicide. The National Health and Morbidity Survey (NHMS) 2017 reported that suicidal attempts among school adolescents increased from 6.8%-6.9% as compared to NHMS 2012. Suicide attempts can cause significant negative impacts on health, social and economic status. Bullying is one of the factors for adolescent suicide attempts, and its relationship to suicidality in adolescents has been shown in numerous research.

OBJECTIVES

This study examined the relationship between suicide attempts and bullying among school adolescents in Malaysia.

METHODS

Data from the Malaysia NHMS 2017, a nationwide study that adopted a two-stage cluster sampling design, were analysed. The survey used a self-administered questionnaire in bilingual language adapted from GSHS developed by WHO. Participants were secondary school students aged 13 -17 in all states. Descriptive and multiple logistic regression analyses were performed using IBM SPSS version 28.

RESULTS

A total of 27,497 school adolescents participated in the study. Results showed that 6.9% of school adolescents had attempted suicide. There was 16.2% of adolescents being bullied. Multiple logistic regression revealed that students who were bullied were more likely to have suicide attempts (aOR 4.827, 95% CI: 4.143, 5.624) P < 0.001.

DISCUSSION/CONCLUSION

This study revealed that bullying is associated with suicide attempts among school adolescents in Malaysia. The respective authority should consider and plan effective measures to curb bullying among school adolescents.

Profiles of Suicidal Ideation Among Black Male Adolescents: Examination of Individual and Socioecological Predictors

OBJECTIVE

The current study utilized latent profile analysis to identify distinct profiles of suicidal ideation among Black male adolescents and compared profiles on socioecological determinants of suicide and psychological symptoms.

METHOD

A sample of 457 Black male adolescents (mean age = 15.31, SD = 1.26) completed self-report measures of suicidal ideation, racial discrimination, community violence exposure, anxiety symptoms, depressive symptoms, and posttraumatic stress symptoms.

RESULTS

Results of the latent profile analysis revealed a three-profile model: a low ideation profile, with low levels of all forms of suicidal ideation; a general death ideation profile with elevated general thoughts of death and dying; and a high, concealed ideation profile with high levels on all suicidal ideation items, except communicating the ideation to others. ANOVAs revealed that levels of psychological symptoms were significantly different for each profile, with the high, concealed ideation profile showing the highest levels. The low ideation profile had significantly lower scores than the two other profiles on community violence exposure, but the other two profiles did not differ significantly from one another. Further, the general death ideation profile had significantly higher scores on racial discrimination than the other two profiles, but the other two profiles did not differ significantly from one another.

CONCLUSIONS

The current study supports recent socio-cultural theories of suicidal ideation and behavior in Black youth and highlights the need for increased access to care and services for Black boys who are exposed to socioecological factors that heighten suicidal ideation.

Typologies of child maltreatment and peer victimization and the associations with adolescent substance use: A latent class analysis

BACKGROUND

Child maltreatment and peer victimization are pervasive public health problems associated with adolescent substance use. Although child maltreatment has been identified as a risk factor for peer victimization, few studies have investigated their co-occurrence (i.e., polyvictimization). The study objectives were to: examine sex differences in the prevalence of child maltreatment, peer victimization, and substance use; identify polyvictimization patterns; and examine the associations between the identified typologies and adolescent substance use.

METHODS

Data were self-reported from a sample of adolescents aged 14 to 17 years (n = 2910) who participated in the provincially-representative 2014 Ontario Child Health Study. Latent class analysis with distal outcomes was conducted to identify typologies of six types of child maltreatment and five types of peer victimization and examine the associations between the polyvictimization typologies and use of cigarettes/cigars, alcohol, cannabis, and prescription drugs.

RESULTS

Four typologies were identified: Low victimization (76.6 %), Violent home environment (16.0 %), High verbal/social peer victimization (5.3 %), and High polyvictimization (2.1 %). The Violent home environment and High verbal/social peer victimization typologies were associated with increased odds of adolescent substance use (adjusted odds ratio range: 2.06-3.61). The High polyvictimization typology showed increased, but non-significant, odds of substance use.

CONCLUSIONS

Adolescent-serving health and social services professionals should be aware of polyvictimization patterns and the impact on substance use. For some adolescents, polyvictimization may include exposure to multiple child maltreatment and peer victimization types. Upstream strategies to prevent child maltreatment and peer victimization are needed, which may also contribute to reductions in adolescent substance use.

The Relationship Between Chronic Pain, Depression, Psychosocial Factors, and Suicidality in Adolescents

BACKGROUND

Chronic pain in youth is often associated with social conflict, depression, and suicidality. The interpersonal theory of suicide posits that there are psychosocial factors, such as peer victimization and lack of fear of pain, that may also influence suicidality.

OBJECTIVES

The objective of this study was to determine whether depressive symptoms, peer victimization, and lack of fear of pain predict suicidality in adolescents with chronic pain. It was hypothesized that higher levels of depressive symptoms and peer victimization, and lower levels of fear of pain, would predict a higher lifetime prevalence of suicidality.

METHODS

Participants consisted of 184 youth with primary chronic pain conditions (10 to 18 y, M = 14.27 y). Measures included diagnostic clinical interviews assessing suicidality and self-report questionnaires assessing depressive symptoms, peer victimization, and fear of pain.

RESULTS

Forty-two (22.8%) participants reported suicidality. Regression analyses demonstrated that the occurrence of suicidality was associated with higher rates of depressive symptoms (β = 1.03, P = 0.020, 95% CI: 1.01, 1.06) and peer victimization (β = 2.23, P < 0.05, 95% CI: 1.07, 4.63), though there was no association between lower fear of pain and suicidality.

DISCUSSION

These results suggest that depressive symptoms and peer victimization are significant predictors of suicidality in adolescents with chronic pain; however, lower fear of pain was not shown to be a significant predictor. Given these findings, depression and peer victimization should be further explored and considered in the design and implementation of prevention and early intervention strategies that target chronic pain and suicidality in youth.

Pathways of association between disordered eating in adolescence and mental health outcomes in young adulthood during the COVID-19 pandemic

OBJECTIVES

The COVID-19 pandemic has been associated with increased mental health problems. We investigated (1) associations between disordered eating in adolescence and mental health problems after one year of the pandemic and (2) the mechanisms explaining associations.

METHOD

We analyzed data from a population-based birth cohort in Quebec, Canada (557 males and 759 females). High and low levels of disordered eating symptom trajectories were previously estimated (age 12, 15, 17, and 20 years). Anxiety, depression, non-suicidal self-injury, and suicidal ideation were assessed at 23 years (March-June 2021). Putative mediators included loneliness and social media use (age 22 years, July-August 2020). Analyses controlled for mental health and socio-economic status at age 10-12 years and were conducted for males and females separately.

RESULTS

Females in the high-level disordered eating symptom trajectory were at increased risk for non-suicidal self-injury (OR 1.60; 95% CI 1.02-2.52) and suicidal ideation (2.16; 1.31-3.57), whereas males were at increased risk for severe anxiety (2.49; CI 1.11-5.58). Males and females in the high-level trajectory were more likely to report severe depression (2.26; 1.14-5.92 and 2.15, 1.36-3.38 respectively). Among females, associations were partially explained (17-35%) by loneliness during the first 4 months of the pandemic.

CONCLUSION

Young adults who experienced disordered eating as adolescents were at increased risk of mental health problems during the pandemic. Loneliness partially mediated the effect, suggesting that pandemic mitigation resulting in increased social isolation may have exacerbated mental health problems among women with a history of disordered eating.

The cross-sectional, longitudinal, and transitional associations between perceived support and suicidal ideation and behavior in late adolescence and emerging adulthood: Adjacent-category logit models

INTRODUCTION

Suicidal ideation (SI) and attempts (SA) are prevalent in late adolescence and emerging adulthood. Prior research has identified perceived support as a correlate of SI and SA. Less is known, though, about the role of perceived support in differentiating among suicidal outcomes and between the incremental escalation of suicidal outcomes from SI to SA to serious suicide attempts (SSA).

METHOD

Using ordinal regression, we used Wave 1 and 2 data from the National Longitudinal Study of Adolescent to Adult Health (N = 4500; 53% female; M_age  = 16.6; 12% Hispanic) to examine cross-sectional, longitudinal, and transitional models of perceived support and suicidality.

RESULTS

Cross-sectional results indicated that youths with higher perceived support were less likely to have suicidal ideation. Longitudinal results showed that youths with higher perceived support at Wave 1 were less likely to have suicidal ideation or serious suicide attempts at Wave 2. Transitional model results revealed that higher perceived support at Wave 1 was negatively associated with escalation in suicidal outcomes from Wave 1 to 2.

CONCLUSION

We discuss findings in the context of theories of suicide and discuss implications for suicide risk identification, intervention, and prevention efforts in late adolescence and emerging adulthood.

Alterations of regional spontaneous neuronal activity and corresponding brain circuits related to non-suicidal self-injury in young adults with major depressive disorder

BACKGROUND

Major depressive disorder (MDD) with non-suicidal self-injury (NSSI)(MDD/NSSI) has been found to differ from simple MDD without NSSI (sMDD). This study analyzes the amplitude of low-frequency fluctuations (ALFF) to explore the NSSI-relevant local neural activity, and uses functional connectivity (FC) analysis to explore the NSSI-relevant circuits corresponding to alterations in local regions in young adult patients with MDD/NSSI.

METHODS

A total of 54 patients with MDD/NSSI, 68 patients with sMDD, and 66 matched healthy controls (HCs) were recruited. ALFF and seed-based FC analyses were employed. The NSSI-relevant brain alteration and its associations with clinical variables were examined.

RESULTS

Compared with the sMDD group, the MDD/NSSI group showed higher ALFF in the right lingual gyrus and right middle occipital gyrus; lower ALFF in the right superior frontal gyrus; higher FC values between the right lingual gyrus and left precentral gyrus; and lower FC values between the right middle occipital gyrus and right paracentral gyrus. Within the MDD/NSSI group, ALFF values of the right superior frontal gyrus and right lingual gyrus were positively correlated with the frequency and severity of NSSI.

LIMITATIONS

The sample size was small, and the potential influence of medicine on brain activity was not excluded.

CONCLUSIONS

Our preliminary findings indicate that NSSI-relevant ALFF in the right lingual gyrus, right middle occipital gyrus, and right superior frontal gyrus, as well as the alteration FCs in corresponding brain circuits, may play an important role in the neural basis of MDD/NSSI.

Adolescent health outcomes: associations with child maltreatment and peer victimization

Background

Child maltreatment (CM) and peer victimization (PV) are serious issues affecting children and adolescents. Despite the interrelatedness of these exposures, few studies have investigated their co-occurrence and combined impact on health outcomes. The study objectives were to determine the overall and sex-specific prevalence of lifetime exposure to CM and past-month exposure to PV in adolescents, and the impact of CM and PV co-occurrence on non-suicidal self-injury, suicidality, mental health disorders, and physical health conditions.

Methods

Adolescents aged 14–17 years (n = 2,910) from the 2014 Ontario Child Health Study were included. CM included physical, sexual, and emotional abuse, physical neglect, and exposure to intimate partner violence. PV included school-based, cyber, and discriminatory victimization. Logistic regression was used to compare prevalence by sex, examine independent associations and interaction effects in sex-stratified models and in the entire sample, and cumulative effects in the entire sample.

Results

About 10% of the sample reported exposure to both CM and PV. Sex differences were as follows: females had increased odds of CM, self-injury, suicidality, and internalizing disorders, and males had greater odds of PV, externalizing disorders, and physical health conditions. Significant cumulative and interaction effects were found in the entire sample and interaction effects were found in sex-stratified models, indicating that the presence of both CM and PV magnifies the effect on self-injury and all suicide outcomes for females, and on suicidal ideation, suicide attempts, and mental health disorders for males.

Conclusions

Experiencing both CM and PV substantially increases the odds of poor health outcomes among adolescents, and moderating relationships affect females and males differently. Continued research is needed to develop effective prevention strategies and to examine protective factors that may mitigate these adverse health outcomes, including potential sex differences.

Core self-evaluation as mediator between depressive symptoms and suicidal ideation in adolescents

OBJECTIVES

To explore the role of core self-evaluation in mediating between depressive symptoms and suicidal ideation in Chinese adolescents.

METHODS

We used the cluster sampling method to analyze 11,563 students from five primary and secondary schools in China for depressive symptoms, core self-evaluation, and suicidal ideation using the following scoring scales: Core Self-Evaluation Scale (CSES), Center for Epidemiologic Survey Depression Scale (CES-D), the Second Edition of the Beck Depression Inventory (BDI- II), Screen for Child Anxiety Related Emotional Disorders (SCARED), and Adolescent Self-Rating Life Events Checklist (ASLEC).

RESULTS

The incidence of depression was 29.7%; anxiety, 34.2%; and suicidal ideation, 28.0%. Core self-evaluation was a protective factor for suicidal ideation [OR 0.947, 95% CI 0.937-0.959, p<0.001]. Conversely, depression as measured by the CSES score was a risk factor for suicidal ideation (OR 1.084, 95% CI 1.073-1.096, p<0.001), as were anxiety as measured by the SCARED score (OR 1.011, 95% CI 1.006-1.016, p<0.001) and adolescent life events according to ASLEC score groups (OR 1.524, 95% CI 1.434-1.621, p<0.001). Core self-evaluation mediated the relationship between depression and suicidal ideation with an effect size of 13.9%.

CONCLUSIONS

Better core self-evaluation is a protective factor against suicidal ideation and mediates the relationship between depression and suicidal ideation. We may be able to reduce the risk of suicidal ideation and therefore suicide among adolescents by improving their core self-evaluation.

The syndemic effects of adverse mental health conditions and polysubstance use on being at risk of clinical depression among marginally housed and homeless transitional age youth living in San Francisco, California

The objective of this study was to identify the correlates of being at risk of clinical depression and examine the role of syndemic factors among marginally housed and homeless transitional age youth (TAY). From 2017-2018, 100 TAY between the ages of 18 and 24 in San Francisco were recruited from Larkin Street Youth Services into a cross-sectional study. Participants completed surveys on mental health, substance use, and HIV risk behaviors. A syndemic score ranging from 0-3 was calculated by summing dichotomous measures of moderate or severe anxiety in the past two weeks, PTSD symptoms in the past month and polysubstance use in the past three months. We used modified Poisson regression with robust error variances to identify the correlates of being at risk of clinical depression in the past week, all primary effects measures were modeled separately. Among 100 participants, the average age was 21 (SD = 1.7), 67% were male, 38% were Multiracial, 54% identified as gay, lesbian, bisexual or pansexual, 13% were unstably housed, 50% were homeless and 23% were living with HIV. The majority (74%) were at risk of clinical depression, 51% had symptoms of moderate or severe anxiety, 80% exhibited symptoms of PTSD and 33% reported polysubstance use. After controlling for age in years, gender, race/ethnicity and sexual orientation, factors independently associated with being at risk of clinical depression were; symptoms of moderate or severe anxiety (adjusted risk ratio [aRR] = 1.62, 95% confidence interval [CI] = 1.23-2.12, P<0.001), symptoms of PTSD (aRR = 3.78, 95% CI = 1.58-9.04, P = 0.003), polysubstance use (aRR = 1.33, 95% CI = 1.06-1.68), P = 0.012), an increasing syndemic score (aRR = 1.40, 95% CI = 1.21-1.62), P<0.001), and having one, two or three syndemic factors (compared to none); (aRR = 2.68, 95% CI = 1.08-6.65, P = 0.032), (aRR = 3.24, 95% CI = 1.24-7.83, P = 0.003) and (aRR = 3.97, 95% CI = 1.65-9.52, P = 0.002), respectively. Integrated behavioral health models that treat co-occurring disorders simultaneously are needed to reduce syndemic risk among marginally housed and homeless TAY.

Twenty-six years of psychosocial interventions to reduce suicide risk in adolescents: Systematic review and meta-analysis

BACKGROUND

During adolescence, suicide risk increases; effective treatments are needed to reduce risk.

METHODS

Databases were searched (1995-2020) for randomized controlled trials (RCTs) concerning psychosocial treatments for suicide prevention in adolescents (10-18 yrs). Data were extracted from the timepoint closest to 6 months. Cohen's ds were estimated for reducing suicidal ideation (SI), self-harming behaviors (SHB) excluding strictly non-suicidal self-injury, and suicide attempts (SA) and analyzed using generalized least square regression. Meta-analytic innovations included within-person correlations to reflect trait suicidality; annualization to control for exposure; estimated lifetime risk based on ages; and modeling inclusion/exclusion criteria. Alternate approaches included relative risk and comparison of intervention and control treatments to baseline.

RESULTS

Of 30 RCTs, 6 assessing SHB (4 measuring SA), and 7 assessing SI demonstrated treatment effectiveness. Overall, interventions decreased SI (n = 25) with low effect size (d = 0.08, p = 0.01), non-significant after controlling for publication bias (d = 0.05, p = 0.1); interventions were non-significant for SHB (n = 25, d = 0.001, p = 0.97) or SA (n = 18, d = 0.03, p = 0.52). To prevent one SHB, the number needed to treat (NNT) was 45[26,156]; for SA, NNT=42[24,149]. Non-superiority may relate to effectiveness of control treatments. Thus, experimental and control treatments also were compared to baseline: both reduced SI (p < 0.0001), and effectiveness improved for SHB (NNT=12) and SA (NNT=11).

LIMITATIONS

Study heterogeneity and inconsistent statistical reporting limited meta-analysis.

CONCLUSIONS

Psychosocial interventions for suicide risk in adolescents showed little effectiveness compared with control treatments; suicide outcomes improved in both groups compared to baseline. Different approaches may be needed, including precision medicine methodologies and standardized statistical reporting criteria.

Differences in Comorbidities Between Children and Youth With Suicide Attempts Versus Ideation Presenting to the Emergency Department

OBJECTIVE

The aim of this work was to explore identified risk factors for suicidal ideations and attempts and the differences in these risk factors between emergency department encounters among youth seeking medical care for suicide attempt and those with suicidal ideation.

METHOD

This was a retrospective analysis of suicide-related claims for emergency department visits from nine state-level Healthcare Cost and Utilization Project databases for youth aged 5 through 19 years. Risk factors were estimated by identifying comorbidities recorded in first five diagnosis codes. Odds ratios comparing rates of these comorbidities in encounters for suicide attempts compared to encounters for suicidal ideation were estimated using multivariate logistic regression.

RESULTS

In all, 169,047 encounters for suicide-related behavior were identified. We found higher odds of concurrent anxiety, personality disorders, and alcohol-related diagnoses and lower odds of a comorbid psychosis diagnosis, attention deficit hyperactivity disorder, and other substance-related diagnoses in the population of suicide attempters compared to patients with suicidal ideation alone.

CONCLUSION

The odds of diagnoses of specific comorbidities differed in youth encounters for suicide attempts compared to encounters for suicidal ideation.

Applications of Aspect-based Sentiment Analysis on Psychiatric Clinical Notes to Study Suicide in Youth

Understanding and identifying the risk factors associated with suicide in youth experiencing mental health concerns is paramount to early intervention. 45% of patients are admitted annually for suicidality at BC Children's Hospital. Natural Language Processing (NLP) approaches have been applied with moderate success to psychiatric clinical notes to predict suicidality. Our objective was to explore whether machine-learning-based sentiment analysis could be informative in such a prediction task. We developed a psychiatry-relevant lexicon and identified specific categories of words, such as thought content and thought process that had significantly different polarity between suicidal and non-suicidal cases. In addition, we demonstrated that the individual words with their associated polarity can be used as features in classification models and carry informative content to differentiate between suicidal and non-suicidal cases. In conclusion, our study reveals that there is much value in applying NLP to psychiatric clinical notes and suicidal prediction.

Childhood Trauma increases suicidal behaviour in a treatment-resistant depression population: a FACE-DR report

OBJECTIVE

In addition to heredity, exposure to early-life adversity is an important predisposing risk factor of suicidal behaviour. Although the association between Childhood Trauma (CT) and suicide risk is well documented, interactions between CT and suicidal behaviour in Treatment-Resistant Depression (TRD) populations have received little coverage. This study aimed to evaluate i) association between CT and suicidal behaviour in a TRD population, and ii) the role of personality traits and impulsiveness as potential factors of mediation in these associations.

METHODS

Patients were recruited from a cohort of the French network of TRD expert centers. Depressive symptom severity, CT, suicidal behaviour, personality traits, and impulsiveness were assessed with the Montgomery-Åsberg Depression Rating Scale (MADRS), the Childhood Trauma Questionnaire (CTQ), the Columbia Suicide Severity Rating Scale (CSSRS), the Structured Clinical Interview for DSM-IV, the Big Five Inventory, and the Barratt Impulsivness Scale (BIS) respectively.

RESULTS

Among the 256 patients with a baseline CTQ, in relation to suicide risk for the current depressive episode, we found an association with the total CTQ scores mediated by the intensity of the current episode in a model adjusted for age and sex (total effect: β = 0.171; p = 0.011, direct effect: β = 0.135; p = 0.043; indirect effect: β = 0.036; p = 0.048). Focusing on CT subtypes, we detected an association between suicide risk and physical neglect in a model adjusted for age and sex (β = 0.301; p = 0.002), without any mediation by the intensity of the current episode. There was no mediation effect from personality traits nor impulsiveness. With regards to CSSRS to assess suicidal ideation, we did not find any association with the total CTQ score and CT subtype scores.

CONCLUSION

We report a strong association between suicidal behaviour and CT (in particular childhood physical neglect) in a TRD population.

Distinguishing prisoners who think about suicide from those who attempt suicide

BACKGROUND

Many people who consider suicide do not translate these intentions into action. Although prisoners constitute a particularly high-risk group for suicide, little is known about the factors that distinguish those who think about suicide from those who attempt suicide.

METHODS

Participants were 1326 adult offenders (1203 men) randomly selected from 15 Belgian prisons, representing 14% of the national prison population. Multivariate regression analysis compared prisoners who attempted suicide (n = 277) with those who thought about suicide but never made an attempt (n = 312) on a range of established risk factors.

RESULTS

Among the 589 participants reporting a lifetime history of suicidal ideation (44% of the total sample), almost half (47%) had made a suicide attempt. Relative to those who only thought about suicide, participants who attempted suicide were more likely to be violent offenders (aOR 2.33, 95% CI 1.49-3.62) and have a history of non-suicidal self-injury (aOR 3.19, 95% CI 2.09-4.86). The presence of self-reported mental disorder diagnosis (aOR = 2.84, 95% CI 1.91-4.24) and illicit substance abuse (aOR = 2.01, 95% CI 1.24-3.28) also independently differentiated prisoners who attempted v. considered suicide.

CONCLUSION

This study provides preliminary evidence that behavioural and mental health factors are implicated in the transition from thoughts to acts of suicide in prisoners. Prospective studies are warranted to explore whether these risk factors predict progression from ideation to action over time.

Non-suicidal self-injury and its co-occurrence with suicidal behavior: An epidemiological-study among adolescents and young adults

OBJECTIVE

Non-suicidal self-injury (NSSI) comprising thoughts and behaviors is common and often co-occurring with suicidal behavior like ideation, plan, and attempt. As limited data are available for adolescents and young adults, this study aims to present prevalence estimates for lifetime NSSI, its co-occurrence with suicidal behavior, conditional probabilities and their association with socio-demographic characteristics, severity characteristics of suicidal behavior, and health service utilization.

METHOD

The epidemiological Behavior and Mind Health (BeMIND) study assessed in 2015/16 a random-community sample of N = 1180 aged 14-21 years from Dresden, Germany, regarding lifetime NSSI via self-administered questionnaire and suicidal behaviors via standardized interview.

RESULTS

Any lifetime NSSI was reported by 19.3% (thoughts: 18.0%, behaviors: 13.6%) of the sample with higher prevalence in females (OR = 2.7, 95% CI 1.9-3.8, P < 0.001). Lifetime prevalence of co-occurring NSSI and suicidal behavior was 7.7%. Females had a 3.3- to 8.8-fold odds of co-occurrence than males. Among those with any NSSI, 39.6% endorsed suicidal behavior, and 66.3% of those with any suicidal behavior reported NSSI. 42.3% of those with any NSSI reported to have used mental healthcare services at any time during their life with higher rates in those with co-occurring suicidal behavior (62.3%).

CONCLUSION

Non-suicidal self-injury and co-occurring suicidal behavior is common in adolescents and young adults-especially females. The limited utilization of mental healthcare services underpins the need for improving recognition of NSSI and suicidal behavior as well as the accessibility of mental healthcare services during adolescence and emerging adulthood.

Differentiating Adolescent Suicide Attempters and Ideators: A Classification Tree Analysis of Risk Behaviors

PURPOSE

Although many youth consider suicide, only a subset act on suicidal thoughts and attempt suicide. The objective of this study was to identify patterns of risk factors that differentiate adolescents who experienced suicidal thoughts from those who attempted suicide.

METHODS

This study analyzed data from the 2013, 2015, and 2017 National Youth Risk Behavior Surveys. Classification tree analysis was used to identify combinations of health risk behaviors and demographic factors that improved the identification of past-year suicide attempts among adolescents with past-year suicide ideation or planning (overall n = 7,493).

RESULTS

Forty percent of the past-year ideators attempted suicide in the same period. The best-performing tree included three variables and defined four subgroups. Youth characterized by heroin use and past-year physical fights were at a strikingly high risk of being attempters (78%). Youth who had experienced rape were also likely to be attempters (58%), whereas those who had endorsed none of these three variables were relatively less likely to be attempters (29%). Overall, the tree's classification accuracy was modest (area under the curve = .65).

CONCLUSIONS

This study advances previous research by identifying notable constellations of risk behaviors that accounted for adolescents' transition from suicidal ideation to behavior. However, even with many health risk behavior variables, a large sample, and a multidimensional analytic approach, the overall classification of suicide attempters among ideators was limited. Implications for future research are discussed.

Factors associated with the transition from suicidal ideation to suicide attempt in prison

BACKGROUND

Although research has identified a wide range of risk factors for suicidal behavior in prisoners, it does not establish who is most likely to act on their suicidal thoughts while incarcerated.

METHODS

Self-report data were collected from a random sample of 1,203 adult men incarcerated across 15 prisons in Belgium, who represent 12% of all male prisoners nationwide.

RESULTS

One-third (33%) of participants reported having suicidal thoughts during their incarceration, of whom 26% attempted suicide in prison (9% of all prisoners). Factors independently associated with suicide attempt among prisoners with suicidal ideation were violent offending (adjusted odds ratio [aOR] = 2.64, 95% confidence interval [CI] 1.33-5.23), in-prison drug use (aOR = 2.30, 95% CI 1.25-4.22), exposure to suicidal behavior (aOR = 1.96, 95% CI 1.04-3.68), and a lifetime history of nonsuicidal self-injury (aOR = 1.90, 95% CI 1.08-3.36). While related to suicidal thoughts, markers of psychiatric morbidity and aspects of the prison regime were not associated with the progression to suicide attempt.

CONCLUSIONS

Many prisoners who think about suicide do not attempt suicide while incarcerated. Factors associated with suicidal ideation are distinct from those that govern the transition to suicidal behavior. Our findings lend support to the hypothesis that behavioral disinhibition might act as a catalyst in the translation of suicidal thoughts into action.

Social rejection, popularity, peer victimization, and self-injurious thoughts and behaviors among adolescents: A systematic review and meta-analysis

Self-injurious thoughts and behaviors (SITBs) are significant public health problems in adolescence. The current article provides a comprehensive systematic review examining the relationship between events leading to perceived low relational evaluation (e.g. social rejection) and SITBs among adolescents. Theoretical work posits that low relational evaluation is experienced as psychologically painful, a known correlate of SITBs. Therefore, events leading to low relational evaluation may be particularly informative in understanding the context of SITBs. The current review examines how experiences of low relational evaluation that are hypothesized to elicit psychological pain, such as social rejection, low popularity, and peer victimization are related to engagement in SITBs in adolescence. A total of 56 articles meeting inclusion criteria were identified. The hypothesis of an association between indicators of low relational evaluation and SITBs was generally supported throughout the literature, with more consistency found among studies examining suicidal ideation specifically. However, interpretation of the findings is constrained by various methodological limitations of studies. The present review concludes with a theoretical conceptualization of the relationship between perceived relational value and SITBs, leveraging social and evolutionary psychological theory, to guide future research into this topic.

Adolescents' knowledge of a peer's non-suicidal self-injury and own non-suicidal self-injury and suicidality

OBJECTIVE

Some research suggests that suicidal ideation and attempt among adolescents may be contagious - that is adolescents who are exposed to peers' suicidal behaviour are more likely to experience suicidal ideation or attempt suicide themselves. Less is known about the potential contagion effect of non-suicidal self-injury (NSSI). Our objective was to determine whether knowledge of a friend's NSSI is associated with adolescent's own non-suicidal self-injury and suicidal behaviours.

METHODS

Data from 1483 youth ages 14-17 years were obtained from the 2014 Ontario Child Health Study, a cross-sectional population-based survey of children and adolescents in Ontario, Canada. Logistic regression models were used to examine associations between knowledge of a friend's NSSI and adolescents' own self-reported self-injurious and suicidal behaviours. Interactions with gender, age group and presence of a mental disorder were investigated.

RESULTS

Knowledge of a friend's non-suicidal self-injury was significantly associated with the adolescent's own non-suicidal self-injury (OR = 2.03, 95% CI 1.05-3.90), suicidal ideation (OR = 3.08, 95% CI 1.50-6.30) and suicide attempt (OR = 2.87, 95% CI 1.20-6.87).

CONCLUSION

These findings suggest an apparent contagion effect for non-suicidal self-injury. Awareness of a friend's self-injurious behaviours is associated with an adolescent's own self-injury and suicidality. Interventions aimed at preventing NSSI and suicidality should consider prevention of possible contagion at the school and/or community level.

Recruitment of adolescents with suicidal ideation in the emergency department: lessons from a randomized controlled pilot trial of a youth suicide prevention intervention

BACKGROUND

Emergency Departments (EDs) are a first point-of-contact for many youth with mental health and suicidality concerns and can serve as an effective recruitment source for randomized controlled trials (RCTs) of mental health interventions. However, recruitment in acute care settings is impeded by several challenges. This pilot RCT of a youth suicide prevention intervention recruited adolescents aged 12 to 17 years presenting to a pediatric hospital ED with suicide related behaviors.

METHODS

Recruitment barriers were identified during the initial study recruitment period and included: the time of day of ED presentations, challenges inherent to study presentation, engagement and participation during an acute presentation, challenges approaching and enrolling acutely suicidal patients and families, ED environmental factors, and youth and parental concerns regarding the study. We calculated the average recruitment productivity for published trials of adolescent suicide prevention strategies which included the ED as a recruitment site in order to compare our recruitment productivity.

RESULTS

In response to identified barriers, an enhanced ED-centered recruitment strategy was developed to address low recruitment rate, specifically (i) engaging a wider network of ED and outpatient psychiatry staff (ii) dissemination of study pamphlets across multiple areas of the ED and relevant outpatient clinics. Following implementation of the enhanced recruitment strategy, the pre-post recruitment productivity, a ratio of patients screened to patients randomized, was computed. A total of 120 patients were approached for participation, 89 (74.2%) were screened and 45 (37.5%) were consented for the study from March 2018 to April 2019. The screening to randomization ratio for the study period prior to the introduction of the enhanced recruitment strategies was 3:1, which decreased to 1.8:1 following the implementation of enhanced recruitment strategies. The ratio for the total recruitment period was 2.1:1. This was lower than the average ratio of 3.2:1 for published trials.

CONCLUSIONS

EDs are feasible sites for participant recruitment in RCTs examining new interventions for acute mental health problems, including suicidality. Engaging multi-disciplinary ED staff to support recruitment for such studies, proactively addressing anticipated concerns, and creating a robust recruitment pathway that includes approach at outpatient appointments can optimize recruitment.

Mental disorders and risk of suicide attempt in prisoners

BACKGROUND

Mental disorders are overrepresented in prisoners, placing them at an increased risk of suicide. Advancing our understanding of how different mental disorders relate to distinct stages of the suicidal process-the transition from ideation to action-would provide valuable information for clinical risk assessment in this high-risk population.

METHODS

Data were drawn from a representative sample of 1212 adults (1093 men) incarcerated across 13 New Zealand prisons, accounting for 14% of the national prison population. Guided by an ideation-to-action framework, three mutually exclusive groups of participants were compared on the presence of mental disorders assessed by validated DSM-IV diagnostic criteria: prisoners without any suicidal history (controls; n = 778), prisoners who thought about suicide but never made a suicide attempt (ideators; n = 187), and prisoners who experienced suicidal ideation and acted on such thoughts (attempters; n = 247).

RESULTS

One-third (34.6%) of participants reported a lifetime history of suicidal ideation, of whom 55.6% attempted suicide at some point (19.2% of all prisoners). Suicidal outcomes in the absence of mental disorders were rare. Whilst each disorder increased the odds of suicidal ideation (OR range 1.73-4.13) and suicide attempt (OR range 1.82-4.05) in the total sample (n = 1212), only a select subset of disorders was associated with suicide attempt among those with suicidal ideation (n = 434). Drug dependence (OR 1.65, 95% CI 1.10-2.48), alcohol dependence (OR 1.89, 95% CI 1.26-2.85), and posttraumatic stress disorder (OR 2.09, 95% CI 1.37-3.17) distinguished attempters from ideators.

CONCLUSION

Consistent with many epidemiological studies in the general population, our data suggest that most mental disorders are best conceptualized as risk factors for suicidal ideation rather than for suicide attempt. Once prisoners consider suicide, other biopsychosocial factors beyond the mere presence of mental disorders may account for the progression from thoughts to acts of suicide.

Mental Health Problems and Risk of Suicidal Ideation and Attempts in Adolescents

BACKGROUND

Obtaining recent estimates of the prevalence of suicide-related outcomes across adolescence and its associated mental health problems (MHPs) is important for clinical practice. We estimated the prevalence of suicide-related outcomes at ages 13, 15, 17, and 20 years (2011-2018) in a contemporary population-based cohort and documented associations with MHPs throughout adolescence.

METHODS

Data came from 1618 participants in the Québec Longitudinal Study of Child Development. Internalizing (depression and anxiety) and externalizing (oppositional/defiance, conduct issues, and attention deficit and/or hyperactivity) MHPs were assessed with validated questionnaires. Outcomes were self-reported past-year passive and serious suicidal ideation and suicide attempt.

RESULTS

Lifetime prevalence of passive suicidal ideation (13-17 years old), serious suicidal ideation, and suicide attempt (13-20 years old) were 22.2%, 9.8%, and 6.7%, respectively. Prevalence was twice as high for females as for males. Overall, rates of passive (15-17 years old; 11.8%-18.4%) and serious ideation (13-20 years old; 3.3%-9.5%) increased over time but were stable for attempt (13-20 years old; 3.5%-3.8%). In univariable analyses, all MHPs were associated with suicide-related outcomes at all ages (risk rate ratio range: 2.57-3.10 [passive ideation] and 2.10-4.36 [suicide attempt]), and associations were similar for male and female participants (sex interaction P > .05). Magnitude of associations were generally stronger for more severe suicide-related outcomes (passive ideation < serious ideation < attempt). In multivariable analyses, internalizing problems were associated with suicidal ideation, whereas both depressive and conduct symptoms were associated with attempt.

CONCLUSIONS

Suicidal ideation and attempt were common, especially for females and youth presenting with depressive and conduct problem symptoms. Clinicians should systematically assess suicidal risk in teenagers, especially in those presenting with MHPs.

Cannabis Use and Internalizing/Externalizing Symptoms in Youth: A Canadian Population-Based Study

PURPOSE

With the recent legalization of cannabis for nonmedicinal purposes in Canada, it is becoming increasingly important to understand the potential mental health risks that cannabis may present. The objective of this study was to estimate associations between the frequency of cannabis use and the presence of elevated internalizing (e.g., anxiety and depression) and externalizing (e.g., conduct disorder and attention deficit hyperactivity disorder) symptoms within Ontario youth aged 12-17 years.

METHODS

The 2014 Ontario Child Health Study included Emotional and Behavioural Scales used to assess internalizing and externalizing symptoms. To assess associations between internalizing/externalizing symptoms and cannabis use, the Ontario Child Health Study-Emotional and Behavioural Scales were dichotomized using the upper quintile (those with the most severe symptoms). Logistic regression was used to estimate odds ratios (ORs) to quantify the association between the frequency of cannabis use and the presence of elevated internalizing and externalizing symptoms. Estimates used a recommended procedure (replicate bootstrap weighting) to address design effects.

RESULTS

A significant association between frequent cannabis use and elevated externalizing symptoms was observed with an OR of 2.17 (1.80-2.62) in males and 5.13 (4.24-6.21) in females. Similar significant associations were also observed between frequent cannabis use and elevated internalizing symptoms with an OR of 2.07 (1.74-2.47) in males and an OR of 3.40 (2.73-4.24) in females. These associations were still present after adjusting for age, binge drinking, smoking, and negative/positive parenting.

CONCLUSIONS

Cannabis use, especially in females and frequent users, is associated with elevated levels of internalizing and externalizing symptoms.

"Objectively terrifying": a qualitative study of youth's experiences of transitions out of child and adolescent mental health services at age 18

BACKGROUND

Mental health issues presenting in childhood often persist into adulthood, usually requiring youth to transition from child and adolescent mental health services to adult mental health services at 18 years. Discontinuity of care during this transition period is well-documented and can leave youth vulnerable to adverse mental health outcomes. There is growing recognition of the need to improve transition-related care for youth leaving the child and adolescent mental health system. However, the perspectives and experiences of youth have not always been forefront in these discussions, and in particular, the perspectives of youth in the pre-transition period. This study qualitatively explores transition-related knowledge and experiences of youth both prior-to and after transition.

METHODS

A purposive sample of youth aged 16-19 years was recruited from two child and adolescent mental health programs. Youth were enrolled as part of a longitudinal follow-up study and had the opportunity to opt into this study. Interviews were transcribed and coded using NVivo11 software. Main themes were distilled through descriptive analysis following the principles of directed content analysis. The study followed the principles of participatory action research, engaging youth with lived experience navigating transitions in each stage of the study.

RESULTS

In-depth, semi-structured interviews were conducted with 14 pre-transition and 8 post-transition youth. All youth reported having either a mood and/or anxiety disorder for which the majority were receiving treatment at the time of the interview. The participants' experiences were distilled into six major themes. Youth advocated for being considered partners in transition planning and to have increased control over transition-related decisions. Youth also made specific recommendations on how to improve continuity of care during the transition process.

CONCLUSIONS

Transition planning should be individualized for each youth based on their developmental needs, transition readiness and ongoing mental health needs. Transition pathways, co-designed with youth and caregivers, should be developed to guide providers in transition best practices. Obtaining both the pre- and post-transition experiences of youth is crucial for developing a more complete of understanding of youth perspectives and implementing guidelines that improve transition quality and experiences.

Service provision for depressed children and youth: a survey of the scope and nature of services in Ontario

BACKGROUND

The worldwide prevalence of depressive disorders among children and youth has been reported in ranges from just under 3% to over 10%. In Canada, 7% of youth report past year depression, which is higher than any other age demographic. Yet, many of these youth do not receive evidence based interventions, increasing their risk for serious lifetime consequences. To better understand low service use, it is crucial to map and evaluate current services. This study aimed to determine the scope and nature of services available to depressed children and youth, and compare services to best evidence treatment guidelines.

METHODS

Several government and non-government resources were utilized to develop a new multi-sectoral database of depression services for children and youth across Ontario. An online survey was sent to program managers serving children/youth with depression, examining agency characteristics, populations served, services provided, patterns of service use, evaluation activities, and research priorities.

RESULTS

413 agencies with 869 program managers participated, representing mental health, addictions and other sectors. Age groups served included children up to 12 years of age (31%), adolescents aged 13-17 (70%) and transition aged youth (18-25 years) (81%). Over half of respondents worked in the mental health (43.4%) or mental health and addiction (24.4%) sectors. The most frequently provided services were assessment, psychotherapy, case management, and psychoeducation; the most common types of psychotherapy provided included cognitive behavioral therapy, social skills training, and solution-focused therapy. Psychotherapies are offered in widely varying formats, frequencies and durations. Discontinuation rates varied, with higher discontinuation among transition aged youth as compared to children. Respondents identified effective treatment, improving access, and reducing service gaps as top future research priorities.

CONCLUSIONS

This study provides important new data on service provision and uptake for depressed children and youth. Comparing these results with best-evidence practice guidelines raises significant concerns about the services most commonly offered and their delivery formats. In addition, high early discontinuation rates raise questions about the service experiences of children, youth and their families. Other factors which may contribute to ongoing treatment engagement challenges include access barriers, service or client characteristics, and unintentional treatment impacts.

Multimorbidity in Children and Youth Across the Life-course (MY LIFE): protocol of a Canadian prospective study

INTRODUCTION

Multimorbidity, the co-occurrence of a chronic physical condition and mental disorder, affects a substantial number of children and youth and can lead to compromised quality of life, hardship for families, and an increased burden on the healthcare system. We are conducting a study to document the course of mental disorder in children and youth diagnosed with a chronic physical condition; identify predictors of child and youth multimorbidity; examine whether the effects of these predictors are moderated by relevant psychosocial and biological factors; explore potential inflammatory and stress biomarkers that mediate the onset of child and youth multimorbidity; and, assess whether multimorbidity in children and youth alters patterns of mental health service use.

METHODS AND ANALYSIS

Multimorbidity in Children and Youth Across the Life-course (MY LIFE) is a prospective study. Two hundred and fifty children and youth aged 2-16 years diagnosed with a chronic physical condition along with one parent will be recruited from the outpatient clinics at a paediatric tertiary care centre. Data will be collected using a multi-informant, multimethod design at four time-points (at recruitment, and at 6, 12 and 24 months postrecruitment). Parents will provide reports for all children/youth. In addition, youth ≥10 years will self-report. Mental disorder will be assessed using structured interviews. On completion of data collection, participant-reported data will be linked to provincial health records to identify mental health services use. Multilevel analyses (survival, proportional hazard, structural equation modelling) will be used to address MY LIFE objectives.

ETHICS AND DISSEMINATION

This study has been approved by the University of Waterloo Human Research Ethics Board and the Hamilton Integrated Research Ethics Board. Findings will be disseminated to key stakeholders using a number of outlets (peer-reviewed publications and conferences, lay informational pamphlets, social media).

Changing Rates of Self-Harm and Mental Disorders by Sex in Youths Presenting to Ontario Emergency Departments: Repeated Cross-Sectional Study

OBJECTIVE

To document the rates of intentional self-harm and mental disorders among youths aged 13 to 17 years visiting Ontario emergency departments (EDs) from 2003-2017.

METHODS

This was a repeated cross-sectional observational design. Outcomes were rates of adolescents with (1) at least 1 self-harm ED visit and (2) a visit with a mental disorder code.

RESULTS

Rates of youths with self-harm visits fell 32% from 2.6/1000 in 2003 to 1.8 in 2009 but rose 135% to 4.2 by 2017. The slope of the trend in self-harm visits changed from -0.18 youths/1000/year (confidence interval [CI], -0.24 to -0.13) during 2003 to 2009 to 0.31 youths/1000/year (CI, 0.27 to 0.35) during 2009 to 2017 (P < 0.001). Rates of youths with mental health visits rose from 11.7/1000 in 2003 to 13.5 in 2009 (15%) and to 24.1 (78%) by 2017. The slope of mental health visits changed from 0.22 youths/1000/year (CI, 0.02 to 0.42) during 2003 to 2009 to 1.84 youths/1000/year (CI, 1.38 to 2.30) in 2009 to 2017 (P < 0.001). Females were more likely to have self-harm (P < 0.001) and mental health visits (P < 0.001). Rates of increase after 2009 were greater for females for both self-harm (P < 0.001) and mental health (P < 0.001).

CONCLUSIONS

Rates of adolescents with self-harm and mental health ED visits have increased since 2009, with greater increases among females. Research is required on the determinants of adolescents' self-harm and mental health ED visits and how they can be addressed in that setting. Sufficient treatment resources must be supplied to address increased demands for services.

Non-suicidal self-injury and co-occurring suicide attempt in male prisoners

High rates of non-suicidal self-injury (NSSI) and suicide attempts (SA) are well documented in prisoners, however, few studies examined their co-occurrence in this high-risk population. Study participants were 1203 adult men randomly selected from 15 Belgian prisons, representing 12% of the national male prison population. Lifetime prevalence rates for NSSI and SA are 17% and 20% respectively, with half (55%) of self-injurers reporting a SA history. Bivariate analyses show that NSSI and SA are significantly related to one another, and many risk factors are common to both. Multivariate analysis comparing prisoners who engaged in NSSI with (n = 109) and without (n = 90) co-occurring SA indicates that suicidal ideation is the strongest independent correlate of SA among self-injurers. Additionally, relative to those with a history of NSSI only, prisoners with co-occurring NSSI and SA are significantly more likely to be violent offenders, being prescribed psychotropic medication, and report a psychiatric diagnosis; suggesting that they constitute a more clinically severe subgroup. Collectively, these findings highlight the marked overlap between NSSI and SA in prisoners, both in terms of prevalence and correlates, with suicidal ideation being an important predictor of suicide risk among self-injurers.
