Multiple substance use and self-reported suicide attempts by adolescents in 16 European countries

Adolescent behavioural risk screening in primary care: physician's point of view

BACKGROUND

Despite regular consultation between adolescents/young adults (AYA) and their physicians, they are not regularly screened for psychosocial risk behaviours. This study examines physicians' self-reported psychosocial risk behaviour screening in AYA. It aims to highlight which elements hinder or improve screening abilities.

METHODOLOGY

The design was a cross-sectional quantitative survey. Data were obtained through a self-reported questionnaire sent out to primary care physicians (PCP) in Switzerland in 2018. The target population consisted of 1,824 PCP (29% response rate). Participants were asked whether they screened youths from 3 age groups [10-14 y/o, 15-20 y/o, and 21-25y/o] for the HEEADSSS items during child well visits and routine checkups. Barriers to screening included primary consultation motive prioritization, insufficient time, patient compliance, reimbursement, lack of skills related to adolescent health, lack of referral options. Data were analysed first through a bivariate analysis using Chi-square tests then through a multinomial logistic regression.

RESULTS

The majority of physicians partook in preventive screening for 3-5 psychosocial risk elements. They reported the primary consultation motive as well as a lack of available time as having a high impact on their screening habits. Physician's experience and having discussed confidentiality were related to an increase in the number of topics addressed. Confidentiality remained a significant variable throughout all analyses.

CONCLUSION

Barriers such as lack of consultation time and prioritization issues were found by physicians to be critical but did not hinder screening habits. The main element impacting screening habits was assuring confidentiality and the second is self-efficacy.

Pathways From Bullying Victimization to Suicidal Thoughts Among Urban African American Adolescents: Applying the General Strain Theory

ABSTRACT

The present study explores the relationship between bullying victimization and suicidal thoughts among African American adolescents in urban neighborhoods. The study, which was guided by the general strain theory, proposed and tested potential pathways that link bullying victimization with suicidal thoughts through the mediators including emotional distress, low future orientation, hopelessness, and drug use. The study sample included 414 African American adolescents who were between ages 12 and 22 years and residing in low-income Chicago's South Side neighborhoods. Descriptive statistics, bivariate correlation, and path analyses were conducted. Bullying victimization was not significantly related to suicidal thoughts, although it was positively associated with emotional distress and drug use. The association between low future orientation and hopelessness was bidirectional. The study findings have implications for practice, which is important as resources to assist adolescents who are affected by violence tend to be limited.

Protective factors of suicidal behaviors in children and adolescents/young adults: A literature review

BACKGROUND

Suicidal behaviors present a public health challenge in children and adolescents. Although the risk factors have long been well documented, protective factors have only been documented for a few years, and there has not been a literature review concerning the suicidal behaviors of children and adolescents since 2006.

METHODS

Relevant articles were collected using the Medline/PubMed, Web of Science, and ScienceDirect databases. Studies meeting the following inclusion criteria were included: age of participants from 6 to 19 years, qualitative and quantitative cohort or case-control studies, multivariate analysis studies, and studies with significant results for at least one protective factor. The methodology used in this review is based on the PRISMA criteria.

RESULTS

A total of 26 studies were included in this review, which highlights various individual and environmental protective factors. The results were too heterogeneous to perform a meta-analysis, and therefore the discussion is in the form of a narrative summary. High-quality relationships with family and in the school environment were the most frequently found protective factors. The presence of positive links with peers, with other adults, and with the culture of origin was also noted. On an individual level, self-esteem, emotional intelligence, and particular coping abilities were found to be the most important protective factors.

CONCLUSION

There are numerous important protective factors for suicidal behaviors in children and adolescents and also for adapting care to their needs. A future challenge will be to determine the best protective factors to be consolidated or strengthened using self-assessment tools that are already in use or being developed.

Cannabis use disorder, suicide attempts, and self-harm among adolescents: A national inpatient study across the United States

BACKGROUND

Suicide is among the top three causes of adolescent mortality. There is a scarcity of research examining cannabis use and suicidal behavior in adolescents.

OBJECTIVES

To determine the association between cannabis use disorder (CUD) and suicide attempt/self-harm in a hospitalized sample of adolescents.

METHODS

We conducted a cross-sectional observation study using data from the Nationwide Inpatient Sample collected over four years from January 1, 2016, through December 31, 2019. We included adolescents aged 10-19 hospitalized during the above period (N = 807,105). The primary outcome was suicide attempt/self-harm and the main predictor was CUD. The International Classification of Diseases Tenth Revision (ICD 10) diagnostic codes was used to identify a diagnosis of CUD, suicide attempt/self-harm, and other diagnoses included in the analyses. Adolescents diagnosed with CUD (n = 53,751) were compared to adolescents without CUD (n = 753,354). Univariate and multivariate logistic regressions were conducted to determine the association between CUD and suicide attempts/self-harm.

RESULTS

807,105 adolescent hospitalizations were analyzed, of which 6.9% had CUD. Adolescents with CUD were more likely to be older (17 years vs. 15 years), female (52% vs. 48%), have depression (44% vs. 17%), anxiety (32% vs. 13%), an eating disorder (1.9% vs. 1.2%), ADHD (16.3% vs. 9.1%), Conduct Disorder (4.1% vs. 1.3%), Alcohol Use Disorder (11.9% vs. 0.8%), Nicotine Use Disorder (31.1% vs. 4.1%), Cocaine Use Disorder (5.4% vs. 0.2%), Stimulant Use Disorder (0.8% vs. 0.4%) and report suicide attempts/self-harm (2.8% vs. 0.9%) [all ps<0.001]. After adjusting for potential confounders, CUD was associated with a higher risk of suicide attempts/self-harm (OR = 1.4, 95% CI 1.3-1.6, p <0.001). Post-hoc analyses showed the presence of depression moderated the association between CUD and suicide attempts/self-harm in that adolescents with CUD and depression had 2.4 times the odds of suicide attempt/self-harm compared to those with CUD but no depression after controlling for potential confounders (p<0.001).

CONCLUSIONS

Our study provides evidence for the association between CUD and suicide risk among hospitalized adolescents and underscores the importance of recognizing and addressing co-occurring mental and substance use disorders along with CUD to mitigate suicide risk. Identifying high-risk adolescents in inpatient settings provides an opportunity for intervention.

Substance Use, Internet Risk Behavior, and Depressive Symptoms as Predictors of Self-harm Thoughts in Adolescents: Insights from the 2019 ESPAD Survey in Croatia

Self-harm has become a nonspecific symptom of mental distress that is most prevalent in the adolescent population. Since it is often a hidden problem, it is important to focus on preventing it. This study used the data from the Croatian leg of the European School Survey Project on Alcohol and Other Drugs to assess certain risk factors and possible protective factors for self-harm thoughts among 16-year-olds in Croatia. Using binary logistic regression, we identified that being female, having less family support and less parental knowledge of adolescents' activities, more frequent cannabis use, more compulsive Internet use and more frequent depressive symptoms significantly increased the likelihood of self-harm thoughts in this sample. Identifying factors that lead to thoughts of self-harm may open a potential space for self-harm prevention before those thoughts progress into behavior.

Associations Between Gender-Specific Substance Use Patterns and Mental Health Among Adolescents in the Republic of Korea: A Latent Class Analysis

PURPOSE

Although gender differences in adolescent substance use are complex and substance use accompanies mental health problems, most previous studies have focused on gender-specific association between single substance use and mental health. This study aimed to investigate gender-specific substance use patterns and to examine their association with mental health characteristics.

METHODS

Nationally representative data from the Korea Youth Risk Behavior Survey collected in 2018 were analyzed. To identify substance use patterns among male adolescents (n = 30,463) and female adolescents (n = 29,577), multiple-group latent class analysis was conducted using eight substance use indicators. In addition, we conducted a latent class analysis with covariates to examine the association between substance use patterns and mental health characteristics.

RESULTS

Among both gender samples, the four-class model best fit the data: nonusers (86.4%), frequent smokers (2.9%), risky drinkers (7.1%), and heavy tobacco and alcohol users with lifetime heated tobacco product use (3.6%) for male adolescents, and nonusers (89.8%), frequent smokers (0.5%), risky drinkers (8.0%), and heavy tobacco and alcohol users with a drunkenness episode (1.7%) for female adolescents. Depression, suicidal plans, and suicidal attempts predicted the latent class model for both genders. In addition, stress level predicted the latent class model for female adolescents.

CONCLUSIONS

The findings indicate that homogeneous patterns of substance use by gender are differentially associated with mental health problems. Therefore, health professionals should develop interventions tailored to gender-specific substance use patterns, taking into account the mental health characteristics of each pattern.

Compositional associations of time spent in sleep, screen time, and physical activity with polysubstance use in adolescents

This study of grade 6-10 students used compositional analysis to examine the relationship between the movement behavior composition (time in sleep, screen time, and physical activity) and polysubstance use (frequency of using cigarettes, alternative tobacco products, alcohol, cannabis, and illicit drugs). In grades 6-8 students and grades 9-10 girls: 1) sleep was negatively associated with polysubstance use, 2) screen time was positively associated with polysubstance use, and 3) reallocating physical activity or screen time into sleep was associated with lower polysubstance use. In grades 9-10 boys, reallocating 60 min/day from physical activity into screen time or sleep was associated with greater polysubstance use.

The science of child and adolescent mental health in Greece: a nationwide systematic review

Evidence-based information is essential for effective mental health care, yet the extent and accessibility of the scientific literature are critical barriers for professionals and policymakers. To map the necessities and make validated resources accessible, we undertook a systematic review of scientific evidence on child and adolescent mental health in Greece encompassing three research topics: prevalence estimates, assessment instruments, and interventions. We searched Pubmed, Web of Science, PsycINFO, Google Scholar, and IATPOTEK from inception to December 16th, 2021. We included studies assessing the prevalence of conditions, reporting data on assessment tools, and experimental interventions. For each area, manuals informed data extraction and the methodological quality were ascertained using validated tools. This review was registered in protocols.io [68583]. We included 104 studies reporting 533 prevalence estimates, 223 studies informing data on 261 assessment instruments, and 34 intervention studies. We report the prevalence of conditions according to regions within the country. A repository of locally validated instruments and their psychometrics was compiled. An overview of interventions provided data on their effectiveness. The outcomes are made available in an interactive resource online [ https://rpubs.com/camhi/sysrev_table ]. Scientific evidence on child and adolescent mental health in Greece has now been cataloged and appraised. This timely and accessible compendium of up-to-date evidence offers valuable resources for clinical practice and policymaking in Greece and may encourage similar assessments in other countries.

Suicidality Prevalence in a Pediatric Psychiatric Clinic: Relation to Social and Environmental Risk Factors

Suicidality is a growing public health problem in children and adolescents. The aim of this retrospective data analysis study was to estimate the prevalence of suicidality in pediatric patients admitted to an academic Pediatric Psychiatric Clinic (PPC) and to analyze social and environmental risk factors associated with suicide. Suicidal ideation was assessed by the Self-Injurious Thoughts and Behaviors Interview. Using established psychometric scales, social and stressful events were analyzed. During the four-year study, 249 episodes of care were experienced by 152 individuals (mean age 15.2 ± 2 years, girls/boys 107/45). Twenty-eight patients (11.2%) were admitted from the Pediatric Intensive Care Unit and the Department of Pediatrics, 162 (65.1%) from the Pediatric Emergency Department, and 59 (23.7%) from other Hospitals (p = 0.003). A significant longitudinal increase in admissions to PPC, with increasing trends of suicidal ideation, suicide attempts, and suicidality, was recorded. Suicidal behavior, bullying, internet addiction, friends quarreling, and family problems were risk factors for suicide attempts and suicidality. Our results have implications for prevention programs, highlighting an increasing need for care for suicide attempts and suicidal ideation, related to specific stressful events and contextual socio-environmental status.

Cannabis smoking increases the risk of suicide ideation and suicide attempt in young individuals of 11-21 years: A systematic review and meta-analysis

BACKGROUND

Cannabis is the most frequently consumed drug around the world. Its use has been associated with increased suicide behaviors; nonetheless, the association of cannabis smoking and suicide behaviors in adolescents has not yet been established. The aim of this systematic review and meta-analysis was to evaluate the risk of suicide attempt, suicidal ideation or suicide planning in individuals of 11-21 years of age who smoke cannabis.

METHODS

We performed an online searched using PubMed, EBSCO and Science Direct databases, up to July 2021. We calculated odds ratio with 95% confidence intervals to evaluate the association between suicide attempt, suicidal ideation or suicide planning and cannabis smoking in individuals of 11-21 years of age.

RESULTS

Twenty studies reported suicide attempts in 34,859 young individuals, suicidal ideation in 26, 937 individuals, and suicide planning in 9054 young individuals. We found an increased risk of suicide attempt in cannabis smokers than in non-cannabis users (OR: 2.33; 95% CI: 1.78-3.05; Z p value; <0.0001; I² = 97.12%), as well as a significant association between cannabis smoking and suicidal ideation (OR: 2.04; 95%CI: 1.64-2.53; Z p value: <0.001; I²: 94.88) and suicide planning (OR: 1.674; 95% CI: 1.554-1.804; Z p value: 0.000; I²: 92.609). Subgroup analyses showed that American teens have an increased risk of suicidal ideation; the meta-regression analysis revealed that age was negatively associated with the risk of suicide attempt.

CONCLUSIONS

This meta-analysis shows that cannabis smoking increased the risk of suicide attempt, suicidal ideation and suicide planning in young individuals of 11-21 years of age. The high risk of suicide behaviors could vary depending on the population studied; therefore, more studies are necessary to corroborate the risk of presenting suicide behaviors in individuals of 11-21 years of age who smoke cannabis.

Suicide ideation and/or attempt with substance use and associated factors among the youth in northwest Ethiopia, community-based

BACKGROUND

Substance use is referring to the use of psychoactive substances like chat, cigarettes, alcohol, and others. The use of substances particularly (alcohol, chat, and cigarette) is a major mental health burden in developing countries including Ethiopia among youth. Suicide ideation and an attempt are thinking or trying to kill oneself that facilitates the act of a person intentionally causing his or her death. Suicide is one of the most serious mental health problems and has a great social impact in the world as it is currently the third leading cause of death for youth. Youth is defined as the period of life between childhood and maturity with an age interval of (15-25).

METHOD

A cross-sectional study design was used to assess the prevalence of suicidal ideation and attempts with substance use among youth in northwest Ethiopia. Multi-stage sampling techniques of stratified with simple random sample ware used. In the first stage, substance users are selected then as the second stage among substance users the burden of suicide behavior is assessed. ASIST, DASS-21, and other tools were used to assess suicidal behavior with substance use and associated factors. Data were edited, purified, and entered into Epi-data version 4.6 before being exported to the statistical package for social sciences version 20 for analysis of bi-variables to see the associations' p-value < 0.2 and multi-variables to identify the associated variables with a p-value of < 0.05 AOR and CI also done.

RESULTS

From a total of 372 substance user participants over all prevalence of suicidal ideation and attempt among youth was 54(14.5%) with 95% CI of (11.0,18.0) and 37(9.9%) with 95% CI (7.0, 13.0) respectively. Being female [AOR =2.36;95% CI:(1.19, 4.68)], poor social support [AOR =3.03; 95% CI: (1.11, 8.25)], and anxiety [AOR = 3.82: 95% CI; (1.96, 7.46)].

CONCLUSION AND RECOMMENDATIONS

The prevalence of suicidal ideation and attempt among substance users was 14.5 and 9.9% respectively therefore, immediate interventional actions needed to be administered to decrease the burden of suicide by reducing substance use and other associated factors.

Substance Use Frequency Relates to Suicidal Ideation Through Perceived Burdensomeness and to Suicide Attempts Through Capability for Suicide

BACKGROUND

Although substance use has been linked to both suicidal ideation and suicide attempts, the factors underlying these relations remain unclear. The Interpersonal-Psychological Theory of Suicide (ITS) provides a framework for understanding how substance use may increase suicide risk. The purpose of the current study was to examine if frequency of substance use is indirectly related to suicidal ideation and suicide attempts through core ITS variables (i.e., burdensomeness, thwarted belongingness, and suicide capability).

METHODS

An online sample of Mechanical Turk workers (N = 365) completed measures assessing substance use frequency, burdensomeness, thwarted belongingness, suicide capability, suicidal ideation, and suicide attempts.

RESULTS

After controlling for relevant clinical and demographic covariates, substance use frequency was indirectly related to suicidal ideation through burdensomeness but not thwarted belongingness. Substance use frequency was indirectly related to suicide attempts through suicide capability only.

LIMITATIONS

The cross-sectional design precludes conclusions about the precise nature and direction of the relations examined. The use of a community sample limits generalizability to more severe substance using samples.

CONCLUSIONS

Results highlight the relevance of distinct ITS factors in the relation between substance use frequency and both suicidal ideation and suicide attempts. Results may inform specific targets for novel interventions aimed at reducing suicide risk among substance-using individuals.HighlightsSubstance use frequency was indirectly related to SI through burdensomeness.Substance use frequency was not indirectly related to SI through thwarted belongingness.Substance use frequency was indirectly related to SA only through suicide capability.

Prevalence and Correlates of Illicit Substance Use Among Young Adults Experiencing Homelessness in Seven Cities Across the United States

Background

Young adults experiencing homelessness (YAEH) engage in substantially higher substance use rates than housed young adults. This current study builds on previous research by investigating the prevalence of and salient correlates of illicit substance use across a seven-city sample.

Methods

This study used the Homeless Youth Risk and Resiliency Survey (HYRRS) dataset, n=1426 Young adults experiencing homelessness to study patterns and correlates of illicit substance use.

Results

Multivariate logistic regression analyses were used to assess correlates of substance use. Study site, age, gender identity, sexual orientation, history of suicidal ideation, use of specific substances, and trading sex for drugs were associated with five types of illicit substance use (ecstasy, cocaine, crack, methamphetamine, and injection drug use).

Conclusion

Findings indicate that substance use interventions for YAEH must be multifaceted, addressing illicit and multiple substance use, along with the myriad factors associated with substance use among this at-risk group.

Behavioral risk factors for noncommunicable diseases associated with depression and suicide risk in adolescence

Noncommunicable diseases (NCDs) and mental disorders cooccur in adulthood, which is why their determinants and common risk factors should be addressed at an early age. Therefore, we estimated the association of the major risk factors for NCDs with depression and suicide risk by structural equation modeling considering pathways triggered by social vulnerability or mediated by obesity. This population-based study included 2,515 Brazilian adolescents. The following exposures were the major risk factors for NCDs: substance use behaviors (variable deduced from alcohol, tobacco, and drug use), physical inactivity, and components of unhealthy eating markers (added sugar and saturated fat). Obesity was assessed using the fat mass index. The outcomes were depression and suicide risk. Depression was associated with substance use behaviors (SC = 0.304; p < 0.001), added sugar (SC = 0.094; p = 0.005), and females (SC = 0.310; p < 0.001). Suicide risk was also associated with substance use behaviors (SC = 0.356; p < 0.001), added sugar (SC = 0.100; p = 0.012), and females (SC = 0.207; p < 0.001). In adolescents, these associations may help explain the cluster of NCDs and mental disorders in adulthood.

Prevalence and associated factors for suicidal behaviours (ideation, planning, and attempt) among high school adolescents in Lagos, Nigeria

To plan effective school-based adolescent suicide prevention strategies, there is need for valid epidemiology data. The aim of this study was to estimate the current (1 month) prevalence and associated factors of suicidal behaviours (ideation, planning, and attempt) amongst secondary school adolescents in Lagos, Nigeria. A total of 9441 adolescents (4684 males and 4757 females) with mean age 15.61 years (SD 1.49) recruited from 47 public senior secondary schools self-completed questionnaire consisting of sociodemographic, family, school, physical health, and mental health-related variables. Suicidal behaviours (ideation, planning, and attempt) in the past 1 month were also assessed. The weighted 1-month prevalence for suicidal ideation was 6.1% (95% CI 5.5-6.7), suicidal planning was 4.4% (95% CI 3.8-4.9), and suicidal attempt was 2.8% (95% CI 2.4-3.2). The factors significantly associated with suicidal behaviours included being female, not staying with the mother, maternal drinking, witnessing domestic violence, past and present academic difficulties, having no close friend in school and having problems relating with peers and teachers. Also, presence of chronic physical illnesses, depression, anxiety, behavioural disorders, and psychotic-like experiences were associated with adolescent suicidal behaviour. We have shown that a substantial percentage of adolescent have suicidal behaviours, and that there were demographic, family, school, physical health, and psychological health-related factors. We believe that our findings will be important when planning suicide prevention services that could be incorporated into the school mental health services.

The epidemiology of benzodiazepine misuse: A systematic review

BACKGROUND

Benzodiazepine misuse is a growing public health problem, with increases in benzodiazepine-related overdose deaths and emergency room visits in recent years. However, relatively little attention has been paid to this emergent problem. We systematically reviewed epidemiological studies on benzodiazepine misuse to identify key findings, limitations, and future directions for research.

METHODS

PubMed and PsychINFO databases were searched through February 2019 for peer-reviewed publications on benzodiazepine misuse (e.g., use without a prescription; at a higher frequency or dose than prescribed). Eligibility criteria included human studies that focused on the prevalence, trends, correlates, motives, patterns, sources, and consequences of benzodiazepine misuse.

RESULTS

The search identified 1970 publications, and 351 articles were eligible for data extraction and inclusion. In 2017, benzodiazepines and other tranquilizers were the third most commonly misused illicit or prescription drug in the U.S. (approximately 2.2% of the population). Worldwide rates of misuse appear to be similar to those reported in the U.S. Factors associated with misuse include other substance use, receipt of a benzodiazepine prescription, and psychiatric symptoms and disorders. Benzodiazepine misuse encompasses heterogeneous presentations of motives, patterns, and sources. Moreover, misuse is associated with myriad poor outcomes, including mortality, HIV/HCV risk behaviors, poor self-reported quality of life, criminality, and continued substance use during treatment.

CONCLUSIONS

Benzodiazepine misuse is a worldwide public health concern that is associated with a number of concerning consequences. Findings from the present review have implications for identifying subgroups who could benefit from prevention and treatment efforts, critical points for intervention, and treatment targets.

Association between illegal use of substances and suicidal behavior in school students: An integrative review of empirical data

PURPOSE

Investigation of the association between type of suicidal behavior and type and frequency of illegal use of substances (IUS) among school students (aged between 12 and 18 years), with a focus on gender differences.

DESIGN AND METHODS

A systematic review in PubMed, CINAHL, PsychINFO, and Scopus was performed. Identified articles were published between 2007 and 2018.

RESULTS

Twenty empirical studies confirmed the association between IUS and suicidality, strongly differentiated between males and females, highlighting the importance of gender-specific mediating factors.

CONCLUSIONS

Mental health nurses need to document gender factors, frequency, and motivation of IUS when screening adolescents experiencing suicidal behavior and IUS.

Lifestyle Interventions and Prevention of Suicide

Over the past years, there has been a growing interest in the association between lifestyle psychosocial interventions, severe mental illness, and suicide risk. Patients with severe mental disorders have higher mortality rates, poor health states, and higher suicide risk compared to the general population. Lifestyle behaviors are amenable to change through the adoption of specific psychosocial interventions, and several approaches have been promoted. The current article provides a comprehensive review of the literature on lifestyle interventions, mental health, and suicide risk in the general population and in patients with psychiatric disorders. For this purpose, we investigated lifestyle behaviors and lifestyle interventions in three different age groups: adolescents, young adults, and the elderly. Several lifestyle behaviors including cigarette smoking, alcohol use, and sedentary lifestyle are associated with suicide risk in all age groups. In adolescents, growing attention has emerged on the association between suicide risk and internet addiction, cyberbullying and scholastic and family difficulties. In adults, psychiatric symptoms, substance and alcohol abuse, weight, and occupational difficulties seems to have a significant role in suicide risk. Finally, in the elderly, the presence of an organic disease and poor social support are associated with an increased risk of suicide attempt. Several factors may explain the association between lifestyle behaviors and suicide. First, many studies have reported that some lifestyle behaviors and its consequences (sedentary lifestyle, cigarette smoking underweight, obesity) are associated with cardiometabolic risk factors and with poor mental health. Second, several lifestyle behaviors may encourage social isolation, limiting the development of social networks, and remove individuals from social interactions; increasing their risk of mental health problems and suicide.

The SDQ dysregulation profile is associated with self-injurious thoughts and behaviors in adolescents evaluated at a clinical setting

INTRODUCTION

Suicidal ideation, suicidal behavior, and non-suicidal self-injury behavior are serious public health problems among adolescents. A significant proportion of adolescents evaluated in clinical settings meet criteria for the dysregulation profile (DP). DP is characterized by restlessness, irritability, "affective storms", mood instability, and aggression in a disproportionate grade to the situation. This DP might be related to increased risk of self-injurious thoughts and behaviors.

METHODS

Two hundred and thirty-nine adolescents from the Child and Adolescent Outpatient Psychiatric Services of the Jimenez Diaz Foundation, Madrid, were assessed with the Strengths and Difficulties Questionnaire-Dysregulation Profile, the Self-Injurious Thoughts and Behaviors Interview and socio-demographic questionnaires.

RESULTS

Logistic regression showed that DP adolescents were at increased risk for suicide plans, gestures, and suicide attempts. They also tended to present more self-injurious behaviors than adolescents without DP.

CONCLUSIONS

Our results point to the role of self-regulatory problems in the presence of suicide plans, suicide gestures, suicide attempts, and in non-suicidal self-injury behavior. Longitudinal studies are needed to confirm the relationship between the Strengths and Difficulties Questionnaire-Dysregulation Profile and self-injurious thoughts and behaviors.

Epidemiology of adolescent substance use in Norfolk schools

BACKGROUND

The pattern of alcohol and substance use is changing, with the introduction of novel psychoactive substances, the internet as a means of acquisition and variations in drug purity and price. Alcohol and substance use among adolescents is associated with behavioural, mental health, health and social difficulties; arising at a vulnerable period in their development. Little is known about adolescent substance use in the UK, especially in rural areas.

AIM

To investigate the prevalence of substance use amongst young people, aged 16-21 years, in Norfolk schools.

DESIGN

Cross sectional questionnaire survey.

METHOD

Pupils from two, sixth form colleges in Norfolk answered a self-report questionnaire designed to measure prevalence, age of onset and frequency of use for alcohol, tobacco, illicit substances including new psychoactive substances as well as demographic data.

RESULTS

A total of 482 students completed the survey (68% participation rate). Life-time use of alcohol was reported by 442 (91.7%) students and over half the pupils had tried tobacco (52.5%, n=253). About 40.7% reported cannabis use and nearly one-fifth (18.9%, n=91) reported using 3,4-methylenedioxymethamphetamine (MDMA); 41.1% (n=198) students reported using 'any drug' and 23.2% (n=112) 'using an illicit drug other than cannabis' and 8.7% (n=42) reported the use of a novel psychoactive substance.

CONCLUSION

The most widely used substances were alcohol, tobaccos and cannabis; in keeping with European trends. Over the past decade a decline in alcohol and drug use by adolescents has been seen in the UK. However, since 2010 this decline has slowed with an increase in substance use noted in the past 2 years. This study provides evidence to support this trend. The findings demonstrate differences between the use of substances by pupils in this Norfolk sample compared to national surveys and more urbanized areas. These regional differences can be used to assist the development of local interventions targeting substance use among adolescents.

Increasing Knowledge, Skills, and Confidence Concerning Students' Suicidality Through a Gatekeeper Workshop for School Staff

Introduction: Around one-third of adolescents in Germany report a lifetime history of suicide ideation. School staff (e.g., teachers or school social workers) can serve as gatekeepers to identify adolescents at risk and transfer them to appropriate mental health professionals. The aim of this study was to evaluate a gatekeeper training for school staff. Methods: A total of N = 603 school social workers, school psychologists, and teachers participated in one of 33 1.5-day workshops. Knowledge, attitudes, confidence in skills, and perceived knowledge were assessed at pre and post workshops and at 6-month follow-up (FU). Behavioral changes were assessed via self-report at FU. Results: Knowledge, perceived knowledge, and confidence in own skills concerning suicidality increased significantly from pre- to post-assessment and was still significantly increased at 6-month FU. Attitudes toward suicidal adolescents were neutral to positive before the workshop and remained un-changed at FU. Overall, participants were very satisfied with the workshop. Although participants stated to be motivated to make behavioral changes at 6-month FU, they reported obstacles such as lack of resources and support from school administration. Discussion: This 1.5-day gatekeeper workshop was effective in enhancing knowledge and confidence in school staff regarding suicidality. Future workshops would benefit from ongoing supervision and inclusion of school administration in order to facilitate long-term changes on a behavioral level.

The Strengths and Difficulties Questionnaire -Dysregulation Profile, Non-Suicidal Self-Injury Behaviors and the Mediating Role of Stressful Life Events

Non-suicidal self-injury (NSSI) behaviors are self-injurious behaviors inflicted without intending death. Literature has shown the relationship between stressful life events (SLE) and NSSI behaviors. The Strengths and Difficulties Questionnaire-Dysregulation Profile (SDQ-DP) is defined as an index of self-regulatory problems, related to higher risk for suicidal ideation and attempts in adolescents. In this study the relationship between SDQ-DP and NSSI behaviors, mediated by SLE in a clinical sample of children and adolescents is analyzed. A cross-sectional study was conducted on 239 subjects (aged from 11 to 17) to test the mediation model. SDQ-DP significantly correlates with NSSI behaviors (Wald = 6.5477, p = .0105); SDQ-DP significantly correlates with SLE (T = 5.7229, p < .001); SLE significantly correlates NSSI behaviors, and the relation remains significant whilst controlling for SDQ-DP (Wald = 4.1715, p = .041); the relation between SDQ-DP and NSSI behaviors stops being significant whilst controlling for the potential mediator (SLE) (Wald = 2.9951, p = .0835). Study of indirect effect supports the mediation model (.0585 CI [.0016, .1266]). Findings are compatible with the complete mediation scenario. These results point out the importance of self-regulatory problems in coping strategies with regards to SLE and the development of NSSI behaviors.

Adolescent substance use behavior and suicidal behavior for boys and girls: a cross-sectional study by latent analysis approach

BACKGROUND

Adolescent suicidal behavior may consist of different symptoms, including suicidal ideation, suicidal planning and suicidal attempts. Adolescent substance use behavior may contribute to adolescent suicidal behavior. However, research on the relationships between specific substance use and individual suicidal behavior is insufficient, as adolescents may not use only one substance or develop only one facet of suicidal behavior. Latent variables permit us to describe the relationships between clusters of related behaviors more accurately than studying the relationships between specific behaviors. Thus, the aim of this study was to explore how adolescent substance use behavior contributes to suicidal behavior using latent variables representing adolescent suicidal and substance use behaviors.

METHOD

A total of 13,985 adolescents were recruited using a stratified random sampling strategy. The participants indicated whether they had experienced suicidal ideation, planning and attempts and reported their cigarette, alcohol, ketamine and MDMA use during the past year. Latent analysis was used to examine the relationship between substance use and suicidal behavior.

RESULTS

Adolescents who used any one of the above substances exhibited more suicidal behavior. The results of latent variables analysis revealed that adolescent substance use contributed to suicidal behavior and that boys exhibited more severe substance use behavior than girls. However, there was no gender difference in the association between substance use and suicidal behavior.

CONCLUSION

Substance use behavior in adolescents is related to more suicidal behavior. In addition, the contribution of substance use to suicidal behavior does not differ between genders.

Correlation of impulsivity with self-harm and suicidal attempt: a community study of adolescents in Taiwan

OBJECTIVES

The aim of this study was to investigate differences and similarities in risk factors for deliberate self-harm (DSH) and suicidal attempt (SA), and the role of impulsivity among a group of community adolescents.

SETTING

This is a cross-sectional study conducted at high schools in Northern Taiwan.

DATA AND PARTICIPANTS

We recruited grade 1 students from 14 high schools. A total of 5879 participants (mean age 16.02 years, female adolescents: 57.7%) completed the online assessment.

OUTCOME MEASURES

Participants completed online questionnaires about sociodemographic data, suicidality, history of DSH and SA, depressed mood, self-esteem, social support, family discord, impulsivity (Barratt Impulsiveness Scale Version 11 (BIS-11)) and the use of alcohol, tobacco and illicit drugs. A subsample was interviewed about lifetime SA, and the results were compared with those from the online questionnaires.

RESULTS

In our sample, 25% of the students had lifetime DSH and 3.5% had lifetime SA. Two hundred and seventy-two students received face-to-face interviews. The concordance between the online questionnaires and interviews in terms of ascertaining cases of SA was moderate (concordance rate 82.76%; kappa value 0.59). Similar risk factors for DSH/SA among the whole sample included female gender, lower academic performance, depression, substance use (tobacco and alcohol) and low self-esteem. The BIS-11 score was correlated with DSH. Factor 3 score of the BIS-11 (novelty seeking) was correlated with DSH in both boys and girls, whereas factor 2 score (lack of self-control) was correlated with SA in boys. Social support was a protective factor against SA among the female adolescents. Gender modulated the association of impulsivity and DSH/SA. Associations between impulsivity and DSH and SA were particularly strong among boys.

CONCLUSIONS

Risk factors for DSH and SA were similar, but not identical. Early identification of those at risk and appropriate interventions may be helpful.

Polydrug use by European adolescents in the context of other problem behaviours

Aim

Previous studies of the association between polydrug use and other risk behaviours have generally been limited to specific substances and a small number of behaviours. The aim of this study is to obtain better insight into polydrug use (comprising legal and illegal substances: tobacco, alcohol, tranquillisers/sedatives, cannabis, and other illegal drugs) and its association with co-occurring problem behaviours drawn from various broad domains (sexual, aggressive, delinquent, school achievement, relationships) among European adolescents.

Methods

Data were obtained from 101,401 16-year-old students from 35 European countries participating in the 2011 ESPAD survey. Associations between polydrug use and other problem behaviours were examined by multinomial and binary logistic regression analyses.

Results

Tranquillisers/sedatives appeared among the commonest combinations in the polydrug use pattern, especially for females. A strong trend was found between levels of involvement with polydrug use and other problem behaviours for both genders. The highest associations with polydrug use were for problems with the police, risky sexual behaviour and skipping school. Gender differences showed higher prevalences among boys than girls of problem behaviours of aggressive, antisocial type, while girls prevailed over boys in relationship problems.

Conclusion

An incremental relationship exists between the level of involvement with polydrug use and the co-occurrence of problem behaviours. Preventative interventions should consider the misuse of tranquillisers/sedatives within the context of polydrug use by adolescents and expand their target groups towards multiple problem behaviours.

New indicators to compare and evaluate harmful drug use among adolescents in 38 European countries

Aims

New trends in drug consumption reveal increasing polydrug use. Epidemiological indicators in the current use are based on the prevalence and the associated potential harm of a single “main” substance. We propose new indicators to evaluate frequency and potential harm of polydrug use. The indicators are used to compare drug use among countries based on survey data on adolescents' substance use in 38 European countries.

Methods

The approach is based on analysis of the frequency of use in the various population samples: lifetime use, twelve months use or last thirty days, depending on available data, and on the risk of harm for the substances used. Two indicators are provided: the frequency of use score (FUS) by summing the frequency of use of each substance, and the polydrug use score (PDS) that weight all the substances used by their risk.

Results

The indicators FUS and PDS were calculated and the distribution functions were used to characterise substance use across ESPAD countries. The analysis shows important differences in poly-substance use severity among countries presenting similar prevention policies.

Conclusions

Systematic analysis of substance use and the related risk are of paramount interest. The proposed indicators are designed to better monitor and understand consequences of polydrug use and to measure the resulting risk at country or population level. The indicators may also be used to assess the effects of policy interventions.

A new era for drinking? Epidemiological evidence on adolescent male-female differences in drinking incidence in the United States and Europe

PURPOSE

We seek answers to three questions about adolescent risk of starting to drink alcoholic beverages: (1) in new United States (US) data, can we reproduce a recently discovered female excess risk? (2) has a female excess risk emerged in European countries? and (3) might the size of country-level female-male differences (FMD) be influenced by macro-level gender equality and development processes?

METHODS

Estimates are from US and European surveys of adolescents, 2010-2014. For US estimates, newly incident drinking refers to consuming the first full drink during the 12-month interval just prior to assessment. For all countries, lifetime cumulative incidence of drinking refers to any drinking before assessment of the sampled 15-16 years.

RESULTS

Cumulative meta-analysis summary estimates from the US show a highly reproducible female excess in newly incident drinking among 12-17 years (final estimated female-male difference in risk, FMD = 2.1%; 95% confidence interval = 1.5%, 2.7%). Several European countries show female excess risk, estimated as lifetime cumulative incidence of drinking onsets before age 17 years. At the country level, the observed magnitude of FMD in risk is positively associated with the Gender Development Index (especially facets related to education and life expectancy of females relative to males), and with residence in a higher income European country.

CONCLUSIONS

New FMD estimates support reproducibility of a female excess risk in the US. In Europe, evidence of a female excess is modest. Educational attainment, life expectancies, and income merit attention in future FMD research on suspected macro-level processes that influence drinking onsets.

Smoking and Suicide: A Meta-Analysis

BACKGROUND

Many studies have reported a positive association between smoking and suicide, but the results are inconsistent. This meta-analysis was carried out to estimate the association between smoking and suicidal ideation, suicide plan, suicide attempt, and suicide death.

METHODS

Major electronic databases including PubMed, Web of Science, Scopus, and ScienceDirect were searched until May 2015. The reference lists of included studies were screened too. Epidemiological studies addressing the association between smoking and suicidal behaviors were enrolled. The heterogeneity across studies was explored by Q-test and I2 statistic. The possibility of publication bias was assessed using Begg's and Egger's tests and Trim & Fill analysis. The results were reported based on risk ratio (RR) and odds ratio (OR) with 95% confidence intervals (CI) using a random-effects model.

RESULTS

We identified a total of 8062 references and included 63 studies with 8,063,634 participants. Compared to nonsmokers, the current smokers were at higher risk of suicidal ideation (OR = 2.05; 95% CI: 1.53, 2.58; 8 studies; I2 = 80.8%; P<0.001), suicide plan (OR = 2.36; 95% CI: 1.69, 3.02; 6 studies; I2 = 85.2%; P<0.001), suicide attempt (OR = 2.84; 95% CI: 1.49, 4.19; 5 studies; I2 = 89.6%; (P<0.001), and suicide death (RR = 1.83; 95% CI: 1.64, 2.02; 14 studies; I2 = 49.7%; P = 0.018).

CONCLUSIONS

There is sufficient evidence that smoking is associated with an increased risk of suicidal behaviors. Therefore, smoking is a contributing factor for suicide. Although this association does not imply causation, however, smoking prevention and cessation should be the target of suicide prevention programs.

PTSD, Depression, and Substance Use in Relation to Suicidality Risk among Traumatized Minority Lesbian, Gay, and Bisexual Youth

Youths who are lesbian, gay, or bisexual (LGB) are more likely than heterosexuals to commit suicide. Substance use, PTSD, and depression are independent risk factors for suicidality; however, the extent to which these factors interact to predict suicidality is unclear. The current study examined the association between substance use, PTSD symptoms (PTSS), depressive symptoms, and suicidality in a sample of 68 traumatized minority LGB youths. Participants were recruited from an LGBT community center and completed a packet of questionnaires. Substance use and depressive symptoms were positively associated with prior suicide attempts. A significant three-way interaction revealed that substance use interacted with both PTSS and depressive symptoms to increase the odds of attempted suicide. Results underscore the importance of integrating substance use components into PTSD/depression treatment to reduce suicide risk in LGB youth.

Substance use disorder and risk of suicidal ideation, suicide attempt and suicide death: a meta-analysis

BACKGROUND

This meta-analysis addressed the association between substance use disorder (SUD) and suicide outcomes based on current evidence.

METHODS

We searched PubMed, Web of Science and Scopus until May 2015. We also searched the reference lists of included studies and Psycinfo website. We included observational (cohort, case-control, cross-sectional) studies addressing the association between SUD and suicide. Our outcomes of interest were suicide ideation, suicide attempt and suicide death. For each outcome, we calculated the odds ratio (OR) or risk ratio (RR) with 95% confidence intervals (CI) based on the random-effects model.

RESULTS

We identified a total of 12 413 references and included 43 studies with 870 967 participants. There was a significant association between SUD and suicidal ideation: OR 2.04 (95% CI: 1.59, 2.50; I² = 88.8%, 16 studies); suicide attempt OR 2.49 (95% CI: 2.00, 2.98; I² = 94.3%, 24 studies) and suicide death OR 1.49 (95% CI: 0.97, 2.00; I² = 82.7%, 7 studies).

CONCLUSIONS

Based on current evidence, there is a strong association between SUD and suicide outcomes. However, evidence based on long-term prospective cohort studies is limited and needs further investigation. Moreover, further evidence is required to assess and compare the association between suicide outcomes and different types of illicit drugs, dose-response relationship and the way they are used.

Co-occurrence between mental distress and poly-drug use: a ten year prospective study of patients from substance abuse treatment

INTRODUCTION

Longitudinal research investigating psychiatric trajectories among patients with poly-drug use patterns remains relatively scant, even though this specific population is at elevated risk for multiple negative outcomes. The present study examined temporal associations between poly-drug use (i.e. heroin, cannabis, tranquilizers, and amphetamines) and mental distress over a 10-year period.

METHODS

A clinical cohort of 481 patients was recruited from substance use treatment facilities in Norway, and prospectively interviewed 1, 2, 7 and 10years after the initial data collection at treatment admission. At each assessment participants completed a questionnaire addressing their substance use and mental distress. Longitudinal growth models were used to examine whether, and if so, how, levels of drug use were associated with the level and rate of change in mental distress over time.

RESULTS

Results from the longitudinal growth models showed a co-occurrence between active poly-drug use and mental distress, such that there was a dose-response effect where mental distress increased both in magnitude and over time with the number of drugs used. Reduction in mental distress during the 10-year study period was evident only in the no-drug use condition. Use of multiple drugs and mental distress appear strongly co-related over time.

CONCLUSIONS

Pre-treatment assessment should carefully identify individuals manifesting poly-drug use and mental disorders. Treatment and follow-up services should be tailored to their specific needs.

School difficulties and co-occurring health risk factors: substance use, aggression, depression, and suicidal behaviors

PROBLEM

Effective prevention requires understanding vulnerable populations, early signs of health risks, and the impact of social contexts. We tested a model of co-occurring mental health risks among at-risk youth experiencing school difficulties.

METHODS

We analyzed data from a random sample of 336 at-risk youth, grades 9-12, who completed a comprehensive risk/protective factors assessment.

FINDINGS

Simultaneously controlling for correlations among health risks, we observed systematic associations among risk factors, with generally consistent patterns for males and females.

CONCLUSIONS

The findings underscore the importance of developing interventions that incorporate contextual influences and of identifying common adaptable strategies for attenuating co-occurring health risks for at-risk youth.

A cross-sectional study of major repeaters: a distinct phenotype of suicidal behavior

OBJECTIVE

The characterization of major repeaters (individuals with ≥ 5 lifetime suicide attempts) is a neglected area of research. Our aim was to establish whether or not major repeaters are a distinctive suicidal phenotype, taking into account a wide range of potential competing risks including sociodemographic characteristics, personal and familial history, psychiatric diagnoses, and personality traits.

METHOD

This cross-sectional study included 372 suicide attempters admitted to a specialized unit for suicide attempters in Montpellier University Hospital, Montpellier, France, between October 12, 2000, and June 10, 2010. Logistic regression models controlling for potential confounders were used.

RESULTS

When compared with subjects who attempted suicide < 5 times, major repeaters were more likely to be female (odds ratio [OR] = 5.54; 95% CI, 1.41-21.81), to have a lower educational level (OR = 5.1; 95% CI, 1.55-17.2), to have lifetime diagnoses of anorexia nervosa (OR = 3.45; 95% CI, 1.10-10.84) and substance dependence (OR = 5.00; 95% CI, 1.37-18.27), and to have lower levels of anger expressed outward (OR = 0.17; 95% CI, 0.06-0.47) and higher levels of trait anger (OR = 2.82; 95% CI, 1.18-6.75). Major repeaters had significantly higher suicide risk (lethality) scores (OR = 2.14; 95% CI, 1.08-4.23).

CONCLUSION

Major repeaters are a distinctive suicidal phenotype characterized by a distinctive sociodemographic (ie, female gender, low education) and clinical profile (ie, trait anger, substance dependence, anorexia nervosa). If our results are replicated, specific preventive plans should be tailored to major repeaters.

Adolescent alcohol use and alcohol use disorders in Mexico City

OBJECTIVE

To estimate the prevalence, sex, age distribution, and socio-demographic correlates of any alcohol use, consumption patterns, and any alcohol use disorder in a representative sample of Mexican adolescents.

METHODS

3005 youth (52.1% female) aged 12-17 from a stratified multistage area probability sample were representative of adolescents residing in the Mexico City Metropolitan Area. Alcohol use and disorder and their socio-demographic correlates were evaluated with the World Mental Health adolescent version of the Composite International Diagnostic Interview. Data were post-stratified to the total Mexico City adolescent population.

RESULTS

59% has used alcohol, this proportion increasing significantly with age. By age 17, 82.5% has used alcohol. Consumption patterns are mostly of low/moderate quantity or infrequent high quantity. Lifetime DSM-IV alcohol use disorder criteria are met by 3.8%, reaching 8.1% for 16-17 years-olds. While males have greater frequency and quantity of drinking, there are no gender differences for alcohol use disorders. Non-school attending youth have twice the odds of a lifetime (OR=2.0, 95% CI=1.13-3.53) and 12-month disorder (OR=2.1, 95% CI=1.10-4.15). Low parental monitoring is associated with 1.72 times the odds of a lifetime disorder (95% CI=1.10-2.68).

CONCLUSIONS

Over a third of 12 year-olds had ever drunk an alcoholic beverage in their lifetime suggesting that the prevention of alcohol use and disorders must begin in late childhood. Initiatives to foment parental monitoring and to prevent, identify, and treat alcohol use problems in non-school attending youth in particular should be a priority for the wellbeing of Mexico City adolescents.

Hospitalizations for suicide-related drug poisonings and co-occurring alcohol overdoses in adolescents (ages 12-17) and young adults (ages 18-24) in the United States, 1999-2008: results from the Nationwide Inpatient Sample

Drug poisoning is the leading method of suicide-related deaths among females and third among males in the United States. Alcohol can increase the severity of drug poisonings, yet the prevalence of alcohol overdoses in suicide-related drug poisonings (SRDP) remains unclear. Data from the Nationwide Inpatient Sample was examined to determine rates of inpatient hospital stays for SRDP and co-occurring alcohol overdoses in adolescents (ages 12-17) and young adults (ages 18-24) between 1999 and 2008. Among adolescents, there were 14,615 hospitalizations for drug poisonings in 2008, of which 72% (10,462) were suicide-related at a cost of $43 million. Rates of SRDP in this age group decreased between 1999 and 2008. The prevalence of co-occurring alcohol overdoses increased from 5% in 1999 to 7% in 2008. Among young adults, there were 32,471 hospitalizations for drug poisonings in 2008, of which 64% (20,746) were suicide-related at a cost of $110 million. Rates of SRDP did not change significantly between 1999 and 2008. The prevalence of co-occurring alcohol overdoses increased from 14% in 1999 to 20% in 2008. Thus, while rates of SRDP decreased for adolescents and remained unchanged for young adults, the prevalence of co-occurring alcohol overdoses increased for both age groups. Such hospitalizations provide important opportunities to employ intervention techniques to prevent further suicide attempts.
