    ABSTRACT: To screen and clinically interview European adolescents reporting current suicidality (suicidal ideation and suicide attempt) and investigate attendance at the clinical interview. The Saving and Empowering Young Lives in Europe (SEYLE) Project was carried out in 11 European countries. A baseline questionnaire was completed in school by 12,395 adolescents (mean age 14.9; SD 0.9). Those who screened positive for suicidality (attempting suicide and/or serious suicidal ideation or plans) in the past 2 weeks were invited to a clinical interview with a mental health professional. Of the 12,395 adolescents, 4.2 % (n = 516) screened positive for current suicidality. The prevalence ranged from 1.1 % in Hungary to 7.7 % in Israel (p < 0.001). 37.6 % (n = 194) of those who screened positive subsequently attended the clinical interview. Female students were more likely to attend for interview (42.0 % versus 30.6 %, p = 0.010). The attendance rate varied considerably across countries, from 5.7 % in Italy to 96.7 % in France (p < 0.001). Improved attendance was associated with using school as the only interview setting (Mean attendance rate, MAR = 88 vs. 31 %, p = 0.006) and arranging the interview within 1 week of contacting the student (MAR = 64 vs. 23 %, p = 0.013). The greater the travel time to interview, the lower the attendance rate (Pearson's r = -0.64, p = 0.034). Independent of the variation by country, at the individual level, adolescents with more depressive symptoms and a recent suicide attempt more often attended for interview. A high rate of current suicidality was found amongst European adolescents. However, the majority of these displayed limited help-seeking behaviour. Future studies should investigate ways of making screening programmes and other interventions more acceptable and accessible to young people, especially young males.

    ABSTRACT: Background Suicidal behaviours in adolescents are a major public health problem and evidence-based prevention programmes are greatly needed. We aimed to investigate the efficacy of school-based preventive interventions of suicidal behaviours. Methods The Saving and Empowering Young Lives in Europe (SEYLE) study is a multicentre, cluster-randomised controlled trial. The SEYLE sample consisted of 11 110 adolescent pupils, median age 15 years (IQR 14–15), recruited from 168 schools in ten European Union countries. We randomly assigned the schools to one of three interventions or a control group. The interventions were: (1) Question, Persuade, and Refer (QPR), a gatekeeper training module targeting teachers and other school personnel, (2) the Youth Aware of Mental Health Programme (YAM) targeting pupils, and (3) screening by professionals (ProfScreen) with referral of at-risk pupils. Each school was randomly assigned by random number generator to participate in one intervention (or control) group only and was unaware of the interventions undertaken in the other three trial groups. The primary outcome measure was the number of suicide attempt(s) made by 3 month and 12 month follow-up. Analysis included all pupils with data available at each timepoint, excluding those who had ever attempted suicide or who had shown severe suicidal ideation during the 2 weeks before baseline. This study is registered with the German Clinical Trials Registry, number DRKS00000214. Findings Between Nov 1, 2009, and Dec 14, 2010, 168 schools (11 110 pupils) were randomly assigned to interventions (40 schools [2692 pupils] to QPR, 45 [2721] YAM, 43 [2764] ProfScreen, and 40 [2933] control). No significant differences between intervention groups and the control group were recorded at the 3 month follow-up. At the 12 month follow-up, YAM was associated with a significant reduction of incident suicide attempts (odds ratios [OR] 0·45, 95% CI 0·24–0·85; p=0·014) and severe suicidal ideation (0·50, 0·27–0·92; p=0·025), compared with the control group. 14 pupils (0·70%) reported incident suicide attempts at the 12 month follow-up in the YAM versus 34 (1·51%) in the control group, and 15 pupils (0·75%) reported incident severe suicidal ideation in the YAM group versus 31 (1·37%) in the control group. No participants completed suicide during the study period. Interpretation YAM was effective in reducing the number of suicide attempts and severe suicidal ideation in school-based adolescents. These findings underline the benefit of this universal suicide preventive intervention in schools. Funding Coordination Theme 1 (Health) of the European Union Seventh Framework Programme.

    ABSTRACT: There is expedient evidence showing that differences in adolescent alcohol consumption and other risk-behaviour depend on both family structure and family member drunkenness exposure. Data were obtained among adolescents (N = 12,115, mean age 14.9 ± 0.89) in Austria, Estonia, France, Germany, Hungary, Ireland, Israel, Italy, Romania, Slovenia and Spain within the European Union's 7th Framework Programme funded project, 'Saving and Empowering Young Lives in Europe (SEYLE)'. The current study reveals how adolescents' alcohol consumption patterns are related to their family structure and having seen their family member drunk. The results revealed statistically significant differences in adolescent alcohol consumption depending on whether the adolescent lives in a family with both birth parents, in a single-parent family or in a family with one birth parent and one step-parent. The study also revealed that the abstaining from alcohol percentage among adolescents was greater in families with both birth parents compared to other family types. The study also showed that the more often adolescents see their family member drunk the more they drink themselves. There is no difference in adolescent drinking patterns whether they see their family member drunk once a month or once a week. This study gives an insight on which subgroups of adolescents are at heightened risk of alcohol abuse and that decrease of family member drunkenness may have positive effects on the drinking habits of their children.

    ABSTRACT: This study examined victimisation, substance misuse, relationships, sexual activity, mental health difficulties and suicidal behaviour among adolescents with sexual orientation concerns in comparison to those without such concerns. 1112 Irish students (mean age 14 yrs) in 17 mixed-gender secondary schools completed a self-report questionnaire with standardised scales and measures of psychosocial difficulties. 58 students (5%) reported having concerns regarding their sexual orientation. Compared with their peers, they had higher levels of mental health difficulties and a markedly-increased prevalence of attempted suicide (29% vs. 2%), physical assault (40% vs. 8%), sexual assault (16%vs. 1%) and substance misuse. Almost all those (90%) with sexual orientation concerns reported having had sex compared to just 4% of their peers. These results highlight the significant difficulties associated with sexual orientation concerns in adolescents in Ireland. Early and targeted interventions are essential to address their needs.

    ABSTRACT: Rising global rates of pathological Internet use (PIU) and related psychological impairments have gained considerable attention in recent years. In an effort to acquire evidence-based knowledge of this relationship, the main objective of this study was to investigate the association between PIU, psychopathology and self-destructive behaviours among school-based adolescents in eleven European countries. This cross-sectional study was implemented within the framework of the European Union project: Saving and Empowering Young Lives in Europe. A representative sample of 11,356 school-based adolescents (M/F: 4,856/6,500; mean age: 14.9) was included in the analyses. PIU was assessed using the Young's Diagnostic Questionnaire. Psychopathology was measured using the Beck Depression Inventory-II, Zung Self-Rating Anxiety Scale and Strengths and Difficulties Questionnaire. Self-destructive behaviours were evaluated by the Deliberate Self-Harm Inventory and Paykel Suicide Scale. Results showed that suicidal behaviours (suicidal ideation and suicide attempts), depression, anxiety, conduct problems and hyperactivity/inattention were significant and independent predictors of PIU. The correlation between PIU, conduct problems and hyperactivity/inattention was stronger among females, while the link between PIU and symptoms of depression, anxiety and peer relationship problems was stronger among males. The association between PIU, psychopathology and self-destructive behaviours was stronger in countries with a higher prevalence of PIU and suicide rates. These findings ascertain that psychopathology and suicidal behaviours are strongly related to PIU. This association is significantly influenced by gender and country suggesting socio-cultural influences. At the clinical and public health levels, targeting PIU among adolescents in the early stages could potentially lead to improvements of psychological well-being and a reduction of suicidal behaviours.

    ABSTRACT: OBJECTIVE The authors describe use of mental health services among children and adolescents after the September 11, 2001, attack on the World Trade Center. METHODS Six months after the attack, sixth- through 12th-graders (N=6,986) who were representative of the student population were asked about their use of mental health services to talk about the attack as well as their exposure to the attack, symptoms of posttraumatic stress and major depressive disorders, and any conversations about the attack with a parent, teacher, or religious leader. RESULTS Eighteen percent had used mental health services. Using in-school services was associated with conversation with a teacher about the attack. Using services outside school was associated with direct exposure to the attack, previous trauma exposure, probable psychiatric diagnosis, and conversation with a teacher or religious leader about the attack. CONCLUSIONS Teachers and religious leaders can function as gatekeepers to identify children in need following a disaster.

    ABSTRACT: This study explored the prevalence of risk behaviors (excessive alcohol use, illegal drug use, heavy smoking, reduced sleep, overweight, underweight, sedentary behavior, high use of Internet/TV/videogames for reasons not related to school or work, and truancy), and their association with psychopathology and self-destructive behaviors, in a sample of 12,395 adolescents recruited in randomly selected schools across 11 European countries. Latent class analysis identified three groups of adolescents: a low-risk group (57.8%) including pupils with low or very low frequency of risk behaviors; a high-risk group (13.2%) including pupils who scored high on all risk behaviors, and a third group ("invisible" risk, 29%) including pupils who were positive for high use of Internet/TV/videogames for reasons not related to school or work, sedentary behavior and reduced sleep. Pupils in the "invisible" risk group, compared with the high-risk group, had a similar prevalence of suicidal thoughts (42.2% vs. 44%), anxiety (8% vs. 9.2%), subthreshold depression (33.2% vs. 34%) and depression (13.4% vs. 14.7%). The prevalence of suicide attempts was 5.9% in the "invisible" group, 10.1% in the high-risk group and 1.7% in the low-risk group. The prevalence of all risk behaviors increased with age and most of them were significantly more frequent among boys. Girls were significantly more likely to experience internalizing (emotional) psychiatric symptoms. The "invisible" group may represent an important new intervention target group for potentially reducing psychopathology and other untoward outcomes in adolescence, including suicidal behavior.

    ABSTRACT: Objectives Anxiety and concerns in daily life may result in sleep problems and consistent evidence suggests that inadequate sleep has several negative consequences on cognitive performance, physical activity, and health. The aim of our study was to evaluate the association between mean hours of sleep per night, psychologic distress, and behavioral concerns. Methods A cross-sectional analysis of the correlation between the number of hours of sleep per night and the Zung Self-rating Anxiety Scale (Z-SAS), the Paykel suicidal Scale (PSS), and the Strengths and Difficulties Questionnaire (SDQ), was performed on 11,788 pupils (mean age±standard deviation [SD], 14.9±0.9; 55.8% girls) from 11 different European countries enrolled in the SEYLE (Saving and Empowering Young Lives in Europe) project. Results The mean number of reported hours of sleep per night during school days was 7.7 (SD, ±1.3), with moderate differences across countries (r=0.06; P<.001). A reduced number of sleeping hours (less than the average) was more common in girls (β=0.10 controlling for age) and older pupils (β=0.10 controlling for sex). Reduced sleep was found to be associated with increased scores on SDQ subscales of emotional (β=−0.13) and peer-related problems (β=−0.06), conduct (β=−0.07), total SDQ score (β=−0.07), anxiety (Z-SAS scores, β=−10), and suicidal ideation (PSS, β=−0.16). In a multivariate model including all significant variables, older age, emotional and peer-related problems, and suicidal ideation were the variables most strongly associated with reduced sleep hours, though female gender, conduct problems measured by the SDQ, and anxiety only showed modest effects (β=0.03–0.04). Conclusions Our study supports evidence that reduced hours of sleep are associated with potentially severe mental health problems in adolescents. Because sleep problems are common among adolescents partly due to maturational processes and changes in sleep patterns, parents, other adults, and adolescents should pay more attention to their sleep patterns and implement interventions, if needed.

    ABSTRACT: The field of medical geographic information systems (Medical GIS) has become extremely useful in understanding the bigger picture of public health. The discipline holds a substantial capacity to understand not only differences, but also similarities in population health all over the world. The main goal of marrying the disciplines of medical geography, public health and informatics is to understand how countless health issues impact populations, and the trends by which these populations are affected. From the 1990s to today, this practical approach has become a valued and progressive system in analyzing medical and epidemiological phenomena ranging from cholera to cancer. The instruments supporting this field include geographic information systems (GIS), disease surveillance, big data, and analytical approaches like the Geographical Analysis Machine (GAM), Dynamic Continuous Area Space Time Analysis (DYCAST), cellular automata, agent-based modeling, spatial statistics and self-organizing maps. The positive effects on disease mapping have proven to be tremendous as these instruments continue to have a great impact on the mission to improve worldwide health care. While traditional uses of GIS in public health are static and lacking real-time components, implementing a space-time animation in these instruments will be monumental as technology and data continue to grow.

    ABSTRACT: Indicated prevention of mental illness is an important public health concern among youth. The aim of this study was to establish a European school-based professional screening among adolescents, which included variables on both a broad range of risk-behaviours and psychopathology; and to investigate the indicative value of adolescent risk-behaviour and self-reported psychopathology on help-seeking and psychological problems that required subsequent mental healthcare. A two-stage professional screening approach was developed and performed within the multi-centre study "Saving and Empowering Young Lives in Europe" (SEYLE). The first stage of screening comprised a self-report questionnaire on a representative sample of 3,070 adolescents from 11 European countries. In the second stage, students deemed at-risk for mental health problems were evaluated using a semi-structured clinical interview performed by healthcare professionals. 61 % of participants (n = 1,865) were identified as being at-risk in stage one. In stage two, 384 participants (12.5 % of the original sample) were found to require subsequent mental healthcare during semi-structured, clinical assessment. Among those, 18.5 % of pupils were identified due to screening for psychopathology alone; 29.4 % due to screening for risk-behaviours alone; and 52.1 % by a combination of both. Young age and peer victimization increased help-seeking, while very low body mass index, depression, suicidal behaviour and substance abuse were the best predictors of referral to mental healthcare. Screening of risk-behaviours significantly increased the number of detected students requiring subsequent mental healthcare. Screening of risk-behaviours added significant value in identifying the significant amount of European pupils with mental health problems. Therefore, attention to adolescent risk-behaviours in addition to psychopathology is critical in facilitating prevention and early intervention. Identifying factors that increase compliance to clinical interviews are crucial in improving screening procedures.

    ABSTRACT: To investigate the prevalence and associated psychosocial factors of occasional and repetitive direct self-injurious behavior (D-SIB), such as self-cutting, -burning, -biting, -hitting, and skin damage by other methods, in representative adolescent samples from 11 European countries. Cross-sectional assessment of adolescents was performed within the European Union funded project, Saving and Empowering Young Lives in Europe (SEYLE), which was conducted in 11 European countries. The representative sample comprised 12,068 adolescents (F/M: 6,717/5,351; mean age: 14.9 ± 0.89) recruited from randomly selected schools. Frequency of D-SIB was assessed by a modified 6-item questionnaire based on previously used versions of the Deliberate Self-Harm Inventory (DSHI). In addition, a broad range of demographic, social, and psychological factors was assessed. Overall lifetime prevalence of D-SIB was 27.6%; 19.7% reported occasional D-SIB and 7.8% repetitive D-SIB. Lifetime prevalence ranged from 17.1% to 38.6% across countries. Estonia, France, Germany, and Israel had the highest lifetime rates of D-SIB, while students from Hungary, Ireland, and Italy reported low rates. Suicidality as well as anxiety and depressive symptoms had the highest odds ratios for both occasional and repetitive D-SIB. There was a strong association of D-SIB with both psychopathology and risk-behaviors, including family related neglect and peer-related rejection/victimization. Associations between psychosocial variables and D-SIB were strongly influenced by both gender and country. Only a minor proportion of the adolescents who reported D-SIB ever received medical treatment. These results suggest high lifetime prevalence of D-SIB in European adolescents. Prevalence as well as psychosocial correlates seems to be significantly influenced by both gender and country. These results support the need for a multidimensional approach to better understand the development of SIB and facilitate culturally adapted prevention/intervention.

    ABSTRACT: IMPORTANCE Up to 1 million persons die by suicide annually. However, a lack of risk markers makes suicide risk assessment one of the most difficult areas of clinical practice. OBJECTIVE To assess psychotic symptoms (attenuated or frank) as a clinical marker of risk for suicide attempt. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort study of 1112 school-based adolescents (aged 13-16 years), assessed at baseline and at 3 and 12 months for self-reported psychopathology, psychotic symptoms, and suicide attempts. MAIN OUTCOMES AND MEASURES Suicide attempts at the 3- and 12-month follow-up and acute suicide attempts (defined as those occurring in the 2 weeks before an assessment). RESULTS Of the total sample, 7% reported psychotic symptoms at baseline. Of that subsample, 7% reported a suicide attempt by the 3-month follow-up compared with 1% of the rest of the sample (odds ratio [OR], 10.01; 95% CI, 2.24-45.49), and 20% reported a suicide attempt by the 12-month follow-up compared with 2.5% of the rest of the sample (OR, 11.27; 95% CI, 4.44-28.62). Among adolescents with baseline psychopathology who reported psychotic symptoms, 14% reported a suicide attempt by 3 months (OR, 17.91; 95% CI, 3.61-88.82) and 34% reported a suicide attempt by 12 months (OR, 32.67; 95% CI, 10.42-102.41). Adolescents with psychopathology who reported psychotic symptoms had a nearly 70-fold increased odds of acute suicide attempts (OR, 67.50; 95% CI, 11.41-399.21). Differences were not explained by nonpsychotic psychiatric symptom burden, multimorbidity, or substance use. In a causative model, the population-attributable fraction of suicide attempts would be 56% to 75% for psychotic symptoms. CONCLUSIONS AND RELEVANCE Adolescents with psychopathology who report psychotic symptoms are at clinical high risk for suicide attempts. More careful clinical assessment of psychotic symptoms (attenuated or frank) in mental health services and better understanding of their pathological significance are urgently needed.

    ABSTRACT: BACKGROUND: Mental health problems and risk behaviours among young people are of great public health concern. Consequently, within the VII Framework Programme, the European Commission funded the Saving and Empowering Young Lives in Europe (SEYLE) project. This Randomized Controlled Trial (RCT) was conducted in eleven European countries, with Sweden as the coordinating centre, and was designed to identify an effective way to promote mental health and reduce suicidality and risk taking behaviours among adolescents. OBJECTIVE: To describe the methodological and field procedures in the SEYLE RCT among adolescents, as well as to present the main characteristics of the recruited sample. METHODS: Analyses were conducted to determine: 1) representativeness of study sites compared to respective national data; 2) response rate of schools and pupils, drop-out rates from baseline to 3 and 12 month follow-up, 3) comparability of samples among the four Intervention Arms; 4) properties of the standard scales employed: Beck Depression Inventory, Second Edition (BDI-II), Zung Self-Rating Anxiety Scale (Z-SAS),Strengths and Difficulties Questionnaire (SDQ), World Health Organization Well-Being Scale (WHO-5), Deliberate Self-Harm Inventory (DSHI) and Paykel Suicide Scale (PSS). RESULTS: Participants at baseline comprised 12,395 adolescents (M/F: 5,529/6,799; mean age=14.9+/-0.9) from Austria, Estonia, France, Germany, Hungary, Ireland, Israel, Italy, Romania, Slovenia and Spain. At the 3 and 12 months follow up, participation rates were 87.3% and 79.4%, respectively. Demographic characteristics of participating sites were found to be reasonably representative of their respective national population. Overall response rate of schools was 67.8%. All scales utilised in the study had good to very good internal reliability, as measured by Cronbach's alpha (BDI-II: 0.864; Z-SAS: 0.805; SDQ: 0.740; WHO-5: 0.799). CONCLUSIONS: SEYLE achieved its objective of recruiting a large representative sample of adolescents within participating European countries. Analysis of SEYLE data will shed light on the effectiveness of important interventions aimed at improving adolescent mental health and well-being, reducing risk-taking and self-destructive behaviour and preventing suicidality.Trial registration: US National Institute of Health (NIH) clinical trial registry (NCT00906620) and the German Clinical Trials Register (DRKS00000214).

    ABSTRACT: OBJECTIVE Using longitudinal and prospective measures, the authors assessed the relationship between childhood trauma and psychotic experiences, addressing the following questions: 1) Does exposure to trauma predict incident psychotic experiences? 2) Does cessation of trauma predict cessation of psychotic experiences? 3) What is the direction of the relationship between childhood trauma and psychotic experiences? METHOD This was a nationally representative prospective cohort study of 1,112 school-based adolescents 13-16 years of age, assessed at baseline and at 3-month and 12-month follow-ups for childhood trauma (physical assault and bullying) and psychotic experiences. RESULTS A bidirectional relationship was observed between childhood trauma and psychosis, with trauma predicting psychotic experiences over time and vice versa. However, even after accounting for this bidirectional relationship with a number of strict adjustments (only newly incident psychotic experiences occurring over the course of the study following exposure to traumatic experiences were examined), trauma was strongly predictive of psychotic experiences. A dose-response relationship was observed between severity of bullying and risk for psychotic experiences. Moreover, cessation of trauma predicted cessation of psychotic experiences, with the incidence of psychotic experiences decreasing significantly in individuals whose exposure to trauma ceased over the course of the study. CONCLUSIONS After a series of conservative adjustments, the authors found that exposure to childhood trauma predicted newly incident psychotic experiences. The study also provides the first direct evidence that cessation of traumatic experiences leads to a reduced incidence of psychotic experiences.

    ABSTRACT: Background:  Subthreshold-depression and anxiety have been associated with significant impairments in adults. This study investigates the characteristics of adolescent subthreshold-depression and anxiety with a focus on suicidality, using both categorical and dimensional diagnostic models. Methods:  Data were drawn from the Saving and Empowering Young Lives in Europe (SEYLE) study, comprising 12,395 adolescents from 11 countries. Based on self-report, including Beck Depression Inventory-II (BDI-II), Zung Self-Rating Anxiety Scale (SAS), Strengths and Difficulties Questionnaire (SDQ) and Paykel Suicide Scale (PSS) were administered to students. Based on BDI-II, adolescents were divided into three groups: nondepressed, subthreshold-depressed and depressed; based on the SAS, they were divided into nonanxiety, subthreshold-anxiety and anxiety groups. Analyses of Covariance were conducted on SDQ scores to explore psychopathology of the defined groups. Logistic regression analyses were conducted to explore the relationships between functional impairments, suicidality and subthreshold and full syndromes. Results:  Thirty-two percent of the adolescents were subthreshold-anxious and 5.8% anxious, 29.2% subthreshold-depressed and 10.5% depressed, with high comorbidity. Mean scores of SDQ of subthreshold-depressed/anxious were significantly higher than the mean scores of the nondepressed/nonanxious groups and significantly lower than those of the depressed/anxious groups. Both subthreshold and threshold-anxiety and depression were related to functional impairment and suicidality. Conclusions:  Subthreshold-depression and subthreshold-anxiety are associated with an increased burden of disease and suicide risk. These results highlight the importance of early identification of adolescent subthreshold-depression and anxiety to minimize suicide. Incorporating these subthreshold disorders into a diagnosis could provide a bridge between categorical and dimensional diagnostic models.
