Suicidal behaviours in vulnerable adolescents. Time trends and their correlates

Potential lethality of suicide attempts in youth

Rates of suicide in youth have increased over the last 50 years, yet our ability to predict suicidal behaviours has not significantly improved during this time. Examining predictors of suicide attempt lethality can enhance our understanding of suicidality in youth, yet research has focused on actual medical lethality (the actual danger to life resulting from a suicide attempt) rather than potential lethality (the potential for death that is associated with a suicide attempt). Thus, the aim of the present study was twofold: first, we quantified the percentage of youth for whom the severity of suicide attempt was misclassified by considering only actual lethality; second, we tested whether key variables that predict the actual lethality of suicide attempts also predict the potential lethality of suicide attempts in youth. We examined these questions in a sample of children and adolescents admitted to a psychiatric inpatient unit following a suicide attempt. Over 70% of youth who made serious suicide attempts would have been misclassified by assessments relying on only actual lethality. Although several variables relevant to the construct of actual lethality significantly predicted potential lethality (e.g., male sex, substance use disorder), others did not. In addition, we found that the subset of youth who would have been misclassified as low risk based on actual lethality had a disproportionately high need for healthcare resources due to future hospital admissions. The present study provides evidence to suggest that considering potential lethality may lead to improved detection and prediction of suicide risk in youth, and in doing so supports recent calls to broaden considerations of the lethality associated with suicide attempts.

Using New and Emerging Technologies to Identify and Respond to Suicidality Among Help-Seeking Young People: A Cross-Sectional Study

BACKGROUND

Suicidal thoughts are common among young people presenting to face-to-face and online mental health services. The early detection and rapid response to these suicidal thoughts and other suicidal behaviors is a priority for suicide prevention and early intervention efforts internationally. Establishing how best to use new and emerging technologies to facilitate person-centered systematic assessment and early intervention for suicidality is crucial to these efforts.

OBJECTIVE

The aim of this study was to examine the use of a suicidality escalation protocol to respond to suicidality among help-seeking young people.

METHODS

A total of 232 young people in the age range of 16-25 years were recruited from either a primary mental health care service or online in the community. Each young person used the Synergy Online System and completed an initial clinical assessment online before their face-to-face or online clinical appointment. A suicidality escalation protocol was used to identify and respond to current and previous suicidal thoughts and behaviors.

RESULTS

A total of 153 young people (66%, 153/232) reported some degree of suicidality and were provided with a real-time alert online. Further levels of escalation (email or phone contact and clinical review) were initiated for the 35 young people (15%, 35/232) reporting high suicidality. Higher levels of psychological distress (P<.001) and a current alcohol or substance use problem (P=.02) predicted any level of suicidality compared with no suicidality. Furthermore, predictors of high suicidality compared with low suicidality were higher levels of psychological distress (P=.01), psychosis-like symptoms in the last 12 months (P=.01), a previous mental health problem (P=.01), and a history of suicide planning or attempts (P=.001).

CONCLUSIONS

This study demonstrates the use of new and emerging technologies to facilitate the systematic assessment and detection of help-seeking young people presenting with suicidality. This protocol empowered the young person by suggesting pathways to care that were based on their current needs. The protocol also enabled an appropriate and timely response from service providers for young people reporting high suicidality that was associated with additional comorbid issues, including psychosis-like symptoms, and a history of suicide plans and attempts.

Suicide ideation, psychological adjustment and mental health service support: A screening study in an Irish secondary school sample

Objective: The aim of this exploratory study was to investigate the extent of suicide ideation, psychological maladjustment and views of mental health service support in a sample of secondary school pupils.

Method: A cross-sectional survey was conducted on a purposive sample of participants (n=93) recruited from a secondary school located in the south east of Ireland. Participants completed a Background Information Questionnaire (BIQ); the Suicide Ideation Questionnaire (SIQ); and the Reynolds Adolescence Adjustment Screening Inventory (RAASI).

Results: Approximately ten percent of participants displayed high levels of suicide ideation whilst one third reported having previously had suicidal thoughts; one quarter reported psychological adjustment difficulties, although these varied by age and sex. Participants' drug use and their levels of parental closeness were both individual factors that significantly predicted both suicide ideation and psychological adjustment. Females reported higher levels of parental closeness than males. Forty percent of respondents rated mental health support services as insufficient to meet their needs.

Conclusion: The findings raise serious concerns about the extent of suicidal thoughts amongst young people in Ireland; they also highlight a potentially important role for parents in this regard. Further research should ascertain national prevalence rates whilst appropriate school-based mental health education/promotion and support services should also be implemented.

Persistence of psychological problems in adolescence: a one year follow-up study

Objectives: To examine the prevalence and persistence of psychological problems in older adolescents.

Methods: This study is a one year follow-up of 110 adolescents, 64 girls and 46 boys attending three secondary schools in Ireland. All were 16 at initial testing. The Youth Self Report (YSR) was the measure used.

Results: Over a fifth of adolescents have problems in the clinical range. These problems persisted from 16 to 17. Females reported more problems than males at both ages. Some females showed a slight reduction in internalising problems at 17. Both males and females showed an increase in externalising problems at 17. Odds ratios indicate that those in the clinical ranges of the YSR at 16, had increased risk of being in the clinical range at 17 compared to those in the no problem range at 16. In comparison to those with no suicidal feeling, those with suicidal feelings at 16 were at an increased risk of still feeling suicidal at 17. More males remained psychologically healthy than girls.

Conclusions: A large proportion of adolescents in this sample have psychological problems and these appear to persist over a one year period. These problems impact substantially on the adolescents themselves, their families and society. Given the increasing suicide rate in young people and the persistence of suicidal feelings in this cohort, the inadequacy of mental health services in Ireland for adolescents, particularly those ages 16-18 is highlighted. The challenge of developing and providing adolescent friendly services is addressed.

Mediating effects of bullying involvement on the relationship of body mass index with social phobia, depression, suicidality, and self-esteem and sex differences in adolescents in Taiwan

The aims of this study were to examine the mediating effect of bullying involvement on the relationships between body mass index (BMI) and mental health problems, including social phobia, depression, suicidality, and low self-esteem among adolescents in Taiwan. The moderation effect of sex on the mediating role of bullying involvement was also examined. Five thousand two hundred and fifty-two students of high schools completed the questionnaires. Victimization and perpetration of passive and active bullying were assessed using the Chinese version of the School Bullying Experience Questionnaire. BMI was calculated from self-reported weight and height measurements. The Social Phobia Inventory, the Mandarin Chinese version of the Center for Epidemiological Studies-Depression Scale, the suicidality-related questionnaire from the epidemiological version of the Kiddie-Schedule for Affective Disorders and Schizophrenia, and the Rosenberg Self-Esteem Scale were applied to assess social phobia, depression, suicidality, and low self-esteem, respectively. The mediating effect of bullying involvement on the associations between increased BMI and mental health problems was examined by the Sobel test. The moderation effect of sex on the mediating role of bullying involvement was tested by the multiple-group structural equation model. Victimization of passive and active bullying and perpetration of passive bullying, but not perpetration of active bullying, had a mediating effect on the relationships between increased BMI and all four mental health problems. Sex did not have a significant moderation effect on the mediating role of bullying involvement. Bullying involvement should be a target of prevention and intervention in developing a strategy to improve mental health among adolescents with increased BMI.

Cyber bullying and physical bullying in adolescent suicide: the role of violent behavior and substance use

The impact of bullying in all forms on the mental health and safety of adolescents is of particular interest, especially in the wake of new methods of bullying that victimize youths through technology. The current study examined the relationship between victimization from both physical and cyber bullying and adolescent suicidal behavior. Violent behavior, substance use, and unsafe sexual behavior were tested as mediators between two forms of bullying, cyber and physical, and suicidal behavior. Data were taken from a large risk-behavior screening study with a sample of 4,693 public high school students (mean age = 16.11, 47 % female). The study's findings showed that both physical bullying and cyber bullying associated with substance use, violent behavior, unsafe sexual behavior, and suicidal behavior. Substance use, violent behavior, and unsafe sexual behavior also all associated with suicidal behavior. Substance use and violent behavior partially mediated the relationship between both forms of bullying and suicidal behavior. The comparable amount of variance in suicidal behavior accounted for by both cyber bullying and physical bullying underscores the important of further cyber bullying research. The direct association of each risk behavior with suicidal behavior also underscores the importance of reducing risk behaviors. Moreover, the role of violence and substance use as mediating behaviors offers an explanation of how risk behaviors can increase an adolescent's likelihood of suicidal behavior through habituation to physical pain and psychological anxiety.

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

Substance use and suicide attempts are high-risk behaviors in adolescents, with serious impacts on health and well-being. Although multiple substance use among young people has become a common phenomenon, studies of its association with suicide attempts are scarce. The present study examines the association between multiple substance use and self-reported suicide attempts in a large multinational sample of adolescent students in Europe. Data on multiple substance use (tobacco, alcohol, tranquillizers/sedatives, cannabis, other illegal drugs) and self-reported suicide attempts were drawn from the 2007 European School Survey Project on Alcohol and Other Drugs (ESPAD). The ESPAD survey follows a standardized methodology in all participating countries. The present study is based on 45,086 16-year-old adolescents from 16 countries that had used the optional "psychosocial module" of the questionnaire, thereby including the question on suicide attempts. Logistic regression analyses were performed to examine the associations of any self-reported suicide attempt (dependent variable) with substance use controlling for country and gender. The strongest association with self-reported suicide attempts was for any lifetime tranquillizer or sedative use (odds ratio 3.34, 95 % confidence interval 3.00-3.71) followed by any lifetime use of illegal drugs other than cannabis (2.41, 2.14-2.70), 30-day regular tobacco use (2.02, 1.84-2.21), 30-day frequent alcohol use (1.47, 1.32-1.63) and any 30-day cannabis use (1.37, 1.18-1.58). The odds ratio of reporting a suicide attempt approximately doubled for every additional substance used. These findings on the association between multiple substance use, including legal drugs (tranquillizers or sedatives and tobacco), and the life-threatening behavior of suicide attempts provide important cues for shaping prevention policies.

Youth recovery contexts: the incremental effects of 12-step attendance and involvement on adolescent outpatient outcomes

BACKGROUND

A major barrier to youth recovery is finding suitable sobriety-supportive social contexts. National studies reveal most adolescent addiction treatment programs link youths to community 12-step fellowships to help meet this challenge, but little is known empirically regarding the extent to which adolescents attend and benefit from 12-step meetings or whether they derive additional gains from active involvement in prescribed 12-step activities (e.g., contact with a sponsor and other fellowship members). Greater knowledge in this area would enhance the efficiency of clinical continuing care recommendations.

METHODS

Adolescent outpatients (N = 127; M age 16.7; 75% male; 87% white) enrolled in a naturalistic study of treatment effectiveness were assessed at intake and 3, 6, and 12 months later using standardized assessments. Mixed-effects models, controlling for static and time-varying confounds, examined the concurrent and lagged effects of 12-step attendance and active involvement on abstinence over time.

RESULTS

The proportion attending 12-step meetings was relatively low across follow-up (24 to 29%), but more frequent attendance was independently associated with greater abstinence in concurrent and, to a lesser extent, lagged models. An 8-item composite measure of 12-step involvement did not enhance outcomes over and above attendance, but separate components did; specifically, greater contact with a 12-step sponsor outside of meetings and more verbal participation during meetings.

CONCLUSIONS

The benefits of 12-step participation observed among adult samples extend to adolescent outpatients. Community 12-step fellowships appear to provide a useful sobriety-supportive social context for youths seeking recovery, but evidence-based youth-specific 12-step facilitation strategies are needed to enhance outpatient attendance rates.

Adolescents' self-reported suicide attempts, self-harm thoughts and their correlates across 17 European countries

BACKGROUND

  Suicide is a leading cause of death among adolescents in Europe. Self-harm thoughts and behaviours are documented precursors of completed suicide. It is therefore of great importance to investigate the prevalence of suicide thoughts and attempts and their correlates, with the aim of preventing this major life-threatening public health problem. This study provides cross-national European data on self-reported suicidal thoughts and attempts among adolescents.

METHODS

  Data were obtained from 45,806 high school students aged 15-16 years from 17 countries that participated in the European School Survey Project on Alcohol and Other Drugs (ESPAD) 2007 school survey. The standardised methods of the ESPAD survey ensure comparability across countries. Students completed an anonymous questionnaire in their classrooms. The prevalences of suicidal thoughts and attempts are reported as well as their sociodemographic and psychosocial correlates identified in logistic regression.

RESULTS

  The median prevalence of any lifetime self-reported suicide attempt was 10.5% across the participating countries (range 4.1%-23.5%). The median of frequent self-harm thoughts (at least five times) was 7.4% (range 2.1%-15.3%). Suicidal behaviour and thoughts had significant associations with gender, substance use, family integrity and socioeconomic status. Countries with higher prevalence of substance use tended to have a weaker association between substance use and self-reported suicide attempts.

CONCLUSION

  Although self-reported self-harm thoughts and suicide attempts vary in prevalence within Europe, there are common correlates across countries. These have an important impact on understanding the phenomenon of suicide among young people and in guiding prevention.

Are Suicidal Phenomena in Children Different to Suicidal Phenomena in Adolescents? A Six-Year Review

BACKGROUND

  There has been little published about the nature and frequency of suicidal phenomena in children compared to that of adolescents.

METHOD

  Standardised information on all presentations with suicidal phenomena to the Children's University Hospital, Dublin from 2002 to 2008 were retrospectively analysed from a centralised database.

RESULTS

  During the time period of the study, 401 young people presented for assessment, of whom 21.9% (N = 88) were under 12 years of age. Children differed from adolescents in terms of gender distribution, method of self-harm, and risk factors present.

CONCLUSION

  Children under 12 are capable of displaying suicidal phenomena and differ considerably to adolescents in this regard.

Suicide and its association with individual, family, peer, and school factors in an adolescent population in southern Taiwan

A representative sample of 10,233 adolescent students was recruited to examine the rate of suicidal attempt and its correlates in the adolescents living in southern Taiwan. Five questions from the Kiddie Schedule for Affective Disorders and Schizophrenia (Kiddie-SADS-E) were used to inquire about the participants' suicidality. The associations between suicidal attempt and multidimensional factors were examined by using logistic regression analysis: 9.1% of the participants reported a suicidal attempt in the preceding year. Female gender, low self-esteem, weekly alcohol use, illicit drugs use, depression, high family conflict, low maternal education level, poor family function, low connectedness to school, low rank, poor feeling in peer group, and drop out from school were associated with adolescent suicidal attempt. The rate of suicidal attempt was found to be high in Taiwanese adolescents, and multidimensional factors were correlated to adolescent suicidal attempt.

Fatal suicide cases in Port Said city, Egypt

In the present study, a retrospective evaluation of suicide cases in the city of Port Said from 1998 to 2004 is done. The demographic data of the cases were evaluated. There were 80 cases of suicide 54 of them (67.5%) involved males. Age distribution showed a predominance in the age range 20-30 years. Methods of suicide included rodenticides intake in 25% of cases, drowning in 18.75%, burns in 16.25%, firearm injuries in 13.75%, jumping from height in 10%, drug intake in 8.75% and hanging in 7.5%. A medico-legal autopsy had been carried out for all cases. In conclusion, we emphasize the importance of rodenticides control as well as necessity of performing a psychological autopsy.

Risk factors for suicide attempts among Korean adolescents

This study examined the rate of suicide attempts and relevant variables and identified risk factors for suicide attempts among Korean adolescents. A cross-sectional study was performed using an anonymous, self-report questionnaire. A total of 2,100 Korean adolescents, including 1,321 student adolescents and 779 delinquent adolescents, were selected using a proportional stratified random sampling method for this study. The results showed the rate of suicide attempts to be 11.6%, with delinquent adolescents reporting a higher rate of suicide attempts than student adolescents. Adolescent suicide attempts indicated higher levels of dysfunctional family dynamics and maladaptive personalities. In addition, adolescents who attempted suicide expressed a significantly lower level of life satisfaction and less effective coping strategies compared with those adolescents who had not attempted suicide. Logistic regression analysis revealed that five predictive risk factors appeared to be statistically significant: coping strategy, parental child-rearing pattern, depression, parent-child relationship, and psychosomatic symptoms, in this order at p < 0.05.

Substance use behavior and suicide indicators among rural middle school students

BACKGROUND

This study provides a descriptive profile of substance use behavior and the prevalence of suicide indicators (thought about, considered, and planned) among rural middle school students and examines the association between substance use and suicidal indicators among middle school students participating in the Coordinated School Health Program in a rural state.

METHODS

During April and May 2004, 10,273 middle school students completed the middle school Youth Risk Behavior Survey.

RESULTS

This study found that a large percentage of students had initiated substance use behavior, with the greatest number of students having tried cigarettes (40.9% females and 42.7% males), followed by alcohol use (37.2% females and 41.3% males). Additionally, suicidal ideation and behavior were prevalent. Significant associations were found between substance use and suicidal ideation and behavior among middle school students.

CONCLUSIONS

Prevention programs for adolescent suicide should be implemented during the middle school years and should focus on preventing substance use given its relationship to suicide.

Two generations of Slovenian suicidal adolescent inpatients

BACKGROUND

The political and socio-economic situation in Slovenia, a former Yugoslav republic, a country in transition and a country with a high suicide rate, which joined the European Union in 2004, has changed steadily since the beginning of the 1970s. Literature shows constancy in suicide statistics in Slovenia during these times.

AIM

The present study examines whether the suicidal adolescent inpatient population in Slovenia reflects recent social changes and upheavals.

METHOD

Data on two groups of patients admitted to a specialized adolescent psychiatry department after attempting suicide were collected. The first group (n = 74) were patients admitted from 1975 to 1977, the second group (n = 73) from 2002 to 2004. They were compared on general characteristics, family and living circumstances, risk behaviors, suicide attempts and diagnoses.

RESULTS

The comparison revealed statistically significant differences between groups on educational level, number of siblings, frequency of smoking and psychoactive medication misuse as well as number of previous suicide attempts. No differences were found in other family and living circumstances, methods used in the index suicide attempt, other risk behaviors or diagnoses.

CONCLUSIONS

The post-independence suicidal inpatient population in Slovenia shows a tendency towards higher morbidity, but has changed less than expected considering the vast changes in the society. These results suggest a certain constancy in adolescent suicidal behavior.

Suicidal behavior among adolescents with conduct disorder--the role of alcohol dependence

Our aim was to investigate the association between alcohol dependence and suicidal behavior among adolescent girls and boys suffering from conduct disorder (CD). The original study sample consisted of 387 adolescents (age 12-17) admitted to psychiatric inpatient care between April 2001 and May 2005. DSM-IV-based psychiatric diagnoses and variables measuring suicidal behavior were obtained from the Schedule for Affective Disorders and Schizophrenia for School Aged Children--Present and Lifetime (K-SADS-PL). Of the total study population, 59 adolescent girls and 82 boys had CD according to DSM-IV criteria. Of all adolescents with CD, 24 (40.7%) girls and 24 (29.3%) boys were suffering from alcohol dependence. Among girls with CD, alcohol dependence increased the risk for suicide attempts up to 3.8-fold (95% CI 1.1-13.4). Among boys with CD, alcohol dependence increased the risk for life-threatening suicide attempt over nine-fold (95% CI 1.2-80.1). In addition, the risk for self-mutilative behavior was as high as 3.9-fold (95% CI 1.1-13.8) among girls and 5.3-fold (95% CI 1.1-26.5) among boys. The results indicate that, among adolescents suffering from CD, the risk of suicidal behavior is considerably increased by co-morbid alcohol dependence, which should therefore be carefully taken into account in clinical work.

Adolescent alcohol use and suicide indicators among adolescents in Hawaii

Research on suicide has focused on gender, age, ethnicity, and psychiatric profiles. However, few studies have examined alcohol use and its relationship to suicide among Native Hawaiians and other Asian American/Pacific Islanders. This study analyzes data from the 1997 and 1999 Hawaii Youth Risk Behavior Survey to examine whether alcohol problems increase the risk for suicide indicators (as evidenced by responses to questions asking whether an individual has considered, planned, attempted, or required treatment for a suicide attempt). Drinking pattern was the best predictor for all suicide indicators. School and community-based programs can help to increase an adolescent's knowledge about the consequences of alcohol use and prevention of suicide.

Time trends in child and adolescent mental disorders

PURPOSE OF REVIEW

1995 saw the publication of a major review of time trends in psychosocial disorders of youth across the second half of the twentieth century. It found evidence for substantial increases in rates of youth crime, alcohol and drug use, depression and suicide in most industrialized countries in the decades following the Second World War, slowing in some instances in the 1980s. Ten years on, we review findings on more recent trends in rates of these and other indicators of child and adolescent mental health.

RECENT FINDINGS

Prevalence estimates for autism spectrum disorders have increased in recent decades, as has public and professional awareness of hyperactivity and attention deficits. Trends in adolescent conduct problems, and in alcohol and drug use, appear to reflect culture-specific influences. Rates of suicide among young males, and self-harm among females have risen in many countries in recent years; trends in emotional disorders are more varied, but there is little evidence for any rise in rates of anorexia nervosa. Although some contributors to these trends have been identified, much remains to be learned about the key risks involved.

SUMMARY

Monitoring time trends in child and adolescent mental health is essential for service planning; knowledge of changing trends can also provide important pointers to potential risk factors. Current data sources allow relatively reliable tracking of trends in some areas, but remain severely limited in others. Further research is needed to understand the mechanisms underlying recently identified trends in child and adolescent mental health.

Substance use and suicidal conduct: a study of adolescents hospitalized for suicide attempt and ideation

AIM

To study the prevalence of psychoactive substance use disorder (PSUD) among suicidal adolescents, psychoactive substance intoxication at the moment of the attempt, and the association between PSUD at baseline and either occurrence of suicide or repetition of suicide attempt(s).

METHODS

186 adolescents aged 16 to 21 y hospitalized for suicide attempt or overwhelming suicidal ideation were included (T0); 148 of them were traced again for evaluations after 6 mo (T1) and/or 18 mo (T2). DSM-IV diagnoses were assessed each time using the Mini International Neuropsychiatric Interview.

RESULTS

At T0, 39.2% of the subjects were found to have a PSUD. Among them, a significantly higher proportion was intoxicated at the time of the attempt than those without PSUD (44.3% vs 25.4%). Among the 148 adolescents who could be traced at either T1 or T2, two died from suicide and 30 repeated suicide attempts once or more times. A marginally significant association was found between death by suicide/repetition of suicide attempt and alcohol abuse/dependence at baseline (OR=3.3, 95% CI 0.7-15.0; OR=2.6, 95% CI 0.7-9.3). More than one suicide attempt before admission to hospital at T0 (OR=3.2, 95% CI 1.1-10.0) and age over 19 y at T0 (OR=3.2, 95% CI 1.1-9.2) were independently associated with the likelihood of death by suicide or repetition of suicide attempt.

CONCLUSION

Among adolescents hospitalized for suicide attempt or overwhelming suicidal ideation, the risk of death or repetition of attempt is high and is associated with previous suicide attempts--especially among older adolescents--and also marginally associated with PSUD; these adolescents should be carefully evaluated for such risks and followed up once discharged from the hospital.

Parasuicide in a low-income country: results from three-year hospital surveillance in Nicaragua

AIMS

A study was undertaken to assess the incidence of parasuicide in Nicaragua, to identify groups at risk, and to describe the characteristics of parasuicides, such as methods used and seasonal and diurnal patterns.

METHOD

All hospital-admitted parasuicide cases in the area of Leon, Nicaragua, were assessed over a three-year period using standardized instruments.

RESULTS

Two hundred and thirty-three parasuicide cases were identified in the catchment area giving a parasuicide rate of 66.3/100,000 inhabitants per year based on the population 10 years and older. Corresponding figure for 15 years and older was 71.3. A majority were females (68.8%), who were significantly younger than the males (mean 20.8 years vs. mean 24.6 years). The highest rates were found in the age group 15-19 years with a female rate three times higher than the male rate (302.9 vs. 98.9). Pesticides, a highly lethal substance, were used as method in 19.1% of the attempts. Consistent seasonal variation with peaks in May-June and September-October were found over the years. Among parasuicide cases, 46.5% had been in contact with the healthcare system within 6 months before attempting suicide.

CONCLUSIONS

Parasuicides represent a significant health problem among young people in Nicaragua. Preventive efforts should be directed especially towards the life situation for young girls, limitation of availability of suicide means, increased awareness in schools concerning suicidal problems, as well as improved management of patients with mental health problems within primary healthcare.

Intoxicants and suicidal behaviour among adolescents: changes in levels and associations from 1992 to 2002

AIMS

To assess whether a substantial increase in substance use over a 10-year period has had an impact on the level of, or associations with, non-fatal suicidal behaviour among Norwegian teenagers.

DESIGN, SETTING AND PARTICIPANTS

Two cross-sectional school surveys applying identical procedures and measures in 1992 and 2002, using national samples comprising 11 000 and 12 000 13-19-year-old students.

FINDINGS

A significant proportion of the increase in the prevalence of attempted suicide among girls could be attributed to the increase in substance use, taking into account other risk and protective factors. Among boys no net increase in the prevalence of attempted suicide was observed, and the impact of substance use on suicidal behaviour was lower in 2002 than in 1992. Yet, it also appeared that unobserved protective factors may have countered the impact of increased substance use among boys. For both genders a larger fraction of attempted suicides was attributable to alcohol intoxication than to use of any other substance.

CONCLUSIONS

A significant increase in use of alcohol and drugs may not necessarily be reflected in changes in the level of suicidal behaviour. Further studies applying other data sources and designs are warranted to supplement and validate the present findings.

Changes in referrals to child and adolescent psychiatric services in Norway 1992--2001

BACKGROUND

The study analyzes changes in types of problems referred to child and adolescent psychiatry in Norway from 1992 to 2001, and investigates if referral practices and media attention account for these changes.

METHOD

All referrals to child and adolescent psychiatry in Norway in the period 1992--2001 were analyzed, as well as frequencies of articles in media on psychiatric problems.

RESULTS

The shares of referrals for sadness/depression increased from 0.5 % to 15.4 %. Referrals for hyperactivity/attention problems increased from 1.2 % to 13.6 %. The increases could be statistically attributed to decreased use of other referral categories, and/or alternatively to media attention on these and related topics. Convergence between diagnosis and corresponding referral problem increased in the period.

CONCLUSIONS

Referrals for sadness/depression and hyperactivity/attention problems increased sharply in Norway during the 1990s. This increase may be attributed to a different understanding of and a sharper look at these problems by referral agencies and by increased media attention.

Trends in adolescent suicide mortality in the WHO European Region

Trends in adolescent suicide rates (15-19 years) from 1979 to 1996 were compared with suicide trends in individuals of 20 years and over in 30 countries and with trends in rates of deaths due to undetermined causes in adolescents in 17 countries of the WHO European Region. In 21 of the 30 studied countries, male adolescent suicide rates increased during the study period (highest increases in Belarus, Kazakstan and Ireland) accompanied by far less increases or decreases in suicide rates of males of 20 years and over. Part of the observed increases in Sweden, Ireland and Greece can be attributed to improved suicide statistics, while increases in Finland, Belgium, Bulgaria and the United Kingdom can be even higher due to the rising classification of deaths as "undetermined". In Portugal, decreasing suicide trends seem to be misinterpreted by ignoring the vast increases in rates of undetermined deaths. Female adolescent suicide rates rose less markedly than in males in 18 countries, with the exception of strong increases in Norway, Ireland. Increases in female adolescent suicide rates were marginally affected by changes in classification practices and were accompanied primarily by declining suicide rates in females of 20 years and over.

Depressive symptoms and suicidal behaviour: changes with time in an adolescent clinic cohort

OBJECTIVE

There are suggestions of a secular increase in the prevalence of depression, self-harm and suicidal behaviour in young people. This study aims to examine changes in prevalence of psychological disturbance over time in adolescents referred for treatment.

METHOD

Data on the type and severity of emotional and behavioural problems was measured using the Youth Self-Report and Child Behaviour Checklist in 4495 clinic-referred adolescents aged 12-17 years, born in a 21-year period (1966-1986).

RESULTS

After taking into account the confounding effects of age and gender, there were significant increases in reports of self-harm and suicidal ideation (5% and 4% increase in odds per year, respectively) according to parents, but there was no change in parental ratings of depression (anxious/depressed scale). There were no changes in ratings of self-harm, suicidal ideation or anxiety/depression when adolescent reports were considered. The mean age at the time of referral decreased with increasing year of birth, from 14.6 years in those born in 1966-1971, to 13.1 years in those born in 1981-1986.

CONCLUSIONS

Parents of referred adolescents reported increasing self-harm and suicidal behaviour with increasing year of birth. In contrast, there were no changes over time in the adolescents' reports. Neither parents nor children reported an increase in depressive symptoms. Perceptions of a secular increase may reflect increasing parental awareness of some behaviours, particularly self-harm and suicidal ideation. Interpretation of these results needs to be cautious given the clinical origin of the sample.

Challenging times: a study to detect Irish adolescents at risk of psychiatric disorders and suicidal ideation

Suicide rates in young Irish males have risen markedly in the past 10 years, and suicide is now the leading cause of death in young men in the 15-24-year-old age range. This is the first large-scale study in Ireland that set out to identify young people at risk of psychiatric disorders, including depressive disorders, and suicidal ideation. Seven hundred and twenty three school-going adolescents aged 12-15 years were screened using the Children's Depression Inventory and the Strengths and Difficulties Questionnaire. 19.4% were identified as being 'at risk' of having a mental health disorder. Of this 'at risk' group, 12.1% expressed possible suicidal intent and 45.7% expressed suicidal ideation. Of the 583 adolescents identified as being 'not at risk', 13% expressed suicidal ideation while none expressed suicidal intent. Being 'at risk' was not related to gender or to socio-economic status. Those living with two parents were significantly more likely to be in the 'not at risk' group. Girls attending co-educational schools were twice as likely to be in 'at risk' group compared with those attending all girls schools, while school type was not a risk factor for boys. This study shows that, as in other western countries, there are large numbers of young Irish people at risk of mental health disorders and suicidal ideation in the community, and raises the question of the importance of mental health promotion in our education system.

Comorbidity in young people: perspectives and challenges

Trends in prevalence in substance misuse in young people in the UK are described: increased use over the last decade, the tendency to polydrug use, the narrowing of the gender gap. The complex issues relating to the description, definition and classification, and diagnosis of psychiatric comorbidity and substance misuse are outlined. The fact that there is no uniformly accepted definition of what constitutes 'dual diagnosis' or 'psychiatric comorbidity' in young people is highlighted: this variability impacts upon clinical assessment and study design. Despite these considerable drawbacks, a degree of consistency is beginning to emerge in the co-occurrence of some conditions, e.g. disruptive and suicidal behaviours. It is recognized that psychological distress and substance misuse are also associated with multiple social and physical complications. The rapid advances in treatment options are presented. At present the 'best practice' is implementation of what works for adults with addiction and young people with psychiatric disorder. This includes psychosocial interventions such as motivational enhancement techniques and cognitive behavioural treatment, as well as appropriate safe (usually), short-term use of a range of pharmacological agents. Very few comprehensive designated adolescent addiction services exist, while child and adolescent mental health services are under serious pressure. Thus the need for a longitudinal and multidisciplinary approach, with appropriate assessment instruments in young people, is required to further explore diagnostic classification which will classify the degrees and patterns of relationships between disorders. In this way it may be possible to build up a picture of the nature and extent of numerous complex, and sometimes overlapping, problems and needs in children and adolescents in a variety of settings: primary and secondary care, the criminal justice system and educational establishments. This might strengthen the development of innovative treatment services where novel interventions are tested as a priority.

The determinants of attempted suicide in a general hospital setting in Fiji Islands: a gender-specific study

The objective of the study was to examine the sociodemographic and clinical factors influencing gender-specific attempted suicide. Suicide attempters, 40 males and 88 females, seen on a consultation-liaison psychiatric service over a period of 42 months (from January 1, 1999 to June 30, 2002) were compared on sociodemographic and clinical variables. The female attempters [22.99 years (SD 8.1)] were younger than their male counterparts [25.15 years (SD 9.5)] [P = 0.0002]. A higher proportion of the male attempters were engaged in outside occupations, compared with their female counterparts who were mainly full-time housewives or engaged in domestic duties [P = 0.003]. Alcohol misuse was more associated with male suicide attempts [P = 0.001]. Ninety percent of male attempters and 54.6% of the female attempters had the intention to die [P = 0.001]. Although depressive episode was the most common psychiatric disorder in male attempters, followed by neurotic and stress-related disorders, while neurotic and stress-related disorders ranked first in female attempters followed closely by depressive episode, the difference was not significant. However, significantly more male attempters required pharmacotherapy and psychological intervention than their female counterparts [P = 0.002]. More females had marital difficulties, although comparing the two groups on social difficulties did not yield a significant difference. Method used, personality disorders, previous attempt, repeat attempt, race, religion, and marital status were not significant distinguishing factors. Younger age, lack of employment outside home, marital problems, and nondeath motives were more influential in female attempted suicide, while alcohol misuse and severe psychiatric morbidity were more frequently associated with male attempted suicide. The findings support gender-specific preventive and interventional strategies.

Adolescent's suicide attempts: populations at risk, vulnerability, and substance use

Adolescence corresponds to a transition period that requires adaptation and change capacities and skills. Most young people succeed with this challenge, whereas a minority fail. In order to identify with the teenage culture, become autonomous, and differentiate from their parents, some adolescents choose to use drugs, beginning with the use of cigarettes, alcohol, cannabis, followed by other illicit drugs such as opiates and stimulants. A high proportion of these adolescents attempt suicide, which is the primary cause of death during adolescence in many European countries. Who are the "vulnerable" adolescents? What are the mechanisms that can explain the varieties of drug-use initiation or suicide attempts? Can "protective factors" be identified? What kind of strategies might be developed at a social and political level in order to prevent or to minimize drug abuse and suicide attempts, among other harmful behaviors? These issues will be discussed on the basis of the recent literature and in the light of a recent study carried out in the French-speaking part of Switzerland on large cohorts of adolescent drug users. Unresolved critical issues are noted and future needed research is suggested.

Drug use and suicide attempts: the role of personality factors

This study on suicide attempts is part of a large research project on dependent behavior in adolescents and young adults. 228 subjects aged 14-25 (107 "drug abusers," 121 controls) from the French speaking part of Switzerland were evaluated on the basis of a semi-structured interview (Mini International Neuropsychiatric Interview), enabling a DSM-IV diagnosis, and self-reports (SSS by Zuckermann, MMPI-2, IDI by Hirschfeld). 31.5% of "drug abuser" males and 41.2% of "drug abuser" females committed one or more suicide attempts. The results of a logistic regression show that the significant factor explaining suicide attempts in drug users is emotional reliance for males and experience-seeking for females.

Suicidal ideation, psychiatric disorder, and medical illness in a community epidemiological study

Many epidemiological studies have analyzed suicidal ideation in clinical samples, but only a few have been performed in the general population. We present the results of a two-stage epidemiological study in the general population on the island of Formentera (Balearic Islands, Spain), which used the 28-item General Health Questionnaire (GHQ-28) in the first stage (n = 697) and the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) in the second (n = 242). We also recorded medical illnesses diagnosed in the subjects at the second stage. Four items on the GHQ-28 ask directly about suicidal thoughts or ideation. From the sample, 6.5% have reported suicidal ideation. Mental disorders are the most important factor associated with suicidal ideation; medical illnesses seem to play a secondary role.

Suicide attempts in the "comprehensive community mental health services for children and their families" program

OBJECTIVE

To compare clinical characteristics of youths who had attempted suicide recently, previously but not recently, repeatedly, or never.

METHOD

The sample comprised 4,677 youths receiving services between 1993 to 1998 in 22 communities and participating in the national evaluation of the Comprehensive Community Mental Health Services for Children and Their Families Program. Data on suicide attempts, demographics, and clinical characteristics were obtained from intake interviews and referring agencies. Chi-square and univariate analyses of variance were used for between-group comparisons.

RESULTS

Twenty-one percent of the sample had a history of attempted suicide. Previous and repeat attempters were more likely to have a history of family violence and substance abuse. Repeat attempters were most likely to have depression, while never and previous (but not recent) attempters were more likely to have conduct disorder. Other clinical differences were also found.

CONCLUSIONS

Among children receiving mental health services, those who attempt suicide experience more and different types of distress, depending on the recency and frequency of attempts. Clinicians should be aware that depression is not a necessary factor in predicting suicide attempts and that suicide risk is also associated with violent and aggressive behaviors.

The Maudsley long-term follow-up of child and adolescent depression. 1. Psychiatric outcomes in adulthood

BACKGROUND

Strong links exist between juvenile and adult depression but comorbid conduct disorder in childhood may mitigate this continuity.

AIMS

To test the impact of comorbid conduct disorder on psychiatric adult outcomes.

METHOD

A group of 149 subjects assessed at the Maudsley Hospital in the period 1970-1983 and meeting DSM-IV criteria for major depressive disorder with (n=53) or without (n=96) conduct disorder were interviewed 20 years later. Data were collected on the lifetime history of psychiatric disorders.

RESULTS

Adult depressive recurrence was high for major depression (62.4%) and any depression (75.2%), and survival analyses showed no difference between the two groups. The group with conduct disorders had higher rates of drug misuse and dependence, alcoholism and antisocial personality disorders.

CONCLUSIONS

Adolescent depression carries an elevated risk of adult depression irrespective of comorbidity. Comorbid conduct disorder in childhood is associated with raised rates of other psychiatric outcomes.

Attempted suicide by drug overdose and by poison-ingestion methods seen at the main general hospital in the Fiji islands: a comparative study

OBJECTIVE

This study examined the prevalence and the characteristics of deliberate self-poisoning patients seen at the main general hospital in the Fiji Islands.

METHOD

Thirty-one consecutive patients with deliberate drug-overdose and 27 others with nonoverdosed self-poisoning were compared on sociodemographic and clinical variables.

RESULTS

Deliberate self-poisoning cases represented 0.3% of the hospital admissions, and had a rate of 25.9 per 100,000 population. The overdose group was significantly older (P<.05), whereas the poison-ingestion group had significantly greater proportion of males (P<.03). The rate of psychiatric morbidity was significantly higher in the overdose group (P=.04), whereas the history of alcohol abuse was significantly higher in the other group (P=.04). Paracetamol (35.5%) and paraquat (29.7%) were the most commonly used agents.

CONCLUSIONS

Age, gender, rate of psychiatric morbidity, or history of alcohol abuse could be predictive of whether drug overdose or poison ingestion would be used for deliberate self-poisoning. This information could be relevant in the formulation of suicide preventive strategies.

Suicide in children and adolescents in England and Wales 1970-1998

BACKGROUND

Suicide rates for England and Wales have been decreasing recently, but rates for young adult males remain high.

AIMS

To review changes in suicide rates for children and adolescents in England and Wales between 1970 and 1998.

METHOD

Rates for suicide, 'accidental' death by causes similar to suicide and 'undetermined' death for 10-14- and 15-19-year-olds are calculated between 1970 and 1998 using suicide data and estimated mid-year populations obtained from the Office for National Statistics.

RESULTS

There has been a substantial increase in suicide rate between the 1970s and the 1990s for males aged 15-19 years. This remains true even when 'undetermined' and 'accidental' death rates for causes similar to suicide are examined. The increase was associated with an increase in self-poisoning with vehicle exhaust gas in the 1980s and an increase in hanging which has continued into the 1990s. Although there was a slight decrease in the official suicide rate for females aged 15-19 years, 'undetermined' deaths increased. There is no indication of a major change in suicide rate in 10-14-year-olds.

CONCLUSIONS

The substantial increase in suicide rate in 15-19-year-old males may indicate increased psychosocial stress, particularly affecting this group.

The characteristics of suicide attempters admitted to the main general hospital in Fiji Islands

OBJECTIVE

To study the characteristics of suicide attempters attending the main general hospital in Fiji Islands.

METHOD

Consecutive suicide attempters were clinically evaluated, and their sociodemographic and clinical characteristics were compared with those of other patients seen in the psychiatric service between January 15, 1999 and January 14, 2000.

RESULTS

Thirty-nine suicide attempters were seen, representing 36.8% of all the cases referred to the psychiatric service. The prevalence of attempted suicide in the Greater Suva Area was 34.8 per 100,000. Majority (56.4%) were young (16-25 years), Indians (59%), female (61.5%), students (41%), never married (74.4%) and of Hindi faith (48.7%). The commonly used methods were ingestion of drugs and pesticides. The intention to die was present in 20 (51.3%) of the population. Social problems and/or psychiatric comorbidity were present in over 60% of cases. Suicide attempters were significantly younger, more of single persons (P<.0001), and fewer were in employment (P<.001) than nonsuicidal cases seen. The difference was not significant when the two groups were compared regarding gender, race or religion.

CONCLUSIONS

Young people attempt suicide in disturbed psychosocial milieu, using available poisoning methods with strong desire to die. Apparently, high proportion of female Indians in this group reflects high rate of service utilization by them. Unemployment is an insignificant predisposing factor.

The association of suicide attempts and comorbid depression and substance abuse in psychiatric consultation patients

Substance abuse has been associated with attempted suicide and suicide. Few studies have examined the prevalence and associations of combined depression and substance abuse in suicide attempters. A chart review study of 1136 adult general hospital patients referred for psychiatric consultation between 1995 and 1998 was conducted to assess this further. Among 371 cases with self-harm, 311 (84%) attempted suicide. Suicide attempters were younger and diagnosed more often with comorbid substance abuse than patients without self-harm. Depressive disorders were found in 59% and substance abuse disorders in 46%. Comorbid depression and substance abuse was the most frequent category in suicide attempters, i.e., in 37%. Self-reported suicide intent was associated with increasing age, male gender, and comorbid depression and substance abuse. The suicide rate in suicide attempters was 322 per 100,000 patient-years, and 131 per 100,000 in consultation patients without self-harm. It is concluded that comorbid depression and substance abuse is associated with attempted suicide in psychiatric consultation patients. Suicide attempters should be thoroughly assessed for substance abuse. The increased suicide rate in psychiatric consultation patients with and without suicide attempts warrants further research.

Waiting for harm: deliberate self-harm and suicide in young people--a review of the literature

Mental health professionals, particularly nurses, practicing in child and adolescent psychiatry are key players in the continued development of expertise, awareness and understanding of deliberate self-harm (DSH) and suicide in young people. Enhancing this knowledge and the associated skills will contribute to effective, therapeutic relationships with individuals and their families. The purpose of this paper is to review the current literature surrounding the issue of deliberate self-harm and suicide in young people. The paper will address national and international studies selected from a variety of child and adolescent and general psychiatric literature. The research presented highlights important issues to be addressed in practice. In particular, the evidence supports the influence of mental illness in DSH and suicide, particularly depression and substance abuse. However, a clearly important factor is an individual's experience of family and social life. The literature is considered in the light of relevant governmental policy documents relating to DSH and suicide. The future role of the mental health nurse in child and adolescent psychiatry in the United Kingdom (UK) is discussed in the contexts of family work and assessment.

Neurodevelopmental antecedents of early-onset bipolar affective disorder

BACKGROUND

Developmental impairments have been identified as a risk factor for early-onset schizophrenia. Affective symptoms are more common in children and adolescents with disordered neurodevelopmental than in healthy controls.

AIMS

To test the hypothesis that severe early-onset mood disorders are associated with developmental antecedents.

METHOD

We retrospectively identified 38 adolescent cases (15 female, 23 male; mean age 14.4 years, range 11-18) who met ICD-10 Research Diagnostic Criteria for a manic episode, bipolar affective disorder or psychotic depression, and 41 controls (25 female, 16 male, mean age 14.2 years, range 11-18) with depression but without psychotic features.

RESULTS

Cases were significantly more likely to have experienced delayed language, social or motor development (OR 5.5, 95% CI = 1.4-21.6, P = 0.01), in particular those who develop psychotic symptoms (OR 7.2, 95% CI = 1.8-28.6, P = 0.003).

CONCLUSIONS

Compared to early-onset unipolar depression, neurodevelopmental antecedents are over-represented in early-onset bipolar disorder. The validity of this finding was supported by contemporaneous IQ scores that are not subject to the same potential biases as case-note ratings.
