Preventive interventions for youth suicide: a risk factor-based approach

Effectiveness of school-based preventive programs in suicidal thoughts and behaviors: A meta-analysis

BACKGROUND

Suicidal thoughts and behaviors (STBs) among adolescents have hardly decreased despite preventative efforts. School-based prevention programs could have a great reach, yet suicide prevention is not an easy topic to address. To increase acceptability of school-based suicide prevention, it is important to evaluate whether programs that target known risk factors of STBs, such as depression, could be equally effective.

METHODS

We conducted a systematic literature search in major electronic databases. Outcomes were suicidal ideation and behaviors. Multivariate random effects meta-regression-analyses were conducted.

RESULTS

Eleven primary studies met the inclusion criteria, totalling 23,230 participants. The post-test effect size was small for both suicidal ideation (g = 0.15) and suicidal behaviors (g = 0.30). Meta-regression indicated that targeting known risk factors of STBs was not a significant modifier of effect size for ideation, indicating equal effectiveness. However, it was significant modifier of effect for behaviors, but only one intervention targeted know risk factors. Effects at follow-up (3-12 months) were also significant but small for both outcomes.

LIMITATIONS

Substantial heterogeneity between studies was noted. Only few and small sample size studies could be included that targeted known risk factors of STBs. Therefore, these results should be interpreted with caution.

CONCLUSIONS

School-based prevention of STBs shows some promise within three months post-test assessments, and potentially also have effects that are sustained over time. More studies are needed to make conclusions regarding school-based interventions that target risk factors of STBs.

Exploration of associations between deliberate self-poisoning and psychiatric disorders in rural Sri Lanka: A case-control study

Psychiatric disorders are important predictors of deliberate self-harm. The present study was carried out to determine the associations between DSM-IV TR Axis- I & II disorders and deliberate self-poisoning (DSP) in a rural agricultural district in Sri Lanka. Patients residing in the district who presented with DSP were randomly selected for the study. Both the cases and age, sex, and, residential area, matched controls were assessed for DSM-IV TR Axis- I & II disorders based on the Structured Clinical Interview for DSM-IV-TR Axis I and II Disorders (SCID I & II) conducted by a specialist psychiatrist. Cases consisted of 208 (47.4%) males and 231 (52.6%) females. More than one third (37%) of males and more than half (53.7%) of females were aged below 20 years. DSM-IV TR axis-I and/or II psychiatric diagnoses were diagnosed in 89 (20.3%) of cases and 14 (3.2%) controls. Cases with a DSM-IV TR axis-I diagnosis were older than the cases without psychiatric diagnosis (32 and 19 years), p<0.0001. Having a depressive episode was associated with a 19 times higher risk for DSP. Being a male aged > = 30 years and having an alcohol use disorder carried a 21 times excess risk for DSP. A fivefold excess risk for DSP was found among 10-19 year old females with borderline personality traits. Depressive disorder and alcohol-related disorders were significantly associated with the older participants who presented with DSP. The overall prevalence of psychiatric disorders associated with DSP in rural Sri Lanka was significantly lower compared to the rates reported in the West and other countries in the region. Therefore, health and research priorities to reduce self-harm in Sri Lanka should focus both on psychiatric and non-psychiatric factors associated with DSP.

School-based gatekeeper training programmes in enhancing gatekeepers' cognitions and behaviours for adolescent suicide prevention: a systematic review

Suicide is a leading cause of death in adolescence. School provides an effective avenue both for reaching adolescents and for gatekeeper training. This enables gatekeepers to recognize and respond to at-risk students and is a meaningful focus for the provision of suicide prevention. This study provides the first systematic review on the effectiveness of school-based gatekeeper training in enhancing gatekeeper-related outcomes. A total of 815 studies were identified through four databases (Ovid Medline, Embase, PsycINFO and ERIC) using three groups of keywords: 'school based', 'Suicide prevention programme' and 'Gatekeeper'. Fourteen of these studies were found to be adequate for inclusion in this systematic review. The improvement in gatekeepers' knowledge; attitudes; self-efficacy; skills; and likelihood to intervene were found in most of the included studies. Evidence of achieving improvement in attitudes and gatekeeper behaviour was mixed. Most included studies were methodologically weak. Gatekeeper training appears to have the potential to change participants' knowledge and skills in suicide prevention, but more studies of better quality are needed to determine its effectiveness in changing gatekeepers' attitudes. There is also an urgent need to investigate how best improvements in knowledge and skills can be translated into behavioural change.

Youth mental ill health and secondary school completion in Australia: time to act

AIM

This paper reviews the evidence of youth mental ill health and its impact on secondary school educational attainment.

METHODS

This narrative review presents the current research related to the mental ill health of young people in urban and rural Australia, their educational attainment and the effectiveness of mental health strategies implemented in secondary schools.

RESULTS

The prevalence of mental ill health is high for Australian young people and the onset of depression, anxiety, substance-use disorders and first episode psychosis (FEP) commonly occurs when the individual is at school. The prevalence is reported to be higher for rural young people and barriers to treatment exist. Current evidence suggests that 40% of young people experiencing depression or anxiety disorders are not completing secondary school. Further evidence shows that over 50% of individuals who experience FEP do not finish secondary school. Current mental health promotion strategies employed in secondary schools have not been shown to reduce rates of depression or anxiety in adolescence nor identify prodromal or acute FEP. These strategies have not led to interventions that assist young people with mental ill health to finish school.

CONCLUSIONS

Not completing secondary school can limit employment options, lead to severe levels of disadvantage and increased burden on welfare and healthcare systems. All young people, including those in rural areas, have the right to education and should not be disadvantaged in their educational aspirations because they have an emerging or current mental illness.

Teachers' Perspectives on Preventing Suicide in Children and Adolescents in Schools: A Qualitative Study

Given the important role teachers play as gatekeepers in school suicide prevention, this study explored teachers' perspectives on what should be done to improve current suicide prevention efforts. The study, in Queensland, Australia, was part of a large-scale survey examining teachers' knowledge, attitudes and experience of suicidality. One hundred and fifteen teachers responded to an online survey question regarding their views on the requirements for school suicide prevention. Qualitative analysis identified five themes from teachers' responses: awareness and stigma reduction, support services for students, education and training, bullying and the role of social media. The results of this study provide some profound insights into teachers' perspectives on suicide and highlight the critical need for improved suicide prevention efforts in schools.

The infected self: Revisiting the metaphor of the mind virus

The idea that units of culture may act as a virus controlling some of the perceptions and actions of individuals has been the subject of considerable controversy since proposed by evolutionary biologist Richard Dawkins. This debate has occurred in the absence of a defined mental viral structure or a target body upon which such viral structures may act. This article develops a paradigm in which the self is understood as such a body upon which future research into “mind viruses” may be undertaken. Possible mechanisms for mind-viral transmission are discussed. Criteria for defining a mental virus are used to examine evidence of possible mind-virus contagion in suicides, suicide cults, terrorism, and religion.

Development of ACROSSnet: an online support system for rural and remote community suicide prevention workers in Queensland, Australia

Communication and information technologies can reduce the barriers of distance and space that disadvantage communities in Australia's underserved rural areas, where the health status of residents is often worse than that of their urban counterparts. ACROSSnet (Australians Creating Rural Online Support Systems) is a 3 year collaborative action research project that aims to design and develop an online support system that will assist rural communities in accessing information, education and support regarding suicide and its prevention, whilst considering the challenges of Internet speed, cost and availability that can impede the delivery of online services. The site provides three distinct levels of access: one level for community members, and two further levels for appropriately credentialled mental health workers. In creating this environment, the ACROSSnet team hopes that online communities of practice will develop, engaging participants of different ages, income and education levels, location, and socioeconomic backgrounds.

Psychosocial interventions for self-harm in adults

BACKGROUND

Self-harm (SH; intentional self-poisoning or self-injury) is common, often repeated, and associated with suicide. This is an update of a broader Cochrane review first published in 1998, previously updated in 1999, and now split into three separate reviews. This review focuses on psychosocial interventions in adults who engage in self-harm.

OBJECTIVES

To assess the effects of specific psychosocial treatments versus treatment as usual, enhanced usual care or other forms of psychological therapy, in adults following SH.

SEARCH METHODS

The Cochrane Depression, Anxiety and Neurosis Group (CCDAN) trials coordinator searched the CCDAN Clinical Trials Register (to 29 April 2015). This register includes relevant randomised controlled trials (RCTs) from: the Cochrane Library (all years), MEDLINE (1950 to date), EMBASE (1974 to date), and PsycINFO (1967 to date).

SELECTION CRITERIA

We included RCTs comparing psychosocial treatments with treatment as usual (TAU), enhanced usual care (EUC) or alternative treatments in adults with a recent (within six months) episode of SH resulting in presentation to clinical services.

DATA COLLECTION AND ANALYSIS

We used Cochrane's standard methodological procedures.

MAIN RESULTS

We included 55 trials, with a total of 17,699 participants. Eighteen trials investigated cognitive-behavioural-based psychotherapy (CBT-based psychotherapy; comprising cognitive-behavioural, problem-solving therapy or both). Nine investigated interventions for multiple repetition of SH/probable personality disorder, comprising emotion-regulation group-based psychotherapy, mentalisation, and dialectical behaviour therapy (DBT). Four investigated case management, and 11 examined remote contact interventions (postcards, emergency cards, telephone contact). Most other interventions were evaluated in only single small trials of moderate to very low quality.There was a significant treatment effect for CBT-based psychotherapy compared to TAU at final follow-up in terms of fewer participants repeating SH (odds ratio (OR) 0.70, 95% confidence interval (CI) 0.55 to 0.88; number of studies k = 17; N = 2665; GRADE: low quality evidence), but with no reduction in frequency of SH (mean difference (MD) -0.21, 95% CI -0.68 to 0.26; k = 6; N = 594; GRADE: low quality).For interventions typically delivered to individuals with a history of multiple episodes of SH/probable personality disorder, group-based emotion-regulation psychotherapy and mentalisation were associated with significantly reduced repetition when compared to TAU: group-based emotion-regulation psychotherapy (OR 0.34, 95% CI 0.13 to 0.88; k = 2; N = 83; GRADE: low quality), mentalisation (OR 0.35, 95% CI 0.17 to 0.73; k = 1; N = 134; GRADE: moderate quality). Compared with TAU, dialectical behaviour therapy (DBT) showed a significant reduction in frequency of SH at final follow-up (MD -18.82, 95% CI -36.68 to -0.95; k = 3; N = 292; GRADE: low quality) but not in the proportion of individuals repeating SH (OR 0.57, 95% CI 0.21 to 1.59, k = 3; N = 247; GRADE: low quality). Compared with an alternative form of psychological therapy, DBT-oriented therapy was also associated with a significant treatment effect for repetition of SH at final follow-up (OR 0.05, 95% CI 0.00 to 0.49; k = 1; N = 24; GRADE: low quality). However, neither DBT vs 'treatment by expert' (OR 1.18, 95% CI 0.35 to 3.95; k = 1; N = 97; GRADE: very low quality) nor prolonged exposure DBT vs standard exposure DBT (OR 0.67, 95% CI 0.08 to 5.68; k = 1; N =18; GRADE: low quality) were associated with a significant reduction in repetition of SH.Case management was not associated with a significant reduction in repetition of SH at post intervention compared to either TAU or enhanced usual care (OR 0.78, 95% CI 0.47 to 1.30; k = 4; N = 1608; GRADE: moderate quality). Continuity of care by the same therapist vs a different therapist was also not associated with a significant treatment effect for repetition (OR 0.28, 95% CI 0.07 to 1.10; k = 1; N = 136; GRADE: very low quality). None of the following remote contact interventions were associated with fewer participants repeating SH compared with TAU: adherence enhancement (OR 0.57, 95% CI 0.32 to 1.02; k = 1; N = 391; GRADE: low quality), mixed multimodal interventions (comprising psychological therapy and remote contact-based interventions) (OR 0.98, 95% CI 0.68 to 1.43; k = 1 study; N = 684; GRADE: low quality), including a culturally adapted form of this intervention (OR 0.83, 95% CI 0.44 to 1.55; k = 1; N = 167; GRADE: low quality), postcards (OR 0.87, 95% CI 0.62 to 1.23; k = 4; N = 3277; GRADE: very low quality), emergency cards (OR 0.82, 95% CI 0.31 to 2.14; k = 2; N = 1039; GRADE: low quality), general practitioner's letter (OR 1.15, 95% CI 0.93 to 1.44; k = 1; N = 1932; GRADE: moderate quality), telephone contact (OR 0.74, 95% CI 0.42 to 1.32; k = 3; N = 840; GRADE: very low quality), and mobile telephone-based psychological therapy (OR not estimable due to zero cell counts; GRADE: low quality).None of the following mixed interventions were associated with reduced repetition of SH compared to either alternative forms of psychological therapy: interpersonal problem-solving skills training, behaviour therapy, home-based problem-solving therapy, long-term psychotherapy; or to TAU: provision of information and support, treatment for alcohol misuse, intensive inpatient and community treatment, general hospital admission, or intensive outpatient treatment.We had only limited evidence on whether the intervention had different effects in men and women. Data on adverse effects, other than planned outcomes relating to suicidal behaviour, were not reported.

AUTHORS' CONCLUSIONS

CBT-based psychological therapy can result in fewer individuals repeating SH; however, the quality of this evidence, assessed using GRADE criteria, ranged between moderate and low. Dialectical behaviour therapy for people with multiple episodes of SH/probable personality disorder may lead to a reduction in frequency of SH, but this finding is based on low quality evidence. Case management and remote contact interventions did not appear to have any benefits in terms of reducing repetition of SH. Other therapeutic approaches were mostly evaluated in single trials of moderate to very low quality such that the evidence relating to these interventions is inconclusive.

Interventions for self-harm in children and adolescents

BACKGROUND

Self-harm (SH; intentional self-poisoning or self-injury) is common in children and adolescents, often repeated, and strongly associated with suicide. This is an update of a broader Cochrane review on psychosocial and pharmacological treatments for deliberate SH first published in 1998 and previously updated in 1999. We have now divided the review into three separate reviews; this review is focused on psychosocial and pharmacological interventions for SH in children and adolescents.

OBJECTIVES

To identify all randomised controlled trials of psychosocial interventions, pharmacological agents, or natural products for SH in children and adolescents, and to conduct meta-analyses (where possible) to compare the effects of specific treatments with comparison types of treatment (e.g., treatment as usual (TAU), placebo, or alternative pharmacological treatment) for children and adolescents who SH.

SEARCH METHODS

For this update the Cochrane Depression, Anxiety and Neurosis Group (CCDAN) Trials Search Co-ordinator searched the CCDAN Specialised Register (30 January 2015).

SELECTION CRITERIA

We included randomised controlled trials comparing psychosocial or pharmacological treatments with treatment as usual, alternative treatments, or placebo or alternative pharmacological treatment in children and adolescents (up to 18 years of age) with a recent (within six months) episode of SH resulting in presentation to clinical services.

DATA COLLECTION AND ANALYSIS

Two reviewers independently selected trials, extracted data, and appraised study quality, with consensus. For binary outcomes, we calculated odds ratios (OR) and their 95% confidence intervals (CI). For continuous outcomes measured using the same scale we calculated the mean difference (MD) and 95% CI; for those measured using different scales we calculated the standard mean difference (SMD) and 95% CI. Meta-analysis was only possible for two interventions: dialectical behaviour therapy for adolescents and group-based psychotherapy. For these analyses, we pooled data using a random-effects model.

MAIN RESULTS

We included 11 trials, with a total of 1,126 participants. The majority of participants were female (mean = 80.6% in 10 trials reporting gender). All trials were of psychosocial interventions; there were none of pharmacological treatments. With the exception of dialectical behaviour therapy for adolescents (DBT-A) and group-based therapy, assessments of specific interventions were based on single trials. We downgraded the quality of evidence owing to risk of bias or imprecision for many outcomes.Therapeutic assessment appeared to increase adherence with subsequent treatment compared with TAU (i.e., standard assessment; n = 70; k = 1; OR = 5.12, 95% CI 1.70 to 15.39), but this had no apparent impact on repetition of SH at either 12 (n = 69; k = 1; OR 0.75, 95% CI 0.18 to 3.06; GRADE: low quality) or 24 months (n = 69; k = 1; OR = 0.69, 05% CI 0.23 to 2.14; GRADE: low quality evidence). These results are based on a single cluster randomised trial, which may overestimate the effectiveness of the intervention.For patients with multiple episodes of SH or emerging personality problems, mentalisation therapy was associated with fewer adolescents scoring above the cut-off for repetition of SH based on the Risk-Taking and Self-Harm Inventory 12 months post-intervention (n = 71; k = 1; OR = 0.26, 95% CI 0.09 to 0.78; GRADE: moderate quality). DBT-A was not associated with a reduction in the proportion of adolescents repeating SH when compared to either TAU or enhanced usual care (n = 104; k = 2; OR 0.72, 95% CI 0.12 to 4.40; GRADE: low quality). In the latter trial, however, the authors reported a significantly greater reduction over time in frequency of repeated SH in adolescents in the DBT condition, in whom there were also significantly greater reductions in depression, hopelessness, and suicidal ideation.We found no significant treatment effects for group-based therapy on repetition of SH for individuals with multiple episodes of SH at either the six (n = 430; k = 2; OR 1.72, 95% CI 0.56 to 5.24; GRADE: low quality) or 12 month (n = 490; k = 3; OR 0.80, 95% CI 0.22 to 2.97; GRADE: low quality) assessments, although considerable heterogeneity was associated with both (I(2) = 65% and 77% respectively). We also found no significant differences between the following treatments and TAU in terms of reduced repetition of SH: compliance enhancement (three month follow-up assessment: n = 63; k = 1; OR = 0.67, 95% CI 0.15 to 3.08; GRADE: very low quality), CBT-based psychotherapy (six month follow-up assessment: n = 39; k = 1; OR = 1.88, 95% CI 0.30 to 11.73; GRADE: very low quality), home-based family intervention (six month follow-up assessment: n = 149; k = 1; OR = 1.02, 95% CI 0.41 to 2.51; GRADE: low quality), and provision of an emergency card (12 month follow-up assessment: n = 105, k = 1; OR = 0.50, 95% CI 0.12 to 2.04; GRADE: very low quality). No data on adverse effects, other than the planned outcomes relating to suicidal behaviour, were reported.

AUTHORS' CONCLUSIONS

There are relatively few trials of interventions for children and adolescents who have engaged in SH, and only single trials contributed to all but two comparisons in this review. The quality of evidence according to GRADE criteria was mostly very low. There is little support for the effectiveness of group-based psychotherapy for adolescents with multiple episodes of SH based on the results of three trials, the evidence from which was of very low quality according to GRADE criteria. Results for therapeutic assessment, mentalisation, and dialectical behaviour therapy indicated that these approaches warrant further evaluation. Despite the scale of the problem of SH in children and adolescents there is a paucity of evidence of effective interventions. Further large-scale trials, with a range of outcome measures including adverse events, and investigation of therapeutic mechanisms underpinning these interventions, are required. It is increasingly apparent that development of new interventions should be done in collaboration with patients to ensure that these are likely to meet their needs. Use of an agreed set of outcome measures would assist evaluation and both comparison and meta-analysis of trials.

Pharmacological interventions for self-harm in adults

BACKGROUND

Self-harm (SH; intentional self-poisoning or self-injury) is common, often repeated, and strongly associated with suicide. This is an update of a broader Cochrane review on psychosocial and pharmacological treatments for deliberate SH, first published in 1998 and previously updated in 1999. We have now divided the review into three separate reviews. This review is focused on pharmacological interventions in adults who self harm.

OBJECTIVES

To identify all randomised controlled trials of pharmacological agents or natural products for SH in adults, and to conduct meta-analyses (where possible) to compare the effects of specific treatments with comparison types of treatment (e.g., placebo/alternative pharmacological treatment) for SH patients.

SEARCH METHODS

For this update the Cochrane Depression, Anxiety and Neurosis Review Group (CCDAN) Trials Search Co-ordinator searched the CCDAN Specialised Register (September 2014). Additional searches of MEDLINE, EMBASE, PsycINFO, and CENTRAL were conducted to October 2013.

SELECTION CRITERIA

We included randomised controlled trials comparing pharmacological treatments or natural products with placebo/alternative pharmacological treatment in individuals with a recent (within six months) episode of SH resulting in presentation to clinical services.

DATA COLLECTION AND ANALYSIS

We independently selected trials, extracted data, and appraised trial quality. For binary outcomes, we calculated odds ratios (ORs) and their 95% confidence intervals (CIs). For continuous outcomes we calculated the mean difference (MD) and 95% CI. Meta-analysis was only possible for one intervention (i.e. newer generation antidepressants) on repetition of SH at last follow-up. For this analysis, we pooled data using a random-effects model. The overall quality of evidence for the primary outcome was appraised for each intervention using the GRADE approach.

MAIN RESULTS

We included seven trials with a total of 546 patients. The largest trial included 167 participants. We found no significant treatment effect on repetition of SH for newer generation antidepressants (n = 243; k = 3; OR 0.76, 95% CI 0.42 to 1.36; GRADE: low quality of evidence), low-dose fluphenazine (n = 53; k = 1; OR 1.51, 95% CI 0.50 to 4.58; GRADE: very low quality of evidence), mood stabilisers (n = 167; k = 1; OR 0.99, 95% CI 0.33 to 2.95; GRADE: low quality of evidence), or natural products (n = 49; k = 1; OR 1.33, 95% CI 0.38 to 4.62; GRADE: low quality of evidence). A significant reduction in SH repetition was found in a single trial of the antipsychotic flupenthixol (n = 30; k = 1; OR 0.09, 95% CI 0.02 to 0.50), although the quality of evidence for this trial, according to the GRADE criteria, was very low. No data on adverse effects, other than the planned outcomes relating to suicidal behaviour, were reported.

AUTHORS' CONCLUSIONS

Given the low or very low quality of the available evidence, and the small number of trials identified, it is not possible to make firm conclusions regarding pharmacological interventions in SH patients. More and larger trials of pharmacotherapy are required. In view of an indication of positive benefit for flupenthixol in an early small trial of low quality, these might include evaluation of newer atypical antipsychotics. Further work should include evaluation of adverse effects of pharmacological agents. Other research could include evaluation of combined pharmacotherapy and psychological treatment.

Feasibility and effectiveness of a web-based positive psychology program for youth mental health: randomized controlled trial

BACKGROUND

Youth mental health is a significant public health concern due to the high prevalence of mental health problems in this population and the low rate of those affected seeking help. While it is increasingly recognized that prevention is better than cure, most youth prevention programs have utilized interventions based on clinical treatments (eg, cognitive behavioral therapy) with inconsistent results.

OBJECTIVE

This study explores the feasibility of the online delivery of a youth positive psychology program, Bite Back, to improve the well-being and mental health outcomes of Australian youth. Further aims were to examine rates of adherence and attrition, and to investigate the program's acceptability.

METHODS

Participants (N=235) aged 12-18 years were randomly assigned to either of two conditions: Bite Back (n=120) or control websites (n=115). The Bite Back website comprised interactive exercises and information across a variety of positive psychology domains; the control condition was assigned to neutral entertainment-based websites that contained no psychology information. Participants in both groups were instructed to use their allocated website for 6 consecutive weeks. Participants were assessed pre- and postintervention on the Depression Anxiety Stress Scale-Short form (DASS-21) and the Short Warwick-Edinburgh Mental Well-Being Scale (SWEMWBS).

RESULTS

Of the 235 randomized participants, 154 (65.5%) completed baseline and post measures after 6 weeks. Completers and dropouts were equivalent in demographics, the SWEMWBS, and the depression and anxiety subscales of the DASS-21, but dropouts reported significantly higher levels of stress than completers. There were no differences between the Bite Back and control conditions at baseline on demographic variables, DASS-21, or SWEMWBS scores. Qualitative data indicated that 49 of 61 Bite Back users (79%) reported positive experiences using the website and 55 (89%) agreed they would continue to use it after study completion. Compared to the control condition, participants in the Bite Back condition with high levels of adherence (usage of the website for 30 minutes or more per week) reported significant decreases in depression and stress and improvements in well-being. Bite Back users who visited the site more frequently (≥3 times per week) reported significant decreases in depression and anxiety and improvements in well-being. No significant improvements were found among Bite Back users who demonstrated low levels of adherence or who used the website less frequently.

CONCLUSIONS

Results suggest that using an online positive psychology program can decrease symptoms of psychopathology and increase well-being in young people, especially for those who use the website for 30 minutes or longer per week or more frequently (≥3 times per week). Acceptability of the Bite Back website was high. These findings are encouraging and suggest that the online delivery of positive psychology programs may be an alternate way to address mental health issues and improve youth well-being nationally.

TRIAL REGISTRATION

Australian New Zealand Clinical Trials Registry: ACTRN1261200057831; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=362489 (Archived by Webcite at http://www.webcitation.org/6NXmjwfAy).

Outcome of a school-based intervention to promote life-skills among young people in Cambodia

BACKGROUND

Most of the school-based interventions to prevent suicide are from high income countries and there is a need for evidence based interventions in resource-poor settings. The aim of this study is to evaluate the outcome of a school based intervention to reduce risk factors for suicide among young people in Cambodia by promoting life skills.

METHOD

Six classes were randomly selected from two schools each, one designated as experimental and the other as control school, respectively. In experimental school 168 young people (M=92, F=76) received 6 sessions of life skills education and in the control school 131 students (M=53, F=78) received three general sessions on health. We looked at the pre-post differences on Life-Skills Development Scale Adolescent Form (LSDS-AF)- and Youth Self-Report (YSR) questionnaire to measure the effect size (ES) from the intervention after 6 months. We analyzed the data by stratifying for gender and for those who reported more severe suicidal expressions at baseline (high-risk group).

RESULTS

The girls showed improvement in Human Relationship (ES=0.57), Health Maintenance (ES=0.20) and the Total Life Skills Dimensions (ES=0.24), whereas boys with high-risk behavior improved on Human Relationship (ES=0.48), Purpose in Life (ES=0.26) and Total Life Skills Dimensions (ES=0.22). Effect size for YSR-syndrome scores among all individuals showed no improvement for either gender. Among high-risk individuals boys had a small to moderate effect size from intervention on Withdrawn/Depressed (ES=0.40), Attention problems (ES=0.46), Rule breaking behavior (ES=0.36), Aggressive behavior (ES=0.48) and Externalizing syndrome (ES=0.64).

CONCLUSION

Promoting life skills in schools may enhance the overall mental health of young people, indirectly influencing suicide, particularly among boys with high-risk behavior in Cambodia.

Mapping the evidence of prevention and intervention studies for suicidal and self-harming behaviors in young people

BACKGROUND

Suicide and self-harm (SSH) in young people is a major cause of disability-adjusted life years. Effective interventions are of critical importance to reducing the mortality and morbidity associated with SSH.

AIMS

To investigate the extent and nature of research on interventions to prevent and treat SSH in young people using evidence mapping.

METHOD

A systematic search for SSH intervention studies was conducted (participant mean age between 6-25 years). The studies were restricted to high-quality evidence in the form of systematic reviews, meta-analyses, and controlled trials.

RESULTS

Thirty-eight controlled studies and six systematic reviews met the study inclusion criteria. The majority (n = 32) involved psychological interventions. Few studies (n = 9) involved treating young people with recognized mental disorders or substance abuse (n = 1) which also addressed SSH.

CONCLUSION

The map was restricted to RCTs, CCTs, systematic reviews, and meta-analyses, and thus might have neglected important information from other study designs. The effectiveness of interventions within the trials was not evaluated. The evidence base for SSH interventions in young people is not well established, which hampers best-practice efforts in this area. Promising interventions that need further research include school-based prevention programs with a skills training component, individual CBT interventions, interpersonal psychotherapy, and attachment-based family therapy. Gaps in the research exist in evaluations of interventions for SSH in young people with identifiable psychopathology, particularly substance use disorder, and research that classifies participants on the basis of their suicidal intent.

A retrospective of publications addressing suicidal behaviour in the Australian and New Zealand Journal of Psychiatry, 1967-2012

OBJECTIVE

To review publications addressing suicidal behaviour in the Australian and New Zealand Journal of Psychiatry, 1967-2012.

METHOD

A PubMed/MEDLINE search using the words suicide, attempted suicide (and their synonyms) and Aust NZ J Psychiatr was carried out, and an examination of all tables of contents of the journal for the years 1967-2012 was performed.

RESULTS

In 342 (7.4%) of 4599 articles there was reference to suicidal behaviour. This ratio was consistent over time, although the nature of their content changed from broader epidemiological and clinical review studies to more focused reports.

CONCLUSIONS

Papers addressing suicidal behaviour have been published consistently in the Australian and New Zealand Journal of Psychiatry since its inception in 1967. Early clinical reviews remain pertinent to the present time.

School-wide staff and faculty training in suicide risk awareness: successes and challenges

PROBLEM

Rates of youth suicide and suicidal behavior remain high despite prevention efforts. Training high school personnel as gatekeepers is an important strategy.

METHODS

Training was implemented in a school district's five comprehensive high schools. Surveys were conducted before and after training sessions, which targeted all adults working at the high school. Two hundred thirty-seven individuals completed the pretest and/or posttest.

FINDINGS

Participants reported gains in knowledge, confidence, and feelings of competence in recognizing, approaching, and connecting distressed youth to school-based resources. Training was well received.

CONCLUSION

Training is acceptable and appropriate for school personnel. Increasing the number of school personnel who participate in the training is challenging.

A randomized controlled trial of a senior centre group programme for increasing social support and preventing depression in elderly people living at home in Norway

BACKGROUND

Late-life depression is a common condition and a challenging public health problem. A lack of social support is strongly associated with psychological distress. Senior centres seem to be suitable arenas for community-based health promotion interventions, although few studies have addressed this subject. The objectives were to examine the effect of a preventive senior centre group programme consisting of weekly meetings, on social support, depression and quality of life.

METHODS

A questionnaire was sent to a random sample of 4,000 persons over 65 in Oslo, and a total of 2,387 completed questionnaires were obtained. These subjects served as a basis for recruitment of participants for a trial, with scores on HSCL-10 being used as a main inclusion criterion. A total of 138 persons were randomized into an intervention group (N = 77) and control group (N = 61). Final analyses included 92 persons. Social support (OSS-3), depression (BDI), life satisfaction and health were measured in interviews at baseline and after 12 months (at the end of the intervention programme). Perceptions of benefits from the intervention were also measured. Mean scores, SD, SE and CI were used to describe the changes in outcomes. Effect sizes were calculated based on the original scales and as Cohen's d. Paired sample tests and ANOVA were used to test group differences.

RESULTS

There was an increase in social support in both groups, but greatest in the intervention group. The level of depression increased for both groups, but more so in the control than the intervention group. There was a decrease in life satisfaction, although the decrease was largest among controls. There were almost no differences in reported health between groups. However, effect sizes were small and differences were not statistically significant. In contrast, most of the participants said the intervention meant much to them and led to increased use of the centre.

CONCLUSIONS

In all probability, the intervention failed to meet optimistic targets, but possibly met quite modest ones. Since intention-to-treat analysis was not possible, we do not know the effect on the intervention group as a whole. A further evaluation of these programmes is necessary to expand the group programme. For the depressed, more specialized programmes to cope with depression may be a more appropriate intervention.

Can receipt of a regular postcard reduce suicide-related behaviour in young help seekers? A randomized controlled trial

AIM

Suicide attempt, ideation and deliberate self-harm are common among adolescents. Limited evidence exists regarding interventions that can reduce risk; however, research indicates that maintaining contact with at-risk adults following discharge from services via letter or postcard can reduce risk. The aim of the study was to test a postcard intervention among people aged 15-24 who presented to mental health services but were not accepted, yet were at risk of suicide.

METHODS

A randomized controlled trial of 3 years in duration was used. The intervention consisted of 12 postcards sent once a month for 12 months following presentation to the service. Key outcomes of interest were reduced rates of suicide attempt, suicidal ideation and deliberate self-harm, assessed at 12 and 18 months.

RESULTS

Participants reported that they liked receiving the postcard and that they used the strategies recommended. However, no significant effect of the postcard intervention was found on suicide risk, although participants in both groups improved on measures of mental health over the course of the study.

CONCLUSIONS

There remains a need for further research into youth-friendly interventions for young people at risk of suicide.

Suicide attempt presentations at the emergency department: outcomes from a pilot study examining precipitating factors in deliberate self-harm and issues in primary care physician management

The aim of this study was to examine the psychosocial precipitating factors of people presenting to the emergency department (ED) due to attempted suicide. Demographic, diagnostic and service use data were collected for a 6-week period. All patients were referred for primary care physician (PCP) management, with a sample followed up for secondary analysis of precipitants to self-harm and follow-up outcomes. Results of the study showed that key psychosocial stressors that triggered suicidality were relationship issues and recent unemployment, with depression present in 92% of cases. While 83% of patients followed attended their first PCP appointment, 50% discontinued by 3 months. The conclusion of this study is that psychosocial crises and depression are key factors in suicide attempts. Assertive crisis intervention, facilitated linkage to community services, and greater monitoring are recommended.

Preliminary effectiveness of surviving the teens(®) suicide prevention and depression awareness program on adolescents' suicidality and self-efficacy in performing help-seeking behaviors

BACKGROUND

Suicide ranks as the third leading cause of death among youth aged 15-24 years. Schools provide ideal opportunities for suicide prevention efforts. However, research is needed to identify programs that effectively impact youth suicidal ideation and behavior. This study examined the immediate and 3-month effect of Surviving the Teens® Suicide Prevention and Depression Awareness Program on students' suicidality and perceived self-efficacy in performing help-seeking behaviors.

METHODS

High school students in Greater Cincinnati schools were administered a 3-page survey at pretest, immediate posttest, and 3-month follow-up. A total of 1030 students participated in the program, with 919 completing matched pretests and posttests (89.2%) and 416 completing matched pretests and 3-month follow-ups (40.4%).

RESULTS

Students were significantly less likely at 3-month follow-up than at pretest to be currently considering suicide, to have made a suicidal plan or attempted suicide during the past 3 months, and to have stopped performing usual activities due to feeling sad and hopeless. Students' self-efficacy and behavioral intentions toward help-seeking behaviors increased from pretest to posttest and were maintained at 3-month follow-up. Students were also more likely at 3-month follow-up than at pretest to know an adult in school with whom they felt comfortable discussing their problems. Nine in 10 (87.3%) felt the program should be offered to all high school students.

CONCLUSIONS

The findings of this study lend support for suicide prevention education in schools. The results may be useful to school professionals interested in implementing effective suicide prevention programming to their students.

Preventing adolescent suicide: a community takes action

Suicide is the third leading cause of death for adolescents and young people in the United States. The etiology of suicide in this population has eluded policy makers, researchers, and communities. Although many suicide prevention programs have been developed and implemented, few are evidence-based in their effectiveness in decreasing suicide rates. In one northern California community, adolescent suicide has risen above the state's average. Two nurses led an effort to develop and implement an innovative grassroots community suicide prevention project targeted at eliminating any further teen suicide. The project consisted of a Teen Resource Card, a community resource brochure targeted at teens, and education for the public and school officials to raise awareness about this issue. This article describes this project for other communities to use as a model. Risk and protective factors are described, and a comprehensive background of adolescent suicide is provided.

Predictors of suicidal behavior in a high school student population: a cross-sectional study

AIM

To examine high school students' suicidal behavior and to identify predictors of suicide attempt among adolescents in Timis County, Romania. We hypothesized that suicide attempt is associated with other health-risk behaviors.

METHODS

In this cross-sectional study we included 2908 high school students in grades 9 to 12. The students were asked to complete an anonymous structured questionnaire during a normal class. We examined the relationship between having attempted suicide and engaging in other health-risk or problem behaviors.

RESULTS

During the previous 12 months, 15.4% of the students had had suicidal ideation, 7.5% had made a suicide plan and 6.1% reported that they had attempted suicide. Based on logistic regression multivariate analysis, attempted suicide was associated with feeling sad or hopeless almost every day for two or more consecutive weeks (OR = 4.74; 95% CI: 3.07-7.31), being forced to have sexual intercourse (OR = 3.18; 95% CI: 1.83-5.50), being physically aggressed by his or her father (OR = 4.28; 95% CI: 1.96-9.34), performing poorly at school (OR = 4.22; 95% CI: 1.51-11.74), having an impaired relationship with parents (OR = 2.45; 95% CI: 1.17-5.12), not eating for 24 hours or more to lose weight or to avoid gaining weight during the past 30 days (OR = 2.23; 95% CI: 1.40-3.53), being female (OR = 1.91; 95% CI: 1.21-2.99) and carrying a weapon (OR = 2.44; 95% CI: 1.53-3.90).

CONCLUSION

This study suggests that suicide attempts are associated with other risk behaviors. These behaviors may help to evaluate suicide risk and should be considered when establishing preventive programs.

The impact of two universal randomized first- and second-grade classroom interventions on young adult suicide ideation and attempts

OBJECTIVE

This paper reports the impact of two first- and second-grade classroom based universal preventive interventions on the risk of Suicide Ideation (SI) and Suicide Attempts (SA) by young adulthood. The Good Behavior Game (GBG) was directed at socializing children for the student role and reducing aggressive, disruptive behavior. Mastery Learning (ML) was aimed at improving academic achievement. Both were implemented by the teacher.

METHODS

The design was epidemiologically based, with randomization at the school and classroom levels and balancing of children across classrooms. The trial involved a cohort of first-grade children in 19 schools and 41 classrooms with intervention at first and second grades. A replication was implemented with the next cohort of first grade children with the same teachers but with little mentoring or monitoring.

RESULTS

In the first cohort, there was consistent and robust GBG-associated reduction of risk for suicide ideation by age 19-21 years compared to youths in standard setting (control) classrooms regardless of any type of covariate adjustment. A GBG-associated reduced risk for suicide attempt was found, though in some covariate-adjusted models the effect was not statistically robust. No statistically significant impact on these outcomes was found for ML. The impact of the GBG on suicide ideation and attempts was greatly reduced in the replication trial involving the second cohort.

CONCLUSIONS

A universal preventive intervention directed at socializing children and classroom behavior management to reduce aggressive, disruptive behavior may delay or prevent onset of suicide ideation and attempts. The GBG must be implemented with precision and continuing support of teachers.

Telecommunication and suicide prevention: hopes and challenges for the new century

Development of information technology has created new opportunities and challenges in suicide prevention, research, and clinical practice. This article presents an overview of the wide range of telecommunication-based suicide prevention approaches. Interventions using the Internet, telephone, and videoconferencing are discussed, including crisis intervention, referral, and support, suicide risk assessment, psychotherapy for individuals at risk, and online-based suicide prevention training and education. Research regarding effectiveness of telecommunication-based suicide prevention in various demographic and clinical populations is reviewed, as well as concerns regarding this type of intervention. Future areas of research and development in the use of telecommunication media in prevention of suicide are discussed.

The role of randomized trials in testing interventions for the prevention of youth suicide

Epidemiological considerations point to a small handful of prevention strategies that have the potential for dramatically reducing suicide rates. Nearly all of those prevention approaches involve population-based strategies to either find an increased number of individuals at high risk for suicide or to reduce the prevalence of risk factors in members of a population that, as a whole, has a relatively low rate of suicide. Few of these approaches have been evaluated in rigorous trials. We argue that there are rigorous randomized trial designs that are both feasible and ethical and can be used to test both programmes and implementation strategies for population-based suicide prevention. We review existing suicide prevention trials and introduce two new randomized trial designs that are likely to achieve sufficient statistical power. The 'dynamic wait-listed design' randomizes across different time periods and is now being used to test a gatekeeper training programme in 32 schools. It could also be used to examine suicide prevention programmes in rural areas. The multi-trial follow-up study builds on the large number of successful population-based preventive interventions aimed at reducing known risk factors for suicide in youths to see whether these also cause a reduction in rates of completed suicide.

No-suicide contracts and no-suicide agreements: a controversial life

OBJECTIVE

In this paper we describe the origins of suicide prevention contracting, identify the historical factors that led to the adoption of the intervention, and describe legal tensions that have emerged during its use.

CONCLUSIONS

It would appear that one of the most frequently used clinical interventions for responding to suicidality has established a place in clinical practice without evidence attesting to its efficacy. We develop some propositions about how and why this clinical technique has been able to consolidate its place in mental health practice and, in so doing, suggest that the original technique was able to secure a clinical place without much apparent resistance because of the confluence of a number of emerging theories and community trends.

Clinical management of deliberate self-harm in young people: the need for evidence-based approaches to reduce repetition

OBJECTIVE

To examine the evidence for the effectiveness of clinical interventions designed to reduce the repetition of deliberate self-harm (DSH) in adolescents and young adults.

METHODS

Electronic databases were searched for papers describing randomised and clinical control trials (RCTs) and quasi-experimental studies of interventions targeting adolescents and young adults presenting to clinical services following DSH or suicidal ideation.

RESULTS

Three RCTs, four clinical control trials and three quasi-experimental studies were identified. Group therapy, trialled in a RCT, was the only specific programme which led to a significant reduction in rates of repetition of self-harm. Attendance at follow-up did not improve significantly regardless of the intervention, while one clinically controlled trial of intensive intervention resulted in poorer attendance at follow-up. One quasi-experimental study of family therapy resulted in a significant reduction in suicidal ideation.

CONCLUSIONS

The evidence base for treatments designed to reduce the repetition of self-harm in adolescents and young adults is very limited. Expensive interventions such as intensive aftercare offer no clear benefit over routine aftercare. Given that deliberate self-harm among young people is a common clinical problem further good quality treatment studies are warranted. Careful consideration should be given to process evaluation to determine which individual components of any given intervention are effective.

A survey of adolescents' knowledge about depression

Adolescent depression and suicide are major public health concerns. Best practices for suicide prevention and education in high schools are not well understood. The Adolescent Depression Awareness Program (ADAP) was developed to address depression education as an effective means towards decreasing the morbidity and mortality associated with adolescent depression. Adolescents' baseline knowledge about depression was assessed to enhance curriculum development. The survey was administered to 5,645 high school students between 1999 and 2003. Results indicated that students had a cursory knowledge of depression facts but had gaps in knowledge about treatment and symptom identification.

Australian and New Zealand clinical practice guidelines for the management of adult deliberate self-harm

BACKGROUND

The Royal Australian and New Zealand College of Psychiatrists is co-ordinating the development of clinical practice guidelines (CPGs) in psychiatry, funded under the National Mental Health Strategy (Australia) and the New Zealand Health Funding Authority.

METHOD

For these guidelines, the CPG Team for Deliberate Self-harm reviewed the treatment outcome literature (including meta-analyses) and consulted with practitioners and patients.

TREATMENT RECOMMENDATIONS

(i) Organization of general hospital services to provide: emergency department admission; a safe environment; integrated medical and psychiatric management; risk assessment; identification of psychiatric morbidity, and adequate follow-up. (ii) Detection and treatment of any psychiatric disorder. (iii) Dialectical behaviour therapy, psychoanalytically orientated partial hospitalization or home-based interpersonal therapy (for certain patients) to reduce repetition of deliberate self-harm (DSH).

CONCLUSION

Deliberate self-harm is common and is costly in terms of both individual distress and service provision. General hospitals are often the first point of clinical contact, but may not be appropriately organized to care for these patients. Evidence for the effectiveness of psychological treatments is based on single RCTs without replication. The three recommended psychological treatments are not widely available in Australia and New Zealand, and the interventions that are, such as cognitive behaviour therapy, problem solving and 'green cards' (an agreement guaranteeing access to services), do not reduce repetition of DSH. The effect of follow-up in psychiatric hospitals or in the community is poorly understood. We need to develop and evaluate interventions that will reduce repetition of both fatal and non-fatal deliberate self-harm and improve the person's functioning and quality of life.

Who are the kids who self-harm? An Australian self-report school survey

OBJECTIVE

To determine the prevalence and types of deliberate self-harm (DSH) in adolescents, and associated factors.

DESIGN

A cross-sectional questionnaire study.

PARTICIPANTS AND SETTING

3757 of 4097 Year 10 and Year 11 students (91.7%) from 14 high schools on the Gold Coast, Queensland, during September 2002.

MAIN OUTCOME MEASURES

DSH behaviour, including descriptions of the last act, psychological symptoms, recent stressors, coping styles, help-seeking behaviour, lifestyle choices, and self-prescribing of medications.

RESULTS

233 students (6.2%) met the criteria for DSH in the previous 12 months, with DSH more prevalent in females than males (OR, 7.5; 95% CI, 5.1-10.9). The main methods were self-cutting (138 respondents; 59.2%) and overdosing with medication (69 respondents; 29.6%). Factors associated with DSH included similar behaviours in friends or family, coping by self-blame, and self-prescribing of medications. Most self-harmers did not seek help before or after their most recent action, with those who did primarily consulting friends.

CONCLUSIONS

DSH is common in Australian youth, especially in females. Preventive programs should encourage young people to consult health professionals in stressful situations.

Telephone counselling for adolescent suicide prevention: changes in suicidality and mental state from beginning to end of a counselling session

Telephone counselling is an accessible and confidential means by which distressed young people can seek help. Telephone counselling services were funded under Australia's National Youth Suicide Prevention Strategy between 1997 and 2000. In this study, the effectiveness of telephone counselling for young people seeking help in the context of suicidal ideation or intent was evaluated in an investigation of calls made by suicidal young people to a telephone counselling service. Independent raters measured callers' suicidality and mental state at the beginning and end of 100 taped counselling sessions. Changes in suicidality and mental state were measured using a reliable rating scale developed for the study. Significant decreases in suicidality and significant improvement in mental state were found to occur during the course of counselling sessions, suggesting positive immediate impact. Limitations of the study with respect to longer-term outcomes and the relevance of the results for suicide prevention are discussed. Notwithstanding the study limitations, the results lend support for continuing development of hotline services.

Correlates of youth suicide attempters in Australian community and clinical samples

OBJECTIVE

This study (i) explores differences between a clinical sample of deliberate self-poisoning (DSP) patients and a community sample who reported previous attempted suicide (AS); and (ii) examines correlates of suicidal behaviour in these groups compared with a community control group (CC) with no suicidal behaviour.

METHOD

The study design was: case-case, case-control and cross-sectional population studies. A clinical sample of DSP (n = 51), a community sample of AS (n = 31) and a community sample with no suicidal behaviour (n = 842) were used, all aged 18-24 years. The DSP and AS groups were compared on several variables and two logistic regression models were developed for risk of (i) DSP and (ii) AS compared to community controls.

RESULTS

The adjusted odds ratios for DSP were: female gender (OR = 5.7, CI = 1.7-19.4), anxiety (OR = 7.4, CI = 2.2-25.1), affective (OR = 23.0, CI = 6.9-76.5), or substance-use disorder (OR = 19.2, CI = 5.6-65.4) and greater mental health related disability (OR = 0.5, CI = 0.3-0.7 for 1 SD decrease). For AS the results were: anxiety (OR = 9.4, CI = 1.7-52.8) or substance-use disorder (OR = 3.0, CI = 1.1-8.7) and greater mental health disability (OR = 0.5, CI = 0.4-0.7). Affective disorder was close to significant for the AS group (OR = 4.0, CI = 0.9-17.1).

CONCLUSIONS

Correlates of DSP/AS were usually more powerful in the clinical group, but showed a similar pattern of psychiatric disorder and disability factors in both groups, supporting a continuum of risk factors across these groups. Interventions based on modifiable risk factors could target the same factors for public health, primary care or hospital populations: anxiety, depression and substance use disorders and mental health related disability.

Repetition risk for adolescent self-poisoning: a multiple event survival analysis

OBJECTIVES

To examine risk factors associated with re-presentation (event rates) following an initial episode of hospital treated self-poisoning.

METHOD

A longitudinal cohort study using the Hunter Area Toxicology Service (HATS) database of all presentations to hospital of self-poisoned patients aged 10-19 in Newcastle and Lake Macquarie Regions of New South Wales from January 1991 to December 1995. The study factors were: age, gender, employment status, 'substance abuse' and psychiatric diagnosis at index (first documented episode during the study time-period) admission. The main outcome measure was re-presentations per unit time. Time-event analysis (multivariate) was used to compare re-presentation rates per person-year exposure to the study factors.

RESULTS

There were 450 patients who presented on a total of 551 occasions. The median and modal age at initial presentation was 17. Three hundred and nine (69%) were female and 141 (31%) were male. The probability (95% CI) of a patient re-presenting within one year of an index admission with self poisoning was 0.09 (0.07-0.12) and within 5 years was 0.16 (0.12-0.21). The adjusted rate ratios for episodes of re-presentation were: any 'substance abuse (ever)' 3.87 (2.08-7.21), 'alcohol abuse' 2.32 (1.15-4.68),'benzodiazepine abuse' 4.89 (1.63-14.62), schizophrenia and other psychotic disorders (DSM-IV) 2.85 (1.2-6.79), and any personality disorder (DSM-IV) 2.68 (1.73-4.16).

CONCLUSIONS

Interventions to decrease recurrence rates for adolescent self poisoning should be directed towards substance (particularly alcohol or benzodiazepine) abuse, non-affective psychoses and personality disorder.

Depression in young people: what causes it and can we prevent it?

Cumulative adverse experiences, including negative life events and early childhood adversity, together with parental depression and/or non-supportive school or familial environments, place young people at risk for developing depression. Enhanced life skills and supportive school and family environments can mediate the effect of stressful life events. Programs that enhance the school environment are associated with improved behaviour and wellbeing. Interventions that teach cognitive skills are associated with a short-term reduction in depressive symptoms. Current evidence suggests that for an intervention to be sustainable it must encompass multiple components across several levels: classroom, curriculum, whole school, and the school-community interface. Teaching interpersonal skills, including cognitive and problem-solving skills, should be coupled with the promotion of positive school and family environments to prevent depression in young people.

Gender differences in the relationship between depression and suicidal ideation in young adolescents

OBJECTIVE

This study examined the risk relationship between depressive symptomatology and suicidal ideation for young adolescent males and females.

METHOD

A large cohort of students in their first year of high school completed the Center for Epidemiological Studies Depression Scale (CES-D) and the Adolescent Suicide Questionnaire. The risk relationship between depressive symptomatology and suicidal ideation was modelled using non-parametric kernel-smoothing techniques.

RESULTS

Suicidal ideation was more frequently reported by females compared with males which was partly explained by females having higher mean depression scores. At moderate levels of depression females also had a significantly higher risk of suicidal ideation compared with males and this increased risk contributed to the overall higher levels of female ideation.

CONCLUSIONS

The risk relationship between depressive symptomatology and suicidal ideation is different for young adolescent males and females. The results indicate that moderate levels of depressive symptomatology can be associated with suicidal ideation (especially among young females) and that for these young people a suicide risk assessment is required.
