Effects of a Serious Game for Adolescent Mental Health on Cognitive Vulnerability: Pilot Usability Study

Background

Adolescent mental health is of utmost importance. E-mental health interventions, and serious games in particular, are appealing to adolescents and can have beneficial effects on their mental health. A serious game aimed at improving cognitive vulnerability (ie, beliefs or attitudes), which can predispose an individual to mental health problems, can contribute to the prevention of these problems in adolescents.

Objective

This study aimed to assess the feasibility of the prototype of a serious game called "Silver."

Methods

The prototype of the serious game was developed using a user-centered participatory design. The prototype of Silver focused on 1 aspect of a serious game for improving cognitive vulnerability in adolescents, that is, the recognition and identification of cognitive distortions. Through the game, players were required to identify and classify the character's thoughts as helpful or unhelpful. Upon successful advancement to the next level, the task becomes more challenging, as players must also identify specific types of cognitive distortions. A pre- and posttest uncontrolled design was used to evaluate the game, with a 1-week intervention phase in which participants were asked to play the game. Participants aged 12-16 years were recruited in schools. The outcomes of interest were the recognition of cognitive distortions and presence of participants' cognitive distortions. The game was also evaluated on its effects, content, and usefulness.

Results

A total of 630 adolescents played Silver and completed the assessments. Adolescents were significantly better at recognizing cognitive distortions at the pretest (mean 13.09, SD 4.08) compared to the posttest (mean 13.82, SD 5.09; t629=-4.00, P<.001). Furthermore, their cognitive distortions decreased significantly at the posttest (mean 38.73, SD 12.79) compared to the pretest (mean 41.43, SD 10.90; t629=7.98, P<.001). Participants also indicated that the game helped them recognize cognitive distortions. Many participants considered the game appealing (294/610, 48.2%) but boring (317/610, 52%) and preferred a more comprehensive game (299/610, 49%).

Conclusions

Findings from this study suggest that a serious game may be an effective tool for improving cognitive vulnerability in adolescents. The development of such a serious game, based on the prototype, is recommended. It may be an important and innovative tool for the universal prevention of mental health problems in adolescents. Future research on the effects of the game is warranted.

Evaluation of an online suicide prevention campaign targeting men

BACKGROUND

Men are at elevated risk of suicide compared to women. Adherence to traditional norms of masculinity can interfere with potential protective factors such as openness to talk and seeking social support, which can contribute to the increased suicide risk. An online public health campaign was developed to improve mental health among men and tackle the stigma surrounding it. This study aimed at examining whether the online suicide prevention campaign targeting men increased openness to talk about emotions and help-seeking behavior and decreased hopelessness and adherence to traditional gender norms concerning self-reliance.

METHOD

250 men (18+) from Flanders (Belgium) were recruited online and given access to the campaign website for a period of 3 days. Before and after viewing the campaign website, participants were asked to complete an online survey.

RESULTS

Viewing the campaign was associated with a small increase in help-seeking intention when experiencing suicidal thoughts. Among men who reported mental health problems, a small increase in openness to communicating and expressing emotions was found after viewing the campaign. In general, participants evaluated the campaign positively.

CONCLUSION

This study demonstrated the potential beneficial impact of an online prevention campaign specifically targeting men on health behaviors that may protect against suicidal behavior.

Mindfulness-Based Cognitive Therapy for Individuals Who Are Suicidal: A Randomized Controlled Trial

There is a need for well-described treatments targeting individuals at risk for suicidal behaviors. The present study aims to investigate the effectiveness of MBCT adapted to individuals who are suicidal (MBCT-S) in a randomized controlled trial, comparing an intervention group receiving MBCT-S and treatment as usual (TAU) with a control group receiving TAU only. Participants who were 18 years or older and experienced suicidal ideation were included. Assessments on suicidal ideation and symptoms associated with suicidal behavior were carried out at baseline, post-treatment, and 12 weeks after the end of the training. When comparing the intervention group with the control group, a significant reduction was found at follow-up in suicidal ideation and depressive symptoms. When focusing on the intervention group only, a significant reduction was found in suicidal ideation, depressive symptoms, hopelessness, worrying, defeat, and entrapment, and a significant increase in mindfulness both at post-treatment and at follow-up. The findings suggest that MBCT-S is a promising suicide-specific intervention as it may have the potential to reduce suicidal ideation and suicide-related components.

Future-Oriented Group Training for suicidal individuals: A randomized controlled trial

INTRODUCTION

Suicide is a serious public health concern worldwide. Current psychological interventions targeting suicidal ideation and behavior are, however, limited and often lack convincing empirical support. Future-Oriented Group Training (FOGT) targets crucial aspects of the suicidal process, thus possibly offering a promising intervention for suicidal ideation. This study aimed at investigating the short-term and long-term effects of FOGT on suicidal thoughts and related variables.

METHODS

A randomized controlled trial was conducted, comparing the intervention group (FOGT + treatment as usual (TAU)) to a control group (TAU) at pre and posttreatment and at a 12-week follow-up. Suicidal ideation was the primary outcome, while depressive symptoms, hopelessness, defeat, entrapment, worrying, and the ability for future-oriented thinking were secondary outcomes.

RESULTS

When compared to the control group, the intervention group showed significant decreases in worrying at posttreatment and significant increases in future-oriented thinking at follow-up. Pre-post analyses within the intervention group showed significant small-to-medium effects for primary as well as most secondary outcomes. Changes in suicidal ideation, depression, hopelessness, and future-oriented thinking remained significant at follow-up.

CONCLUSION

This study provides promising empirical evidence for the use of FOGT for individuals with suicidal ideation.

Suicide Prevention in the European Region

Although the majority of the world's suicides occur in Asia, suicide and self-harm are major concerns in Europe as well. Suicide accounts for 1.4% of the total number of deaths in Europe, with rates highest among those aged over 70 and also high among those aged 45-59 years. Europe accounts for six of the top ten countries with the highest suicide rates internationally. Although rates of suicide attempts and self-harm are not consistently recorded, evidence from hospital-based studies and school-based surveys highlight their extent and scale. Numerous countries in Europe have developed national suicide prevention strategies and action plans. Some of the suicide prevention activities in Belgium, Estonia, Finland, Scotland, France, Germany, Romania, Russia, Sweden, Ukraine, and Italy are summarized. In the chapter we also highlight novel suicide prevention projects funded by the EU which have advanced our understanding of suicide risk and have developed the evidence base for what works to prevent suicide. Examples include the European Alliance Against Depression (EAAD), Saving and Empowering Young Lives in Europe (SEYLE), Suicide Prevention Through Internet and Media Based Mental Health Promotion (SUPREME), and Reduction of Suicides and Trespasses on Railway Property (RESTRAIL). Future challenges and opportunities for suicide prevention in Europe are also discussed.

The online treatment of suicidal ideation: A randomised controlled trial of an unguided web-based intervention

Suicide is a major public health issue, and treatment of suicidal thoughts may contribute to its prevention. Provision of online treatment of suicidal ideation may reduce barriers that suicidal individuals experience in face-to-face treatment. We therefore aimed at evaluating the effectiveness of a web-based intervention targeting a reduction of suicidal ideation. We carried out a two-arm, parallel-design, randomised controlled trial in the general population in Flanders (Belgium) (registered as NCT03209544). Participants who were 18 years or older and experienced suicidal ideation were included. The intervention group (n = 365) received access to the unguided web-based intervention, and the control group (n = 359) was placed on a waitlist. Assessments were carried out at baseline and at 6 and 12 weeks. Participants reported high levels of suicidal ideation, depression, hopelessness, worrying, and anxiety at baseline. Compared to the control group, participants in the intervention group experienced a significant decline in suicidal ideation, depression, hopelessness, worrying, and anxiety both at post-test and at follow-up. An important limitation of the study was a high dropout rate, in particular in the intervention group. Our findings suggest that the online self-help intervention was more effective in reducing suicidal ideation and suicide-related symptoms than a waitlist control in a severely affected population. It can help in filling the gap between crisis help and face-to-face treatment.

The association between motives, perceived problems and current thoughts of self-harm following an episode of self-harm. A network analysis

BACKGROUND

A history of self-harm is a major risk factor for suicide. Some patients are more likely than others to repeat suicidal behaviour after an episode of self-harm. Insight in the relation between current thoughts of self-harm, motives for the self-harm episode and perceived problems may improve prevention strategies. Network analysis allows to investigate the co-occurence of these factors and their association with each other.

METHODS

Ising model based networks are estimated on data collected between 2007-2015 within the Multicentre Study of Self-harm in Flanders. Patients were interviewed within 24 hours after hospitalization by a trained professional on their motives for the episode of self-harm and their perceived problems. Additionally, they were asked whether they had current thoughts of self-harm. Network analyses are used to determine which motives and problems are uniquely related to current thoughts of self-harm, and which are most central in the network.

RESULTS

Data were used of 6068 patients (2279 males and 3789 females). Four internal motives (wish to die, lost control, escape from situation, situation was unbearable), one external motive (show somebody how hopeless I was) and four perceived problems (psychiatric, loneliness, trauma, rejection) are directly related to current thoughts of self-harm. Of all motives and problems, the motive a wish to die is most strongly related to current thoughts of self-harm. However, external motives are more central in the network when compared to internal motives and perceived problems.

LIMITATIONS

Data most probably refer to a selected group of self-harm patients as many individuals who self-harm do not come to the attention of hospital services. Patients might be reluctant to tell professionals they had current thoughts of self-harm.

CONCLUSIONS

Many internal motives and problems are directly related to current thoughts of self-harm, but external motives are more central in the network. The clinically most important motive (wish to die) does not play a central role in the network.

Treatment as usual (TAU) as a control condition in trials of cognitive behavioural-based psychotherapy for self-harm: Impact of content and quality on outcomes in a systematic review

BACKGROUND

Randomized controlled trials (RCTs) are the mainstay of evaluations of the efficacy of psychosocial interventions. In a recent Cochrane systematic review we analysed the efficacy of cognitive behavioural-based psychotherapies compared to treatment as usual (TAU) in adults who self-harm. In this study we examine the content and reporting quality of TAU in these trials and their relationship to outcomes.

METHODS

Five electronic databases (CCDANCTR-Studies and References, CENTRAL, MEDLINE, EMBASE, and PsycINFO) were searched for RCTs, indexed between 1 January 1998 and 30 April 2015, of cognitive-behavioural interventions compared to TAU for adults following a recent (within six months) episode of self-harm. Comparisons were made between outcomes for trials which included different categories of TAU, which were grouped as: multidisciplinary treatment, psychotherapy only, pharmacotherapy only, treatment by primary care physician, minimal contact, or unclear.

RESULTS

18 trials involving 2433 participants were included. The content and reporting quality of TAU varied considerably between trials. The apparent effectiveness of cognitive behavioural psychotherapy varied according to TAU reporting quality and content. Specifically, effects in favour of cognitive-behavioural psychotherapy were strongest in trials in which TAU content was not clearly described (Odds Ratio: 0.29, 95% Confidence Interval 0.15-0.62; three trials) compared to those in which TAU comprised multidisciplinary treatment (Odds Ratio: 0.79, 95% CI 0.63 to 0.97; 12 trials).

LIMITATIONS

The included trials had high risk of bias with respect to participant and clinical personnel blinding, and unclear risk of bias for selective outcome reporting.

CONCLUSIONS

TAU content and quality represents an important source of heterogeneity between trials of psychotherapeutic interventions for prevention of self-harm. Before clinical trials begin, researchers should plan to carefully describe both aspects of TAU to improve the overall quality of investigations.

Interventions for self-harm in children and adolescents

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 SH published in 1998 and 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.

Pharmacological interventions for self-harm in adults

Self-harm (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 self-harm, 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.

Subgenual Anterior Cingulate-Medial Orbitofrontal Functional Connectivity in Medication-Resistant Major Depression: A Neurobiological Marker for Accelerated Intermittent Theta Burst Stimulation Treatment?

BACKGROUND

Accelerated repetitive transcranial magnetic stimulation paradigms have been shown to result in fast decreases in depressive symptoms and suicidal ideation. Although the subgenual anterior cingulate cortex (sgACC) region has been put forward as a possible biological marker, so far, no studies evaluated the clinical effects of accelerated intermittent theta burst stimulation (aiTBS) on sgACC functional connectivity (FC).

METHODS

Fifty patients with treatment-resistant depression were enrolled in this registered randomized double-blind sham-controlled crossover aiTBS treatment study. All received 20 iTBS sessions applied to the left dorsolateral prefrontal cortex (5 daily sessions spread over 4 days). Forty-four complete resting-state functional magnetic resonance imaging scans were collected. Baseline resting-state functional magnetic resonance imaging scans were compared with a matched healthy control group. Besides depression severity, all patients were also assessed with the Scale for Suicide Ideation and the Beck Hopelessness Scale.

RESULTS

Our main resting-state functional magnetic resonance imaging findings indicate that a positive sgACC FC correlation with the medial orbitofrontal cortex could distinguish aiTBS responders from nonresponders at baseline. Beneficial aiTBS treatment strengthened sgACC-medial orbitofrontal cortex FC patterns. Moreover, this increased FC pattern was associated with a decrease in feelings of hopelessness.

CONCLUSIONS

Clinical response to aiTBS treatment is not only characterized by stronger FC patterns between the sgACC and the medial orbitofrontal cortex, but it is also associated with decreases in hopelessness. Our observations provide a possible neurobiological explanation why accelerated repetitive transcranial magnetic stimulation paradigms may result in prompt attenuation of negative thinking in depressed patients.

BackUp: Development and evaluation of a smart-phone application for coping with suicidal crises

Background

Suicide is a major public health issue and has large impact on the lives of many people. Innovative technologies such as smartphones could create new possibilities for suicide prevention, such as helping to overcome the barriers and stigma on help seeking in case of suicidal ideation. Due to their omnipresence, smartphone apps can offer suicide prevention tools very fast, they are easily-accessible, low-threshold and can help overcome some of the help-seeking barriers suicidal people experience. This article describes the development, testing and implementation of a mobile application for coping with suicidal crisis: BackUp.

Methods

Based on the analysis of literature and existing suicide prevention apps several tools were identified as relevant to include in a suicide prevention app. The selected tools (a safety planning tool, a hope box, a coping cards module, and a module to reach out) are evidence based in a face to face context, and could be easily transferred into a mobile app. The testing of existing apps and the literature also revealed important guidelines for the technical development of the application.

Results

BackUp was developed and tested by an expert panel (n = 9) and a panel of end users (n = 21). Both groups rated BackUp as valuable for suicide prevention. Suicidal ideation of the end user group was measured using the Beck Scale for Suicidal Ideation before and after testing BackUp, and showed a small but non-significant decrease. The majority of the testers used BackUp several times. All tools were evaluated as rather or very useable in times of suicidal crisis.

Conclusion

BackUp was positively evaluated and indicates that self-help tools can have a positive impact on suicidal ideation. Apps in particular create opportunities in approaching people that are not reached by traditional interventions; on the other hand they can contribute to suicide prevention in addition to regular care. However, more research is needed on the impact and effect of suicide prevention apps.

Knowledge, Self-Confidence and Attitudes towards Suicidal Patients at Emergency and Psychiatric Departments: A Randomised Controlled Trial of the Effects of an Educational Poster Campaign

Educational posters are used to enhance knowledge, attitudes and self-confidence of patients. Little is known on their effectiveness for educating health care professionals. As these professionals may play an important role in suicide prevention, the effects of a poster and accompanying evaluation and triage guide on knowledge, self-confidence and attitudes regarding suicidal thoughts and behaviours, were studied in a multicentre cluster randomised controlled trial, involving staff from 39 emergency and 38 psychiatric departments throughout Flanders (n = 1171). Structured self-report questionnaires assessed the knowledge, confidence and beliefs regarding suicidal behaviour management, and attitudes. Data were analysed through a Solomon four-group design, with random assignment to the different conditions. Baseline scores for knowledge and provider confidence were high. The poster and accompanying evaluation and triage guide did not have an effect on knowledge about suicide and self-confidence in suicidal behaviour management. However, the poster campaign appeared to be beneficial for attitudes towards suicidal patients, but only among staff from mental health departments that were assigned to the un-pretested condition. Given the limited effects of the poster campaign in the studied population with a relatively high baseline knowledge, the evaluation of this poster as part of a multimodal educational programme in a more heterogeneous sample of health care professionals is recommended.

Decreased resting state metabolic activity in frontopolar and parietal brain regions is associated with suicide plans in depressed individuals

Suicide plans are a major risk factor for suicide, which is a devastating outcome of depression. While structural and functional brain changes have been demonstrated in relation to suicidal thoughts and behaviour, brain mechanisms underlying suicide plans have not yet been studied. Here, we studied changes in regional cerebral metabolic activity in association with suicide plans in depressed individuals. Using ¹⁸FDG-PET, a comparative study of regional cerebral glucose metabolism (rCMRglu) was carried out in depressed individuals with suicidal thoughts and suicide plans, depressed individuals with only suicidal thoughts, depressed individuals without suicide thoughts and plans, and healthy controls. When compared to the other groups, depressed individuals with suicide plans showed relative hypometabolism in the right middle frontal gyrus and the right inferior parietal lobe (Brodmann areas 10 and 39). Suicide plans in depressed individuals appear to be associated with reduced activity in brain areas that are involved in decision-making and choice, more particularly in exploratory behaviour.

Are neurocognitive factors associated with repetition of self-harm? A systematic review

BACKGROUND

Prediction of self-harm is limited clinically. Early identification of individuals likely to repeat self-harm could improve outcomes and reduce suicide risk. Various neurocognitive deficits have been found in people who self-harm, but the ability of these to predict repetition has yet to be established AIMS: Identify neurocognitive factors that may predict repetition of self-harm.

METHODS

Systematic narrative review of English language publications assessing neurocognitive functioning and self-harm repetition, searching multiple databases from inception to March 2015. Quality of studies was appraised. A narrative synthesis was performed.

RESULTS

7026 unique records were identified, and 169 full-texts assessed. 15 unique studies provided data. No imaging studies could be included. Most studies assessed cognitive control or problem solving, but neither factor was consistently associated with repetition. However, specific tasks may show promise. Two studies in adolescents suggest that value-based decision-making impairments could be predictive of repetition. There were too few results for memory to draw specific conclusions.

CONCLUSIONS

Selected studies suggest promise for particular neurocognitive factors and specific cognitive tasks in terms of repetition of self-harm.

Accelerated Intermittent Theta Burst Stimulation for Suicide Risk in Therapy-Resistant Depressed Patients: A Randomized, Sham-Controlled Trial

Objectives: We aimed to examine the effects and safety of accelerated intermittent Theta Burst Stimulation (iTBS) on suicide risk in a group of treatment-resistant unipolar depressed patients, using an extensive suicide assessment scale.

Methods: In 50 therapy-resistant, antidepressant-free depressed patients, an intensive protocol of accelerated iTBS was applied over the left dorsolateral prefrontal cortex (DLPFC) in a randomized, sham-controlled crossover design. Patients received 20 iTBS sessions over 4 days. Suicide risk was assessed using the Beck Scale of Suicide ideation (BSI).

Results: The iTBS protocol was safe and well tolerated. We observed a significant decrease of the BSI score over time, unrelated to active or sham stimulation and unrelated to depression-response. No worsening of suicidal ideation was observed. The effects of accelerated iTBS on mood and depression severity are reported in Duprat et al. (2016). The decrease in suicide risk lasted up to 1 month after baseline, even in depression non-responders.

Conclusions: This accelerated iTBS protocol was safe. The observed significant decrease in suicide risk was unrelated to active or sham stimulation and unrelated to depression response. Further sham-controlled research in suicidal depressed patients is necessary. (Clinicaltrials.gov identifier: NCT01832805).

Accelerated intermittent theta burst stimulation treatment in medication-resistant major depression: A fast road to remission?

Although accelerated repetitive Transcranial Magnetic Stimulation (rTMS) paradigms and intermittent Theta-burst Stimulation (iTBS) may have the potency to result in superior clinical outcomes in Treatment Resistant Depression (TRD), accelerated iTBS treatment has not yet been studied. In this registered randomized double-blind sham-controlled crossover study, spread over four successive days, 50 TRD patients received 20 iTBS sessions applied to the left dorsolateral prefrontal cortex (DLPFC). The accelerated iTBS treatment procedure was found to be safe and resulted in immediate statistically significant decreases in depressive symptoms regardless of order/type of stimulation (real/sham). While only 28% of the patients showed a 50% reduction of their initial Hamilton Depression Rating Scale score at the end of the two-week procedure, this response rate increased to 38% when assessed two weeks after the end of the sham-controlled iTBS protocol, indicating delayed clinical effects. Importantly, 30% of the responders were considered in clinical remission. We found no demographic predictors for response. Our findings indicate that only four days of accelerated iTBS treatment applied to the left DLPFC in TRD may lead to meaningful clinical responses within two weeks post stimulation.

Psychosocial interventions following self-harm in adults: a systematic review and meta-analysis

BACKGROUND

Self-harm (intentional acts of non-fatal self-poisoning or self-injury) is common, particularly in young adults aged 15-35 years, often repeated, and strongly associated with suicide. Effective aftercare of individuals who self-harm is therefore important. We have undertaken a Cochrane systematic review and meta-analysis of the effectiveness of psychosocial interventions for self-harm in adults.

METHODS

We searched five electronic databases (CCDANCTR-Studies and References, CENTRAL, MEDLINE, Embase, and PsycINFO) between Jan 1, 1998, and April 29, 2015, for randomised controlled trials of psychosocial interventions for adults after a recent (within 6 months) episode of self-harm. Most interventions were assessed in single trials. We report results for interventions for which at least three randomised controlled trials comparing interventions with treatment as usual have been published and hence might contribute to clinical guidance. The primary outcome was repetition of self-harm at the conclusion of treatment and at 6, 12, and 24 months' follow-up analysed, when available, with the intention-to-treat method; if this was not possible, we analysed with all available case data.

FINDINGS

We identified 29 non-overlapping randomised controlled trials with three independent trials of the same intervention. Cognitive-behavioural-based psychotherapy (CBT; comprising cognitive-behavioural and problem-solving therapy) was associated with fewer participants repeating self-harm at 6 months' (odds ratio 0·54, 95% CI 0·34-0·85; 12 trials; n=1317) and at 12 months' follow-up (0·80, 0·65-0·98; ten trials; n=2232). There were also significant improvements in the secondary outcomes of depression, hopelessness, suicidal ideation, and problem solving. Patients receiving dialectical behaviour therapy (in three trials) were not less likely to repeat self-harm compared with those provided with treatment as usual at 6 months (odds ratio [OR] 0·59, 95% CI 0·16-2·15; n=267, three trials) or at 12 months (0·36, 0·05-2·47; n=172, two trials). However, the secondary endpoint of frequency of self-harm was associated with a significant reduction with use of dialectical behaviour therapy (mean difference -18·82, 95% CI -36·68 to -0·95). Four trials each of case management (OR 0·78, 95% CI 0·47-1·30; n=1608) and sending regular postcards (OR 0·87, 95% CI 0·62-1·23; n=3277) did not reduce repetition of self-harm.

INTERPRETATION

CBT seems to be effective in patients after self-harm. Dialectical behaviour therapy did not reduce the proportion of patients repeating self-harm but did reduce the frequency of self-harm. However, aside from CBT, there were few trials of other promising interventions, precluding firm conclusions as to their effectiveness.

Suicide prevention strategies revisited: 10-year systematic review

BACKGROUND

Many countries are developing suicide prevention strategies for which up-to-date, high-quality evidence is required. We present updated evidence for the effectiveness of suicide prevention interventions since 2005.

METHODS

We searched PubMed and the Cochrane Library using multiple terms related to suicide prevention for studies published between Jan 1, 2005, and Dec 31, 2014. We assessed seven interventions: public and physician education, media strategies, screening, restricting access to suicide means, treatments, and internet or hotline support. Data were extracted on primary outcomes of interest, namely suicidal behaviour (suicide, attempt, or ideation), and intermediate or secondary outcomes (treatment-seeking, identification of at-risk individuals, antidepressant prescription or use rates, or referrals). 18 suicide prevention experts from 13 European countries reviewed all articles and rated the strength of evidence using the Oxford criteria. Because the heterogeneity of populations and methodology did not permit formal meta-analysis, we present a narrative analysis.

FINDINGS

We identified 1797 studies, including 23 systematic reviews, 12 meta-analyses, 40 randomised controlled trials (RCTs), 67 cohort trials, and 22 ecological or population-based investigations. Evidence for restricting access to lethal means in prevention of suicide has strengthened since 2005, especially with regard to control of analgesics (overall decrease of 43% since 2005) and hot-spots for suicide by jumping (reduction of 86% since 2005, 79% to 91%). School-based awareness programmes have been shown to reduce suicide attempts (odds ratio [OR] 0·45, 95% CI 0·24-0·85; p=0·014) and suicidal ideation (0·5, 0·27-0·92; p=0·025). The anti-suicidal effects of clozapine and lithium have been substantiated, but might be less specific than previously thought. Effective pharmacological and psychological treatments of depression are important in prevention. Insufficient evidence exists to assess the possible benefits for suicide prevention of screening in primary care, in general public education and media guidelines. Other approaches that need further investigation include gatekeeper training, education of physicians, and internet and helpline support. The paucity of RCTs is a major limitation in the evaluation of preventive interventions.

INTERPRETATION

In the quest for effective suicide prevention initiatives, no single strategy clearly stands above the others. Combinations of evidence-based strategies at the individual level and the population level should be assessed with robust research designs.

Increase in Self-Injury as a Method of Self-Harm in Ghent, Belgium: 1987-2013

Background

Self-harm is a major health care problem and changes in its prevalence and characteristics can have important implications for suicide prevention. The objective was to describe trends in the epidemiology of self-harm based on emergency department (A&E departments) visits over a 26-year period in Ghent, Belgium.

Methods

We analyzed data on all self-harm presentations from the three large general hospitals in Ghent between 1987 and 2013. We investigated trends in prevalence (events by year per 100.000), methods and alcohol use.

Results

Rates of self-harm steadily decreased during the 26-year study period. In general female rates of self-harm were higher than male rates. The mean patient age was 35 years. The most commonly used method of self-harm was self-poisoning by means of an overdose of medication (80.8%), followed by cutting (10.2%) and hanging (4.2%). Psychotropics (including antidepressants, benzodiazepines, barbiturates and other tranquilizers) were the most frequently used drugs (74.5%). A proportional increase in the use of self-injurious methods in self-harm was highly significant, more specifically in the use of hanging, jumping from heights and the use of other violent methods such as the use of firearms, jumping before a moving object or other traffic related injury.

Conclusion

This epidemiological study showed an increase in the use of high-lethality methods in self-harm which has important implications for suicide prevention. As restrictions in the availability of these methods are difficult or impossible to achieve, prevention programmes will have to emphasize the role of thorough psychosocial assessment and adequate follow-up care of self-harm patients.

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.

WITHDRAWN: Psychosocial and pharmacological treatments for deliberate self harm

This review has been withdrawn because the topic has been split into three separate reviews, one on psychosocial interventions for self‐harm in adults; another on interventions for self‐harm in children and adolescents; and a third on pharmacological interventions for self‐harm in adults.

The editorial group responsible for this previously published document have withdrawn it from publication.

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.

What is important in being cured from: does discordance between physicians and patients matter? (2)

AIMS

The influence of discordance in what is important in being cured from depression on clinical outcome at 6 months, assessed with a divergence index.

METHODS

304 outpatients treated for depression by general practitioners or by psychiatrists and completing a 6-month treatment period: a divergence index (divergence between physician and patient view on what is important in being cured from depression) was calculated for each physician-patient pair. The relation between this index and outcome at 6 months was analyzed (including depressive, anxious and somatic symptom severity, positive effect, functional impairment and quality of life (psychological and social relations).

RESULTS

Response rates (50% improvement) were 65.9% for depressive symptomatology and 46.2% for anxious symptomatology. The subgroup with a poor physician-patient agreement (highest quartile) on expectations had a worse clinical outcome than the subgroup with an excellent physician-patient agreement (lowest quartile): differences in response rate between these groups ranged from 9% to 27%; this difference reached statistical significance for 3 outcome variables (anxiety, positive effect and social relationships).

CONCLUSIONS

The study shows that outcomes with standard antidepressant drugs are still suboptimal and that discordance between what patients׳ and physicians׳ consider important in the definition of cure from depression significantly influences clinical outcomes at 6 months.

What is important in being cured from depression? Discordance between physicians and patients (1)

AIMS

The comparison of what physicians and patients consider important in being cured from depression.

METHODS

426 outpatients (in primary care and in psychiatric care) with a clinical diagnosis of major depression were included: at the start of antidepressant treatment, the importance of a range of items for being cured from depression (depressive, anxious and somatic symptoms, positive affect, functional impairment, quality of life) was assessed in physicians and patients separately and a ranking was made; after 3 months of treatment, the importance of these items for being cured from depression was re-assessed in the patients.

RESULTS

The items ranked top 10 by physicians mainly contain depressive symptoms while those ranked top 10 by patients mainly contain positive affect items and this attention to positive affect even increases at 3 months follow-up and is higher in patients with recurrent depression than in patients with a first episode of depression. Somatic symptoms consistently get the lowest ranking, as well in physicians as in patients.

CONCLUSIONS

Physicians differ significantly from patients in what they consider important for 'being cured from depression': physicians mainly focus on alleviation of depressive symptoms while patients mainly focus on the restoration of positive affect.

Self-directedness: an indicator for clinical response to the HF-rTMS treatment in refractory melancholic depression

Although well-defined predictors of response are still unclear, clinicians refer a variety of depressed patients for a repetitive Transcranial Magnetic Stimulation (rTMS) treatment. It has been suggested that personality features such as Harm Avoidance (HA) and self-directedness (SD) might provide some guidance for a classical antidepressant treatment outcome. However, to date no such research has been performed in rTMS treatment paradigms. In this open study, we wanted to examine whether these temperament and character scores in particular would predict clinical outcome in refractory unipolar depressed patients when a typical high-frequency (HF)-rTMS treatment protocol is applied. Thirty six unipolar right-handed antidepressant-free treatment resistant depressed (TRD) patients, all of the melancholic subtype, received 10 HF-rTMS sessions applied to the left dorsolateral prefrontal cortex (DLPFC). All patients were classified as at least stage III TRD and were assessed with the Temperament and Character Inventory (TCI) before a HF-rTMS treatment. Only the individual scores on SD predicted clinical outcome. No other personality scales were found to be a predictor of this kind of application. Our results suggest that refractory MDD patients who score higher on the character scale SD may be more responsive to the HF-rTMS treatment.

The role of neuroimaging in our understanding of the suicidal brain

This paper provides a review of the literature on neuroimaging studies of suicidal behaviour, and discusses the relevance of these studies for our understanding of suicidal behaviour. Main findings from molecular imaging studies include a reduced prefrontal perfusion or metabolism and a blunted increase in activation when challenged in association with a history of suicide attempts. Moreover, impairment of the prefrontal serotonergic system in association with suicidal behaviour is demonstrated in a number of studies. Recent structural and functional imaging studies show changes in cortical and subcortical areas and their connections. A number of methodological issues hamper the interpretation of findings. Nevertheless, when findings from studies using divergent techniques are taken together there is increasing evidence of the involvement of a fronto-cingulo-striatal network in suicidal behaviour. This involvement is supported additionally by findings from neuropsychological studies, which demonstrate changes in decision-making processes in association with suicidal behaviour that rely on the same network. Further study is needed to translate the increasing knowledge from neuroimaging studies in clinical tools for the prediction and prevention of suicidal behaviour.

Attempted Suicide in Patients With Eating Disorders

Background: Suicide is a major cause of mortality for patients with eating disorders (ED), especially for patients with anorexia nervosa. Attempted suicide is also relatively common in patients with anorexia or bulimia nervosa. Aims: This study aimed at examining associations between attempted suicide and trait- and state-dependent characteristics in a large clinical population of ED patients. Method: The sample consisted of 1,436 in- and outpatients of the Centre for Eating Disorders of the Ghent University Hospital. Measures of ED symptoms, psychopathology, and personality traits were compared between ED patients with and ED patients without a history of attempted suicide. Results: A history of attempted suicide was found in 11.8% of the ED patients and lifetime suicidal ideation was reported by 43.3%. Multivariate analyses showed that a history of attempted suicide was associated with higher scores on depression, purging symptomatology, early-developed cognitive schemes (impaired autonomy and increased inhibition), and social insecurity. Conclusion: These findings support the increased risk of suicidal behavior in ED. The presence of particular personality traits, of cognitive schemes, and of purging and depressive symptoms should increase vigilance for suicidal behavior.

The acute effects of accelerated repetitive Transcranial Magnetic Stimulation on suicide risk in unipolar depression: preliminary results

BACKGROUND

Suicide is a major health concern. Effective acute interventions are lacking. Recent studies have suggested an acute decrease of suicidal ideations following repetitive Transcranial Magnetic Stimulation (rTMS). However, placebo effects could not be excluded. We aimed to evaluate the acute effect of accelerated intermittent theta burst stimulation (TBS) on suicide risk in depression.

SUBJECTS AND METHODS

In 12 suicidal therapy-resistant depressed patients accelerated intermittent TBS was delivered on the left dorsolateral prefrontal cortex in a randomized, sham-controlled cross-over fashion. Patients received 20 sessions spread over 4 days. The change in severity of suicidal ideation was measured by the Beck Scale of Suicidal Ideation (SSI) before and after treatment.

RESULTS

We found a significant decrease of SSI score over time; unrelated to active or sham stimulation. Furthermore, the attenuation of suicidal thinking was not merely related to depression severity changes caused by TBS.

CONCLUSIONS

Accelerated TBS treatment in depressed suicidal patients was found to be safe and well tolerated and may have the potential to acutely decrease suicidal ideations. However, the efficacy compared to sham has not yet been proven and further sham-controlled research including longer follow-up is needed to substantiate these preliminary findings.

Is there a neuroanatomical basis of the vulnerability to suicidal behavior? A coordinate-based meta-analysis of structural and functional MRI studies

Objective: We conducted meta-analyses of functional and structural neuroimaging studies comparing adolescent and adult individuals with a history of suicidal behavior and a psychiatric disorder to psychiatric controls in order to objectify changes in brain structure and function in association with a vulnerability to suicidal behavior.

Methods: Magnetic resonance imaging studies published up to July 2013 investigating structural or functional brain correlates of suicidal behavior were identified through computerized and manual literature searches. Activation foci from 12 studies encompassing 475 individuals, i.e., 213 suicide attempters and 262 psychiatric controls were subjected to meta-analytical study using anatomic or activation likelihood estimation (ALE).

Result: Activation likelihood estimation revealed structural deficits and functional changes in association with a history of suicidal behavior. Structural findings included reduced volumes of the rectal gyrus, superior temporal gyrus and caudate nucleus. Functional differences between study groups included an increased reactivity of the anterior and posterior cingulate cortices.

Discussion: A history of suicidal behavior appears to be associated with (probably interrelated) structural deficits and functional overactivation in brain areas, which contribute to a decision-making network. The findings suggest that a vulnerability to suicidal behavior can be defined in terms of a reduced motivational control over the intentional behavioral reaction to salient negative stimuli.

The neurobiology of suicide

The stress-diathesis model posits that suicide is the result of an interaction between state-dependent (environmental) stressors and a trait-like diathesis or susceptibility to suicidal behaviour, independent of psychiatric disorders. Findings from post-mortem studies of the brain and from genomic and in-vivo neuroimaging studies indicate a biological basis for this diathesis, indicating the importance of neurobiological screening and interventions, in addition to cognitive and mood interventions, in the prevention of suicide. Early-life adversity and epigenetic mechanisms might explain some of the link between suicide risk and brain circuitry and neurochemistry abnormalities. Results from a range of studies using diverse designs and post-mortem and in-vivo techniques show impairments of the serotonin neurotransmitter system and the hypothalamic-pituitary-adrenal axis stress-response system in the diathesis for suicidal behaviour. These impairments manifest as impaired cognitive control of mood, pessimism, reactive aggressive traits, impaired problem solving, over-reactivity to negative social signs, excessive emotional pain, and suicidal ideation, leading to suicidal behaviour. Biomarkers related to the diathesis might help to inform risk-assessment procedures and treatment choice in the prevention of suicide.

A CBT-Based Psychoeducational Intervention for Suicide Survivors

Background: Bereavement following suicide is associated with an increased vulnerability for depression, complicated grief, suicidal ideation, and suicide. There is, however, a paucity of studies of the effects of interventions in suicide survivors. Aims: This study therefore examined the effects of a cognitive behavioral therapy (CBT)-based psychoeducational intervention on depression, complicated grief, and suicide risk factors in suicide survivors. Method: In total, 83 suicide survivors were randomized to the intervention or the control condition in a cluster randomized controlled trial. Primary outcome measures included maladaptive grief reactions, depression, suicidal ideation, and hopelessness. Secondary outcome measures included grief-related cognitions and coping styles. Results: There was no significant effect of the intervention on the outcome measures. However, the intensity of symptoms of grief, depressive symptoms, and passive coping styles decreased significantly in the intervention group but not in the control group. Conclusion: The CBT-based psychoeducational intervention has no significant effect on the development of complicated grief reactions, depression, and suicide risk factors among suicide survivors. The intervention may, however, serve as supportive counseling for suicide survivors.

Immigration and recommended care after a suicide attempt in Europe: equity or bias?

This report describes the investigation of care recommendations in the medical system across European countries to immigrants who attempted suicide. Data from seven European countries with 8865 local and 2921 immigrant person-cases were derived from the WHO/EURO Multicentre Study on Suicidal Behaviour and ensuing MONSUE (Monitoring Suicidal Behaviour in Europe) project. The relationship between immigrant status and type of aftercare recommended was analysed with binary logistic regression, adjusting for gender, age, method of attempt and the Centre collecting the data. Clear disparities were identified in the care recommendation practices toward immigrants, compared with hosts, over and above differing policies by the European Centres.

Do general practitioners and psychiatrists agree about defining cure from depression? The DEsCRIBE™ survey

BACKGROUND

This study aimed to document the outcome dimensions that physicians see as important in defining cure from depression. The study also aimed to analyse physicians' attitudes about depression and to find out whether they affect their prescribing practices and/or the outcome dimensions that they view as important in defining cure.

METHODS

A 51-item questionnaire based on six validated scales was used to rate the importance of several depression outcome dimensions. Physicians' attitudes about depression were also assessed using the Depression Attitude Scale. Overall, 369 Belgian physicians (264 general practitioners [GPs]; 105 psychiatrists) participated in the DEsCRIBE™ survey.

RESULTS

GPs and psychiatrists strongly agreed that functioning and depressive symptomatology were most important in defining cure; anxious and somatic symptomatology was least important. GPs and psychiatrists differed in their attitudes about depression (p <0.001). Logistic regression revealed that the attitudes of GPs - but not psychiatrists - were significantly associated with their rates of antidepressant prescription (p < 0.001) and that certain attitudes predicted which outcome dimensions were seen as important in defining cure.

CONCLUSIONS

Belgian GPs and psychiatrists strongly agreed on which criteria were important in defining cure from depression but differed in their attitudes about depression. The outcome dimensions that were considered important in defining cure were influenced by physicians' attitudes - this was more pronounced in GPs than in psychiatrists.

The functional neuroanatomy of mental pain in depression

This study aimed at determining the functional neuroanatomy of mental pain, a hitherto neglected symptom in the study of depression, which according to DSM-IV is stronglylinked with suicide. Mental pain (measured with the Orbach & Mikulincer Mental Pain Scale), suicidal ideation (measured using the Hamilton Rating Scale for Depression), hopelessness (measured using Beck's Hopelessness Scale), and regional cerebral blood flow as measured with single photon emission computed tomography were assessed in 39 depressed individuals. Levels of mental pain were significantly and positively associated with suicidal ideation and levels of hopelessness. When compared with patients with low levels of mental pain, those with high levels of mental pain showed relatively increased perfusion in the right dorsolateral prefrontal cortex, occipital cortex and inferior frontal gyrus and in the left inferior temporal gyrus, and relatively decreased perfusion at the medulla. The findings indicate that mental pain in depressed patients is associated with an increased risk of suicide and that high levels of mental pain are associated with changes in perfusion in brain areas that are involved in the regulation of emotions. Further study is warranted to understand whether this association reflects increased emotional processing or decreased cognitive control over mental pain in depressed individuals.

A comparative follow-up study of aftercare and compliance of suicide attempters following standardized psychosocial assessment

This comparative longitudinal study investigated aftercare and compliance of attempted suicide patients after standardized psychosocial assessment. Structured interviews were conducted 1 month (FU1) and 6 months (FU2) after an index suicide attempt. Assessment was associated with more frequent discussion of treatment options with the patient at the hospital and a shorter interval between discharge and contacting the general practitioner (GP). A near significant effect was found for discussing the suicide attempt with the GP more frequently and with start or change of the medication scheme after the index attempt. The current findings support the use of a standardized tool for the assessment of suicide attempters and are in line with the chain of care model for suicide attempters.

Suicide

Suicide receives increasing attention worldwide, with many countries developing national strategies for prevention. Rates of suicide vary greatly between countries, with the greatest burdens in developing countries. Many more men than women die by suicide. Although suicide rates in elderly people have fallen in many countries, those in young people have risen. Rates also vary with ethnic origin, employment status, and occupation. Most people who die by suicide have psychiatric disorders, notably mood, substance-related, anxiety, psychotic, and personality disorders, with comorbidity being common. Previous self-harm is a major risk factor. Suicide is also associated with physical characteristics and disorders and smoking. Family history of suicidal behaviour is important, as are upbringing, exposure to suicidal behaviour by others and in the media, and availability of means. Approaches to suicide prevention include those targeting high-risk groups and population strategies. There are, however, many challenges to large-scale prevention, especially in developing countries.

Sociodemographic and psychopathological risk factors for repetition of attempted suicide: a 5-year follow-up study

The present study examines the association between repetition of suicide attempts and sociodemographic and psychopathological characteristics of patients during a 5-year follow-up period. Participants were 874 suicide attempters referred to the University Hospital of Ghent, among whom 361 (41.3%) patients were available for follow-up analysis. Within 5 years, 29.2% of those admitted for an index suicide attempt repeated non-fatal suicidal behavior. Repetition of suicidal behavior was associated with high scores on measures of psychopathology. In addition, the risk of repetition was increased if the patient was female, aged between 20 and 49, and had a lower education. Multivariate analysis showed significant results for age, the Buglass & Horton Risk of Repetition Scale and for anxiety. Repetition of suicidal behavior is associated with high anxiety, severe depression, more psychiatric symptoms and is increased in young patients.

Deliberate self-harm in adolescents: comparison between those who receive help following self-harm and those who do not

This international comparative study addresses differences between adolescents who engage in deliberate self-harm (DSH) and who receive help following the DSH episode versus those who do not. A standardised self-report questionnaire was completed by pupils aged 14-17 in Australia, Belgium, England, Hungary, Ireland, The Netherlands, and Norway (n=30,532). An act of DSH in the year prior to the study was reported by 1660 participants. Nearly half (48.4%) had not received any help following DSH, 32.8% had received help from their social network only and 18.8% from health services. Except for Hungary, cross-national comparisons revealed remarkably similar findings. Adolescents who had been in contact with health services following DSH reported more often a wish to die, lethal methods, alcohol/drug problems and DSH in the family compared to those who had not. However, those who received no help or help from their social network only were also heavily burdened.

Deliberate self-harm within an international community sample of young people: comparative findings from the Child & Adolescent Self-harm in Europe (CASE) Study

BACKGROUND

Deliberate self-harm among young people is an important focus of policy and practice internationally. Nonetheless, there is little reliable comparative international information on its extent or characteristics. We have conducted a seven-country comparative community study of deliberate self-harm among young people.

METHOD

Over 30,000 mainly 15- and 16-year-olds completed anonymous questionnaires at school in Australia, Belgium, England, Hungary, Ireland, the Netherlands and Norway. Study criteria were developed to identify episodes of self-harm; the prevalence of self-harm acts and thoughts, methods used, repetition, reasons given, premeditation, setting for the act, associations with alcohol and drugs, hospitalisation, and whether other people knew, were examined.

RESULTS

Self-harm was more than twice as common among females as males and, in four of the seven countries, at least one in ten females had harmed herself in the previous year. Additional young people had thought of harming themselves without doing so. More males and females in all countries except Hungary cut themselves than used any other method, most acts took place at home, and alcohol and illegal drugs were not usually involved. The most common reasons given were 'to get relief from a terrible state of mind' followed by 'to die', although there were differences between those cutting themselves and those taking overdoses. About half the young people decided to harm themselves in the hour before doing so, and many did not attend hospital or tell anyone else. Just over half those who had harmed themselves during the previous year reported more than one episode over their lifetime.

CONCLUSIONS

Deliberate self-harm is a widespread yet often hidden problem in adolescents, especially females, which shows both similarities and differences internationally.

Deliberate self-harm in young people: differences in prevalence and risk factors between the Netherlands and Belgium

BACKGROUND

This study aimed to examine prevalence and risk factors of deliberate self-harm in Dutch and Dutch-speaking Belgian adolescents.

METHOD

A cross sectional survey using an anonymous self report questionnaire was performed in both countries. Data on 4,431 Belgian and 4,458 Dutch 15-16 year-old school pupils were analyzed.

RESULTS

Results showed a significant difference between the two countries indicating that lifetime and past year prevalence of deliberate self-harm were both 2.8 times higher in Belgian adolescents than in Dutch adolescents. Further analyses identified differences in the prevalence of factors associated with deliberate self-harm, with Belgian adolescents showing significant higher scores on anxiety, less problem-oriented coping and more common use of alcohol and soft drugs. Belgian adolescents were also at higher risk for the experience of several life events in the previous year and before that such as conflicts with peers, parents and partner, being bullied at school or exposure to suicidal behavior in family and friends. In addition, Belgian adolescents showed less communication with family or teachers about their problems and difficulties.

CONCLUSIONS

The results of the study suggest that the increased risk of deliberate self-harm among Belgian adolescents may be associated with an increased reporting of several important life events and with additional ineffective problem-solving such as less problem-oriented coping, more substance use and less communication about their problems. These results support the assumption that sociocultural aspects of nations can influence the risk of deliberate self-harm and are important to consider when developing prevention strategies.

Cross-national comparisons of the association between alcohol consumption and deliberate self-harm in adolescents

How differences in drinking patterns may affect the impact of alcohol consumption on deliberate self-harm among adolescents is explored in this international comparative study. Schools in Australia, Belgium, England, Hungary, Ireland, the Netherlands, and Norway (N = 30,532) were surveyed. In all countries the risk of deliberate self-harm was significantly elevated among adolescents who reported some or numerous episodes of intoxication, controlling for confounding factors. The results support the assumption that intoxication is significantly related to the association between alcohol consumption and deliberate self-harm in adolescents.

Deliberate self-harm in adolescents

PURPOSE OF REVIEW

To review literature on young people who deliberately harmed themselves that was published between March 2005 and December 2006 in English language journals.

RECENT FINDINGS

Recent follow-up studies have confirmed that deliberate self-harm at a young age is an important indication of mental health problems in later life, including a strongly increased risk of subsequent suicidal behavior. Main recent research includes study of risk factors and predictors of deliberate self-harm, and continuing study of the effects of pharmacological treatment, in particular selective serotonin reuptake inhibitors, in children and adolescents.

SUMMARY

Recent findings regarding risk factors of adolescent deliberate self-harm confirm the importance of depressive disorders, deficient problem solving, exposure to suicidal behavior and familial characteristics. More biological studies of young people are required to provide evidence regarding neurobiological correlates of risk factors of suicidality in young people. The association between the use of antidepressants in depressed children and adolescents and the emergence of suicidal behavior continues to be a matter of debate due to the conflicting evidence from ecological or observational studies and meta-analyses. Although psychotherapeutic approaches have been examined less extensively, the results regarding cognitive behavior therapy in depressed and suicidal young people are clearly positive. Measures to prevent suicidal behavior in young people require further research.
