A multi-method psychological autopsy study on youth suicides in the Netherlands in 2017: Feasibility, main outcomes, and recommendations

The effectiveness and cost-effectiveness of attachment-based family therapy for young adults with high suicidal ideation: protocol of a randomized controlled trial

BACKGROUND

Young adult suicidality is worldwide a prevalent mental health problem and the number one cause of death, with devastating consequences for individuals and their families, and substantial economic costs. However, psychological and pharmacological treatments currently recommended in guidelines for treatment of high-risk youth for fatal suicide have limited effect. In line with the World Health Organization's (WHO) recommendation to involve the family in treatment of these youth, attachment-based family therapy (ABFT) was developed, a 16-week attachment and emotion-focused treatment, implemented in mental health care settings across various European countries in the past years, and becoming increasingly popular among therapists. However, the (cost-)effectiveness of ABFT has not been studied in emerging adults. In the proposed pragmatic randomized controlled trial (RCT), we aim to evaluate the effectiveness and cost-effectiveness of ABFT compared to treatment as usual (TAU) on suicidality, as delivered in daily practice.

METHODS

This pragmatic multicenter study in the Netherlands and Belgium includes 13 participating sites. Participants are suicidal young adults (≥ 31 SIQ-JR score) between 16 and 30 years old who seek mental health treatment (n = 142) and their caregivers. The primary outcome is suicidality (SIQ-JR), with assessments at baseline, post-intervention (5 months after baseline), 3, 6, and 12 months after intervention. We predict that, compared to TAU, ABFT will lead to a stronger reduction in suicidality and will be more cost-effective, over the course of all time points. We also expect stronger decreases in depressive symptoms, given that suicidality is very common in individuals with depressive disorder, as well as more improvement in family functioning, autonomy, entrapment, and young adult attachment, in the ABFT condition.

DISCUSSION

This study can contribute to improving the care for suicidal youngsters with high mortality risk. Treatment of suicidal emerging adults is understudied. The results will inform clinical guidelines and policy makers and improve treatment of suicidal emerging adults.

TRIAL REGISTRATION

This trial is registered on ClinicalTrials.gov (NCT05965622, first posted on July 28, 2023).

The contribution of suicide to maternal mortality: A nationwide population-based cohort study

OBJECTIVE

To identify the incidence and characteristics of maternal suicide.

DESIGN

Nationwide population-based cohort study.

SETTING

The Netherlands, 2006-2020.

POPULATION

Women who died during pregnancy or within 1 year postpartum, and a reference population of women aged 25-45 years.

METHODS

The Cause of Death Register and Medical Birth Register were linked to identify women who died within 1 year postpartum. Data were combined with deaths reported to the Audit Committee for Maternal Mortality and Morbidity (ACMMM), which performs confidential enquiries. Maternal suicides were compared with a previous period (1996-2005). Risk factors were obtained by combining vital statistics databases.

MAIN OUTCOME MEASURES

Comparison of incidence and proportion of maternal suicides among all maternal deaths over time, sociodemographic and patient-related risk factors and underreporting of postpartum suicides.

RESULTS

The maternal suicide rate remained stable with 68 deaths: 2.6 per 100 000 live births in 2006-2020 versus 2.5 per 100 000 in 1996-2005. The proportion of suicides among all maternal deaths increased from 18% to 28%. Most suicides occurred throughout the first year postpartum (64/68); 34 (53%) of the women who died by suicide postpartum were primiparous. Compared with mid-level, low educational level was a risk factor (odds ratio 4.2, 95% confidence interval 2.3-7.9). Of 20 women reported to the ACMMM, 11 (55%) had a psychiatric history and 13 (65%) were in psychiatric treatment at the time of death. Underreporting to ACMMM was 78%.

CONCLUSIONS

Although the overall maternal mortality ratio declined, maternal suicides did not and are now the leading cause of maternal mortality if late deaths up to 1 year postpartum are included. Data collection and analysis of suicides must improve.

Suicide warning signs that are challenging to recognize: a psychological autopsy study of Korean adolescents

BACKGROUND

In South Korea, the leading cause of youth death has been suicide for about 20 years. In this study, we conducted a multi-method psychological autopsy to identify the psychiatric diagnosis, developmental history, personality traits, family history, school life, warning signs of suicide, and risk factors related to suicide for the first time in Korea.

METHODS

This was a postmortem, retrospective, and descriptive study of 36 adolescents who died by suicide between August 2015 and July 2021 in South Korea. We obtained qualitative and quantitative data from the Korean Psychological Autopsy of Adolescent, conducted by the Suicide and School Mental Health Institute, the official student mental health policy-focused research institute of the Korean Ministry of Education.

RESULTS

The adolescents comprised equal percentage of girls and boys. Approximately half of the deaths (55.6%) occurred at home and most (72.2%) involved jumping from a height. Most of the adolescents (97.2%) had one major psychiatric disorder before death, with depressive disorder being the most prevalent (75%). They were at a high risk for internet addiction before death. The most common personality trait was avoidance (28.6%), followed by submissiveness (27.3%). Half of the parents reported that the adolescents were satisfied with their school life and the teachers observed that they had no behavioral problems. One year before death, seven (19.4%) adolescents injured themselves and five (13.9%) had attempted suicide. Most of the deceased (80.6%) had expressed suicide warning signs to their families within one year before death. Adolescents had a long experience of family-related adverse events.

CONCLUSIONS

Most of the adolescents had mental health disorders and expressed suicidal intentions using verbal and nonverbal signs. However, it was challenging for families to recognize the risk signs because of adolescents' personality traits or a good school life. To prevent adolescent suicide, adolescents, parents, and teachers need to be educated to recognize signs of suicide warning signs and equipped to guide adolescents to appropriate care.

Sociodemographic and psychosocial risk factors of railway suicide a mixed-methods study combining data of all suicide decedents in the Netherlands with data from a psychosocial autopsy study

BACKGROUND

Railway suicide has profound implications for the victims and their family, and affects train drivers, railway personnel, emergency services and witnesses. To inform a multilevel prevention strategy, more knowledge is required about psychosocial and precipitating risk factors of railway suicide.

METHODS

Data from Statistics Netherlands of all suicides between 2017 and 2021 (n = 9.241) of whom 986 died by railway suicide and interview data from a psychosocial autopsy of railway suicide decedents (n = 39) were integrated. We performed logistic regression analyses to identify sociodemographic predictors of railway suicide compared to other methods of suicide. The Constant Comparative Method was subsequently employed on interview data from the psychosocial autopsy to identify patterns in psychosocial risk factors for railway suicide.

RESULTS

The strongest predictors of railway suicide compared to other suicide methods were young age (< 30 years old), native Dutch, a high educational level, living in a multi-person household (especially living with parents or in an institution), living in a rural area and a high annual household income of > 150.000 euros. Several subgroups emerged in the psychosocial autopsy interviews, which specifically reflect populations at risk of railway suicide. These subgroups were [1] young adult males with autism spectrum disorder who strived for more autonomy and an independent life, [2] young adult females with persistent suicidal thoughts and behaviours, [3] middle-aged males with a persistent mood disorder who lived with family and who faced stressors proximal to the suicide in personal and professional settings, [4] male out-of-the-blue suicides and [5] persons with psychotic symptoms and a rapid deterioration.

CONCLUSIONS

based on our findings we propose and discuss several recommendations to prevent railway suicide. We must continue to invest in a safe railway environment by training personnel and installing barriers. Additionally, we should adopt prevention strategies that align the needs of subgroups at increased risk, including young females who have attempted other methods of suicide and young males with autism spectrum disorder. Future research should determine the cost-effectiveness and feasibility of low-maintenance, automated interventions near crossings and psychiatric facilities.

Attachment-Based Family Therapy for Adolescents and Young Adults With Suicide Ideation and Depression

Background: Suicide ideation among adolescents is difficult to treat. Attachment-based family therapy (ABFT) is a promising evidence-based family intervention developed to decrease depressive symptoms and suicide ideation among adolescents. Aims: This open trial assessed the feasibility of ABFT for adolescents (12-23 years) with suicide ideation and depression in an outpatient community mental health center in the Netherlands, by monitoring treatment compliance and satisfaction, treatment dose, and symptom reduction. Methods: Eligible patients were referred by the multidisciplinary treatment team at the facility. Treatment dose was monitored by the therapist. Depression (CDI-2), family functioning (SRFF), and strengths and difficulties (SDQ) were assessed online before the intervention and at 3, 6, and 9 months after baseline. Suicide ideation (SIQ-JR) was assessed at each therapy session, and a satisfaction questionnaire was administered postintervention. A total of 25 families signed informed consent, received ABFT treatment, and were included in the analyses. The therapists were at beginners' level of ABFT, working under supervision during the trial. Results: The treatment dose was acceptable, though impacted by COVID-related lockdowns, and treatment compliance was 89%. Patients received on average 22 ABFT sessions, and about half of the patients received additional psychotherapy. On average, patients were satisfied with ABFT. There was a significant decrease in suicide ideation postintervention (d = 0.69) and significant effects on the CDI-2, SRFF, and SDQ at follow-up with medium-to-large effect sizes (d = 0.53-0.94). Limitations: These results should be interpreted with considerable caution, as there was no control group to establish the effectiveness of ABFT, and the sample was small. Conclusion: ABFT appears to be a feasible therapy for youth with depression and suicide ideation in an outpatient community mental health setting.

Guiding principles for the implementation of a standardized psychological autopsy to understand and prevent suicide: a stakeholder analysis

Background

Around 700,000 people die by suicide each year. While the global number of suicides declined over the last decade, the rates remained unchanged in the Netherlands. With this study, we aimed to provide guiding principles for the implementation of a national standardized psychological autopsy to better understand and prevent suicide, by exploring stakeholder perceptions and needs, and barriers to implementation.

Methods

We interviewed 47 representative stakeholders from various fields (e.g., mental healthcare professionals, policy advisors, researchers). A semi structured interview design was used, based on the RE-AIM and Consolidated Framework for Implementation Research (CFIR) theoretical frameworks.

Results

Themes relating to stakeholder perceptions and needs for a standardized psychological autopsy included valorization, accountability, integrability and the needs of the bereaved. Stakeholders believed that participation in a psychological autopsy can help bereaved in their process of grief but noted that evidence to frame the psychological autopsy as postvention is insufficient. The primary focal point should accordingly be to better understand and prevent suicide. Several key limitations of the proposed psychological autopsy approach were detailed, both methodological and implementational.

Conclusion

The stakeholder analysis delineates guiding principles for implementation. Stakeholders believe that a standardized psychological autopsy has merit, provided that key considerations, including valorization and accountability, are integrated in its design. Routine evaluation should be ensured. The findings may guide policy makers and researchers in their endeavors to support a learning, community-based approach for suicide prevention based on a standardized psychological autopsy.

Social media use of adolescents who died by suicide: lessons from a psychological autopsy study

BACKGROUND

while there are many benefits for young people to use social media, adverse effects such as cyberbullying, online challenges, social comparison and imitation may provoke and aggravate suicidal thoughts and behaviors. The influence of social media on mental health and suicidal thoughts and behaviours has been amply studied, but there is little empirical evidence for its potential role in adolescent suicides. The current study aimed to inform digital suicide prevention strategies by examining the meaning of social media in the lives of young suicide victims and elucidating the harmful and supportive effects of social media use on their wellbeing and distress.

METHODS

data were analyzed from a psychological autopsy study of 35 adolescents who died by suicide in the Netherlands (43% of all adolescents who died by suicide in that year). These were 18 girls and 17 boys. All were under the age of twenty years, with an average of seventeen years. Interpretative Phenomenological Analysis was performed of 55 semi structured interviews with peers and parents of the decedents.

RESULTS

young people benefitted from peer support and recovery stories. However, various themes were discussed relating to the harmful effects of social media, including dependency, triggers and imitation, challenges, cybervictimization and psychological entrapment. The themes of dependency and triggers and imitation were more salient in young females. A group of girls cultivated an online identity around their suicidal thoughts and behaviours. Next-of-kin, particularly parents, faced various challenges to talk to the adolescents about social media use, including technological illiteracy, online anonymity, and the youths' closedness.

CONCLUSIONS

based on the findings, we recommend education to stimulate the digital literacy of parents, health workers and educators, supporting conscientious social media use in young people, and extending the prevention of cyberbullying. We encourage future research to examine how virtual social networks may sustain suicidal thoughts and behaviour, and to further investigate the effectiveness of digital interventions, like moderated peer support and the use of positive role models.

Verbal Autopsy as a Tool for Defining Causes of Death in Specific Healthcare Contexts: Study of Applicability through a Traditional Literature Review

Autopsy examination, the gold standard for defining causes of death, is often difficult to apply in certain health care settings, especially in developing countries. The COVID-19 pandemic and its associated difficulties in terms of implementing autopsy examinations have made the need for alternative means of determining causes of death even more evident. One of the most interesting alternatives to the conventional autopsy is the verbal autopsy, a tool that originated in Africa and Asia in the 1950s and consists of a structured interview with the deceased's family members concerning the symptoms manifested by the person and the circumstances of death. In the early 1990s, the first doubts emerged about the validity of verbal autopsies, especially about the real reliability of the cause of death identified through this tool. The objective of the review was to identify studies that had assayed the validity of verbal autopsies through a rigorous comparison of the results that emerged from it with the results of conventional autopsies. When starting from an initial pool of 256 articles, only 2 articles were selected for final review. These are the only two original research articles in which a verbal autopsy validation process was performed by employing the full diagnostic autopsy as the gold standard. The two papers reached opposite conclusions, one suggesting adequate validity of verbal autopsy in defining the cause of death and the other casting serious doubts on the real applicability of this tool. Verbal autopsy undoubtedly has extraordinary potential, especially in the area of health and demographic surveillance, even considering the implementation that could result from the use of artificial intelligence and deep learning. However, at present, there appears to be a lack of solid data to support the robust reliability of this tool in defining causes of death.

The Need for a Data Ecosystem for Youth Mental Health in The Netherlands

The Netherlands is missing nationally representative data on child and adolescent mental health, e.g., on prevalence, course, and consequences of psychological disorders and mental health care utilization. Researchers and policy makers also lack a basic data infrastructure that is necessary to provide timely and reliable data crucial for benchmarking and informed decision making. In this article, we describe the necessity for a clear and well-organized overview of data on youth mental health and mental health care. We look back on three key moments in time to illustrate the breadth of the desire for data. Barriers in collecting structured, national data on a frequent basis are discussed, and several recommendations are provided of what is needed to move towards a data ecosystem that can help us to track the development and mental well-being of all children and youth and the impact of the care they receive.

Development and Validation of the Self-Rating Suicide Risk Screening Questionnaire

Since suicide is one of the major health problems worldwide, the goal of the present study is to develop a psychometrically sound suicide risk screening tool named Suicide Screening Questionnaire- Self-Rating (SSQ-SR) to quantify the risk of suicidal behavior. The development process includes item generation, item revision and refinement, and validation. A total sample of 2,238 adults in South Korea was used for analysis. The results of factor analysis showed that the SSQ-SR, containing 25 items, supported a three-factor model: "Situational factors," "Negative self-perceptions and mental health factors," and "Suicidal thoughts and behaviors." Also, SSQ-SR showed satisfying internal consistency, concurrent validity and discriminant validity. Lastly, the results of ROC analysis showed a cut-off point of 33.5 for the low-risk group and 36.5 for the high-risk group. Considering these results, the current results demonstrate the SSQ-SR is a valid scale and therefore can contribute to future suicide-related studies and prevention.

Characteristics of Korean Children and Adolescents Who Die by Suicide Based on Teachers' Reports

We analyzed the clinical characteristics and suicide-related factors of students who died by suicide in Korea in 2016–2020, based on teachers’ reports. Using data on total suicide deaths (N = 654, mean age = 16.0, 52.6% boys) collected by the Ministry of Education of Korea, we investigated the demographic and clinical characteristics and suicide-related factors of suicide deaths in students aged 9–18 years. Considering gender, more boys (52.6%, N = 344) died by suicide than girls (47.4%, N = 310). About 425 (65.0%) of the suicides were among high school students. The most common suicide method was jumping from a high place (70.6%, N = 454), followed by hanging (25.7%, N = 165). Additionally, 9.4% (N = 48) of the students who died by suicide had a history of attempted suicide, 13.4% (N = 73) had attempted self-harm, and 12.8% (N = 48) were acquainted with someone who had died by suicide. Teachers observed 20.6% (N = 120) of the suicide warning signs at school. Girls tended to have higher rates of attempted suicide, emotional problems, and psychiatric disorders than boys. This study was conducted with the largest sample of Korean suicide students observed at school. Effective suicide-related mental health training for teachers could contribute to suicide prevention in students.

Talking About Sexuality With Youth: A Taboo in Psychiatry?

BACKGROUND

Young people who have psychiatric problems are more likely than their peers to endure difficulties during their sexual and gender identity development.

AIM

This study aims to examine the communication between mental health care providers and their patients about the topics of relations, sexuality and gender identity, including a description of professionals' attitudes toward these topics and the factors that contribute to and inhibit communication.

METHODS

Study participants (n = 242, response rate = 31%) were a representative sample of a large multicenter cohort of 768 mental health care professionals (eg, medical doctors, psychiatrists, psychologists, group counselors, parent counselors) of 7 institutions and 5 solo practices in the Netherlands, who completed a survey on communication about sexuality and gender identity with their young patients (age 12-21 years).

OUTCOMES

Sexuality and gender identity are infrequently discussed by mental health care providers with their young patients or their patients' parents.

RESULTS

Of the study sample, 99.5 % valued sexuality as an important topic to discuss with their patients. However, only 17.1% of the professionals reported that they discussed sexuality-related issues with the majority (>75%) of their patients (adolescents: 19.9%, parents: 14.4%) Additionally, only 2.3 % of the participants discussed gender nonconformity regularly with patients. Information about sexual side effects of prescribed medication was infrequently (20.3%) provided: antidepressants (40.0%), antipsychotics (34.0%), benzodiazepines (5.1%) and stimulants (2.4%). The most frequently cited reasons for not discussing these topics were a lack of awareness, own feelings of discomfort, and the patients' supposed feelings of shame. There was no gender differences observed.

CLINICAL IMPLICATIONS

Recommendations for professionals include to be aware of these topics, initiating age-appropriate conversation and use inclusive language.

STRENGTHS AND LIMITATIONS

The present study included a diverse and representative group of mental health care professionals. Frequency of sexual communication was based on self-report, which brings a risk of bias.

CONCLUSION

Despite a recognized need to engage in age-appropriate communication about sexuality and gender identity in youth mental health care, mental health providers seem to remain hesitant to discuss such topics.

Psychological autopsy study and risk factors for suicide in Muslim countries

BACKGROUND

Suicide and risk factors have been poorly studied in the Muslim-majority countries that hinder the formulation of prevention strategies and affect suicide prevention eventually.

OBJECTIVES

We aimed at identifying and analyzing the psychological autopsy studies assessing the risk factors for suicide conducted in Muslim-majority countries.

METHODS

We did a search to trace all the available psychological autopsy studies in the Muslim countries with the search term "psychological autopsy study in Muslim countries." We also checked the available bibliographies to identify the psychological autopsy studies in the Muslim countries so that all the possible studies could be included.

RESULTS

Out of the Muslim countries, only eight psychological autopsy studies were identified in five countries (Bangladesh [1], Indonesia [1], Iran [1], Pakistan [2], and Turkey [3]). Six studies adopted a case-control study design, and all were carried out in urban settings. The prevalence of psychiatric disorders among case-control studies varied from 52.8% in Turkey to 96% in Pakistan. Psychiatric illness, self-harm, and stressful life events were the commonly replicated risk factors for suicide across studies.

CONCLUSIONS

Psychological autopsy studies have been conducted only in five Muslim countries revealing that the risk factor for suicide is certainly under-researched in the incumbent countries. This review identified a similar list of risk factors for suicide, namely, psychiatric disorder, past non-fatal attempts, and adverse life events compared to the Western countries even though the rate varies.

Can we predict or prevent suicide?: An update

This article updates a 2006 review of empirical data concerning whether clinicians can predict whether patients will die by suicide, or whether fatality can be prevented. Based on further empirical data, a negative conclusion remains justified. There is good evidence that treatment programs, using psychotherapy and medication, can reduce suicide attempts. But people who die by suicide are a distinct population from attempters, and those at high risk do not necessarily present for treatment. Research on suicide prevention has not shown that fatalities among patients can be predicted, or that clinical interventions can reduce the risk. The strongest evidence for prevention derives from reducing access to means. Population-based strategies are more effective than high-risk strategies focusing on patients with suicidal ideas or attempts.

Comparison of Suicide Attempts and Suicide Deaths by Jumping from a High Place in Korean Children and Adolescents

Jumping from a high place is the most common method of suicide among Korean children and adolescents. The aim of this study was to examine the personal, family, and school life of Korean children and adolescents who chose jumping from a high place, among suicide attempts and suicide deaths, based on teachers’ reports. Data on suicide attempts and suicide deaths by jumping from a high place in children and adolescents were collected through the Ministry of Education in South Korea from 2016 to 2018. We compared sociodemographic variables, suicide-related variables, emotional and behavioral status, school life related variables, and variables related to family problems among suicide deaths (n = 262), actual suicide attempts (n = 50), and interrupted or aborted suicide attempts (n = 210). There were differences in educational stage (p < 0.001), place of suicide (p < 0.001), presence of suicide note (p < 0.05) and previous suicide attempt (p < 0.001) among the three groups. The total difficulty score on the Strength Difficulty Questionnaire of interrupted or aborted suicide attempts was higher than that of the other two groups. Our study suggests that the suicide death group tend to present fewer personal and family pathologies and better school adjustment than the suicide attempt group.

Additional Value of Peer Informants in Psychological Autopsy Studies of Youth Suicides

In this study, we examined the feasibility and added value of including peer informants in a psychological autopsy study of youth suicides. Peer semi-structured interview data from 16 cases were analyzed qualitatively and compared to parent data. Results show that peers added information to parents' narratives in general and particularly on social relationships, bullying, school experiences, social media, and family relations. Peers also provided additional information on the presence of certain issues (such as social media contagion) as well as on the emotional impact from certain adverse events that seemed to have functioned as precipitating factors. We conclude that including peers in psychological autopsy studies of youth suicides is feasible and of added value but that more research is desirable. The results initially can be used in the design of psychological autopsies so that the maximum amount of information about each suicide will be learned.

Gender differences in suicide-related communication of young suicide victims

OBJECTIVES

There is limited insight into gender differences in suicide-related communication (SRC) in youths. SRC is defined as "the act of conveying one's own suicide ideation, intent or behaviours to another person". Increasing our understanding of SRC in youths will enable us to recognize and specify needs of female versus male youths. The current study explores SRC in a sample of Dutch suicide victims aged under 20 and examines gender differences.

METHODS

Interview data from a psychological autopsy study of 35 youths who died by suicide in the Netherlands in 2017 were analysed. Qualitative analyses were performed to examine explicit SRC throughout the youths' lives and implicit SRC during the last months prior to suicide. We employed the Constant Comparative Method to explore patterns in the debut, form, frequency, medium, content, type of recipient, and SRC in the last months prior to suicide death.

RESULTS

We identified commonalities in the SRC of youths, including the content of suicide notes and an emphasis on suicide method and preparation in the last months. Girls, however, had an earlier debut of SRC, a higher frequency of explicit SRC, and more often directed SRC towards varied types of recipients compared to boys. Moreover, SRC of girls seemed focused on coping and achieving support from others more than SRC of boys. The SRC of boys in comparison to girls was often ambiguous or diluted by "humorous" connotations.

CONCLUSION

Unique patterns in SRC of boys and girls posed corresponding challenges for next of kin to interpret communications and respond adequately to SRC. The early debut of girls' SRC highlights the importance of early screening and prevention efforts in girls, while the late debut and ambiguity in boys' SRC implores professionals and next of kin to encourage young males to be unequivocal about suicide ideation or intent.

Sociodemographic Differences in Time Trends of Suicidal Thoughts and Suicide Attempts Among Adolescents Living in Amsterdam, The Netherlands

Abstract.Background: Suicidal thoughts and suicide attempts among adolescents are major public health problems. More insight into secular changes in suicidal thoughts and suicide attempts among adolescents from various sociodemographic groups is crucial for adequate and targeted policy-making and prevention. We therefore examined 5-year time trends in suicidal thoughts and suicide attempts among adolescents and potential differences in time trends between sociodemographic groups. Methods: Logistic regression analyses were based on annually repeated cross-sectional data including 26,273 multi-ethnic students (13–14 years old) in the second year of various levels of secondary education in Amsterdam, The Netherlands. Results: Overall, the prevalence of adolescents in Amsterdam with suicidal thoughts decreased from 17.6% during 2010–2011 to 13.2% during 2014–2015. The prevalence of adolescents reporting suicide attempts decreased from 2.9% to 1.9% over the observed 5-year period. We found differences in these time trends between subgroups based on ethnicity and educational level. Limitations: The use of confidential and self-reported data could have biased the results. Conclusion: In order for prevention policy to be effective it is important to pay attention to changes in risk groups for suicidal thoughts and suicide attempts over time.
