Prevalence of attention-deficit hyperactivity disorder in adult prisoners: An updated meta-analysis.

BACKGROUND: Previous meta-analyses may have overestimated the prevalence of attention-deficit hyperactivity disorder (ADHD) in prisoners by including data from selected samples. AIMS: To estimate the prevalence of ADHD in unselected samples of adults in prison and examine potential sources of heterogeneity by meta-regression and subgroup analyses. METHODS: We assessed all studies included in a 2018 systematic review for eligibility and updated the literature search to include studies published up to September 2023. RESULTS: A total of 11 studies reporting robust diagnostic data on ADHD in 3919 unselected adults in prison were included. In meta-regression, ADHD prevalence did not differ between men and women but it was significantly higher in studies using a two-phase design. In random sampling studies, the pooled prevalence of ADHD was 8.3% (95% CI: 3.8-12.8) which was further halved after the removal of an outlier. CONCLUSION: One in 12 adults in prison have been diagnosed with ADHD. Our findings highlight the importance of using clear and consistent inclusion criteria in meta-analyses of prevalence.

Mental and physical health morbidity among people in prisons: an umbrella review.

BACKGROUND: People who experience incarceration are characterised by poor health profiles. Clarification of the disease burden in the prison population can inform service and policy development. We aimed to synthesise and assess the evidence regarding the epidemiology of mental and physical health conditions among people in prisons worldwide. METHODS: In this umbrella review, five bibliographic databases (Web of Science, PubMed, PsycINFO, Embase, and Global Health) were systematically searched from inception to identify meta-analyses published up to Oct 31, 2023, which examined the prevalence or incidence of mental and physical health conditions in general prison populations. We excluded meta-analyses that examined health conditions in selected or clinical prison populations. Prevalence data were extracted from published reports and study authors were contacted for additional information. Estimates were synthesised and stratified by sex, age, and country income level. The robustness of the findings was assessed in terms of heterogeneity, excess significance bias, small-study effects, and review quality. The study protocol was pre-registered with PROSPERO, CRD42023404827. FINDINGS: Our search of the literature yielded 1909 records eligible for screening. 1736 articles were excluded and 173 full-text reports were examined for eligibility. 144 articles were then excluded due to not meeting inclusion criteria, which resulted in 29 meta-analyses eligible for inclusion. 12 of these were further excluded because they examined the same health condition. We included data from 17 meta-analyses published between 2002 and 2023. In adult men and women combined, the 6-month prevalence was 11·4% (95% CI 9·9-12·8) for major depression, 9·8% (6·8-13·2) for post-traumatic stress disorder, and 3·7% (3·2-4·1) for psychotic illness. On arrival to prison, 23·8% (95% CI 21·0-26·7) of people met diagnostic criteria for alcohol use disorder and 38·9% (31·5-46·2) for drug use disorder. Half of those with major depression or psychotic illness had a comorbid substance use disorder. Infectious diseases were also common; 17·7% (95% CI 15·0-20·7) of people were antibody-positive for hepatitis C virus, with lower estimates (ranging between 2·6% and 5·2%) found for hepatitis B virus, HIV, and tuberculosis. Meta-regression analyses indicated significant differences in prevalence by sex and country income level, albeit not consistent across health conditions. The burden of non-communicable chronic diseases was only examined in adults aged 50 years and older. Overall, the quality of the evidence was limited by high heterogeneity and small-study effects. INTERPRETATION: People in prisons have a specific pattern of morbidity that represents an opportunity for public health to address. In particular, integrating prison health within the national public health system, adequately resourcing primary care and mental health services, and improving linkage with post-release health services could affect public health and safety. Population-based longitudinal studies are needed to clarify the extent to which incarceration affects health. FUNDING: Research Foundation-Flanders, Wellcome Trust, National Institutes of Health.

Factors associated with drug use in prison: A systematic review of quantitative and qualitative evidence.

BACKGROUND: About a third of people use drugs during their incarceration, which is associated with multiple adverse health and criminal justice outcomes. Many studies have examined factors associated with in-prison drug use, but this evidence has not yet been systematically reviewed. We aimed to systematically review and synthesise the evidence on factors related to drug use in prison. METHODS: Three databases (PubMed, PsycINFO and Embase) were systematically searched as well as grey literature, for quantitative, qualitative and mixed-methods studies examining factors related to drug use inside prison. We excluded studies that did not explicitly measure in prison drug use or only measured alcohol and/or tobacco use. Study quality was assessed using the Newcastle Ottawa Scale (NOS) for quantitative studies and Critical Appraisal Skills Programme (CASP) for qualitative studies. The review was prospectively registered on PROSPERO (CRD42021295898). RESULTS: Fifty-four studies met the inclusion criteria, reporting data on 26,399 people in prison. Most studies were of low or moderate-quality, and all used self-report to assess drug use. In quantitative studies, studies found that previous criminal justice involvement, poor prison conditions, pre-prison drug use and psychiatric diagnosis were positively associated with drug use in prison. In qualitative studies, reasons for drug use were closely linked to the prison environment lacking purposeful activity and the social context of the prison whereby drug use was seen as acceptable, necessary for cohesion and pressurised. CONCLUSION: In the first systematic review of factors associated with drug use in prison, key modifiable risk factors identified from quantitative and qualitative studies were psychiatric morbidity and poor prison conditions. Non-modifiable factors included previous drug use and criminal history linked to substance use. Our findings indicate an opportunity to intervene and improve the prison environment to reduce drug use and associated adverse outcomes.

An umbrella review of adverse effects associated with antipsychotic medications: the need for complementary study designs.

Antipsychotic medications are widely prescribed in psychotic illnesses and other mental disorders. Effectiveness is well-established, particularly for reducing symptoms such as delusions and hallucinations, but can be impacted by tolerability. Adverse effects are wide-ranging, and vary between antipsychotics, which is clinically important. This umbrella review aimed to comprehensively summarise the extent and quality of evidence for adverse effects associated with antipsychotic use in people with mental disorders. We included 32 meta-analyses of randomised trials and observational studies. The overall robustness of reported associations was considered in terms of review quality, heterogeneity, excess significance bias, and prediction intervals. Using this approach, endocrine and metabolic, movement-related, and sedation and sleep problems were the clinical domains with strongest evidence. The overall quality of included meta-analyses was low, and individual adverse effects were not typically examined in meta-analyses of both randomised trials and observational study designs. Future reviews should focus on adhering to methodological guidelines, consider the complementary strengths of different study designs, and integrate clinically relevant information on absolute rates and severity of adverse effects.

Individual-level risk factors for suicide mortality in the general population: an umbrella review.

BACKGROUND: Deaths by suicide remain a major public health challenge worldwide. Identifying and targeting risk factors for suicide mortality is a potential approach to prevention. We aimed to summarise current knowledge on the range and magnitude of individual-level risk factors for suicide mortality in the general population and evaluate the quality of the evidence. METHODS: In this umbrella review, five bibliographic databases were systematically searched for articles published from database inception to Aug 31, 2022. We included meta-analyses of observational studies on individual-level risk factors for suicide mortality in the general population. Biological, genetic, perinatal, and ecological risk factors were beyond the scope of this study. Effect sizes were synthesised and compared across domains. To test robustness and consistency of the findings, evidence for small-study effects and excess significance bias (ie, the ratio between the overall meta-analysis effect size and that of its largest included study) was examined, and prediction intervals were calculated. Risk of bias was assessed by the Risk of Bias in Systematic Reviews instrument. The protocol was pre-registered with PROSPERO (CRD42021230119). FINDINGS: We identified 33 meta-analyses on 38 risk factors for suicide mortality in the general population. 422 (93%) of the 454 primary studies included in the meta-analyses were from high-income countries. A previous suicide attempt and suicidal ideation emerged as strong risk factors (with effect sizes ranging from 6 to 16). Psychiatric disorders were associated with a greatly elevated risk of suicide mortality, with risk ratios in the range of 4-13. Suicide risk for physical illnesses (such as cancer and epilepsy) and sociodemographic factors (including unemployment and low education) were typically increased two-fold. Contact with the criminal justice system, state care in childhood, access to firearms, and parental death by suicide also increased the risk of suicide mortality. Among risk factors for which sex-stratified analyses were available, associations were generally similar for males and females. However, the quality of the evidence was limited by excess significance and high heterogeneity, and prediction intervals suggested poor replicability for almost two-thirds of identified risk factors. INTERPRETATION: A wide range of risk factors were identified across various domains, which underscores suicide mortality as a multifactorial phenomenon. Prevention strategies that span individual and population approaches should account for the identified factors and their relative strengths. Despite the large number of risk factors investigated, few associations were supported by robust evidence. Evidence of causal inference will need to be tested in high-quality study designs.

Drug use before and during imprisonment: Drivers of continuation.

BACKGROUND: Many people who enter prison have recently used drugs in the community, a substantial portion of whom will continue to do so while incarcerated. To date, little is known about what factors may contribute to the continuation of drug use during imprisonment. METHODS: Self-reported data were collected from a random sample of 1326 adults (123 women) incarcerated across 15 prisons in Belgium. Multivariate regression was used to investigate associations between in-prison drug use and sociodemographic background, criminological profile, drug-related history, and mental health among participants who reported pre-prison drug use. RESULTS: Of all 1326 participants, 719 (54%) used drugs in the 12 months prior to their incarceration and 462 (35%) did so while in prison. There was a strong association between drug use before and during imprisonment (OR = 6.77, 95% CI 5.16-8.89). Of those who recently used drugs in the community, half (52%) continued to do so while incarcerated. Factors independently associated with continuation (versus cessation) were young age, treatment history, polydrug use, and poor mental health. In a secondary analysis, initiation of drug use while in prison was further related to incarceration history and low education. CONCLUSION: Persistence of drug use following prison entry is common. People who continue to use drugs inside prison can be differentiated from those who discontinue in terms of drug-related history and mental health. Routine screening for drug use and psychiatric morbidity on admission to prison would allow for identifying unmet needs and initiating appropriate treatment.

Risk factors for suicide in adults: systematic review and meta-analysis of psychological autopsy studies.

QUESTION: Effective prevention of suicide requires a comprehensive understanding of risk factors. STUDY SELECTION AND ANALYSIS: Five databases were systematically searched to identify psychological autopsy studies (published up to February 2022) that reported on risk factors for suicide mortality among adults in the general population. Effect sizes were pooled as odds ratios (ORs) using random-effects models for each risk factor examined in at least three independent samples. FINDINGS: A total of 37 case-control studies from 23 countries were included, providing data on 40 risk factors in 5633 cases and 7101 controls. The magnitude of effect sizes varied substantially both between and within risk factor domains. Clinical factors had the strongest associations with suicide, including any mental disorder (OR=13.1, 95% CI 9.9 to 17.4) and a history of self-harm (OR=10.1, 95% CI 6.6 to 15.6). By comparison, effect sizes were smaller for other domains relating to sociodemographic status, family history, and adverse life events (OR range 2-5). CONCLUSIONS: A wide range of predisposing and precipitating factors are associated with suicide among adults in the general population, but with clear differences in their relative strength.

Prevalence and risk factors for suicide attempts in prison.

Suicidal behaviour represents a substantial burden of morbidity and mortality in prisons worldwide. We aimed to synthesise the evidence on prevalence and risk factors for suicide attempts during incarceration. In this systematic review and meta-analysis, we searched four bibliographic databases for studies (published up to May 31, 2022) reporting on adults sampled from the general prison population who attempted suicide while incarcerated and an unselected comparison group. A total of 20 studies comprising 19,882 individuals (6.5% women) in 20 countries were eligible for inclusion. The pooled prevalence of suicide attempts during incarceration was 8.6% (95% CI 6.1-11.2) in men and 12.2% (95% CI 7.1-17.2) in women. Across all 36 risk factors studied, the strongest associations were found for suicidal ideation, previous self-harm, and markers of psychiatric morbidity. Prison-related risk factors included solitary confinement, victimisation, and poor social support while incarcerated. Sensitivity analyses indicate that risk factors for near-lethal suicide attempts are similar to those for suicide attempts more generally. In addition to providing a synthesis of previous work, our systematic review highlights several key limitations of the extant literature, which provide directions for future research.

Epidemiology, Risk Factors, and Prevention of Suicidal Thoughts and Behaviour in Prisons: A Literature Review.

Suicide is a global public health concern that affects all echelons of society, albeit not equally so. Compared with adults in the general population, incarcerated offenders are at increased risk to consider, attempt, and die by suicide, which represents a substantial burden of morbidity and mortality in prisons worldwide. This review synthesises recent literature pertaining to the epidemiology, risk factors, and prevention of suicidal thoughts and behaviour among prisoners, and outlines a framework which emphasises the interplay between individuals (importation) and their surroundings (deprivation). The available evidence suggests that prison-specific stressors may exacerbate risk of suicide in an already vulnerable population characterised by complex health and social care needs. Emerging data point to differential mechanisms through which prisoners come to think about suicide and subsequently progress to suicidal behaviour. As risk of suicide is determined by a complex web of synergistically interacting factors, its management and prevention demands a cross-sectoral policy and service response that includes targeted interventions aimed at high-risk prisoners in combination with population strategies that promote the health and wellbeing of all people in prison.

Distinguishing prisoners who think about suicide from those who attempt suicide.

BACKGROUND: Many people who consider suicide do not translate these intentions into action. Although prisoners constitute a particularly high-risk group for suicide, little is known about the factors that distinguish those who think about suicide from those who attempt suicide. METHODS: Participants were 1326 adult offenders (1203 men) randomly selected from 15 Belgian prisons, representing 14% of the national prison population. Multivariate regression analysis compared prisoners who attempted suicide (n = 277) with those who thought about suicide but never made an attempt (n = 312) on a range of established risk factors. RESULTS: Among the 589 participants reporting a lifetime history of suicidal ideation (44% of the total sample), almost half (47%) had made a suicide attempt. Relative to those who only thought about suicide, participants who attempted suicide were more likely to be violent offenders (aOR 2.33, 95% CI 1.49-3.62) and have a history of non-suicidal self-injury (aOR 3.19, 95% CI 2.09-4.86). The presence of self-reported mental disorder diagnosis (aOR = 2.84, 95% CI 1.91-4.24) and illicit substance abuse (aOR = 2.01, 95% CI 1.24-3.28) also independently differentiated prisoners who attempted v. considered suicide. CONCLUSION: This study provides preliminary evidence that behavioural and mental health factors are implicated in the transition from thoughts to acts of suicide in prisoners. Prospective studies are warranted to explore whether these risk factors predict progression from ideation to action over time.

Factors associated with the transition from suicidal ideation to suicide attempt in prison.

BACKGROUND: Although research has identified a wide range of risk factors for suicidal behavior in prisoners, it does not establish who is most likely to act on their suicidal thoughts while incarcerated. METHODS: Self-report data were collected from a random sample of 1,203 adult men incarcerated across 15 prisons in Belgium, who represent 12% of all male prisoners nationwide. RESULTS: One-third (33%) of participants reported having suicidal thoughts during their incarceration, of whom 26% attempted suicide in prison (9% of all prisoners). Factors independently associated with suicide attempt among prisoners with suicidal ideation were violent offending (adjusted odds ratio [aOR] = 2.64, 95% confidence interval [CI] 1.33-5.23), in-prison drug use (aOR = 2.30, 95% CI 1.25-4.22), exposure to suicidal behavior (aOR = 1.96, 95% CI 1.04-3.68), and a lifetime history of nonsuicidal self-injury (aOR = 1.90, 95% CI 1.08-3.36). While related to suicidal thoughts, markers of psychiatric morbidity and aspects of the prison regime were not associated with the progression to suicide attempt. CONCLUSIONS: Many prisoners who think about suicide do not attempt suicide while incarcerated. Factors associated with suicidal ideation are distinct from those that govern the transition to suicidal behavior. Our findings lend support to the hypothesis that behavioral disinhibition might act as a catalyst in the translation of suicidal thoughts into action.

Risk factors for self-harm in prison: a systematic review and meta-analysis.

BACKGROUND: Self-harm is a leading cause of morbidity in prisoners. Although a wide range of risk factors for self-harm in prisoners has been identified, the strength and consistency of effect sizes is uncertain. We aimed to synthesise evidence and assess the risk factors associated with self-harm inside prison. METHODS: In this systematic review and meta-analysis, we searched four electronic databases (PubMed, Embase, Web of Science, and PsycINFO) for observational studies on risk factors for self-harm in prisoners published from database inception to Oct 31, 2019, supplemented through correspondence with authors of studies. We included primary studies involving adults sampled from general prison populations who self-harmed in prison and a comparison group without self-harm in prison. We excluded studies with qualitative or ecological designs, those that reported on lifetime measures of self-harm or on selected samples of prisoners, and those with a comparison group that was not appropriate or not based on general prison populations. Data were extracted from the articles and requested from study authors. Our primary outcome was the risk of self-harm for risk factors in prisoners. We pooled effect sizes as odds ratios (OR) using random effects models for each risk factor examined in at least three distinct samples. We assessed study quality on the basis of the Newcastle-Ottawa Scale and examined between-study heterogeneity. The study protocol was registered with PROSPERO, CRD42018087915. FINDINGS: We identified 35 independent studies from 20 countries comprising a total of 663 735 prisoners, of whom 24 978 (3·8%) had self-harmed in prison. Across the 40 risk factors examined, the strongest associations with self-harm in prison were found for suicide-related antecedents, including current or recent suicidal ideation (OR 13·8, 95% CI 8·6-22·1; I2=49%), lifetime history of suicidal ideation (8·9, 6·1-13·0; I2=56%), and previous self-harm (6·6, 5·3-8·3; I2=55%). Any current psychiatric diagnosis was also strongly associated with self-harm (8·1, 7·0-9·4; I2=0%), particularly major depression (9·3, 2·9-29·5; I2=91%) and borderline personality disorder (9·2, 3·7-22·5; I2=81%). Prison-specific environmental risk factors for self-harm included solitary confinement (5·6, 2·7-11·6; I2=98%), disciplinary infractions (3·5, 1·2-9·7; I2=99%), and experiencing sexual or physical victimisation while in prison (3·2, 2·1-4·8; I2=44%). Sociodemographic (OR range 1·5-2·5) and criminological (1·8-2·3) factors were only modestly associated with self-harm in prison. We did not find clear evidence of publication bias. INTERPRETATION: The wide range of risk factors across clinical and custody-related domains underscores the need for a comprehensive, prison-wide approach towards preventing self-harm in prison. This approach should incorporate both population and targeted strategies, with multiagency collaboration between the services for mental health, social care, and criminal justice having a key role.

What Differentiates Prisoners Who Attempt Suicide from Those Who Experience Suicidal Ideation? A Nationally Representative Study.

OBJECTIVE: Many people who think about suicide do not engage in suicidal behavior. Identifying risk factors implicated in the process of behavioral enaction is crucial for suicide prevention, particularly in high-risk groups such as prisoners. METHOD: Cross-sectional data were drawn from a nationally representative sample of 17,891 prisoners (79% men) in the United States. We compared prisoners who attempted suicide (attempters; n = 2,496) with those who thought about suicide but never made an attempt (ideators; n = 1,716) on a range of established risk factors. RESULTS: More than half (59%) of participants who experienced suicidal ideation had also attempted suicide. Violent offending, trauma, brain injury, alcohol abuse, and certain mental disorders distinguished attempters from ideators. CONCLUSION: Our results fit within recent ideation-to-action theories that emphasize the role of a capability for suicide in the transition from thoughts to acts of suicide.

Mental disorders and risk of suicide attempt in prisoners.

BACKGROUND: Mental disorders are overrepresented in prisoners, placing them at an increased risk of suicide. Advancing our understanding of how different mental disorders relate to distinct stages of the suicidal process-the transition from ideation to action-would provide valuable information for clinical risk assessment in this high-risk population. METHODS: Data were drawn from a representative sample of 1212 adults (1093 men) incarcerated across 13 New Zealand prisons, accounting for 14% of the national prison population. Guided by an ideation-to-action framework, three mutually exclusive groups of participants were compared on the presence of mental disorders assessed by validated DSM-IV diagnostic criteria: prisoners without any suicidal history (controls; n = 778), prisoners who thought about suicide but never made a suicide attempt (ideators; n = 187), and prisoners who experienced suicidal ideation and acted on such thoughts (attempters; n = 247). RESULTS: One-third (34.6%) of participants reported a lifetime history of suicidal ideation, of whom 55.6% attempted suicide at some point (19.2% of all prisoners). Suicidal outcomes in the absence of mental disorders were rare. Whilst each disorder increased the odds of suicidal ideation (OR range 1.73-4.13) and suicide attempt (OR range 1.82-4.05) in the total sample (n = 1212), only a select subset of disorders was associated with suicide attempt among those with suicidal ideation (n = 434). Drug dependence (OR 1.65, 95% CI 1.10-2.48), alcohol dependence (OR 1.89, 95% CI 1.26-2.85), and posttraumatic stress disorder (OR 2.09, 95% CI 1.37-3.17) distinguished attempters from ideators. CONCLUSION: Consistent with many epidemiological studies in the general population, our data suggest that most mental disorders are best conceptualized as risk factors for suicidal ideation rather than for suicide attempt. Once prisoners consider suicide, other biopsychosocial factors beyond the mere presence of mental disorders may account for the progression from thoughts to acts of suicide.

How to overcome political and legal barriers to the implementation of a drug consumption room: an application of the policy agenda framework to the Belgian situation.

BACKGROUND: For more than 30 years, drug consumption rooms (DCRs) have been implemented in Western countries. DCRs are supported by a large body of evidence about public safety and public health effectiveness. However, a political consensus has never been achieved in Belgium on amending the existing law that explicitly penalises the supply of a room for facilitating drug use. Despite this adverse legal and policy framework, a DCR opened in the city of Liège in 2018. In this case report, we applied the theoretical framework proposed by Shiffman and Smith for policy agenda setting, in order to describe and assess how political and legal barriers were overcome in the process of opening the DCR. CASE PRESENTATION: For some years, fieldworkers and some city policymakers argued for DCR implementation in Belgium, but without gaining the support of the national authorities, mainly for ideological reasons. In order to address this debate, a feasibility study of DCR implementation in Belgian cities was commissioned. At the national level, an institutional debate took place about the political responsibility for DCRs as a public health intervention, as health care is mainly a matter of regional policy. The lack of consensus led to a situation of political deadlock. Meanwhile, the publication of the study report and the context of local elections offered an opportunity for Liège authorities to reignite the local debate on DCRs. At the local level, law enforcement, care professionals, residents, users, and the press were all involved in the implementation process. Therefore, a local consensus was formed and despite the absence of any national legal change, the DCR opened 1 month before the local elections. It has been working without major medical or legal incident since then. Incidentally, the mayor of Liège was re-elected. CONCLUSIONS: Although the lack of a legal framework may engender instability and affect longer-term effectiveness, the DCR implementation in Liège was successful and was based on a local consensus and effective communication rather than on an appropriate legal framework. The experience provides lessons for other cities that are considering opening a DCR despite an adverse legal and political context.

Non-suicidal self-injury and co-occurring suicide attempt in male prisoners.

High rates of non-suicidal self-injury (NSSI) and suicide attempts (SA) are well documented in prisoners, however, few studies examined their co-occurrence in this high-risk population. Study participants were 1203 adult men randomly selected from 15 Belgian prisons, representing 12% of the national male prison population. Lifetime prevalence rates for NSSI and SA are 17% and 20% respectively, with half (55%) of self-injurers reporting a SA history. Bivariate analyses show that NSSI and SA are significantly related to one another, and many risk factors are common to both. Multivariate analysis comparing prisoners who engaged in NSSI with (n = 109) and without (n = 90) co-occurring SA indicates that suicidal ideation is the strongest independent correlate of SA among self-injurers. Additionally, relative to those with a history of NSSI only, prisoners with co-occurring NSSI and SA are significantly more likely to be violent offenders, being prescribed psychotropic medication, and report a psychiatric diagnosis; suggesting that they constitute a more clinically severe subgroup. Collectively, these findings highlight the marked overlap between NSSI and SA in prisoners, both in terms of prevalence and correlates, with suicidal ideation being an important predictor of suicide risk among self-injurers.

A 17-Year National Study of Prison Suicides in Belgium.

BACKGROUND: Suicide is a leading cause of mortality in prisoners worldwide, yet empirical data on this matter are lacking in Belgium. AIMS: This study sought to describe characteristics associated with a consecutive series of suicides in Belgian prisons from 2000 to 2016 inclusive, in order to inform suicide prevention strategies. METHOD: All documented cases of suicide ( N = 262) were reviewed using a standardized assessment checklist. Official records were abstracted for prisoners' sociodemographic, criminological, and clinical information, as well as for suicide-related characteristics. RESULTS: Over the 17-year study period, suicides accounted for one third of all deaths in Belgian prisons. The average annual suicide rate in Belgium from 2000 to 2016 was 156.2 per 100,000 prisoners. Examination of all cases highlights both individual (psychiatric disorders and a history of suicide attempt) and situational (the early period of incarceration, interfacility transfers, and placement in solitary confinement) factors common in many prison suicides; some of them amenable to (clinical) management, which presents several potential avenues for suicide prevention. LIMITATIONS: Given the absence of a matched control group, no conclusions could be ascertained regarding risk factors. CONCLUSION: Suicide is a common, preventable cause of death among prisoners in Belgium. The results underscore the timely need for national standards and guidelines for suicide prevention in Belgian prisons.

Suicidal ideation while incarcerated: Prevalence and correlates in a large sample of male prisoners in Flanders, Belgium.

Prisoners constitute a high-risk group for suicide. As an early stage in the pathway leading to suicide, suicidal ideation represents an important target for prevention, yet research on this topic is scarce in general prison populations. Using a cross-sectional survey design, correlates of suicidal ideation while incarcerated were examined in a sample of 1203 male prisoners, randomly selected from 15 Flemish prisons. Overall, a lifetime history of suicidal ideation and attempts was endorsed by 43.1% and 20.3% of respondents, respectively. Approximately a quarter of all prisoners (23.7%) reported past-year suicidal ideation during their current incarceration, which was significantly associated with both imported vulnerabilities (psychiatric diagnoses and a history of attempted suicide) and variables unique to the prison experience (lack of working activity, exposure to suicidal behaviour by peers, and low levels of perceived autonomy, safety and social support) in the multivariate regression analysis. A first-ever period of imprisonment and a shorter length of incarceration (≤12months) were also associated with increased odds of recent suicidal ideation. Collectively, the current findings underscore the importance of both vulnerability factors and prison-specific stressors for suicidal ideation in prisoners, and hence the need for a multi-faceted approach to suicide prevention in custodial settings. In addition to the provision of appropriate mental health care, environmental interventions that target modifiable aspects of the prison regime could provide a substantial buffer for the onset and persistence of suicidal ideation in this at-risk population.

Shifting attention between the space of the body and external space: electrophysiological correlates of visual-nociceptive crossmodal spatial attention.

The study tested whether nociceptive stimuli applied to a body limb can orient spatial attention in external space toward visual stimuli delivered close to that limb. Nociceptive stimuli were applied to either the left or the right hand. Task-relevant visual stimuli were delivered at the location adjacent to the stimulated hand (70% valid trials) or adjacent to the other hand (30% invalid trials). Visual stimuli were discriminated with shorter reaction times and elicited ERPs of greater magnitude in the valid as compared to the invalid trials. This enhancement affected the N1 component, suggesting that the location of the nociceptive cue modifies visual processing through a modulation of neural activity in the visual cortex. We hypothesize the existence of a common frame of reference able to coordinate the mapping of the space of the body and the mapping of the external space.
