Age, period, and cohort patterns in the epidemiology of suicide attempts among sexual minorities in the United States and Canada: detection of a second peak in middle adulthood.

PURPOSE: Sexual minority adults experience fivefold greater risk of suicide attempt, as compared with heterosexuals. Establishing age-specific epidemiological patterns of suicide is a prerequisite to planning interventions to redress the sexual orientation suicide inequity, and such patterns must be carefully interpreted in light of correlated period and cohort effects. We, therefore, combined US and Canadian data (1985-2017) from primary (two pooled multi-year national surveys, N = 15,477 and N = 126,463) and secondary (published, meta-analytic, N = 122,966) sources to separately estimate age, period, and cohort trends in self-reported suicide attempts among sexual minorities. METHODS: Age- and gender-stratified cross-sectional data were used to infer age and cohort effects. Age-collapsed meta-analyzed data were used to infer period effects among sexual minorities of all genders. RESULTS: We identified a bimodal age distribution in recent suicide attempts for sexual minorities across genders, though more pronounced among sexual minority men: one peak in adolescence (18-20 years of age for both genders) and one peak nearing mid-life (30-35 years of age for men; 35-40 years of age for women). This pattern was also apparent using recall data within birth cohorts of sexual minority men, suggesting it is not an artifact of birth cohort effects. Finally, we observed decreasing trends in lifetime suicide attempt prevalence estimates for both sexual minorities and heterosexuals, though these decreases did not affect the magnitude of the sexual orientation disparity. CONCLUSION: In the context of exclusively adolescent-focused suicide prevention interventions for sexual minorities, tailored suicide prevention for sexual minority adults should be pursued throughout the life course.

Prevalence and Correlates of Youth Suicidal Ideation and Attempts: Evidence from the 2014 Ontario Child Health Study.

OBJECTIVES: To present the 12-month prevalence and correlates of suicidal ideation and attempts in a sample of youth in Ontario. METHODS: Data come from the 2014 Ontario Child Health Study, a provincially representative survey of families with children in Ontario. Youth aged 14 to 17 y ( n = 2,396) completed a computer-assisted, self-administered questionnaire in their home to assess the occurrence of suicidal ideation, suicidal attempts, and associated correlates, including non-suicidal self-injury, mental disorders, substance use, peer victimization and exposure to child maltreatment. Socio-demographic information was collected from the parent. Logistic regression models were used to identify correlates that distinguished between youth reporting: 1) no suicidal ideation or attempts, 2) suicidal ideation but no attempts, and 3) suicidal ideation and attempts. RESULTS: The 12-month prevalence of suicidal ideation and attempts was 8.1% and 4.3%, respectively. All clinical and behavioural correlates were significantly higher among youth reporting suicidal ideation or attempts, as compared with non-suicidal youth. In adjusted models, depression and non-suicidal self-injury were each independently associated with elevated odds of suicidal ideation (OR = 4.84 and 4.19, respectively) and suicidal attempt (OR = 7.84 and 22.72, respectively). Among youth who reported suicidal ideation, the only variable that differentiated youth who attempted suicide v. those who did not, in adjusted models, was non-suicidal self-injury (OR = 3.89). CONCLUSIONS: Suicidal ideation and attempts are common among youth in Ontario, often co-occurring with mental disorders and high-risk behaviours. These findings underscore the need for effective prevention and intervention strategies, particularly for youth depression and non-suicidal self-injury.

Emergency Department Presentations and Youth Suicide: A Case-Control Study.

OBJECTIVE: We estimate associations between emergency department (ED) diagnoses and suicide among youth to guide ED care. METHOD: This ED-based case-control study used data from the Office of the Chief Coroner and all EDs in Ontario, Canada. Cases ( n = 697 males and n = 327 females) were aged 10 to 25 years who died by suicide in Ontario between April 2003 and March 2014, with an ED contact in the year before their death. Same-aged ED-based controls were selected during this time frame. Crude and adjusted odds ratios (aORs) and 95% confidence intervals were calculated. RESULTS: Among youth diagnosed with a mental health problem at their most recent ED contact (41.9% cases, 5% controls), suicide was elevated among nonfatal self-inflicted: 'other' injuries, including hanging, strangulation, and suffocation in both sexes (aORs > 14); cut/pierce injuries in males (aOR > 5); poisonings in both sexes (aORs > 2.2); and mood and psychotic disorders in males (aORs > 1.7). Among those remaining, 'undetermined' injuries and poisonings in both sexes (aORs > 5), 'unintentional' poisonings in males (aOR = 2.1), and assault in both sexes (aORs > 1.8) were significant. At least half of cases had ED contact within 106 days. CONCLUSIONS: The results highlight the need for timely identification and treatment of mental health problems. Among those with an identified mental health problem, important targets for suicide prevention efforts are youth with self-harm and males with mood and psychotic disorders. Among others, youth with unintentional poisonings, undetermined events, and assaults should raise concern.

Evidence of Multiple Mediating Pathways in Associations Between Constructs of Stigma and Self-Reported Suicide Attempts in a Cross-Sectional Study of Gay and Bisexual Men.

Gay and bisexual men (GBM) are more likely to attempt suicide than heterosexual men. This disparity is commonly interpreted using minority stress theory; however, specific pathways from antigay stigma to suicidal behavior are poorly understood. We aimed to estimate associations between multiple constructs of stigma and suicide attempts among adult GBM, and to measure the proportion of these associations mediated by distinct suicide risk factors, thus identifying proximal points of intervention. Data were drawn from a Canadian community-based survey of adult GBM. Structural equation modeling was used to compare associations between three latent constructs-enacted stigma (e.g., discrimination, harassment), anticipated prejudice (worry about encountering antigay/bisexual prejudice), and sexuality concealment-and self-reported suicide attempts (last 12 months). Coefficients were estimated for direct, indirect, and total pathways and evaluated based on magnitude and statistical significance. The proportion of associations mediated by depression, drug/alcohol use, and social isolation was calculated using indirect paths. Among 7872 respondents, 3.4% reported a suicide attempt in the past 12 months. The largest total association was observed for enacted stigma, and this association was partially mediated by depression and drug/alcohol use. The total association of anticipated prejudice was relatively smaller and mediated by depression and social isolation. Concealment had an inverse association with suicide attempts as mediated by depression but was also positively associated with suicide attempts when mediated through social isolation. Multiple constructs of antigay stigma were associated with suicide attempts; however, mediating pathways differed by construct, suggesting that a combination of strategies is required to prevent suicide in adult GBM.

Les soins médicaux de jeunes hommes et de jeunes femmes qui décèdent par suicide.

OBJECTIVE: Prior year medical care was compared among youth dying by suicide to their peers. Effect modification of these associations by age or place of residency (rural versus larger community sizes) was examined in a large, medically insured population. METHOD: This population-based case control study used data from the Office of the Chief Coroner in Ontario, Canada, linked to health care administrative data to examine associations between medical care for mental health or other reasons (versus no medical care) and suicide. Decedents ( n = 1203 males and n = 454 females) were youth (aged 10 to 25 years) who died by suicide in Ontario between April 2003 and March 2014, inclusive. Peers of the same ages were frequency matched to decedents on sex and place of residency. Logistic regression was used to calculate odds ratios and 95% confidence intervals and to test effect modification. RESULTS: Associations with mental health care were stronger in decedents than peers with a gradation of care (i.e., outpatient only, emergency department [ED], inpatient care) in both sexes. However, these associations were weaker among youth living in rural communities. Furthermore, older males (aged 18 to 25 years) were less likely than younger males (aged 10 to 17 years) to access the ED (ambulatory care only). This decrease was observed in rural and larger communities alongside no increase in medical care for other reasons. CONCLUSIONS: Geographical and age-related barriers to mental health care exist for youth who die by suicide. Preventive efforts can address these barriers, intervening early and integrating services, including the ED.

Perinatal suicide in Ontario, Canada: a 15-year population-based study.

BACKGROUND: Death by suicide during the perinatal period has been understudied in Canada. We examined the epidemiology of and health service use related to suicides during pregnancy and the first postpartum year. METHODS: In this retrospective, population-based cohort study, we linked health administrative databases with coroner death records (1994-2008) for Ontario, Canada. We compared sociodemographic characteristics, clinical features and health service use in the 30 days and 1 year before death between women who died by suicide perinatally, women who died by suicide outside of the perinatal period and living perinatal women. RESULTS: The perinatal suicide rate was 2.58 per 100 000 live births, with suicide accounting for 51 (5.3%) of 966 perinatal deaths. Most suicides occurred during the final quarter of the first postpartum year, with highest rates in rural and remote regions. Perinatal women were more likely to die from hanging (33.3% [17/51]) or jumping or falling (19.6% [10/51]) than women who died by suicide non-perinatally (p = 0.04). Only 39.2% (20/51) had mental health contact within the 30 days before death, similar to the rate among those who died by suicide non-perinatally (47.7% [762/1597]; odds ratio [OR] 0.71, 95% confidence interval [CI] 0.40-1.25). Compared with living perinatal women matched by pregnancy or postpartum status at date of suicide, perinatal women who died by suicide had similar likelihood of non-mental health primary care and obstetric care before the index date but had a lower likelihood of pediatric contact (64.5% [20/31] v. 88.4% [137/155] at 30 days; OR 0.24, 95% CI 0.10-0.58). INTERPRETATION: The perinatal suicide rate for Ontario during the period 1994-2008 was comparable to international estimates and represents a substantial component of Canadian perinatal mortality. Given that deaths by suicide occur throughout the perinatal period, all health care providers must be collectively vigilant in assessing risk.

Suicidal Behaviour Among Adolescents and Young Adults with Self-Reported Chronic Illness.

OBJECTIVE: The aims of this study were to estimate the: (1) 12-mo prevalence of suicidal thoughts, plans, and attempts in a population sample of adolescents and young adults with and without chronic illness; (2) associations among chronic illness and suicidal thoughts and behaviour (STB); and, (3) moderating roles of mood and substance use disorder on this association. METHOD: Individuals were aged 15 to 30 y ( n = 5,248) from the Canadian Community Health Survey-Mental Health. Twelve-month STB and psychiatric disorder were measured using the World Health Organization Composite International Diagnostic Interview 3.0. Multinomial logistic regression examined associations between chronic illness and STB, adjusting for relevant sociodemographic and health characteristics. Product term interactions among chronic illness, mood, and substance use disorders were included in the regression models to examine potential moderating effects. RESULTS: Prevalence of suicidal thoughts, plans, and attempts was higher in individuals with chronic illness ( P < 0.01 for all). After adjustment, chronic illness increased the odds for suicidal thoughts [OR = 1.28 (1.01 to 1.64)], plans [OR = 2.34 (1.22 to 4.39)], and attempts [OR = 4.63 (1.52 to 14.34)]. In the presence v. absence of a mood disorder, the odds for suicidal thoughts were higher among individuals with chronic illness [OR = 1.89 (1.06 to 5.28)]. CONCLUSIONS: Suicidal thoughts and behaviours are common among adolescents and young adults with chronic illness, particularly among those with comorbid mood disorders. Health professionals should routinely ask about STB during assessments of their adolescent and young adult patients.

Lifetime Prevalence of Suicide Attempts Among Sexual Minority Adults by Study Sampling Strategies: A Systematic Review and Meta-Analysis.

BACKGROUND: Previous reviews have demonstrated a higher risk of suicide attempts for lesbian, gay, and bisexual (LGB) persons (sexual minorities), compared with heterosexual groups, but these were restricted to general population studies, thereby excluding individuals sampled through LGB community venues. Each sampling strategy, however, has particular methodological strengths and limitations. For instance, general population probability studies have defined sampling frames but are prone to information bias associated with underreporting of LGB identities. By contrast, LGB community surveys may support disclosure of sexuality but overrepresent individuals with strong LGB community attachment. OBJECTIVES: To reassess the burden of suicide-related behavior among LGB adults, directly comparing estimates derived from population- versus LGB community-based samples. SEARCH METHODS: In 2014, we searched MEDLINE, EMBASE, PsycInfo, CINAHL, and Scopus databases for articles addressing suicide-related behavior (ideation, attempts) among sexual minorities. SELECTION CRITERIA: We selected quantitative studies of sexual minority adults conducted in nonclinical settings in the United States, Canada, Europe, Australia, and New Zealand. DATA COLLECTION AND ANALYSIS: Random effects meta-analysis and meta-regression assessed for a difference in prevalence of suicide-related behavior by sample type, adjusted for study or sample-level variables, including context (year, country), methods (medium, response rate), and subgroup characteristics (age, gender, sexual minority construct). We examined residual heterogeneity by using τ(2). MAIN RESULTS: We pooled 30 cross-sectional studies, including 21,201 sexual minority adults, generating the following lifetime prevalence estimates of suicide attempts: 4% (95% confidence interval [CI] = 3%, 5%) for heterosexual respondents to population surveys, 11% (95% CI = 8%, 15%) for LGB respondents to population surveys, and 20% (95% CI = 18%, 22%) for LGB respondents to community surveys (Figure 1). The difference in LGB estimates by sample type persisted after we accounted for covariates with meta-regression. Sample type explained 33% of the between-study variability. AUTHOR'S CONCLUSIONS: Regardless of sample type examined, sexual minorities had a higher lifetime prevalence of suicide attempts than heterosexual persons; however, the magnitude of this disparity was contingent upon sample type. Community-based surveys of LGB people suggest that 20% of sexual minority adults have attempted suicide. PUBLIC HEALTH IMPLICATIONS: Accurate estimates of sexual minority health disparities are necessary for public health monitoring and research. Most data describing these disparities are derived from 2 sample types, which yield different estimates of the lifetime prevalence of suicide attempts. Additional studies should explore the differential effects of selection and information biases on the 2 predominant sampling approaches used to understand sexual minority health.

A Youth Suicide Prevention Plan for Canada: A Systematic Review of Reviews.

OBJECTIVE: We conducted an expedited knowledge synthesis (EKS) to facilitate evidence-informed decision making concerning youth suicide prevention, specifically school-based strategies and nonschool-based interventions designed to prevent repeat attempts. METHODS: Systematic review of review methods were applied. Inclusion criteria were as follows: systematic review or meta-analysis; prevention in youth 0 to 24 years; peer-reviewed English literature. Review quality was determined with AMSTAR (a measurement tool to assess systematic reviews). Nominal group methods quantified consensus on recommendations derived from the findings. RESULTS: No included review addressing school-based prevention (n = 7) reported decreased suicide death rates based on randomized controlled trials (RCTs) or controlled cohort studies (CCSs), but reduced suicide attempts, suicidal ideation, and proxy measures of suicide risk were reported (based on RCTs and CCSs). Included reviews addressing prevention of repeat suicide attempts (n = 14) found the following: emergency department transition programs may reduce suicide deaths, hospitalizations, and treatment nonadherence (based on RCTs and CCSs); training primary care providers in depression treatment may reduce repeated attempts (based on one RCT); antidepressants may increase short-term suicide risk in some patients (based on RCTs and meta-analyses); this increase is offset by overall population-based reductions in suicide associated with antidepressant treatment of youth depression (based on observational studies); and prevention with psychosocial interventions requires further evaluation. No review addressed sex or gender differences systematically, Aboriginal youth as a special population, harm, or cost-effectiveness. Consensus on 6 recommendations ranged from 73% to 100%. CONCLUSIONS: Our EKS facilitates decision maker access to what is known about effective youth suicide prevention interventions. A national research-to-practice network that links researchers and decision makers is recommended to implement and evaluate promising interventions; to eliminate the use of ineffective or harmful interventions; and to clarify prevention intervention effects on death by suicide, suicide attempts, and suicidal ideation. Such a network could position Canada as a leader in youth suicide prevention.

Sex differences in suicides among children and youth: the potential impact of misclassification.

OBJECTIVES: We examined whether established sex differences in suicide rates persist when adjustments are made for potential misclassification of deaths in children and youth. METHODS: This is a retrospective, descriptive study of 1294 suicides, 961 accidental and 254 undetermined deaths occurring between January 1, 2000 and December 31, 2007, among persons aged 10 to 25 years in Ontario, Canada. Using data from Coroner's records, causes of death were reclassified based on two different misclassification criteria. Actual and reclassified suicide rates were calculated by sex and age group (with 95% confidence intervals) and by year of death. RESULTS: Males aged 16-25 years accounted for the majority of suicides (68.9%). Asphyxia was the most common cause of suicide in both sexes. While suicides by shooting were almost exclusive to males, suicides due to alcohol/drug toxicity were significantly higher in females. Both before and after reclassification of suicide deaths, sex differences in suicide rates emerged in the 16-25 years age group. In each study year, both actual and reclassified suicide rates were higher in males than females. CONCLUSIONS: Sex differences in suicide rates emerging in adolescence are unlikely to be due to misclassification. Other proposed explanations for sex differences in youth suicide rates should be investigated further.

Developing measures of quality for the emergency department management of pediatric suicide-related behaviors.

OBJECTIVE: Given the public health importance of suicide-related behaviors and the corresponding gap in the performance measurement literature, we sought to identify key candidate process indicators (quality of care measures) and structural measures (organizational resources and attributes) important for emergency department (ED) management of pediatric suicide-related behaviors. METHODS: We reviewed nationally endorsed guidelines and published research to establish an inventory of measures. Next, we surveyed expert pediatric ED clinicians to assess the level of agreement on the relevance (to patient care) and variability (across hospitals) of 42 candidate process indicators and whether 10 hospital and regional structural measures might impact these processes. RESULTS: Twenty-three clinicians from 14 pediatric tertiary-care hospitals responded (93% of hospitals contacted). Candidate process indicators identified as both most relevant to patient care (≥87% agreed or strongly agreed) and most variable across hospitals (≥78% agreed or strongly agreed) were wait time for medical assessment; referral to crisis intervention worker/program; mental health, psychosocial, or risk assessment requested; any inpatient admission; psychiatric inpatient admission; postdischarge treatment plan; wait time for first follow-up appointment; follow-up obtained; and type of follow-up obtained. Key hospital and regional structural measures (≥87% agreed or strongly agreed) were specialist staffing and type of specialist staffing in or available to the ED; regional policies, protocols, or procedures; and inpatient psychiatric services. CONCLUSIONS: This study highlighted candidate performance measures for the ED management of pediatric suicide-related behaviors. The 9 candidate process indicators (covering triage, assessment, admission, discharge, and follow-up) and 4 hospital and regional structural measures merit further development.

Repeat self-harm: application of hurdle models.

Among those who present to the emergency department for self-harm, many will repeat. Self-harm repetition is an outcome of interest in both observational and intervention studies. However, few such studies analyse the number of repeat self-harm presentations. Here, hurdle models are introduced as a potentially useful statistical method for these analyses. Emergency department data from the Province of Ontario, Canada, are used to illustrate an example of implementing hurdle models and interpreting their results.

Pediatric suicide-related presentations: a systematic review of mental health care in the emergency department.

STUDY OBJECTIVE: We evaluate the effectiveness of interventions for pediatric patients with suicide-related emergency department (ED) visits. METHODS: We searched of MEDLINE, EMBASE, the Cochrane Library, other electronic databases, references, and key journals/conference proceedings. We included experimental or quasiexperimental studies that evaluated psychosocial interventions for pediatric suicide-related ED visits. Inclusion screening, study selection, and methodological quality were assessed by 2 independent reviewers. One reviewer extracted the data and a second checked for completeness and accuracy. Consensus was reached by conference; disagreements were adjudicated by a third reviewer. We calculated odds ratios, relative risks (RRs), or mean differences for each study's primary outcome, with 95% confidence intervals (CIs). Meta-analysis was deferred because of clinical heterogeneity in intervention, patient population, and outcome. RESULTS: We included 7 randomized controlled trials and 3 quasiexperimental studies, grouping and reviewing them according to intervention delivery: ED-based delivery (n=1), postdischarge delivery (n=6), and ED transition interventions (n=3). An ED-based discharge planning intervention increased the number of attended post-ED treatment sessions (mean difference=2.6 sessions; 95% CI 0.05 to 5.15 sessions). Of the 6 studies of postdischarge delivery interventions, 1 found increased adherence with service referral in patients who received community nurse home visits compared with simple placement referral at discharge (RR=1.28; 95% CI 1.06 to 1.56). The 3 ED transition intervention studies reported (1) reduced risk of subsequent suicide after brief ED intervention and postdischarge contact (RR=0.10; 95% CI 0.03 to 0.41); (2) reduced suicide-related hospitalizations when ED visits were followed up with interim, psychiatric care (RR=0.41; 95% CI 0.28 to 0.60); and (3) increased likelihood of treatment completion when psychiatric evaluation in the ED was followed by attendance of outpatient sessions with a parent (odds ratio=2.78; 95% CI 1.20 to 6.67). CONCLUSION: Transition interventions appear most promising for reducing suicide-related outcomes and improving post-ED treatment adherence. Use of similar interventions and outcome measures in future studies would enhance the ability to derive strong recommendations from the clinical evidence in this area.

Adolescent depression and emergency department use: the roles of suicidality and deliberate self-harm.

Depression is associated with increased health service use; clarifying the processes involved may offer strategies to reduce the disorder's individual and societal burdens. This review hypothesizes roles for suicidality and deliberate self-harm to partially explain a relationship between adolescent depression and increased emergency department use. Briefly, depression is associated with suicidality and deliberate self-harm, both of which are likely common among emergency department presentations in this age group. The overlap of depression with suicidality and deliberate self-harm has implications for suicide prevention strategies that emphasize diagnosing and treating adolescent depression. First, identifying and referring depression among these emergency department presentations is promising, but limitations must be addressed. Second, interventions for adolescent depression also may affect the health conditions associated with increased emergency department use, including suicidality and deliberate self-harm. However, much more research is needed on the pathways involved before such benefits, including cost offset, can be reasonably anticipated.

Age-sex differences in medicinal self-poisonings: a population-based study of deliberate intent and medical severity.

BACKGROUND: Deliberate self-harm (DSH) is related to suicide and DSH repetition is common. DSH hospital presentations are often self-poisonings with medicinal agents. While older age and male sex are known risk factors for suicide, it is unclear how these factors are related to the nature and severity of medicinal self-poisoning (SP). Such knowledge can guide prevention strategies emphasizing detecting and treating mental illness and controlling access to means. METHODS: Medicinal SP presentations by 18,383 residents of Ontario, Canada, aged 12 years and older, who presented to a hospital emergency department in that province between April 1, 2001-March 31, 2002 were characterized by the agents taken, identification of deliberate intent and medical severity. RESULTS: We found distinct age-sex differences in the nature and severity of medicinal SP. In youths, aged 12-17, about 40% of presentations involved analgesics, typically not prescribed and most often the acetaminophen agent-group. Females aged 12-64 were identified as deliberate more often than their male counterparts and this pattern occurred in most agent-groups, even among those who took antidepressants. The acetaminophen agent-group was most consistently associated with medical severity and this effect was strongest among female youths. Although medicinal SP was less frequent in the elderly, these presentations tended to be more medically serious and less often identified deliberate. CONCLUSIONS: The high proportion of medicinal SP in youths involving agents typically not prescribed and the medical severity of the acetaminophen agent-group underscore how prevention strategies must extend beyond controlling access to antidepressants. Despite a higher risk for suicide, males and the elderly may not have their deliberate intent detected and therefore, may not receive appropriate treatment. The emergency department can serve as important link to mental health care and usage patterns can provide feedback about the need for system-level enhancements and DSH surveillance.

Experiences of substance-using suicidal males who present frequently to the emergency department.

OBJECTIVE: This qualitative study investigated the repeated use of the emergency department (ED) by men with a history of suicidal behaviour and substance abuse to understand the needs and barriers to care for this high-risk group. Identification of common themes from interviews with patients and health care workers can serve as a basis for improved ED-based interventions. METHODS: Using semistructured interviews, patients, ED staff and family physicians were asked about needs of the aformentioned group. Twenty-five patients were interviewed and completed questionnaires regarding their substance use, aggression, parasuicidal behaviour, alexithymia and childhood trauma. In addition, 27 staff members were interviewed. Interviews were tape-recorded, transcribed and qualitatively analyzed using an iterative coding process. RESULTS: Of the 25 patients, 23 (96%) had a mood or anxiety disorder and 18 (75%) had borderline personality disorder. One-half of the patients scored high and another quarter scored moderate on alexithymia testing. The ED was viewed as a last resort despite seeking help. Frustration was felt by both patients and staff regarding difficult communication, especially during an acute crisis. CONCLUSION: The ED plays an important role in the provision of care for men with recurrent suicidal behaviour and substance abuse. Some of the diagnoses and problems faced by these patients are beyond the purview of the ED; however, staff can identify mutual goals for crisis interventions, allow for frequent communication and seek to de-escalate situations through the validation of the stress patients are experiencing.

Fragmented pathways to care: the experiences of suicidal men.

Using qualitative methods, this study examined how, and under what circumstances, suicidal men used mental health services. In particular, the analyses focused on fragmented pathways to care. Fifteen men with a history of suicidal and aggressive behaviors and a diagnosis of borderline personality disorder and/or antisocial personality disorder participated in semistructured interviews that consisted of questions about their mental health status and experiences with mental health and addiction services. Interviews were taped and transcribed. An iterative, inductive qualitative analytic process was used. Men followed a cyclical pattern wherein negative experiences with health care providers were said to be followed by avoidance of health care settings, crisis, and then by involuntary service utilization. Men identified five health care provider and three personal practices, and two types of episodes they believed to contribute to their fragmented pathways to care. Implementation of specialized interventions, and providing patients with more information and more opportunity to participate in decisions, may improve interactions between patients and providers and improve patients' mental health status.

Self-reported use of mental health services versus administrative records: care to recall?

Estimates of the level of unmet need for mental health treatment often rely on self-reported use of mental health services. However, depressed persons may over-report their use in relation to administrative records if they are highly distressed. This study seeks to replicate and explicate the finding that persons at a high level of distress report more mental health service use than recorded in their healthcare records. The study sample, N = 36,892, 12 years and older, was drawn from the 1996/97 Ontario portion of the Canadian National Population Health Survey. Respondents were individually linked to their administrative mental healthcare records 12 months backward in time. Of these, 96.5% agreed to the link and 23,063 (62.5%) were linked. Almost two-thirds of those who were depressed in the past year were currently at a high level of distress. Differential reporting of use for highly distressed persons in excess of 100% remained in the use of different types of physician providers after adjustments for other potential determinants of use. Telescoping was also not an explanation. The patterns of differential reporting between groups expected to diverge and converge in their recall ability were consistent with a recall bias. As this study was not able to rule out a recall bias, it further accentuates concerns about the impact of bias in the measurement of mental health-service use and inferences made concerning the determinants of use.

Self-reported use of mental health services versus administrative records: should we care?

Studies of mental health services have emphasized that people in need are not receiving treatment. However, these studies, based on self-reported use, may not be consistent with administrative records. This study compared self-reports of mental health service use with administrative records in a large representative sample. Respondent reports within the Ontario portion of the 1994/95 Household Component of the National Population Health Survey (NPHS) were individually linked to the provincial mental-health physician reimbursement claims. A total of 5187 Ontarians, aged 12 years or more, reported on their use of mental healthcare within the NPHS and 4621 (89%) consented and were successfully linked to administrative records. Comparisons between the two sources identified that the agreement for any use and volume of use was moderate to low and varied according to select respondent characteristics. These differences affected estimates of the associations with use and volume of use. People who reported high levels of distress reported more visits than those who did not and this effect was stronger in the self-reported data. These results suggest that recall bias may be present. Regardless of the definition of care, access for those in need remains a concern despite universal medical insurance coverage.

Gender and outpatient mental health service use.

The purpose of this study is to describe gender differences in the use of outpatient mental health services and to identify potential determinants of this use. The study sample, N = 7475 respondents 18-64 years, was drawn from the Mental Health Supplement to the Ontario Health Survey. For theoretical and empirical reasons, type of mental disorder was defined as: a Mood and/or Anxiety Disorder (Mood/Anx) or a Substance Use Disorder and/or Antisocial Behaviours (Subs/Asb) within the past year. Use was defined in relation to providers seen within the past year. Descriptive and multiple logistic regression analyses were employed including type of mental disorder, social and economic factors. Female gender remained positively associated with any use despite adjustments (adjusted OR: 1.7; 95% CI: 1.2: 2.4). The magnitude of this association was consistent across the levels of the study variables and various measures of use except volume of use where there were no gender differences. Mood/Anx appeared to mediate the gender-use relationship and was strongly associated with use (adjusted OR: 8.4; 95% CI: 5.9; 11.9). Subs/Asb was also related to use (adjusted OR: 2.6; 95% CI: 1.5; 4.3) but not to the same degree as Mood/Anx. Mood/Anx explained 60% of the crude Subs/Asb-use relationship. The evidence to suggest that Subs/Asb mediated the gender-use relationship was mixed. These findings raise questions about gender differences in illness and reporting behaviours and the health care system in its preferential treatment of women and those with Mood/Anx.
