Suicide Risk in Primary Care: Identification and Management in Older Adults

The National Strategy for Suicide Prevention (2012) has set a goal to reduce suicides by 20 % within 5 years. Suicide rates are higher in older adults compared to most other age groups, and the majority of suicide completers have visited their primary care physician in the year before suicide. Primary care is an ideal setting to identify suicide risk and initiate mental health care. We review risk factors for late-life suicide; methods to assess for different levels of suicidality; and recent research developments regarding both effective assessment and management of suicide risk among older primary care patients. We highlight that broader scale screening of suicide risk may be considered in light of findings that suicidality can occur even in the absence of major risk factors like depression. We also highlight collaborative care models targeting suicide risk, and recent innovative interventions that aim to prevent the development of suicidal ideation and suicidal behavior.     

Reasons for living,meaning in life,and suicide ideation: investigating the roles of key positive psychological factors in reducing suicide risk in community-residing older adults

Objectives: To investigate the roles of reasons for living (RFL) and meaning in life (MIL) in potentially promoting mental health and well-being and protecting against suicide ideation among community-residing older adults and to investigate the psychometric properties of the Reasons for Living Scale-Older Adult version (RFL-OA).

Method: Of 173 older adults initially recruited into a longitudinal study on late-life suicide ideation, 109 completed the RFL-OA and measures of cognitive and physical functioning and positive and negative psychological factors at a two-year follow-up assessment. We tested a model in which RFL and MIL protect against suicide ideation, controlling for demographic and clinical factors. We also assessed the psychometric properties of the RFL-OA in community-residing older adults, investigating its internal consistency and its convergent (MIL, perceived social support, and life satisfaction), divergent (loneliness, depressive symptom severity, and suicide ideation), and discriminant validity (cognitive and physical functioning).

Results: RFL-OA scores explained significant variance in suicide ideation, controlling for age, sex, depressive symptom severity, and loneliness. MIL explained significant unique variance in suicide ideation, controlling for these factors and RFL, and MIL significantly mediated the association between RFL and suicide ideation. Psychometric analyses indicated strong internal consistency (α = .94), convergent, divergent, and discriminant validity for the RFL-OA relative to positive and negative psychological factors and cognitive and physical functioning.

Conclusion: These findings add to a growing body of literature suggesting merit in investigating positive psychological factors together with negative factors when assessing suicide risk and planning psychological services for older adults.     

Trends in Suicide Methods and Rates among Older Adults in South Korea: A Comparison with Japan

Objective

Lethality of the chosen method during a suicide attempt is a strong risk factor for completion of suicide. We examined whether annual changes in the pattern of suicide methods is related to annual changes in suicide rates among older adults in South Korea and Japan.

Methods

We analyzed annual the World Health Organization data on rates and methods of suicide from 2000 to 2011 in South Korea and Japan.

Results

For Korean older adults, there was a significant positive correlation between suicide rate and the rate of hanging or the rate of jumping, and a significant negative correlation between suicide rate and the rate of poisoning. Among older adults in Japan, annual changes in the suicide rate and the pattern of suicide methods were less conspicuous, and no correlation was found between them.

Conclusion

The results of the present study suggest that the increasing use of lethal suicide methods has contributed to the rise in suicide rates among older adults in South Korea. Targeted efforts to reduce the social acceptability and accessibility of lethal suicide methods might lead to lower suicide rate among older adults in South Korea.     

Understanding suicide among older adults: a review of psychological and sociological theories of suicide

Objectives: Older adults die by suicide at a higher rate than any other age group in nearly every country globally. Suicide among older adults has been an intractable clinical and epidemiological problem for decades, due in part to an incomplete understanding of the causes of suicide, as well as imprecision in the prediction and prevention of suicidal thoughts and behaviors in later life. Theory-driven investigations hold promise in addressing these gaps by systematically identifying testable, and thus falsifiable, mechanisms that may better explain this phenomenon and also point to specific interventions.

Method: In this article, we comprehensively review key extant psychological and sociological theories of suicide and discuss each theory's applicability to the understanding and prevention of suicide among older adults.

Results: Despite a modest number of theories of suicide, few have undergone extensive empirical investigation and scrutiny, and even fewer have been applied specifically to older adults.

Conclusion: To advance the science and contribute findings with a measurable clinical and public health impact, future research in this area, from conceptual to applied, must draw from and integrate theory.     

Coping and thought suppression as predictors of suicidal ideation in depressed older adults with personality disorders

Suicide rates are higher among older adults than any other age group and suicidal ideation is one of the best predictors of completed suicide in older adults. Despite this, few studies have evaluated predictors of suicidal ideation and other correlates of death by suicide (e.g. hopelessness) among older adults. Even fewer studies on this topic have been conducted among samples characterized as poor responders to treatments (e.g. depressed individuals with co-occurring personality disorder). The purpose of this study was to examine coping styles and thought suppression as predictors of a suicide risk composite score in a sample of depressed older adults with co-occurring personality disorders. Based on the extant literature, it was hypothesized that maladaptive coping (i.e. emotional and avoidance coping) and chronic thought suppression would significantly predict suicide risk. The results of this study indicated that elevated emotional coping and thought suppression were associated with increased suicide risk. Contrary to hypotheses, lower avoidance coping was associated with increased risk, although this finding is moderated by Axis II diagnosis Thus, treatments that focus on decreasing emotional coping and chronic thought suppression may result in decreased suicidal ideation and hopelessness for older adults with depression and Axis II pathology.     

Suicide and Aging: International Perspectives

From Durkheim to Kraepelin, suicide has been recognized as a social and psychiatric ill. Among clinical scientists in the United States, interest in suicide grew substantially in the 1980's as rates among older adults increased. However, major advances in the science of mental health seem unlikely to reduce the prevalence of suicide as long as case recognition at the community level continues to be problematic. Public policy promoted to reduce social risk factors coupled with greater attention to psychopathology is the logical outgrowth from the most recent data. Differences in suicide rates by nation add weight to the argument.     

The sex distribution of suicides by age in nations of the world

Summary The ratio of the male suicide rate to the female suicide rate for each age group in 31 nations of the world was found to be associated with the wealth of the nations. The male/female suicide rate ratio was lower in wealthier nations for older adults and higher in wealthier nations for youths. The male-female suicide rate ratio was associated over the nations among the younger age groups and also among the older age groups. These results suggest that the sex ratio may be differently determined in youths and in older adults.     

Relationships among dispositional coping strategies, suicidal ideation, and protective factors against suicide in older adults

Older adults have a disproportionally high rate of completed suicide as compared to the general population. Whereas a large literature has focused on risk factors related to elder suicide, limited research exists on relationships between coping strategies with protective factors against suicide and suicidal ideation in this population. Community-dwelling older adults (N = 108, mean age = 71.5 years, age range = 60-95 years) completed the Coping Orientations to Problems Experienced scale, Reasons for Living inventory, and Geriatric Suicide Ideation Scale (GSIS). Problem- and emotion-focused coping were associated positively with reasons for living and negatively with suicide ideation. Dysfunctional coping was associated positively with suicide ideation, but results did not support the hypothesized negative relationship with reasons for living. Thus, problem- and emotion-focused coping appear to be adaptive, whereas dysfunctional coping appears to be somewhat less related to resilience to suicidal ideation among community-dwelling older adults. Implications of the study are that some coping strategies may serve as protective factors against suicide and that coping strategies should be evaluated as part of a thorough assessment of suicidal risk among older adults. The results also provide some evidence of convergent validity for the recently developed GSIS.     

Issues in research on aging and suicide

Objective: Late-life suicide is a complex clinical and public health problem.

Method: In this article, some of the key complexities inherent in studying late-life suicide are discussed in the service of promoting high-quality late-life suicide prevention science.

Results: We discuss the following research issues: the relatively greater lethality of suicidal behavior in later life (compared to younger ages); the lack of data on whether thoughts of death in later life are indicators of suicide risk; the fact that older adults do not tend to seek specialty mental health care, necessitating moving research into primary care clinics and the community; the lack of theory-based research in late-life suicide; the unclear role of cognitive impairment; and the promise of taking a ‘patient centered’ and ‘participatory research’ approach to late-life suicide research efforts.

Conclusion: We believe that these perspectives are too often not capitalized upon in research on suicide prevention with older adults and that voice of the older person could contribute much to our understanding of why older adults think about and act on suicidal thoughts, as well as the most acceptable ways to reach and intervene with those at risk.     

Suicide and its prevention among older adults.

OBJECTIVE: To review the research on the epidemiology, risk and resiliency, assessment, treatment, and prevention of late-life suicide. METHOD: I reviewed mortality statistics. I searched MEDLINE and PsycINFO databases for research on suicide risk and resiliency and for randomized controlled trials with suicidal outcomes. I also reviewed mental health outreach and suicide prevention initiatives. RESULTS: Approximately 12/100,000 individuals aged 65 years or over die by suicide in Canada annually. Suicide is most prevalent among older white men; risk is associated with suicidal ideation or behaviour, mental illness, personality vulnerability, medical illness, losses and poor social supports, functional impairment, and low resiliency. Novel measures to assess late-life suicide features are under development. Few randomized treatment trials exist with at-risk older adults. CONCLUSIONS: Research is needed on risk and resiliency and clinical assessment and interventions for at-risk older adults. Collaborative outreach strategies might aid suicide prevention.     

Recent research on suicide in the elderly

Older adults, and older men in particular, are the segment of the US population that has the highest suicide rate. Although research on risk factors continues to grow, there remains limited knowledge of the biologic changes that increase risk for suicide, as well as limited information about contributing psychosocial processes that extend beyond demographic factors. No proven interventions are known at this time, although efforts are underway to test approaches that reach older adults who use primary care services. Continued efforts are needed to change attitudes about mental illness and treatment in order to reach older adults who do not use health care services.     

Suicide among older psychiatric inpatients: an evidence-based study of a high-risk group.

OBJECTIVE: Older adults have elevated suicide rates, especially in the presence of a psychiatric disorder, yet not much is known about predictors for suicide within this high-risk group. The current study examines the characteristics associated with suicide among older adults who are admitted to a psychiatric hospital. METHOD: All persons aged 60 and older living in Denmark who were hospitalized with psychiatric disorders during 1990-2000 were included in the study. Using a case-control design and logistic regression analysis, the authors calculated the suicide risk associated with specific patient characteristics. RESULTS: Affective disorders were found to be associated with an almost twofold higher risk of suicide among psychiatric inpatients than other types of disorders (95% confidence interval [CI]: 1.5-2.6). Patients with dementia had a significantly lower risk ratio of 0.2 (95% CI: 0.1-0.3). In combination with other types of disorder, affective disorders were found to modify an increased risk of suicide. First versus later admission for depression was a better predictor for suicide than age at first hospitalization for depression (before or after age 60 years). More than half of suicides occurred either within the first week of admission or discharge (chi(2) [1] = 27.70, p <0.001) compared with the distribution of patient days. CONCLUSIONS: Our findings underline the important role of affective disorder in combination with other types of disorders. Assessment of suicide risk among older psychiatric inpatients should take current or previous episodes of affective illness into consideration and pay special heed to the time shortly after admission and discharge.     

The mediating effect of perceived burdensomeness on the relation between depressive symptoms and suicide ideation in a community sample of older adults

Objectives: Suicide is a prevalent problem in older adults. One of the best predictors of suicide in older adults is suicide ideation; suicide ideation has been frequently associated with depression. However, suicide ideation is not always present when an older adult is depressed and is sometimes present when an older adult is not depressed. Perceived burdensomeness, a recently proposed risk factor [Joiner Jr, T.E. (2005)], has been linked to suicide ideation in depressed samples and in older adults. Thus, perceived burdensomeness may be the necessary risk factor for suicide ideation.

Method: The Geriatric Suicide Ideation Scale (GSIS; [Heisel et al. (2006)]), Center for Epidemiologic Studies Depression (CES-D; [Radloff, L.S. (1977)]) scale, and Suicide Cognitions Scale (SCS; [Rudd, M.D., Schmitz, B., McClenen, R., Joiner, T., Elkins, G., &; Claassen, C.A. (n.d.)]) were completed by a community sample of older adults recruited from primary care clinics (n?=?106). A regression analysis was conducted following Baron and Kenny's [1986] guidelines to test the hypothesis that perceived burdensomeness (measured by the SCS perceived burdensomeness subscale) mediates the relation between depression (assessed with the CES-D) and suicide ideation (measured by the GSIS suicide ideation subscale) in older adults.

Results: Perceived burdensomeness mediated the relation between depression and suicide ideation, accounting for 68.3% of the variance in suicide ideation.

Conclusion: Perceived burdensomeness may explain the relation between depression and suicide ideation. Clinicians seeing older adults should assess for depression and perceived burdensomeness when determining suicide risk. Future research directions include treatment studies for perceived burdensomeness as a way to reduce suicide ideation.     

Age-specific characteristics of attempted suicide in adolescence

A total of 422 suicide attempts of adolescents (15 to 19 years of age) were investigated and compared with 327 suicide attempts of young adults. Adolescents had more serious social problems than young adults. Their adaptive problems became worse while growing older until the age of 20. Adolescents made suicide attempts with serious intent more often than young adults, but their suicide attempts were not as often lethal as in young adults. Although repeated suicide attempts were relatively common in both groups, only 10 people were part of both materials. Adolescents were as often psychotic when attempting suicide as young adults were. Twenty-four percent of adolescents and 26% of young adults were admitted to a psychiatric hospital as treatment.     

Suicides in Late Life

Suicide in late life is an enormous public health problem that will likely increase in severity as adults of the baby boom generation age. Data from psychological autopsy studies supplemented with recent studies of suicidal ideation and attempts point to a consistent set of risk factors for the spectrum of suicidal behaviors in late life (suicide ideation, attempts, and deaths). Clinicians should be vigilant for psychiatric illness (especially depression), physical illness, pain, functional impairment, and social disconnectedness. Recent advances in late-life suicide prevention have in common collaborative, multifaceted intervention designs. We suggest that one mechanism shared by all preventive interventions shown to reduce the incidence of late-life suicide is the promotion of connectedness. For the clinician working with older adults, our recommendation is to not only consider risk factors, such as depression, and implement appropriate treatments but to enhance social connectedness as well.     

A Qualitative Analysis of Suicide Notes to Understand Suicidality in Older Adults

ObjectiveSuicide is a complex multifactorial process influenced by a variety of biological, psychological, and social stressors. Many older adults face a characteristic set of challenges that predispose them to suicidal ideation, suicide-related behavior, and death by suicide. This study explored the subjective experience of suicidality through the analysis of suicide notes from older adults.DesignQualitative study analyzing written suicide notes.SettingWritten notes for suicide deaths in Toronto, Canada, between 2003 and 2009 were obtained from the Office of the Chief Coroner for Ontario.ParticipantsThe analysis comprised 29 suicide notes (mean words per note: 221; range: 6–1095) written by individuals 65 years and older (mean ± SD age: 76.2 ± 8.3).MeasurementsWe employed a constructivist grounded theory framework for the analysis, conducted through line-by-line open coding, axial coding, and theorizing of data to establish themes.ResultsSuicide notes elucidated the writers’ conception of suicide and their emotional responses to stressors. Expressed narratives contributing to suicide centered on burdensomeness or guilt, experiences of mental illness, loneliness or isolation, and poor physical health or disability. Terms related to pain, poor sleep, apology, and inability to go on were recurrent.ConclusionsSuicide notes enrich our understanding of the thoughts and emotions of those at highest risk of suicide, and they inform potential interventions for reducing suicide risk in older adults.     

Coping and health in older adults

Although coping has been shown to influence physical health in younger populations, whether coping affects health in older adults appears to depend upon how coping and health are conceptualized. This article reviews recent literature on coping and health in older adults in three areas. First, we discuss coping’s distinct relevance to health in older adults. Second, we describe ways in which coping may differ between older and younger populations. Third, we detail recent and notable findings of coping’s specific effects on biomedical health and health in general. The recent literature suggests that coping may be a developmental and multifaceted process. Positive coping strategies may have positive and even protective effects on health, whereas negative strategies may have negative effects.     

Investigating the psychometric properties of the Geriatric Suicide Ideation Scale (GSIS) among community-residing older adults

Objectives: To investigate the psychometric properties of the Geriatric Suicide Ideation Scale (GSIS) among community-residing older adults.

Method: We recruited 173 voluntary participants, 65 years and older, into a 2+ year longitudinal study of the onset or exacerbation of depressive symptoms and suicide ideation. We assessed the internal consistency of the GSIS and its four component subscales, and its shorter and longer duration test–retest reliability, convergent (depression, social hopelessness, and loneliness), divergent (psychological well-being, life satisfaction, perceived social support, and self-rated health), discriminant (basic and instrumental activities of daily living and social desirability), criterion (history of suicide behavior), and predictive validity (future suicide ideation).

Results: The GSIS demonstrated strong test–retest reliability and internal consistency. Baseline GSIS scores were significantly positively associated with suicide risk factors, negatively associated with potential resiliency factors, and not associated with functional impairment or social desirability. GSIS scores significantly differentiated between participants with as compared to those without a history of suicide behavior. Baseline GSIS scores significantly predicted suicide ideation at a 2+ year follow-up assessment.

Conclusion: Findings suggest strong measurement characteristics for the GSIS with community-residing older adults, including impressive consistency over time. These results are consistent with research attesting to the empirical and pragmatic strengths of this measure. These findings have implications for the monitoring of suicide risk when aiming to enhance mental health and well-being and prevent suicide in later life.     

Identifying the Social Demographic Correlates of Suicide Bereavement

We investigated the demographic correlates associated with suicide bereavement among a representative sample of U.S. adults from the 2016 General Social Survey. A secondary aim of this study was to use this representative data platform to cross-check official data findings of U.S. completed suicides. Questions on suicide bereavement were administered to 1,432 GSS 2016 respondents and these were cross-tabulated with various demographic and social activity variables included in this omnibus survey to investigate whether suicide bereaved respondents shared any distinctive demographic characteristics. Findings showed that friends of the suicide deceased person outnumbered the deceased’s first degree relatives by at least 2 to 1. We also observed older, White, Non-Hispanic, and native born women were over-represented among the suicide bereaved. The suicide bereaved were also less likely to live in the Pacific region, and to live in the nation’s largest cities, and were more likely to come from homes where a gun was owned by someone in the household. More of the suicide bereaved reported themselves to be in poorer physical health and bereaved women were more likely to be Facebook subscribers. These findings are consistent with other data on U.S. suicide patterns and the greater likelihood of firearms being utilized in suicide deaths. These revealed demographic correlates of suicide offer valuable information to helping agencies seeking to reach potential clients among the suicide bereaved.
