Personality and Suicidal Behavior in Old Age: A Systematic Literature Review

Six-year course over time and predictors of suicidal ideation in depressed older patients

BACKGROUND

It is important to know predictors of long-term course over time of suicidal thoughts and ideation in depressed older persons.

METHODS

In this study, 378 depressed older persons were interviewed at baseline, and after 2 and 6 years to evaluate the presence of depressive disorder. The Inventory of Depressive Symptomatology (IDS) was administered every 6 months for 6 years. Latent Class Growth Analysis was performed on the IDS item on suicidal ideation to identify subgroups with different trajectories.

RESULTS

Five subgroups with suicidal ideation trajectories were identified: 1) severe, transient (10.9 %), 2) severe, persisting (8.0 %), 3) mild, but increasing (14.9 %), 4) moderate, persisting (35.6 %), and 5) no thoughts (30.6 %). Mixed model analysis showed that trajectories were related to 6-year course of depressive symptoms. Yet, suicidal ideation or thoughts of loss of meaning of life were still present in 22.7 % and 17.4 % of those who remitted after 2 and 6 years. Independent of baseline depressive symptom severity, loneliness, childhood trauma, history of suicidal ideation or attempt, openness to experience, earlier age of depression onset, anxiety symptom severity and worse mastery predicted worse trajectories.

LIMITATIONS

47 % dropped out at 6-years follow-up, we did not distinguish between thoughts of death and suicide, we did not assess death by suicide.

CONCLUSIONS

Although trajectories of suicidal ideation and thoughts of loss of meaning of life were strongly related to the course of depression severity, they also appear after remission. Clinicians should be vigilant for suicidal ideation or death wish, even after remission of depression.

Brooding, reflection, and anger rumination in late life suicidal behavior

BACKGROUND

Current literature on age-specific risk factors for suicide in older adulthood is lacking. One risk factor for younger-life suicide, rumination, has not been extensively studied in older adults, but from prior research, may be more relevant to late-life vs. early life suicide. The current study investigated how multiple subtypes of rumination (i.e., brooding, reflection, and anger rumination) relate to suicidal ideation and recent suicidal behavior in late life.

METHODS

378 participants aged 50-90 (mean age 63.4, SD 7.5) were recruited into a case-control study examining suicide in older adults. Participants were recruited into three groups: 1) depressed adults who had made a recent (past two years) suicide attempt, 2) those with depression but no suicide attempt, and 3) a healthy comparison group. Among depressed groups, we examined relationships between rumination types, trait anger, depression, and suicidal ideation. Then, we conducted logistic regression to test which variables were related to having made a suicide attempt in the past two years among those with current suicidal ideation.

RESULTS

All forms of rumination were related to depression. Brooding was related to ideation severity, but only depression severity related to presence of ideation. Anger rumination and ideation severity each contributed unique variance in their prediction of recent suicide attempts.

LIMITATIONS

Our cross-section design does not allow for causal claims; future studies should consider using ecological momentary assessment approaches.

CONCLUSIONS

Treatments to decrease rumination without an intense cognitive component should be considered for late-life patients.

Older adults make sense of their suicidal behavior: a Swedish interview study

Introduction

The aim of this study was to explore how individuals aged 70 or older living in Sweden understood a recent suicidal act, and what changed in them and around them in the aftermath.

Method

Four women and five men (age range 71-91 years) receiving care at a geriatric psychiatric outpatient clinic in a large Swedish city took part in two interviews about their most recent suicidal act. Most of the women and none of the men had engaged in prior suicidal acts. Interpretative phenomenological analysis was employed.

Results

The suicidal act was explained as a response to losses (in physical and cognitive functions, social roles and relationships) that rendered previous coping strategies unviable. The participants reported being dependent on a healthcare system that they experienced as indifferent and even dismissive of their suffering. The suicidal act was described as an unplanned act of despair. Positive changes followed for participants who reported having had suicidal ideation prior to the suicidal act and had insights into its triggers. Some gained access to needed medical care; others developed greater awareness of their psychological needs and became more effective at coping. Individuals who said that they had not had suicidal thoughts prior to the suicidal act and could not explain it reported no positive change in the aftermath. The respondents' narratives indicated gendered themes.

Discussion

Participants' age-related losses were in many cases exacerbated by negative interactions with health care providers, indicating that continued attention needs to be given to implicit ageism in medical professionals. The suicidal acts were described as impulsive, which was unexpected because a dominant belief is that older adult suicidal behavior is planned. One reason for the discrepancy may be that this study focused on nonfatal acts, and planned acts may be more likely to be fatal. Another reason could be shame due to suicide stigma. Alternatively, these acts were truly unplanned. The older adult suicide planning question should be addressed in larger studies across geographical and cultural settings. Future studies should also include questions about gender norms of suicidality and separately examine women's and men's data.

Psychological mechanisms of the development of suicidal ideation: Longitudinal cohort study

INTRODUCTION

This study aimed to investigate the mechanisms of the development of suicidal ideation and its moderating and protective factors. Drawing on the Interpersonal-psychological theory of suicide, we proposed that disruptions to belongingness, in conjunction with tolerance of health risk, may influence the development of suicidal ideation above and beyond psychosocial changes such as disruptions to finances and work.

METHODS

The study involved a longitudinal investigation of an Australian representative sample reporting suicidal ideation fortnightly for 12 weeks between March and June 2020.

RESULTS

The results indicated that participants who reported higher levels of belongingness, mastery, and intolerance of health risk were less likely to experience suicidal ideation and had lower severity of suicidal ideation. Mastery significantly strengthened the negative link between belongingness and the incidence of suicidal ideation, while agreeableness significantly strengthened the negative link between belongingness and the severity of suicidal ideation over time.

CONCLUSION

The findings suggest that supporting effective social connectedness during times of isolation and promoting self-efficacy, mastery, and regulation of risk tolerance, may be crucial for suicide prevention and therapeutic intervention.

Symptoms characteristics of personality disorders associated with suicidal ideation and behaviors in a clinical sample of adolescents with a depressive disorder

Introduction

Pathological personality traits have repeatedly been identified as important risk factors for suicidal ideation and behaviors. Moreover, impulsive-aggressive traits, have shown a consistent association with suicidal behaviors across the lifespan. Adolescence represents a critical period for the emergence of different personality traits, mood disorders, and suicidal behaviors, but the relationship between these variables remain poorly understood.

Methods

These variables were examined in a cross-sectional case-control design involving three groups: 30 adolescents with a depressive disorder and past suicide attempt (Mean Age = 16.2, Females = 26), 38 adolescents with a depressive disorder but without past suicide attempt (Mean age = 16.0, Females = 29), and 34 healthy adolescent controls (Mean age = 15.2, Females = 22). Suicidal ideations were indexed using Suicidal Behavior Questionnaire (SBQ-R), psychiatric disorder assessed using a semi-structured questionnaire (K-SADS-PL), depressive symptoms with the Beck Depressive Inventory (BDI), symptoms characteristics of personality disorders with the Scheduled Clinical Interview for the DSM-IV (SCID-II) screening questionnaire, and impulsivity with the Barratt Impulsivesness Scale (BIS).

Results

Findings showed that impulsivity (F = 11.0, p < 0.0001) and antisocial symptoms characteristics of personality disorders (p < 0.001, d = 0.70) displayed the most robust association with adolescent suicide attempts. Borderline symptoms characteristics of personality disorders did not discriminate attempters from non-attempters but presented high correlations with suicidal ideation and depression severity. In an item-wise analysis, suicide attempt status was uniquely correlated with symptoms characteristics of an antisocial personality disorder. Suicide attempt status also correlated with non-suicidal self-injury and a chronic feeling of emptiness.

Discussion

The caveats of this cross-sectional study include the stability of symptoms characteristics of personality disorders in adolescence and the limited sample size. In sum, suicidal behaviors were characteristically correlated with increased impulsivity and antisocial symptoms characteristics of personality disorders, but other symptoms characteristics of personality disorders were relevant to adolescent depression and suicidal ideation. Understanding the emergence of symptoms characteristics of personality disorders and suicidal behaviors in a developmental context can ultimately inform not only the neurobiological origin of suicidal behaviors, but also provide new avenues for early detection and intervention.

Development of mental health first-aid guidelines for suicide risk: a Delphi expert consensus study in Argentina and Chile

BACKGROUND

Suicide continues to pose a significant global public health challenge and ranks as one of the leading causes of death worldwide. Given the prevalence of suicide risk in the community, there is a significant likelihood of encountering individuals who may be experiencing suicidal thoughts or plans, creating an opening for non-health professionals to offer support. This study aims to culturally adapt the original Australian Mental Health First Aid Guidelines for suicide risk to the Chilean and Argentine context.

METHODS

A two-round Delphi expert consensus study was conducted involving two panels, one comprising individuals with personal experience in suicide thoughts/attempts or caregiving for those with such experiences (n = 18), and the other consisting of professionals specialized in suicide assessment and support for individuals at risk (n = 25). They rated a total of 179 items mainly derived from guidelines developed by Australian experts and translated into Spanish (168), and new items included by the research team (11). The panel members were requested to assess each item utilizing a five-point Likert scale. During the second round, items that received moderate approval in the initial round were re-evaluated, and new items suggested by the local experts in the first round were also subjected to evaluation in the next round. Inclusion in the final guidelines required an 80% endorsement as "essential" or "important" from both panels.

RESULTS

Consensus of approval was reached for 189 statements. Among these, 139 statements were derived from the English-language guidelines, while 50 locally generated statements were accepted during the second round. A significant difference from the original guideline was identified concerning the local experts' reluctance to discuss actions collaboratively with adolescents. Furthermore, the local experts proposed the inclusion of an entirely new section addressing suicide risk in older individuals, particularly focusing on suicide methods and warning signs.

CONCLUSIONS

A Delphi expert consensus study was conducted to culturally adapt mental health first aid guidelines for assessing suicide risk in Chile and Argentina. This study involved professionals and individuals with lived experience. While many items were endorsed, some related to inquiring about suicide risk and autonomy, particularly for adolescents, were not. An additional section for older individuals was introduced. Future research should explore the implementation and impact of these adapted guidelines in training courses. This is vital for enhancing mental health support and implementing effective suicide prevention strategies in Chile and Argentina.

Syntactic Errors in Older Adults with Depression

Background and Objectives: This study investigated the differences in syntactic errors in older individuals with and without major depressive disorder and cognitive function disparities between groups. We also explored the correlation between syntax scores and depression severity. Materials and Methods: Forty-four participants, assessed for dementia with the Mini-Cog, completed the 15-item Geriatric Depression Scale (TGDS-15) and specific language tests. Following a single-anonymized procedure, clinical psychologists rated the tests and syntax scores. Results: The results showed that the depressive disorders group had lower syntax scores than the non-depressed group, primarily on specific subtests. Additionally, cognitive test scores were generally lower among the depressed group. A significant relationship between depression severity and syntax scores was observed (r = -0.426, 95% CI = -0.639, -0.143). Conclusions: In conclusion, major depressive disorder is associated with reduced syntactic abilities, particularly in specific tests. However, the relatively modest sample size limited the sensitivity of this association. This study also considered the potential influence of cultural factors. Unique linguistic characteristics in the study's context were also addressed and considered as potential contributors to the observed findings.

Depression and Its Associated Factors among Undergraduate Engineering Students: A Cross-Sectional Survey in Thailand

BACKGROUND

Depression is a common mental health problem that can affect everyone at different stages of development. Though the prevalence rate of depression among university students is rising, exploration among engineering students is limited. The aim of the study was to examine the prevalence of depression and its associated factors of among engineering students in Thailand.

METHODS

A total of 346 students participated in this study. All completed the outcome inventory depression subscale (OI-D) to evaluate the level and prevalence of depression. Other variables assessed included social skills, learning styles, relationship satisfaction, interpersonal difficulty, alcohol use, internet addiction, and neuroticism. Correlation and regression analyses were applied to test the association between sociodemographic and psychosocial factors and depression.

RESULTS

Of the 346 students with the mean age of 20.25 (SD, 1.33), 52.31% were male. Based on the OI-D, 35.3% of participants exhibited symptoms indicative of major depression. Multiple regression showed that only neuroticism, interpersonal difficulties, social skills, and self-esteem appeared to be the significant predictors of depression.

CONCLUSION

The prevalence of depression among engineering students in Thailand was unexpectedly high compared with the prevalence of depression among engineering students in some other countries. Intra- and interpersonal factors were found to be associated with depression. Further study on identifying these risk factors should be encouraged.

The mediating effects of personality traits on the relationship of youth conduct problems and mood disorders with adulthood suicidality

Identifying the relevant factors for suicidality in individuals with conduct problems is a public health concern, especially if they were under the influence of mood disorders later in life. This study investigates the relationship between youth conduct problems and mood disorders and adulthood suicidality, and to further explore the mediating effects of personality on this relationship. A retrospective cohort study was administered to 308 individuals aged 20-65 years, with or without mood disorders diagnosed by psychiatrists. The Composite International Diagnosis Interview was used to evaluate conduct problems in youth and suicidality (i.e., suicide plan and suicide attempt) in the past year. Personality traits were assessed using Eysenck Personality Questionnaire-Revised for extraversion and neuroticism. Multiple-mediator analysis was used to investigate the mediation effects of personality traits on the relationship between conduct problems and suicidality. The average age of enrolled participants was 31.6 years, and 42.5% of them were female. 39.2% reported suicidality and 43.2% reported conduct problems in youth. Participants who were diagnosed with mood disorders (p < 0.001) and reported having conduct problems (p = 0.004) were associated with high suicidality. Multiple-mediator analysis showed that conduct problems in youth increased the risk of adulthood suicidality through the indirect effects of higher neuroticism (suicide plan: OR = 1.30, BCA 95% CI = 1.04-1.83; suicide attempt: OR = 1.27, BCA 95% CI = 1.05-1.66). Neuroticism mediates the association between youth conduct problems and adulthood suicidality. This finding raises our attention to assess personality traits in individuals with youth conduct problems for designing proper intervention strategies to reduce the risk of suicide.

Suicidal ideation among men during COVID-19: Examining the roles of loneliness, thwarted belongingness, and personality impairment

Suicidal ideation (SI) is a known precursor to suicide among men. While loneliness and thwarted belongingness (TB) have been identified as key factors influencing SI, no study has reported on all three constructs to investigate whether loneliness is associated with SI by way of TB. Furthermore, it is not clear whether personality impairment has a moderating role on this process. The present study examined the impact of loneliness on SI among men and whether TB mediated this relationship. Additionally, the study investigated whether personality impairment (i.e., self-functioning, interpersonal functioning) moderated the relationship between loneliness and TB. Canadian men (N = 434) completed an online survey that included self-report assessments of the study constructs. Conditional process modeling was used to test the indirect effect of loneliness on SI via the mediating effect of TB. Findings indicated a significant association between loneliness and SI that was mediated by TB. Further, impairment in self-functioning moderated the relationship between loneliness and TB, indicating that the relationship was stronger among men with greater difficulties in self-functioning. The findings are important to consider within the COVID-19 context, as they point to the need to reduce the detrimental impacts of loneliness, thereby potentially mitigating male SI.

What distinguishes high and low-lethality suicide attempts in older adults? A systematic review and meta-analysis

Those making suicide attempts with highly lethal medical consequences are arguably the best proxy for those who die by suicide and represent a qualitatively different population from those making lower lethality attempts. Different factors influence the likelihood of a suicide attempt occurring and the lethality of that attempt. Both are important dimensions of risk. Older adults represent a distinct group in suicide research with unique risk factors that influence the lethality of their suicide attempts. This systematic review and meta-analysis summarises factors distinguishing those making high and low-lethality suicide attempts in older adulthood. Databases PsycINFO, PubMed (MEDLINE), Embase and CINAHL were systematically searched with seven of 1182 unique records included. Random effects meta-analyses were conducted on 18 variables in addition to a narrative synthesis regarding executive function. Only increased suicidal intent and planning meaningfully distinguished high from low-lethality attempters in meta-analyses. A large effect size was additionally observed for white ethnicity. Diminished alcohol use disorder prevalence and depression severity, and greater cognitive impairment, may be associated with high lethality attempters but further research is needed. Age and gender were not associated with lethality, contrary to adult populations. A narrative synthesis of studies exploring differences in executive functioning suggested high-lethality attempters were less likely to impulsively act on suicidal urges, allowing them to better plan suicide attempts that are more lethal, and are less likely to alter suicidal plans. Key limitations were that meta-analyses were underpowered to detect small effect sizes, and samples were largely white and limited to the USA.

Suicide and self-harm

Suicide and self-harm are major health and societal issues worldwide, but the greatest burden of both behaviours occurs in low-income and middle-income countries. Although rates of suicide are higher in male than in female individuals, self-harm is more common in female individuals. Rather than having a single cause, suicide and self-harm are the result of a complex interplay of several factors that occur throughout the life course, and vary by gender, age, ethnicity, and geography. Several clinical and public health interventions show promise, although our understanding of their effectiveness has largely originated from high-income countries. Attempting to predict suicide is unlikely to be helpful. Intervention and prevention must include both a clinical and community focus, and every health professional has a crucial part to play.

Protective effects of reasons for living against suicidal ideation in daily life

How do individuals resist suicidal urges in a crisis? Deterrents for suicide can be conceptualized as reasons for living (RFL), but our understanding of their protective effects is predominantly informed by cross-sectional research. We examined the protective effects of RFL on suicidal ideation (SI) in daily life in a high-risk sample. We also tested whether personality traits moderated the strength of the dynamic RFL-SI link. Adults with a borderline personality disorder diagnosis (N = 153, n_{suicide attempters} = 105) completed a 21-day ambulatory assessment protocol. Daily endorsements of RFL were negatively linked to SI at the within-person but not the between-person level. Whereas suicide attempters endorsed RFL less frequently than non-attempters, the protective effect of RFL was undiminished in this group. Furthermore, RFL's protective effect was particularly pronounced in those with higher average levels of suicidal ideation. While people high on extraversion endorsed RFL more often, this increase was not protective against SI, indicating that RFL reflect heterogeneous underlying psychological processes, only some of which protect against SI.

Developing a nomogram for predicting the depression of senior citizens living alone while focusing on perceived social support

BACKGROUND

Although the number of senior citizens living alone is increasing, only a few studies have identified factors related to the depression characteristics of senior citizens living alone by using epidemiological survey data that can represent a population group.

AIM

To evaluate prediction performance by building models for predicting the depression of senior citizens living alone that included subjective social isolation and perceived social support as well as personal characteristics such as age and drinking.

METHODS

This study analyzed 1558 senior citizens (695 males and 863 females) who were 60 years or older and completed an epidemiological survey representing the South Korean population. Depression, an outcome variable, was measured using the short form of the Korean version CES-D (short form of CES-D).

RESULTS

The prevalence of depression among the senior citizens living alone was 7.7%. The results of multiple logistic regression analysis showed that the experience of suicidal urge over the past year, subjective satisfaction with help from neighbors, subjective loneliness, age, and self-esteem were significantly related to the depression of senior citizens living alone (P < 0.05). The results of 10-fold cross validation showed that the area under the curve of the nomogram was 0.96, and the F1 score of it was 0.97.

CONCLUSION

It is necessary to strengthen the social network of senior citizens living alone with friends and neighbors based on the results of this study to protect them from depression.

Risk factors for suicide in psychiatric emergency patients in Beijing, China: A large cross-sectional study

Psychiatric emergency patients constitute a population at high risk of suicidal thoughts and behaviors (STB). However, the risk factors for STB in this population have not been clearly defined. This study aimed to explore the risk factors for STB in psychiatric emergency patients in China. A cross-sectional analysis was conducted at the emergency department of psychiatry, Anding Hospital, Capital Medical University from 2015 to 2017. The Chinese suicide risk factors scale was used to test the STB of the patients. Multivariable logistic regression analysis was used to determine the risk factors of STB. A total of 12,345 patients were included. Their average age was 36 years. According to the suicide risk scale, 3436 cases (27.83%) were at risk of STB, mainly young adults. The multivariable analysis showed that urban residence, years of education, living in Beijing, ethnic Han, living alone, unemployment, poor relationship with parents, one or more siblings, visit time in the night, family history, disease course, total duration, the total number of psychiatric hospitalizations, a clear diagnosis, Brief Psychiatric Rating Scale total score ≥28.5, Hamilton Depression Rating Scale total score ≥20, and Young Mania Rating Scale total score ≥12 were independent risk factors for STB.

Impacts on and Care of Psychiatric Patients during the Outbreak of COVID-19

The outbreak of coronavirus disease (COVID-19) in December 2019 has led to massive lifestyle, economic, and health changes. The COVID-19 pandemic has had broad impacts on psychiatric patients, exacerbating symptoms such as psychosis, depression, and suicidal ideation. Therefore, we aimed to review the psychological impacts of COVID-19 on psychiatric patients and mental healthcare staff and provide practical guidance for medical staff and authorities.

The main findings of this review included the impacts of COVID-19 on psychiatric patients and mental health professionals as well as the transformation of mental health care. Greater consideration should be given to the care of patients with psychosis and depression because of their lack of self-care ability, neurocognitive impairment, and impaired immune function. Depressive symptoms can be exacerbated due to several factors, such as economic crises, social isolation, and limited physical activity. Unemployment and financial problems can lead to an increased suicide rate. Consequently, mental healthcare workers’ workload can increase, which could lead to burnout and psychological symptoms such as insomnia, depression, and anxiety.

A transformation of psychiatric care is needed during the time of the pandemic. While emergency care should be maintained, outpatient care should be limited to decrease viral spread. Shifting care to telemedicine and community-based psychiatry can be helpful. Inpatient services should be adapted by tightening admission criteria, shortening the length of hospital stays, suspending some group activities, limiting visitors, and preparing for quarantine if necessary. Mental healthcare workers can be supported with telecommunication, appropriate work shifts, alternative accommodations, and good communication between the team leader and staff.

Emotion dysregulation acts in the relationship between vulnerable narcissism and suicidal ideation

Suicide behaviors are peculiar aspects of several cluster B disorders, including Narcissistic Personality Disorder. To date, it is still unclear which facet of narcissism is more related to the desire to die and which other factors are involved in this relationship. This study aims to offer preliminary empirical evidences concerning the relationship between narcissism, emotion dysregulation and suicide ideation. We administered the Pathological Narcissism Inventory (PNI), Difficulties in Emotion Regulation Scale (DERS), PID‐5‐BF (Personality Inventory for DSM‐5‐Short Form) and Beck Scale for Suicide ideation (BSI) to a sample of individuals with suicide ideation (n = 70) and a sample of community participants (n = 154). Controlling for age, gender and Negative Affectivity, we found that BSI scores correlated significantly with the vulnerable dimension of narcissism, but not with the grandiose one, and with all DERS dimension, apart from Awareness. Nevertheless, emotion dysregulation moderates the relationship between vulnerable narcissism and suicide ideation. Suicide ideation seems to be deeply connected with the vulnerable dimension of pathological narcissism and the relationship between the constructs is totally mediated by emotion dysregulation. Future directions and clinical implications are discussed.

Suicidal behaviour in older age: A systematic review of risk factors associated to suicide attempts and completed suicides

In older age, several observational studies investigated risk factors for suicide attempts/completed suicides; however, contrasting evidence came from population-based setting. In the present systematic review, we described through a narrative synthesis the significant associations existing among risk factors and suicide attempts/completed suicides in subjects aged >65 years. From the 39 population-based studies selected in six different databases until February 15, 2021, we analyzed the most frequent 28 risk factors for suicidal behaviour. The risk factors more associated to suicide attempts than other variables frequently related to suicidal behavior in older age were: depressive disorders, methods employed to self-harm (particularly poisoning), and psychotropic drug utilization followed by psychological factors and disability. Moreover, male sex, violent methods to self-harm, any psychiatric disorder (depression, anxiety and bipolar disorders), a poor medical condition, stressors/bereavement, and living alone appeared to be more significant for predicting completed suicides in late life. In older age, efforts for suicide prevention should be based on strategies to assess and treat psychiatric disorders along with psychological interventions, particularly in males.

A lifetime of challenges: real-life decision outcomes in early- and late-onset suicide attempters

BACKGROUND

People who have attempted suicide display suboptimal decision-making in the lab. Yet, it remains unclear whether these difficulties tie in with other detrimental outcomes in their lives besides suicidal behavior. We hypothesize that this is more likely the case for individuals who first attempted suicide earlier than later in life.

METHODS

A cross-sectional case-control study of 310 adults aged ≥ 50 years (mean: 63.9), compared early- and late-onset attempters (first attempt < 55 vs. ≥ 55 years of age) to suicide ideators, non-suicidal depressed controls and non-psychiatric healthy controls. Participants reported potentially avoidable negative decision outcomes across their lifetime, using the Decision Outcome Inventory (DOI). We employed multi-level modeling to examine group differences overall, and in three factor-analytically derived domains labeled Acting Out, Lack of Future Planning, and Hassles.

RESULTS

Psychopathology predicted worse decision outcomes overall, and in the more serious Acting Out and Lack of Future Planning domains, but not in Hassles. Early-onset attempters experienced more negative outcomes than other groups overall, in Lack of Future Planning, and particularly in Acting Out. Late-onset attempters were similar to depressed controls and experienced fewer Acting out outcomes than ideators.

LIMITATIONS

The cross-sectional design precluded prospective prediction of attempts. The assessment of negative outcomes may have lacked precision due to recall bias.

CONCLUSIONS

Whereas early-onset suicidal behavior is likely the manifestation of long-lasting decision-making deficits in several serious aspects of life, late-onset cases appear to function similarly to non-suicidal depressed adults, suggesting that their attempt originates from a more isolated crisis.

Attachment anxiety, depression, and perceived social support: a moderated mediation model of suicide ideation among the elderly

OBJECTIVES

Issues concerning the association among attachment anxiety, depression and suicidal ideation among the elderly have rarely been explored. The present study investigated the relationship among attachment anxiety, depression and perceived support concerning suicidal ideation among older people.

DESIGN

Cross-sectional study.

SETTING

Tertiary care settings.

PARTICIPANTS

The authors recruited 191 elderly patients from 10 tertiary care settings in Thailand.

MEASUREMENTS

Participants provided data on their suicidal ideation and suicidal attempt using Module C of the Mini-International Neuropsychiatric Interview. Their attachment anxiety was assessed using the revised Experience of Close Relationship questionnaire (ECR-R-18), while their level of depression was investigated using the Geriatric Depression Scale. In addition, their perception of being supported was ascertained using the Multidimensional Scale of Perceived Social Support. We performed two mediation analyses and moderation analyses separately using the product of coefficients approach. First, we created a mediation model to examine the role of attachment anxiety and depression on suicidal ideation. Second, a moderated mediation model was created to explore the relationship of perceived social support as a moderator of depression.

RESULTS

We found that depression significantly mediated the association between attachment anxiety and suicidal ideation. The association between depression and suicidal ideation was moderated by the level of perceived social support.

CONCLUSION

Findings of this study may broaden our understanding of how suicidal ideation develops among the elderly and further stimulate future research exploring the interaction of positive and negative factors of suicidality among the elderly. Implications of the findings were also discussed.

The Interaction of Personality and Social Support on Prospective Suicidal Ideation in Men and Women With Late-Life Depression

OBJECTIVE

Evidence suggests a cross-sectional association between personality traits and suicidal ideation in LLD. Yet, it is unclear how personality may influence suicidal ideation over time in LLD, or whether such an association would be moderated by psychosocial and biological individual differences. The present study had three aims: 1) to examine whether personality traits increase suicidal ideation in LLD over time, 2) to understand whether this relationship is influenced by subjective social support, and 3) to determine whether the potential relationship between social support, personality, and suicidal ideation is different for men and women.

DESIGN

Participants were enrolled in the Duke University Neurocognitive Outcomes of Depression in the Elderly (NCODE), a longitudinal investigation of the predictors of poor illness course in LLD. Patients were initially enrolled in the NCODE study between December 1994 and June 2000 and were followed for an average of six years.

SETTING

NCODE operates in a naturalistic treatment milieu.

PARTICIPANTS

One hundred twelve participants aged 60 and older with a current diagnosis of major depressive disorder.

MEASUREMENTS

Annual assessments of depression, suicidal ideation, and social support (measured with the Duke Social Support Index). Participants also completed the NEO Personality Inventory-Revised (NEO-PI-R) providing measures of the five major personality dimensions (neuroticism, extraversion, openness, conscientiousness, and agreeableness).

RESULTS

Univariate logistic generalized linear mixed modeling (GLMM) analyses revealed that higher levels of depression at baseline, less subjective social support, higher neuroticism, and lower extraversion were significantly associated with an increased likelihood of suicidal ideation over time. While the relationship between these dimensions and suicidal ideation were no longer significant in multivariate analyses, there was a significant moderating effect of social support on the association between suicidal ideation and certain neuroticism and extraversion personality facets. Decreased subjective social support was associated with an increased likelihood of suicidal ideation in LLD patients with high (but not low) impulsiveness and low (but not high) gregariousness and positive emotions. Across all models, social support was beneficial to women, but not men, in decreasing the likelihood of future suicidal ideation.

CONCLUSION

Changes in social support may contribute to suicidal ideation in older depressed adults with certain personality traits. Irrespective of personality traits, changes in social support had a significant effect on the suicidal ideation of women but not men. These relationships were apparent even when controlling for depression severity, age, and history of suicide attempt.

The Cost of Being Apart: The Contribution of Perceived Burdensomeness and Thwarted Belongingness to Suicide Ideation Among Israeli Older Adults

Older adults have the highest suicide rates of all age groups in most industrialized countries. However, research concerning psychological risk factors for suicide among older adults is sparse. Thus, our study aimed to examine the contribution of perceived burdensomeness (PB) and thwarted belongingness (TB) to suicide ideation (SI) among older adults. Participants included 160 Israeli older adults (aged 65-91 years), who completed measures of suicide risk, PB, and TB as well as hopelessness and depression. Using hierarchical regression, we found that PB and TB accounted for 9.8% of the variance in SI and that the interaction of PB and TB had a significant unique contribution to SI among the participants, beyond the effect of hopelessness and depression. The study's findings highlight the contribution of interpersonal variables to SI among older adults and suggest that mental health professionals should be aware of PB and TB levels when assessing suicide risk among older adults.

The therapeutic effect of repetitive transcranial magnetic stimulation in elderly depression patients

BACKGROUND

Depression, a common psychiatric disorder in elderly, serves as a remarkable precipitating factor for suicide among the elderly people. Here, a randomized double-blinded study was performed to investigate the efficacy of repetitive transcranial magnetic stimulation (rTMS) on improving the clinical symptoms and reducing suicidal ideation in elderly patients with depression.

METHODS

In this study, 103 elderly patients with depression and suicidal ideation were randomly divided into 2 groups, 48 cases in the rTMS group and 55 cases in the control group (sham rTMS). Both groups received routine drug therapy with rTMS or sham rTMS. The patients received evaluation by Hamilton depression scale and self-rating idea of suicide scale before treatment and after 2 and 4 weeks of treatment, respectively.

RESULTS

The measurement from the present study demonstrated that Hamilton depression scale and self-rating idea of suicide scale scores decreased to varying degrees in the 2 groups after treatment, and the decrease was more significant in rTMS group. The rate of marked effectiveness was much higher in rTMS group after 2 weeks of treatment compared with the control group. Furthermore, the rate of moderate effectiveness at 4 weeks after treatment was significantly higher in rTMS group compared with the control group.

CONCLUSION

Together, the present study shows that rTMS with routine drug therapy exhibited effect with quick onset to improve the clinical symptoms and reduce suicidal ideation in elderly patients with depression.

Clinical validation of the nursing diagnosis risk for suicide in the older adults

OBJECTIVE

To clinically validate risk factors for the nursing diagnosis risk for suicide in older adults.

METHODS

Case-control study (105 older adults). The strength of the association between variables was assessed using odds ratio (OR). Risk factors were grouped into hierarchical blocks according to the Integrated Motivational-Volitional Model of Suicidal Behaviour.

RESULTS

Anxiety; guilt; divorce; hostility; inability to express feelings; loss of important relationship; financial problems; apathy; low self-esteem; hopelessness; dependence and functional incapacity; unhappiness; failure; frustration; marked change in attitude and behavior; sadness; self-neglect; stockpiling medication; depression; ideation and suicidal plans; and mental disorders were associated with risk for suicide.

CONCLUSIONS

It is expected that this study will contribute to clinical nursing practice by the identification of this diagnosis in a safer and more precise manner. Descriptors: clinical judgment, nursing diagnosis, psychiatric nursing, suicide, older adult.

Association between personality traits and suicidality by age groups in a nationally representative Korean sample

Suicide is a leading health issue, which substantially contributes to the causes of death worldwide. Personality traits are some of the major risk factors for suicidality. We sought to identify the relationships between personality traits and suicidality by age group.The Big-Five Inventory-10 traits were measured in community-dwelling individuals in a nationally representative sample in the Republic of Korea. Because personality traits are long-standing patterns throughout one's lifetime, suicidality was measured based on lifetime history, rather than in a recent period. To comprehensively examine independent influences of personality traits on suicidality, psychiatric comorbidity and sociodemographic data were adjusted for.A total of 6022 subjects (3714 females and 2308 males) were included. Agreeableness (odds ratio (OR) [95% confidential intervals (CI)] = 0.79 [0.64-0.98]) was negatively associated with suicidal ideation, whereas neuroticism (1.27 [1.05-1.54]) and openness (1.36 [1.11-1.67]) were positively associated with suicidal ideation among young adults. Openness (1.25 [1.10-1.43]) had a positive association, and conscientiousness (0.86 [0.75-0.98]) had a negative association with suicidal ideation among the middle-aged group. Neuroticism is the only influencing factor for suicidal attempts among the young adult (1.88 [1.24-2.86]) and older (1.65 [1.24-2.20]) groups.Given the differential associations between personality traits and suicidality by age groups, future studies are needed to comprehensively identify possible roles of personality in suicide by age.

Personality of late- and early-onset elderly suicide attempters

OBJECTIVES

While suicidal behavior often manifests in adolescence and early adulthood, some people first attempt suicide in late life, often with remarkable lethal intent and determination. Given these individuals' more adaptive functioning earlier in life, they may possess traits that hinder adjustment to aging, such as high conscientiousness, rather than impulsive-aggressive traits associated with suicidal behavior in younger adults.

METHODS

A cross-sectional case-control study was conducted in older adults aged ≥50 (mean: 65), divided into early- and late-onset attempters (age at first attempt ≤ or >50, mean: 31 vs 61), suicide ideators as well as non-suicidal depressed and healthy controls. Personality was assessed in terms of the five-factor model (FFM, n = 200) and five DSM personality disorders analyzed on the trait level as continuous scores (PDs, n = 160). Given our starting hypothesis about late-onset attempters, the FFM dimension conscientiousness was further tested on the subcomponent level.

RESULTS

All clinical groups displayed more maladaptive profiles than healthy subjects. Compared to depressed controls, higher neuroticism, and borderline traits characterized both suicide ideators and early-onset attempters, while only early-onset attempters further displayed lower extraversion and higher antisocial traits. Late-onset attempters were similar to depressed controls on most measures, but scored higher than them on orderliness, a conscientiousness subcomponent.

CONCLUSIONS

While neuroticism, introversion, and cluster B traits are prominent in early-onset suicidal behavior, late-onset cases generally lack these features. In contrast, higher levels of orderliness in late-onset suicidal behavior are compatible with the age-selective maladjustment hypothesis. Key points Personality of elderly attempters differed between those with early- and late-onset first attempts. Early-onset attempters possessed personality traits generally found in younger suicidal populations (high neuroticism, low extraversion, antisocial, and borderline PD traits), supporting that constitutional suicide risk factors persist into late life in some individuals. Late-onset suicide attempters had higher levels of orderliness than non-suicidal depressed participants, suggesting that this generally adaptive trait may facilitate suicidal behavior in a subset of depressed elderly.

Social Interactions among Older Adults Who Wish for Death

Objectives: When the need for relatedness is frustrated, some older adults feel that life is not worth living and wish for death (WD). The aim of this study was to look at the perception of social interactions among older adults who express the WD.Methods: A probabilistic sample of 2787 French-speaking community-dwelling older adults aged 65 to 96 years (M = 73.8) took part in the Seniors Health Survey, a study on the prevalence of mental disorders which also collected information on various demographic and social variables.Results: Results showed that 5% of participants expressed WD. Participants who WD felt significantly more isolated and in conflict with their children than participants without WD. When sociodemographic variables, self-rated physical health, and depression were controlled, three social variables predicted WD in a logistic regression: being distant toward others, dissatisfaction with social life, and a lack of participation in organizations.Conclusions: Results of the present study support the interpersonal theory of suicide, which suggests that self-reported thwarted belongingness can foster WD.Clinical implications: Clinicians should consider social dissatisfaction and withdrawal as risk factors for WD and design interventions that foster social skills or meaningful connections.

Predictors of Passive and Active Suicidal Ideation and Suicide Attempt Among Older People: A Study in Tertiary Care Settings in Thailand

PURPOSE

This study compared predictors of passive suicidal ideation (SI), active SI, and suicide attempt (SA) among elderly Thai patients in tertiary care settings.

PATIENTS AND METHODS

Psychiatric diagnoses and suicidality of 803 older people were assessed using the Mini-International Neuropsychiatric Interview and the Structured Clinical Interview for DSM-IV-TR. All participants completed the Montreal Cognitive Assessment, multidimensional scale of perceived social support (MSPSS), 15-item Thai geriatric depression scale (TGDS-15), 10-item perceived social scale and the Core Symptoms Index. The chi-square test, t-test and ANOVA were used for bivariate analysis of predictors of specific suicidality types. Multiple logistic regression was used to determine the predictors for each type of suicidality.

RESULTS

The patients' mean age was 69.24 ± 6.90 years, and the majority were female (69.74%). Passive SI, active SI and SA were found among 20.42%, 3.74% and 2.37%, respectively, of the patients. Major depressive disorder (MDD) was a predictor of both passive and active SI (OR = 2.06 and 3.74, respectively). Other predictors of passive SI included hypomania (OR = 8.27) and positive score on the TGDS-15 (OR = 1.29). Predictors of active SI included agoraphobia (OR = 6.84) and hypomania (OR = 7.10). Predictors of SA included a family history of alcohol dependence (OR = 14.16), a history of depression (OR = 4.78) and agoraphobia (OR = 19.89). Surprisingly, hypertension and self-reported anxiety symptoms were protective factors for passive SI (OR = 0.51 and 0.85, respectively). Likewise, MSPSS was a protective factor for SA (OR = 0.90).

CONCLUSION

Predictors of each type of suicidality differed. MDD was the main predictor for SI; however, agoraphobia and poor perceived social support were more pronounced among individuals with SA. Further investigation, especially in longitudinal fashion, should be warranted.

Familial and social transmission of suicidal behavior in older adults

BACKGROUND

Both biological and social mechanisms have been implicated in the transmission of suicidal behavior in younger and middle-aged adults. Yet, while suicide rates rise with age, it is not clear whether such mechanisms operate in late life. Thus, we looked for evidence of social and familial suicidal transmission in elderly with late- vs. early-onset suicidal behavior by examining exposure to suicidal behavior within biological relatives and broader social networks.

METHOD

Participants were 356 adults, aged 50 or older (mean: 67), divided into five groups: early-onset suicide attempters (first lifetime attempt before age 60), late-onset attempters, suicide ideators (without attempt history), depressed non-suicidal controls, and non-psychiatric controls. History of suicidal behavior in one's biological relatives and friends/unrelated kin was assessed via clinical interview, and group differences were examined via generalized linear mixed-effects models.

RESULTS

There was a main effect of group (χ²₄ = 18.38, p < 0.001) such that familial or social exposure to suicidal behavior was more prevalent in early- than late-onset attempters. Late-onset attempters' exposure was similar to non-suicidal groups'. However, there was no significant group by relationship interaction, indicating that suicidal behavior was not significantly more prominent among the biological relatives of either attempter group.

LIMITATIONS

Participants' report of exposure is subject to awareness and recall biases.

CONCLUSION

Suicidal clustering in biological relatives and friends/unrelated kin is associated with early-, but not late-onset suicidal behavior in older adults. Suicidal transmission in older adults follows a pattern of familial and social clustering suggestive of social transmission.

National study of emergency department disposition for high suicide risk geriatric patients

OBJECTIVE

To examine predictors of hospitalization among older adults at high risk for suicide treated in emergency departments (EDs).

METHODS

This retrospective cohort analysis used national 2015 Medicare claims for adults ≥65 years with ED visits for suicide ideation or deliberate self-harm (N = 50,472) merged with data from the Area Health Resource File. Rates and adjusted risk ratios (ARR) of hospital admission were assessed.

RESULTS

A majority of ED episodes resulted in hospital admission (81.9%) with most being admitted to a psychiatric unit (62.8%). Visits for self-harm with suicide ideation were most likely to result in hospitalization (94.7%) compared to suicide ideation alone (84.0%) or self-harm alone (73.1%). Current diagnosis of depression, bipolar, anxiety, cognitive, and personality disorder were associated with hospitalization. Co-occurring mental and substance use disorders were the most predictive mental health condition of admission. Overall, severity of current medical comorbidity was the strongest predictor of hospital admission.

CONCLUSIONS

Most older adults treated in EDs for suicide ideation or self-harm are hospitalized. Medical morbidity plays a more prominent role than other patient factors in admission status.

Evidence-Based Practice Guideline: Secondary Prevention of Late-Life Suicide

Suicide is a tragic, traumatic loss, and one of the most emotionally devastating events families, friends, and communities experience. Suicide claims more than 800,000 lives every year, and some of the highest rates of suicide in the United States and globally are among older adults. The purpose of this evidence-based guideline is to help health care providers recognize those at risk for suicide and recommend appropriate and effective secondary suicide prevention interventions. The information in this guideline is intended for health care providers who work in a variety of settings, including hospitals, nursing homes, rehabilitation centers, out-patient clinics, mental health clinics, home health care, and other long-term care facilities. Assessment and preventive treatment strategies were derived by exhaustive literature review and synthesis of the current evidence on secondary prevention of late-life suicide across practice settings.
