Health conditions, physical disabilities, perceived burdensomeness, and depressive symptoms influence suicidal ideation

Disability and Suicidal Ideation among Indigenous Adults in Canada: Cultural Resources as Contingencies

OBJECTIVES

The present study asks: Is disability associated with suicidal ideation among Indigenous adults in Canada? And if so, do cultural resources-as measured by cultural identity affect, cultural group belonging, cultural engagement, and cultural exploration-modify this association?

METHODS

Data were from a nationally representative sample of First Nations peoples living off-reserve, Métis, and Inuit across Canada-the 2017 Aboriginal Peoples Survey (N = 16,125). A series of weighted logistic regression models were performed.

RESULTS

Indigenous adults with disabilities were significantly more likely than those without disabilities to report suicidal ideation, even after controlling for socio-demographic characteristics and physical and mental health conditions. At the same time, people with multiple disabilities were at greater risk for suicidal ideation, with the largest association among those with five or more disabilities. Furthermore, the detrimental association between disability status and suicidal ideation attenuated among those who reported cultural group belonging. In a similar vein, the buffering role of cultural group belonging was also observed in the association between the number of disabilities and suicidal ideation.

CONCLUSIONS

This study provides compelling evidence that disability is a risk factor for suicidal ideation among Indigenous adults and that cultural group belonging plays a stress-buffering role in this relationship.

Network analysis of comorbid depression, suicidality and biomarkers on HPA axis among mood disorder patients to psychiatric emergency services

Rapid assessment and intervention of suicide risk are common and challenging in psychiatric emergency departments (PED). It is unclear whether distinct pathophysiological processes exist among depressive patients with suicidality. This study examined the network structures of biomarkers on Hypothalamic-Pituitary-Adrenal (HPA) axis, such as Adrenocorticotropic hormone (ACTH) and Corticosterone (Cort), as well as suicidality and depressive symptoms in mood disorder patients in PED. Mood disorder patients in PED were assessed with the measurements of suicidality and depressive symptoms, respectively. A network analysis was performed to identify central symptoms and bridge symptoms of this network and their links to ACTH and Cort. Network stability was examined using the case-dropping procedure. The Network Comparison Test (NCT) was conducted to evaluate whether network characteristics differed by gender. A total of 1815 mood disorder patients were recruited. The prevalence of SI was 31.2% (95% CI: 28.15-34.21%), SP was 30.4% (95% CI: 27.39-33.41%), SA was 30.62% (95% CI: 27.61-33.64%) among psychiatric outpatients. The mean score of HAMD-24 was 13.87 ± 8.02. Network analysis revealed that 'Somatic anxiety' had the highest expected centrality, followed by 'Hopelessness' and 'Suicide attempt'. 'Corticosterone' and 'Retardation' may be the main bridge symptoms between depressive symptoms and the suicidality community. The network model showed a high degree of stability. Gender did not significantly influence the network structure. The central symptoms and key bridge symptoms identified could be potential targets for interventions of the HPA axis, which is designed for regular screening of a range of suicidal activity. In the light of this, timely treatment should be provided for psychiatric emergency care.

Differences in suicide risk correlates and history of suicide ideation and attempts as a function of disability type

BACKGROUND

Disability status is associated with correlates of suicide risk (perceived burdensomeness, thwarted belongingness, negative future disposition, felt stigma, suicidal ideation, and suicide attempts).

AIMS

This study aimed to examine whether suicide-related correlates differ significantly as a function of disability type.

METHODS

Individuals with mobility and vision disabilities (N = 102) completed semistructured interviews and online-based questionnaires. Analysis of variance/analysis of covaiance and Fisher's exact tests were conducted to examine whether mean levels of suicide-related correlates differed significantly between individuals with blindness/low vision (n = 63) versus mobility-related (n = 39) disabilities.

RESULTS

No significant between-group differences were observed for most outcomes; however, individuals with vision disabilities reported higher mean levels of felt stigma and positive future disposition than those with mobility-related disabilities.

LIMITATIONS

The limited representation of disabilities among participants precludes generalization to individuals with other forms of disability and the cross-sectional design prevents inference about causality.

CONCLUSIONS

Interventions targeting cognitive processes that underlie suicide risk may be applicable to people with mobility and vision disabilities.

The Association of Opioid Misuse and Suicidality among People with Disabilities

Background/Purpose: Past research has linked non-medical prescription opioid use (NMPOU) with suicide, though less focus has been placed among people with disabilities impacted by the opioid epidemic. This study examined the relationship of NMPOU and suicidality among people with and without disabilities while controlling for sociodemographic and other variables. Method: Using the 2019 National Survey on Drug Use and Health, weighted logistic regression analyses were conducted on a cross-sectional sample of 38,088 respondents 18 and older to examine the effect of opioid misuse and disability on serious thoughts of suicide, having a suicide plan, and making a suicide attempt. Results: Findings indicated opioid misuse was associated with 37% higher odds for having a suicide plan in the past year (OR = 1.37, p < .05). The main results indicated the people with disabilities had 30% higher odds for having a suicide plan (OR = 1.30, p < .05) and 73% higher odds for a suicide attempt in the past year (OR = 1.73, p < .001). Interaction analysis found that opioid misuse was associated with higher odds for having a suicide plan (OR = 1.89, p < .01), and having a suicide attempt among those with disabilities (OR = 2.57, p < .01). Conclusion: Results indicated that opioid misuse is a risk factor for suicide, and people with disabilities were at greater risk. Health workers can serve as a nexus point in effectively engaging at-risk people with disabilities in substance use and mental health prevention and recovery services.

Association between functional disability type and suicide-related outcomes among U.S. adults with disabilities in the National Survey on Drug Use and Health, 2015-2019

While research on suicidal behavior for people with disability (PWD) suggests they experience higher risk than people without disability, less is known about variations among individuals with different disability types. This nationally representative, cross-sectional study compared differences in suicide-related outcomes (ideation, planning, attempts) among PWD by functional disability type (hearing, vision, cognitive, mobility, complex activity) and number. Secondary analysis of adult PWD in the 2015-2019 National Survey on Drug Use and Health (unweighted N = 35,544; representing 47,723,378 PWD, weighted) was used to estimate relationships between suicide-related outcomes and disability type and number. Most respondents were female (55.9%), and 36.0% were aged ≥65 years. Adjusted odds ratios (AORs) from multivariable logistic regression indicated that suicidal ideation and suicide attempt, respectively, were significantly more likely among individuals with cognitive (AOR = 1.71, 95% CI = 1.24-2.35; AOR = 2.54, 95% CI = 1.31-4.91), complex activity (AOR = 1.96, 95% CI = 1.37-2.81; AOR = 2.67, 95% CI = 1.32-5.41), and ≥2 limitations (AOR = 2.02, 95% CI = 1.52-2.69; AOR = 3.46, 95% CI = 1.84-6.50) than hearing limitation. Also, relative to other disability types, suicide-related outcomes were significantly more likely among individuals with cognitive limitation and complex activity limitation (p < 0.001). Additionally, suicide-related outcomes elevated in likelihood as the number of limitations increased, with the largest associations among those with ≥5 limitations for suicidal ideation (AOR = 2.31, 95% CI = 1.46-3.66), suicide planning (AOR = 3.34, 95% CI = 1.97-5.68), and suicide attempt (AOR = 6.37, 95% CI = 3.76-10.79). Subgroup analyses showed that presence of cognitive limitation and multiple limitations differentiated between suicidal ideators and suicide attempters. Further research is needed to identify causes of these risks and develop suicide prevention efforts for these particularly vulnerable groups.

Association Between Disability and Suicide-Related Outcomes Among U.S. Adults

INTRODUCTION

Although research has analyzed the sociodemographic and socioeconomic risks for suicide, only recently has suicide risk for people with disabilities been examined. This study investigates the associations between disability and distinct suicide-related outcomes, including suicidal ideation, suicide planning, and suicide attempt.

METHODS

This nationally representative, cross-sectional study comprised secondary analyses of the 2015-2019 National Survey on Drug Use and Health conducted in 2020 (N=198,640, representing 229,556,289 U.S. adults). Disability status comprised the presence of any disability; hearing, vision, mobility, cognitive, complex activity, or ≥2 limitations; and 1, 2, 3, 4, or ≥5 limitations. Suicide-related outcomes in the past year included none, suicidal ideation only, suicide planning, and suicide attempt. Multivariable logistic regression was applied to estimate the AORs.

RESULTS

Overall, 19.8% reported any disability. Results showed that people with disabilities were significantly more likely than those without disabilities to report suicidal ideation (AOR=2.13, 95% CI=1.93, 2.36), suicide planning (AOR=2.66, 95% CI=2.27, 3.11), and suicide attempt (AOR=2.47, 95% CI=2.05, 2.98). Furthermore, individuals within each limitation count group were significantly more likely than people without disabilities to report suicide-related outcomes (p<0.001), with the largest magnitudes among those with ≥5 limitations for suicidal ideation (AOR=3.80, 95% CI=2.32, 6.23), suicide planning (AOR=6.45, 95% CI=3.52, 11.80), and suicide attempt (AOR=8.19, 95% CI=4.45, 15.07).

CONCLUSIONS

People with various types of functional disabilities had an elevated risk for suicide-related outcomes, compared with people without disabilities. The more limitations a person had progressively increased their risk. These findings call for focused attention to the mental health of people with disabilities, including suicide prevention efforts that accommodate their needs.

Examining the role of stigma and disability-related factors in suicide risk through the lens of the Interpersonal Theory of Suicide

Research has largely not identified processes contributing to the relationship between physical disability and suicide risk. This cross-sectional research is aimed at examining the associations among felt stigma, perceived burdensomeness, disability severity, and perceptions about future suicidal ideation and attempts. Adults (N = 127) with physical disabilities recruited through online and printed advertisements completed self-report measures and semi-structured interviews. We anticipated that felt stigma would be associated with individuals' perceived likelihood of future suicidal ideation and attempts indirectly through perceived burdensomeness, and that these relationships would be moderated by the impact of disability on three important life domains. Results from a series of moderated mediation analyses partially supported study hypotheses and indicated indirect relationships of stigma to suicide-related perceptions. However, disability severity in the three examined domains did not moderate these indirect relationships. Felt stigma and perceived burdensomeness may contribute to self-perceptions of suicide risk among individuals with physical disabilities.

Domains of Functional Impairment and Their Associations with Thwarted Belonging and Perceived Burden in Older Adults

Objectives: Functional impairment and social disconnection are risk factors for suicide in later life. This paper examines associations between domains of functional impairment and two forms of social disconnection that are empirically linked to suicide in later life - low (or thwarted) belonging and perceived burden on others.Methods: Participants are 62 older primary care patients (67.68% female, mean age = 72.05) who endorsed feeling lonely or like a burden. Participants completed self-report measures of low belonging and perceived burden (INQ-R) and domains of functional impairment (WHODAS 2.0) at a single time point.Results: Greater perceived burden was associated with greater impairment in activities of daily living ("self-care"), while greater thwarted belonging was associated with greater impairment in social functioning, when controlling for depressive symptoms and age. Domains of mobility, cognition and social participation were not associated with either belonging or perceived burden.Conclusions: Impairment in self-care (ADLs) and social functioning may be more strongly associated with perceived burden and thwarted belonging than other domains of functional impairment.Clinical Implications: Considering specific domains of functional impairment - rather than functioning more broadly - may facilitate tailored interventions to target suicide risk.

Psychopathic personality traits as a form of dispositional capability for suicide

The capability to enact lethal self-harm has recently been highlighted as a critical risk factor for suicidal behavior. Klonsky and May's (2015) three step theory of suicide (3ST) expanded upon the construct of the capability for suicide by dividing it into categories: dispositional, acquired, and practical. The current study examined constructs of Patrick and colleagues' (2009) triarchic model of psychopathy as indicators of dispositional capability in gun owners, a sample at heightened risk for death by suicide (Anestis and Houtsma, 2017). We anticipated that specific psychopathic traits would exhibit robust associations with other components of the capability for suicide. In a sample of 300 gun-owning adults, Boldness was uniquely related to all indicators of practical capability in both male and female gun owners, and a Boldness*Meanness interaction predicted the highest levels of some capability components. These results are consistent with theoretical conceptualizations of the triarchic model. Our findings indicate that, among US gun owners, dispositional factors may impact comfort with and aptitude with guns, which may enhance our understanding of which gun owners are at the greatest risk of gun suicide should they develop suicidal thoughts.

Physical disability and suicide: recent advancements in understanding and future directions for consideration

Recent research indicates a heightened risk of suicide in this population, a concern given that suicide may be more accepted for those with physical disabilities than for those without such disabilities. The relationship between physical disability and suicide has begun to be examined within empirically supported frameworks of suicide and indicates that interpersonal factors (e.g. perceived burdensomeness) and pain are mechanisms contributing to this heightened risk of suicide. The suicide rate after acquiring a physical disability, such as a spinal cord injury, and the greater odds of suicide after reporting having a disability further support the association between physical disability and suicide. The multifaceted nature of physical disability is reflected in its relationship with suicidal ideation and behaviors.
