Self-reported disability and quality of life in an online Australian community sample with suicidal thoughts

Associated Factors of Suicidal Behavior Among Persons with Physical Disability: A Systematic Review

Background

Suicide is common among persons with physical disabilities as they face several physical, social, psychological, and economic problems. They are at risk for suicidal thoughts, behaviors, and death by suicide. We aimed to systematically review empirically published articles and identify the associated factors of suicidal ideation and suicide attempts in persons with physical disabilities.

Methods

A systematic search was carried out on the literature published from January 1, 2000 to January 19, 2023 in PubMed, Cochrane, Web of Science, Google Scholar, Shodh Ganga, and so on. All the synonyms of keywords or MeSH terms for suicidal ideation, suicide attempt, and physical disability were used. Two hundred thirty-six articles were found, and after following inclusion and exclusion criteria, 12 remained.

Result

The associated factors of suicidal behavior were disability status (11/12 studies), burdensomeness (8/12 studies), felt stigma (4/12 studies), depressive symptoms (6/12 studies), loneliness (2/12 studies), lack of social and emotional connectedness (2/12 studies), long-term physical or mental disability (2/12 studies), congenital disability (1/12 studies), and aggression (1/12 studies).

Conclusion

Timely, evidence-based, low-cost interventions can provide great assistance and address the specific needs of this vulnerable population as they have higher risk for suicidal behavior.

Stress and alcohol-related coping mechanisms linking lifetime suicide ideation and attempt to multidimensional quality of life

BACKGROUND

Suicide ideation and attempt are linked to adverse mental health outcomes, but few studies have examined their associations with quality of life (QoL). This study examined the impact of lifetime history of suicidal ideation and attempt on four QoL domains via perceived stress and problematic drinking.

METHODS

Participants were drawn from the National Institute on Alcohol Abuse and Alcoholism Natural History Protocol (N = 1055), including those with no history of suicidality (78.6 %), suicidal ideation only (15.3 %), and a history of suicide attempt (6.2 %). Structural equation modeling (SEM) was utilized to test perceived stress and drinking as mediational pathways to multidimensional QoL.

RESULTS

Individuals with a history of suicide ideation and/or attempt reported higher perceived stress in the past month, more problematic drinking in the past year, and lower QoL domains in the past two weeks. SEM showed significant mediation effects through dimensions of perceived stress (helplessness, lack of self-efficacy) and alcohol problems. When these mediators were considered simultaneously, the mediation effects through alcohol problems were attenuated, while several direct effects of suicidality on physical, psychological, and social QoL were weakened but remained significant.

LIMITATIONS

Cross-sectional data with retrospective report of suicidality history.

CONCLUSIONS

A lifetime history of suicidality was associated with lower multidimensional QoL. These associations were partially explained by stress and alcohol-related coping mechanisms such as feeling helpless or inadequate when encountering stressors and problematic drinking. Perceived stress and drinking to cope may be important intervention targets to improve QoL among those with a history of suicidality.

The associations between depressive symptoms, functional impairment, and quality of life, in patients with major depression: undirected and Bayesian network analyses

BACKGROUND

Depressive symptoms, functional impairment, and decreased quality of life (QOL) are three important domains of major depressive disorder (MDD). However, the possible causal relationship between these factors has yet to be elucidated. Moreover, it is not known whether certain symptoms of MDD are more impairing than others. The network approach is a promising solution to these shortfalls.

METHODS

The baseline data of a multicenter prospective project conducted in 11 governances of China were analyzed. In total, 1385 patients with MDD were included. Depressive symptoms, functioning disability, and QOL were evaluated by the 17-item Hamilton Depression Rating Scale (HAMD-17), the Sheehan Disability Scale (SDS), and the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF). The network was estimated through the graphical Least Absolute Shrinkage and Selection Operator (LASSO) technique in combination with the directed acyclic graph.

RESULTS

Three centrality metrics of the graphical LASSO showed that social life dysfunction, QOL, and late insomnia exhibited the highest strength centrality. The network accuracy and stability were estimated to be robust and stable. The Bayesian network indicated that some depressive symptoms were directly associated with QOL, while other depressive symptoms showed an indirect association with QOL mediated by impaired function. Depressed mood was positioned at the highest level in the model and predicted the activation of functional impairment and anxiety.

CONCLUSIONS

Functional disability mediated the relationship between depressive symptoms and QOL. Family functionality and suicidal symptoms were directly related to QOL. Depressed mood played the predominant role in activating both anxiety symptom and functional impairment.

Disability, physical activity, and health-related quality of life in Australian adults: An investigation using 19 waves of a longitudinal cohort

Background

Any form of long-term physical or mental impairment might negatively influence health-related quality of life (HRQoL). HRQoL, as an independent concept, covers a wide range of characteristics that includes physical, mental, social, and spiritual functions. People with disabilities are continuously exposed to multiple barriers that deteriorate their HRQoL. It also creates impairment in performing physical activities. However, experts opine regular physical exercise as an intervention to help disabled people. This research aims to investigate the association between disability and physical activity with HRQoL among the adult population in Australia.

Design

A retrospective cohort study.

Methods

This study utilized the most recent 19 waves of data (2002–2020) from the nationally representative Household, Income and Labour Dynamics in Australia (HILDA) survey. Component summary scores such as physical component summary (PCS) and mental component summary (MCS), and SF-6D utility scores were utilized to measure HRQoL. Random-effects GLS regression technique was fitted to estimate the association between disability and physical activity with HRQoL, after adjusting for a range of socio-demographic and health-related characteristics.

Results

Disability was negatively associated with the PCS (-5.95), MCS (-2.70) and SF-6D (-0.060) compared with non-disabled counterparts. However, respondents engaged in the recommended level of physical activity had substantial gain in PCS (b = 0.96), MCS (1.57), and SF-6D (0.021) scores. Besides, the results showed that performing the recommended level of physical activity in the presence of disability has lessen the negative effect of disability/ positive moderating effect of physical activity on PCS, MCS, and SF-6D scores by 1.84 points, 0.82 points, and 0.013 percentage points, respectively.

Conclusion

This study found an inverse association between disability and HRQoL among Australian adults. However, physical activity was associated with improved HRQoL. Therefore, public health interventions, such as the orientation of physical activities, have a higher potential to dwindle the burden regarding HRQoL.

Specific aspects of sleep disturbance associated with suicidal thoughts and attempts

OBJECTIVE

Previous research suggests that sleep disturbance is associated with suicidal ideation and suicide attempt. However, few studies have accounted for the presence of multiple mental disorders and interpersonal factors associated with suicide risk. Furthermore, limited research has examined which aspects of sleep disturbance are most strongly associated with suicidal thoughts and attempts.

METHOD

A large community-based sample of Australian adults (n = 3,618; 81% female; 37% reporting ideation) completed a comprehensive survey assessing suicidal thoughts and behaviours, sleep disturbance, common mental disorders and interpersonal risk factors. Sleep disturbance was assessed using the 6-item PROMIS sleep disturbance scale and suicidality was measured using the Psychiatric Symptom Frequency Scale. Analyses were adjusted for age, sex, perceived burdensomeness, thwarted belongingness, and clinical caseness for six mental disorders, including major depression.

RESULTS

After accounting for mental health, demographic and interpersonal characteristics, increasing sleep disturbance was significantly associated with higher odds of both suicidal ideation (OR=1.17 for one-SD increase in PROMIS-SD), and suicide attempt (OR=1.33 for one-SD increase in PROMIS-SD). Of the specific indicators of sleep disturbance, only sleep onset (difficulties falling asleep) had a significant independent association with both suicidal ideation (p < 0.001) and suicide attempt (p = 0.047).

CONCLUSIONS

Sleep disturbance is independently associated with greater risk of suicidal thoughts and behaviours. Sleep disturbance is highly modifiable, so sleep interventions for people with suicide risk and sleep problems may provide an effective and efficient approach to suicide prevention in the community.
