Perceived stops to suicidal thoughts, plans, and actions in persons experiencing psychosis

Associations of anxiety and depression with suicide experiences in individuals with and without childhood trauma: The role of social support

No studies have examined the differences and similarities between individuals with and without experiences of childhood sexual and/or physical abuse in relation to anxiety and depression severity, perceived social support, and suicide experiences. Furthermore, whether the strength of these associations differs between these two groups, and whether the buffering role of perceived social support is equally effective, remain unknown. This study, which was based on 842 British participants, aimed to address these gaps. There were three key findings: i) abused individuals reported significantly more severe depression, anxiety, and suicide experiences, and lower social support, ii) the associations between depression, anxiety, and suicide experiences did not differ between these groups, whereas the association between social support and suicide experiences was more pronounced in abused individuals, and iii) perceived social support acted as a moderator of the association between depression and suicide experiences in both groups. These findings are important because they suggest that for the individuals with childhood trauma perceptions of being less supported by their significant others may lead to suicide acts. Furthermore, perceptions of being socially supported appeared to weaken the association between depression and suicide experiences equally in individuals with and without childhood trauma.

Psychological resilience to suicidal thoughts and behaviours in people with schizophrenia diagnoses : A systematic literature review

PURPOSE

Suicide deaths are a major concern in people with schizophrenia diagnoses. However, many people with such diagnoses do not attempt suicide, nor die by suicide, suggesting that some individuals are resilient to the impact of suicide triggers. This systematic literature review aimed to (1) appraise the evidence for psychological factors which confer resilience to suicidal thoughts and behaviours, and (2) categorize these psychological factors into broader psychological constructs which characterize resilience.

METHODS

The review was conducted in accordance with the PRISMA guidelines for the reporting of systematic reviews. A literature search of four electronic databases (Web of Science, PubMed, PsycINFO, and MEDLINE) was conducted. A quality evaluation of the included studies was carried out by two independent researchers using a quality assessment tool.

RESULTS

Psychological factors from 27 studies were categorized into four constructs: (1) perceived social support, (2) holding religious and spiritual beliefs, (3) identifying reasons for living, and (4) perceived positive personal skills and attributes.

CONCLUSIONS

The limited literature showed that resilience is important in understanding suicidal thoughts and behaviours in people with schizophrenia diagnoses. There is a need for prospective research that investigates moderating effects of psychological resilience in the pathways to suicidal thoughts and behaviours in people with schizophrenia diagnoses.

PRACTITIONER POINTS

Novel evidence for four psychological constructs which may confer resilience to suicidal thoughts and behaviours in people with schizophrenia diagnoses. Strong evidence for the impact of perceived social support and appraisals of personal skills and attributes on the severity of suicidal experiences in people with schizophrenia diagnoses. There was equivocal evidence for the effect of holding religious and spiritual beliefs on suicide attempts. Clinical practice would benefit from assessing perceived personal attributes and levels of social support from significant others and health professionals.

Examining the mechanisms by which adverse life events affect having a history of self-harm, and the protective effect of social support

BACKGROUND

Psychological models of suicide emphasize perceptions of negative stressors, hopelessness and self-harm as key antecedents to suicidal thoughts/acts. Such models also emphasize the potential protective role of social support in these pathways. However, such pathways have not been tested using population level data. Hence, this study aimed to redress this gap.

METHODS

Questionnaire data regarding 24,444 patient suicide deaths were analysed. All individuals died between 1996 and 2015 and were seen by secondary mental health services in England within 12 months before their death. Mediation analyses, using fitted logistic regression models, investigated direct and indirect pathways between negative stressors, hopelessness and a proxy measure of suicide, namely, self-harm history. In addition, the buffering effects of social support were examined in these pathways.

RESULTS

There was a direct effect of negative life events on suicidal behaviors. Supporting contemporary psychological models of suicide, a mediated effect via hopelessness and a protective effect of social support were identified. Social support buffered the pathway between stressful life events and hopelessness, with hopelessness decreasing as social support increased.

LIMITATIONS

Causal inferences are inappropriate as the design was cross-sectional. A proxy measure of suicidality was utilized (history of self-harm) as all individuals had died by suicide.

CONCLUSIONS

This is the first time that population data has been used to test psychological pathways to suicidal acts involving negative stressors, hopelessness and social support. Psychological interventions should focus on increasing social support following negative life events together with ameliorating perceptions of hopelessness.

Factors that contribute to psychological resilience to suicidal thoughts and behaviours in people with schizophrenia diagnoses: qualitative study

BACKGROUND

Suicide is a leading cause of premature death in people with a diagnosis of schizophrenia. Although exposure to stressors can play a part in the pathways to death by suicide, there is evidence that some people with a diagnosis of schizophrenia can be resilient to the impact of suicide triggers.

AIMS

To investigate factors that contribute to psychological resilience to suicidal thoughts and behaviours from the perspectives of people with a diagnosis of schizophrenia.

METHOD

A qualitative design was used, involving semi-structured, face-to-face interviews. Twenty individuals with non-affective psychosis or schizophrenia diagnoses who had experience of suicide thoughts and behaviours participated in the study. The interviews were audio-recorded, transcribed verbatim and examined using inductive thematic analysis.

RESULTS

Participants reported that psychological resilience to suicidal thoughts and behaviours involved ongoing effort. This ongoing effort encompassed: (a) understanding experiences (including reconciliation to mental health experiences and seeking reasons to live), (b) active behaviours (including talking to people and keeping occupied), and (c) relationship dynamics (including feeling supported by significant others and mental health professionals).

CONCLUSIONS

Psychological resilience was described as a dynamic process that developed over time through the experiences of psychosis and the concomitant suicidal experiences. Psychological resilience can be understood using a multicomponential, dynamic approach that integrates buffering, recovery and maintenance resilience models. In order to nurture psychological resilience, interventions should focus on supporting the understanding and management of psychosis symptoms and concomitant suicidal experiences.

Suicidal ideation while incarcerated: Prevalence and correlates in a large sample of male prisoners in Flanders, Belgium

Prisoners constitute a high-risk group for suicide. As an early stage in the pathway leading to suicide, suicidal ideation represents an important target for prevention, yet research on this topic is scarce in general prison populations. Using a cross-sectional survey design, correlates of suicidal ideation while incarcerated were examined in a sample of 1203 male prisoners, randomly selected from 15 Flemish prisons. Overall, a lifetime history of suicidal ideation and attempts was endorsed by 43.1% and 20.3% of respondents, respectively. Approximately a quarter of all prisoners (23.7%) reported past-year suicidal ideation during their current incarceration, which was significantly associated with both imported vulnerabilities (psychiatric diagnoses and a history of attempted suicide) and variables unique to the prison experience (lack of working activity, exposure to suicidal behaviour by peers, and low levels of perceived autonomy, safety and social support) in the multivariate regression analysis. A first-ever period of imprisonment and a shorter length of incarceration (≤12months) were also associated with increased odds of recent suicidal ideation. Collectively, the current findings underscore the importance of both vulnerability factors and prison-specific stressors for suicidal ideation in prisoners, and hence the need for a multi-faceted approach to suicide prevention in custodial settings. In addition to the provision of appropriate mental health care, environmental interventions that target modifiable aspects of the prison regime could provide a substantial buffer for the onset and persistence of suicidal ideation in this at-risk population.

The interactive effects of negative symptoms and social role functioning on suicide ideation in individuals with schizophrenia

Findings regarding the protective effect of social role functioning on suicide ideation in individuals with schizophrenia have been mixed. One reason for such inconsistencies in the literature may be that individuals with prominent negative symptoms of schizophrenia may not experience a desire for social closeness, and therefore social role functioning may not influence suicide risk in these individuals. The aim of this study was to examine the moderating effects of self-reported desire for social closeness and interviewer-rated negative symptoms on the relationship between social role functioning and suicide ideation. Our sample consisted of 162 individuals who had been diagnosed with schizophrenia-spectrum disorders; all participants completed self-report questionnaires and clinician-administered interviews, and moderation hypotheses were tested with a non-parametric procedure. The results indicated that motivation and pleasure-related negative symptoms moderated the relationship between social role functioning and suicide ideation; self-reported desire for social closeness and negative symptoms related to expression did not have such a moderating effect. Specifically, better social role functioning was associated with less suicide ideation only in those individuals who had low motivation and pleasure-related negative symptoms; no significant relationship was observed between social role functioning and suicide ideation among those with elevated motivation and pleasure-related negative symptoms. These findings suggest that assessing for negative symptoms and social role functioning may inform suicide risk assessments in individuals with schizophrenia, and improving social role functioning may reduce suicide ideation among those with few motivation and pleasure-related negative symptoms.
