Loneliness, social isolation and suicide risk in people with psychotic disorders

Prevalence and Clinical Correlates of Suicidal Ideation and Attempts in Individuals at Clinical High Risk for Psychosis

BACKGROUND

Individuals with psychosis symptoms are at high risk for suicidal ideation and attempts. The prevalence and correlates of suicidal ideation and attempts in clinical high risk for psychosis (CHR-P) have yet to be clarified. This study reports on the prevalence and clinical correlates of suicidal ideation and attempts in a clinical CHR-P sample.

METHOD

Participants (n = 135) included CHR-P clients at a CHR-P community specialty clinic, who participated in a clinical assessment between 2017 and 2022. Assessments measured attenuated psychosis symptoms, suicidal ideation and attempts, clinical covariates, and functioning. Frequency analyses assessed the prevalence of lifetime suicidal ideation and attempts and t-test and Chi-square identified clinical correlates. Logistic regression assessed the relationship between significant clinical correlates and lifetime suicide attempts.

RESULTS

Sixty-five percent of participants at CHR-P endorsed lifetime suicidal ideation, while 22.2% reported at least one lifetime attempt. Correlates for lifetime suicidal ideation included self-reported gender expansive identity, hopelessness, depression, trauma, obsessive compulsive symptoms, insight: reflectiveness, trauma diagnoses, mood disorder diagnoses, and perceptual abnormalities/hallucinations. Significant correlates for lifetime suicide attempts included self-reported hopelessness, depression, trauma diagnosis and mood disorder diagnosis.

CONCLUSION

CHR-P clients are at a higher risk for suicidal ideation and attempts compared to the general population. Correlates of suicidal ideation and attempts may be diagnostically heterogeneous and therefore interventions should be tailored to specific clinical needs. Clients with trauma-disorder diagnoses may be at highest risk for suicidal ideation and attempts. Continued intervention and longitudinal research is needed to clarify causal risk factors and establish evidence-based treatments for suicidal ideation and attempts in CHR-P.

Social disconnection and suicide mortality among Japanese older adults: A seven-year follow-up study

BACKGROUND

Few prospective studies have examined the association between social disconnection and late-life suicide. Therefore, we conducted a large-scale prospective study of older adults in Japan to examine differences in suicide mortality according to specific aspects of social disconnectedness.

METHODS

We conducted a nationwide baseline survey of functionally independent older adults (age ≥65 years) from 12 municipalities in Japan from 2010 to 2011. We followed the participants (n = 46,144) for cause of death through December 2017 using vital statistics. Social disconnection was assessed based on the indicators of eating alone, a lack of instrumental/emotional support, no participation in community activities, and no contact with friends. We adopted Cox regression models with multiple imputation for missing values and calculated the population-attributable fraction (PAF).

RESULTS

A total of 55 suicide deaths were recorded during an average follow-up of 7 years. Older adults with social disconnection had a marginally increased risk of suicide. The hazard ratio for eating alone vs. eating together was 2.81 (95% confidence interval [CI]: 1.47-5.37). The direction of these associations and point estimations did not largely change after controlling for depressive symptoms, an evident risk factor for suicidal behavior. The PAF indicated that eating alone was attributable to around 1800 (29%) of the suicide deaths among older adults annually in Japan.

CONCLUSION

Avoidance of not only depressive symptoms, but also social disconnection including eating alone, is useful in suicide prevention among older adults.

The Impact of Complex PTSD on Suicide Risk in Patients with Bipolar Disorder: A Cross-Sectional Study

BACKGROUND

Patients with bipolar disorder (BD) are more likely than the general population to experience traumatic events, particularly during childhood, and these may predict and be a risk factor for the development of complex PTSD (cPTSD). The presence of multiple traumas plays a relevant role from a psychopathological point of view, but little is known about the effect this may have on suicide attempts in patients with BD.

METHODS

A cross-sectional study was conducted comparing socio-demographic and clinical characteristics, recruiting 344 patients diagnosed with BD I and II, screened for the presence (or absence) of cPTSD using the International Trauma Questionnaire (ITQ). Suicide attempts were assessed directly during the clinical interview and from the patient's medical record.

RESULTS

The results emerging from the study indicate that cPTSD can be considered a risk factor for suicide attempts in patients with BD. Furthermore, evidence is provided to support the idea that cPTSD is highly prevalent in patients with BD and is related to a higher psychopathological burden.

CONCLUSIONS

The results recommend an urgent and comprehensive assessment of suicidal risk in patients with comorbidity of both bipolar disorder and cPTSD. There is a crucial demand for early intervention initiatives and proactive prevention strategies to address the intricate intersection of these mental health challenges.
