Perceived burdensomeness and suicide ideation in adult outpatients receiving exposure therapy for anxiety disorders

Interpersonal Needs, Mental Pain, and Hopelessness in Psychiatric Inpatients with Suicidal Ideation

INTRODUCTION

Suicide is a leading cause of death worldwide and models may help the understanding of the phenomenon and ultimately reduce its burden through effective suicide prevention strategies. The Interpersonal Theory of Suicide and Shneidman's Model have tried to describe different unmet needs related to suicidal ideation. The study aims to assess the association between thwarted belongingness, perceived burdensomeness, and suicidal ideation in a sample of psychiatric inpatients and the mediating role of hopelessness and mental pain in this association.

METHODS

112 consecutive adult psychiatric inpatients were administered the Columbia Suicide Severity Rating Scale (C-SSRS), the Italian version of the Interpersonal Needs Questionnaire-15-I (INQ-15-I), the Physical and Psychological Pain Scale, and the Beck Hopelessness Scale (BHS).

RESULTS

Mediation models indicated a significant indirect effect of perceived burdensomeness (with thwarted belongingness as covariates) on suicidal ideation intensity with hopelessness as a mediator. When thwarted belongingness (controlling for perceived burdensomeness as a covariate) was included in a model as an independent variable, direct and indirect effects on suicidal ideation intensity were not significant.

CONCLUSIONS

Psychosocial interventions focusing on identifying and decreasing the perception of being a burden for others and the feeling hopeless could represent a powerful pathway for reducing suicidal ideation. Moreover, the attention toward unmet interpersonal needs may help increase and focus clinical discussions on risk factors, which may help engagement toward psychiatric care and downsize the stigma related to suicide. Raising awareness toward mental health topics is a goal of healthcare services globally.

Self-burdensomeness, other-burdensomeness, and suicidal ideation

Perceiving oneself as a burden to others (other-burdensomeness), as well as perceiving one's selfhood as a burden (self-burdensomeness), have been proposed as risk factors for suicidal ideation. Yet, it is unclear whether the altruistic motive of being a burden to others or the self-oriented motive of being a burden on oneself is more relevant to suicidal ideation. Given this background, two rival mediation models were tested. Data from N = 228 outpatients (64% female; age: M(SD) = 38.69 (12.27), range:17-65) undergoing psychotherapy were collected at two measurement time points over a three-month period (first measurement = T1, second measurement = T2). The significant positive association between other-burdensomeness (T1) and suicidal ideation (T2) was partially mediated by self-burdensomeness (T1). Furthermore, the significant positive association between self-burdensomeness (T1) and suicidal ideation (T2) was partially mediated by other-burdensomeness (T1). Results suggest that suicidal ideation can develop from both an altruistic, self-sacrificial perception of being a burden to others, as well as from a more self-oriented perception of being a burden to oneself. There is no indication that either self-burdensomeness or other-burdensomeness is a stronger indicator in the development of suicidal ideation.

Does panic disorder increase the risk of cardiovascular diseases in diabetics?: A nationwide population-based study

BACKGROUND

Several studies have suggested a link between panic disorder (PD) and cardiovascular disease (CVD). However, the extent to which PD confers risk for CVD is still unclear, particularly in diabetics, a group showing high risk for CVD.

METHODS

A nationwide population-based cohort of 1,624,718 patients with type 2 diabetes were selected from the National Health Screening Program database covering the years 2009 to 2012. The subjects were divided into two groups: those without panic disorder (non-PD group, n = 1,618,263) and those with newly diagnosed PD (PD-group, n = 6455). Follow-up of subjects for up to 10 years was conducted for evaluation of the incidences of myocardial infarction (MI), stroke, and death.

RESULTS

After adjusting for the baseline covariates and diabetes mellitus (DM)-related variables, no difference in the future risk of MI and stroke was observed between the non-PD group and the PD group. Compared with the non-PD group, the PD group showed an increase in the future risk of death. [adjusted hazard ratio (aHR) = 1.120, 95 % confidence interval (CI): 1.039-1.206]. In contrast to the population aged <40 and > 65 years, in the age group of 40-64 years a significantly higher risk of stroke was observed in the PD group compared with the non-PD group (aHR = 1.352, 95%CI: 1.136-1.610).

LIMITATION

The diagnoses were based on the diagnostic codes of the claim data.

CONCLUSION

The current findings suggested that PD might not contribute to the risk of future MI and stroke in diabetics who have already been at risk of various cardiovascular complications.

Predicting suicidal ideation in a nationally representative sample of young adults: a 12-month prospective study

BACKGROUND

Evidence-based theoretical models outlining the pathways to the development of suicidal ideation may inform treatment. The current research draws from the Interpersonal Theory of Suicide (IPT) and the Integrated Motivational-Volitional (IMV) Model of suicidal behaviour and aims to test the interaction between perceived burdensomeness and thwarted belongingness as proposed by the IPT model, and the defeat-entrapment pathway as proposed by the IMV model, in the prediction of suicidal ideation at 12-month follow-up.

METHODS

The Scottish Wellbeing Study is a nationally representative prospective study of young people aged 18-34 years (n = 3508) from across Scotland, who completed a baseline interview and a 12-month follow-up (n = 2420). The core factors from both the IPT (perceived burdensomeness and thwarted belongingness) and the IMV model (defeat, internal and external entrapment) were measured alongside demographics, depressive symptoms and suicidal ideation at baseline. At 12-month follow-up, suicidal ideation was assessed again.

RESULTS

In multiple regression analysis perceived burdensomeness and internal entrapment, with baseline suicidal ideation, predicted 12-month suicidal ideation. No support for the interaction between perceived burdensomeness and thwarted belongingness in predicting 12-month suicidal ideation was found. However, there was evidence that internal, but not external, entrapment mediated the relationship between defeat and 12-month suicidal ideation, but no support was found for the moderation of burdensomeness and belongingness on the entrapment to suicidal ideation pathway.

CONCLUSIONS

The current findings highlight the importance of targeting perceived burdensomeness and internal entrapment to reduce the likelihood that suicidal ideation emerges in at risk individuals.

Predicting suicidal ideation in a longitudinal high-risk sample: Multilevel analyses and 12-month trajectories

BACKGROUND

The Interpersonal Theory of Suicide states that suicidal ideation (SI) results from perceived burdensomeness (PB) and thwarted belongingness (TB). Cross-sectional studies found associations with SI. This study examined the prospective prediction of SI.

METHODS

Three hundred and eight inpatients reporting severe SI or a recent suicide attempt were assessed four times within 12 months. The prediction of SI was examined using multilevel analyses, group comparisons, and logistic regression analyses.

RESULTS

Cross-sectionally, PB and TB were associated with SI. Prospectively, neither PB nor TB predicted SI. We found no autocorrelation of SI over time. Patients with persistent and fluctuating SI reported higher PB at T0. PB predicted the persistence of SI over 12 months.

CONCLUSION

Results emphasize cross-sectional associations between PB, TB, and SI. PB and TB could not predict the intensity of SI over time. SI did not predict itself over time. PB was associated with a persistent trajectory of SI over 12 months.

Interpersonal theory of suicide: prospective examination

BACKGROUND

The interpersonal theory of suicide (IPTS) is one of the most intensively researched contemporary theories on the development of suicidal ideation and behaviour. However, there is a lack of carefully conducted prospective studies.

AIMS

To evaluate the main predictions of the IPTS regarding the importance of perceived burdensomeness, thwarted belongingness and capability for suicide in predicting future suicide attempts in a prospective design.

METHOD

Psychiatric in-patients (n = 308; 53.6% (n = 165) female; mean age 36.82 years, s.d. = 14.30, range 18-81) admitted for severe suicidal ideation (n = 145, 47.1%) or a suicide attempt completed self-report measures of thwarted belongingness, perceived burdensomeness, capability for suicide, hopelessness, depression and suicidal ideation as well as interviews on suicide intent and suicide attempts and were followed up for 12 months. Logistic regression and receiver operating characteristics (ROC) analysis were conducted.

RESULTS

The interaction of perceived burdensomeness, thwarted belongingness and capability for suicide was not predictive of future suicide attempts, but perceived burdensomeness showed a significant main effect (z = 3.49, P < 0.01; OR = 2.34, 95% CI 1.59-3.58) and moderate performance in screening for future suicide attempts (area under the curve AUC = 0.729, P < 0.01).

CONCLUSIONS

The results challenge the theoretical validity of the IPTS and its clinical utility - at least within the methodological limitations of the current study. Yet, findings underscore the importance of perceived burdensomeness in understanding suicidal ideation and behaviour.

Effectiveness of Psychotherapy on Suicidal Risk: A Systematic Review of Observational Studies

Background: Suicidal behavior is a major public health concern worldwide, and the interest in the development of novel and more efficient treatment strategies and therapies to reduce suicidal risk is increasing. Some recent studies have summarized the results of randomized clinical trials (RCTs) assessing the efficacy of psychotherapeutic tools designed to treat patients at suicidal risk. However, observational studies, which reflect real-world effectiveness and may use original approaches, have not been reviewed. Method: The aim of this study is to systematically review the available scientific evidence issued from observational studies on the clinical effectiveness of psychotherapeutic tools designed to treat patients at suicide risk. We have thus performed a systematic search of PubMed and Web of Science databases. Results: Out of 1578 papers, 40 original observational studies fulfilled our selection criteria. The most used psychotherapeutic treatments were dialectical behavioral therapy (DBT, 27.5%) and cognitive behavioral therapy (CBT, 15.0%) in patients with a diagnosis of borderline personality disorder (32.5%) and depression (15.0%). Despite the between-study heterogeneity, interventions lead to a reduction in suicidal outcomes, i.e., suicidal ideation (55.0%) and suicide attempts (37.5%). The content and reporting quality varied considerably between the studies. Conclusion: DBT and CBT are the most widely used psychotherapeutic interventions and show promising results in existing observational studies. Some of the included studies provide innovative approaches. Group therapies and internet-based therapies, which are cost-effective methods, are promising treatments and would need further study.

The clinical application of suicide risk assessment: A theory-driven approach

The interpersonal theory of suicide posits that thwarted belongingness (TB) and perceived burdensomeness (PB) increase suicide ideation; however, studies have found mixed results regarding this hypothesis among psychiatric inpatients. This study aimed to (a) demonstrate how assessing TB and PB using the Interpersonal Needs Questionnaire (INQ) can provide clinically useful information and (b) investigate how statistical methodology may impact the clinical application of the INQ. Participants were 139 (Sample 1) and 104 (Sample 2) psychiatric inpatients. In both samples, ordinal logistic regression results indicated TB and PB, separately, were significant predictors of suicide ideation-related outcomes; however, when examined as simultaneous predictors, TB was no longer a significant predictor. The interaction between TB and PB was not significant for either sample. Despite this, TB and PB scores provided clinically relevant information about suicide ideation-related outcomes. For example, the highest scores on TB and PB indicated a 93% and 95% chance of having some level of distress due to suicide ideation (Sample 1), a 91% and 92% chance of having some level of desire for death, and a 79% and 84% chance of having some level of desire for suicide, respectively (Sample 2). This study also proposes clinical cutoff scores for the INQ (for TB and PB, respectively, cutoff scores were 22 and 17 for distress due to suicide ideation, 33 and 17 for desire for death, and 31 and 22 for desire for suicide). Although these results indicate that multicollinearity between TB and PB may create interpretational ambiguity for clinicians, TB and PB may each be useful separate predictors of suicide ideation-related outcomes in psychiatric inpatient settings and should be incorporated into suicide risk assessment.

KEY PRACTITIONER MESSAGE

The 15-item Interpersonal Needs Questionnaire (an assessment of thwarted belongingness and perceived burdensomeness) should be incorporated into suicide risk assessment. Among psychiatric inpatients, greater thwarted belongingness and perceived burdensomeness, as separate predictors, were associated with increased levels of distress due to suicide ideation, desire for death, and desire for suicide. The highest scores on thwarted belongingness and perceived burdensomeness indicated a 79% to 95% chance of experiencing an elevated level of distress due to suicide ideation, desire for death, or desire for suicide. Recommended clinical cutoff scores were provided. For example, thwarted belongingness cutoff score of 31 and perceived burdensomeness cutoff score of 22 maximized the sensitivity and specificity of the INQ to detect some level of desire for suicide.

Measuring attitudes towards suicide: Preliminary evaluation of an attitude towards suicide scale

OBJECTIVES

Our study aimed to validate a previously published scale assessing attitudes towards suicide. Factor structure, convergent and discriminant validity, and predictive validity were investigated.

METHOD

Adult German participants (N=503; mean age=24.74years; age range=18-67years) anonymously completed a set of questionnaires. An exploratory factor analysis was conducted, and incongruous items were deleted. Subsequently, scale properties of the reduced scale and its construct validity were analyzed. A confirmatory factor analysis was then conducted in an independent sample (N=266; mean age=28.77years; age range=18-88years) to further confirm the factor structure of the questionnaire.

RESULTS

Parallel analysis indicated a three-factor solution, which was also supported by confirmatory factor analysis: right to commit suicide, interpersonal gesture and resilience. The subscales demonstrated acceptable construct and discriminant validity. Cronbach's α for the subscales ranged from 0.67 to 0.83, explaining 49.70% of the total variance.

CONCLUSIONS

Positive attitudes towards suicide proved to be predictive of suicide risk status, providing preliminary evidence for the utility of the scale. Future studies aiming to reproduce the factor structure in a more heterogeneous sample are warranted.
