Implicit measures of suicide vulnerability: Investigating suicide-related information-processing biases and a deficit in behavioral impulse control in a high-risk sample and healthy controls.

OBJECTIVE: Relevant implicit markers of suicidal thoughts and behaviors (STBs) have only been studied in isolation with mixed evidence. This is the first study that investigated a suicide attentional bias, a death-identity bias and a deficit in behavioral impulsivity in a high-risk sample and healthy controls. METHOD: We administered the Death Implicit Association Test, the Modified Suicide Stroop Task, and a Go/No-Go Task to inpatient suicide ideators (n = 42), suicide attempters (n = 40), and community controls (n = 61). RESULTS: Suicide ideators and attempters showed a suicide attentional bias and a death-identity bias compared to healthy controls. Ideators and attempters did not differ in these implicit information-processing biases. Notably, only attempters were more behaviorally impulsive compared to controls; however, ideators and attempters did not significantly differ in behavioral impulsivity. Moreover, implicit scores were positively intercorrelated in the total sample. CONCLUSION: In line with the Cognitive Model of Suicide, ideators and attempters display suicide-related information processing biases, which can be considered as implicit cognitive markers of suicide vulnerability. Furthermore, attempters have elevated levels of behavioral impulsiveness. These results are highly relevant in the context of crisis intervention strategies and warrant further research.

Torn between living or dying-analyses of influencing factors on suicide ambivalence and its longitudinally impact on suicidal ideation and behavior in a high-risk sample.

INTRODUCTION: Findings on the role of suicide ambivalence, an individual's wish to live (WL), and wish to die (WD) in the development of suicidality have been heterogenous. The main goal of this study was to examine associations of these constructs within the past week with sociodemographic factors and to longitudinally investigate their predictive power for suicidal ideation (SI) and suicide attempts (SA). METHODS: N = 308 patients (54% female; M = 36.92 years, SD = 14.30), admitted to a psychiatric ward due to suicidality, were assessed for all constructs after admission, after six, nine, and 12 months. Data were analyzed with univariate fixed-effect models and lagged mixed-effect regression models. RESULTS: Decreased, WL increased post-baseline. Gender showed no significant link to ambivalence, WD, and WL. Ambivalence and WD correlated negatively with age and positively with depressiveness. More participants in a relationship showed a WL compared with single/divorced/widowed participants. More single participants or those in a relationship showed ambivalence than divorced/widowed participants. More single participants showed a WD than participants in a relationship/divorced/widowed. Longitudinally, ambivalence and WD predicted SI and SA. CONCLUSION: The findings underscore the importance of taking suicide ambivalence and WD into account in risk assessment and treatment.

[Utilization of Outpatient Psychotherapy and Outpatient Psychiatric Treatment by Men and Women after Inpatient Treatment due to Suicide Attempt or Acute Suicidal Crisis]. / Inanspruchnahme ambulanter Psychotherapie und ambulanter psychiatrischer Behandlung von Männern und Frauen nach stationärer Behandlung aufgrund eines Suizidversuchs oder akuter suizidaler Krise.

OBJECTIVE: The strongest predictor of suicide attempts is a previous suicide attempt. Individuals hospitalized for suicidal ideation and behavior face an increased risk of suicide following discharge. This study investigates the extent to which outpatient treatment services are utilized the first 6 months after discharge and whether men and women differ in this regard. METHOD: The study examines data of 124 individuals (with suicide attempts (lifetime), 59.7% female) on the use of outpatient treatment services in the 6 months after inpatient treatment. RESULTS: 37.9% (N=47) of individuals reported not having used any treatment services at all. Men were significantly less likely to make use of the services. CONCLUSION: Members of a group with an increased risk of suicide, to a large extent, fail to make use of outpatient treatment services. Discharge management should increasingly focus on (gender-specific) barriers and pave the way for treatment in outpatient.

Understanding suicidal ideation-a network analysis of the Interpersonal Needs Questionnaire.

INTRODUCTION: Identifying various interacting risk factors for suicidality is important to develop preventive measures. The Interpersonal-Psychological Theory of Suicidal Behavior (IPTS) postulates suicidal ideation resulting from the occurrence of Perceived Burdensomeness (PB) and Thwarted Belongingness (TB). Suicidal behavior ultimately occurs if people have a Capability for Suicide. In past studies, the validity of TB was often not empirically confirmed, questioning which of the aspects of TB are central and related to suicidal ideation and whether applied measurement methods adequately capture the construct. METHOD: Using a sample of 3,404 individuals from different clinical and nonclinical settings, 30% (1,023) of whom reported suicidal ideation, two network analyses were conducted on the Interpersonal Needs Questionnaire (INQ) and a variable mapping suicidal ideation. RESULTS: Analyses revealed that some items of the INQ were not related to suicidal ideation and the most central items did not have the strongest associations to suicidal ideation. CONCLUSION: Based on these results, a shortened version of the INQ with the four items that showed the strongest associations with suicidal ideation in the network analyses was suggested.

Attachment and need to belong as moderators of the relationship between thwarted belongingness and suicidal ideation.

BACKGROUND: In the Interpersonal Theory of Suicide, thwarted belongingness is presented as a main predictor for suicidal ideation. Studies only partially support this prediction. The aim of this study was to examine whether the heterogenous results are due to moderating effects of attachment and the need to belong on the association between thwarted belongingness and suicidal ideation. METHODS: Four hundred forty-five participants (75% female) from a community sample aged 18 to 73 (M = 29.90, SD = 11.64) filled out online questionnaires about romantic attachment, their need to belong, thwarted belongingness, and suicidal ideation cross-sectionally. Correlations and moderated regression analyses were conducted. RESULTS: The need to belong significantly moderated the relationship between thwarted belongingness and suicidal ideation and was associated with higher levels of anxious attachment and avoidant attachment. Both attachment dimensions were significant moderators of the relationship between thwarted belongingness and suicidal ideation. CONCLUSION: Anxious and avoidant attachment as well as a high need to belong are risk factors for suicidal ideation in people with thwarted belongingness. Therefore, attachment style and need to belong should both be considered in suicide risk assessment and therapy.

Trapped in my inner prison-Cross-sectional examination of internal and external entrapment, hopelessness and suicidal ideation.

BACKGROUND: Within the integrated motivational-volitional model of suicidal behavior, entrapment that consecutively leads to hopelessness is considered as a proximal risk factor for suicidal ideation. Entrapment can refer to both external and internal circumstances whereby results of recent studies indicate that internal entrapment plays a more important role than external entrapment in the development of suicidal ideation. It has been considered that to escape internal entrapment might be more complicated than to change external circumstances. However, it remains unclear whether the greater effect of internal entrapment on suicidal ideation is due to greater feelings of hopelessness. Therefore, the aim of this study was to address this research gap and to examine the effects of internal and external entrapment on hopelessness and suicidal ideation. METHODS: N = 454 participants from a community sample (75% female) aged between 18 and 73 years (M = 29.91, SD = 11.56) conducted a cross-sectional online survey. All participants were assessed for suicidal ideation, hopelessness, and internal as well as external entrapment. Pearson product-moment correlations and two mediation analyses were conducted. RESULTS: All constructs were significantly correlated. For both internal and external entrapment, an effect on suicidal ideation was found. Both effects were partially mediated by hopelessness, this mediation was larger for external entrapment. The completely standardized indirect effect used to compare the mediation models was larger for external entrapment than for internal entrapment. CONCLUSIONS: Hopelessness mediated the association between external entrapment as well as internal entrapment and suicidal ideation. This effect was larger for external entrapment.

The Mereology of Depression-Networks of Depressive Symptoms during the Course of Psychotherapy.

(1) Background: Research has shown that it is important to examine depressive symptoms in the light of the mereology (the ratio between one symptom and the whole disorder). The goal of this study was to examine changes in the symptom interrelations of patients undergoing cognitive behavioral therapy treatment (CBT) via network analyses. (2) Method: Outpatients with depressive symptoms (N = 401) were assessed with the Beck Depression Inventory three times (pretreatment, after 12 sessions, and post-treatment) during CBT. Gaussian graphical models were used to estimate the relationships among symptoms. (3) Results: The severity of depressive symptoms significantly decreased over the course of therapy, but connectivity in the networks significantly increased. Communities of symptoms changed during treatment. The most central and predictable symptom was worthlessness at baseline and after 12 sessions, and loss of energy and self-dislike at post-treatment. (4) Conclusion: The results indicate that the severity of depressive symptoms decreased during cognitive behavior therapy, while network connectivity increased. Furthermore, the associations among symptoms and their centrality changed during the course of therapy. Future studies may investigate individual differences and their impact on the planning of psychotherapeutic treatment.
