The prospective role of defeat and entrapment in depression and anxiety: a 12-month longitudinal study

Sex differences in entrapment in a multinational sample: a network analysis perspective

Background

The concept of entrapment has been highlighted as a transdiagnostic element that manifests itself in disorders such as depression, anxiety, and suicidal ideation. Although research has been conducted in different contexts independently, a comprehensive multi-country study to assess gender differences in entrapment through network analysis has not yet been carried out. The objective of this study was to evaluate the entrapment network in men and women at the multinational level.

Methods

A sample of 2,949 participants, ranging in age from 18 to 73 years from six countries (Germany, Iran, Spain, Slovakia, El Salvador, and Peru), was considered. They completed the entrapment scale. A network analysis was performed for both men and women to identify the connectivity between indicators and the formation of clusters and domains, in addition to the centrality assessment in both sex groups.

Results

The study findings revealed the presence of a third domain focused on external interpersonal entrapment in the network of men and women. However, in relation to the interconnectivity between domains, variations were evidenced in both networks, as well as in centrality, it was reported that men present a greater generalized entrapment in various aspects of life, while women tend to experience a more focused entrapment in expressions of intense emotional charge.

Conclusion

The multinational study identified variations in the structure of entrapment between genders, with three domains (internal, external, and external-interpersonal) and differences in the interaction of indicators and groupings, as well as discrepancies in centrality.

Threat, safety, safeness and social safeness 30 years on: Fundamental dimensions and distinctions for mental health and well-being

In 1993, the British Journal of Clinical Psychology published my paper titled 'Defence and safety: Their function in social behaviour and psychopathology'. The paper highlights that to understand people's sensitivity to threat, we also need to understand their ability to identify what is safe. This paper offers an update on these concepts, highlighting distinctions that were implicit but not clearly defined at the time. Hence, the paper seeks to clarify distinctions between: (i) threat detection and response, (ii) safety and safety seeking, (iii) safeness and (iv) their social and non-social functions and forms. Threat detection and response are to prevent or minimize harm (e.g., run from a predator or fire). Safety checking relates to monitoring for the absence and avoidance of threat, while safety seeking links to the destination of the defensive behaviour (e.g., running home). Safety seeking also relates to maintaining vigilance to the appearance of potential harms and doing things believed to avoid harm. Threat-defending and safety checking and seeking are regulated primarily through evolved threat processing systems that monitor the nature, presence, controllability and/or absence of threat (e.g., amygdala and sympathetic nervous system). Safeness uses different monitoring systems via different psychophysiological systems (e.g., prefrontal cortex, parasympathetic system) for the presence of internal and external resources that support threat-coping, risk-taking, resource exploration. Creating brain states that recruit safeness processing can impact how standard evidence-based therapies (e.g., exposure, distress tolerance and reappraisal) are experienced and produce long-term change.

Relationships of work stress and interpersonal needs with industrial workers' mental health: a moderated mediation model

OBJECTIVES

This study explores whether feelings of defeat (i.e., a sense of failed struggle and losing rank; referred to as defeat for simplicity) mediated the effect of work stress on depression/anxiety, the effect of interpersonal needs on depression/anxiety for Chinese industrial workers, and the possible moderating role of social support.

METHOD

A cross-sectional study was conducted in Shenzhen, China in 2019, in total, 2023 industrial workers (of 2700 invited; response rate = 75%) completed a self-administered survey consisted of Job Stress Scale, Interpersonal Needs Questionnaire, Defeat Scale, Centre for Epidemiological Studies Depression Scale, Generalized Anxiety Disorder Scale, two face-valid questions for social support, as well as sociodemographic information. Moderated mediation model was tested and loop plots were applied to probe into the conditional effects of work and interpersonal stress on depression and anxiety symptoms.

RESULT

Both the direct and indirect effect of work stress on depression and anxiety through defeat were significant (Work stress→ Depression: B = 0.035, p < .001, Work stress→ Defeat→ Depression: B = 0.034, p < .001; Work stress→ Anxiety: B = 0.038, p < .001, Work stress→ Defeat→ Anxiety: B = 0.045, p < .001). Meanwhile, defeat mediated the relationship of interpersonal needs with depression partially and the relationship of interpersonal needs with anxiety totally (Interpersonal needs→ Anxiety: B = 0.133, p < .001, Interpersonal needs→ Defeat→ Anxiety: B = 0.010, p = .537). Social support moderated the indirect path between interpersonal needs and depression/anxiety and buffered the effect.

CONCLUSION

The mediating role of defeat and the moderator role of social support in the relationship between stress and depression/anxiety were confirmed in industrial workers. Workers who reported more work and interpersonal stress would report more defeat feelings, and then exhibited more depression and anxiety symptoms; this mediation effect was stronger for those who had lower social support, respectively.

Predicting the risk of HIV infection among internal migrant MSM in China: An optimal model based on three variable selection methods

Introduction

Internal migrant Men who have sex with men (IMMSM), which has the dual identity of MSM and floating population, should be more concerned among the vulnerable groups for HIV in society. Establishing appropriate prediction models to assess the risk of HIV infection among IMMSM is of great significance to against HIV infection and transmission.

Methods

HIV and syphilis infection were detected using rapid test kits, and other 30 variables were collected among IMMSM through questionnaire. Taking HIV infection status as the dependent variable, three methods were used to screen predictors and three prediction models were developed respectively. The Hosmer-Lemeshow test was performed to verify the fit of the models, and the net classification improvement and integrated discrimination improvement were used to compare these models to determine the optimal model. Based on the optimal model, a prediction nomogram was developed as an instrument to assess the risk of HIV infection among IMMSM. To quantify the predictive ability of the nomogram, the C-index measurement was performed, and internal validation was performed using bootstrap method. The receiver operating characteristic (ROC) curve, calibration plot and dynamic component analysis (DCA) were respectively performed to assess the efficacy, accuracy and clinical utility of the prediction nomogram.

Results

In this study, 12.52% IMMSMs were tested HIV-positive and 8.0% IMMSMs were tested syphilis-positive. Model A, model B, and model C fitted well, and model B was the optimal model. A nomogram was developed based on the model B. The C-index of the nomogram was 0.757 (95% CI: 0.701-0.812), and the C-index of internal verification was 0.705.

Conclusions

The model established by stepwise selection methods incorporating 11 risk factors (age, education, marriage, monthly income, verbal violence, syphilis, score of CUSS, score of RSES, score of ULS, score of ES and score of DS) was the optimal model that achieved the best predictive power. The risk nomogram based on the optimal model had relatively good efficacy, accuracy and clinical utility in identifying internal migrant MSM at high-risk for HIV infection, which is helpful for developing targeted intervention for them.

Examining the protective influence of posttraumatic growth on interpersonal suicide risk factors in a 6-week longitudinal study

Research has found an inverse relationship between posttraumatic growth (PTG) and suicidal ideation in military and community samples that holds when controlling for other suicide risk factors. However, further research is needed into the underlying mechanisms to clarify how PTG protects against the formation of suicidal ideation. The current two-wave longitudinal study examined whether perceiving PTG from recent adverse circumstances while in a national lockdown during the COVID-19 pandemic attenuated the positive relationship of two interpersonal suicide risk factors – perceived burdensomeness (PB) and thwarted belonginess (TB)–over 6 weeks. Participants (n = 170) were recruited online from Prolific from income-deprived areas in the United Kingdom (mean age = 37.65; SD = 12.50; 53.5% female). Post-hoc power analyses indicated we had insufficient power to examine the hypothesised mediation for TB. We examined whether PTG mediated the relationship between PB at wave 1 and wave 2 while controlling for depression and anxiety in a sample of individuals at-risk for suicidal ideation. PTG did significantly and partially mediate the positive relationship between PB at wave 1 and 2. We discuss the theoretical and clinical implications that could result if future research successfully replicates these initial exploratory findings.

Defeat, Entrapment, and Hopelessness: Clarifying Interrelationships between Suicidogenic Constructs

Psychological theories of suicide posit conceptually similar constructs related to the development of suicidal thinking. These constructs often evince high-magnitude interrelationships across studies. Within these theories, defeat, entrapment and hopelessness standout as conceptually and quantitatively similar. Theoretical improvements may be facilitated through clarifying the subscale and item-level similarities among these constructs. Factor analytic and phenomenological work has demonstrated equivocal evidence for a distinction between defeat and entrapment; hopelessness is not typically analyzed together with defeat and entrapment despite evidence of large-magnitude interrelationships. This study explored the interrelationships among the foregoing constructs within a sample of undergraduate students (N = 344) from two universities within the Southeastern United States. Participants, oversampled for lifetime history of suicidal ideation and attempts, completed an online cross-sectional survey assessing defeat, entrapment, hopelessness and SI. Exploratory factor and parallel analyses demonstrated support for a one factor solution when analyzed at subscale level of the three measures as well as when all items of the three measures were analyzed together. Ad hoc exploratory structural equation modeling (ESEM) bifactor results evinced support for the existence of a single, general factor at the item level. Item level communalities and bifactor fit indices suggest that hopelessness may be somewhat distinct from defeat and entrapment. Clinical and theoretical implications are discussed in the context of study limitations.

Defeat and Entrapment Mediate the Relationship Between Insomnia Symptoms and Suicidal Ideation in Young Adults

AIM

In recent years, there has been a growing interest in understanding the relationship between sleep disturbance and suicide. The current study aimed to advance understanding of the psychological processes driving these relationships by examining whether insomnia symptoms are related to suicidal ideation via perceptions of defeat and entrapment.

METHODS

Young adults (n = 259; 202 students [78.0%], 45 employed [17.4%], 12 unemployed [4.6%]) completed an anonymous self-report survey that was advertised via social media, university participant pools, and fliers. The survey was described as being related to sleep and mood/mental health. Validated measures were used to assess insomnia symptoms, chronotype, defeat, entrapment, suicidal ideation, and affective covariates.

RESULTS

Bivariate associations found insomnia severity to be related to poorer affective outcomes including severity of suicidal ideation. Insomnia and depression were significant independent variables in multiple linear regression with suidical ideation as the dependent variable. The relationship between insomnia and suicidal ideation was mediated by perceptions of defeat and entrapment.

CONCLUSION

Taken together, these findings shed light on the psychological mechanisms linking sleep disturbance and suicidal ideation by highlighting the role of defeat and entrapment. These findings have the potential to improve suicide risk assessment and prevention in young adults experiencing difficulties initiating or maintaining sleep.HighlightsDefeat and entrapment mediate relationship between insomnia and suicidal ideationEvidence for Integrated Motivational-Volitional Model of Suicidal Behavior in community sampleUses validated multi-item suicide measure.

Desire for control and the integrated motivational-volitional model of suicidal behavior: Results from a pilot investigation of adults in the United Kingdom

BACKGROUND

Suicidal behavior remains a pressing problem in the United Kingdom. Continued theory development is a critical step toward designing effective prevention.

AIMS

The present study tested a novel element to suicide theory, the Desire for Control, for its direct and moderating roles within the Integrated Motivational-Volitional (IMV) Model of Suicidal Behavior.

METHOD

An online-administered cross-sectional suicide risk survey study (n = 116) was conducted among adults living in the United Kingdom.

RESULTS

Mean suicidal ideation scores were in the non-clinical range. DOC Leadership and Destiny Control were associated with good mental health. DOC Decision Avoidance was associated with poor mental health. DOC Decision Avoidance also acted as a motivational moderator in which the entrapment-suicidal thinking link was worse among those high in decisional avoidance.

CONCLUSION

DOC represents a novel, valuable addition to suicide theory and may inform suicide-specific psychotherapeutic intervention. Additional research is needed to full understand the role of DOC and its factor structures in the IMV.

Examining the protective function of perceptions of post-traumatic growth against entrapment and suicidal ideation

BACKGROUND

Recent evidence has found that reporting post-traumatic growth (PTG) from a past stressful life event is associated with lower reports of suicidal ideation. Perceptions of PTG measure the extent to which an individual reports positive changes in their identity, relationships, and worldviews after a stressful event. However, little is known about how perceptions of PTG interact with feelings of defeat and entrapment to influence suicidal ideation. The current study examined this question through the Integrated Motivational-Volitional (IMV) Model of Suicidal Behavior.

METHODS

521 adult participants (315 females with age range of 18-82, M = 30.4 years, SD = 13.6) completed an online cross-sectional questionnaire with defeat, entrapment, suicidal ideation, PTG, depression and anxiety measures. Hypotheses and data analysis plans were pre-registered prior to data collection.

RESULTS

PTG negatively correlated with defeat, entrapment and suicidal ideation. PTG predicted lower suicidal ideation when controlling for entrapment, depression and anxiety. PTG did not moderate the relationship between defeat on entrapment or the relationship between entrapment on suicidal ideation.

LIMITATIONS

The findings were based on cross-sectional data where participants recalled experiences of defeat, entrapment and suicidal ideation from the past year. The sample was a large community (non-clinical) sample, and most of the participants identified as white (85%).

CONCLUSION

Although PTG did not function as a moderator within the IMV model of suicidality, it predicted lower suicidal ideation while controlling for other known predictors of suicidal ideation. Future research could explore the function of PTG in appraisal-based models of suicidality.

The association between entrapment and depression among migrant workers in China: a social rank theory based study

BACKGROUND

Migrant workers are a group susceptible for depression evolution due to occupational maladaptive triggers. The social rank theory illustrates the pathology process from defensive adaptation to depression, pointing out the early prevention of depression by discovering entrapment. This study aims to reveal the relationship between migrant workers' entrapment and depressive symptoms.

METHODS

A total of 1805 migrant workers in Shenzhen were recruited by stratified multi-stage sampling. Sample's demographic, behavioral and psychosocial characteristics were described and analyzed to reveal the relationship between entrapment and depressive symptoms. The Receiver Operator Characteristic was performed to find the optimal cut-off point of Entrapment Scale for predicting depressive symptoms.

RESULTS

In the binary logistic regression of sociodemographic variables, migrant workers who were married (univariate odds ratio (ORu) = 0.69, 95% Confidence Interval (CI) = 0.56-0.84), owned 1 or 2 children (ORu = 0.71, 95% CI = 0.58-0.86), had been working over 10 years (ORu = 0.71, 95% CI = 0.54-0.95), earned > 4999 yuan per month (ORu = 0.68, 95% CI = 0.47-0.99; multivariate odds ratio (ORm) = 0.57, 95% CI = 0.38-0.87) or with low risks of alcohol use disorders (ORu = 0.51, 95% CI = 0.34-0.75) had lower risks of depressive symptoms. After adjusted the aforementioned significant sociodemographic variables, migrant workers with severer entrapment were more likely to have depressive symptoms (adjusted odds ratio (ORa) = 1.13, 95% CI = 1.12-1.15). Besides, the study proved the reliability and validity of the Chinese version Entrapment Scale, preferring a two-dimensional structure, and 11 was the optimal cut-off value of this scale for predicting depressive symptoms among migrant workers.

CONCLUSIONS

This result indicates the potential value of entrapment according to the social rank theory on facilitating early prevention of migrant works' depression and the application value of Entrapment Scale for effectively measuring mental status among migrant workers.

Human threat circuits: Threats of pain, aggressive conspecific, and predator elicit distinct BOLD activations in the amygdala and hypothalamus

INTRODUCTION

Threat processing, enabled by threat circuits, is supported by a remarkably conserved neural architecture across mammals. Threatening stimuli relevant for most species include the threat of being attacked by a predator or an aggressive conspecific and the threat of pain. Extensive studies in rodents have associated the threats of pain, predator attack and aggressive conspecific attack with distinct neural circuits in subregions of the amygdala, the hypothalamus and the periaqueductal gray. Bearing in mind the considerable conservation of both the anatomy of these regions and defensive behaviors across mammalian species, we hypothesized that distinct brain activity corresponding to the threats of pain, predator attack and aggressive conspecific attack would also exist in human subcortical brain regions.

METHODS

Forty healthy female subjects underwent fMRI scanning during aversive classical conditioning. In close analogy to rodent studies, threat stimuli consisted of painful electric shocks, a short video clip of an attacking bear and a short video clip of an attacking man. Threat processing was conceptualized as the expectation of the aversive stimulus during the presentation of the conditioned stimulus.

RESULTS

Our results demonstrate differential brain activations in the left and right amygdala as well as in the left hypothalamus for the threats of pain, predator attack and aggressive conspecific attack, for the first time showing distinct threat-related brain activity within the human subcortical brain. Specifically, the threat of pain showed an increase of activity in the left and right amygdala and the left hypothalamus compared to the threat of conspecific attack (pain > conspecific), and increased activity in the left amygdala compared to the threat of predator attack (pain > predator). Threat of conspecific attack revealed heightened activity in the right amygdala, both in comparison to threat of pain (conspecific > pain) and threat of predator attack (conspecific > predator). Finally, for the condition threat of predator attack we found increased activity in the bilateral amygdala and the hypothalamus when compared to threat of conspecific attack (predator > conspecific). No significant clusters were found for the contrast predator attack > pain.

CONCLUSION

Results suggest that threat type-specific circuits identified in rodents might be conserved in the human brain.

A Latent Profile Analysis of Psychotic Experiences, Non-psychotic Symptoms, Suicidal Ideation and Underlying Mechanisms in a Sample of Adolescents From the General Population

Psychotic experiences (PEs) are prevalent in the general population, particularly in adolescents. PEs are associated with various negative outcomes such as psychotic, depressive, anxiety and post-traumatic stress disorders and suicidal behavior. Recent studies in the general population have suggested that what makes PEs relevant is not so much the experiences per se, but their association with non-psychotic comorbidity and other transdiagnostic domains. Thus, there is a need for a better understanding of how PEs exist in a larger psychopathological context in adolescents. In the present study we aimed to explore this, using latent profile analysis (LPA) to identify different patterns in which PEs, psychiatric symptoms and psychological processes co-occur. LPA was conducted using data from an adolescent general population subsample (n = 335) with PEs. We conducted LPA, using measures of PEs, psychiatric symptoms and behaviors (depression, anxiety post-traumatic stress disorder and suicidal behavior) and cognitive and affective processes of entrapment/defeat and emotional regulation as manifest variables. We found that the best fit was obtained with a four-class solution that distinguished primarily between different levels of overall severity: "low symptomatology" (19.1%), "mild-moderate symptomatology" (39.4%), "moderate symptomatology" (33.7%); "high symptomatology" (7.8%). Levels of depression, post-traumatic stress symptoms and defeat/entrapment were most differentiated between classes. The high symptomatology group showed the highest scores in all psychiatric symptoms suicidal ideation, and emotional/cognitive domains, except in cognitive reappraisal. This group also showed the highest usage of emotional suppression. Our results suggest that the assessment of mental health risk in adolescents should be aware that PEs exist in a broad context of other domains of psychopathology and transdiagnostic cognitive and affective processes.

Psychometric properties of the Suicidal Ideation Attributes Scale (SIDAS) in a longitudinal sample of people experiencing non-affective psychosis

BACKGROUND

Suicidal ideation is a key precursor for suicide attempts and suicide deaths. Performing routine screening of suicide precursors can help identify people who are at high risk of death by suicide. This is, arguably, an important suicide prevention effort. The aim of this study was to assess the validity, reliability, and factor structure of the Suicidal Ideation Attributes Scale (SIDAS) in a three-month longitudinal study with people with a diagnosis of schizophrenia or non-affective psychosis and experiences of suicidal ideation and/or behaviours. It was predicted that the SIDAS would have high internal consistency, test-retest reliability, convergent, discriminant and construct validity.

METHODS

Ninety-nine participants experiencing psychosis completed the SIDAS at baseline and 89 participants completed it 3 months later. Additionally, participants completed a demographic questionnaire, the Beck Scale for Suicide Ideation, the Beck Hopelessness Scale, and the Defeat and Entrapment Scales. The internal consistency, test-retest reliability, convergent validity, and discriminant validity of the SIDAS were investigated in comparison to other constructs. Factor analysis was performed to examine the factor structure of the scale.

RESULTS

Principal component analysis yielded a theoretically coherent one-dimensional factor structure of SIDAS, suggesting good construct validity (PCA = .71). The SIDAS had high internal consistency (α = .89) and good test-retest reliability (α = .73). It was highly correlated with other self-report measures, including the Beck Scale for Suicide Ideation, Beck Hopelessness Scale, Defeat and Entrapment scales, indicating excellent construct validity.

CONCLUSION

The SIDAS is a valid and reliable self-report instrument for assessing the severity of suicidal ideation in a population of people with a diagnosis of schizophrenia or non-affective psychosis. Further research should test the psychometric properties of the scale in individuals experiencing different mental health problems in cross-cultural settings, in order to establish its broader validity, reliability, and clinical utility.

The Mental Health and Syndemic Effect on Suicidal Ideation among Migrant Workers in China: A Cross-Sectional Study

Background: Migrant workers are in a socially disadvantaged position and thus suffer from more stress and mental health disorders, resulting in a high risk of suicidal ideation. This study aimed to explore the association between psychosocial problems and suicidal ideation, and the syndemic effect of concurrent psychosocial problems on suicidal ideation among migrant workers. Methods: We conducted a cross-sectional study and recruited 1805 migrant workers in Shenzhen, China. Each participant completed a self-administered questionnaire to report sociodemographic information and mental health status. Univariate and multivariate logistic regression were used to explore the association between psychosocial variables and suicidal ideation, and their syndemic effect on suicidal ideation. Results: The prevalence of suicidal ideation among migrant workers was 7.5%. All selected psychosocial variables were independently associated with suicidal ideation. Multivariate logistic regression analysis showed that three psychosocial variables were associated with suicidal ideation: anxiety (ORm: 1783, 95% CI: 1.089–2.920), entrapment (ORm: 2.064, 95% CI: 1.257–3.388), and defeat (ORm: 2.572, 95% CI: 1.612–4.103). Various mental health issues can exist simultaneously to increase the risk of suicidal ideation (AOR: 5.762, 95% CI: 3.773–8.802). Workers with more psychosocial problems were more likely to have suicidal ideation. Conclusions: The association between poor mental health and suicidal ideation should not be overlooked among migrant workers. The co-occurring or syndemic effect of psychosocial problems may increase the risk of suicidal ideation.

Followers' unclear demands during the COVID-19 pandemic can undermine leaders' well-being: A moderated mediation model from an entrapment perspective

Although effective leaders are important for reducing employee stress during the COVID-19, limited studies have examined how follower behaviors can influence leader stress and well-being during the COVID-19. This study draws on defeat-entrapment theory to examine how followers' unclear demands during the COVID-19 consequently impact leaders' psychological states and well-being. We conducted a three-wave time-lagged investigation with a sample of 281 leaders in the United Kingdom and found that followers' unclear demands could generate feelings of entrapment in leaders, leading to decreased levels of well-being outcomes in leaders. Importantly, we found that leaders who have higher levels of leadership responsibility during the COVID-19 are likely to feel trapped by followers' unclear demands. They are also likely to face higher levels of feelings of entrapment and impaired well-being compared with leaders who have lower levels of leadership responsibility. We discuss the implications for theories and practices, as well as directions for future research.

The syndemic condition of psychosocial problems related to depression among sexually transmitted infections patients

BACKGROUND

The prevalence of depression in sexually transmitted infections (STIs) patients is much higher than general public. However, studies focusing on comprehensive psychosocial effects on depression among STIs patients are limited. This study aimed to examine association of multiple psychosocial syndemic conditions with depression among STIs patients in Shanghai, China.

METHODS

We conducted a cross-sectional study and recruited 910 STIs patients from Shanghai Skin Disease Hospital. Participants self-reported their demographics and themselves completed the scales of depression, self-esteem, loneliness, social support, entrapment, defeat and interpersonal needs. Logistic regressions were performed to detect the possible contributing psychosocial factors for depression and to verify the syndemic conditions of psychosocial problems.

RESULTS

Of the STIs patient sample, the prevalence of depression was 17.9%. Multivariable analysis showed low-level self-esteem (odds ratio [ORm]: 2.18, 95% CI [1.19-4.00]) and social support (ORm: 2.18, 95% CI [1.37-3.46]), high-level entrapment (ORm: 6.31, 95% CI [3.75-10.62]) and defeat (ORm: 2.60, 95% CI [1.51-4.48]) increased the risk of depression. Psychosocial syndemic conditions magnified effect in fusing depression (adjusted odds ratio [AOR]: 11.94, 95% CI [7.70-18.53]). Participants with more than 4 psychosocial problems were about 22 times more likely to have depression (AOR: 22.12, 95% CI [13.19-37.09]).

CONCLUSIONS

The psychosocial problems syndemic magnifying the risk of depression was confirmed and psychosocial interventions to prevent depression is needed among STIs patients.

Being Trapped and Seeing No Way Out - Effects of Entrapment on Treatment Outcome in an Interdisciplinary Pain Treatment

BACKGROUND

Entrapment describes a feeling of being stuck in an inescapable aversive situation. This feeling often arises in the context of uncontrollable and/or chronic stress and is associated with various psychopathologies.

OBJECTIVE

Owing to the nature of their disease, also chronic pain, patients might experience their situation as unremitting and inescapable. The aim of the present study was to examine the role of entrapment in patients with a chronic pain disorder and the association of entrapment with treatment outcome.

METHODS

A total of 189 patients with a chronic pain disorder where psychological factors play a decisive role in its severity, exacerbation, and maintenance (International Classification of Diseases, ICD-10: F45.41, "Chronic pain disorder with somatic and psychologic factors") receiving inpatient care completed a set of standardized self-report questionnaires at intake and discharge of an interdisciplinary pain treatment. To analyze the effects of entrapment on pain-related interference and psychologic distress, hierarchical linear models were used.

RESULTS

Over treatment, reduced levels of entrapment were observed, which were associated with decreases in psychologic distress and pain-related interference at discharge.

CONCLUSION

Results support the relevance of entrapment in chronic pain and its treatment. To further improve interdisciplinary pain treatments, entrapment should be assessed and targeted by according interventions.

Evaluating the validity and reliability of the Chinese entrapment scale and the relationship to depression among men who have sex with men in Shanghai, China

BACKGROUND

Perception of entrapment can emerge when someone feels trapped in an aversive situation and incapable of escape. Depression is closely related to the construct of entrapment. In China, men who have sex with men (MSM) have a high prevalence of depression; therefore, a tool to evaluate entrapment in this population is needed. We evaluated the validity and reliability of the Chinese version of the entrapment scale (ES) and the relationship to depression among MSM in Shanghai, China.

METHODS

We recruited 304 MSM from four districts in Shanghai, China. Participants completed health behavior questionnaires that included baseline information and psychological measurements such as the ES and Patient Health Questionnaire (PHQ-9). The sample was randomly divided into two groups for exploratory factor analysis (n = 143) and confirmatory factor analysis (n = 161). Criterion validity was tested to explore the correlation between the ES and PHQ-9 scores. The reliability of the ES was evaluated with internal consistency reliability (Cronbach's α coefficient) and split-half reliability (Spearman-Brown coefficient). We performed hierarchical regression analysis to determine the variance explained of entrapment to predicting depressive symptoms after adjusting for sociodemographic factors. Finally, receiver operator characteristic curve analysis was performed to measure the optimal ES cut-off value for predicting depression.

RESULTS

Factor analysis showed the ES had one principal component, and one-dimensional scale had more acceptable model fit indices than two-dimensional model. The correlation coefficient between the ES and PHQ-9 scores was 0.756 (P < 0.01). The Cronbach's α coefficient was 0.970 and the Spearman-Brown coefficient was 0.976. ES scores significantly predicted an additional 45.1% of depressive symptoms after controlling for sociodemographic characteristics in the MSM population (β = 0.689, P < 0.001). The optimum cut-off value was 23, which had a sensitivity of 70% and a specificity of 85.4%.

CONCLUSIONS

The Chinese version of the ES has good validity and reliability in the MSM population in Shanghai, and can be used to evaluate perception of entrapment among MSM. The findings confirmed an association between entrapment and depression.

The Double Mediating Effect of Social Isolation and Emotional Support on Feelings of Entrapment and Motivation for Recovery among Korean Alcoholic Inpatients

This study identified the relationship between feeling of entrapment and motivation for change among hospitalized alcoholic patients and examined the double mediating effect model of social isolation and emotional support on this relationship. The study participants were 101 male and female alcoholic patients hospitalized at C hospital, which specializes in alcohol treatment at I city in Korea. PROCESS Macro 3.5 Model 6 was used for analyses of double mediating effects. The results revealed that entrapment and social isolation were negatively correlated with motivation for recovery of alcoholic inpatients, whereas emotional support was positively correlated with it. In a sequential double mediation model for motivation to change in alcoholic inpatients, the direct effects of social isolation and entrapment were not significant. However, the sequential indirect effect of social isolation and emotional support on entrapment and motivation for recovery among alcoholic inpatients was significant. These results suggest that making alcoholic inpatients not feel socially isolated by providing them with emotional support or through other means of assistance by practitioners or family members is important for their recovery from alcohol use disorder.

Stressed, depressed, and rank obsessed: Individual differences in compassion and neuroticism predispose towards rank-based depressive symptomatology

OBJECTIVES

As social creatures, we monitor our relative rank and/or status with others via social comparisons. Whilst research has identified perceptions of inferiority or 'low rank' relative to others is a robust predictor of depressive, anxious, and stress symptomology, to date individual differences have been ignored. We wish to provide empirical evidence to outline how differences across personality traits may interact with social rank variables to buffer or predispose towards depressive symptomology.

METHODS

Across three independent samples (N = 595), we replicated a social rank model of mental health, and with our third sample (N = 200), we sought to investigate attenuating roles for neuroticism versus compassion with multiple moderated regression models.

RESULTS

Neuroticism predicted greater levels of rank-associated depression, and compassion failed to function as a protective factor for rank-associated depression. However, a closer inspection of the original Big-5 factor structure positions this scale as a measure of 'interpersonal submissiveness' or 'conflict appeasement' rather than genuine compassion.

CONCLUSIONS

Whilst it is necessary to delineate the conditions where compassion is appropriate and able to lead to positive mental health outcomes, we argue this cannot be addressed with the Big-5 measure of trait compassion. We call for future work to consider valid and reliable measures for compassion, such as the self-compassion scale, submissive compassion scale, and fears of compassion scale, to more fully address how compassion may protect against both rank-based comparisons and severity of depression.

PRACTITIONER POINTS

Social rank mechanisms are robustly implicated in depression, anxiety, and stress. Clients who present as higher in neuroticism, inferiority, or submissiveness may be more prone towards rank-associated depression symptoms. Preliminary evidence suggests cultivation of genuine compassion can shift clients from a rank-focussed to a compassionate-focussed mentality, which aids mental health and fosters well-being.

Are negative beliefs about psychosis associated with emotional distress in adults and young people with such experiences? A meta-analysis

OBJECTIVE

Emotional distress, including depression and anxiety, is commonly reported amongst individuals experiencing psychosis. The beliefs individuals hold about the meaning of their psychosis may explain the distress they experience. The current meta-analysis aimed to review the association between beliefs about psychosis experiences and emotional distress.

METHOD

Three electronic databases (PsycINFO, MEDLINE, and CINAHL) were searched using keywords and controlled vocabulary (e.g., Medical Subject Headings) from date of inception to August 2019. A total of 19 eligible papers were identified.

RESULTS

Our random-effects meta-analysis revealed that depression and anxiety held moderate association with psychosis beliefs, with perceptions concerning a lack of control over experiences having the strongest association with distress. Longitudinal studies suggest that negative beliefs at baseline are associated with depressive symptoms at follow-up.

CONCLUSIONS

The results suggest that the endorsement of negative beliefs about psychosis is associated with current level of depression and anxiety. The results are consistent with theories of emotional distress in psychosis. However, the small number of longitudinal papers limits what can be concluded about the direction or other temporal characteristics of these relationships. Therapies that target unhelpful beliefs about psychosis may beneficial.

PRACTITIONER POINTS

Negative beliefs about experiences of psychosis are associated with greater emotional distress such as depression and anxiety. Beliefs about a lack of control over experiences had the strongest association with distress. Interventions that aim to modify or prevent the formation of unhelpful beliefs about psychosis may be beneficial for this population.

Defeat, Entrapment, and Positive Future Thinking: Examining Key Theoretical Predictors of Suicidal Ideation Among Adolescents

Adult-based suicide theories have determined much of what we know about suicidal ideation. Here, we investigate the extent to which elements of the Integrated Motivational-Volitional (IMV) model generalize to adolescence, a period when rates of suicidal ideation increase dramatically. In a sample of community-based adolescents (n = 74), we tested whether defeat and entrapment related to suicidal ideation, and whether poor positive future thinking abilities exacerbated this association. Consistent with the IMV model, we found that defeat/entrapment was associated specifically with history of suicidal ideation, and not with history of suicide attempt. Defeat/entrapment was related to baseline suicidal ideation severity above and beyond depressive symptoms. While defeat/entrapment predicted future suicidal ideation controlling for history of ideation, it did not do so controlling for depressive symptoms. Counter to the IMV model, we initially found that the association between defeat/entrapment and suicidal ideation was strongest among adolescents with greater positive future thinking abilities. This was driven by the tendency to imagine more positive future events, particularly those that are less realistic and achievable. These findings call for a more nuanced understanding of defeat/entrapment and positive future thinking among adolescents, particularly in how they interact to predict recurrent suicidal ideation.

Predictors of poor 6-week outcome in a cohort of major depressive disorder patients treated with antidepressant medication: the role of entrapment

BACKGROUND

Only a small number of consistent processes predict which depressed patients will achieve remission with antidepressant medication. One set of processes is that of social ranking strategies/variables that are related to life events and severe difficulties. Particularly, defeat and entrapment predict poorer response to antidepressants. However, results are inconsistent.

AIM

The current study aimed to evaluate evolutionary strategies, childhood maltreatment, neglect and life events and difficulties (LEDs) as predictors of remission in depressed patients undergoing pharmacological treatment in a psychiatric outpatient sample.

METHODS

A cohort of 139 depressed outpatients undergoing pharmacological treatment was followed prospectively in a naturalistic study for 6 weeks. Two major evaluations were considered at baseline and 6 weeks. We allocated patients to a pharmacological treatment algorithm for depression - the Texas Medication Algorithm Project. Variables evaluated at baseline and tested as predictors of remission included demographic and clinical data, severity of depression, social ranking, evolution informed variables, LEDs and childhood maltreatment.

RESULTS

Of the 139 patients, only 24.5% were remitted at week 6. In univariate analyses, non-remitted patients scored significantly higher in all psychopathology and vulnerability scales except for submissive behaviour and internal entrapment. For the logistic regression, a higher load of LEDs of the entrapment and humiliation dimension in the year before the index episode (OR = 6.62), and higher levels external entrapment in the Entrapment Scale (OR = 1.10) predicted non-remission. These variables accounted for 28.7% of the variance.

CONCLUSIONS

Multivariate analysis revealed that external entrapment was the only predictor of non-remission.

Does Mental Well-Being Protect against Self-Harm Thoughts and Behaviors during Adolescence? A Six-Month Prospective Investigation

Mental well-being protects against the emergence of suicidal thoughts. However, it is not clear whether these findings extend to self-harm thoughts and behaviors irrespective of intent during adolescence-or why this relationship exists. The current study aimed to test predictions-informed by the integrated motivational-volitional (IMV) model of suicide-concerning the role of perceived defeat and entrapment within the link between mental well-being and self-harm risk. Young people (n = 573) from secondary schools across Scotland completed an anonymous self-report survey at two time points, six months apart, that assessed mental well-being, self-harm thoughts and behaviors, depressive symptomology and feelings of defeat and entrapment. Mental well-being was associated with reduced defeat and entrapment (internal and external) and a decrease in the likelihood that a young person would engage in self-harm thoughts and behaviors. The relationship between mental well-being and thoughts of self-harm was mediated by perceptions of defeat and entrapment (internal and external). Mental well-being was indirectly related to self-harm behaviors via decreased feelings of defeat and internal (but not external) entrapment. Taken together, these findings provide novel insights into the psychological processes linking mental well-being and self-harm risk and highlight the importance of incorporating the promotion of mental well-being within future prevention and early intervention efforts.

Study protocol for a mixed methods prospective cohort study to explore experiences of care following a suicidal crisis in the Australian healthcare system

INTRODUCTION

For individuals presenting to the emergency department (ED) for a suicide attempt, the period after discharge from hospital is marked by heightened vulnerability for further suicide attempts. Effective care following a suicidal crisis has the potential to significantly decrease this risk. The current study aims to examine the impact of the LifeSpan multilevel suicide prevention model on experiences of care following a suicidal crisis. Perspectives from healthcare consumers (individuals who have presented to the ED following a suicidal crisis), carers, and health professionals will be explored. The LifeSpan model is currently being evaluated as a high-fidelity trial in four geographically defined regions in New South Wales, Australia.

METHODS AND ANALYSIS

This study will use a mixed methods prospective cohort design. Quantitative data collection includes a structured survey, administered to healthcare consumers from LifeSpan sites and control sites. Two cohorts of healthcare consumers will be recruited 12 months apart with baseline assessment occurring within 18 months of the ED presentation, and follow-up 12 months after the initial assessment. Survey participants will be recruited online and through participating EDs, mental health organisations and aftercare services. Qualitative interview data from healthcare consumers, carers who have accompanied a loved one to the ED following a suicidal crisis and health professionals who provide care to people at risk of suicide will be collected concurrently with the recruitment of the first cohort of survey participants. Purposive and convenience sampling techniques will be used for recruitment of interview participants. The primary outcome for this study will be healthcare consumers' experiences of service provided at the ED. Analysis will be undertaken of the change over time within LifeSpan sites, as well as between LifeSpan sites and control sites, using mixed effects repeated measures models as principal means of data analysis.

ETHICS AND DISSEMINATION

This research has been approved by the Hunter New England Human Research Ethics Committee (HREC/17/HNE/144). Results will be disseminated via conferences and peer-reviewed journals.

Do Feelings of Defeat and Entrapment Change over Time? An Investigation of the Integrated Motivational-Volitional Model of Suicidal Behaviour Using Ecological Momentary Assessments

(1) Background. Defeat and entrapment have been highlighted as major risk factors of suicidal ideation and behavior. Nevertheless, little is known about their short-term variability and their longitudinal association in real-time. Therefore, this study aims to investigate whether defeat and entrapment change over time and whether defeat predicts entrapment as stated by the integrated motivational-volitional model of suicidal behavior. (2) Methods. Healthy participants (n = 61) underwent a 7-day smartphone-based ecological momentary assessment (EMA) on suicidal ideation/behavior and relevant risk factors, including defeat and entrapment and a comprehensive baseline (T0) and post (T2) assessment. (3) Results. Mean squared successive differences (MSSD) and intraclass correlations (ICC) support the temporal instability as well as within-person variability of defeat and entrapment. Multilevel analyses revealed that during EMA, defeat was positively associated with entrapment at the same measurement. However, defeat could not predict entrapment to the next measurement (approximately two hours later). (4) Conclusion. This study provides evidence on the short-term variability of defeat and entrapment highlighting that repeated measurement of defeat and entrapment-preferably in real time-is necessary in order to adequately capture the actual empirical relations of these variables and not to overlook significant within-person variability. Further research-especially within clinical samples-seems warranted.

Short defeat and entrapment scale: A psychometric investigation in three German samples

BACKGROUND

The present study aimed to validate the German version of the Short Defeat and Entrapment Scale (SDES).

METHODS

Validity and reliability were established in an online (N = 480), an outpatient (N = 277) and an inpatient sample (N = 296). Statistical analyses included confirmatory factor analyses (CFA) and group differences in defeat and entrapment.

RESULTS

For the online and the inpatient sample, the CFA indicated a two-factor solution, whereas for the outpatient sample both one- and two-factor solutions fitted the data equally well. Scale properties for the two-factor solution (defeat and entrapment subscale) were excellent. Thus, further analyses were based on this solution. For the online and the outpatient sample, suicidal ideators and suicide attempters scored significantly higher in defeat and entrapment than non-ideators and non-attempters.

LIMITATIONS

Limiting factors of the study were the different measures across the samples and the cross-sectional design of the study.

CONCLUSION

Though results were partly mixed, we found support for a two-factor solution of the instrument showing excellent psychometric properties in all three samples. The two-factor solution is further expected to have higher clinical utility than a one-factor solution. Suicidal ideators and suicide attempters in the online and outpatient sample showed higher scores in defeat and entrapment than non-ideators and non-attempters, emphasizing these two concepts as predictors for suicidal ideation. All in all, the present study supports the general validity and reliability of the SDES. However, future investigations based on prospective data are warranted.

Mediation effects of depression and anxiety on social support and quality of life among caregivers of persons with severe burns injury

OBJECTIVE

Caregiving is associated with several psychosocial challenges including stress, depression and anxiety. These challenges have been found to have significant negative impacts on the health and wellbeing of caregivers, but the mechanisms of these effects are poorly understood. This study examined whether depression and anxiety serve as mediators between social support and quality of life caregivers of persons with severe burns injury.

RESULTS

A sample of 100 caregivers of persons with severe burns injury were administered questionnaires to assess their depression, anxiety, social support and quality of life. Findings show that depression and anxiety were negatively correlated with quality of life whereas social support was positively correlated with quality of life. Results further showed that only depression significantly mediated the link between social support and quality of life among the caregivers. These findings emphasize the need to screen caregivers for common mental health problems and provide them support in the caregiving process to promote their health and wellbeing.

Feelings of Entrapment and Defeat Mediate the Association Between Self-Esteem and Depression Among Transgender Women Sex Workers in China

BACKGROUND

Transgender women sex workers have a high prevalence of depression. Low self-esteem and subsequent involuntary subordination (characterized by feelings of defeat and entrapment) are well-documented risk factors for depression. The object of the present study was to investigate the mediating effect of feelings of entrapment and defeat on the relationship between self-esteem and depression among transgender women sex workers in China.

METHODS

A cross-sectional study was conducted in Shenyang and Guangzhou in 2017. Participants were 198 transgender women sex workers who completed a structured questionnaire assessing background characteristics, self-esteem, feelings of entrapment and defeat, and depression. Linear regression was used to test the mediation hypotheses.

RESULTS

Of participants, 25.25% exhibited high levels of depression. Self-esteem scores were negatively correlated with depression scores (r = -0.54, p < 0.05, R 2 adj = 0.23), defeat scores (r = -1.68, p < 0.05, R 2 adj = 0.31), and entrapment scores (r = -1.67, p < 0.05, R 2 adj = 0.25). In the mediation hypothesis model, entrapment (r = 0.21, p < 0.05) and defeat (r = 0.08, p < 0.05) had a complete mediating effect on the relationship between self-esteem (Spearman's r = -0.06, p = 0.36) and depression (R 2 adj = 0.61).

CONCLUSION

Feelings of entrapment and defeat mediated the association between self-esteem and depression. More focus is needed on monitoring feelings of defeat and entrapment among transgender women sex workers to mitigate the risk of depression.

Assessment of Striatal Dopamine Transporter Binding in Individuals With Major Depressive Disorder: In Vivo Positron Emission Tomography and Postmortem Evidence

IMPORTANCE

Major depressive disorder (MDD) might involve dopamine (DA) reductions. The DA transporter (DAT) regulates DA clearance and neurotransmission and is sensitive to DA levels, with preclinical studies (including those involving inescapable stressors) showing that DAT density decreases when DA signaling is reduced. Despite preclinical data, evidence of reduced DAT in MDD is inconclusive.

OBJECTIVE

Using a highly selective DAT positron emission tomography (PET) tracer ([11C] altropane), DAT availability was probed in individuals with MDD who were not taking medication. Levels of DAT expression were also evaluated in postmortem tissues from donors with MDD who died by suicide.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional PET study was conducted at McLean Hospital (Belmont, Massachusetts) and Massachusetts General Hospital (Boston) and enrolled consecutive individuals with MDD who were not taking medication and demographically matched healthy controls between January 2012 and March 2014. Brain tissues were obtained from the Douglas-Bell Canada Brain Bank. For the PET component, 25 individuals with current MDD who were not taking medication and 23 healthy controls recruited from McLean Hospital were included (all provided usable data). For the postmortem component, 15 individuals with depression and 14 healthy controls were considered.

INTERVENTION

PET scan.

MAIN OUTCOMES AND MEASURES

Striatal and midbrain DAT binding potential was assessed. For the postmortem component, tyrosine hydroxylase and DAT levels were evaluated using Western blots.

RESULTS

Compared with 23 healthy controls (13 women [56.5%]; mean [SD] age, 26.49 [7.26] years), 25 individuals with MDD (19 women [76.0%]; mean [SD] age, 26.52 [5.92] years) showed significantly lower in vivo DAT availability in the bilateral putamen and ventral tegmental area (Cohen d range, -0.62 to -0.71), and both reductions were exacerbated with increasing numbers of depressive episodes. Unlike healthy controls, the MDD group failed to show an age-associated reduction in striatal DAT availability, with young individuals with MDD being indistinguishable from older healthy controls. Moreover, DAT availability in the ventral tegmental area was lowest in individuals with MDD who reported feeling trapped in stressful circumstances. Lower DAT levels (and tyrosine hydroxylase) in the putamen of MDD compared with healthy controls were replicated in postmortem analyses (Cohen d range, -0.92 to -1.15).

CONCLUSIONS AND RELEVANCE

Major depressive disorder, particularly with recurring episodes, is characterized by decreased striatal DAT expression, which might reflect a compensatory downregulation due to low DA signaling within mesolimbic pathways.

Exploring the psychology of suicidal ideation: A theory driven network analysis

Two leading theories within the field of suicide prevention are the interpersonal psychological theory of suicidal behaviour (IPT) and the integrated motivational-volitional (IMV) model. The IPT posits that suicidal thoughts emerge from high levels of perceived burdensomeness and thwarted belongingness. The IMV model is a multivariate framework that conceptualizes defeat and entrapment as key drivers of suicide ideation. We applied network analysis to cross-sectional data collected as part of the Scottish Wellbeing Study, in which a nationally representative sample of 3508 young adults (18-34 years) completed a battery of psychological measures. Network analysis can help us to understand how the different theoretical components interact and how they relate to suicide ideation. Within a network that included only the core factors from both models, internal entrapment and perceived burdensomeness were most strongly related to suicide ideation. The core constructs defeat, external entrapment and thwarted belonginess were mainly related to other factors than suicide ideation. Within the network of all available psychological factors, 12 of the 20 factors were uniquely related to suicide ideation, with perceived burdensomeness, internal entrapment, depressive symptoms and history of suicide ideation explaining the most variance. None of the factors was isolated, and we identified four larger clusters: mental wellbeing, interpersonal needs, personality, and suicide-related factors. Overall, the results suggest that relationships between suicide ideation and psychological risk factors are complex, with some factors contributing direct risk, and others having indirect impact.

An Examination of Social Comparison and Suicide Ideation Through the Lens of the Integrated Motivational-Volitional Model of Suicidal Behavior

We aimed to investigate whether negative social comparisons are associated with key components of the integrated motivational-volitional (IMV) model of suicidal behavior. Specifically, we investigated the relationship between negative social comparisons, suicide ideation, defeat, entrapment, socially prescribed perfectionism, and resilience. Adult participants (N = 422) completed an online survey comprised of a range of psychological measures. An initial regression analysis indicated that negative social comparisons were associated with suicide ideation. Three mediation models were tested based on the IMV model, all controlling for depressive symptoms. In the first, social comparison partially mediated the relationship between socially prescribed perfectionism and defeat. In the second, defeat mediated the relationship between negative social comparisons and entrapment, and resilience moderated the relationship when defeat was high. In the final model, entrapment mediated the relationship between defeat and suicide ideation, with resilience moderating this relationship when entrapment was high. These findings are novel and lend support to the IMV model. The clinical implications include highlighting the importance of targeting resilience given its potential association with defeat and entrapment.

From ideation to action: Differentiating between those who think about suicide and those who attempt suicide in a national study of young adults

BACKGROUND

Although many suicide risk factors have been identified, there is still relatively little known about the factors that differentiate those who think about suicide from those who make a suicide attempt.

AIMS

Using the integrated motivational-volitional model (IMV) of suicidal behaviour as a framework, this study hypothesised that (i) motivational and volitional phase factors would differentiate non-suicidal controls from those who had a history of suicidal ideation or suicide attempts, and (ii) within a multivariable model only volitional phase factors would differentiate between those who had a history of suicidal ideation and those who had attempted suicide.

METHOD

The Scottish Wellbeing Study (n = 3508) is a nationally representative study of young people (18-34 years) recruited throughout Scotland. Using multinomial regression analysis, three groups (non-suicidal control (n = 2534), lifetime suicide ideation (n = 498) and lifetime suicide attempt (n = 403) groups) were compared on motivational and volitional phase variables.

RESULTS

Consistent with the IMV model, motivational and volitional phase variables differentiated the control group from both the ideation and attempt groups. Only volitional phase variables differentiated between the suicide attempt group and the suicidal ideation group in the multivariable model; with those reporting a suicide attempt being higher on acquired capability, mental imagery about death, impulsivity, and being more likely to know a friend who had made a suicide attempt. Having a family member or friend die by suicide or a family member attempt suicide did not differentiate between the groups.

LIMITATIONS

The findings were based on cross-sectional data derived from self-report measures.

CONCLUSIONS

These findings provide further support for the IMV model, and highlight potential targets for clinical intervention.

Insomnia and Nightmares as Markers of Risk for Suicidal Ideation in Young People: Investigating the Role of Defeat and Entrapment

STUDY OBJECTIVES

Although converging evidence has identified sleep problems as robust predictors of suicidal ideation in young people, the psychological processes driving these associations are not yet known. The current study aimed to test predictions, informed by the Integrated Motivational-Volitional (IMV) Model of Suicidal Behavior, concerning the role of feelings of defeat and entrapment within the sleep-suicide relationship.

METHODS

Volunteers aged 15 to 17 years (n = 1,045) from Scottish secondary schools completed an anonymous self-report survey assessing insomnia symptoms, nightmares, suicidal ideation, depressive symptomology, and feelings of defeat and entrapment.

RESULTS

Both insomnia symptoms and nightmares were associated with an increased likelihood of reporting suicidal ideation (independent of depression). Perceptions of both defeat and entrapment were elevated in young people who reported clinically salient insomnia and/or nightmares, relative to those who did not. The relationship between insomnia and suicidal ideation was fully mediated by perceptions of defeat and entrapment, whereas nightmares were indirectly associated with suicidal ideation through perceptions of defeat and entrapment.

CONCLUSIONS

Taken together, these findings provide novel insights into the psychological mechanisms linking sleep disturbance and suicidality by highlighting the role of defeat and entrapment. Clinically, these findings have the potential to improve suicide risk assessment and prevention in young people experiencing difficulties with their sleep.

Assessing Performance on an Evaluated Speaking Task

Abstract. Coping with social stress involves cognitive perceptions and the activation of several physiological mechanisms. Our main purpose was to examine how psychological factors such as cognitive appraisal, and particularly self-efficacy, may affect psychophysiological reactivity to social stress and young people’s performance on an evaluated speaking task. Thirty-five university students (18 men and 17 women) were exposed to the Trier Social Stress Test (TSST) and a control condition in a counterbalanced order. Self-efficacy, several dimensions of trait anxiety related to social evaluation, and changes in state anxiety were assessed. Additionally, heart rate and heart rate variability (HRV) were analyzed by means of R-R and r-MSSD parameters, respectively. The results indicate that a positive self-assessment of their own ability to overcome a social threat was related to the predominance of vagal tone and better performance. However, cardiac reactivity was not related to the quality of the performance displayed. In addition, some dimensions of trait anxiety, such as cognitive anxiety and test evaluation anxiety, were negatively associated with self-efficacy and performance. These findings emphasize the relevance of self-efficacy, a key component of cognitive appraisal, in explaining psychophysiological reactivity to social stress. Furthermore, they highlight the importance of some personality characteristics, such as social evaluation anxiety, in explaining performance in specifically related stressful situations, regardless of autonomic activation.

Defeat and Entrapment in Bipolar Disorder: Exploring the Relationship with Suicidal Ideation from a Psychological Theoretical Perspective

Contemporary psychological theoretical models of suicide hypothesize that defeat and entrapment underlie the development of suicidal ideation. This hypothesis has never been tested in people who experience bipolar disorder. Regression analysis revealed that defeat and entrapment significantly predicted suicidal ideation at 4-month follow-up. The relationship between defeat and suicidal ideation was mediated by total entrapment and internal entrapment, but not external entrapment. Results suggest that perceived defeat and entrapment underlie the development of prospective suicidal ideation in bipolar disorder. Findings could potentially improve the assessment of suicide risk in people who experience bipolar disorder.

Defeat and entrapment: more than meets the eye? Applying network analysis to estimate dimensions of highly correlated constructs

BACKGROUND

Defeat and entrapment have been shown to be of central relevance to the development of different disorders. However, it remains unclear whether they represent two distinct constructs or one overall latent variable. One reason for the unclarity is that traditional factor analytic techniques have trouble estimating the right number of clusters in highly correlated data. In this study, we applied a novel approach based on network analysis that can deal with correlated data to establish whether defeat and entrapment are best thought of as one or multiple constructs.

METHODS

Explanatory graph analysis was used to estimate the number of dimensions within the 32 items that make up the defeat and entrapment scales in two samples: an online community sample of 480 participants, and a clinical sample of 147 inpatients admitted to a psychiatric hospital after a suicidal attempt or severe suicidal crisis. Confirmatory Factor analysis (CFA) was used to test whether the proposed structure fits the data.

RESULTS

In both samples, bootstrapped exploratory graph analysis suggested that the defeat and entrapment items belonged to different dimensions. Within the entrapment items, two separate dimensions were detected, labelled internal and external entrapment. Defeat appeared to be multifaceted only in the online sample. When comparing the CFA outcomes of the one, two, three and four factor models, the one factor model was preferred.

CONCLUSIONS

Defeat and entrapment can be viewed as distinct, yet, highly associated constructs. Thus, although replication is needed, results are in line with theories differentiating between these two constructs.

A meta-analysis of perceptions of defeat and entrapment in depression, anxiety problems, posttraumatic stress disorder, and suicidality

BACKGROUND

There is a burgeoning literature examining perceptions of being defeated or trapped in different psychiatric disorders. The disorders most frequently examined to date are depression, anxiety problems, posttraumatic stress disorder (PTSD), and suicidality.

AIMS

To quantify the size and consistency of perceptions of defeat and entrapment in depression, anxiety problems, PTSD and suicidality, test for differences across psychiatric disorders, and examine potential moderators and publication bias.

METHOD

Random-effects meta-analyses based on Pearson's correlation coefficient r.

RESULTS

Forty studies were included in the meta-analysis (n = 10,072). Perceptions of defeat and entrapment were strong (around r = 0.60) and similar in size across all four psychiatric disorders. Perceptions of defeat were particularly strong in depression (r = 0.73). There was no between-study heterogeneity; therefore moderator analyses were conducted in an exploratory fashion. There was no evidence of publication bias.

LIMITATIONS

Analyses were cross-sectional, which precludes establishing temporal precedence or causality. Some of the meta-analyses were based on relatively small numbers of effect sizes, which may limit their generalisability.

CONCLUSIONS

Perceptions of defeat and entrapment are clinically important in depression, anxiety problems, PTSD, and suicidality. Similar-sized, strong relationships across four different psychiatric disorders could suggest that perceptions of defeat and entrapment are transdiagnostic constructs. The results suggest that clinicians and researchers need to become more aware of perceptions of defeat and entrapment.

A comparison of inpatients with anxious depression to those with nonanxious depression

Anxiety symptoms are common for patients with major depressive disorder (MDD). Anxious depression has been considered MDD with high levels of anxiety symptoms. The objective of this study was to investigate the factors associated with anxious depression for Chinese inpatients with MDD. A total of 174 acutely ill patients were enrolled. Baseline demographic variables, suicide risk, depression severity, quality of life (QOL), and daily functional impairment were assessed. Those MDD patients with a 17-item Hamilton Depression Rating Scale (HAMD-17) anxiety/somatization factor score≥7 were defined as anxious depression. Logistic regression was employed to examine the factors associated with anxious depression. One hundred and forty-one (81.0%) of the subjects reported anxious depression. Patients with anxious depression were more likely to have melancholic features, to be older, to experience more severe depression, to be at greater risk of suicide, to have more pain, poorer quality of life, and more severe functional impairment. Anxious depression is common in inpatients with MDD. These findings suggest that anxious depression significantly differs from nonanxious depression on several clinically relevant variables. These data add to a growing body of evidence that anxious depression is a more complex presentation of depression.
