Chronic pain and the interpersonal theory of suicide

Grieving "The Death of Possibility": Memorable Messages of (Dis)Enfranchised Loss in Invisible, Physical Illness

Guided by theories of communicative disenfranchisement (TCD) and memorable messages (ToMM), this study analyzes 60 open-ended survey responses detailing experiences of grief following the onset of invisible, physical illness (e.g., chronic overlapping pain conditions, autoimmune rheumatic diseases). Employing reflexive thematic analysis, we identify (1) illness-related losses that are disenfranchised by discourses surrounding grief and (2) opportunities to enfranchise these losses via memorable messages. Situated at two points in time, before and after the onset of illness, we identify disenfranchised losses as what once was (e.g., physical [in]dependence, relational connection, images of self, and trust in institutions) and what will never be (e.g., family planning and career dreams). Next, we identify opportunities to disrupt this disenfranchisement through memorable messages of presence (e.g., nonverbal acknowledgment and verbal expressions of belief) and finding the fit (e.g., physical restructuring and community connection). In doing so, we extend theoretical understanding of both memorable messages, in the form that they can take (of experience) and as points of (dis)enfranchisement, and communicative (dis)enfranchisement. This study contributes to a growing body of health communication research on disenfranchising experiences in chronic illness by highlighting a resulting experience of illness not often talked about - illness-related loss and its grief process. Theoretical and practical implications, as well as limitations and future directions, are discussed.

Thwarted Belongingness and Suicide Risk in Primary Care: Perceived Burdensomeness and Psychache as Mediators

Suicide is a significant public health concern, particularly among primary care patients, given that many individuals who die by suicide visit their primary care provider in the months prior to their death. We examined constructs from two prominent theories of suicide, the interpersonal and psychache theories, including thwarted belongingness, perceived burdensomeness, and psychache. Among our sample (n = 224) of patients, perceived burdensomeness and psychache, individually and in serial, mediated the relation between thwarted belongingness and suicidal behavior. Thwarted belongingness was associated with greater perceived burdensomeness and, in turn, with more psychache and increased suicide risk. Our results elucidate the associations between the interpersonal and psychache theories of suicide. Clinical strategies that may reduce thwarted interpersonal needs and psychache, and which are appropriate for medical settings, are discussed.

Drug Safety and Suicidality Risk of Chronic Pain Medications

Chronic pain is one of the main leading causes of disability in the world at present. A variety in the symptomatology, intensity and duration of this phenomenon has led to an ever-increasing demand of pharmacological treatment and relief. This demand for medication, ranging from well-known groups, such as antidepressants and benzodiazepines, to more novel drugs, was followed by a rise in safety concerns of such treatment options. The validity, frequency, and diversity of such concerns are discussed in this paper, as well as their possible effect on future prescription practices. A specific caution is provided towards the psychological safety and toll of these medications, regarding suicidality and suicidal ideation. Most significantly, this paper highlights the importance of pharmacovigilance and underscores the necessity of surveillance programs when considering chronic pain medication.

Prevalence of suicidal behavior in patients with chronic pain: a systematic review and meta-analysis of observational studies

Objective

Chronic pain is a leading cause of disability, severely impairing an individual's daily activity and quality of life. In addition, this condition may contribute to suicidal thoughts by leading to neuropsychological impairments, a perceived lack of meaning in life, and pain-related catastrophizing. This systematic review aimed to comprehensively investigate the prevalence and associated factors of suicidal behaviors (SBs) including suicidal ideation (SI) and suicide attempt (SA) or its complete, in individuals with chronic pain.

Methods

Five electronic databases were searched up to October 4, 2022. Only observational studies investigating the prevalence of SB in individuals with chronic pain were included. The methodological quality of the included studies was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. A meta-analysis was conducted to quantify the prevalence of SB in the population, and the command "Metaprop" was used in STATA/MP 16. In addition, factors explaining the association between chronic pain and SB identified through regression analysis were investigated.

Results

A total of 19 studies were included in this review (N = 3,312,343). The pooled lifetime prevalence of SI and SA was 28.90% (95% confidence interval, 17.95 to 41.26%) and 10.83% (5.72 to 17.30%), respectively, in a mixed sample comprising various chronic pain conditions. Importantly, the pooled prevalence of past 2-week SI was as high as 25.87% (18.09 to 34.50%). The methodological quality of the included studies was not optimal, and studies using validated SB assessment tools were lacking. Potential protective factors against SB in this population included pain coping and self-efficacy, older age, certain race/ethnicity groups, and marriage.

Conclusion

This systematic review and meta-analysis demonstrated the high prevalence of SB in individuals with chronic pain. Specifically, around 1 in 4 individuals with chronic pain had SI within the last 2 weeks. However, there was considerable heterogeneity in the pooled prevalence of SB in this population.

The Relationship Between Chronic Pain, Depression, Psychosocial Factors, and Suicidality in Adolescents

BACKGROUND

Chronic pain in youth is often associated with social conflict, depression, and suicidality. The interpersonal theory of suicide posits that there are psychosocial factors, such as peer victimization and lack of fear of pain, that may also influence suicidality.

OBJECTIVES

The objective of this study was to determine whether depressive symptoms, peer victimization, and lack of fear of pain predict suicidality in adolescents with chronic pain. It was hypothesized that higher levels of depressive symptoms and peer victimization, and lower levels of fear of pain, would predict a higher lifetime prevalence of suicidality.

METHODS

Participants consisted of 184 youth with primary chronic pain conditions (10 to 18 y, M = 14.27 y). Measures included diagnostic clinical interviews assessing suicidality and self-report questionnaires assessing depressive symptoms, peer victimization, and fear of pain.

RESULTS

Forty-two (22.8%) participants reported suicidality. Regression analyses demonstrated that the occurrence of suicidality was associated with higher rates of depressive symptoms (β = 1.03, P = 0.020, 95% CI: 1.01, 1.06) and peer victimization (β = 2.23, P < 0.05, 95% CI: 1.07, 4.63), though there was no association between lower fear of pain and suicidality.

DISCUSSION

These results suggest that depressive symptoms and peer victimization are significant predictors of suicidality in adolescents with chronic pain; however, lower fear of pain was not shown to be a significant predictor. Given these findings, depression and peer victimization should be further explored and considered in the design and implementation of prevention and early intervention strategies that target chronic pain and suicidality in youth.

Differences in suicide risk correlates and history of suicide ideation and attempts as a function of disability type

BACKGROUND

Disability status is associated with correlates of suicide risk (perceived burdensomeness, thwarted belongingness, negative future disposition, felt stigma, suicidal ideation, and suicide attempts).

AIMS

This study aimed to examine whether suicide-related correlates differ significantly as a function of disability type.

METHODS

Individuals with mobility and vision disabilities (N = 102) completed semistructured interviews and online-based questionnaires. Analysis of variance/analysis of covaiance and Fisher's exact tests were conducted to examine whether mean levels of suicide-related correlates differed significantly between individuals with blindness/low vision (n = 63) versus mobility-related (n = 39) disabilities.

RESULTS

No significant between-group differences were observed for most outcomes; however, individuals with vision disabilities reported higher mean levels of felt stigma and positive future disposition than those with mobility-related disabilities.

LIMITATIONS

The limited representation of disabilities among participants precludes generalization to individuals with other forms of disability and the cross-sectional design prevents inference about causality.

CONCLUSIONS

Interventions targeting cognitive processes that underlie suicide risk may be applicable to people with mobility and vision disabilities.

Long COVID and mental health correlates: a new chronic condition fits existing patterns

Background

Emerging Long COVID research indicates the condition has major population health consequence. Other chronic conditions have previously been associated with functional and mental health challenges - including depression, anxiety, post-traumatic stress disorder (PTSD), suicide ideation, substance use and lower life satisfaction.

Methods

This study explores correlations between self-reported Long COVID, functional and mental health challenges among a random community-based sample of people (n = 655) aged 20-50 years who contracted COVID-19 prior to vaccination in a Texas county. A random sample of eligible participants was mailed a link to participate in a semi-structured questionnaire. Participant responses, including open-ended responses regarding their experience following COVID-19, were paired with health system data.

Results

Long COVID was associated with increased presence of depression (13% increase), anxiety (28% increase), suicide ideation (10% increase), PTSD (20% increase), and decreased life satisfaction and daily functioning. Structural equation modeling, controlling for sociodemographic variables and imposing a theoretical framework from existing chronic disease research, demonstrated correlations between Long COVID and higher PTSD, suicide ideation and lower life satisfaction were mediated by higher daily functional challenges and common mental disorders.

Conclusions

Basic and applied, interdisciplinary research is urgently needed to characterize the population-based response to the new challenge of Long COVID.

Psychometric Properties of the Interpersonal Needs Questionnaire-15 in Spanish Adolescents

BACKGROUND

Thwarted Belongingness (TB) and Perceived Burdensomeness (PB) are considered risk factors of suicide behavior in the Interpersonal Theory of Suicide and constitute the main factors of the Interpersonal Needs Questionnaire-INQ.

AIMS

The present study analyzes the internal consistency, construct validity, and invariance across sex and age of the INQ-15, which comprises two subscales, in a sample of Spanish community adolescents.

METHODS

Participants were 1,536 adolescents from 12 to 19 years old. The INQ-15, the total number of non-suicidal self-injuries (NSSI), the Hopelessness Scale, and the Purpose in Life Test-Adolescents (PIL-A) were used.

RESULTS

The INQ-15 showed good internal consistency for TB ( ω ¯ = 0.88) and PB ( ω ¯ = 0.78) subscales and construct and concurrent/discriminant validity in the whole sample. Both the PB and TB subscales showed a good fit { S B χ 2 ( 9 ) = 6.448, p = 0.694, CFI = 1.000, RMSEA = 0.000 [90% CI (0.000, 0.022)] and S B χ 2 ( 27 ) = 248.973, p = 0.000, CFI = 0.922, RMSEA = 0.073 [90% CI (0.065, 0.082)]}, respectively. Regarding the invariance analyses, we found (1) non-invariance in the PB subscale across sex groups and metric, scalar, and stric invariance across age groups, and (2) that it was not possible to perform the invariance analysis for the TB subscale across both sex and age because the fit was not adequate for both boys and 12-15 years old groups. Positive and significant relationships were found between the INQ-15 subscales and hopelessness and NSSI frequency, and negative and significant correlations with meaning in life.

CONCLUSIONS

The INQ-15 is a valid instrument for assessing TB and PB in Spanish adolescents. Future studies should analyze the invariance of this instrument in adolescents across sex and age.

Patient Perceptions of Physician Burden in the Treatment of Chronic Pain

While patient perceptions of burden to caregivers is of recognized clinical significance among people with chronic pain, perceived burden to treating physicians has not been studied. This study examined how people with chronic pain perceived levels of medical evidence (low vs high) and pain severity (4,6,8/10) to influence physician burden and how burden then mediated expected clinical judgments. 476 people with chronic pain read vignettes describing a hypothetical patient with varying levels of medical evidence and pain severity from the perspective of a treating physician, rated the burden that patient care would pose, and made a range of clinical judgments. The effect of pain severity on clinical judgments was expected to interact with medical evidence and be conditionally mediated by burden. Although no associations with burden were found for the pain severity x medical evidence interaction or for pain severity alone, low levels of supporting medical evidence yielded higher burden ratings. Burden significantly mediated medical evidence effects on judgments of symptom credibility, clinical improvement, and psychosocial dysfunction. Results indicate that perceived physician burden negatively influenced judgments of patients with chronic pain, beyond the direct effects of medical evidence. Implications are discussed for clinical practice, as well as future research. PERSPECTIVE: : People with chronic pain expect physicians to view the care of patients without supporting medical evidence as burdensome. Higher burden is associated with less symptom credibility, more psychosocial dysfunction, and less treatment benefit. Perceived physician burden appears to impact how patients approach treatment, with potentially adverse implications for clinical practice.

Community Perspectives on Patient Credibility and Provider Burden in the Treatment of Chronic Pain

OBJECTIVE

This study examined factors influencing lay perceptions of a provider's clinical burden in providing care to a person with chronic pain.

DESIGN

In a between-subjects design that varied three levels of pain severity (4-6-8/10) with two levels of medical evidence (low/high), participants rated the credibility of pain reported by a hypothetical patient and psychosocial factors expected to mediate the effects of evidence and severity on a provider's burden of care.

SETTING

A randomized vignette study in which community participants were recruited via Amazon Mechanical Turk.

SUBJECTS

337 community participants.

METHODS

Using a Qualtrics platform, participants read one of six vignettes describing a hypothetical patient with varying levels of medical evidence and pain severity, and then rated perceived pain severity, pain credibility, psychosocial variables, and burden.

RESULTS

Serial mediation models accounted for all effects of medical evidence and pain severity on burden. Low medical evidence was associated with increased burden, as mediated through lower pain credibility and greater concerns about patient depression, opioid abuse, and learning pain management. Higher levels of reported pain severity were associated with increased burden, as mediated through greater pain discounting and concerns about opioid abuse.

CONCLUSIONS

The lay public is skeptical of chronic pain that is not supported by medical evidence or is reported at high levels of severity, raising concerns about psychosocial complications and drug seeking and expectations of higher burden of care. Such negative stereotypes can pose obstacles to people seeking necessary care if they or others develop a chronic pain condition.

A Preliminary Study of Provider Burden in the Treatment of Chronic Pain: Perspectives of Physicians and People with Chronic Pain

This study compared perceptions of the burden of patient care and associated clinical judgments between physicians and people with chronic pain (PWCP) in a 2 × 3 × 2 between-subjects design that varied participant type, patient-reported pain severity (4/6-8/10), and supporting medical evidence (low/high). One hundred and nine physicians and 476 American Chronic Pain Association members were randomly assigned to 1 of 6 conditions. Respondents estimated the clinical burden they would assume as the treating physician of a hypothetical patient with chronic low back pain, and made clinical judgments regarding that patient. Physician burden ratings were significantly higher than PWCP ratings, and clinical impressions (eg, trust in pain report, medical attribution) and management concerns (eg, opioid abuse risk) were relatively less favorable. Neither pain severity nor medical evidence affected burden ratings significantly. High medical evidence was associated with more favorable clinical impressions; higher pain severity led to more discounting of patient pain reports. Burden was significantly correlated with a range of clinical judgments. Results indicate that physicians and PWCP differ in their perceptions of provider burden and related clinical judgments in ways that could impact treatment collaboration. Further research is needed that examines provider burden in actual clinical practice. PERSPECTIVE: Physicians and people with chronic pain (PWCP) estimated the clinical burden of patient care and made judgments about a hypothetical patient with chronic pain. Physician burden ratings were higher and clinical judgments less favorable, relative to PWCP respondents. These differences could impact treatment collaboration and merit study in clinical practice.

The Relationship between Suicidality and Socio-Demographic Variables, Physical Disorders, and Psychiatric Disorders: Results from the Singapore Mental Health Study 2016

Suicidality encompasses suicidal ideation, plans, and attempts. This paper aims to establish associations between suicidality and sociodemographic variables, physical disorders, and psychiatric disorders. The Singapore Mental Health Study 2016 was a population-level epidemiological survey, which determined the prevalence of physical disorders, psychiatric disorders, and suicidality. Questionnaires were used to determine socio-demographic information. A total of 6216 respondents were interviewed. Lifetime prevalence of suicidal ideation, planning, and attempts were 7.8%, 1.6%, and 1.6%, respectively. All components of suicidality were more likely in those with major depressive disorder, bipolar disorder, generalized anxiety disorder, alcohol use disorder, and chronic pain. Suicidal ideation and attempts were more likely in those with diabetes. Age above 65, being male, and a monthly household income of ≥ SGD 10,000 were associated with a lower likelihood of suicidal ideation. These findings indicate that there are high-risk groups for whom suicidality is a concern, and for whom interventions may be needed.

Risk factors for suicide in chronic fatigue syndrome

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) includes symptoms such as post-exertional malaise, unrefreshing sleep, and cognitive impairments. Several studies suggest these patients have an increased risk of suicidal ideation and early mortality, although few have published in this area. This study explores risk factors for suicide among 64 individuals with ME/CFS using archival data, 17 of which died from suicide. Results indicated an increased risk of suicide for those for those utilizing the label CFS, for those with limited overall functioning, and for those without comorbid illnesses. Findings suggest that stigma and functional impairments limit access to care and social supports.

Understanding suicidal ideation and behaviour in individuals with chronic pain: a review of the role of novel transdiagnostic psychological factors

Individuals with chronic pain are at an elevated risk of suicide, yet psychosocial factors that might be involved in increasing or decreasing vulnerability for suicidal ideation and behaviour have received little attention. Extant literature on the topic of suicide in individuals with chronic pain incorporates only a few of the wide array of known vulnerability and protective factors. This Review focuses on transdiagnostic psychological processes, (ie, those of relevance for both chronic pain and suicide). We reviewed a selection of published literature on chronic pain and suicide, concentrating on previously unexplored and underexplored lines of research, including future orientation, mental imagery, and psychological flexibility. A greater degree of crosspollination between the fields of chronic pain and suicide research is required to progress our understanding of why some people with chronic pain become suicidal and others do not.

Pain catastrophizing as a predictor of suicidal ideation in chronic pain patients with an opiate prescription

Chronic pain and opioid use are associated with increased risk for suicidal ideation and behaviors (SIB) in cross-sectional studies, particularly among individuals who catastrophize about their pain. This study examined the longitudinal association between two styles of pain coping, catastrophizing and hoping/praying, as predictors of subsequent SIB, as well as possible mediators of this association among patients with chronic pain receiving long-term opioid therapy. Participants (n = 496) were adults with chronic nonmalignant pain on long-term opioid therapy who did not develop an opioid use disorder. Participants were assessed for pain coping, suicidal ideation, depression, social support and pain interference at baseline, and were reassessed for SI, depression, and pain interference at 6- and 12-month follow-ups. Catastrophizing was a significant predictor of increased subsequent SIB, whereas hoping/praying did not protect against future SIB. The relationship between catastrophizing and future SIB was mediated by depression, but not social support or pain interference. In conclusion, catastrophizing was an important predictor of subsequent SIB due to its effect on increasing depression among patients with chronic nonmalignant pain receiving long-term opioid therapy. Future research should explore the extent to which targeting catastrophizing reduces subsequent depression and suicide risk.

Negative Life Events (NLEs) Contributing to Psychological Distress, Pain, and Disability in a U.S. Military Sample

Introduction

The objective was to explore how negative life events (NLEs, e.g., litigation related to pain and disability, failing most recent physical fitness test, and financial difficulties) are related to pain coping and psychological adjustment to pain in active duty military personnel.

Materials and Methods

Data were gathered as part of the Evaluation of Suicidality, Cognitions, and Pain Experience study, a DoD-funded cross-sectional assessment of chronic pain and emotional coping among a cohort of military members. The investigators examined data from 147 respondents with complete survey and pain assessment data.

Results

The sample was active duty, male (62.6%), in a relationship or married (83.0%), and had children (68.7%). The majority of the sample endorsed zero NLEs (72.0%); 23.8% endorsed one NLE, 4.2% endorsed two NLEs, and no one endorsed all three NLEs. A significantly higher proportion of participants endorsing one or more NLEs reported suicidal ideation compared to those who reported no NLEs (χ2(2) = 8.61, p = 0.014). A higher number of endorsed NLEs coincided with higher symptom severity related to psychosocial distress (depression, thwarted belongingness, perceived burdensomeness, PTSD, and suicide cognitions) and poor pain coping (rumination, helplessness, and less acceptance of chronic pain).

Conclusions

Findings revealed that NLEs may impart a significant burden on military pain sufferers. Greater numbers of endorsed NLEs are associated with increased psychosocial distress and poor pain coping. Future longitudinal studies examining long-term psychosocial distress/poor pain coping as related to NLEs would help to elaborate the long-term consequences of NLEs on pain coping and psychosocial distress.

Suicide Risk in Persons with HIV/AIDS in South Korea: a Partial Test of the Interpersonal Theory of Suicide

PURPOSE

The high disease burden associated with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is linked to the elevated suicide risk in this population. Informed by the interpersonal theory of suicide, this study examined how and under which conditions depression is related to suicide risk in people living with HIV/AIDS.

METHODS

A total of 202 outpatients with HIV/AIDS participated in a cross-sectional and multi-center survey involving four university hospitals in South Korea. This self-reported survey included the Hospital Anxiety and Depression Scale, Interpersonal Needs Questionnaire, and Mini-International Neuropsychiatric Interview suicidality module.

RESULTS

Participants' mean age was 48.6 (SD = 13.4) and the majority was male (89.1%). The proportions of those at high, medium, and low suicide risk were 18.5%, 20%, and 15.4%, respectively. Depression was associated with suicide risk directly and indirectly by increasing perceived burdensomeness (PB) and the indirect effect of depression on suicide risk mediated by PB was contingent on the level of thwarted belongingness (TB). PB was associated with suicide risk even after controlling for depression, suggesting its independent effect on suicide risk.

CONCLUSIONS

PB and TB are potential mechanisms through which depression is associated with suicide risk, supporting the applicability of the interpersonal theory of suicide to understanding a complex interplay of risk factors in people with HIV/AIDS. Moreover, given the independent association of PB with suicide risk, as well as a protective effect of TB in suicide risk, monitoring and management of these factors should be included in the care of people with HIV/AIDS.

Suicidal ideation is associated with cardiovascular disease in a large, urban cohort of adults in the Southern Cone of Latin America

INTRODUCTION

To examine the relationship between suicidal ideation (SI) and cardiovascular disease (CVD) in the general adult population of four cities in the Southern Cone of Latin America (Argentina, Uruguay, Chile) and the role that depression, stressful life events (SLEs) and physical functional impairment may play in this association.

METHODS

A population-based cross-sectional study was conducted among 7524 adults between 35 and 74 years old, randomly selected. History of CVD included acute myocardial infarction, stroke and central or peripheral revascularization. SI in the past two weeks was measured using the last item of the Patient Health Questionnaire (PHQ-9), quality of life was assessed with the 12-item Short Form Survey (SF-12), and having experience of a SLE was determined by asking participants whether they had experienced at least one of a list of events in the past year. Multiple logistic regression was used to examine the association between SI and CVD overall and by sex.

RESULTS

The prevalence of SI was 8.3% (95% CI = 7.5, 9.0) and twice as high among women than men (11.1% vs. 5.1%). History of CVD was associated with almost twice the odds of SI (OR = 1.9, 95% CI = 1.5, 2.4). This association remained strong and significant after adjusting for potential confounders (OR = 1.8, 95% CI = 1.2, 2.7). Three additional models were tested to further adjust for depression severity, functional impairment, and SLEs separately. Adjustment for depression severity yielded no association between CVD and SI (OR = 1.1, 95% CI = 0.6, 1.7), adjustment for functional impairment yielded a marginal statistically significant association (OR = 1.5; 95% CI = 1.0, 2.4) and adjustment for SLE didn't modify either the magnitude or the statistical significance of the association.

CONCLUSIONS

There is a significant association between SI and CVD, particularly among women, which may be driven, at least in part, by depression and physical functional impairment.

Chronic pain and suicide risk: A comprehensive review

Death by suicide is one of the leading causes of mortality worldwide. Because individuals with chronic pain are at least twice as likely to report suicidal behaviors or to complete suicide, it is of utmost importance to target which risk factors contribute the most to increasing suicidality. This comprehensive review aims to provide an update on research advancements relating to the identification of potential risk factors for suicidality in individuals with chronic pain. Supporting the results of prior reviews, we found robust evidence that chronic pain itself, regardless of type, was an important independent risk factor for suicidality. The only sociodemographic factor found to be associated with suicidality in individuals with chronic pain was being unemployed/disabled. Depressive symptoms, anger problems, harmful habits (e.g. smoking, alcohol misuse, illicit drugs), childhood or adulthood adversities, and family history of depression/suicide were all also identified as general risk factors. Regarding pain-related factors, sleep problems, poorer perceived mental health, concurrent chronic pain conditions, and more frequent episodes of intermittent pain, were all found to be predictors of suicidality. Unexpectedly, pain characteristics (e.g. type, duration, and intensity/severity) and physical status (e.g. pain interference or disability) were not related to suicide risk. We also identified promising new psychosocial factors (e.g. mental defeat, pain catastrophizing, hopelessness, perceived burdensomeness and thwarted belongingness) associated with suicidality outcomes. A large number of these factors are amenable to change through targeted intervention, highlighting the importance of comprehensively assessing chronic pain patients at risk for suicide, while also incorporating a suicide prevention component into chronic pain management programs.

Validation of a Limitations in Daily Activities Scale for Chronic Pain

Limitations in physical function and participation are important domains of assessment in chronic pain. In 1995, the International Association for the Study of Pain distributed a self-report measure of functional limitations. Although the questionnaire has been used in research studies, it has never been subjected to a thorough investigation of its measurement properties. In this study, 941 patients with chronic pain completed the 16-item Limitations in Daily Activities Scale (LIDAS) at 2 pretreatment and 1 post-treatment assessment points. Individual item analysis favored a 13-item scale. This 13-item LIDAS had a confirmed 3-factor structure consisting of limitations in personal care, global participation, and specific tasks. Reliability analyses for the total scale (α = .90), as well as for each factor individually (αs = .82-.84), indicated good internal consistency, test-retest reliability (intraclass correlations = .65-.88 over varying time intervals), and responsiveness to change with treatment. LIDAS scores correlated as expected with measures of pain intensity, pain cognitions, and depression, as well as with other self-report and clinician-administered measures of functional performance. Using patient global ratings as anchors, a minimal clinically important difference of 5 points was established as a criterion for meaningful individual improvement after treatment. In conclusion, the LIDAS is a reliable, valid, and clinically relevant option for assessing limitations in physical function and participation in patients with chronic pain. PERSPECTIVE: Physical function and participation comprise a core dimension in the assessment of chronic pain. This study demonstrates that the LIDAS is a reliable and valid measure of this dimension, with good applicability for documenting clinically important change with treatment.

Perceived burdensomeness, thwarted belongingness and suicidal ideation in patients with fibromyalgia and healthy subjects: a cross-sectional study

Perceived burdensomeness and thwarted belongingness are key factors in the development of suicidal behaviors that have been frequently observed among patients with fibromyalgia. The aim of the present study was to compare these two factors in patients with fibromyalgia with and without suicidal ideation and healthy subjects. Secondary objectives were to evaluate the relationship between these two factors and the secondary variables included in the study, such as depression, sleep quality or the degree of marital adjustment. Perceived burdensomeness and thwarted belongingness were assessed with the Interpersonal Needs Questionnaire, depression and suicidal ideation with the Patients Health Questionnaire-9, suicidal risk with the Plutchik Suicide Risk scale, sleep with the Insomnia Severity Index, and marital adjustment with the Locke-Wallace Marital Adjustment scale. Questionnaire scores were compared with the Kruskal-Wallis test. 49 healthy subjects, 38 patients with fibromyalgia without suicidal ideation and 15 patients with fibromyalgia and suicidal ideations were included. Perceived burdensomeness scores were significantly higher in patients with suicidal ideation than in patients without suicidal ideation and controls; thwarted belongingness scores were significantly higher in patients with suicidal ideation than in controls. Marital adjustment was also significantly poor in patients with suicidal ideation than in patients without suicidal ideation and controls. Among patients with fibromyalgia, perceived burdensomeness seems to be strongly related with suicidal ideation, whereas thwarted belongingness seems to play a less relevant role at this respect. Poor marital adjustment could be related with depression.

The association between pain and suicidal behavior in an English national sample: The role of psychopathology

Pain has been linked with an increased risk of engaging in suicidal behavior. However, the role of common mental disorders (CMDs) and borderline personality disorder (BPD) traits in this association is largely unknown. This study was based on data from the 2007 Adult Psychiatric Morbidity Survey (N = 7403). Suicidal behavior referred to past 12-month suicidal ideation and suicide attempt. Pain was assessed in terms of the level of its interference with work activity in the past four weeks. BPD traits were assessed with the structured interview for DSM disorders questionnaire, and CMDs with the Clinical Interview Schedule Revised (CIS-R). Multivariate logistic regression and mediation analyses were conducted to analyze the association between pain and suicidal behavior, and the role of CMDs and BPD traits in this association. The prevalence of past 12-month suicidal ideation and suicide attempt increased from 2.7% to 11.5% and 0.2% to 2.4%, respectively, between no pain and extreme pain. Pain was found to be significantly associated with suicidal ideation (ORs = 1.61-2.92) and suicide attempt (ORs = 2.95-6.70). CMDs were significant mediators in the pain-suicidal behavior relationship but did not fully explain the association. BPD had little influence in this association. Assessing suicide risk in individuals with pain may be important for suicide prevention. Treating CMDs may reduce risk for suicide in these individuals but other factors leading to higher risk for suicidal behavior should also be investigated in future studies.

The interpersonal theory of suicide: A systematic review and meta-analysis of a decade of cross-national research

Over the past decade, the interpersonal theory of suicide has contributed to substantial advances in the scientific and clinical understanding of suicide and related conditions. The interpersonal theory of suicide posits that suicidal desire emerges when individuals experience intractable feelings of perceived burdensomeness and thwarted belongingness and near-lethal or lethal suicidal behavior occurs in the presence of suicidal desire and capability for suicide. A growing number of studies have tested these posited pathways in various samples; however, these findings have yet to be evaluated meta-analytically. This paper aimed to (a) conduct a systematic review of the unpublished and published, peer-reviewed literature examining the relationship between interpersonal theory constructs and suicidal thoughts and behaviors, (b) conduct meta-analyses testing the interpersonal theory hypotheses, and (c) evaluate the influence of various moderators on these relationships. Four electronic bibliographic databases were searched through the end of March, 2016: PubMed, Medline, PsycINFO, and Web of Science. Hypothesis-driven meta-analyses using random effects models were conducted using 122 distinct unpublished and published samples. Findings supported the interpersonal theory: the interaction between thwarted belongingness and perceived burdensomeness was significantly associated with suicidal ideation; and the interaction between thwarted belongingness, perceived burdensomeness, and capability for suicide was significantly related to a greater number of prior suicide attempts. However, effect sizes for these interactions were modest. Alternative configurations of theory variables were similarly useful for predicting suicide risk as theory-consistent pathways. We conclude with limitations and recommendations for the interpersonal theory as a framework for understanding the suicidal spectrum. (PsycINFO Database Record

The Influence of Traditional Culture and the Interpersonal Psychological Theory on Suicide Research in Korea

Korea has the highest suicide rate amongst the OECD countries. Yet, its research on suicidal behaviors has been primitive. While the Interpersonal Psychological Theory of Suicide has gained global attention, there has only been a few researches, which examined its applicability in Korea. In this article, we review the previous studies on suicide and examine the association between the Interpersonal Psychological Theory of Suicide and traditional Korean culture, with an emphasis on Collectivism and Confucianism. We propose that pathways to suicide might vary depending on cultural influences. Clinical implications and suggestions for future research will be discussed.

Self-perceived burden, perceived burdensomeness, and suicidal ideation in patients with chronic pain

Background: Self-perceived burden and perceived burdensomeness are two apparently related constructs that have arisen independently from research in physical and mental health, respectively. Although both are associated with suicidal ideation in individuals with chronic pain, they have yet to be examined concurrently in the same group of patients.

Aims: The aim of this study was to investigate the relationship between the two constructs and their differential prediction of suicidal ideation.

Methods: Participants were 260 outpatients of an interdisciplinary chronic pain treatment program. Each participant completed the Self-Perceived Burden Scale (SPBS), the Interpersonal Needs Questionnaire Perceived Burdensomeness Scale (INQPBS), the Beck Scale for Suicide Ideation, and the thoughts of self-harm item of the Patient Health Questionnaire-9.

Results: The SPBS and the INQPBS were both unifactorial measures with good internal consistency. They correlated significantly with one another (r = 0.50, P < 0.001), as well as with scores on the two measures of suicidal ideation (rs ranging from 0.29 to 0.62, Ps < 0.001). However, the INQPBS correlated more highly with suicidal ideation than did the SPBS. In regression analyses, the INQPBS predicted unique variance in suicidal ideation after adjusting for the SPBS. Conversely, the SPBS did not contribute uniquely when the INQPBS was entered first.

Conclusions: Patients with chronic pain who believe that they have become “a burden to others” are at increased risk for suicidal ideation. The conceptual similarities and differences between the constructs of self-perceived burden and perceived burdensomeness are reviewed to explain why perceived burdensomeness is the stronger predictor of this increased risk.

Investigation of the relationship between suicide probability in inpatients and their psychological symptoms and coping strategies

OBJECTIVE

To investigate the relationship between suicide probability and psychological symptoms and coping strategies in hospitalized patients with physical illness.

METHODS

This cross-sectional study was conducted from April to June 2014 in Bandirma State Hospital, Balikesir, Turkey. The sample of the study consisted of 470 inpatients who met the inclusion criteria and agreed to participate in the study. The data were collected with the Personal Information Form, Suicide Probability Scale, Brief Symptom Inventory and Ways of Coping with Stress Inventory.

RESULTS

In the study, 74.7% were at moderate risk for suicide, whereas 20.4% were at high risk for suicide. According to the stepwise multiple linear regression analysis, sub-dimensions of the Ways of Coping with Stress Inventory and Brief Symptom Inventory were the significant predictors of suicide probability.

CONCLUSION

The majority of the patients with physical illness were at risk for suicide probability. Individuals who had psychological symptoms and used maladaptive coping ways obtained significantly higher suicide probability scores.

Psychological and physical pain as predictors of suicide risk: evidence from clinical and neuroimaging findings

PURPOSE OF REVIEW

Suicide is a multidimensional clinical phenomenon with complex biological, social and psychological risk factors. Therefore, it is imperative for studies to focus on developing a unified understanding of suicide risk that integrates current clinical and neurobiological findings. A recent line of research has implicated different classifications of pain in understanding suicide risk, including the concepts of psychache and pain tolerance. Although psychache is defined as the experience of unbearable psychological pain, pain tolerance refers to the greatest duration or intensity of painful stimuli that one is able to bear. This review will focus on integrating current clinical and neurobiological findings by which psychache and pain tolerance confer suicide risk.

RECENT FINDINGS

Results indicate that psychache has been identified as a significant risk factor for suicide and that psychache may be associated with the neurocircuitry involved in the modulation of physical pain. Converging evidence has also been found linking pain tolerance to self-injurious behaviours and suicide risk. The experience of psychache and physical pain in relation to other predictors of suicide, including reward processing, hopelessness and depression, are further discussed.

SUMMARY

Future research examining the pain-suicide connection is required to understand the mechanism behind clinically relevant risk factors for suicide, which can ultimately inform the construction of empirically supported suicide risk assessment and intervention techniques.

Death ideation in older adults: psychological symptoms of depression, thwarted belongingness, and perceived burdensomeness

Death ideation is commonly reported by older adults in the United States; however, the factors contributing to death ideation in older adults are not fully understood. Depressive symptoms, as well as components of the interpersonal theory of suicide, perceived burden, and thwarted belonging may contribute to death ideation.

OBJECTIVES

The purpose of this study was to investigate the moderating relationship of the psychological symptoms of depression on the relation between perceived burdensomeness and death ideation, and thwarted belongingness and death ideation.

METHOD

A sample of 151 older adults completed questionnaires assessing numerous covariates, as well as perceived burdensomeness, thwarted belongingness, death ideation, and the psychological symptoms of depression.

RESULTS

The results of this study indicated that the proposed moderating relationship was supported for the relationship between perceived burdensomeness and death ideation, but was not supported for the relationship between thwarted belongingness and death ideation when covariates (loneliness and hopelessness) were controlled.

CONCLUSION

This suggests that the psychological symptoms of depression are significantly associated with death ideation in older adults experiencing feelings of perceived burdensomeness. Additionally, the findings suggest that loneliness and hopelessness are also important factors to consider when assessing death ideation in older adults.

Ketamine for Treatment of Suicidal Ideation and Reduction of Risk for Suicidal Behavior

Ketamine, an NMDA receptor antagonist with efficacy as a rapid anti-depressant, has early evidence for action to reduce suicidal ideation. This review will explore several important questions that arise from these studies. First, how do we measure reductions in suicidal ideation that occur over minutes to hours? Second, are the reductions in suicidal ideation after ketamine treatment solely a result of its rapid anti-depressant effect? Third, is ketamine only effective in reducing suicidal ideation in patients with mood disorders? Fourth, could ketamine's action lead us to a greater understanding of the neurobiology of suicidal processes? Last, do the reductions in depression and suicidal ideation after ketamine treatment translate into decreased risk for suicidal behavior? Our review concludes that ketamine treatment can be seen as a double-edged sword, clinically to help provide treatment for acutely suicidal patients and experimentally to explore the neurobiological nature of suicidal ideation and suicidal behavior.

A systematic review of the predictions of the Interpersonal-Psychological Theory of Suicidal Behavior

CONTEXT

Since the development of the Interpersonal Psychological Theory (IPTS; Joiner, 2005), a growing body of literature has emerged testing different aspects of the theory across a range of populations.

OBJECTIVE

The aim of this review was to identify support for the IPTS, and critical gaps in the evidence base, by systematically reviewing current evidence testing the effects of thwarted belongingness, perceived burdensomeness, and acquired capability on suicide ideation and attempt.

METHODS

PsycInfo and PubMed databases were electronically searched for articles published between January 2005 and July 2015. Articles were included if they directly assessed the IPTS constructs as predictors of suicidal ideation or suicide attempt.

RESULTS

Fifty-eight articles reporting on 66 studies were identified. Contrary to expectations, the studies provided mixed evidence across the theory's main predictions. The effect of perceived burdensomeness on suicide ideation was the most tested and supported relationship. The theory's other predictions, particularly in terms of critical interaction effects, were less strongly supported.

CONCLUSIONS

Future research focused on expanding the availability of valid measurement approaches for the interpersonal risk factors, and further elaborating upon their mixed relationships with suicide ideation and attempt across multiple populations is important to advance theoretical and clinical progress in the field.

The Perception of Being a Burden in Acute and Chronic Pain Patients Is Associated with Affirmation of Different Types of Suicidality

OBJECTIVES

The perception of being a burden or self-perceived burden (SPB) is associated with suicide ideation in chronic pain patients (CPPs). The objective of this study was to determine if SPB is associated with five types of suicidality (wish to die, active suicide ideation, presence of suicide plan, history of suicide attempts, and preference for death over being disabled) in CPPs and acute pain patients (APPs).

METHODS

Affirmation of SPB was statistically compared between community nonpatients without pain (CNPWP), APPs, and CPPs. APPs and CPPs who had affirmed any of the five types of suicidality were compared statistically for affirmation of SPB. Hierarchical regression analysis was utilized to determine the significance of SPB in predicting each of the five types of suicidality in APPs and CPPs controlling for age, gender, race, education status, and two types of measures of depression (current depression and vegetative depression).

RESULTS

APPs and CPPs were statistically more likely to affirm SPB than CNPWPs and CPPs were more likely than APPs to do so. There were no differences between APPs and CPPs in affirming SPB in APPs and CPPs who had affirmed any of the five types of suicidality. In CPPs, SPB predicted each type of suicidality in a significant fashion utilizing both types of depression measures. For APPs, SPB predicted each type of suicidality in a significant fashion except for history of suicide attempt controlling for vegetative depression.

CONCLUSIONS

SPB is associated with the vast majority of different types of suicidality in APPs and CPPs.

Too Much to Bear: Psychometric Evidence Supporting the Perceived Burdensomeness Scale

BACKGROUND

People who feel they have become a burden on others may become susceptible to suicidal ideation. When people no longer feel capable or productive, they may assume that friends and family members would be better off without them.

AIM

The present study was designed to assess preliminary psychometric properties of a new measure, the Perceived Burdensomeness (PBS) Scale.

METHOD

Depressed psychiatric patients (N = 173) were recruited from a veterans affairs medical center. Patients were assessed with a structured diagnostic interview and self-report measures assessing perceived burdensomeness, depression severity, hopelessness, and suicidal ideation.

RESULTS

The present study supported preliminary evidence of reliability and concurrent validity of the PBS. Additionally, perceived burdensomeness was significantly associated with higher levels of hopelessness and suicidal ideation.

CONCLUSION

It is hoped that with the aid of the PBS clinicians may be able to intervene more specifically in the treatment of suicidality.

The risk of suicide mortality in chronic pain patients

Chronic pain has long been considered an important risk factor for suicidal behavior. Less well understood are the factors associated with the increased risk for suicide death within chronic pain populations. The purpose of this review is to examine recent research with regard to rates of and risk factors for suicide mortality in patients with chronic musculoskeletal pain. We conclude that patients with a number of chronic pain states are at increased risk for suicide death, and that this risk appears to be due, at least in part, to other well-known correlates of pain such as depression and substance use disorders. However, in all likelihood, there are aspects of chronic pain itself that add uniquely to an individual's suicide risk profile. Lastly, we address a theoretical perspective and offer recommendations for clinical practice.

Interactions between injured workers and insurers in workers' compensation systems: a systematic review of qualitative research literature

INTRODUCTION

Work-related injury is a major public health problem and a worker's recovery can be shaped by their interactions with employers, healthcare providers and the workers' compensation system. Most research on the effects of compensation has concentrated on examining outcomes rather than considering the compensation process itself. There has been little attention paid to the interactions between stakeholders and only recently has the client's view been considered as worthy of investigation. This systematic review aimed to identify and synthesize findings from peer reviewed qualitative studies that investigated injured workers interactions with insurers in workers' compensation systems.

METHOD

A search of six electronic library databases revealed 1,006 articles. After screening for relevance, 18 articles were read in full and a search of those bibliographies revealed a further nine relevant articles. Quality assessment of the 27 studies resulted in a final 13 articles of medium and high quality being retained for data extraction.

RESULTS

Included studies focused mainly on experiences of injured workers, many of whom had long term claims. Findings were synthesized using a meta-ethnographic approach. Six themes were identified which characterised the interactions between insurers and injured workers. The majority of interactions were negative and resulted in considerable psychosocial consequences for injured workers. Positive interactions were less frequently reported and included respectful, understanding and supportive communication and efficient service from insurers.

CONCLUSION

Findings from this synthesis support the growing consensus that involvement in compensation systems contributes to poorer outcomes for claimants. Interactions between insurers and injured workers were interwoven in cyclical and pathogenic relationships, which influence the development of secondary injury in the form of psychosocial consequences instead of fostering recovery of injured workers. This review suggests that further research is required to investigate positive interactions and identify mechanisms to better support and prevent secondary psychosocial harm to injured workers.

Attachment insecurity predicts responses to an interdisciplinary chronic pain rehabilitation program

The aim of this study was to examine the hypothesis that attachment insecurity is associated with poorer responses to interdisciplinary treatment for chronic pain. Patients (n = 235) admitted to a 4-week interdisciplinary rehabilitation program were recruited. At pre-treatment, participants completed a battery of questionnaires assessing adult attachment styles and dimensions, as well as pain intensity, disability, self-efficacy, pain catastrophizing, and depressive symptoms. The latter measures were completed again at post-treatment. Nearly two-thirds of participants (65.5 %) reported having an insecure attachment style. Attachment insecurity was unrelated to pre- and post-treatment reports of pain intensity and pain-related disability, but was significantly associated with most other clinical variables at both time points. Regression analyses controlling for pre-treatment functioning indicated that attachment insecurity was associated with less improvement in pain catastrophizing, pain self-efficacy, and depressive symptoms. Further research is warranted to investigate the processes by which attachment characteristics influence patients' responses to chronic pain rehabilitation.

Values as Moderators of the Association between Interpersonal-Psychological Constructs and Suicidal Ideation among Veterans

This study examined whether valuing relationships, achievement, and security moderated the association between interpersonal-psychological constructs (Joiner, 2005) and suicidal ideation (SI). A total of 122 veterans completed the Interpersonal Needs Questionnaire, Survey of Life Principles, and Beck Scale for Suicide Ideation. Valuing relationships moderated the association between thwarted belongingness and SI. Specifically, thwarted belongingness predicted SI among veterans who reported moderate and high, but not low, levels of valuing relationships. The estimated impact of perceived burdensomeness on SI was stronger at higher levels of valuing relationships, but only approached statistical significance. Valuing achievement and security did not moderate the association between perceived burdensomeness and SI. Future research should continue to examine specific values as they relate to interpersonal-psychological constructs and suicidal behavior.

Change in suicidal ideation after interdisciplinary treatment of chronic pain

OBJECTIVES

To examine suicidal ideation (SI) in individuals with chronic pain, especially change in suicidal thinking after interdisciplinary treatment.

MATERIALS AND METHODS

Consecutive patients (n=250) admitted to a 4-week, group-based chronic pain management program completed measures of pain intensity, functional limitations, depressive symptoms, overall distress, pain catastrophizing, self-perceived burden, and SI at pretreatment and posttreatment.

RESULTS

Before treatment, 30 (12.0%) participants were classified as having a high level of SI, 56 (22.4%) had a low level of SI, and 164 (65.6%) reported none. After treatment, there was a significant reduction in SI and improvements in all other outcomes, but there were still some individuals with high (n=22, 8.8%) or low (n=28, 11.2%) levels at discharge. Patients with high SI at baseline differed from those with no suicidal thinking on pretreatment and posttreatment measures of depression, distress, catastrophizing, and self-perceived burden, but not on pain intensity or functional limitations. Patients high in SI endorsed greater pain catastrophizing and self-perceived burden than those low in suicidal thinking. Sustained SI after treatment was associated with higher baseline levels of suicidal thinking and self-perceived burden to others, as well as a more limited overall response to treatment.

DISCUSSION

SI was common in individuals with chronic pain, although mostly at a low level. Interdisciplinary treatment may result in reduced suicidal thinking; however, some patients continue to express thoughts of self-harm. Future studies could examine processes of change and interventions for treatment-resistant suicidal concerns.
