Tolerance for psychological pain and capability for suicide: Contributions to suicidal ideation and behavior

Fearlessness about death and suicidal ideation: Religious identity matters

INTRODUCTION

Religion is a salient aspect of patient background in treatment (The psychology of religion and coping: Theory, research, practice; Guilford Press). However, research investigating the role of religion in suicide is lacking and inconsistent (Journal of Religion and Health, 57, 2478-2499). The current study (1) clarifies the association between religious identity and fearlessness about death in a psychiatric sample and (2) tests whether religious identity moderates the association between fearlessness about death and suicidal ideation.

METHODS

Participants were 155 patients seeking treatment in a partial hospital program. Religious identity was assessed using the Identities in Treatment Scale (The Behavior Therapist). Fearlessness about death was assessed with two relevant items from the acquired capability with rehearsal for suicide scale (Psychological Assessment, 28, 1452-1464), as in prior studies (Suicide & Le-Threatening Behavior, 50, 1230-1240; Journal of Affective Disorders Reports, 12, 100492).

RESULTS

Fearlessness about death interacted with religious identity to predict suicidal ideation, b = 0.47, 95% C.I. [0.02, 0.91], p = 0.042. Conditional effects showed that greater fearlessness about death was associated with greater suicidal ideation among non-religious patients, b = -0.56, 95% C.I. [-0.88, -0.24], p = 0.001, but not in religious patients, b = -0.09, 95% C.I. [-0.41, 0.22], p = 0.559.

CONCLUSIONS

Our results suggest that fearlessness about death is a risk factor for suicidal ideation, but only among those who do not identify as religious. Results from this study inform theories of suicide and elucidate the influence of religious identity on links among suicide risk factors and suicide-related outcomes.

Decreased beta 1 (12-15 Hertz) power modulates the transfer of suicidal ideation to suicide in major depressive disorder

BACKGROUND

Suicide prevention for major depressive disorder (MDD) is a worldwide challenge, especially for suicide attempt (SA). Viewing suicide as a state rather than a lifetime event provided new perspectives on suicide research.

OBJECTIVE

This study aimed to verify and complement SAs biomarkers of MDD with a recent SA sample.

METHODS

This study included 189 participants (60 healthy controls; 47 MDD patients with non-suicide (MDD-NSs), 40 MDD patients with suicide ideation (MDD-SIs) and 42 MDD patients with SA (MDD-SAs)). MDD patients with an acute SA time was determined to be within 1 week since the last SA. SUICIDALITY Part in MINI was applied to evaluate suicidality. Absolute powers in 14 frequency bands were extracted from subject's resting-state electroencephalography data and compared within four groups. The relationship among suicidality, the number of SA and powers in significant frequency bands were investigated.

RESULTS

MDD-SIs had increased powers in delta, theta, alpha and beta band on the right frontocentral channels compared to MDD-NSs, while MDD-SAs had decreased powers in delta, beta and gamma bands on widely the right frontocentral and parietooccipital channels compared to MDD-SIs. Beta 1 power was the lowest in MDD-SAs and was modulated by the number of SA. The correlation between suicidality and beta 1 power was negative in MDD-SAs and positive in MDD-SIs.

CONCLUSION

Reduced beta 1 (12-15 Hz) power could be essential in promoting suicidal behaviour in MDD. Research on recent SA samples contributes to a better understanding of suicide mechanisms and preventing suicidal behaviour in MDD.

Associations Between the Suicidal Ideation and the Tolerance for Psychological Pain and Tolerance for Physical Pain in Patients Diagnosed with Major Depressive Disorder

Purpose

Patients with major depressive disorder (MDD) may experience more frequent and severe psychological and physical pain complaints compared to those without depression. As the tolerance to psychological pain decreases in patients with MDD, the severity of suicidal ideation tends to increase. Furthermore, the tolerance for physical pain (TPP) has been related with suicidal behavior. We aimed to demonstrate the impact of TPP on suicidal ideation in patients with MDD in the presence of psychological pain.

Patients and Methods

We included 123 patients with MDD and 114 healthy volunteers who had no previous psychiatric diagnosis. Sociodemographic data form, Psychache Scale (PS) and Tolerance for Mental Pain Scale (TMPS) were used to assess psychological pain. Beck Scale for Suicide Ideation (BSIS) and Beck Depression Inventory (BDI) were administered to participants. To assess the TPP, we used a device based on the principle of electronic dynamometry.

Results

The mean BDI, BSIS, PS, and TPP scores in the MDD group were higher, and the mean TMPS score was lower than those in the control group (p < 0.001 for each, p = 0.03 for TPP). We found statistically significant correlations between BDI, TMPS, BSIS, PS, and TPP scores (p < 0.05 for each). TPP was a partial mediator in the relationship between TMPS and BSIS scores (β = -1.814; p < 0.001).

Conclusion

We found that tolerance of psychological pain was a strong predictor of suicidal ideation, and TPP was mediating this relationship. These findings suggest that considering both tolerance to psychological pain and TPP may be beneficial when assessing the risk of suicide in individuals with MDD.

The relationship of coping skills with psychache in patients with depressive disorder

Suicide is a leading cause of death and disability worldwide. Psychache (psychological pain) and diminished tolerance of psychaches are important risk factors for suicide. People experiencing psychaches of similar severity may not demonstrate the same levels of tolerance because of various coping skills. This study aimed to determine the relationship between psychache, tolerance for psychache, and coping skills in individuals with depression and healthy controls. We included 73 patients with depressive disorders without comorbid mental disorders and 65 healthy controls. We applied beck depression inventory, beck hopelessness scale, beck suicidal ideation scale, psychache scale, tolerance for mental pain scale (TMPS), and coping attitudes evaluation scale (COPE) to all participants. People with depression had significantly higher COPE dysfunction scores than those in the control group did. Patients who had previously attempted suicide attempt(s) previously had significantly higher beck hopelessness scale, beck depression inventory, COPE dysfunction, and psychache scale scores, and lower TMPS-10 scores than those who did not attempt suicide. Mediation analyses revealed that dysfunctional coping skills played a partial mediating role in the relationship between psychache and the TMPS. The study revealed that dysfunctional coping skills were related to suicidal ideation and previous suicide attempts. These findings suggest that improving coping skills could help reduce the severity of suicidal ideation.

The Mediating Role of Tolerance for Psychological Pain in the Relationship Between Different Types of Childhood Traumatic Experiences and Suicidal Ideation

The aim of the present research was to evaluate the mediating effects of facets of the tolerance for psychological pain on the relationship between childhood trauma and suicidal ideation. A sample of 437 community individuals and a sample of 316 college students participated. For the community sample, managing the pain mediated the relationship between childhood trauma, the different types of traumatic experiences and suicidal ideation. In the college sample, managing the pain and enduring the pain mediated the relationship between childhood trauma, the different types of traumatic experiences and suicidal ideation, except for the case of sexual abuse. The present results have potential clinical implications. Mental health professionals should be aware of the long-term consequences of exposure to childhood trauma and need to assess the ability to tolerate psychological pain so as to implement appropriate psychological interventions that help individuals cope with their pain.

Racial Differences in the Relationship Between Pain and Suicide Desire in Older Adults

Older adults are reported to die by suicide at higher rates than the general population. Suicide desire among older adults is associated with pain, and pain experiences have been found to differ based on race. To investigate the relationship between pain and suicidal desire, 437 racially diverse older adults who receive home-based services (home-delivered meals) in the Southeastern region of the United States completed standardized measures of psychological pain, chronic physical pain, and suicidal desire. Results identified race moderated the relationship between pain and suicidal desire, indicating a stronger relationship between pain and suicidal desire among Black older adults than White older adults. Chronic physical pain (i.e., emotional burden) interacted with race to predict Perceived Burdensomeness ( p = .011) and Thwarted Belongingness ( p = .032). Greater attention to pain experiences among Black older adults is warranted, considering the impact of COVID-19 on racial/ethnic minorities’ mental health.

The relevance of the interpersonal theory of suicide for predicting past-year and lifetime suicidality in autistic adults

Background

While there are known risk factors for suicidality in autistic adults, these are often unconnected from theoretical frameworks that might explain why risk is elevated and guide clinical interventions. The present study investigated the relevance of constructs from the Interpersonal Theory of Suicide (ITS), including perceived burdensomeness, thwarted belongingness and acquired capability for suicide, and explored mechanisms through which certain risk factors (relationship status, age at diagnosis) might elevate suicide risk.

Methods

Autistic adults (n = 314) completed an online study including measures of depression, anxiety and constructs from the ITS. Linear and multinomial regression analysis disentangled contributions of ITS variables from effects of depression and anxiety for past-year suicide ideation, past-year and lifetime suicide attempts. Mediation analyses examined associations between risk factors and these suicide outcomes via mechanisms proposed by the ITS.

Results

Past-year suicide ideation was associated with burdensomeness, mental rehearsal of suicide plans (a facet of acquired capability), and depression. Greater feelings of burdensomeness, and reduced fear of death, marked out participants who had attempted suicide in comparison to those who had experienced suicide ideation in the past year. Relationship status was indirectly associated with past-year suicide ideation via the mediators of depression and burdensomeness, and was associated with past-year attempts via its effect on ideation. Age at diagnosis was unrelated to any variables.

Limitations

Cross-sectional research is insensitive to causality and temporal dynamics, which is likely why interaction hypotheses from the ITS were unsupported. Normative measures may be invalid in autistic samples. There was no control group. The autistic sample was unrepresentative of the whole population, particularly autistic people with intellectual disabilities, ethnic/racial minorities, and gender minorities.

Conclusions

Perceived burdensomeness and acquired capability appear potentially important to suicide in autistic people, and may mediate the effects of some risk factors. Future research should explore the temporal dynamics of suicide trajectories in longitudinal, prospective designs.

Mental Pain, Psychological Distress, and Suicidal Ideation During the COVID-19 Emergency: the Moderating Role of Tolerance for Mental Pain

The psychosocial stressors related to the ongoing COVID-19 pandemic and associated lockdowns have been shown to lead to an exacerbation of suicide risk. The present study aims to examine (a) the contribution of mental pain intensity to psychological distress and suicidal ideation during the COVID-19 pandemic and (b) the protective role of mental pain tolerance in buffering these adverse mental health effects. A total of 652 adults (74.2% female, M = 33.99 years, SD = 13.74) were assessed through an online survey during the first mandatory lockdown in Italy. Participants completed measures of mental pain intensity and tolerance, psychological distress, and suicidal ideation. Results showed that mental pain intensity significantly predicted increases in psychological distress and suicidal ideation while mental pain tolerance significantly buffered the adverse effects of mental pain intensity on psychological distress and suicidal ideation. The findings highlight that tolerance for mental pain may act as a powerful protective factor during the pandemic. Evidence-based public health interventions fostering tolerance for mental pain during a pandemic are needed in order to effectively reduce suicide in potential risk groups.

The mediating role of tolerance for psychological pain in the relationship of childhood trauma to suicidal ideation in individuals with a substance use disorder

OBJECTIVES

The association between childhood trauma and suicidal ideation has been well documented in several populations, including individuals with a substance use disorder (SUD). However, a gap still exists in the literature regarding the mechanisms by which childhood trauma later impacts suicide risk. This cross-sectional study tested the effect of childhood trauma on suicidal ideation, as well as the mediating effect of tolerance for psychological pain (managing the pain and enduring the pain) in that relationship, controlling for the effect of depressive symptoms, in individuals with a SUD.

METHODS

A sample of 102 adults with a SUD participated in the study. Path analysis by structural equation␣modelling tested a mediation model.

RESULTS

Depressive symptoms and lower levels of managing the pain were found to fully mediate the association between childhood trauma and suicidal ideation.

CONCLUSIONS

Our results suggest that depressive symptoms and a lack of ability to manage psychological pain contribute towards explaining why traumatic childhood experiences may result in suicidal cognitions in individuals with SUDs. Moreover, they have relevant implications for prevention and clinical interventions regarding suicidal ideation in this population.

PRACTITIONER POINTS

Childhood trauma relates to suicidal ideation in individuals with a substance use disorder. Depressive symptoms contribute towards explaining why traumatic childhood experiences may result in suicidal cognitions. A lack of ability to manage psychological pain also contributes towards explaining this relationship. The obtained results have relevant implications for the prevention of and clinical intervention for suicidal ideation in SUD individuals.

Mechanisms Underlying the Anti-Suicidal Treatment Potential of Buprenorphine

Death by suicide is a global epidemic with over 800 K suicidal deaths worlwide in 2012. Suicide is the 10th leading cause of death among Americans and more than 44 K people died by suicide in 2019 in the United States. Patients with chronic pain, including, but not limited to, those with substance use disorders, are particularly vulnerable. Chronic pain patients have twice the risk of death by suicide compared to those without pain, and 50% of chronic pain patients report that they have considered suicide at some point due to their pain. The kappa opioid system is implicated in negative mood states including dysphoria, depression, and anxiety, and recent evidence shows that chronic pain increases the function of this system in limbic brain regions important for affect and motivation. Additionally, dynorphin, the endogenous ligand that activates the kappa opioid receptor is increased in the caudate putamen of human suicide victims. A potential treatment for reducing suicidal ideation and suicidal attempts is buprenorphine. Buprenorphine, a partial mu opioid agonist with kappa opioid antagonist properties, reduced suicidal ideation in chronic pain patients with and without an opioid use disorder. This review will highlight the clinical and preclinical evidence to support the use of buprenorphine in mitigating pain-induced negative affective states and suicidal thoughts, where these effects are at least partially mediated via its kappa antagonist properties.

Psychological pain: A moderating factor between personality psychopathology and self-harm

Self-harm and personality psychopathology have been linked, with the most robust correlations existing between negative affectivity and self-harm. Psychological pain, an emotionally-based aversive feeling, has been linked to self-harm. Considering the connection between personality psychopathology and self-harm, psychological pain may enhance self-harm risk. Participants: Analyses were conducted on 525 undergraduate students in the Spring and Fall semesters of 2019. Methods/Results: Correlation analyses indicated that self-harm was moderately correlated with Negative Affectivity, Detachment, Antagonism, Disinhibition, and Psychoticism. Additionally, self-harm was correlated with psychological pain. When examining if psychological pain moderates the relation between personality psychopathology and self-harm, results were mixed. In the cases of Disinhibition and Psychoticism, psychological pain enhanced self-harm. There was no moderating effect on the relations with Negative Affectivity, Detachment, or Antagonism. Conclusions: These findings support the role of psychological pain in self-harm outcomes for those experiencing personality psychopathology; however, this varies depending on the maladaptive traits.

Thoughts of Death, Depression and Guilt in a Healthcare Worker Who Infected Her Husband with SARS-CoV-2: A Case Report

BACKGROUND

The worldwide spread of the novel coronavirus (SARS-CoV-2) has exposed healthcare workers (HCWs) to physical and mental disorders both directly and indirectly related to the pandemic. Italy was the first European country affected by the SARS-CoV-2 pandemic, and Italian HCWs have presented adverse psychological outcomes related to work and emotional overload and the fears of becoming infected and infecting others, particularly loved ones.

CASE PRESENTATION

We report the case of a 61-year-old HCW who likely infected her husband with SARS-CoV-2, leading to his death. We assessed the depressive and anxious symptoms that the patient experienced after the death of her husband, which were characterized by a deep sense of guilt, psychological pain, and thoughts of death.

CONCLUSION

In our opinion, our case emphasizes the fact that HCWs need greater mental health assistance, particularly those who are heavily involved in the care of patients and who have possible risk factors for psychiatric symptoms.

Exploring the scope and structure of suicide capability

OBJECTIVE

Recent theories of suicide suggest that a construct called "capability for suicide" facilitates the progression from suicidal thoughts to attempts. Various measures of capability have been developed to assess different parts of the construct, but studies report inconsistent findings regarding reliability, validity, and structure. The present study pooled items from multiple measures to identify distinct, reliable, and valid domains of suicide capability.

METHOD

We administered items from several suicide capability measures to an online sample of US adults (n = 387), and utilized exploratory factor analysis to identify distinct domains of capability. We then examined the internal consistencies of and intercorrelations among these domains, as well as their associations with suicide attempts.

RESULTS

Findings identified three domains of suicide capability: fearlessness about death, practical capability, and pain tolerance. These domains were internally consistent (αs = 0.80-0.92), and relatively independent from one another (intercorrelations = 0.15-0.35). Finally, each of these domains was moderately elevated among attempters compared to ideators (although only fearlessness about death and practical capability offered unique information about attempter status).

CONCLUSIONS

Findings suggest that fearlessness about death, practical capability, and pain tolerance can be measured reliably, and may be relevant for understanding which ideators make attempts.

Tolerance for Mental Pain Scale (TMPS): Italian validation and evaluation of its protective role in depression and suicidal ideation

Mental pain and tolerance for mental pain have been receiving international recognition as transdiagnostic constructs related to many psychiatric conditions as well as increased probability of suicide. The purpose of this study was to adapt and validate the Tolerance for Mental Pain Scale (TMPS) in Italian and to examine its protective role in depression and suicidal ideation. To this aim, psychometric proprieties of the instrument were explored as well as their association with depression and suicidal ideation on an Italian adult community sample (N = 204). Participants filled out the TMPS together with scales tapping intensity of mental pain, depression and other clinically relevant variables. Compared to the original version, the TMPS-10 demonstrated better psychometric properties and was validated in Italian. The two-factor structure of the Italian TMPS-10 (Managing the Pain, Enduring the Pain) was replicated. The instrument showed adequate construct validity and gender measurement invariance. Furthermore, regression analyses evinced a significant protective role of tolerance for mental pain in depressive symptomatology and suicidal ideation. The Italian TMPS-10 is a valid and reliable measure to assess tolerance for mental pain and seems to be a promising instrument to identify those at risk for depressive psychopathology and suicide.

Psychological pain and risk of suicide in adolescence

Psychological pain or psychache is intolerable and unacceptable mental pain. This construct plays a key role in the risk of suicide in adolescence. This is a frequent condition in adolescents with depression; a variety of studies propose a bidirectional relationship between these two circumstances. Adolescents with psychological pain are exposed to the risk of suicidal ideation, and behavior. This review aimed to explore psychological pain in adolescents, and the correlation to the risk of suicide. We have conducted, following PRISMA guidelines, a systematic review for the literature on PubMed. Search terms were "Suicide risk in adolescents" AND "Mental Pain in adolescence" OR "Psychological Pain in adolescence". An initial search identified publications 1189. A total of 15 studies met the predefined inclusion criteria and were analyzed. Mental pain is a stronger factor of vulnerability of suicidal ideation and behavior. Intense negative emotions, such as guilt, shame, hopelessness, may become a psychological pain in adolescence, and many studies showed a relation between psychological pain and capability for suicide.

Characterizing the phenomenology of passive suicidal ideation: a systematic review and meta-analysis of its prevalence, psychiatric comorbidity, correlates, and comparisons with active suicidal ideation

BACKGROUND

Compared to active ideation, passive ideation remains relatively understudied and its clinical importance poorly defined. The weight that should be accorded passive ideation in clinical risk assessment is therefore unclear.

METHODS

We conducted a systematic review and meta-analysis of the prevalence of passive ideation, its psychiatric comorbidity, associated sociodemographic characteristics, as well as psychological and environmental correlates. For reference, pooled effects were also calculated for direct comparisons of passive and active ideation with respect to potential correlates. Relevant articles published since inception to 9 September 2019 were identified through a systematic search of MEDLINE and PsycINFO.

RESULTS

A total of 86 studies were included in this review. The prevalence of passive ideation was high across sample types, ranging from 5.8% for 1-year prevalence to 10.6% for lifetime prevalence in the general population. Passive ideation was strongly associated with sexual minority status, psychiatric comorbidity, psychological characteristics implicated in risk, and suicide attempts. Preliminary evidence exists for a large association with suicide deaths. The effect sizes for individual correlates of passive and active ideation were largely equivalent and mostly non-significant in head-to-head comparisons.

CONCLUSIONS

Passive ideation is a prevalent clinical phenomenon associated with significant psychiatric comorbidity. Current evidence also suggests notable similarities exist between passive and active ideation in terms of psychiatric comorbidity and psychological and other characteristics traditionally associated with risk.

From depressive symptoms to suicide risk: Roles of sense of belongingness and acquired capability for suicide in patients with mental disorders

In order to prevent suicides in patients with mental disorders, it was critical to recognize the risk factors and explore the mechanism. Based on depressive symptoms, which were common in patients with mental disorders in consolidation period in China, we constructed a moderated mediating model under the framework of Integrated Motivational-Volitional Model of suicidal behaviour, and examined the mechanism of how depressive symptoms, thwarted belongingness, and acquired capability for suicide influenced suicide risk. In this study, data were collected from 164 patients through four questionnaires, and analyzed with PROCESS macro for SPSS (Hayes, 2008). The result showed that in the predictive effects of depressive symptoms on suicide risk, thwarted belongingness was a partial mediating variable, while acquired capability for suicide played a moderating role in the partial mediating model. Specifically, the predictive effects of depressive symptoms and thwarted belongingness, both as motivation variables, on suicide risk both occurred in the case of the high acquired capability of suicide, which was a volition variable. The research pointed out the interdependence of depressive symptoms and a sense of belongingness, and clarified the critical role of acquired capability for suicide. The integrated perspective could enhance the interpretation of reality, and enlightened those carrying out the practice of suicide intervention to patients with mental disorders.

The Role of Opiates in Social Pain and Suicidal Behavior

With more than 800,000 deaths by suicide each year and 20 to 30 times more suicide attempts worldwide, suicide is a major public health problem. Current treatments of SB are mainly based on pharmacological treatments that are not specific of SB (e.g. antidepressants), and new therapeutic targets are urgently needed. Recent data strengthen the ancient conception pain (social, psychic, physical) that is at the core of the suicidal process and should be incorporated in the clinical assessment of suicide risk. Then, the mechanisms involved in the regulation of pain may open new avenues regarding therapeutic perspectives. Opiates appear to be a promising candidate in treatment of SB. Indeed, since the last two decades, growing evidences suggest an implication of the opioid system in the pathophysiology of SB, this conduct to the elaboration of randomized controlled trials (RCTs) using opiates in patients with SB. Results suggesting an anti-suicidal effect of buprenorphine and the potential opioidergic-related anti-suicidal effect of ketamine both contribute to the growing interest in opiates use in SB. In this review, we will summarize a large part of the evidence that leads researchers and clinicians to be interested in the use of opiates for SB treatment and discuss on new opioid pharmacological options for suicidal patients.

Biological bases of suicidal behaviours: A narrative review

Suicidal behaviour is a multifaceted phenomenon that concerns all human populations. It has been suggested that a complex interaction between the individual genetic profile and environmental factors throughout life underlies the pathophysiology of suicidal behaviour. Although epidemiological and genetic studies suggest the existence of a genetic component, exposure to biological and psychosocial adversities, especially during critical developmental periods, also contributes to altering the biological responses to threat and pleasure. This results in amplified maladaptive cognitive and behavioural traits and states associated with suicidal behaviours. Alterations in the cognitive inhibition and decision-making capacity have been implicated in suicidal behaviours. Structural and functional changes in key brain regions and networks, such as prefrontal cortex, insula and default mode network, may underlie this relationship. Furthermore, the shift from health to suicidal behaviour incorporates complex and dynamic changes in the immune and stress responses, monoaminergic system, gonadal system and neuroplasticity. In this review, we describe the major findings of epidemiological, genetic, neuroanatomical, neuropsychological, immunological and neuroendocrinological studies on suicide behaviours to provide a solid background for future research in this field. This broad overview of the biological bases of suicide should promote neuroscience research on suicidal behaviours. This might lead to improved biological models and to the identification of evidence-based biomarkers, treatment options and preventive strategies.

Predicting status along the continuum of suicidal thoughts and behavior among those with a history of nonsuicidal self-injury

Nonsuicidal self-injury (NSSI) and suicidal thoughts and behavior often co-occur, representing a growing public health concern. Despite extensive research examining suicidal thoughts and behavior among those who engage in NSSI, there is a lack of research investigating factors that, when considered together, can differentiate individuals along the continuum of suicidal thoughts and behavior (no history, suicidal ideation, suicide plan, suicide attempt). This study sought to address this question using a sample of 1178 college students with NSSI history (68.70% female). Discriminant function analysis was conducted including the following predictors: NSSI characteristics, negative affect difficulties, and behavioral and demographic risk factors for suicidal thoughts and behavior. Results suggest that self-disclosure of suicidal ideation, number of lifetime NSSI methods, NSSI frequency, depressive symptoms, and age most parsimoniously differentiate study groups. Those who use a greater number of NSSI methods and acts, paired with higher depressive symptoms and repeated self-disclosure of suicidal ideation are most likely to have a suicide attempt history; decreases in these variables suggest membership within less severe groups. Furthermore, older age may be related to greater suicidality. Findings suggest that the evaluation and co-occurrence of these variables may contribute to a more accurate suicide risk assessment.

Psychometric evaluation of the Tolerance for Mental Pain Scale in United States adults

The purpose of the present study was to analyze the factor structure of the Tolerance for Mental Pain Scale (TMPS) in a sample of United States adults and examine its associations with suicidal behavior and intensity of psychological pain. Data were collected through an online general population survey (N = 225), and statistical analysis consisted of factor analysis and descriptive statistics of the data. Confirmatory factor analysis did not indicate a good fit with the originally proposed three-factor model. Subsequent exploratory factor analysis showed a good fit for a two-factor solution while enabling reduction of the scale to ten items, which we refer to as TMPS-10. The TMPS-10 scores were significantly lower for respondents with a lifetime history of attempted suicide and significantly inversely associated with the intensity of psychological pain. We recommend using the TMPS-10 to assess tolerance for mental pain for research purposes. With half the number of items of the original scale, the TMPS-10 has a lower response burden and minimizes the risk of over-inflating internal consistency due to redundant items.
