RESUMO

OBJECTIVES: Discrepancies persist regarding the extent to which different pain measures provide similar information and relate to capability for suicide and self-injurious behaviors. This study examined pain threshold, tolerance, and persistence across four modalities (cold, heat, pressure, shock) and assessed associations with self-reported capability for suicide, non-suicidal self-injury (NSSI), and suicide attempts. METHODS: A sample of 211 students who reported lifetime suicidal ideation completed four behavioral pain tasks and self-reported on capability for suicide, NSSI, and self-injurious behaviors. RESULTS: All pain thresholds, tolerances, and persistences were positively correlated across the four tasks. Pain facets were related to self-reported capability for suicide with small effect sizes but generally did not differ across suicide attempt or NSSI histories. CONCLUSIONS: Pain thresholds, tolerances, and persistences demonstrated convergent validity across the four modalities, suggesting that these tasks provide similar information. Although the relation between pain and self-injurious behaviors remains unclear, these tasks can generally be used interchangeably.

RESUMO

BACKGROUND: The German Capability for Suicide Questionnaire (GCSQ) was developed to measure fearlessness of death and pain tolerance - two constructs central to the Interpersonal Theory of Suicide. Initial scale development, definition of the factor structure and confirmation of the two-dimensional factor structure was performed in samples suffering from relatively low levels of suicide ideation/behavior. The present study aimed to validate the German Capability for Suicide Questionnaire (GCSQ) in a high-risk sample of suicidal inpatients. METHODS: Factor structure, reliability and validity were investigated in a sample of inpatients (N = 296; 53.0% female; age in years: M = 36.81, SD = 14.27) admitted to a hospital due to a recent suicide attempt or an acute suicidal crisis (in immediate need of inpatient treatment). To establish convergent validity, interview-based assessments of lifetime suicide attempts and non-suicidal self-injury as well as questionnaire-based assessments of painful and provocative events were used. Finally, stability of GCSQ-scores over a follow-up period of 12 months was assessed. RESULTS: Results indicated good psychometric properties, and provided additional evidence for construct validity and stability of the subscales over a one-year period, and demonstrated adequate fit of the data with respect to the original factor structure. CONCLUSIONS: Results suggest that the GCSQ is a brief, reliable, and valid measure of capability for suicide that can be used in clinic assessment and research.

RESUMO

The interpersonal-psychological theory of suicide posits that elevated pain tolerance is necessary to engage in suicidal behaviour. It is assumed that suicidal intent only leads to lethal (or near lethal) suicide attempts when an individual has the capability to persist the pain involved in dying. The aim of this study was to assess whether objective pain persistence moderates the association between suicide intent and lethality of a recent suicide attempt. Ninety-seven inpatients, who were hospitalized due to a recent suicide attempt, were interviewed regarding lifetime suicide attempts as well as their most recent suicide attempt: Method of attempt, intention to die, medical risk of death, probability of an intervention, and physical condition following the attempt were inquired. Pain persistence was examined using a pressure algometer. Contrary to the expectation, pain persistence did not moderate the association between suicide intent and lethality of a recent suicide attempt, that is, medical risk of death, probability of an intervention, or physical condition following the attempt. Future studies are needed to examine method specific pain persistence for suicidal behaviour in a longitudinal study design.

RESUMO

OBJECTIVE: Exercise dependence has been linked to capability for suicide and suicidal behavior; however, less understood are which facets of exercise dependence confer risk for suicidal behavior and the potential mechanisms of this association. This study examined relationships between exercise dependence, capability for suicide, and past suicidal behavior. METHODS: A sample of 540 individuals recruited via MTurk completed online measures of their exercise dependence, capability for suicide, and history of suicidal behavior. RESULTS: Suicide attempters reported higher levels of continuance in exercise despite physical or psychological consequences, lack of control over exercise, and reductions in other activities due to exercise than nonattempters. Capability for suicide accounted for the relationship between continuance in exercise despite adverse consequences and lifetime number of suicide attempts. CONCLUSIONS: When exercise becomes pathological in the form of exercise dependence, steps should be taken to reduce such engagement due to its observed association with suicidal behavior.

RESUMO

Firearms account for approximately half of all US suicide deaths each year despite being utilized in only a small minority of suicide attempts. We examined the extent to which overall suicide rates fluctuated relative to firearm and non-firearm suicide rates across a period of 16years (1999-2015). We further tested the notion of means substitution by examining the association between firearm suicide rates and non-firearm suicide rates. Lastly, we examined the extent to which the presence of specific laws related to handgun ownership previously shown cross-sectionally to be associated with lower suicide rates (universal background checks, mandatory waiting periods) were associated with an attenuated trajectory in suicide rates across the study period. As anticipated, whereas decreases in firearm suicide rates were associated with decreases in overall suicide rates (b=0.46, SE=0.07, p<0.001), decreases in firearm suicides were not associated with off-setting increases in suicides by other methods (b=-0.04, SE=0.05, p=0.36). Furthermore, the absence of universal background check (b=0.12, SE=0.05, p=0.028) and mandatory waiting period (b=0.16, SE=0.06, p=0.008) laws was associated with a more steeply rising trajectory of statewide suicide rates. These results mitigate concerns regarding means substitution and speak to the potential high yield impact of systematically implemented means safety prevention efforts focused on firearms.

RESUMO

OBJECTIVE: Bondage and discipline, dominance and submission, and sadomasochism (BDSM) practitioners are at increased risk for suicidal thoughts and behaviors. We hypothesized the association between (a) lifetime frequency of BDSM-related sexual behaviors and (b) BDSM identification and suicide attempt status would be mediated by acquired capability components (i.e., fearlessness about death and pain tolerance). Gender differences were examined. METHOD: Participants were 576 BDSM practitioners (meanage = 28.71; 66.7% male) recruited from online BDSM-related groups, cross-sectionally. RESULTS: Among males, the total indirect effect of acquired capability components in the relation between BDSM-related sexual behaviors and suicide attempt status was significant. The specific indirect effect of perceived pain tolerance in the relation between both BDSM-related sexual behaviors and BDSM identification and suicide attempt status was significant. There were no significant effects for females. Additionally, 12% reported a suicide attempt history. CONCLUSION: Among males, BDSM-related sexual behaviors and BDSM identification were associated with increased acquired capability components, which were positively associated with suicide attempt status.

RESUMO

OBJECTIVE: Military sexual trauma (MST) is prevalent among female Veterans and is associated with increased risk for suicidal self-directed violence. Yet research examining processes which contribute to suicidal ideation and attempts among MST survivors has been sparse, focusing primarily on psychiatric symptoms or diagnoses, rather than employing a theory-driven approach. The interpersonal-psychological theory (Joiner, 2005) is a leading theory of suicide that may be particularly relevant for understanding suicidal ideation among female Veterans who have experienced MST. We examined whether constructs derived from the interpersonal-psychological theory of suicide (perceived burdensomeness, thwarted belongingness, and fearlessness about death; Joiner, 2005) were associated with suicidal ideation among female Veterans who had experienced MST, when adjusting for known risk factors for suicide. METHOD: Ninety-two female Veterans with a history of MST completed the Interpersonal Needs Questionnaire, Acquired Capability for Suicide Scale - Fearlessness about Death Scale, and Beck Scale for Suicide Ideation. RESULTS: Perceived burdensomeness, thwarted belongingness, and fearlessness about death were each associated with suicidal ideation in the past week, adjusting for prior suicide attempts, current depressive symptoms, and current symptoms of posttraumatic stress disorder. When including all three interpersonal-psychological constructs in the model, only perceived burdensomeness and fearlessness about death were significantly associated with suicidal ideation. CONCLUSION: These findings provide knowledge regarding interpersonal processes that may contribute to suicidal ideation among this high-risk, yet understudied, population. These results also underscore the importance of assessing for interpersonal-psychological constructs-particularly perceived burdensomeness and fearlessness about death-when working with female Veterans who have experienced MST.

RESUMO

BACKGROUND: According to the interpersonal theory of suicide (1, 2), the difficulties inherently associated with death by suicide deter many individuals from engaging in suicidal behavior. Consistent with the notion that suicide is fearsome, acute states of heightened arousal are commonly observed in individuals immediately prior to lethal and near-lethal suicidal behavior. We suggest that among individuals who possess elevated levels of the capability for suicide, the heightened state of arousal experienced during periods of acute agitation may facilitate suicidal behavior in part because it would provide the necessary energy to approach a potentially lethal stimulus. Among individuals who are low on capability, the arousal experienced during agitation may result in further avoidance. METHODS: In the present project we examine how acute agitation may interact with the capability for suicide to predict suicidality in a large military sample (n = 1,208) using hierarchical multiple regression. RESULTS: Results were in line with a priori hypotheses: among individuals high on capability, as agitation increases, suicidality increases whereas as agitation increases among individuals low on capability, suicidality decreases. Results held beyond the effects of thwarted belongingness, perceived burdensomeness, and suicidal cognitions. CONCLUSIONS: Beyond further substantiating the link between agitation and suicide, findings of the present study provide evidence for the construct validity of the acquired capability as well as offer initial evidence for moderating role of capability on the effect of agitation on suicide. Limitations of the current study highlight a need for future research that improves upon the techniques used in the present study. Implications for science and practice are discussed.

RESUMO

INTRODUCTION: As suicide remains a global public health concern, recent work has sought to characterize mechanisms underlying the transition from suicidal ideation to action. Acquired capability for suicide, or fearlessness about death, has been identified as one key factor underlying this transition; however, understanding how this capability emerges remains limited. This study sought to extend previous work on the correlates of fearlessness about death by examining its relationship with painful and provocative events and emotional reactivity. METHODS: We tested the extent to which trait emotional reactivity and past self-injurious behavior moderated the relationship between assaultive trauma exposure and fearlessness about death in a diverse sample of 273 community adults (aged 18-55, M/SD = 32.77/10.78). RESULTS: A three-way interaction emerged, such that among individuals with heightened emotional reactivity and a history of self-injurious behavior (suicide attempt or non-suicidal self-injury), assaultive trauma was associated with increased fearlessness about death. In contrast, among adults with low emotional reactivity and a history of self-injurious behavior, assaultive trauma was associated with reduced fearlessness about death. CONCLUSIONS: Results suggest that emotional reactivity may be a key dispositional factor that influences how trauma exposure and self-injurious behavior impact fearlessness about death.

RESUMO

Insecure attachment has been identified as a risk factor for adolescent psychopathology and, consequently, for suicidal behavior. We aimed to highlight the relationship between the attachment styles of adolescents and their suicidal behavior and to investigate the role of each parent in the suicidality pathway of adolescents. The sample consisted of 217 adolescent inpatients who were at the highest risk for suicidal behavior and who were hospitalized in the Unit for Intensive Child and Adolescent Psychiatry. Self-report questionnaires assessing their attachment to their parents, their acquired capability for attempting suicide, their suicidality, and a number of traumatic life events were administered. The results showed a higher level of attachment avoidance rather than attachment anxiety among the most at-risk adolescents. An acquired capability for suicide (ACS) mediated the positive correlation between adolescents' attachment avoidance in relation to the mother or father and their suicidality. The suppressive mediating effect of an ACS on the association between attachment anxiety in relation to the father and suicidality was detected. The odds ratio for attempted suicide was more than two times higher for adolescents who were insecurely attached to their father compared to adolescents who were insecurely attached to their mother. Our results confirmed the importance of attachment, especially paternal attachment, in developing suicidality during adolescence. Preventive and clinical interventions should target these important domains with the aim of decreasing suicidality among adolescents.

RESUMO

Introduction: the rate of death by suicide has increased in Mexico, representing a significant public health problem. To prevent and treat this phenomenon, it is crucial to identify reliable suicide risk factors among Mexicans. The Interpersonal Theory of Suicide has demonstrated empirical support for the role of thwarted belongingness, perceived burdensomeness, and acquired capability in the development of suicidal desire and behaviors. The measure of the theory's constructs-the Interpersonal Needs Questionnaire (INQ) and the Acquired Capability for Suicide Scale (ACSS)-has also shown good psychometric qualities. Objective: translate, culturally adapt and validate these instruments. Method: 495 university students from Mexico City participated in two independent samples (n = 239; n = 256). For the INQ, the available version in Spanish was used. For the ACSS, the most current version in English was used. Based on the results from the first sample, items were modified, eliminated, or added for the second sample. Results: the INQ demonstrated good fit (RMSEA = .054, TLI = .97, IFI = .97, NFI = .95) with an internal consistency of .77 and .87 for thwarted belongingness and perceived burdensomeness, respectively. The ACSS obtained similar results (RMSEA = .011, CFI = .99, TLI = .99, IFI = .99, NFI = .91); the internal consistency was .77. Discussion and conclusions: the Spanish version of the instruments display good psychometric properties and can be used to measure the constructs of the interpersonal theory of suicide. However, further replication is needed to support generalizability in other Spanish-speaking populations.


Introducción: la tasa de suicidios ha aumentado en México, esto representa un problema de salud pública. Para prevenir y tratar este fenómeno es crucial identificar predictores confiables del suicidio en mexicanos. La teoría interpersonal del suicidio ha demostrado sustento empírico acerca del papel de la pertenencia fallida, el percibirse como una carga y la capacidad adquirida en el desarrollo del deseo y conducta suicida. Los instrumentos que miden estos constructos­Cuestionario de Necesidades Interpersonales (INQ, por sus siglas en inglés) y Escala de Capacidad Adquirida para el Suicidio (ACSS, por sus siglas en inglés)­han mostrado buenas cualidades psicométricas. Objetivo: traducir, adaptar culturalmente y validar estos instrumentos. Método: 495 estudiantes universitarios de la Ciudad de México participaron en dos muestras independientes (n = 239; n = 256). Para el INQ se usó la versión disponible en español. Para la ACSS, se usó la versión más actualizada en inglés. Según los resultados de la primera aplicación, se modificó la redacción de algunos ítems, se eliminaron otros y se agregaron nuevos para la segunda aplicación. Resultados: el INQ alcanzó índices de buen ajuste (RMSEA = .054, TLI = .97, IFI = .97, NFI = 95) con consistencia interna de .77 y .87 para pertenencia fallida y percibirse como carga, respectivamente. La ACSS obtuvo resultados similares (RMSEA = .011, CFI = 99, TLI = .99, IFI = .99, NFI = .91); la consistencia interna fue .77. Discusión y conclusiones: las versiones en español de los instrumentos mostraron buenas propiedades psicométricas y pueden usarse para medir los constructos de la Teoría Interpersonal del Suicidio. Sin embargo, se requiere replicar el estudio para apoyar la generalización a otras poblaciones de habla hispana.

RESUMO

BACKGROUND: Suicidal ideation is highly prevalent in Major Depressive Disorder (MDD). However, the factors determining who will transition from ideation to attempt are not established. Emerging research points to suicide capability (SC), which reflects fearlessness of death and increased pain tolerance, as a construct mediating this transition. This Canadian Biomarker Integration Network in Depression study (CANBIND-5) aimed to identify the neural basis of SC and its interaction with pain as a marker of suicide attempt. METHODS: MDD patients (n = 20) with suicide risk and healthy controls (n = 21) completed a self-report SC scale and a cold pressor task measuring pain threshold, tolerance, endurance, and intensity at threshold and tolerance. All participants underwent a resting-state brain scan and functional connectivity was examined for 4 regions: anterior insula (aIC), posterior insula (pIC), anterior mid-cingulate cortex (aMCC) and subgenual anterior cingulate cortex (sgACC). RESULTS: In MDD, SC correlated positively with pain endurance and negatively with threshold intensity. Furthermore, SC correlated with the connectivity of aIC to the supramarginal gyrus, pIC to the paracingulate gyrus, aMCC to the paracingulate gyrus, and sgACC to the dorsolateral prefrontal cortex. These correlations were stronger in MDD compared to controls. Only threshold intensity mediated the correlation between SC and connectivity strength. LIMITATIONS: Resting-state scans provided an indirect assessment of SC and the pain network. CONCLUSIONS: These findings highlight point to a neural network underlying SC that is associated with pain processing. This supports the potential clinical utility of pain response measurement as a method to investigate markers of suicide risk.

RESUMO

Recent work has identified fearlessness about suicide, rather than fearlessness about death, as more theoretically relevant in the assessment of capability for suicide and thus a more appropriate construct of measurement. The aim of the current project was to develop and validate a scale specifically assessing fearlessness about suicide. Across two studies, support for a 7-item, single-factor structure of the Fearlessness About Suicide Scale (FSS) emerged. The FSS factor structure demonstrated a good fit in the first study and was replicated in the second study. Measurement invariance was examined across those identifying as men and women and found to be comparable. The FSS also demonstrated test-rest reliability and good convergent and divergent validity in community and undergraduate samples. Overall, findings indicate that the FSS has a replicable factor structure that generalizes across those identifying as men and women and may better assess components of capability for suicide than existing scales.

RESUMO

INTRODUCTION: The current study aimed to explicate the role of dissociation in the capability and suicide relationship by examining how lifetime and state-based acute dissociation contributes to capability for suicide using a multi-method approach of self-report and augmented reality (AR) laboratory tasks. METHOD: Participants (N = 145) were students recruited for course credit at a southern university. Participants completed self-report and laboratory AR dissociative induction tasks. Correlations and mediation analyses were conducted to test hypotheses using SPSS v. 26 and PROCESS Macro. RESULTS: There was a significant indirect effect on capability and suicidal ideation via acute dissociation (ß = 0.035, SE = 0.02, 95% CI = 0.001, 0.095). Additionally, there was a significant indirect effect on capability and suicide attempt(s) via dissociation (ß = 0.19, SE = 0.10, 95% CI = 0.044, 0.449). CONCLUSIONS: As prior theories suggest, dissociation may augment feeling disconnected from the body and may temporarily impact capability to render a suicidal act as more probable. The presence of dissociation after a painful and provocative attempt may increase capability and pain tolerance. Implications of these findings include the consideration of dissociation as a pertinent factor in the assessment and treatment of suicide and the role of AR in aiding the exploration of suicide correlates.

RESUMO

OBJECTIVE: This study examined the path model predicting suicide attempts (SA) by interpersonal need for suicide desire, acquired capability for suicide, the emotion dysregulation, and depression symptoms in people admitted to hospitals for medical treatment. METHODS: A total of 344 participants (200 depressed patients with attempted suicide, 144 depressed patients with suicidal ideation) were enrolled for this study. Depression, anxiety, emotion regulation, interpersonal needs, and acquired capability for suicide were evaluated. A model with pathways from emotion regulation difficulties and interpersonal needs to SA was proposed. Participants were divided into two groups according to the presence of SA or suicidal ideation. RESULTS: Acquired capability for suicide mediated the path from depression to SA. In the path model, difficulties in emotion regulation and interpersonal needs predicted depression significantly. Although depression itself was not significantly related to acquired capability for suicide, depression was significantly related to acquired capability for suicide in suicide attempter group. CONCLUSION: Interventions with two factors affecting SA will clarify the suicide risk and contribute to finding risk factors.

RESUMO

Suicide is a major cause of death in Eating Disorders (EDs) and particularly in anorexia nervosa (AN). The aim of the present mini-review was to summarize the literature focusing on the interpersonal-psychological theory of suicide (IPTS) by Thomas E. Joiner, as applied to explain suicidal risk in EDs. PubMed database was used to search articles focused on IPTS in EDs; 10 studies were eventually included. The majority of the included studies reported data from the same sample, even though the hypotheses and analyses for each study were unique. The investigated suicidal outcomes were suicidal ideation (SI) (40%), non-suicidal self-injury (10%), suicide attempt (40%) and suicide (10%). In ED patients Perceived Burdensomeness (PB) may play an important role, especially regarding SI risk. ED patients may feel like a burden to their close ones, and actually some of the ED symptoms may be an expression of anger and hate against the self. Overall, currently available research has supported some IPTS derived predictions (i.e., ED symptoms may increase PB and thereby SI), but not others (i.e., the elevated suicide rate in AN may be due to higher acquired capability for suicide). Further research on IPTS tenets as well as on other theoretical perspectives and constructs (e.g., interoceptive awareness), hopefully with a longitudinal design and adequate follow-up duration, might allow a more thorough understanding of the complex topic of suicidal behavior in ED patients.

RESUMO

To prevent suicidal behaviors, it is crucial to understand the mechanisms and processes that enable an individual to act on suicidal thoughts. Suicide capability, which involves an increased pain tolerance and fearlessness of death, is a critical factor that enables an individual to endure the physical pain necessary to make a lethal suicide attempt. Extant research has largely conceptualized suicide capability as developing linearly in response to painful and provocative experiences, but the emerging literature on the temporal dynamics of suicide has been challenging the notion of linearity in suicide risk. Few studies have directly measured and compared changes in suicide capability in response to rumination on different affective states. We sought to experimentally test if rumination in the context of low vs. high arousal emotions will prompt distinct changes in two core components of suicide capability: pain tolerance and fearlessness of death on two undergraduate student samples. In both studies, participants provided measures of subjective emotional state as well as pain threshold, tolerance, and persistence before and after completing experimental manipulations which included both emotion and rumination induction procedures. In the second study, measures of fearlessness about death and physiological arousal (heart rate) were added to the experimental procedures. We found significant decreases in pain threshold, tolerance, and persistence following the experimental manipulations but found no main effects of rumination or suicide risk. These findings suggest that suicide capability can fluctuate but these changes may occur through a different mechanism and/or differ between individuals at varying levels of suicide risk.

RESUMO

Fears of pain, injury, and death may represent key barriers to acting on suicidal thoughts. Dissociation, which involves a disconnection from one's body, may reduce fears and sensations of pain associated with harming the body, in turn facilitating suicide attempts. This study examined whether dissociation differentiated individuals with a history of suicide attempts from those with a history of suicide ideation, and investigated whether other relevant constructs explain this relationship. Sample 1 included 754 undergraduates (Mage = 21, 79% female) who completed a battery of self-report measures. Sample 2 included 247 undergraduates (Mage = 19, 74% female) who completed a self-report measure of dissociation, a clinical interview regarding suicide history, and four counterbalanced behavioral pain tolerance tasks. In both samples, dissociation was elevated in lifetime attempters compared to ideators (d = 0.28; d = 0.46; ps = 0.01) and slightly elevated in lifetime ideators compared to nonsuicidal individuals (d = 0.19, p = .02; d = 0.24, p = .47), though this effect was non-significant in the latter sample. In Sample 1, dissociation no longer differentiated attempters from ideators after controlling for clinical covariates. In Sample 2, dissociation was unrelated to behavioral pain tolerance tasks, and these tasks did not account for the association between dissociation and attempts. Overall, dissociation differentiated individuals with a history of suicide attempts from those with ideation alone in both samples. Pain tolerance did not explain this association; instead, it is possible that the relationship of dissociation to suicide attempts is due to "third variables" associated with both phenomena, such as symptoms of borderline personality disorder or posttraumatic stress disorder.

RESUMO

Acquired capability for suicide is associated with increased suicide risk and behaviors, but little research has examined factors that may qualify this relationship. Body investment is proposed as one such factor, as it may engage self-preservation instincts and serve as a buffer to capability for suicide. It was expected that facets of body investment (body feelings, body care, comfort with touch, and body protection) would moderate the relationship between acquired capability for suicide and suicide attempts. The current study included a sample of 1,150 undergraduate students with a mean age of 19.74 (3.44). The majority of the sample identified as female (71%) and White/Caucasian (78%). Participants completed self-report measures of body investment (Body Investment Scale [BIS]), acquired capability (Acquired Capability for Suicide Scale [ACSS]), suicide thoughts and attempt history (Self-Harm Behavior Questionnaire [SHBQ]), and demographic information. Four moderation analyses were run using the PROCESS macro; one for each body investment subscale. All facets of body investment showed significant moderation except for body care. Acquired capability was significantly associated with suicide attempts when body feelings, comfort with touch, and body protection were low, but not when they were high. Results indicate that fostering aspects of body investment may be important for suicide prevention.

RESUMO

BACKGROUND: Leading theoretical explanations for suicide state that for suicide death to occur, a person must have sufficient capability to enact an attempt. Exposure to painful and provocative events is hypothesized to play an important role in acquiring the capability for suicide over a lifetime. Unfortunately, assessment tools for painful and provocative events have focused solely on the frequency of events, neglecting the potential contributions of perceived impact. Further, past measurements have used predetermined items for painful and provocative events thereby neglecting other relevant events. The current study uses visual analog scales (VAS) to assess both the frequency and impact of painful and provocative events and how these contribute to the capability for suicide. METHOD: Data were collected from 787 adults via Amazon's online platform. RESULTS: Findings indicated that the frequency VAS and impact VAS both had a moderate correlation with the original Painful and Provocative Events Scale. Greater scores on the frequency VAS were associated with increased capability, whereas lower scores on the subjective impact VAS were associated with increased capability scores. Both VAS independently predicted capability above and beyond the PPES. LIMITATIONS: Temporal or causal associations are unable to be drawn due to cross-sectional data. In addition, the sample was largely homogenous (White = 72%, female = 63.5%), limiting generalizability. CONCLUSIONS: These initial findings demonstrate individuals who perceive painful and provocative events as being less impactful may have increased capability, and that VAS may be appropriate to approximate the impact and frequency of painful and provocative events.
