A Brief Report on the Assessment of Distress Tolerance: Are We Measuring the Same Construct?

I know why the caged bird sings: Distress tolerant individuals show greater resting state connectivity between ventromedial prefrontal cortex and right amygdala as a function of higher vagal tone

BACKGROUND

Intolerance to psychological distress is associated with various forms of psychopathology, ranging from addiction to mood disturbance. The capacity to withstand aversive affective states is often explained by individual differences in cardiovagal tone as well as resting state connectivity of the ventromedial prefrontal cortex (vmPFC), a region involved in the regulation of emotions and cardio-autonomic tone. However, it is unclear which brain regions involved in distress tolerance show greater resting state functional connectivity (rsFC) as a function of resting heart rate variability (HRV).

METHODS

One-hundred and twenty-six adults, aged 20 to 83.5 years, were selected from a lifespan cohort at the Nathan Kline Institute-Rockland Sample. Participants' distress tolerance levels were assessed based upon performance on the Behavioral Indicator of Resiliency to Distress (BIRD) task. Artifact-free resting-state functional brain scans collected during separate sessions were used. While inside the scanner, a pulse oximeter was used to record beat-to-beat intervals to derive high-frequency heart rate variability (HF-HRV). The relationship between HF-HRV and vmPFC to whole brain functional connectivity was compared between distress tolerant (BIRD completers) and distress intolerant (BIRD non-completers).

RESULTS

Groups did not differ in their history of psychiatric diagnosis. Higher resting HF-HRV was associated with longer total time spent on the BIRD task for the entire sample (r = 0.255, p = 0.004). After controlling for age, gender, body mass index, head motion, and gray matter volume. Distress tolerant individuals showed greater rsFC (p < 0.005 (uncorrected), k = 20) between the vmPFC and default-mode network (DMN) hubs including posterior cingulate cortex/precuneus, medial temporal lobes, and the parahippocampal cortex. As a function of higher resting HF-HRV greater vmPFC connectivity was observed with sub-threshold regions in the right amygdala and left anterior prefrontal cortex, with the former passing small volume correction, in distress tolerant versus distress intolerant individuals.

CONCLUSION

In a lifespan sample of community-dwelling adults, distress tolerant individuals showed greater vmPFC connectivity with anterior and posterior hubs of the DMN compared to distress intolerant individuals. As a function of greater HF-HRV, distress tolerant individuals evidenced greater vmPFC with salience and executive control network hubs. These findings are consistent with deficits in neural resource allocation within a triple network resting amongst persons exhibiting behavioral intolerance to psychological distress.

The relationship between psychiatric symptoms and affective forecasting bias

BACKGROUND AND OBJECTIVES

Affective forecasting (AF) is the prediction of future emotional states. Negatively biased affective forecasts (i.e., overestimating negative affect) have been associated with trait anxiety, social anxiety, and depression symptoms, but few studies have tested these relationships while covarying commonly co-occurring symptoms.

METHODS

In this study, participants (N = 114) completed a computer game in dyads. Participants were randomized into one of two conditions: a condition in which they were led to believe they were at-fault for losing their dyad money (n = 24 dyads) or a condition in which they were told no one was at fault (n = 34 dyads). Prior to the computer game, participants forecasted their affect for each potential game outcome.

RESULTS

More severe social anxiety, trait-level anxiety, and depressive symptoms were all associated with more negative AF bias in the at-fault relative to the no-fault condition, and this effect persisted when controlling for other symptoms. Cognitive and social anxiety sensitivity was also associated with more negative AF bias.

LIMITATIONS

The generalizability of our findings is innately limited by our non-clinical, undergraduate sample. Future work should replicate and extend our research in more diverse populations and clinical samples.

CONCLUSIONS

Overall, our results support that AF biases are observed across a range of psychopathology symptoms and associated with transdiagnostic cognitive risk factors. Future work should continue investigating the etiological role of AF bias in psychopathology.

Understanding the relationship between distress intolerance and problematic Internet use: The mediating role of coping motives and the moderating role of need frustration

INTRODUCTION

There is emerging research interest in exploring the relationship between distress intolerance and problematic Internet use, yet most of the existing studies are limited by cross-sectional design, convenience sampling method, and poor understanding of the potential mediating and moderating factors involved. Based on the distress intolerance theory of addictive behavior and the theory of compensatory internet use, this study investigated a moderated mediation model to explain the impact of distress intolerance on problematic Internet use in adolescents.

METHODS

A three-wave longitudinal survey was conducted with 709 adolescents in Shanghai, China. The gender distribution was even, 50.2% were boys and 49.8% were girls. The mean age at T1 was 14.79 years (SD = 2.87).

RESULTS

Distress intolerance at Time 1 was found to positively predict problematic Internet use at Time 3. This prospective relation was mediated by adolescents' coping motives for Internet use at Time 2. Further, the mediation effect of coping motives for Internet use was moderated by need frustration at Time 2. The moderated mediation model was statistically equivalent for both genders.

CONCLUSIONS

Findings of this study contribute to new knowledge and have practical implications for prevention and intervention of adolescent problematic Internet use.

Distress tolerance across substance use, eating, and borderline personality disorders: A meta-analysis

BACKGROUND

Distress tolerance (DT) has received increased attention in recent years due to its purported role in dysregulated behaviours and their clinical manifestations, such as problematic substance use (PSU), disordered eating behaviours (e.g., binge-eating and purging; DEB), and borderline personality disorder (BPD) symptomatology. Despite the proposed transdiagnostic utility of DT across PSU, DEB, and BPD, there has yet to be a systematic and comprehensive examination characterising and comparing its association with this class of impulsive-type psychopathology.

METHODS

A systematic search was conducted across five electronic databases using search terms designed to capture extant literature on the association between DT and PSU, DEB, and BPD symptomatology. A series of meta-analyses were undertaken on correlation coefficients from 81 studies to examine the association between DT and each psychopathology domain, as well as impulsive-type psychopathology overall. Moderator analyses were conducted to examine whether these relationships were moderated by DT measurement type, sample type, age, and gender.

RESULTS

DT shared significant, negative, medium correlations with PSU (r = -.18,), DEB (r = -.20), and BPD symptomatology (r = -.27). The magnitude of these associations was not significantly different across the three psychopathology domains, supporting transdiagnostic conceptualisation. DT measurement type, age, and sample type moderated several of these indicated relationships.

LIMITATIONS

The majority of studies were conducted in adult samples from Western countries, limiting understanding of these relationships across development and different cultures.

CONCLUSIONS

The present findings support the putative transdiagnostic role of DT across PSU, DEB, and BPD, which may ultimately inform novel, cross-cutting interventions.

The Role of Emotional Distress Tolerance on Fear Responding in a Heights-Fearful Sample: Perceived Versus Actual Behavior

Emotional distress tolerance (EDT)-or the ability to withstand negative emotional states-is considered a transdiagnostic risk factor for psychopathology. Although EDT is theorized to play a role in anxiety development and maintenance, research aiming to delineate the relationship between anxiety and EDT is lacking. The current study tested whether self-reported EDT predicted self-reported and actual avoidance in the presence of feared stimuli using a heights-fearful sample. Moreover, the study tested whether EDT predicted other in-the-moment fear responses, such as peak anxiety, anxious cognitions, and bodily sensations. Participants (N = 128) completed questionnaires assessing fear of heights, negative affect, anxious cognitions, and bodily sensations, as well as two heights behavioral avoidance tasks (BATs). Results demonstrated that EDT did not predict actual avoidance or other in-the-moment fear responses, except for peak anxiety in one BAT. However, EDT predicted self-reported avoidance of heights beyond fear of heights and negative affect. Taken together, results suggest that perception of ability to tolerate emotional distress predicts perception of avoidance of heights, but not actual avoidance of heights or reactions to heights (with the exception of peak anxiety in one BAT). Given these findings, self-reported EDT may not adequately predict how individuals react in anxiety-provoking situations.

Differences in Distress Intolerance Among Daily and Intermittent Smokers

INTRODUCTION

Distress intolerance is an important risk factor for smokers. Smokers have greater problems tolerating distress than nonsmokers, and distress intolerance is theoretically an important predictor of early lapse. However, much of the distress intolerance research has been conducted on daily smokers. Understanding distress intolerance in nondaily or intermittent smokers may help elucidate whether distress intolerance is a function of current smoking habits.

AIMS AND METHODS

Daily (n = 36) and intermittent (n = 28) smokers completed behavioral distress intolerance tasks (breath holding, mirror tracing persistence, and image persistence) along with self-report measures of both general and smoking-specific distress intolerance. They also completed 1 week of ecological momentary assessment where positive and negative affect were assessed along with momentary distress intolerance, at both random times (7×/day) and immediately prior to smoking a cigarette.

RESULTS

Results found no differences between intermittent and daily smokers on behavioral distress intolerance tasks or general self-reported distress intolerance. Daily smokers reported greater self-reported smoking-specific distress intolerance compared to intermittent smokers. In addition, across both smoker groups, momentary distress intolerance was higher at smoking compared to random sessions, and low positive affect predicted greater momentary distress intolerance specifically for intermittent smokers prior to smoking.

CONCLUSIONS

The lack of differences between daily and intermittent smokers on general distress intolerance measures suggests that distress intolerance abilities and self-perceptions are not a function of higher levels of current smoking. However, the contextual variation in momentary distress intolerance is worth further exploration in both daily and intermittent smokers.

IMPLICATIONS

The overall lack of differences between intermittent and daily smokers on distress intolerance tasks and self-report measures suggests that daily smoking is not associated with lower abilities to manage or tolerate distress at the individual difference level. However, understanding fluctuations in distress intolerance across time and context is crucial, as smokers' perceptions of their abilities to manage distress shift based on affect and smoking contexts. Stabilizing or increasing self-efficacy in tolerating distress during daily life is likely an important avenue for future research.

Trait Versus Task-Induced Emotional Reactivity and Distress Intolerance in Hoarding Disorder: Transdiagnostic Implications

Evidence from analogue samples suggests that deficits in emotional functioning, namely elevated emotional reactivity and distress intolerance, are implicated in the development and maintenance of hoarding disorder. We aimed to extend previous research in this area by investigating emotional reactivity and distress intolerance in a sample of individuals diagnosed with hoarding disorder (n = 24) in comparison to clinical controls (n = 21) and nonclinical community controls (n = 26) using a combination of self-report, physiological, and behavioral measures. We found that trait distress intolerance was significantly and independently associated with greater hoarding severity. The hoarding and clinical control groups reported more trait emotional reactivity and distress intolerance than the community control group, but did not differ from each other on these traits. The hoarding group reported more subjective distress before beginning a frustrating behavioral task, but did not evidence more physiological arousal. Moreover, the hoarding group experienced similar increases in distress during the task and did not differ from either group in regard to time persisting on this task. The clinical control group, however, terminated the frustrating task significantly faster than the community control group, who tended to persist until the task timed out. Lastly, trait distress intolerance evidenced a small-to-moderate but nonstatistically significant independent relationship with task persistence time. Given the desynchrony between subjective distress and physiological arousal, we encourage researchers to utilize multimodal assessment in the future. We also suggest that clinicians start to use behavioral experiments, as has been done with other psychological disorders, to improve distress intolerance among persons who experience hoarding disorder.

A Psychometric Evaluation of the Distress Intolerance Index for Youth

Distress Intolerance (DI), defined as the perceived inability to tolerate negative mood states and experiential discomfort, has been posited as a vulnerability factor for several anxiety and emotional disorders. There is a relative paucity of research on DI in youth samples, in large part due to the absence of a psychometrically sound measure of DI in youth. The current study evaluated the psychometric properties of the Distress Intolerance Index for Youth (DII-Y) and the Distress Intolerance Index for Youth-Parent Report (DII-Y-P), which are downward extension adaptations of the adult-oriented Distress Intolerance Index (McHugh & Otto, 2012). Participants were 176 youth (ages 9-17) and their parents who were seeking treatment for child anxiety problems. The DII-Y and DII-Y-P demonstrated good-to-excellent internal consistency. Convergent validity of the DII-Y and the DII-Y-P was supported by large, significant associations with measures of intolerance of uncertainty, as well as with anxiety sensitivity in the case of the DII-Y. Discriminant validity of the DII-Y and the DII-Y-P was supported by the absence of significant direct relationships with a measure of defiant behavior. Results support the use of DII-Y and DII-Y-P as reliable and valid instruments for the assessment of youth DI, providing a practical and efficient tool to study DI as a potential factor in the etiology and maintenance of youth anxiety and emotional disorders.

Cross-Domain Assessment of Distress Intolerance: Associations With Borderline Personality Disorder Features

Distress tolerance (DT) is central to major etiological theories of, and popular treatments for, borderline personality disorder (PD), but empirical evidence for the connection between DT and borderline PD is inconclusive. Such inconsistency is partly due to limited concordance across DT indices from different measurement domains (e.g., behavioral, physiological). In a student sample (N = 267), we assessed subjective perceptions of DT capabilities, task performance on a distressing laboratory challenge, and borderline pathology. Subjective and behavioral indices of DT were largely unrelated. Further, borderline PD features were moderately associated with self-perceived DT (r = -.53); in contrast, they were weakly related to performance on the DT task (r = -.09). We conclude that there is mixed evidence for an association between borderline pathology and DT. Further, we propose a systematic approach to examining the construct validity of DT in multimethod, multimeasure research that might resolve the equivocal results from prior work.

A network conceptualization of the multiple facets of distress tolerance

BACKGROUND AND OBJECTIVES

Using a network analysis (NA) approach, the current study examined the relations among different facets of Distress Tolerance (DT). The NA approach quantifies and displays relations among variables in a visual network consisting of nodes (symptoms) and edges (partial correlations between symptoms).

DESIGN

An exploratory NA approach evaluated how manifestations of DT uniquely and systematically relate to one another.

METHODS

Undergraduate students (N = 288) completed 10 commonly used measures of DT including cognitive, behavioral, and self-report measures.

RESULTS

Results indicated all relations in the network were positive apart from social sensitivity and suppression. Further, individual DT facets did not form distinct community structures (nodes that cluster together and thus have stronger relations with each other than other nodes in the network).

CONCLUSIONS

The lack of community structures suggests that DT is a general ability to tolerate distress that is comprised of many different facets rather than the idea that DT is hierarchical and comprised of distinct domains; a current debate within the literature. The self-reported ability to tolerate life demands and tasks was the most influential facet in the overall network suggesting the Frustration Discomfort Scale may be the best global measure of DT.

Frustration Tolerance and Personality Traits in Patients With Substance Use Disorders

Previous research has suggested the prevalence of certain personality traits, some of which are related to a disorganized attachment, in substance abuse disorders. Further, frustration tolerance (FT) has been proposed as an important factor in addiction, both at the inception-following the "self-medication" hypothesis-and regarding treatment compliance. In turn, an inadequate response to frustrating events has been also associated with a disrupted attachment. Our goal is to explore the mediational role of FT in the relationship between personality traits and two different treatments for substance addiction: therapeutic community (TC) and ambulatory treatment (AT). Eighty-four subjects with substance abuse disorder were recruited in total (22 female), including 46 volunteers (13 female) in TC and 38 (9 female) in AT. They were assessed with Rosenzweig's test for FT and the Millon Clinical Multiaxial Inventory-III (MCMI-III) test to evaluate personality factors. By comparing with a control sample (335 volunteers, 268 female), we found that FT was lower in patients. Between therapeutic groups, FT was significantly lower in TC. Depressive, antisocial, sadistic, negativistic, schizotypal, borderline, paranoid, anxiety, dysthymia, alcohol use, drug use, posttraumatic stress disorder (PTSD), thought disorder, and delusional disorder traits were suggestive of pathology in the clinical samples and were significantly different between control, AT, and TC groups. Further, anxiety and PTSD traits were higher in TC than in AT. A mediational analysis revealed that the effect of anxiety and PTSD scales on therapeutic group was partially mediated by FT. In conclusion, FT and its interplay with personality traits commonly related to disorganized attachment (anxiety and PTSD) might be important factors to consider within therapeutic programs for persons with substance addiction.

Reduction of Distress Intolerance With Salutotherapeutic Interventions: Results From a Randomized Controlled Clinical Trial

Background

Distress tolerance is the ability to pursue one’s goals in the presence of (chronic) stressors, hardship, adversities and negative internal states, and psychological distress. By contrast, distress intolerance is a transdiagnostic indicator of mental illness and a mediator in coping with problems in life, work demands, or stress in general. There is a lack of data regarding intervention strategies. The objective of the present study is to test the differential effects of two treatment approaches: “regeneration fostering” versus “resistance training.”

Methods

Inpatients of a psychosomatic hospital were randomly allocated to either a resistance training group therapy (n = 65)—that is, active coping with demands and endurance—or a regeneration fostering group therapy (n = 62)—that is, recovery, mindful indulgence, and creative activities. They were compared with a group of patients who received treatment as usual (n = 43), without special treatments for distress intolerance, and the outcome was measured with the “Distress Intolerance Scale.” One-way and repeated measure analyses of variance and paired t tests were used for the analysis.

Results

The “regeneration” group showed a significant improvement in distress intolerance, whereas there was no significant change for the treatment-as-usual group and in the “resistance” group. Post hoc tests were conducted with paired sample t tests for pre–post comparisons for each group. No differences were found for the treatment-as-usual group (mean difference: 0.03, SD (mean difference): 0.89; t(42) = 0.266, p = 0.792, d = 0.04) and for the resistance group (mean difference:−0.07, SD (mean difference): 0.73; t(63) = −0.736, p = 0.464, d = 0.08). The regeneration group showed a significant decline in distress intolerance (mean difference: 0.29, SD (mean difference): 0.72; t(61) = 3.156, p = 0.002, d = 0.38).

Conclusions

In the treatment of distress intolerance, it seems promising to focus on positive psychology interventions and resources. Limitations of the study are that it was conducted with psychosomatic inpatients only and that no follow-up data are available.

The Influence of a Personal Values Intervention on Cold Pressor-Induced Distress Tolerance

Research has demonstrated that values and acceptance interventions can increase distress tolerance, but the individual contribution of each remains unclear. The current study examined the isolated effect of a values intervention on immersion time in a cold pressor. Participants randomized to Values (n = 18) and Control (n = 14) conditions completed two cold pressor tasks, separated by a 30-min values or control intervention. Immersion time increased 51.06 s for participants in the Values condition and decreased by 10.79 s for those in the Control condition. Increases in self-reported pain and distress predicted decreases in immersion time for Control, but not Values, participants. The best-fitting model accounted for 39% of the variance in immersion time change. Results suggest that a brief isolated values exercise can be used to improve distress tolerance despite increased perceptions of pain and distress, such that values alone may be sufficient to facilitate openness to difficult experiences.

Behavioral Assessment of the Negative Emotion Aspect of Distress Tolerance: Tolerance to Emotional Images

The current behavioral tasks assessing distress tolerance measure tolerance to frustration and tolerance to physical discomfort, but do not explicitly assess tolerance to negative emotion. We closely evaluated the conceptual distinctions between current behavioral tasks and self-report tasks assessing distress tolerance, and then developed a new behavioral distress tolerance task called the Emotional Image Tolerance (EIT) task. The EIT task retains elements of existing behavioral tasks (e.g., indices of persistence) while augmenting the reliability and content sufficiency of existing measures by including multiple trials, including a variety of negative affect stimuli, and separating overall task persistence from task persistence after onset of distress. In a series of three studies, we found that the EIT correlated with extant behavioral measures of distress tolerance, the computerized mirror-tracing task and a physical cold pressor task. Across all of the studies, we also evaluated whether the EIT correlated with self-report measures of distress tolerance and measures of psychopathology (e.g., depression, anxiety, and binge eating). Implications for the refinement of the distress tolerance construct are discussed.
