A Psychometric Examination of the Anagram Persistence Task: More Than Two Unsolvable Anagrams May Not Be Better.

The purpose of this investigation was to examine a single-anagram, a double-anagram, and multi-anagram versions of the Anagram Persistence Task (APT) for factorial validity, reliability, and convergent validity. Additionally, a battery of intelligence tests was administered to examine convergent validity. Based on an unrestricted factor analysis, two factors were uncovered from the 14 anagram (seven very difficult and seven very easy) response times: test-taking persistence and verbal processing speed. The internal consistency reliabilities for the single-anagram, double-anagram, and multi-anagram (seven difficult anagrams) measures were .42, .85, and .86, respectively. Furthermore, all three versions of the APT correlated positively with intelligence test performance (r ≈ .22). However, the double-anagram and multi-anagram versions also evidenced negative, nonlinear effects with intelligence test performance (r ≈ -.15), which suggested the possibility of testee adaptation. Taking psychometrics and administration time into consideration, simultaneously, the double-anagram version of the APT may be regarded as preferred.

Distress tolerance: Associations with trauma and substance cue reactivity in low-income, inner-city adults with substance use disorders and posttraumatic stress.

Cue reactivity has great potential to advance our understanding of posttraumatic stress disorder (PTSD), substance use disorder (SUD), and PTSD/SUD comorbidity. The present investigation examined distress tolerance (DT) with regard to trauma and substance cue reactivity. Participants included 58 low-income, inner-city adults (49.1% women; Mage = 45.73, SD = 10.00) with substance dependence and at least 4 symptoms of PTSD. A script-driven cue reactivity paradigm was utilized. Four DT measures were administered, including the Distress Tolerance Scale (DTS), Mirror-Tracing Persistence Task (MTPT), Breath-Holding Task (BH), and Paced Auditory Serial Addition Task (PASAT). Lower DT, as indexed by MTPT duration, was significantly predictive of greater levels of self-reported substance cravings/urges in response to trauma cues, above and beyond covariates. Lower DTS scores predicted lower levels of self-reported control/safety ratings in response to substance cues. None of the DT indices was significantly predictive of heart rate variability. Clinical and research implications are discussed. (PsycINFO Database Record

Multimodal Examination of Distress Tolerance and Suicidality in Acute-Care Psychiatric Inpatients

The present investigation examined associations between distress tolerance, examined multimodally via self-report and behavioral indices, and suicidality. Participants were 102 psychiatric inpatients (44.1% women; Mage=33.9, SD=10.8). Distress tolerance was measured via the Distress Tolerance Scale (DTS), Mirror-Tracing Persistence Task (MTPT), and Breath-Holding Task. Suicidality was defined as: number of past suicide attempts, self-reported suicidal ideation severity, and suicidality as reason for the current hospital admission. When DT indices were examined concurrently, only MTPT was negatively associated with number of past suicide attempts; perceived DT (DTS) was negatively associated with suicidal ideation severity and suicidality as the reason for current admission.

Too hot to carry on? Disinclination to persist at a task in a warm office environment

We investigated the effect of an elevated ambient temperature on performance in a persistence task. The task involved the coding of incorrect symbols and participants were free to decide how long to spend performing this task. Applying a between-subject design, we tested 125 students in an office-like environment in one of the three temperature conditions. The comfort condition (Predicted Mean Vote [PMV] = 0.01) featured an average air temperature of 24 °C. The elevated ambient temperature condition was 28 °C (PMV = 1.17). Condition three employed an airstream of approximately 0.8 m/s, intended to compensate for performance decrements at the elevated air temperature (28 °C, PMV = 0.13), according to Fanger’s thermal comfort equation. Participants in the warm condition were significantly less persistent compared with participants in the control and compensation conditions. As predicted by the thermal comfort equation, the airstream seemed to compensate for the higher temperature. Participants’ persistence in the compensation and comfort conditions did not differ.Practitioner Summary: A laboratory experiment involving a simulated office environment and three ambient temperature conditions (24 °C, 28 °C and 28 °C plus airstream) showed that persistence at a task is significantly impaired at 28 °C. An airstream of 0.8 m/s at 28 °C compensated for the disinclination to persist with the task.

The Use of the Mirror Tracing Persistence Task as a Measure of Distress Tolerance in Generalized Anxiety Disorder

Behavioral tasks offer an objective index of processes associated with psychopathology. The mirror tracing persistence task (MTPT) has been used as a measure of distress tolerance, or the ability to endure negative internal states. In generalized anxiety disorder (GAD), a poor ability to tolerate aversive internal states may relate to the inability to adaptively regulate emotion. This study examined if those with GAD exhibit lower distress tolerance compared to controls as evidenced by length of time persisting on the MTPT. Participants underwent diagnostic interviews to determine the presence of absence of GAD and following group assignment, completed the MTPT. Results demonstrated that the groups differed significantly in time spent persisting on the task, with controls persisting longer than those with GAD, supporting the hypothesis that individuals with GAD exhibit lower distress tolerance than controls. These results provide support for the use of behavioral assessments as potential markers of distress tolerance.

Neural processes underlying cultural differences in cognitive persistence

Self-improvement motivation, which occurs when individuals seek to improve upon their competence by gaining new knowledge and improving upon their skills, is critical for cognitive, social, and educational adjustment. While many studies have delineated the neural mechanisms supporting extrinsic motivation induced by monetary rewards, less work has examined the neural processes that support intrinsically motivated behaviors, such as self-improvement motivation. Because cultural groups traditionally vary in terms of their self-improvement motivation, we examined cultural differences in the behavioral and neural processes underlying motivated behaviors during cognitive persistence in the absence of extrinsic rewards. In Study 1, 71 American (47 females, M=19.68 years) and 68 Chinese (38 females, M=19.37 years) students completed a behavioral cognitive control task that required cognitive persistence across time. In Study 2, 14 American and 15 Chinese students completed the same cognitive persistence task during an fMRI scan. Across both studies, American students showed significant declines in cognitive performance across time, whereas Chinese participants demonstrated effective cognitive persistence. These behavioral effects were explained by cultural differences in self-improvement motivation and paralleled by increasing activation and functional coupling between the inferior frontal gyrus (IFG) and ventral striatum (VS) across the task among Chinese participants, neural activation and coupling that remained low in American participants. These findings suggest a potential neural mechanism by which the VS and IFG work in concert to promote cognitive persistence in the absence of extrinsic rewards. Thus, frontostriatal circuitry may be a neurobiological signal representing intrinsic motivation for self-improvement that serves an adaptive function, increasing Chinese students’ motivation to engage in cognitive persistence.

Planning and Performance in Small Groups: Collective Implementation Intentions Enhance Group Goal Striving.

There are two key motivators to perform well in a group: making a contribution that (a) is crucial for the group (indispensability) and that (b) the other group members recognize (identifiability). We argue that indispensability promotes setting collective (“We”) goals whereas identifiability induces individual (“I”) goals. Although both goals may enhance performance, they should align with different strategies. Whereas pursuing collective goals should involve more cooperation, pursuing individual goals should involve less cooperation. Two experiments support this reasoning and show that planning out collective goals with collective implementation intentions (cIIs or “We-plans”) relies on cooperation but planning out individual goals with individual implementation intentions (IIs or “I-plans”) does not. In Experiment 1, three-member groups first formed a collective or an individual goal and then performed a first round of a physical persistence task. Groups then either formed a respective implementation intention (cII or II) or a control plan and then performed a second round of the task. Although groups with cIIs and IIs performed better on a physical persistence task than respective control groups, only cII groups interacted more cooperatively during task performance. To confirm the causal role of these interaction processes, Experiment 2 used the same persistence task and manipulated whether groups could communicate: When communication was hindered, groups with cIIs but not groups with IIs performed worse. Communication thus qualifies as a process making cIIs effective. The present research offers a psychology of action account to small group performance.

Implicit Theories About Willpower in Resisting Temptations and Emotion Control

Abstract. Previous research suggests that people’s implicit theories about willpower affect continuous self-control performance in the domain of strenuous mental activities. The present research expands these findings to two further domains of self-control: resisting temptations and emotion control. In Study 1, participants were either led to resist a temptation or not. Participants who believed that willpower gets depleted by resistance to temptations (limited-resource theory) performed significantly worse in a subsequent Stroop task compared to participants who believed that resisting temptations activates their willpower (nonlimited-resource theory). In Study 2, participants controlled their emotions during a funny video or were allowed to express them. Participants who believed that controlling emotions depletes willpower performed worse in a subsequent persistence task than those who believed that controlling emotions activates willpower. Results suggest that implicit theories about willpower are domain specific and sensitive to the domain of the initial self-control task rather than that of the subsequent self-control task.

Persistent illusory apparent motion in sequences of uncorrelated random dots.

We report a novel phenomenon in which long sequences of random dot arrays refreshing at 2.5 Hz lead to persistent illusory percepts of coherent apparent motion. We term this effect illusory apparent motion (IAM). To quantify this illusion, we devised a persistence task in which observers are primed with a particular motion pattern and must indicate when the motion pattern ends. In Experiment 1 (N = 119), we induced translational apparent motion patterns and show that both drifting motion (e.g., up-up-up-up) and rebounding motion (e.g., up-down-up-down) persists throughout many frames of uncorrelated random dots, although rebounding motion tends to persist for longer (a rebounding bias). In Experiment 2 (N = 60), we induced rotational IAM on an annulus-shaped display, and show that the topology of the display (whether the annulus is complete or has a gap) determines whether or not the rebounding bias is present. Based on our findings, we argue that IAM provides a powerful tool to study the mechanisms, constraints, and individual differences in the perception of illusory motion.

High monetary reward rates and caloric rewards decrease temporal persistence.

Temporal persistence refers to an individual's capacity to wait for future rewards, while forgoing possible alternatives. This requires a trade-off between the potential value of delayed rewards and opportunity costs, and is relevant to many real-world decisions, such as dieting. Theoretical models have previously suggested that high monetary reward rates, or positive energy balance, may result in decreased temporal persistence. In our study, 50 fasted participants engaged in a temporal persistence task, incentivised with monetary rewards. In alternating blocks of this task, rewards were delivered at delays drawn randomly from distributions with either a lower or higher maximum reward rate. During some blocks participants received either a caloric drink or water. We used survival analysis to estimate participants' probability of quitting conditional on the delay distribution and the consumed liquid. Participants had a higher probability of quitting in blocks with the higher reward rate. Furthermore, participants who consumed the caloric drink had a higher probability of quitting than those who consumed water. Our results support the predictions from the theoretical models, and importantly, suggest that both higher monetary reward rates and physiologically relevant rewards can decrease temporal persistence, which is a crucial determinant for survival in many species.

Multimodal examination of distress tolerance and posttraumatic stress disorder symptoms in acute-care psychiatric inpatients

Distress tolerance (DT), the actual or perceived capacity to withstand negative internal states, has received increasing scholarly attention due to its theoretical and clinical relevance to posttraumatic stress disorder (PTSD). Past studies have indicated that lower self-reported – but not behaviorally observed – DT is associated with greater PTSD symptoms; however, studies in racially and socioeconomically diverse clinical samples are lacking. The current study evaluated associations between multiple measures of DT (self-report and behavioral) and PTSD symptoms in an urban, racially and socioeconomically diverse, acute-care psychiatric inpatient sample. It was hypothesized that lower self-reported DT (Distress Tolerance Scale [DTS]), but not behavioral DT (breath-holding task [BH]; mirror-tracing persistence task [MT]), would be associated with greater PTSD symptoms, above and beyond the variance contributed by trauma load, substance use, gender, race/ethnicity, and subjective social status. Participants were 103 (41.7% women, Mage=33.5) acute-care psychiatric inpatients who endorsed exposure to potentially traumatic events consistent with DSM-5 PTSD Criterion A. Results of hierarchical regression analyses indicated that DTS was negatively associated with PTSD symptom severity (PCL-5 Total) as well as with each of the four DSM-5 PTSD symptom clusters (p’s<0.001), contributing between 5.0%–11.1% of unique variance in PTSD symptoms across models. BH duration was positively associated with PTSD arousal symptom severity (p<0.05). Covariates contributed between 21.3%–40.0% of significant variance to the models. Associations between DT and PTSD in this sample of acute-care psychiatric inpatients are largely consistent with those observed in community samples.

Frustration Tolerance in Youth With ADHD

Objective: The objective of this study was to compare children with ADHD with children without ADHD on frustration tolerance and to examine the role of oppositional defiant disorder (ODD) in frustration tolerance within the sample. Method: Participants included 67 children ages 10 to 14 years-old with (n = 37) and without (n = 30) Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) ADHD who completed the Mirror Tracing Persistence Task (MTPT), a validated computerized behavioral measure of frustration tolerance. Results: Children with ADHD were more likely to quit this task than children without ADHD, demonstrating lower levels of frustration tolerance. There were no differences in frustration tolerance between children with ADHD + ODD and those with ADHD – ODD. Moreover, ODD did not moderate the relationship between ADHD and frustration tolerance. Conclusion: Our results suggest that low frustration tolerance is directly linked to ADHD and not better accounted for by ODD. This research highlights specific behavioral correlates of frustration in children with ADHD.

(530) Distress intolerance and prescription opioid misuse among patients with chronic pain

A substantial proportion of chronic pain patients who are on long-term opioid therapy will misuse their medication, leading to a variety of adverse events and consequences. Understanding the risk factors for developing opioid misuse behaviors is crucial for intervention and prevention of future cases. Distress intolerance is an important vulnerability factor in substance use disorders, but has not been widely investigated in chronic pain. The primary aim of this study was to examine whether distress intolerance was associated with opioid misuse among individuals with chronic pain receiving long-term opioid treatment. After completing questionnaires, participants underwent Quantitative Sensory Testing (including mechanical pain thresholds, mechanical temporal summation, and repeated cold pressor tasks) and the Computerized Mirror Tracing Persistence Task (MTPT) in a randomized order. Distress intolerance was measured behaviorally using the MTPT and a self-report Distress Intolerance Index (DII). Opioid misuse was assessed by the Current Opioid Misuse Measure (COMM) and the Addiction Behaviors Checklist. The DII and MTPT were modestly, but significantly correlated (r = -0.31, p = .03). There was a significant association between the DII and both opioid misuse status (p= .04), and COMM scores (r = .52, p < .001), suggesting that higher levels of distress intolerance were associated with more frequent and more severe opioid misuse. The DII was modestly associated with elevated pain rating during the cold pressor test (p = .03), and with anxiety ratings during psychophysical testing. These findings highlight the relevance of distress intolerance in shaping opioid misuse behaviors. Collectively, enhancing our ability to identify patients at greater risk for opioid misuse would allow for closer monitoring of this subgroup, and may provide targets for intervention to reduce medication misuse.

The prospective effects of perceived and laboratory indices of distress tolerance on cannabis use following a self-guided quit attempt.

The majority of individuals who attempt to quit using cannabis do not seek formalized treatment. To better understand which malleable factors contribute to cannabis use following a self-guided quit attempt, we concurrently examined 2 measures of distress tolerance (DT) as prospective predictors of cannabis use post quit attempt. We hypothesized that veterans with higher in relation to lower levels of DT would be less likely to use cannabis following a self-guided quit attempt. In this study, we included 103 cannabis-dependent veterans (Mage = 50, 95% male, 37% White, 36% Black, 14% Hispanic, 14% other) who reported being motivated to quit using cannabis. Veterans completed 2 measures of DT, the Distress Tolerance Scale (perceived distress tolerance) and the Mirror-Tracing Persistence Task (laboratory analogue of distress tolerance). Findings indicated that veterans with greater perceived distress tolerance used less cannabis over the quit period than did veterans with less perceived distress tolerance. However, contrary to expectations, baseline performance on a laboratory analogue of distress tolerance was not related to cannabis use over the quit period. Results suggest that veterans' perceived ability to tolerate distress is an important predictor of cannabis use following a self-guided quit attempt. Thus, the Distress Tolerance Scale could serve as an important tool for helping to identify veterans at risk for cannabis use postquit.

A Test of Learned Industriousness in the Physical Activity Domain.

The Theory of Learned Industriousness states that durable individual differences in industriousness are due in part to differences in the extent to which individuals were rewarded for high effort at an earlier time. Individuals rewarded for high effort during training are thought to generalize greater persistence to subsequent tasks than those rewarded for low effort. This study tested whether rewarded physical and/or mental effort at different intensities generalized to greater persistence at a subsequent mental task. 80 inactive 18-25 year-olds were randomized into four groups: Low Mental Effort, High Mental Effort, Low Physical Effort, and High Physical Effort. Each completed group-specific effort training and a mental persistence task at baseline and posttest. Factorial analysis of covariance revealed a significant domain x effort interaction on persistence (F[1,75]=4.93, p=.029). High Mental Effort and Low Mental Effort groups demonstrated similar gains in persistence (d=-0.08, p>.05) and points earned (d=0.11, p>.05) following effort training. High Physical Effort and Low Physical Effort diverged on persistence (d=-0.49, p=.004) but not points earned (d =-0.12, p>.05). Findings suggest either that training and test stimuli were too dissimilar to cue effects of associative learning in physical effort groups, or that effects were present but overpowered by the affective and neurocognitive consequences of an acute bout of intense aerobic physical activity. Findings do not support the Theory of Learned Industriousness nor generalization of effort across physical and mental domains.

Social support from fellow group members triggers additional effort in groups

AbstractThis research demonstrates social support from fellow group members as unique trigger of additional effort and performance in groups. Support‐induced effort gains are shown both compared with groups without social support and individual work. Study 1 examined existing beliefs about motivating group work among employees with professional group work experience (n = 130). The results revealed social support as one of the most frequently reported sources of group‐induced effort gains. Study 2 explored self‐reported effort intentions in group training scenarios among athletes (n = 94). Finally, Study 3 examined performance as a manifest indicator of effort in an experimental persistence task among students (n = 88). The results of Study 2 and Study 3 showed significant gains due to social support in both self‐reported effort and manifest performance, respectively. Together, the results demonstrate that receiving social support from fellow group members leads to higher effort in groups at the level of existing beliefs about motivating group work, at the level of effort intentions, and at the level of manifest performance behavior. The observed findings cannot be explained by established sources of motivation gains in groups such as social comparison or social indispensability. Copyright © 2014 John Wiley &amp; Sons, Ltd.

Validation of Self-Report Measures of Emotional and Physical Distress Tolerance

The Distress Tolerance Scale (DTS) and Discomfort Intolerance Scale (DIS) are self-report measures developed for the assessment of emotional and physical distress tolerance, respectively. However, little evidence exists for their construct and specifically criterion-related validity. The current study examined the associations of these self-report measures with lab-based assessments of perceived emotional tolerance and physical discomfort tolerance. Undergraduate participants (N = 166) were administered four film clips intended to induce sadness, disgust, fear, and anger, and a handgrip persistence task intended to elicit physical discomfort. The DTS, but not the DIS, was significantly associated with self-reported emotional tolerance and perceived threat associated with each film after controlling for emotional intensity. Among DTS subscales, the absorption subscale was the only subscale incrementally predictive of negative perceptions of the sad film, the appraisal subscale was incrementally predictive of negative perceptions of the other three films, and little support for the incremental validity of the tolerance and regulation subscales was found. The DTS also incrementally predicted tolerance and perceived threat of film-elicited emotions across films after controlling for anxiety sensitivity. The DIS was only marginally predictive of handgrip task persistence and was unrelated to emotional film perceptions. Overall, these findings uniquely add to the empirical literature on the construct and criterion-related validity of the DTS and DIS.

The Roles of Emotional Reactivity and Tolerance in Generalized, Social, and Health Anxiety: A Multimethod Exploration

Emotion regulation difficulties have been implicated in the maintenance of many anxiety disorders. However, existing research has relied mostly on self-report measures of emotion regulation or one type of mood induction. The present study examined the relationships between anxiety symptoms and emotional reactivity and tolerance using multiple assessment methodologies. Participants (N=122) completed measures of generalized, social, and health anxiety symptoms and reported tolerance of and reactivity to negative emotions (sadness, fear, anger, disgust) elicited by 4 film clips. Participants also completed a mirror-tracing persistence task, a behavioral measure of distress tolerance. Social anxiety symptoms predicted unique variance in tolerance of film-elicited emotions, whereas generalized anxiety symptoms predicted unique variance in total peak reactivity to film-elicited emotions. Health anxiety was not related to tolerance or peak reactivity, but it was predictive of greater anxiety following the mirror-tracing task. The results of this study suggest heightened emotional reactivity is a salient feature of generalized anxiety symptoms, whereas emotional tolerance is more strongly related to social anxiety symptoms. The unique association between health anxiety and anxious response to the distress tolerance task represents a novel finding that warrants further investigation.

“… with a little help from my friends”: friendship, effort norms, and group motivation gain

PurposeThe purpose of this paper is to report on new research that explores the effect of co‐worker friendship and performance norms on the Köhler motivation gain effect.Design/methodology/approachFemales worked at a motor persistence task with either a more capable coactor or with a more capable team‐mate (where the group's task had conjunctive task demands; i.e. the performance of the weaker team‐mate defined the group's score). The co‐workers (coactors or team‐mates) were either friends or strangers. Participants were also led to believe that their co‐workers and peers endorsed social norms prescribing either high or low level of effort at the task.FindingsCompared to comparable individual control workers, the inferior‐ability coactors showed a significant motivation gain (attributable to social‐comparison processes); this gain was not moderated by either friendship or performance norms. Inferior‐ability members of the collaborative teams worked significantly harder than the coactors (attributable to the indispensability of their efforts under these work conditions), but only when their partners were friends or the performance norms prescribed high effort.Research limitations/implicationsThe research focuses on short‐term laboratory groups of females working together for a very brief period. The applicability of the findings to more typical work teams will require further research.Practical implicationsThe research suggests that the task motivation of particular team members (namely, those with the least ability) can be increased by strengthening social ties between team‐mates and promoting high effort social norms.Originality/valueThe research adds to a growing literature that identifies when and why members of work groups will work harder than comparable individual workers.

Interrelating Behavioral Measures of Distress Tolerance with Self-Reported Experiential Avoidance

Experiential avoidance and distress intolerance play a central role in novel behavior therapies, yet they appear to overlap considerably the REBT concept of low frustration tolerance. Using baseline data from 100 adult cigarette smokers enrolled in a clinical trial of smoking cessation therapies, the present study evaluated the convergent validity of common questionnaire measures of experiential avoidance (Acceptance and Action Questionnaire; AAQ; Hayes et al. 2004, and Avoidance and Inflexibility Scale: AIS; Gifford et al. 2004) and behavioral measures of distress tolerance (computerized Mirror Tracing Persistence Task: MTPT-C: Strong et al. 2003; computerized Paced Auditory Serial Addition Task; PASAT-C; Lejuez et al. 2003). The distress tolerance measures correlated significantly (r = .29) with one another. However, the questionnaire measures of experiential avoidance did not correlate with each other, nor with the behavioral measures. Further research is needed on the validity of measuring experiential avoidance by self-report and of the overlap versus distinctiveness of seemingly similar constructs such as experiential avoidance, distress tolerance, and frustration tolerance.
