Itch is a prevalent somatosensory symptom thatcan be highly disabling , because it is likely to drawattention and, as a resu lt, may interfere with the perfor-mance of daily activities. Yet, research experimentallyinvestigating attention to itch is lacking. In this study weaimed to investigate attentional processing of itch usingmultiple behavioral attention tasks. Forty-one healthyparticipants performed (1) a modified Stroop task with itch-related words, (2) a dot-probe task with itch-related pic-tures, and (3) a rece ntly developed somatosensory attentiontask in which the effect of experimentally induced itch onthe localization of visual targets was examined. Addition-ally, a number of self-report questionnaires related tosomatosensory attentional processing were administered.Results indicated that participants’ attention was biasedtoward itch-related words and pictures assessed by meansof the dot- probe and modified Stroop task, respectively. Forthe somatosensory attention task, results showed that itchdid not significantly influence the allocation of attention.However, when taking into account the time course ofattention during the itch stimulus, data suggested thatparticipants tended to disengage attention away during theitch stimulus. This is the first study that indicates anattentional bias for itch, using methods that have previouslybeen validated for other sensations such as pain. In addi-tion, the newly developed somatosensory attention taskmay reflect the time course of attention toward a tonic itchstimulus. [less ▲]

Objective: The factors underlying the aetiology of fibromyalgia (FM) are largely unknown. According to the generalized hypervigilance hypothesis (GHH), FM patients show excessive attention towards pain stimuli and other sensory events, thereby increasing pain perception and dysfunctional behaviour. We tested this notion by assessing interoceptive accuracy (IA) in FM patients and matched healthy controls. We also tested the hypothesis that FM is characterized by reduced self-regulatory capacity as indexed by heart rate variability (HRV). Methods: 47 FM patients (Mage = 45.5, 39 females) and 45 healthy controls (Mage = 44.9, 37 females) completed several self-report scales (Body Vigilance Scale, Depression Anxiety Stress Scales, Pain Catastrophizing Scale). To derive HRV, heart rate was monitored under resting conditions; for the assessment of IA participants performed a heartbeat tracking task in which they were asked to silently count their heartbeats. Results: FM patients reported higher body vigilance than healthy controls, but there were no group differences in IA. FM patients had lower HRV compared with healthy controls. HRV did not predictor IA. Conclusion: In conclusion, our findings do not support the hypothesis of generalized hypervigilance in FM patients. Patients reported a heightened focus on bodily sensations, which was not reflected in IA. It may be that hypervigilance is not a general and stable characteristic but is rather context dependent and modality-specific. [less ▲]

The Levels of Emotional Awareness Scale for Children (LEAS-C) is a performance-based instrument that assesses emotional awareness in the structure of written responses to a set of real-life scenarios. While it is theoretically expected that emotional awareness develops with age, virtually no age differences have been established with the LEAS-C. The present study investigated whether an adaptation of the instructions and scoring procedure on the basis of the componential emotion approach could improve the validity of the LEAS-C and reveal the theoretically expected age differences. An adapted LEAS-C was administered to a sample of 574 children and adolescents and scored with the original and a new componential scoring procedure. An acceptable reliability for the original and a good reliability and a high interrater reliability for the componential scoring procedure were observed. Multigroup confirmatory factor analyses showed measurement invariance of factor loadings and intercepts across children (8 to 12 years) and adolescents (13 to 16 years) for all tested models, for both scoring procedures. A one-factor model fitted well for the total scores and self and other scores for both scoring procedures. The pattern of relationships with alexithymia, emotional intelligence, intelligence, personality, and social and emotional impairment as well as gender differences were comparable with prior research. Furthermore, the expected relationship with age was found, with stronger correlations for the componential than the original scoring procedure. In conclusion, analyses of the reliability, internal structure, and nomological network supported the adaptations of the LEAS-C on the basis of the componential emotion approach.

The current study examined the relationship between perceived injustice and attentional bias (AB) toward pain among individuals with chronic low back pain asked to perform and appraise the pain and difficulty of a standardized set of common physical activities. A pictorial dot-probe task assessed AB toward pain stimuli (ie, pain faces cueing pain), after which participants performed the physical tasks. Participants also rated face stimuli in terms of pain, sadness, and anger expression. As hypothesized, perceived injustice was positively associated with AB toward pain stimuli; additionally, perceived injustice and AB were positively associated with appraisals of pain and difficulty. Counter to expectations, AB did not mediate the relationship between perceived injustice and task appraisals, suggesting that AB is insufficient to explain this relationship. Exploratory analyses indicated that participants with higher levels of perceived injustice rated stimulus faces as sadder and angrier; no such differences emerged for pain ratings. To our knowledge, this is the first study to examine the association between perceived injustice and AB toward pain, as well as perceived injustice and in vivo appraisals of common physical activity. Results extend existing literature and suggest that attentional and potential interpretive bias should be considered in future research. PERSPECTIVE: This article identifies significant associations between perceived injustice, biased attention to pain, and appraisals of common physical activities among individuals with chronic low back pain. These findings suggest targets for intervention as well as directions for future research regarding individuals with high perceptions of injustice related to pain. [less ▲]

OBJECTIVE: Serious games may be effective in promoting sexual health behavior. Their confidential nature may encourage users to discuss sensitive sexuality topics. Furthermore, they can tailor messages to the individual's needs and may be intrinsically motivating. This meta-analysis investigates the effectiveness of interventions for sexual health promotion that use serious games. MATERIALS AND METHODS: A database search was conducted in PubMed, Web of Science, CINAHL, and PsycINFO for publications before the end of July 2013. Serious digital games studies measuring effects on behavior or its determinants, using a control condition, allowing the calculation of an effect size (Hedges' g, random-effects model) were included. RESULTS: Seven game studies for sexual health promotion were included. These showed positive effects on determinants (g=0.242; 95 percent confidence interval, 0.129, 0.356), albeit of small effect size. The effects on behavior, measured in only two studies, were not significant (g=0.456; 95 percent confidence interval, -0.649, 1.561). Most games did not use many game features that are considered to be immersive or enhancing flow. Instead, there was a strong reliance on pure gamification features, such as rewards and feedback. CONCLUSIONS: The effectiveness of the next generation of games may be enhanced by building on the behavioral change and educational gaming literatures (e.g., using role-play and simulation game formats, individual tailoring, offering adaptation in the difficulty of the challenge, and amount and timing of the feedback). There is a need for studies with rigorous evaluations of game effectiveness, longer-term follow-up, and using measures of behavior rather than merely their determinants. [less ▲]

This study considered the attentional functioning of adolescents with varying levels of pain catastrophizing. Specifically, we investigated the relationship between pain catastrophizing and attention bias to pain facial expressions. Furthermore, drawing on dual process models in the context of pain, we investigated the moderating role of attention control on this relationship. Adolescents (N = 73; age, 16-18 years) performed a dot-probe task in which facial expressions of pain and neutral expressions were presented for 100 milliseconds and 1250 milliseconds. Participants also completed self-report pain catastrophizing and attention control measures. We found that although there was no main effect of pain catastrophizing on attention bias towards pain faces, attention control did significantly moderate this relationship. Further analysis revealed that lower levels of attention control were significantly associated with increasing attentional vigilance towards pain faces only within high catastrophizing adolescents. In addition, we found that poorer attention control was related to increased attention bias for pain faces (regardless of pain catastrophizing level) when these faces were presented for relatively longer durations (ie, 1250 milliseconds) but not for short durations (ie, 100 milliseconds). This study supports a dual process model of attentional processes in pain, thus replicating previous findings within the psychopathology literature but extending them to the study of pain. Theoretical and clinical implications of our findings are discussed. [less ▲]

Patients with chronic pain often report their cognition to be impaired by pain, and this observation has been supported by numerous studies measuring the effects of pain on cognitive task performance. Furthermore, cognitive intrusion by pain has been identified as one of 3 components of pain anxiety, alongside general distress and fear of pain. Although cognitive intrusion is a critical characteristic of pain, no specific measure designed to capture its effects exists. In 3 studies, we describe the initial development and validation of a new measure of pain interruption: the Experience of Cognitive Intrusion of Pain (ECIP) scale. In study 1, the ECIP scale was administered to a general population sample to assess its structure and construct validity. In study 2, the factor structure of the ECIP scale was confirmed in a large general population sample experiencing no pain, acute pain, or chronic pain. In study 3, we examined the predictive value of the ECIP scale in pain-related disability in fibromyalgia patients. The ECIP scale scores followed a normal distribution with good variance in a general population sample. The scale had high internal reliability and a clear 1-component structure. It differentiated between chronic pain and control groups, and it was a significant predictor of pain-related disability over and above pain intensity. Repairing attentional interruption from pain may become a novel target for pain management interventions, both pharmacologic and nonpharmacologic. [less ▲]

Several systematic reviews have described health-promoting effects of serious games but so far no meta-analysis has been reported. This paper presents a meta-analysis of 54 serious digital game studies for healthy lifestyle promotion, in which we investigated the overall effectiveness of serious digital games on healthy lifestyle promotion outcomes and the role of theoretically and clinically important moderators. Findings showed that serious games have small positive effects on healthy lifestyles (g=0.260, 95% CI 0.148; 0.373) and their determinants (g=0.334, 95% CI 0.260; 0.407), especially for knowledge. Effects on clinical outcomes were significant, but much smaller (g=0.079, 95% CI 0.038; 0.120). Long-term effects were maintained for all outcomes except for behavior. Serious games are best individually tailored to both socio-demographic and change need information, and benefit from a strong focus on game theories or a dual theoretical foundation in both behavioral prediction and game theories. They can be effective either as a stand-alone or multi-component programs, and appeal to populations regardless of age and gender. Given that effects of games remain heterogeneous, further explorations of which game features create larger effects are needed. [less ▲]

This meta-analysis investigated whether attentional bias, that is, the preferential allocation of attention to information that is related to pain, is a ubiquitous phenomenon. We also investigated whether attentional bias effects are related to the methodological quality of the study, to procedural differences in their measurement, or to individual differences in pain severity, pain-related fear, anxiety, and depression. Results indicated that individuals who experience chronic pain (n=1023) display an attentional bias towards pain-related words or pictures, but this bias was of a small effect size (d=0.134), and did not differ from that in control groups (d=0.082; n=1398). No evidence was found for an attentional bias towards pain-related words and pictures for acute pain (d=0.049), procedural pain (d=0.142), and experimental pain (d=0.069). However, research in which attentional bias towards signals of impending experimental pain in healthy volunteers was investigated, revealed an attentional bias of medium effect size (d=0.676). Moderator analyses in the chronic pain group identified important procedural variables that affected the presence and magnitude of an attentional bias towards pain-related words and pictures, that is, type and exposure time of pain-related information. None of the individual difference variables affected the magnitude of the attentional bias. Implications of current findings and future directions are discussed. [less ▲]

Theoretical accounts of chronic pain hypothesize that attentional bias towards pain-related information is a maintaining or exacerbating factor, fuelling further pain, disability, and distress. However, empirical research testing this idea is currently lacking. In the present study, we investigated whether attentional bias towards pain-related information predicts daily pain-related outcomes in a sample of chronic pain patients (n=69; M(age)=49.64 years; 46 females). During an initial laboratory session, attentional bias to pain-related information was assessed using a modified spatial cueing task. In advance, patients completed a number of self-report measures assessing current pain intensity, current disability, and pain duration. Subsequently, daily pain outcomes (self-reported pain severity, disability, avoidance behaviour, and distractibility) were measured for 2 weeks by means of an electronic diary. Results indicated that, although an attentional bias towards pain-related information was associated with the current level of disability and pain severity, it had no additional value above control variables in predicting daily pain severity, avoidance, distractibility, and disability. Attentional bias towards pain-related information did, however, moderate the relationship between daily pain severity and both daily disability and distractibility, indicating that, particularly in those patients with a strong attentional bias, increases in pain were associated with increased disability and distractibility. The use of interventions that diminish attentional bias may therefore be helpful to reduce daily disability and the level of distraction from current tasks despite the presence of pain in chronic pain patients.

OBJECTIVE: This study aimed at developing an experimental paradigm to assess vicarious pain experiences. We further explored the putative moderating role of observer's characteristics such as hypervigilance for pain and dispositional empathy. METHODS: Two experiments are reported using a similar procedure. Undergraduate students were selected based upon whether they reported vicarious pain in daily life, and categorized into a pain responder group or a comparison group. Participants were presented a series of videos showing hands being pricked whilst receiving occasionally pricking (electrocutaneous) stimuli themselves. In congruent trials, pricking and visual stimuli were applied to the same spatial location. In incongruent trials, pricking and visual stimuli were in the opposite spatial location. Participants were required to report on which location they felt a pricking sensation. Of primary interest was the effect of viewing another in pain upon vicarious pain errors, i.e., the number of trials in which an illusionary sensation was reported. Furthermore, we explored the effect of individual differences in hypervigilance to pain, dispositional empathy and the rubber hand illusion (RHI) upon vicarious pain errors. RESULTS: RESULTS of both experiments indicated that the number of vicarious pain errors was overall low. In line with expectations, the number of vicarious pain errors was higher in the pain responder group than in the comparison group. Self-reported hypervigilance for pain lowered the probability of reporting vicarious pain errors in the pain responder group, but dispositional empathy and the RHI did not. CONCLUSION: Our paradigm allows measuring vicarious pain experiences in students. However, the prevalence of vicarious experiences of pain is low, and only a small percentage of participants display the phenomenon. It remains however unknown which variables affect its occurrence.

The present study investigated selective attention to pain in children, its implications for child avoidance behaviour, and the moderating role of dimensions comprising child and parental catastrophizing about pain (ie, rumination, magnification, and helplessness). Participants were 59 children (31 boys) aged 10-16 years and one of their parents (41 mothers). Children performed a dot-probe task in which child facial pain displays of varying pain expressiveness were presented. Child avoidance behaviour was indexed by child pain tolerance during a cold-pressor task. Children and parents completed measures of child and parent pain catastrophizing, respectively. Findings indicated that both the nature of child selective attention to pain and the impact of selective attention upon child avoidance behaviour were differentially sensitive to specific dimensions of child and parental catastrophizing. Specifically, findings showed greater tendency to shift attention away from pain faces (i.e.,, attentional avoidance) among children reporting greater pain magnification. A similar pattern was observed in terms of parental characteristics, such that children increasingly shifted attention away from pain with increasing levels of parental rumination and helplessness. Furthermore, child attentional avoidance was associated with greater avoidance behaviour (i.e., lower pain tolerance) among children reporting high levels of pain magnification and those whose parents reported greater rumination about pain. The current findings corroborate catastrophizing as a multidimensional construct that may differentially impact outcomes and attest to the importance of assessing both child and parental characteristics in relation to child pain-related attention and avoidance behaviour. Further research directions are discussed. [less ▲]

Chronic pain often interferes with daily functioning, and may become a threat to an individual's sense of self. Despite the development of a recent theoretical account focussing upon the relationship between the presence of chronic pain and a person's self, research investigating this idea is limited. In the present study we aimed to (1) compare the strength of association between self- and pain schema in patients with chronic pain and healthy control subjects and (2) research whether the strength of association between self- and pain-schema is related to particular pain-related outcomes and individual differences of patients with chronic pain. Seventy-three patients with chronic pain (M(age) = 49.95; SD = 9.76) and 53 healthy volunteers (M(age) = 48.53; SD = 10.37) performed an Implicit Association Test (IAT) to assess the strength of association between pain- and self-schema. Patients with chronic pain also filled out self-report measures of pain severity, pain suffering, disability, depression, anxiety, acceptance, and helplessness. Results indicated that the pain- and self-schema were more strongly associated in patients with chronic pain than in healthy control subjects. Second, results indicated that, in patients with chronic pain, a stronger association between self- and pain-schema, as measured with the IAT, is related to a heightened level of pain severity, pain suffering, anxiety, and helplessness. Current findings give first support for the use of an IAT to investigate the strength of association between self- and pain-schema in patients with chronic pain and suggest that pain therapies may incorporate techniques that intervene on the level of self-pain enmeshment.
