The exploration-exploitation dilemma in pain: an experimental investigation.

Angelos-Miltiadis Krypotos, Geert Crombez, Maryna Alves, Nathalie Claes, Johan W S Vlaeyen,

<h4>Abstract</h4>Daily life consists of a chain of decisions. Typically, individuals may choose to pursue what they already know (exploitation), or to search for other options (exploration). This exploration-exploitation dilemma is a topic of interest across multiple scientific fields. Here we propose that investigating how individuals solve this dilemma may improve ... Read more >>

<h4>Purpose</h4>Neuropathic pain is a common disorder of the somatosensory system that affects 7%-10% of the general population. The disorder places a large social and economic burden on patients as well as healthcare services. However, not everyone with a relevant underlying aetiology develops corresponding pain. DOLORisk Dundee, a European Union-funded cohort, ... Read more >>

When pain becomes uncontrollable: an experimental analysis of the impact of instructions on pain-control attempts.

Ama Kissi, Sean Hughes, Dimitri Van Ryckeghem, Jan De Houwer, Geert Crombez,

<h4>Abstract</h4>Under some conditions, people persist in their attempts to control their pain even when no such control is possible. Theory suggests that such pain-control attempts arise from actual pain experiences. Across 3 experiments we examined how (1) losing control over pain and (2) instructions concerning pain, moderated pain-control attempts. In ... Read more >>

Relationship between psychological factors and spinal motor behaviour in low back pain: a systematic review and meta-analysis.

Guillaume Christe, Geert Crombez, Shannon Edd, Emmanuelle Opsommer, Brigitte M Jolles, Julien Favre,

<h4>Abstract</h4>This meta-analysis investigated whether more negative psychological factors are associated with less spinal amplitude of movement and higher trunk muscle activity in individuals with low back pain. Furthermore, it examined whether pain intensity was a confounding factor in this relationship. We included studies that provided at least 1 correlation coefficient ... Read more >>

Altered regulation of negative affect in patients with fibromyalgia: A diary study.

Silke Rost, Geert Crombez, Stefan Sütterlin, Claus Vögele, Elke Veirman, Dimitri M L Van Ryckeghem,

<h4>Background</h4>Fibromyalgia is characterized by widespread musculoskeletal pain and often accompanied by cognitive and emotional problems. Adaptation to fibromyalgia may therefore also rely on one's ability to regulate emotional problems. In this study, we examined two indices of emotion regulation, that is, (a) affective instability, involving frequent large fluctuations in self-reported ... Read more >>

Decomposing conditioned avoidance performance with computational models

Angelos-Miltiadis Krypotos, Geert Crombez, Ann Meulders, Nathalie Claes, Johan Vlaeyen,

<p>Avoidance towards innocuous stimuli is a key characteristic across anxiety-related disorders and chronic pain. Insights into the relevant learning processes of avoidance are often gained via laboratory procedures, where individuals learn to avoid stimuli or movements that have been previously associated with an aversive stimulus. Typically, statistical analyses of data ... Read more >>

Self-compassion predicting pain, depression and anger in people suffering from chronic pain: A prospective study.

Anja Carina Emmerich, Thilo Friehs, Geert Crombez, Julia Anna Glombiewski,

Self-compassion is associated with disability, pain-related anxiety as well as depression and anger in patients with chronic pain. However, the unique value of self-compassion versus other concepts such as psychological flexibility and self-esteem is unknown. The present study therefore aimed to clarify these relationships. Individuals with chronic pain (N<sub>CP</sub> = 872) and ... Read more >>

Neuroticism may not reflect emotional variability.

Elise K Kalokerinos, Sean C Murphy, Peter Koval, Natasha H Bailen, Geert Crombez, Tom Hollenstein, John Gleeson, Renee J Thompson, Dimitri M L Van Ryckeghem, Peter Kuppens, Brock Bastian,

Neuroticism is one of the major traits describing human personality, and a predictor of mental and physical disorders with profound public health significance. Individual differences in emotional variability are thought to reflect the core of neuroticism. However, the empirical relation between emotional variability and neuroticism may be partially the result ... Read more >>

Laura Maenhout, Carmen Peuters, Greet Cardon, Sofie Compernolle New, Geert Crombez, Ann DeSmet,

<h4>Background: </h4> Healthy lifestyles may contribute to better mental health, which is particularly important in adolescence, an age at which half of all mental health problems first occur.

An investigation of perceptual biases in complex regional pain syndrome.

Annick L De Paepe, Valéry Legrain, Lien Van der Biest, Nadine Hollevoet, Alexander Van Tongel, Lieven De Wilde, Herlinde Jacobs, Geert Crombez,

Patients with complex regional pain syndrome (CRPS) report cognitive difficulties, affecting the ability to represent, perceive and use their affected limb. Moseley, Gallace & Spence (2009) observed that CRPS patients tend to bias the perception of tactile stimulation away from the pathological limb. Interestingly, this bias was reversed when CRPS ...

Let's talk about pain catastrophizing measures: an item content analysis.

Geert Crombez, Annick L De Paepe, Elke Veirman, Christopher Eccleston, Gregory Verleysen, Dimitri M L Van Ryckeghem,

Background:Concerns have been raised about whether self-report measures of pain catastrophizing reflect the construct as defined in the cognitive-behavioral literature. We investigated the content of these self-report measures; that is, whether items assess the construct 'pain catastrophizing' and not other theoretical constructs (i.e., related constructs or pain outcomes) using the ...

Evaluating the efficacy of an attention modification program for patients with fibromyalgia: a randomized controlled trial.

R Nicholas Carleton, Gordon J G Asmundson, Stephanie L Korol, Daniel M LeBouthillier, Kadie Hozempa, Joel D Katz, Johan W S Vlaeyen, Geert Crombez,

Persons with chronic musculoskeletal pain may be hypervigilant for pain-related cues which, paradoxically, may be maintaining their pain. Several randomized controlled trials have assessed whether a modified dot-probe protocol (ie, attention bias modification [ABM]) reduces chronic pain- and pain-related symptoms in persons with several diagnoses, including fibromyalgia. Scalability and economic ... Read more >>
