RESUMEN
BACKGROUND AND OBJECTIVES: Amongst social contextual influences on pain, the manner in which pain and painful procedures are communicated to patients is considered an important contributor to the subjective experience of pain. Threatening information, e.g., by the use of technical language, is suggested to increase pain reports. Validation, or communicating understanding towards another person reporting personal experiences, is suggested to reduce pain. The current study examines effects of both information language (technical vs. plain language) and validation (validation vs. invalidation) on the subjective experience of experimentally induced pain. METHODS: Pain-free participants (Nâ¯=â¯132) were randomly assigned to one of four groups as formed by manipulations of validation and information language. After reading a description concerning the upcoming thermal stimulus formulated in technical or plain language, participants engaged in a computer controlled simulation (CCS; based on virtual reality technology). Participants received three thermal stimuli while interacting with an avatar who either validated or invalidated their experience during the CCS. Pain intensity and pain unpleasantness were assessed after each stimulus. RESULTS: The validation manipulation showed to be effective, but the information language manipulation did not induce differential threat expectancies. Results show no effect of validation or information language on subjective pain reports. LIMITATIONS: Suboptimality of the information language manipulation and shortcomings of the CCS procedure might account for current findings. CONCLUSIONS: The study offers an interesting model for the further experimental study of isolated and combined effects of (social) contextual factors on pain. Diverse future research avenues are discussed.

OBJECTIVE: Painful diabetic neuropathy (PDN) is known to negatively affect quality of life. Being physically active is a crucial part of successful diabetes self-management, but regimen adherence is often low. Coping strategies and fears have shown to be related to less physical activity (PA). The aim of the present study was to obtain more in-depth information on psychological risk factors leading to less PA in persons with PDN. DESIGN: Three semi-structured focus group interviews were conducted with a representative sample of persons with PDN (N = 12). Data were transcribed verbatim and analysed using a hybrid method of thematic analyses and a grounded theory approach. MAIN OUTCOME MEASURES: Fears and coping strategies related to PA in persons with PDN. RESULTS: Several specific fears were identified; fear of hypoglycaemia, fear of pain increase, fear of total exhaustion, fear of physical injury, fear of falling, fear of loss of identity, and fear of negative evaluation by others. To cope with these fears, avoidance, remaining active, cognitive distraction, and acceptance strategies were described. CONCLUSION: In persons with PDN, diabetes-related fears and pain-related fears play a role in less engagement in PA, indicating the need for new methods for improving self-management in persons with PDN.

In chronic low back pain (CLBP) research, the self-discrepancy model has been applied to explain dysfunctional avoidance and persistence behaviour. The main aim of this study was to evaluate whether specific self-discrepancies in patients with CLBP are associated with the abovementioned types of activity-related behaviour and whether changes in self-discrepancies over time are associated with changes in activity-related behaviour. Furthermore, the aim was to evaluate whether avoidance and persistence behaviour are associated with a higher level of disability and a diminished quality of life and whether changes over time in avoidance and persistence behaviour result in changes in disability and quality of life. A longitudinal cohort study in a sample of patients with CLBP (N=116), in which self-discrepancies, disability, quality of life, and objectively registered characteristics of activity-related behaviour were measured, was performed to evaluate the pathways in the aforementioned self-discrepancy model. Results indicate that patients with CLBP who feel closer to their ideal-other show more characteristics of persistence behaviour. Patients who move further away from their ideal-own also show more characteristics of persistence behaviour. Furthermore, in patients characterized as avoider, a decrease in a patient's daily uptime was associated with a decrease of mental health-related quality of life.

UNLABELLED: Activity patterns are believed to play an important role in the development and perpetuation of chronic pain. So far, 3 important activity patterns have been studied: avoidance behavior, persistence behavior, and pacing behavior. Yet, empirical evidence is limited and inconclusive about the relationships between these activity patterns and important outcomes. Therefore, the present study was aimed at identifying activity patterns by means of factor analyses and determining their relationship with disability and depressive symptomatology in participants with chronic pain (N = 132). Items across different measurement instruments pertaining to 1 particular activity pattern were aggregated, and submitted to factor analysis. Results from 3 separate factor analyses revealed 6 distinct activity patterns: pain avoidance, activity avoidance, task-contingent persistence, excessive persistence, pain-contingent persistence, and pacing. In line with our hypotheses, pain and activity avoidance, and excessive persistence, were related to higher levels of disability and depressive symptomatology. In contrast to hypotheses, pacing was associated with worse outcomes as well. Interestingly, task-contingent persistence was related to lower levels of disability and depressive symptomatology. When controlling for pain and the other activity patterns, excessive persistence and activity avoidance were the most detrimental in terms of relations with depressed mood or disability. Task-contingent persistence appeared to be the least detrimental. PERSPECTIVE: Our findings suggest the existence of several activity patterns, which are differentially related to disability and depressive symptomatology, in participants with chronic pain. The present results are discussed in the light of previous findings, and may provide a new impetus for future studies on activity patterns in chronic pain research.

Chronic pain not only interferes with daily activities, it may also have a negative impact on the perceived integrity of one's self through self-discrepancies. Self-discrepancies are experienced distances between the actual self and self-guides that can exist from 2 perspectives (ie, own and other). Self-discrepancies are associated with negative mood states and incite self-regulatory behavior in order to reduce these discrepancies. The present study was aimed at replicating the emotional consequences of self-discrepancies in patients with chronic low back pain, and extending current knowledge of the behavioral consequences of self-discrepancies (ie, behavioral activity patterns such as avoidance and persistence). A cross-sectional design was employed with 83 patients who completed a number of self-report measures. We hypothesized that ideal and ought discrepancies, as well as feared congruencies were associated with depressed and anxious mood. On the behavioral level, a U-shaped relationship was hypothesized between ideal and ought self-discrepancies and persistence behavior, whereas feared self-discrepancies were hypothesized to be related to avoidance behavior. Results were partially in line with the hypotheses. With respect to the emotional consequences, feared (own and other) self-discrepancies were predictive of depressive and anxious mood. With regard to activity patterns, results showed a U-shaped relationship between ideal-other self-discrepancies and persistence behavior and a positive relationship between feared-own self-discrepancies and avoidance behavior. In contrast to expectations, none of the other self-discrepancies was related to activity patterns. Of interest was that avoidance, but not persistence behavior, was predictive of higher levels of disability and lower levels of quality of life. Support is provided for the role of self-discrepancies in the emotional well-being and behavioural patterns of patients with chronic low back pain.

The aim of the present study was to compare the subjectively reported and objectively assessed activity-related characteristics of patients with Chronic Low Back Pain (CLBP) who were classified according to their scores on the Patterns of Activity Measure-Pain (POAM-P) into avoiders, persisters, mixed performers (i.e. high scores on both avoidance and persistence behaviour) or functional performers (i.e. low scores on avoidance and persistence behaviour). Patients carried an electronic diary during 14 days to assess the self-reported activity and pain intensity levels in daily life. An accelerometer was used to objectively assess their activity level during the same time period. Results were available for 79 patients. Avoiders, persisters and mixed performers showed a higher level of self-reported disability than functional performers. Avoiders were characterized by a low level of self-reported habitual activities and persisters by long objectively measured daily uptime. The objectively assessed level of physical activity did not differ between the four groups. A further analysis tested the association between pain intensity levels and self-reported and objectively assessed daily life activity levels in avoiders and persisters. In persisters, a higher level of self-reported activities in daily life was related to increased pain. The objectively assessed activity level was not associated with pain intensity.

Patients with chronic pain may have difficulties estimating their own physical activity level in daily life. Pain-related factors such as depression and pain intensity may affect a patients' ability to estimate their own daily life activity level. This study evaluates whether patients with Chronic Low Back Pain (CLBP) who are more depressed and/or report more pain indeed have a lower objectively assessed daily life activity level or whether they only perceive their activity level as lower. Patients with CLBP were included in a cross-sectional study. During 14days physical activity in daily life was measured, with both an electronic diary and an accelerometer. Multilevel analyses were performed to evaluate whether a higher level of depression and/or pain intensity was associated with a lower objectively assessed activity level or the discrepancy between the self-reported and objectively assessed daily life activity levels. Results, based on 66 patients with CLBP (mean RDQ score 11.8), showed that the objectively assessed daily life activity level is not associated with depression or pain intensity. There was a moderate association between the self-reported and objectively assessed activity levels (beta=0.39, p<0.01). The discrepancy between the two was significantly and negatively related to depression (beta=-0.19, p=0.01), indicating that patients who had higher levels of depression judged their own activity level to be relatively low compared to their objectively assessed activity level. Pain intensity was not associated with the perception of a patient's activity level (beta=0.12, ns).
