We conclude that the Internet-based cognitive-behavioural intervention was at least as effective as the face-to-face group intervention and, on some outcome measures appeared to be even more effective.

This guideline provides recommendations in support of daily practice and is based on the results of scientific research and further discussions focussed on establishing good medical practice.

Cross sectional study, performed in an outpatient university based pain rehabilitation setting. To analyze the relationship between psychological factors (psychosocial distress, depression, self efficacy, self-esteem, fear of movement, pain cognitions and coping reactions) and performance-based and self-reported disability, as measured with a Functional Capacity Evaluation (FCE) and the Roland Morris Disability Questionnaire (RMDQ), in patients with chronic low back pain (CLBP). It has been suggested that a strong relationship exists between psychological factors and disability in patients with CLBP. In former research disability was often measured by self-report and seldom performance-based. Study sample consisted of 92 patients with CLBP admitted for multidisciplinary rehabilitation. Prior to treatment, all patients completed questionnaires to measure psychological factors and self-reported disability, and performed an FCE to measure performance-based disability. Correlation coefficients between psychological variables and FCE and self-reported disability were calculated. Multivariate linear regression analyses were performed with self-reported or performance based disability measures as outcome variables, and psychological measures as predictor variables. Out of 42 relations analyzed, 5 were statistically significant. This concerned one significant correlation between kinesiophobia and a subtest of FCE, and four correlations between psychological factors and RMDQ. No correlation was significant after the Bonferroni correction was applied (P < 0.001). The strength of significant correlations ranged from r = −0.33 to r = 0.25. The multivariate analysis revealed that psychological variables measured in this study could explain 19% of the variance of self-reported disability, with kinesiophobia being the only psychological variable that contributed significantly. The suggested strong relationship between psychological factors and performance-based and self-reported disability could not be confirmed in this study. This may implicate that the relationship between psychological factors and disability in patients with CLBP is not as unambiguous as suggested.

ObjectivesCatastrophizing is often the primary target of the cognitive-behavioral treatment of chronic pain. Recent literature on acceptance and commitment therapy (ACT) suggests an important role in the pain experience for the concepts mindfulness and acceptance. The aim of this study is to examine the influence of mindfulness and general psychological acceptance on pain-related catastrophizing in patients with chronic pain.MethodsA cross-sectional survey was conducted, including 87 chronic pain patients from an academic outpatient pain center.ResultsThe results show that general psychological acceptance (measured with the AAQ-II) is a strong predictor of pain-related catastrophizing, independent of gender, age and pain intensity. Mindfulness (measured with the MAAS) did not predict levels of pain-related catastrophizing.DiscussionAcceptance of psychological experiences outside of pain itself is related to catastrophizing. Thus, acceptance seems to play a role in the pain experience and should be part of the treatment of chronic pain. The focus of the ACT treatment of chronic pain does not necessarily have to be on acceptance of pain per se, but may be aimed at acceptance of unwanted experiences in general. Mindfulness in the sense of “acting with awareness” is however not related to catastrophizing. Based on our research findings in comparisons with those of other authors, we recommend a broader conceptualization of mindfulness and the use of a multifaceted questionnaire for mindfulness instead of the unidimensional MAAS.

During the 25-year period 1970-1994 694 patients were diagnosed with neck sprain resulting from a car accident at the Emergency Room of the University Hospital Groningen. The purpose of the present study was to analyse the prevalence, groups at risk and trends in these patients, taking into account changes in the number of cars per inhabitant and the average number of kilometres driven. We defined the population as car accident victims diagnosed with neck sprain. Binominal tests were used to obtain measures of statistical significance. Over the 25-year period a steady increase in the number of these patients was observed, from 10 in 1970 to 122 in 1994. The highest prevalence was found for the age group 25- to 29-year olds (28.3 per 100,000), followed by 40- to 44-year-olds (27.9 per 100,000). Across the life span, the male: female ratio was 1: 0.98. Eight percent of the victims were treated as inpatients. The increase in the number of car accident victims with neck sprain appears not to be an isolated phenomenon, because a parallel rise in the number of cars per inhabitant and in the average number of kilometres driven was found. No direct relation was observed between seat belt legislation and the increase in neck sprain injuries. The effect of the media on awareness of the consequences of car accidents is discussed.

Background: Catastrophizing is a defining factor in the pain experience and strongly contributes to the prediction of various aspects of health. Catastrophizing is not just present in pain patients, but may also be present in people with non-clinical pain. The aim of the present study is to investigate levels of catastrophizing in pain patients and people with pain from the general population. Also, the relationship between catastrophizing and pain intensity, specialist consultation and use of pain medication is studied. Methods: A cross-sectional survey design was used, including 150 pain patients and 376 respondents from the general population. Results:The results show that pain is highly prevalent in the general population. The pain patients reported significantly higher levels of pain intensity and catastrophizing than the community pain sample. In both samples, significant positive correlations between catastrophizing and pain intensity were found. The data show a linear relationship between catastrophizing and pain intensity, which can be interpreted as evidence for a dose-response pattern in pain-related catastrophizing. Furthermore, catastrophizing predicted specialist consultation and medication use in the community pain sample. Conclusions: It can be concluded that pain-related catastrophizing is present in pain patients as well as people with pain from the general population in a dose-response pattern. Catastrophizing seems to be an important factor determining certain aspects of pain-related medical consumption, even in non-clinical pain, and should therefore be a target of the screening procedure and early intervention.
