Negative language use of the physiotherapist in low back pain education impacts anxiety and illness beliefs: A randomised controlled trial in healthy respondents.

OBJECTIVE: This study aimed to determine the effect of physiotherapists' negative language use on nocebo effects of state anxiety and illness beliefs. METHODS: A web-based randomised controlled trial included adults without recent musculoskeletal pain. The intervention was a short educational video about low back pain using negative language (nocebo condition: n = 87) versus a video using neutral or positive language (control condition: n = 82). State anxiety was assessed using the State-Trait Anxiety Inventory. Illness beliefs were assessed using the Illness Perception Questionnaire. RESULTS: Nocebo and control groups differed in outcome measures (MANOVA Pillai's trace = 0.22, F = 4.98; df = (9,159), p < 0.001). Post-hoc analyses showed a medium to large effect for the nocebo condition on anxiety (d = 0.71, 95% CI 0.4 -1.0). The nocebo group also had higher scores in three illness beliefs: beliefs on timeline (d = 0.45, 95% CI 0.14 - 0.75), treatment control (d = 0.43, 95% CI 0.12 - 0.74) and concern (d = 0.47, 95% CI 0.16 - 0.78). CONCLUSION: Physiotherapists' use of negative language contributes directly to a higher state anxiety and illness beliefs that can trigger the nocebo effects in the recipient PRACTICE IMPLICATIONS: Negative language use should be avoided.

Development and internal validation of a machine learning prediction model for low back pain non-recovery in patients with an acute episode consulting a physiotherapist in primary care.

BACKGROUND: While low back pain occurs in nearly everybody and is the leading cause of disability worldwide, we lack instruments to accurately predict persistence of acute low back pain. We aimed to develop and internally validate a machine learning model predicting non-recovery in acute low back pain and to compare this with current practice and 'traditional' prediction modeling. METHODS: Prognostic cohort-study in primary care physiotherapy. Patients (n = 247) with acute low back pain (≤ one month) consulting physiotherapists were included. Candidate predictors were assessed by questionnaire at baseline and (to capture early recovery) after one and two weeks. Primary outcome was non-recovery after three months, defined as at least mild pain (Numeric Rating Scale > 2/10). Machine learning models to predict non-recovery were developed and internally validated, and compared with two current practices in physiotherapy (STarT Back tool and physiotherapists' expectation) and 'traditional' logistic regression analysis. RESULTS: Forty-seven percent of the participants did not recover at three months. The best performing machine learning model showed acceptable predictive performance (area under the curve: 0.66). Although this was no better than a'traditional' logistic regression model, it outperformed current practice. CONCLUSIONS: We developed two prognostic models containing partially different predictors, with acceptable performance for predicting (non-)recovery in patients with acute LBP, which was better than current practice. Our prognostic models have the potential of integration in a clinical decision support system to facilitate data-driven, personalized treatment of acute low back pain, but needs external validation first.

The IASP pain curriculum for undergraduate allied health professionals: educators defining competence level using Dublin descriptors.

BACKGROUND: Improving pain education for undergraduate health professionals is hampered by lacking shared education outcomes. This study describes how educators and pain experts operationalize content and competency levels deemed necessary for a undergraduate pain education core curriculum for health professionals (physical and occupational therapists, nurses, psychologists). METHODS: Educators and experts on pain and pain education gave their opinion on content and competency level for each individual item of the International Association for the Study of Pain (IASP) inter professional curriculum. Participants decided whether or not to include each item in the undergraduate curriculum. Items were included when > 70% of the respondents agreed. The required competency for each item was rated using ordinal Dublin Descriptors. RESULTS: Overall, 22 experts rated the curriculum, with > 70% agreement on inclusion on 62% of the IASP items. Within the IASP domain 'Multidimensional nature of pain' there was full agreement on the inclusion of 12 items. 'Ethics' was considered less important with only 1 item deemed necessary. There is a high number of items selected within the domains 'Pain Assessment and measurement' (78%) and 'Management of Pain' (74%). Considerably less items were chosen in the domain 'Clinical Conditions' (41%). For most items the median required skills and competency level was either Knowledge and Understanding, or Applying Knowledge and Understanding. CONCLUSION: Overall, educators and experts in pain agreed on content and competency levels for an undergraduate pain curriculum based on the IASP. Defining a shared competency level will help improve definition of education outcome.

Use and perceived added value of patient-reported measurement instruments by physiotherapists treating acute low back pain: a survey study among Dutch physiotherapists.

BACKGROUND: This study aims to explore (i) physiotherapists' current use in daily practice of patient-reported measurement instruments (screening tools and questionnaires) for patients with acute low back pain (LBP), (ii) the underlying reasons for using these instruments, (iii) their perceived influence on clinical decision-making, and (iv) the association with physiotherapist characteristics (gender, physiotherapy experience, LBP experience, overall e-health affinity). METHODS: Survey study among Dutch physiotherapists in a primary care setting. A sample of 650 physiotherapists recruited from LBP-related and regional primary care networks received the survey between November 2018 and January 2019, of which 85 (13%) completed it. RESULTS: Nearly all responding physiotherapists (98%) reported using screening tools or other measurement instruments in cases of acute LBP; the Quebec Back Pain Disability Scale (64%) and the STarT Back Screening Tool (61%) are used most frequently. These instruments are primarily used to evaluate treatment effect (53%) or assess symptoms (51%); only 35% of the respondents mentioned a prognostic purpose. Almost three-quarters (72%) reported that the instrument only minimally impacted their clinical decision-making in cases of acute LBP. CONCLUSIONS: Our survey indicates that physiotherapists frequently use patient-reported measurement instruments in cases of acute LBP, but mostly for non-prognostic reasons. Moreover, physiotherapists seem to feel that current instruments have limited added value for clinical decision-making. Possibly, a new measurement instrument (e.g., screening tool) needs to be developed that does fit the physiotherapist's needs and preferences. Our findings also suggest that physiotherapist may need to be more critical about which measurement instrument they use and for which purpose.

Imaging versus no imaging for low back pain: a systematic review, measuring costs, healthcare utilization and absence from work.

PURPOSE: Imaging (X-ray, CT and MRI) provides no health benefits for low back pain (LBP) patients and is not recommended in clinical practice guidelines. Whether imaging leads to increased costs, healthcare utilization or absence from work is unclear. Therefore, this study systematically reviews if imaging in patients with LBP leads to an increase in these outcomes. METHODS: We searched PubMed, CINAHL, EMBASE, Cochrane Library and Web of Science until October 2017 for randomized controlled trials (RCTs) and observational studies (OSs), comparing imaging versus no imaging on targeted outcomes. Data extraction and risk of bias assessment was performed independently by two reviewers. The quality of the body of evidence was determined using GRADE methodology. RESULTS: Moderate-quality evidence (1 RCT; n = 421) supports that direct costs increase for patients undergoing X-ray. Low-quality evidence (3 OSs; n = 9535) supports that early MRI may lead to an increase in costs. There is moderate-quality evidence (1 RCT, 2 OSs; n = 3897) that performing MRI or imaging (MRI or CT) is associated with an increase in healthcare utilization (e.g., future injections, surgery, medication, etc.). There is low-quality evidence (5 OSs; n = 15,493) that performing X-ray or MRI is associated with an increase in healthcare utilization. Moderate-quality evidence (2 RCTs; n = 667) showed no significant differences between X-ray or MRI groups compared with non-imaging groups on absence from work. However, low-quality evidence (2 Oss; n = 7765) did show significantly greater mean absence from work in the MRI groups in comparison with the non-imaging groups. CONCLUSIONS: Imaging in LBP may be associated with higher medical costs, increased healthcare utilization and more absence from work.

Tailored cognitive-behavioural therapy and exercise training improves the physical fitness of patients with fibromyalgia.

OBJECTIVES: Patients with fibromyalgia have diminished levels of physical fitness, which may lead to functional disability and exacerbating complaints. Multidisciplinary treatment comprising cognitive-behavioural therapy (CBT) and exercise training has been shown to be effective in improving physical fitness. However, due to the high drop-out rates and large variability in patients' functioning, it was proposed that a tailored treatment approach might yield more promising treatment outcomes. METHODS: High-risk fibromyalgia patients were randomly assigned to a waiting list control group (WLC) or a treatment condition (TC), with the treatment consisting of 16 twice-weekly sessions of CBT and exercise training tailored to the patient's cognitive-behavioural pattern. Physical fitness was assessed with two physical tests before and 3 months after treatment and at corresponding intervals in the WLC. Treatment effects were evaluated using linear mixed models. RESULTS: The level of physical fitness had improved significantly in the TC compared with the WLC. Attrition rates were low, effect sizes large and reliable change indices indicated a clinically relevant improvement among the TC. CONCLUSIONS: A tailored multidisciplinary treatment approach for fibromyalgia consisting of CBT and exercise training is well tolerated, yields clinically relevant changes, and appears a promising approach to improve patients' physical fitness.

Cognitive-behavioral mechanisms in a pain-avoidance and a pain-persistence treatment for high-risk fibromyalgia patients.

OBJECTIVE: The heterogeneity of cognitive-behavioral patterns in patients with fibromyalgia (FM) has been proposed to underlie the variability in treatment outcomes. It has previously been shown that pain-avoidance and pain-persistence treatments tailored to the patient's pattern are effective in improving physical and psychological functioning and overall impact in high-risk patients with heightened psychological distress. In the present study, the cognitive-behavioral effects of these treatments were evaluated to provide insight into the main proposed mechanisms, specifically pain-avoidance behaviors and activity pacing in the pain-avoidance and pain-persistence treatments, respectively. METHODS: High-risk FM patients were classified into 2 groups, pain avoidance and pain persistence, and randomized in groups to the relevant treatment or waiting-list control condition. The pain-avoidance and pain-persistence treatments both comprised 16 twice-weekly sessions of cognitive-behavioral therapy and exercise training. Cognitive--behavioral factors assessed at pre- and posttreatment and 6 months of followup were evaluated using linear mixed models. RESULTS: A significant treatment effect was found for pain-avoidance behavior in the pain-avoidance treatment and for activity pacing in the pain-persistence treatment, showing improvements in the treatment condition relative to the controls. Furthermore, the effect on functioning was mediated by changes in pain-avoidance behavior in the pain-avoidance treatment and by changes in activity pacing in the pain-persistence treatment. Both treatments also showed significant improvements in other relevant cognitive-behavioral factors. CONCLUSION: Both the pain-avoidance and pain-persistence treatments are effective in improving cognitive-behavioral factors in high-risk FM patients. Pain-avoidance behavior and activity pacing might be important mediating mechanisms for beneficial outcomes in pain-avoidance and pain-persistence treatments, respectively.

Making the rheumatologist aware of patients' non-adherence does not improve medication adherence in patients with rheumatoid arthritis.

OBJECTIVES: We have developed an instrument that provides the physician structured information about medication use and patients' (non-)adherence. This study aimed to determine the effectiveness of this instrument on adherence and medication beliefs in outpatients with rheumatoid arthritis (RA). METHODS: In this within-subject controlled prospective cohort study, 50 outpatients were assessed during three consecutive visits to their rheumatologist. At these three points in time, patients' adherence, medication beliefs, satisfaction about information about medication, and physical functioning were measured using validated self-report questionnaires. An intervention was scheduled during the second visit. The intervention consisted of a written report informing the physician about medication use and adherence to medication for each patient. The effectiveness of the intervention was evaluated by comparing outcome measures at the third visit to the same measures assessed prior to the intervention. RESULTS: At baseline, 30% of the patients (n = 50) were non-adherent. No significant changes in adherence were found between the first and second visit prior to the intervention. Adherence did not change after the intervention, compared to both of the adherence assessments prior to the intervention. Beliefs about medication, patients' satisfaction about information on medication, and physical functioning were also not significantly altered. CONCLUSION: Supplying the rheumatologist a report with information about medication use and adherence did not change adherence or patients' beliefs about medication. Further research is necessary to ensure effective support for adherence for individual patients with RA.

Age-related health hazards in old patients with first-time referral to a rheumatologist: a descriptive study.

Objective. To study the prevalence of generic age-related health hazards in elderly patient referred to a rheumatologist. Methods. Patients aged 75 or older referred to a specialized gerontorheumatological outpatient service over a period of 2 years were studied prospectively to determine the prevalence of comorbidities, a history of falls, inactivity, cognitive dysfunction, loneliness, and depression in this patient group. Results. A group of 154 patients were included in the study. Comorbidities were observed in 88% of the patients. At least one fall was reported in the last year by 44% of the patients; 44% of the patients reported low levels of health-enhancing physical activity. Depressed mood and loneliness were elevated in 30% and 31% of the patients, respectively. Mild or moderate cognitive impairment was observed in 13% of the patients. Conclusion. Patients in this study were characterized by poor physical ability, high levels of pain, and high prevalence of age-related health hazards.

Screening methods for the detection of antibiotic residues in slaughter animals: comparison of the European Union Four-Plate Test, the Nouws Antibiotic Test and the Premi®Test (applied to muscle and kidney).

Microbial growth inhibition tests are widely used as the primary screening approach for the detection of antibiotic residues in slaughter animals. In this study we evaluated and compared the performance of the European Union Four-Plate Test (EU4pt), the Nouws Antibiotic Test (NAT), and a commercial ampoule test, the PremiTest (applied to both muscle and kidney), by parallel analysis of 735 slaughter animals. The EU4pt only showed significant inhibition with two muscle samples containing 305 µg kg(-1) doxycycline and 648 µg kg(-1) tulathromycin, while an maximum residue limit (MRL) violation of 1100 µg kg(-1) sulfamethazine remained unnoticed. PremiTest-muscle only detected the sulfamethazine containing sample, all other (1.1%) suspect samples appeared false-positive results. The same test applied to kidney yielded 4.1% suspect samples, while the NAT screening (based on analysis of renal pelvis fluid) showed 4.9% suspect results. The vast majority of these samples contained tetracycline and/or aminoglycoside residues. PremiTest-kidney appeared to be more sensitive to aminoglycosides than the NAT screening, which failed to detect an MRL violation of 870 µg kg(-1) gentamicin in kidney. Detection of less than MRL levels of tetracycline residues by the NAT proved its suitability for this residue group. Whether PremiTest is sufficiently sensitive for accurate tetracycline detection in kidney remains doubtful, although changing over to kidney definitely improved the suitability of PremiTest for the detection of residues in slaughter animals.

Swan neck deformities in rheumatoid arthritis: a qualitative study on the patients' perspectives on hand function problems and finger splints.

OBJECTIVE: To identify hand function problems and the reasons for choosing a specific finger splint in patients with rheumatoid arthritis (RA) and swan neck deformities. METHODS: A qualitative study was performed alongside a randomized, controlled cross-over trial comparing the effectiveness of two types of finger splints (the silver ring splint [SRS] and the prefabricated thermoplastic splint [PTS]) in 50 patients with RA and swan neck deformities. Questions on the patients' main hand function problem and reasons for choosing a specific splint type were performed at baseline and after using each splint. The qualitative analyses included the identification of meaning units and (sub)concepts related to hand function problems and splint preferences. RESULTS: RA patients with swan neck deformities experience problems with flexion initiation, painful proximal interphalangeal joint hyperextension, grip activities and comprehensive hand function activities. Reasons for preferring or not preferring a specific type of finger splint included: effect, ease of use, appearance, comfort and side effects. Apart from the splint slipping off and a negative attitude towards the appearance of the splint, which appeared to be more frequently mentioned in connection with the SRS, no clear pattern of positive or negative appreciation of either type of splint could be distinguished. CONCLUSION: RA patients with swan neck deformities experience a variety of problems, including impairments in functions and limitations in daily activities. With the prescription of finger splints, a substantial number of potentially positive and negative consequences of their use need to be taken into account.

Exploring the public health impact of an intensive exercise program for patients with rheumatoid arthritis: a dissemination and implementation study.

OBJECTIVE: To evaluate the implementation of an intensive group exercise program in patients with rheumatoid arthritis (RA). METHODS: In 4 regions in The Netherlands, the Rheumatoid Arthritis Patients In Training exercise program was implemented on a limited scale. Evaluation using the RE-AIM model included: Reach, the proportion of the target population participating; Efficacy, effects on muscle strength, aerobic capacity, functional ability, and psychological functioning; Adoption, program adoption by stakeholders; Implementation, intervention quality (quality audits); and Maintenance, stakeholders' willingness to continue the program in the future. RESULTS: Twenty-five physical therapists from 14 practices were trained to provide the program. In total, 150 RA patients were recruited (by estimation, 2% of the target population). Of the 81 patients who had finished the 12-month intervention and were available for followup directly after the intervention, 62 patients provided clinical data. Muscle strength improved significantly, whereas aerobic capacity, functional ability, psychological functioning, and disease activity did not change. All 9 informed local patient organizations facilitated patient recruitment, and 35 of 51 rheumatologists involved referred one or more patients. All 10 approached health insurance companies funded the program for 12 months. The quality audits showed sufficient quality in 9 of 12 practices. All of the providers of the program were willing to provide the program in the future, whereas future reimbursement by health insurance companies remained unclear. CONCLUSION: The implementation of an intensive exercise program for RA patients on a limited scale can be considered successful regarding its reach, adoption, and implementation. The limited effectiveness and the limited data regarding maintenance warrant additional research.

Obstacle avoidance in persons with rheumatoid arthritis walking on a treadmill.

OBJECTIVE: Patients with rheumatoid arthritis (RA) are at increased risk of falling. In healthy elderly persons with a history of falling, a reduced ability to avoid obstacles while walking has been shown to relate to increased fall risk. The aim of this study was to determine whether this potential risk factor for falls would also be present in persons with RA. METHODS: Twelve RA patients and twelve controls performed an obstacle avoidance task on a treadmill. The obstacle was released during three different phases of the gait cycle (late stance, early swing and mid swing) to create increasing difficulty levels. The primary outcome measure was failure rate. RESULTS: Overall, the RA patients had significantly higher obstacle avoidance failure rates. To avoid an obstacle, a long or a short stride strategy can be used, the choice of which depends on the phase of obstacle release. There were no significant group differences in the distribution of obstacle avoidance strategies. However, the RA patients made significantly more failures when performing a short stride strategy in mid swing obstacle release trials (the condition which gave the patients the least time to react; available response time). In addition, compared to the controls, the RA group approached the obstacle more closely prior to obstacle crossing (shorter toe distance), thereby increasing the risk of stumbling. CONCLUSION: Obstacle avoidance performance in persons with RA is significantly deteriorated compared to age- and gender-matched controls, especially when available response time is low. This deficit may contribute to their higher fall risk.

Effectiveness of two finger splints for swan neck deformity in patients with rheumatoid arthritis: a randomized, crossover trial.

OBJECTIVE: To compare the effectiveness and acceptability of silver ring splints (SRS) and commercial prefabricated thermoplastic splints (PTS) in treating swan neck deformities in patients with rheumatoid arthritis (RA). METHODS: Consecutive patients with RA and a mobile swan neck deformity were included in a randomized, crossover trial. In 2 different sequences, patients used both splints for 4 weeks, with a washout period of 2 weeks. Afterward, patients used the preferred splint for another 12 weeks. The primary outcome measure was dexterity measured with the Sequential Occupational Dexterity Assessment (SODA). Secondary outcome measures included other measures of hand function, satisfaction with the splints, and splint preference. RESULTS: Fifty patients were included, and 47 (94%) of those completed the study. Eighteen patients (36%) had 1 swan neck deformity, whereas the other patients had 2 or more. The improvement of the total SODA score with the SRS (11.2; 95% confidence interval [95% CI] 8.1, 14.3) and PTS (10.8; 95% CI 7.5, 14.1) was similar (difference -0.5; 95% CI -2.2, 1.2). In addition, there were no significant differences in change scores regarding the other clinical outcome measures, or satisfaction. Twenty-four patients preferred the SRS, 21 preferred the PTS, and 2 patients chose neither. A comparison in the 12-week followup period yielded similar clinical outcomes, with the exception of a significantly higher score in 3 items of satisfaction in the SRS group. CONCLUSION: For patients with RA and a mobile swan neck deformity, SRS and PTS are equally effective and acceptable.

Screening for pain-persistence and pain-avoidance patterns in fibromyalgia.

BACKGROUND: The heterogeneity of patients regarding pain-related cognitive-behavioral mechanisms, such as pain-avoidance and pain-persistence patterns, has been proposed to underlie varying treatment outcomes in patients with fibromyalgia (FM). PURPOSE: To investigate the validity of a screening instrument to discriminate between pain-persistence and pain-avoidance patterns in FM. METHOD: In a three-part study, a self-reported screening instrument that assesses pain-avoidance behavior was used to distinguish patients with pain-persistence and pain-avoidance patterns. The resultant groups were compared with regard to several pain-related cognitive-behavioral factors, performance on a physical fitness test, and with regard to the judgments of trained therapists based on a semi-structured interview. RESULTS: The validity of the screening instrument to distinguish between pain-avoidance and pain-persistence patterns was supported by other validated self-report questionnaires for pain-related cognitive-behavioral factors, physical exercise tests, as well as by a high correspondence with blinded therapist judgment after intake assessments. CONCLUSION: These findings suggest that a short self-report screening instrument can be used to distinguish between pain-avoidance and pain-persistence patterns within the heterogeneous population of FM patients, which offers promising possibilities to improve treatment efficacy by tailoring treatment to specific patient patterns.

Tailored cognitive-behavioral therapy for fibromyalgia: two case studies.

OBJECTIVE: To illustrate a multidisciplinary group treatment for patients with fibromyalgia (FM) tailored to the patient's cognitive-behavioral pattern. METHOD: In a case-study design the tailored treatment approaches of two FM patients were described. One patient characterized by avoidance behavior (pain-avoidance pattern) participated in a group treatment aimed at changing pain-avoidance mechanisms and one patient characterized by continuing with activities in spite of pain (pain-persistence pattern) participated in a group treatment aimed at changing pain-persistence mechanisms. Assessments were made at baseline, post-treatment and at 6-months follow-up. RESULTS: Comparison of the pretest, post-test and follow-up scores on pain, functional disability, fatigue and psychological distress showed clinically significant improvements for both patients. CONCLUSION: The heterogeneity of patients regarding pain-related cognitive-behavioral mechanisms has been proposed to underlie varying treatment outcomes in FM patients. These results demonstrate that a group treatment tailored to pain-avoidance and pain-persistence patterns is feasible and can result in clinically significant changes for FM patients. PRACTICE IMPLICATIONS: FM offers a great challenge for clinicians due to the lack of effective treatment options. These case studies suggests that tailored CBT and exercise training directed at specific patient patterns can contribute to the improvement of the care of FM patients.

Collaborative study of a microbiological screening method (three-plate) for the banned antimicrobial growth promotors tylosin, virginiamycin, spiramycin, zinc bacitracin and avoparcin in animal feed.

A microbiological screening method (three-plate) for the detection of the antimicrobial growth promoters tylosin, spiramycin, virginiamycin, zinc bacitracin, and avoparcin in animal feed has been developed and validated successfully. A collaborative study involving 18 laboratories receiving 172 samples was carried out to verify the performance characteristics. The detection level for tylosin/virginiamycin/spiramycin, expressed in microbiological activity, was 1 mg kg(-1) (false-positives, 2%; false-negatives, 3, 0, and 6%, respectively). Avoparcin could be detected at 1 mg kg(-1) in feed in general (false-positives, 2%; false-negatives, 0%). However, in calf feed the sensitivity was lower. The percentages of false-negatives were found to be 12%, 7%, and 0% at 1, 3, and 5 mg kg(-1), respectively (false-positives, 4%). The limit of detection for zinc bacitracin was 3-5 mg kg(-1) (false-positives, 5-10%; false-negatives, 77% at 1 mg kg(-1), 45% at 2 mg kg(-1), 12% at 3 mg kg(-1), and 4% at 5 mg kg(-1)). The method allowed for a distinction to be made between the groups of antibiotics: avoparcin/zinc bacitracin versus tylosin/virginiamycin/spiramycin. This definitely gives added value to the method in the framework of a follow-up of positive screening results by post-screening and confirmatory analysis.

Appearance self-esteem in systemic sclerosis--subjective experience of skin deformity and its relationship with physician-assessed skin involvement, disease status and psychological variables.

OBJECTIVES: To determine the importance of skin deformity in systemic sclerosis (SSc) relative to other disease stressors and to find psychological correlates of appearance self-esteem (ASE) after controlling for disease status. METHODS: Disease-related stressors, symptoms, physical and psychological functioning, social support, coping styles, cognitions and ASE were assessed in 123 patients with SSc. A rheumatologist determined disease duration, SSc subtype, presence of organ involvement and skin-thickness scores. Stepwise hierarchical regression analysis of disease-related cognitions on ASE was performed after controlling for selected variables. RESULTS: Skin deformities proved a core stressor of the disease, only preceded by fatigue. Physician-assessed disease status, including modified Rodnan skin score, was unrelated to ASE. Sex, self-reported functioning and symptoms were related to ASE and used as control variables. Both acceptance and anxiety correlated strongly with ASE. The stepwise regression procedure only identified the disease-related cognition acceptance. CONCLUSIONS: In SSc, ASE proved unrelated to the extent of skin thickness. Psychological interventions aimed at boosting ASE should primarily target the psychological factors acceptance and anxiety.

Somatoform dissociation and traumatic experiences in patients with rheumatoid arthritis and fibromyalgia.

OBJECTIVE: Trauma and dissociation tend to be interrelated. The objective of this study was to examine the frequency of traumatic experiences and somatoform dissociation in patients with fibromyalgia syndrome (FMS) or rheumatoid arthritis (RA), two conditions that are both characterized by pain and disability. METHODS: Patients with a diagnosis of FMS (2 male, 26 female; mean age 42 +/- 11 years) or RA (5 male, 46 female; mean age 46 +/- 10 years) completed the Fibromyalgia Impact Questionnaire (FIQ), the Somatoform Dissociation Questionnaire (SDQ), and the Traumatic Experience Checklist (TEC). RESULTS: Patients with FMS reported significantly higher levels of various forms of traumatization and dissociation than patients with RA. In patients with FMS, but not in patients with RA, there was a significant correlation between traumatization and dissociative symptoms. A possible dissociative disorder was indicated in 10% of the patients with FMS and 2% of the patients with RA. CONCLUSION: Traumatization experiences are frequent in FMS, but as compared to conversion disorder or dissociative identity disorder only a small subgroup of patients with FMS or RA shows the combination of traumatization and somatoform dissociation. The observation of somatoform dissociation calls for a broad treatment approach with a special role of the psychologist or psychiatrist.
