Adolescents' needs for information and psychosocial support during their mother's breast cancer trajectory: A systematic review.

OBJECTIVE: Breast cancer is the most common cancer diagnosis among women. The acute crisis and uncertainty that often follow diagnosis put the family at risk of exhaustion and dysfunction. Adolescents have been identified as a particularly vulnerable group of relatives. To investigate how to prevent distress in this group, we systematically reviewed research on adolescents' (11-21 years) needs for information and psycho-social support during their mothers' breast cancer trajectory. METHOD: Systematic searches were conducted in five bibliometric databases. Peer-reviewed, original research of adolescents aged 11-21 with a mother diagnosed with breast cancer was included. Two researchers conducted screening, quality assessment, and data extraction independently. Thematic synthesis was applied to the included studies. RESULTS: A total of 8066 studies were screened, and five quantitative and six qualitative studies were included. The results indicated that adolescents' information and psycho-social support needs were poorly met. Many were reluctant to share feelings with family and peers and experienced abandonment during the crisis. Adolescents who were not well informed experienced distress. Poor family functioning increased the level of adolescents' distress. CONCLUSIONS: Despite limitations regarding heterogeneity among the studies, eligibility criteria, and quality assessment, this review provides clear clinical implications. Encounter groups may support adolescents during their mother's breast cancer trajectory. Furthermore, healthcare professionals could provide more indirect support to adolescents by providing support and clearer guidelines to parents. Finally, adolescents from poor-functioning families need extra attention.

Content of clinicians' communication with patients suffering from spinal pain in assessment situations in a specialized spine center: A qualitative study evaluating psychologically informed pain assessments before and after clinicians' participation in an Acceptance and Commitment Therapy course.

INTRODUCTION: Assessment is an important part of chronic pain rehabilitation and should be conducted in line with the current biopsychosocial conceptualization of pain to capture the subjectivity and context of pain. However, pain assessment is commonly conducted from a biomedical framework. A course in Acceptance and Commitment Therapy (ACT) was provided to spinal pain clinicians as a framework to promote more person-centered and psychosocially focused assessments and related psychologically informed practices. The purpose of this qualitative study was to explore the verbal content of clinicians' communication with patients experiencing spinal pain in assessment situations before and after clinicians participated in an ACT course. METHODS: Pain assessments of patients with chronic low back pain conducted by six spinal pain clinicians from different professions were audio-recorded and transcribed. This was done before and after participation in an eight-day ACT course with four following supervisions. A thematic analysis was carried out by two authors across all material, and a comparison of the applied number of codes pre-course and post-course was carried out as an indicator of change. RESULTS: Data consisted of transcripts from the six clinicians across 23 different patients (12 before course participation). Through analysis, 11 codes were developed, which were clustered in three overarching themes: Psychological domains, Communication Techniques, and Intervention Elements. Overall, there was an increase in the application of many of the codes in the transcripts from pre-course to post-course, however with large differences across codes. Increases were primary related to the discussion of life values and value-based action and quality of life as well as the employment of mirroring, challenging beliefs and assumptions, and addressing coping and pacing. CONCLUSIONS: While not the case for all factors, the present findings indicate an increase in including psychological factors and employing interpersonal communication skills after a course in ACT. However, it remains unknown due to the design if the changes reported in this study reflect a clinically valuable change and whether they are due to the ACT training itself. Future research will improve our understanding of the effectiveness of this type of intervention in assessment practices.

There's Nothing Broken. You've Had a Whiplash, That's It: A Qualitative Study of Comorbid Posttraumatic Stress Disorder and Whiplash Associated Disorders.

BACKGROUND: Posttraumatic stress disorder (PTSD) symptoms are common in chronic Whiplash associated disorders (WAD) and have been found to be associated with higher levels of pain and disability. Theoretical frameworks have suggested that PTSD and pain not only coexist, but also mutually maintain one another. Although the comorbidity has been subject to increasing quantitative research, patients' experiences of the comorbidity and symptom interaction remain largely uninvestigated using qualitative methods. OBJECTIVE: The present study set out to explore the potential relationship of PTSD and pain in people with WAD and properly assessed PTSD after motor vehicle accidents. METHODS: A qualitative explorative study of eight individual face-to-face semistructured interviews were conducted. Interviews were recorded and transcribed verbatim and analyzed using framework analysis. RESULTS: Through the analysis, we developed three overarching themes. The first theme illustrated the complex and burdensome comorbidity with overlapping and transdiagnostic symptoms, whereas the second theme highlighted how several circumstances, some related to the health care system, could extend and amplify the traumatic response. The final theme illustrated symptom associations and interactions, particularly between pain and PTSD, both supporting and rejecting parts of the mutual maintenance framework. CONCLUSIONS: These findings underlined the great complexity and variability of the comorbidity and the traumatic event, but also emphasized how experiences of psyche and soma seem closely connected in these patients. The results provide support for the importance of thorough assessment by multidisciplinary teams, minimizing distress post-injury, and a critical approach to the idea of mutual maintenance between pain and PTSD.

The associations of acceptance with quality of life and mental health following spinal cord injury: a systematic review.

STUDY DESIGN: Systematic review. OBJECTIVES: To identify, critically appraise, and synthesize research findings on the associations between acceptance, quality of life (QOL), and mental health outcomes in individuals living with spinal cord injury (SCI). METHODS: Five databases (PubMed, PsycINFO, Embase, Web of Science, and Scopus) were systematically searched. Studies were included if they provided findings on the association between acceptance and QOL, mental health outcomes, or both in an SCI population aged 16 years or older. Only peer-reviewed original quantitative and qualitative studies were included. Screening, quality assessment, and data extraction were conducted independently by two researchers. Findings were tabulated and synthesized by outcome. RESULTS: Forty-one studies were included. Greater acceptance was consistently associated with greater global and psychological QOL, life satisfaction, sense of well-being, mental health, and with lower levels of depression and anxiety. Inconsistent evidence was found with regards to social QOL and post-traumatic stress disorder. Acceptance was generally not associated with adjustment outcomes further than 2 years into the future. Study quality of the quantitative studies was mostly fair (n = 17) followed by good (n = 13), and poor (n = 9). CONCLUSION: Health-care professionals may regard acceptance as a psychological resource they can aim to support in improving QOL and mental health following SCI. A range of methodological and conceptual limitations were present in the research. Future studies should prioritize longitudinal designs, consider dyadic effects, explore subjective meaning(s) of acceptance, and investigate the effectiveness of therapeutic approaches that stimulate the acceptance process.

Pain-Related Acceptance as a Mediator in the Fear Avoidance Model of Chronic Pain: A Preliminary Study.

Objective: The fear avoidance model has served as a popular, heuristic model in explaining the transition from acute to chronic pain. In addition, the significance of pain-related acceptance in chronic pain development and adjustment is underlined in a vast number of empirical studies. The objective of the current preliminary study was to investigate pain-related acceptance as a mediator within the key cognitive relationships proposed by the fear avoidance model of chronic pain. Materials and Methods. In a cross-sectional design, bodily pain, pain catastrophizing, fear avoidance beliefs, and pain-related acceptance were assessed by questionnaires in 125 chronic pain patients in a Danish multidisciplinary pain center. Mediation analyses were performed to test the effect of pain-related acceptance on bodily pain, pain catastrophizing, and fear avoidance beliefs. Results: Medium-sized correlations were found between all outcomes. Mediation analyses revealed that pain-related acceptance was a significant mediator between 1) bodily pain and pain catastrophizing and 2) pain catastrophizing and fear avoidance beliefs after controlling for bodily pain. Furthermore, pain-related acceptance accounted for a large proportion in both associations (82.2% and 56.1%). Conclusions: The results suggest that pain-related acceptance is a prominent psychological mechanism within the key cognitive associations of the fear avoidance model, which predicts a certain path of cognitive, emotional, and behavioral factors in the development and maintenance of chronic pain. This proposes pain-related acceptance to be an important mechanism that possibly counteracts the negative reactions of pain catastrophizing and fear avoidance beliefs. These findings should be investigated further and could potentially be an important place to intervene clinically in order to counteract the development and/or maintenance of chronic pain.

Value-based cognitive-behavioural therapy for the prevention of chronic whiplash associated disorders: protocol of a randomized controlled trial.

BACKGROUND: Whiplash injury is the most common traffic-related injury affecting thousands of people every year. Conservative treatments have not proven effective in preventing persistent symptoms and disability after whiplash injury. Early established maladaptive pain behaviours within the first weeks after the injury may explain part of the transition from acute to chronic whiplash associated disorder (WAD). Hence, early targeting of psychological risk factors such as pain catastrophizing, fear-avoidance-beliefs, depression, and symptoms of posttraumatic stress disorder (PTSD) may be important in preventing the development of chronic WAD. Some evidence exists that targeting fear-avoidance beliefs and PTSD with exposure strategies and value-based actions may prevent development of persistent disability after whiplash injury. Yet, the results have to be tested in a randomized controlled trial (RCT). The primary objective of the present study is to test whether a specifically tailored value-based cognitive-behavioural therapy program (V-CBT) is able to prevent the development of persistent disability, pain, and psychological distress if delivered within the first three months after a whiplash injury. METHODS/DESIGN: The current study is a two-armed randomized controlled study with a crossover design. Group A is scheduled for V-CBT within one week of randomization and group B with a delayed onset 3 months after randomization. DISCUSSION: If the study detects significant effects of V-CBT as a preventive intervention, the study will provide new insights of preventive treatment for patients with WAD and thereby serve as an important step towards preventing the chronic condition.

Experiences and reflections on living with a personal assistance service: a qualitative study of people with neuromuscular disease or spinal cord injury.

PURPOSE: To investigate how people with neuromuscular disease or spinal cord injury experience living with a personal assistance service. MATERIALS AND METHODS: Qualitative study using the Interpretive Description methodology with Aaron Antonovsky's theory of sense of coherence as a theoretical framework. The method was semi-structured individual interviews (n = 3) and focus group interviews (n = 5). In all, 19 adults with neuromuscular disease (n = 13) or spinal cord injury (n = 6) participated. The study adhered to the Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines. RESULTS: Three themes were identified to understand living with personal assistance and how this affected everyday life: 1) Making meaning of a personal assistance service, 2) Managing a personal assistance service, and 3) Living with a personal shadow. Our findings provide an understanding of living with assistance and how it, among other things, is influenced by the legislation and the local authorities' administration of the service. Participants explained this by an experience of a sense of coherence. CONCLUSION: For people with NMD and SCI, there are complex nuances associated with living with a personal assistance service. The findings illustrate that despite personal challenges of managing assistance services, it can meaningfully contribute to one's life by enhancing one's sense of coherence.

Policy initiatives are important to help people living with neuromuscular disease (NMD) or spinal cord injury (SCI) access flexible personal assistance services, which can enable them to lead independent lives with enhanced meaningfulness.Professionals of people with NMD and SCI should provide knowledge and counseling on how to manage their personal assistance service, which includes taking into account practical, physical, and psychosocial considerations.To ensure optimizing the design and delivery of personal assistance services for the NMD and SCI populations, it is critical that policymakers are made aware of both the positive and challenging aspects of personal assistance services, and should consider engaging persons with lived experience when developing (or re-evaluating) them.

The Influence of "Labels" for Neck Pain on Recovery Expectations Following a Motor Vehicle Crash: An Online-Randomized Vignette-Based Experiment.

OBJECTIVES: To (1) investigate whether different labels for neck pain after a motor vehicle crash (MVC) influenced recovery expectations and management beliefs, (2) explore reasons for low recovery expectations and greater likelihood for lodging a claim, and (3) explore the moderating effect of neck pain history and sociodemographic characteristics. DESIGN: Online randomized experiment with nested qualitative content analysis. METHODS: We randomized 2229 participants from the general population (mean age: 46.7 ± 17.5 years; 72.4% females; 66% with previous or current neck pain; 10% with an MVC experience) to read 1 of 5 scenarios describing a patient with neck pain after an MVC, each was labeled as whiplash injury, whiplash-associated disorder, posttraumatic neck pain, neck pain, or neck strain. The primary outcome was recovery expectations, rated on a 0- to 10-point scale. RESULTS: Participants allocated to whiplash-associated disorder or neck pain had lower recovery expectations than those allocated to neck strain (adjusted mean difference [95% confidence interval]: -0.5 [-0.9 to -0.1] for both comparisons). Whiplash-associated disorder led to more recovery uncertainty, while neck pain led to greater doubt about the health care provider. Most secondary outcomes showed significant but small differences. Participants allocated to neck strain were less inclined to claim than those allocated to whiplash-associated disorder or whiplash injury due to less perceived need for financial support. Neck pain history moderated labeling effects on recovery expectations; household income moderated the claim intention. CONCLUSIONS: Labels for neck pain after an MVC influenced recovery expectations and management preferences. The clinical relevance of the small effects was unclear.

Interpretation of the Patient Health Questionnaire 9 in High-Impact Chronic Pain: Do We Measure Depressive Symptoms the Way We Think?

OBJECTIVES: Depression is prevalent among patients with chronic pain and may impact pain management. An accurate assessment is, however, complicated by overlapping symptoms. This study investigated how patients with high-impact chronic pain interpreted and responded to the Patient Health Questionnaire 9 (PHQ-9) to identify problematic items and causes hereof. MATERIALS AND METHODS: Cognitive interviews using the Three-Step Test-Interview procedure were conducted during the completion of the PHQ-9 in 33 patients with high-impact chronic pain referred to interdisciplinary treatment. Responses were analyzed using 4 coding categories: (1) "congruent" (response consistent with intention); (2) "incongruent" (response not consistent intention); (3) "ambiguous" (response both congruent and incongruent or insufficient to evaluate congruency); and (4) "confused" (response with confused or misunderstood statements). Next, the content of responses to problematic items was analyzed to identify causes for noncongruency, and encountered response difficulties were identified across all items. RESULTS: Three items (items 2, 6, and 9) performed as intended (>97% congruent responses), while 7 items (items 1, 3, 4, 5, 7, 8, and 10) were identified as problematic (<50% congruent responses). Problematic items had 1 or more issues: Responses were based on (1) pain-related issues or (2) other (non-pain) factors unrelated to depression, or item structure caused response difficulties due to wordings, reversion, or having 2 questions in 1. DISCUSSION: Problematic items limit the construct validity of the PHQ-9, leaving an increased risk of inflated depression scores in high-impact chronic pain. Identified problems should guide future revisions to enhance validity and screening accuracy for the benefit of both research and clinical practice.

Validation of the Danish PTSD Checklist for DSM-5 in trauma-exposed chronic pain patients using the Clinician-Administered PTSD Scale for DSM-5.

Background: Validation of post-traumatic stress disorder (PTSD) screening tools across various populations to ensure accurate PTSD estimates is important. Because of the high symptom overlap between PTSD and pain, it is particularly important to validate PTSD screening tools in trauma-exposed chronic pain patients.Objective: The present study is the first seeking to validate the PTSD Checklist for DSM-5 (PCL-5) in a sample of trauma-exposed, treatment-seeking chronic pain patients.Method: The validation and optimal scoring of the PCL-5 were investigated using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) in chronic pain patients exposed to traffic or work-related traumas (n = 84). Construct validity was investigated using confirmatory factor analyses testing six competing DSM-5 models in a sample of mixed trauma-exposed chronic pain patients (n = 566), and a subsample of chronic pain patients exposed to traffic or work-related trauma only (n = 202). Furthermore, concurrent validity and discriminant validity were investigated using correlation analysis.Results: The results showed moderate (κ = .46) diagnostic consistency between the PCL-5 and the CAPS-5 using the DSM-5 symptom cluster criteria, and the overall accuracy of the scale (area under the curve = .79) was highly acceptable. Furthermore, the Danish PCL-5 showed excellent construct validity both in the full sample and in the subsample of traffic and work-related accidents, with superior fit of the seven-factor hybrid model. Excellent concurrent validity and discriminant validity were also established in the full sample.Conclusion: The PCL-5 appears to have satisfactory psychometric properties in trauma-exposed, treatment-seeking chronic pain patients.

The present study is the first seeking to validate the PCL-5 using the CAPS-5 in chronic pain patients following traffic and work-related injury.The results showed moderate diagnostic consistency and acceptable overall accuracy using the DSM-5 criteria.Excellent construct, concurrent, and discriminant validity was established in chronic pain patients following mixed traumatic exposure and traffic and work-related trauma only.

Investigating the DSM-5 and the ICD-11 PTSD symptoms using network analysis across two distinct samples.

OBJECTIVE: Posttraumatic stress disorder (PTSD) has long been debated with a recent focus on the consequences of having two different diagnostic descriptions of PTSD (i.e., the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition [DSM-5] and the International Classification of Diseases-11th Edition [ICD-11]). Research has modeled PTSD as a network of interacting symptoms according to both diagnostic systems, but the relations between the two systems remain unclear regarding which symptoms are more central or interconnected. To answer this question, the present study is the first study to investigate the combined network structure of PTSD symptoms according to both systems using validated measurements (i.e., the International Trauma Questionnaire [ITQ] and the Posttraumatic Stress Disorder Checklist 5 [PCL-5] across two distinct trauma samples [a community sample, N = 2,367], and a military sample, N = 657). METHOD: We estimated two Gaussian Graphical Models of the combined ICD-11 and DSM-5 PTSD symptoms across the two samples. RESULTS: Five of the six most central symptoms were the same across both samples. CONCLUSIONS: The results underline that a combination of five symptoms representing both diagnostic systems may hold central positions and potentially be important for treatment. However, the implications depend on if the different diagnostic descriptions can be reconciled in an indexical rather than constitutive perspective.

No effect of social interaction on experimental pain sensitivity: a randomized experimental study.

ABSTRACT: Quantitative sensory testing (QST) is a commonly applied paradigm to investigate pain, which is a subjective experience influenced by a myriad of social and contextual factors. Therefore, it is important to consider the potential sensitivity of QST to the test setting and the social interaction that naturally is a part of it. This may particularly be the case in clinical settings where patients have something at stake. Therefore, we investigated differences in pain responses using QST in different test setups with varying degrees of human interaction. In a parallel three-armed randomized experimental study, we included 92 participants with low back pain and 87 healthy volunteers allocated to 1 of the 3 QST setups: 1 setup with manual tests performed by a human tester, 1 setup with automated tests performed by a robot and orally guided by a human tester, and 1 setup with automated tests performed solely by a robot without social interaction with a human tester. All 3 setups consisted of the same pain tests in the same order, including pressure pain threshold and cold pressor tests. We found no statistically significant differences between setups on the primary outcome of conditioned pain modulation nor any secondary QST outcomes. While this study is not without limitations, the results indicate that QST procedures are robust enough not to be influenced by social interaction to an appreciable degree.

Recommendations for a core outcome measurement set for clinical trials in whiplash associated disorders.

ABSTRACT: Inconsistent reporting of outcomes in clinical trials of treatments for whiplash associated disorders (WAD) hinders effective data pooling and conclusions about treatment effectiveness. A multidisciplinary International Steering Committee recently recommended 6 core outcome domains: Physical Functioning, Perceived Recovery, Work and Social Functioning, Psychological Functioning, Quality of Life and Pain. This study aimed to reach consensus and recommend a core outcome set (COS) representing each of the 6 domains. Forty-three patient-reported outcome measures (PROMs) were identified for Physical Functioning, 2 for perceived recovery, 37 for psychological functioning, 17 for quality of life, and 2 for pain intensity. They were appraised in 5 systematic reviews following COSMIN methodology. No PROMs of Work and Social Functioning in WAD were identified. No PROMs had undergone evaluation of content validity in patients with WAD, but some had moderate-to-high-quality evidence for sufficient internal structure. Based on these results, the International Steering Committee reached 100% consensus to recommend the following COS: Neck Disability Index or Whiplash Disability Questionnaire (Physical Functioning), the Global Rating of Change Scale (Perceived Recovery), one of the Pictorial Fear of Activity Scale-Cervical, Pain Self-Efficacy Questionnaire, Pain Catastrophizing Scale, Harvard Trauma Questionnaire, or Posttraumatic Diagnostic Scale (Psychological Functioning), EQ-5D-3L or SF-6D (Quality of Life), numeric pain rating scale or visual analogue scale (Pain), and single-item questions pertaining to current work status and percent of usual work (Work and Social Functioning). These recommendations reflect the current status of research of PROMs of the 6 core outcome domains and may be modified as evidence grows.

Posttraumatic Stress Symptoms and Pain Sensitization After Whiplash Injury: A Longitudinal Cohort Study With Quantitative Sensory Testing.

Posttraumatic stress symptoms (PTSS) are common after whiplash injury and are associated with poor recovery. The acute stress response may lead to pain sensitization and widespread pain, thereby compromising recovery. To our knowledge, no longitudinal study has assessed the associations between early PTSS and pain sensitization over time using quantitative sensory testing (QST). The aim of this study was to compare participants with different levels of PTSS, as measured by the impact of event scale (IES; subclinical 0-8, mild 9-25, and clinical ≥ 26) at baseline (<10-day post-injury) and at a follow-up of 1, 3, 6, and 12-month post-injury on pain sensitivity, neck mobility, pain distribution, and pain intensity. In total, 740 participants were recruited from emergency units or general practitioners with acute neck pain after a whiplash injury. The clinical PTSS group showed increased pain sensitivity on all QSTs at all time points compared to the subclinical PTSS group. Also, the clinical PTSS group showed significantly lower neck mobility at all time points except for a 3-month follow-up compared to the subclinical PTSS group. Moreover, the clinical PTSS group showed more widespread pain and self-reported headache and neck pain intensity at all time points compared to the subclinical PTSS group. This study emphasizes that participants with clinical levels of PTSS constitute a high-risk group that is sensitized to pain early after the injury. Hence, screening for PTSS within the 1st week after whiplash injury for those who experience high levels of pain intensity and distress may be an important clinical procedure in the assessment and treatment of whiplash-associated disorders (WAD).

A systematic review shows minimal evidence for measurement properties of psychological functioning outcomes in whiplash.

OBJECTIVES: The aim of this study was to systematically identify, synthesize, and appraise studies on the measurement properties of patient-reported outcome measures (PROMs) for anxiety, depression, fear of movement, pain catastrophizing, post-traumatic stress, self-efficacy, and stress in people with whiplash-associated disorders (WAD). STUDY DESIGN AND SETTING: PsycINFO, MEDLINE, EMBASE, CINAHL, PILOTS, Web of Science, and Scopus were searched (November 9, 2021). Studies evaluating any measurement property of relevant PROMs in WAD were included. Two reviewers independently screened the studies and assessed the measurement properties in accordance with the COSMIN guidelines. RESULTS: Measurement properties of 10 PROMs were evaluated in WAD: Pictorial Fear of Activity Scale-Cervical (PFActS-C), Tampa Scale of Kinesiophobia-11, Pain Catastrophizing Scale (PCS), Pain Self-Efficacy Questionnaire (PSEQ), PSEQ-4 item, PSEQ-2a, PSEQ-2b, Self-Efficacy Scale, Harvard Trauma Questionnaire, and Post-Traumatic Stress Diagnostic Scale. Content validity was not examined in any of these PROMs in whiplash. Moderate- or high-quality evidence showed adequate internal structure for the PSEQ, PCS, and PFActS-C, whereas the original structures of the remaining seven PROMs were not confirmed in whiplash. CONCLUSION: Until further research on the measurement properties of these PROMs is available, researchers may opt to use the PSEQ, PCS, or PFActS-C if the construct is aligned with research aims.

Cervical Motor and Nociceptive Dysfunction After an Acute Whiplash Injury and the Association With Long-Term Non-Recovery: Revisiting a One-Year Prospective Cohort With Ankle Injured Controls.

Aims: To explore the development of cervical motor and nociceptive dysfunction in patients with whiplash (WPs) and non-recovery based on injury-related work disability 1-year after injury when compared with ankle-injured controls (ACs). Methods: A 1-year observational prospective study examining consecutive WPs and age- and sex-matched ACs at 1 week,3 months, 6 months, and 1 year post-injury using semi-structured interviews; global pain rating (VAS0-10) and the pain rating index (PRI-T) and number-of-words-chosen (NWC) from the McGill Pain Questionnaire; examining nociceptive functioning using the cold pressor test (CPT), pressure algometry, and methodic palpation, and central pain processing using counter-stimulation; and examining motor functioning by active cervical range-of-motion (CROM), and neck strength [maximal voluntary contraction flexion/extension (MVC)]. One-year work disability/non-recovery was determined using a semi-structured interview. Results: A total of 141 WPs and 40 ACs were included. Total pain rating index (PRI-T) NWC were higher in ACs after 1 week but higher in WPs after 3 months, 6 months, and 1 year. Ongoing global pain was higher in WPs after 1 week and after 3 and 6 months but not after 1 year. Pressure pain thresholds were reduced, and palpation was higher in the neck and jaw in WPs after 1 week but was not consistently different afterward from ACs. Cervical mobility was reduced in WPs after 1 week, 3 months, and 6 months but not after 1 year, and MVC was significantly reduced in WPs when compared with ACs after 1 week and 1 year but not after 3 and 6 months. One-year non-recovery was only encountered in 11 WPs and not in the AC group. Non-recovered WPs (N-WPs) had consistently significantly higher VAS0-10, PRI-T, NWC, reduced pressure pain thresholds, raised muscle-tenderness, reduced active cervical range-of-motion, reduced active-neck-flexion/extension, and reported higher neck disability scores than recovered WPs. Of special interest, there was increasing tenderness in trigeminal-derived muscles based on palpation scores, and marked reduction of PPDT was most pronounced in N-WPs when compared with recovered WPs and ACs. Conclusion: Cervical motor dysfunction and segmental nociceptive sensitization were present from early after injury in WPs and prolonged in N-WPs. Differences in trigeminal and cervical motor and sensory function in N-WPs could be of interest for future treatment studies.

Trauma-focused cognitive behavioural therapy and exercise for chronic whiplash with comorbid posttraumatic stress disorder: a randomised controlled trial.

ABSTRACT: Many people with chronic whiplash-associated disorders (WAD) have also symptoms of posttraumatic stress disorder (PTSD), but this is rarely considered in usual predominantly exercise-based interventions. We aimed to investigate the effectiveness of combined trauma-focused cognitive behavioural therapy (TF-CBT) and exercise compared with supportive therapy (ST) and exercise for people with chronic WAD and PTSD. A randomised controlled multicentre trial with concealed allocation, assessor blinding, and blinded analysis was conducted. One hundred three participants with chronic WAD (>3 months and <5 years, grade II) and PTSD were randomised to TF-CBT and exercise (n = 53) or ST and exercise (n = 50). Both interventions comprised 10 weeks of TF-CBT or ST, followed by 6 weeks of exercise. Outcomes were measured at baseline, 10, 16 weeks, 6, and 12 months after randomisation. Analysis was intention to treat using linear mixed models. There was no difference between the interventions on the primary outcome of neck pain-related disability at any time point. At 16 weeks, the treatment effect on the 0 to 100 Neck Disability Index was 0.59 (95% confidence interval [CI] 5.51 to -4.33), at 6 months 1.18 (95% CI 6.15 to -3.78), and at 12 months 1.85 (95% CI 6.81 to -3.11). In addition, there was no difference between the interventions for most secondary outcomes at any time. Exceptions were in favour of TF-CBT and exercise, where improvements in PTSD symptoms were found at 16 weeks. From 16 weeks onwards, both groups achieved a clinically important improvement in neck pain-related disability. However, both groups remained moderately disabled.

The role of posttraumatic stress symptoms on chronic pain outcomes in chronic pain patients referred to rehabilitation.

OBJECTIVES: Posttraumatic stress symptoms (PTSS) are highly prevalent in chronic pain patients and may affect pain symptomatology negatively, but there is still a great need to explore exactly how this occurs. Therefore, this study investigated differences in pain intensity, pain-related disability, and psychological distress between chronic pain patients not exposed to a trauma, patients exposed to a trauma with no PTSS, and patients exposed to a trauma with PTSS. Moreover, the moderating effects of PTSS on the associations between pain intensity and pain-related disability and psychological distress were investigated. METHODS: In this cross-sectional cohort study, data were consecutively collected over the course of a year in patients with chronic non-malignant pain referred for multidisciplinary pain rehabilitation at a Danish university hospital pain center using questionnaires assessing pain, pain-related disability, PTSS, anxiety, and depression. RESULTS: The final sample consisted of 682 chronic pain patients, who were divided into three subgroups (no trauma, 40.6%; trauma/no PTSS, 40.5%; trauma/PTSS, 18.9%). Chronic pain patients with PTSS reported significantly higher levels of pain intensity, pain-related disability, depression, and anxiety compared to chronic pain patients without a trauma and chronic pain patients without PTSS. Moreover, PTSS significantly moderated the associations between pain intensity and pain-related psychosocial disability, depression, and anxiety. CONCLUSION: These results highlight the importance of assessing PTSS in chronic pain patients and suggest that PTSS have a specific influence on the association between pain intensity and more psychosocial aspects of the pain condition.

Do post-traumatic pain and post-traumatic stress symptomatology mutually maintain each other? A systematic review of cross-lagged studies.

After traumatic exposure, individuals are at risk of developing symptoms of both pain and post-traumatic stress disorder (PTSD). Theory and research suggest a complex and potentially mutually maintaining relationship between these symptomatologies. However, findings are inconsistent and the applied methods are not always well suited for testing mutual maintenance. Cross-lagged designs can provide valuable insights into such temporal associations, but there is a need for a systematic review to assist clinicians and researchers in understanding the nature of the relationship. Thus, the aim of this systematic review was to identify, critically appraise, and synthesize results from cross-lagged studies on pain and PTSD symptomatology to assess the evidence for longitudinal reciprocity and potential mediators. Systematic searches resulted in 7 eligible studies that were deemed of acceptable quality with moderate risk of bias using the cohort study checklist from Scottish Intercollegiate Guidelines Network. Furthermore, synthesis of significant pathways in the cross-lagged models showed inconsistent evidence of both bidirectional and unidirectional interaction patterns between pain and PTSD symptomatology across time, hence not uniformly supporting the theoretical framework of mutual maintenance. In addition, the synthesis suggested that hyperarousal and intrusion symptoms may be of particular importance in these cross-lagged relationships, while there was inconclusive evidence of catastrophizing as a mediator. In conclusion, the findings suggest an entangled, but not necessarily mutually maintaining relationship between pain and PTSD symptomatology. However, major variations in findings and methodologies complicated synthesis, prompting careful interpretation and heightening the likelihood that future high-quality studies will change these conclusions.

The impact of attachment insecurity on pain and pain behaviors in experimental pain.

OBJECTIVES: Pain perception and pain behaviors are distinct phenomena with different functions. Pain behaviors are protective in their functions, which include eliciting empathy or caring behaviors from others. Moreover, pain behaviors are intertwined with interpersonal relationships with significant others, which is why attachment orientations have been suggested as interpersonal schemas moderating the association between pain and pain behaviors. The aim of the current study was to assess the impact of insecure attachment dimensions on pain behaviors in laboratory-induced pain. METHODS: This experimental study included a sample of 60 patients with low back pain recruited from a large spine center in a hospital in Region of Southern Denmark. Patients were recorded on video during a cold pressor procedure and asked to rate their level of pain. Prior to the procedure, attachment orientations were assessed by the Revised Adult Attachment Scale. Two assessors independently coded the recorded video material for protective and communicative pain behaviors. RESULTS: A positive correlation of moderate size was found between pain intensity and pain communication. As hypothesized, attachment anxiety moderated the association between pain and pain behaviors. A high level of attachment anxiety was associated with at weaker association between pain and pain behaviors. None of the attachment dimensions correlated with pain intensity or pain behaviors. CONCLUSION: The results indicate that patients with high levels of attachment anxiety may downplay pain and communication thereof. This finding is of potential clinical importance, since pain communication, among others, serves the function of eliciting caring behavior from healthcare personnel.
