Interdisciplinary Pain Treatment Research Articles

Broadening the scope of paediatric intensive interdisciplinary pain treatment to promote future resilience and psychological flexibility.

This journal recently published a paper by Wager and colleagues, entitled "Long-term outcomes of children with severe chronic pain: Comparison of former patients with a community sample" (Wager et al., in press). This paper demonstrates the lasting positive effects of intensive interdisciplinary pain treatment (IIPT) in children, and adds confidence in the duration of treatment effects through its unprecedented, controlled, 7-year follow-up design. Youth treated in IIPT are those with the most impairing pain; thus, these results are particularly encouraging, with almost 60% of the clinical sample no longer experiencing chronic pain.

Improvements in Sleep Correlate With Improvements in Clinical Outcomes Among Adolescents Undergoing Intensive Interdisciplinary Pain Treatment.

Intensive interdisciplinary pain treatment (IIPT) programs have been shown to restore function, improve coping, and reduce pain in adolescents with chronic pain. Yet, little is known about patients' sleep during IIPT and whether or not improvements in pain treatment outcomes are associated with changes in sleep pre-to-post IIPT treatment. The objectives of the current study were to describe sleep among adolescents entering IIPT and examine associations between sleep parameters and IIPT treatment effects. Self-reported sleep measures and clinical outcomes (eg, functional disability, coping, average pain), were collected from 44 adolescents (mean age=14.57, 68.2% female) at admission and discharge from an inpatient IIPT program. Wrist-worn actigraphy data and sleep diaries from participants' first week and last week in the program were analyzed to characterize sleep parameters. Participants self-reported poor sleep/wake patterns, high levels of insomnia symptoms, and subclinical problems with daytime sleepiness upon admission into IIPT, although actigraphic indices of sleep from the first week of IIPT admission were only just under clinical guidelines for healthy adolescent sleep. Better self-reported sleep quality assessed via aggregated sleep diaries from the first week was associated with improvement in average pain and disability over the course of the program. Furthermore, improvements in insomnia symptoms and daytime sleepiness throughout the program were positively correlated with concurrent improvements in functional disability and coping. Taken together, results suggest that sleep may be associated with IIPT treatment effects and pave the way for future research to continue examining these relationships.

Short-Term and Long-Term Effectiveness of Intensive Interdisciplinary Pain Treatment for Children and Adolescents with Chronic Headache: A Longitudinal Observation Study.

Pediatric chronic headache causes significant impairment to those affected and bears the risk of aggravation into adulthood. Intensive interdisciplinary pain treatment (IIPT) was found to positively affect pain-related and emotional outcomes in pediatric patients with chronic pain up to 4 years after treatment. This study was aimed at investigating the effect of IIPT on solely pediatric chronic headache patients. As part of a longitudinal observation study, n = 70 children and adolescents with chronic headache receiving IIPT were included, of which n = 47 completed the assessment at four assessment time points: before treatment (PRE) and at three follow-ups (6-MONTH FOLLOW-UP, 1-YEAR FOLLOW-UP, and 4-YEAR FOLLOW-UP). Pain-related (pain intensity, pain-related disability, school absence), as well as psychological outcome domains (anxiety, depression), were investigated. The results support the short-term and long-term efficacy of IIPT for pediatric chronic headache patients regarding the pain-related outcome measures by significant reductions from PRE to all follow-up measure points. For anxiety and depression, only short-term improvements were found. Future studies should specifically focus on the identification of methods to consolidate the beneficial short-term effects of IIPT on psychological outcome domains in the long term.

A Network Analysis of Clinical Variables in Chronic Pain: A Study from the Swedish Quality Registry for Pain Rehabilitation (SQRP).

Efforts to identify specific variables that impact most on outcomes from interdisciplinary pain rehabilitation are challenged by the complexity of chronic pain. Methods to manage this complexity are needed. The purpose of the study was to determine the network structure entailed in a set of self-reported variables, examine change, and look at potential predictors of outcome, from a network perspective. In this study we apply network analysis to a large sample of people seeking interdisciplinary pain treatment (N = 2,241). Variables analyzed include pain intensity, pain interference, extent of pain, depression, anxiety, insomnia, and psychological variables from cognitive behavioral models of chronic pain. We found that Acceptance, Pain Interference, and Depression were key, "central," variables in the pretreatment network. Interestingly, there were few changes in the overall network configuration following treatment, specifically with respect to which variables appear most central relative to each other. On the other hand, Catastrophizing, Depression, Anxiety, and Pain Interference each became less central over time. Changes in Life Control, Acceptance, and Anxiety were most strongly related to changes in the remainder of the network as a whole. Finally, no network differences were found between treatment responders and non-responders. This study highlights potential future targets for pain treatment. Further application of a network approach to interdisciplinary pain rehabilitation data is recommended. Going forward, it may be better to next do this in a more comprehensive theoretically guided fashion, and ideographically, to detect unique individual differences in potential treatment processes.

Long-term outcomes of children with severe chronic pain: Comparison of former patients with a community sample.

Findings on the short- and long-term effectiveness of intensive interdisciplinary pain treatment (IIPT) for children with severe chronic functional pain are promising. However, a definitive appraisal of long-term effectiveness cannot be made due to a lack of comparison groups. The aim of the present study was to compare the health status of former patients with the health status of an age- and sex-matched comparison group from the community. Data from two samples, a clinical sample of former patients (n=162; aged 14 to 26) and an age- and sex-matched community sample (n=162), were analysed. Former patients provided data 7years after IIPT. Pain characteristics, physical and mental health status, autonomy, coping and health care utilisation were compared between the two samples. Seven years after treatment, the majority (58%) of the clinical sample were completely pain-free. Compared to the community sample, the clinical sample demonstrated worse physical and mental health and continued to seek more frequent health care, irrespective of whether or not they experienced ongoing chronic pain. However, the clinical sample reported better coping strategies and a comparable level of autonomy. Patients experiencing severe chronic pain in childhood who engage in IIPT are likely to have recovered from their pain in early adulthood. Long-term treatment effects may manifest in better coping strategies. However, reduced mental and physical health status may indicate a negative long-term effect of early chronic pain experiences or a general vulnerability in people developing a chronic pain condition in childhood. The majority of severely impaired paediatric chronic pain patients no longer suffer from chronic pain seven years after intensive interdisciplinary pain treatment. However, former patients have worse physical and mental health status than a community sample, and continue to seek out more frequent health care utilisation, irrespective of whether or not they continue to experience chronic pain. Therefore, potential negative long-term effects of childhood chronic pain experiences need specific attention early on.

Sleep among Youth with Severely Disabling Chronic Pain: Before, during, and after Inpatient Intensive Interdisciplinary Pain Treatment.

Poor sleep is commonly reported in pediatric chronic pain. There are signals that intensive interdisciplinary pain treatments (IIPT) may inadvertently improve objective sleep, but this claim cannot be substantiated without baseline sleep data prior to IIPT. This study followed the objective sleep/wake patterns (e.g., duration, quality, timing, consistency) of pediatric patients with severely functionally disabling chronic pain before, during, and after inpatient IIPT (the Functional Independence Restoration Program—“FIRST Program”), alongside a similarly-disabled chronic pain Comparison Group. The final sample included N = 10 FIRST Patients and N = 9 Comparison Group patients. At baseline, the whole sample showed healthy sleep duration (~9 h), average sleep efficiency <90%, late sleep onset and offset (mean = 11:56 p.m.–8:50 a.m.), and highly inconsistent sleep schedules night to night. During IIPT, FIRST Patients maintained healthy sleep durations, moved sleep schedules 2 h earlier, and decreased timing and duration variability by >60 min while the Comparison Group maintained similar sleep to baseline. At follow up (1–2 months later), FIRST Patients’ sleep schedules shifted later but were still less variable than at baseline. Results point to the malleability of sleep/wake patterns within treatment contexts with strict environmental control but suggest that these gains may be difficult for youth with chronic pain to maintain in the home environment.

Youth and parent perceptions on participating in specialized multidisciplinary pain rehabilitation options: A qualitative timeline effect analysis

ABSTRACT Background: Little is known about how the specialized treatment journey is perceived by youth with pain-related disability and their parents. Aims: Describe and compare the treatment effects and outcomes as perceived by youth and their parents enrolled in intensive interdisciplinary pain treatment (IIPT) or multimodal treatment (MMT). Methods: Eleven IIPT youth and five parents and three MMT youth and five parents were recruited. All were asked to complete a treatment journey timeline, followed by separately conducted semistructured interviews. Transcribed interviews were analyzed using reflective thematic analysis. Results: The main themes spanned the treatment trajectory. All participants described similar initial struggles (Theme 1). Positive and negative treatment effects associated with acquisitions and disruptions (Theme 2), and outcomes post-discharge related to supports and realities (Theme 3) emerged. Knowledge, skills, and support acquisition during treatment and feeling empowered and confident to self-manage postdischarge were identified as IIPT benefits. However, the change effort and life disruptions required and the difficulty transitioning to real life postprogram were acknowledged as detrimental IIPT impacts. Continuing with life as usual and maintaining supports in daily contexts (e.g., school personnel, friends) were reported MMT benefits. However, the challenges of managing pain, treatment adherence within the competing demands of daily realities, and the lack of support to integrate strategies were emphasized as detrimental MMT impacts. Conclusions: Detailed impacts of two specialized multidisciplinary pain rehabilitation interventions on the lives of youth with pain-related disability and their parents are described. The treatments benefits and previously unexplored detrimental effects are unveiled.

Exploring the Feasibility of Relapse Prevention Strategies in Interdisciplinary Multimodal Pain Therapy Programs: Qualitative Study.

BackgroundAlthough interdisciplinary multimodal pain treatment (IMPT) programs are widely regarded as treatment of choice for patients with chronic pain, there are signs that many patients are unable to maintain their treatment gains in the long term. To facilitate the maintenance of positive treatment outcomes over time, we developed two relapse prevention strategies.ObjectiveThe main objective of this study was to explore the feasibility of these strategies within the context of IMPT programs.MethodsWe performed a feasibility study using 3 workbook prototypes containing either one or both strategies. For a period of 6 months, the workbooks were made available in two IMPT facilities. Qualitative data were collected through a focus group and semistructured interviews. We performed a thematic analysis using a deductive approach with (1) applicability to the treatment program, (2) acceptability of the workbook content, and (3) form, as predefined themes.ResultsThe final dataset consisted of transcripts from a focus group with health care providers and 11 telephone interviews and 2 additional in-depth interviews with patients. In general, the intervention was perceived as useful, easy to use, and in line with the treatment program. The data also include suggestions to further improve the use of both strategies, including more specific implementation guidelines, revised goal-setting procedure, and development of a mobile health version. However, several factors, including a high dropout rate and small sample size, impact the external validity of our findings.ConclusionsThis study should be regarded as a first step in the process of transforming the prototype workbook into an effective intervention for clinical practice. Although these initial results indicate a favorable evaluation of both behavior regulation strategies within the workbook, this study encountered multiple barriers regarding implementation and data collection that limit the generalizability of these results. Future research efforts should specifically address the fidelity of HCPs and patients and should include clear procedures regarding recruitment and use of both relapse prevention strategies during treatment.

Therapeutic Drug Monitoring of Antidepressants for the Treatment of Chronic Musculoskeletal Pain With and Without Depression.

Antidepressants are recommended for the treatment of chronic musculoskeletal pain; however, target serum concentrations based on therapeutic drug monitoring (TDM) have not been established. Therefore, the authors analyzed routine care TDM data of antidepressants in patients with chronic pain with and without depression in terms of treatment outcomes in an interdisciplinary multimodal pain treatment (IMPT) program. Patients with chronic musculoskeletal pain and TDM for amitriptyline (n = 45) or duloxetine (n = 30) were retrospectively included. The German pain questionnaire for pain intensity and the Depression Anxiety Stress scale were applied at T0 and at the end of the IMPT program (T1). A relief of pain intensity score ≥2 was considered as a positive outcome. Comorbid depression was diagnosed based on ICD-10 criteria. Serum concentrations of antidepressants were measured for routine clinical care TDM. After IMPT, stress improved in all subgroups, and depressive symptoms improved only in the duloxetine group. Overall, 40% and 27% of patients in the amitriptyline and duloxetine subgroup, respectively, were responders in terms of maximum pain score relief. Responders with comorbid depression were treated with a dose that led to a 1.7-fold higher serum concentration of the active moiety of amitriptyline (amitriptyline + nortriptyline) compared with nonresponders. Similarly, a 2.3-fold higher serum concentration was observed in depressed responders than in nondepressed responders (at minimum 131.5 ng/mL). Dosing of antidepressants for chronic pain relief should specifically take comorbid depression into account. TDM may provide better outcomes of pain relief in an IMPT setting in patients with comorbid depression.

Virtual Reality in Pain Rehabilitation for Youth With Chronic Pain: Pilot Feasibility Study.

BackgroundIn the field of pain, virtual reality (VR) technology has been increasingly common in the context of procedural pain management. As an interactive technology tool, VR has the potential to be extended beyond acute pain management to chronic pain rehabilitation with a focus on increasing engagement with painful or avoided movements.ObjectiveWe outline the development and initial implementation of a VR program in pain rehabilitation intervention to enhance function in youth with chronic pain.MethodsWe present the development, acceptability, feasibility, and utility of an innovative VR program (Fruity Feet) for pediatric pain rehabilitation to facilitate increased upper and lower extremity engagement. The development team was an interdisciplinary group of pediatric experts, including physical therapists, occupational therapists, pain psychologists, anesthesiologists, pain researchers, and a VR software developer. We used a 4-phase iterative development process that engaged clinicians, parents, and patients via interviews and standardized questionnaires.ResultsThis study included 17 pediatric patients (13 female, 4 male) enrolled in an intensive interdisciplinary pain treatment (IIPT) program, with mean age of 13.24 (range 7-17) years, completing a total of 63 VR sessions. Overall reports of presence were high (mean 28.98; max 40; SD 4.02), suggestive of a high level of immersion. Among those with multisession data (n=8), reports of pain (P<.001), fear (P=.003), avoidance (P=.004), and functional limitations (P=.01) significantly decreased. Qualitative analysis revealed (1) a positive experience with VR (eg, enjoyed VR, would like to utilize the VR program again, felt VR was a helpful tool); (2) feeling distracted from pain while engaged in VR; (3) greater perceived mobility; and (4) fewer clinician-observed pain behaviors during VR. Movement data support the targeted impact of the Fruity Feet compared to other available VR programs.ConclusionsThe iterative development process yielded a highly engaging and feasible VR program based on qualitative feedback, questionnaires, and movement data. We discuss next steps for the refinement, implementation, and assessment of impact of VR on chronic pain rehabilitation. VR holds great promise as a tool to facilitate therapeutic gains in chronic pain rehabilitation in a manner that is highly reinforcing and fun.

Which passengers are on your bus? A taxonomy of the barriers adolescents with chronic pain face in achieving functional recovery.

Despite evidence that intensive interdisciplinary pain treatment (IIPT) is effective in facilitating functional recovery in adolescents with chronic pain, engagement with IIPT is suboptimal among adolescents. A key aspect of IIPT is to support functional recovery via (re)engagement with age-appropriate daily activities. The aim of this study was to gain a comprehensive insight into adolescents' perceptions of the barriers they need to overcome to engage with age-appropriate activities in order to achieve functional recovery. Forty-one adolescents who were starting an IIPT programme completed the 'passenger-on-the-bus metaphor', an exercise in which they identify and describe their perceived barriers (i.e. 'passengers' on their bus) that prevent them from engaging with age-appropriate activities. The responses were analysed using inductive thematic analyses to generate a taxonomy of perceived barriers to functional recovery. We generated a taxonomy of seven different barriers that participants described facing on their road to functional recovery: physical constraints, being 'fed up', low self-confidence and self-esteem, perfectionism, avoidance of engagement with pain, feelings (such as sadness, anger, guilt, anxiety) and social barriers (received from a range of sources such as parents, friends, school and wider society). The findings reveal a variety of barriers that were perceived to hinder functional recovery through reduced engagement with age-appropriate activities and thereby hamper progress within IIPT. The Passenger on the bus metaphor can be used to identify similar barriers faced by adolescents in an individualized treatment approach, thereby making it possible for clinicians to target their IIPT more precisely.

Mobile Health App (AGRIPPA) to Prevent Relapse After Successful Interdisciplinary Treatment for Patients With Chronic Pain: Protocol for a Randomized Controlled Trial.

BackgroundTo facilitate adherence to adaptive pain management behaviors after interdisciplinary multimodal pain treatment, we developed a mobile health app (AGRIPPA app) that contains two behavior regulation strategies.ObjectiveThe aims of this project are (1) to test the effectiveness of the AGRIPPA app on pain disability; (2) to determine the cost-effectiveness; and (3) to explore the levels of engagement and usability of app users.MethodsWe will perform a multicenter randomized controlled trial with two parallel groups. Within the 12-month inclusion period, we plan to recruit 158 adult patients with chronic pain during the initial stage of their interdisciplinary treatment program in one of the 6 participating centers. Participants will be randomly assigned to the standard treatment condition or to the enhanced treatment condition in which they will receive the AGRIPPA app. Patients will be monitored from the start of the treatment program until 12 months posttreatment. In our primary analysis, we will evaluate the difference over time of pain-related disability between the two conditions. Other outcome measures will include health-related quality of life, illness perceptions, pain self-efficacy, app system usage data, productivity loss, and health care expenses.ResultsThe study was approved by the local Medical Research Ethics Committee in October 2019. As of March 20, 2020, we have recruited 88 patients.ConclusionsThis study will be the first step in systematically evaluating the effectiveness and efficiency of the AGRIPPA app. After 3 years of development and feasibility testing, this formal evaluation will help determine to what extent the app will influence the maintenance of treatment gains over time. The outcomes of this trial will guide future decisions regarding uptake in clinical practice.Trial RegistrationNetherlands Trial Register NL8076; https://www.trialregister.nl/trial/8076International Registered Report Identifier (IRRID)DERR1-10.2196/18632

Is It Worth It? A Comparison of an Intensive Interdisciplinary Pain Treatment and a Multimodal Treatment for Youths With Pain-related Disability.

The objective of this study was to evaluate the effectiveness of an intensive interdisciplinary pain treatment (IIPT) day-hospital program as compared with an outpatient multimodal treatment (MMT) for youth with chronic pain. A nonrandomized pretest posttest with control group design was used. A battery of patient-oriented measures assessing pain interference, quality of life, and depressive symptoms were completed at treatment commencement and at 3, 6, and 12 months after treatment by 44 youths enrolled in the IIPT and 138 youths engaged in the MMT, with various chronic pain conditions. Data were analyzed using longitudinal mixed-effects models. The main outcomes were the score difference from baseline of patient-oriented measures across 3 timepoints within 12 months of intervention initiation for both treatment groups. IIPT participants demonstrated greater improvement in pain interference, as compared with MMT at 3 and 12 months. Initially, health-related quality of life scores improved similarly in both groups, but greater improvement was seen in the MMT group at 12 months. Depressive symptom scores did not improve with either intervention. Only pain interference scores reached statistically and clinically significant difference levels. This study supports the benefits of specialized rehabilitation interventions, including both MMT and IIPT programs, for youths with chronic pain. The findings also suggest that IIPT might have a greater long-term effect for helping youths, in particular those with high pain interference scores.

Putting fitness to the test: clinical application of the Fitkids Treadmill Test in youth with chronic pain

Purpose Examine the clinical utility of the Fitkids Treadmill Test (FTT) for assessing cardiovascular endurance in youth with chronic pain. Materials and methods Fifty-five youth with chronic pain completed the FTT at admission and discharge from intensive interdisciplinary pain treatment (IIPT). Feasibility, construct validity and responsiveness of the FTT were examined retrospectively using a clinical data registry. Results Participants’ FTT time to exhaustion (TTE) improved by 1.5 min after IIPT (95% CI: 1.1–2.0 min), yet remained below age and sex-matched norms. Construct validity was only supported by performance-based assessments of physical function. Evidence of discriminant validity was found, as the FTT was not correlated with unrelated biopsychosocial constructs. Conclusions Youth with chronic pain present with significant deficits in cardiovascular endurance that are not fully reversed after IIPT, highlighting the importance of ongoing aerobic training after discharge. Findings support the FTT as a valid, objective measure of cardiovascular endurance in youth with chronic pain. FTT performance is relatively unencumbered by psychosocial constructs.

Examining the effectiveness of pain rehabilitation on chronic pain and post-traumatic symptoms.

Patients with co-morbid chronic pain and post-traumatic stress disorder (PTSD) pose significant treatment challenges. This study evaluated the effectiveness of an interdisciplinary pain rehabilitation program (IPRP) in improving pain and PTSD outcomes, as well as reducing medication use. In addition, the mediating effect of pain catastrophizing, which is theorized to underlie the pain and PTSD comorbidity, was examined. Participants included 83 completers of an IPRP with chronic pain and a provisional PTSD diagnosis. Significant improvements were found for pain outcomes, PTSD symptomatology, depressive symptoms, physical performance, and medication use (i.e., opioids and benzodiazepines). At discharge, 86.7% of participants reliably improved in at least one key measure of functioning and 50.6% demonstrated reliable improvement in PTSD symptomatology. Change in pain catastrophizing mediated improvements in pain interference and PTSD symptomatology. Results support the potential utility of an interdisciplinary pain treatment approach in the treatment of patients with comorbid pain and PTSD.

Reported Outcomes in Published Systematic Reviews of Interdisciplinary Pain Treatment: Protocol for a Systematic Overview.

BackgroundInterdisciplinary pain treatment (IPT) is a complex intervention; its outcomes are very diverse, as are the methodologies for handling those outcomes. This diversity may hamper evidence-based decision making. Presently, there is no gold standard recommendation of how to select reported outcomes in published systematic reviews and meta-analyses to explicitly demonstrate the effectiveness of IPT.ObjectiveIn this systematic overview, we aim to evaluate the reported outcome domains and measurements across published systematic reviews and meta-analyses and to identify any methods, considerations, and discussion regarding the handling of the chosen outcome domains and measurements.MethodsThis article describes the protocol for a systematic overview of the outcomes reported in published systematic reviews and meta-analyses of randomized control trials for the effectiveness of IPT versus any control. To this end, we searched the PubMed, Cochrane Library, and Epistemonikos databases from inception to December 2019. Two independent investigators screened the titles, the abstracts of the identified records, and the full texts of the potentially eligible systematic reviews and meta-analyses, performed data extraction according to predefined forms, and rated the quality of the included systematic reviews and meta-analyses. The quality of the included systematic reviews and meta-analyses will be rated with AMSTAR (A MeaSurement Tool to Assess systematic Reviews) 2. Data will be analyzed descriptively and stratified by AMSTAR 2.ResultsWe introduced the rationale and design of a systematic overview to summarize and map the chosen IPT outcome domains and the methods of handling these outcomes reported in published systematic reviews and meta-analyses. As of December 2019, we collected 5229 systematic reviews, of which 147 (2.81%) were examined in-depth for eligibility. Topline results are anticipated by September 2020.ConclusionsThe results of this study will be published as soon as they are available. Our results will fill a gap in the related literature and will be used to inform the development of a set of recommendations that can be applied in systematic reviews and hopefully serve as a gold standard.International Registered Report Identifier (IRRID)PRR1-10.2196/17795

Does intensive interdisciplinary pain treatment improve pediatric headache-related disability?

Purpose To examine the effectiveness of intensive interdisciplinary pain treatment for improving disability in children with chronic headache using the International Classification of Functioning, Disability and Health model as a conceptual framework for disability assessment. Materials and methods Children with chronic headache (n = 50; ages 10–19 years; 62% female) attended an intensive interdisciplinary pain treatment program 8 h/day, 5 times/week for 2–7 weeks. Disability measures were administered at admission, discharge, and 6–8 week follow-up. Disability outcomes were analyzed retrospectively. Wilcoxon signed rank tests and Friedman’s analyses of variance were used to compare scores across two and three longitudinal time points, respectively. Results After rehabilitation, disability reduced on the Headache Impact Test-6 from severe impact at admission to some impact at follow-up (p < 0.001). Median time on the modified Bruce protocol increased from 13.1 min (interquartile range = 12.6–14.1) to 14.4 min (interquartile range = 12.9–16.3), p < 0.001, with gains maintained at follow-up. Improvements in pain and disability were associated with improvements in school participation. Conclusions Findings of this study support the effectiveness of intensive interdisciplinary pain treatment for improving disability in children with chronic headache. Implication for rehabilitation Intensive interdisciplinary pain treatment is effective for improving pain and disability in children with chronic headaches. Application of the ICF model to disability assessment suggests that children with chronic headaches may experience significant disability, even when standardized assessments of physical capacity are normal. The modified Bruce protocol, Pediatric Evaluation of Disability Inventory – Computerized Adaptive Tests, and Headache Impact Test-6 appear particularly valuable in understanding the nature of disability in children with chronic headaches.

Readiness to Change Among Adolescents with Chronic Pain and Their Parents: Is the German Version of the Pain Stages of Change Questionnaire a Useful Tool?

The Pain Stages of Change Questionnaire (PSOCQ) measures patients’ willingness to engage in active self-management of their pain. The present study aimed to create validated German short versions of the PSOCQ for adolescents (PSOCQ-A) and their parents (PSOCQ-P). Additionally, an investigation of stages of change regarding pain characteristics and treatment outcomes was undertaken. In Study 1, the data of adolescents aged 11 to 18 years and their parents were collected prior to intake (N = 501) and at admission (N = 240) to specialist inpatient pain treatment. Confirmatory factor analyses indicated a poor fit of the full PSOCQ measures prior to intake, but an acceptable fit at admission. Short PSOCQ-A and PSOCQ-P versions were identified. In Study 2, these results were cross-validated with data from an additional N = 150 patients and their parents, collected during and 3 months after interdisciplinary inpatient pain treatment. Model fits for both short versions were acceptable, although low internal consistency for the PSOCQ-A Precontemplation and Contemplation subscales was identified. During treatment, both patients’ and their parents’ readiness to change increased. Stage of change at discharge did not predict treatment non-response 3 months later. This study indicates that the PSOCQ is neither meaningful prior to admission nor predictive of non-response to treatment. While some value may exist in monitoring treatment progress, based on the results of this study, it is not recommended that the PSOCQ-A and PSOCQ-P be used as a measure of stage of change in German pediatric pain populations.

Posttraumatic stress disorder in children and adolescents with chronic pain.

Despite high comorbidity between posttraumatic stress disorder (PTSD) and chronic pain evident in adult populations, little research has been conducted in the pediatric population to assess this association. Therefore, this study aimed to estimate the prevalence of trauma and PTSD in pediatric patients with chronic pain. Additionally, investigation into whether the Child Report of Posttraumatic Symptoms (CROPS) is a valid PTSD screening tool for this patient population and identification of an appropriate clinical cutoff for screening PTSD was undertaken. Data of N = 297 children and adolescents aged 8 to 17 years were collected during an intensive interdisciplinary pain treatment. At admission, patients self-reported pain characteristics and posttraumatic stress symptoms (assessed with the CROPS). During the inpatient stay, therapists completed a checklist that enabled a PTSD diagnosis according to criteria of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Overall, 18.2% of the patients reported a trauma that met criterion A of DSM-5. Of those patients, approximately 59.3% had a PTSD diagnosis, equivalent to 10.8% of the whole sample. Overall, the CROPS demonstrated good reliability and validity in terms of internal consistency, item characteristics, and factor structure. Patients with PTSD had higher CROPS scores than patients without trauma. To identify patients with PTSD, a CROPS cutoff point of 21 is most appropriate in this population. This study demonstrated high prevalence of PTSD in children and adolescents with severe chronic pain. Regarding PTSD screening in this population, results revealed that valid PTSD assessment and identification of patients with PTSD seems possible despite overlapping symptoms.

Using collaborative logic analysis evaluation to test the program theory of an intensive interdisciplinary pain treatment for youth with pain‐related disability

Intensive interdisciplinary pain treatment (IIPT) involves multiple stakeholders. Mapping the program components to its anticipated outcomes (ie, its theory) can be difficult and requires stakeholder engagement. Evidence is lacking, however, on how best to engage them. Logic analysis, a theory‐based evaluation, that tests the coherence of a program theory using scientific evidence and experiential knowledge may hold some promise. Its use is rare in pediatric pain interventions, and few methodological details are available. This article provides a description of a collaborative logic analysis methodology used to test the theoretical plausibility of an IIPT designed for youth with pain‐related disability. A 3‐step direct logic analysis process was used. A 13‐member expert panel, composed of clinicians, teachers, managers, youth with pain‐related disability, and their parents, were engaged in each step. First, a logic model was constructed through document analysis, expert panel surveys, and focus‐group discussions. Then, a scoping review, focused on pediatric self‐management, building self‐efficacy, and fostering participation, helped create a conceptual framework. An examination of the logic model against the conceptual framework by the expert panel followed, and recommendations were formulated. Overall, the collaborative logic analysis process helped raiseawareness of clinicians’ assumptions about the program causal mechanisms, identified program components most valued by youth and their parents, recognized the program features supported by scientific and experiential knowledge, detected gaps, and highlighted emerging trends. In addition to providing a consumer‐focused program evaluation option, collaborative logic analysis methodology holds promise as a strategy to engage stakeholders and to translate pediatric pain rehabilitation evaluation research knowledge to key stakeholders.
