Psychology

Social and interpersonal factors impact the trajectory of chronic pain. We previously developed and validated a 2-factor, 7-item measure to assess interpersonal factors, including relationship guilt and worry and difficulty prioritizing self-care in chronic pain. Here, we confirm the factor structure and examine the sex invariance of the two-factor structure of the CARE Scale-7.

Chronic low back pain (CLBP) is a major cause of global disability and improving management is essential. Acceptance and Commitment Therapy (ACT) is a promising treatment for chronic pain but has not been modified for physical therapy. This randomized controlled trial (RCT) compared physical therapy informed by Acceptance and Commitment Therapy (PACT) against standard care physical therapy for patients with CLBP. Patients with CLBP (duration ≥12 weeks, mean 3 years) were recruited from physical therapy clinics in four UK public hospitals. The Roland-Morris Disability Questionnaire (RMDQ) at 3 months' post randomization was the primary outcome. 248 participants (59% female, mean age=48) were recruited and 219 (88•3%) completed measures at 3 and/or 12 months' follow-up. At 3 months, PACT participants reported better outcomes for disability (RMDQ mean difference =1•07, p=0•037, 95%CI -2•08 to -0•07, d=0•2), Patient Specific Functioning (p=0.008), SF12 physical health (p=0.032), and treatment credibility (p<0.001). At 12 months' follow-up there were no significant differences between groups. PACT was acceptable to patients and clinicians and feasible to deliver. Physical therapists incorporated psychological principles successfully and treatment was delivered with high (≥80%) fidelity. Our results may inform the management of CLBP, with potential benefits for patients, health care providers and society. PERSPECTIVE: Psychologically informed physical therapy has great potential but there are challenges in implementation. The training and support included in the PACT trial enabled the intervention to be delivered as planned. This successfully reduced disability in the short but not long term. Findings could inform physical therapists' treatment of CLBP.

Daily fluctuation in pain acceptance and its impact on the physical and psychosocial functioning of individuals living with spinal cord injury (SCI) and chronic pain has not been examined. We used end-of-day (EOD) diaries and multilevel mixed effects modeling (MLM) to examine the moderating effect of within- and between-person pain acceptance on associations between pain and physical and psychosocial functioning. Individuals with SCI and chronic pain (N = 124) completed seven days of EOD diaries, which included measures of pain acceptance, pain intensity, pain catastrophizing, pain interference, participation in social roles and activities (SRA), depressive symptoms, and positive affect and well-being (PAWB). We found within-person variability in pain acceptance (28% of the total variance) and a significant moderating effect of daily fluctuation in pain acceptance on the same-day pain intensity-SRA association. Within-person changes in pain acceptance were also associated with daily changes in pain interference, depressive symptoms, and PAWB, adjusting for pain intensity and catastrophizing. Findings highlight the potential for daily or momentary assessments of pain acceptance to enhance understanding of how psychological flexibility may contribute to pain-related outcomes. Future studies could further investigate stable and variable characteristics of pain acceptance and their individual contribution to physical and psychosocial functioning. PERSPECTIVE: Daily fluctuations in pain acceptance and their association with physical and psychosocial functioning were observed in the lives of individuals with spinal cord injury (SCI) and chronic pain. These findings may guide future studies to inform the development of effective, pain acceptance-focused individualized treatment approaches for chronic pain management in people with SCI.

Opioid prescription in the treatment of chronic pain is frequent and carries a risk of increased morbidity and mortality in a clinically significant number of patients, particularly those who are using opioids in a hazardous manner. Few treatment options are available that target both pain-related interference and hazardous opioid use among patients with chronic pain. In military Veterans, this issue is of particular importance as numerous reports indicate continued high rates of opioid prescription for chronic pain, as well as significant opioid-related problems. The overall aim of the present study was to determine the feasibility of an integrated psychosocial treatment in Veterans with chronic pain, who also have evidence of hazardous opioid use. To examine this aim, a random design was used to assess the feasibility and initial efficacy of integrating two empirically supported interventions: Acceptance and Commitment Therapy for chronic pain and Mindfulness Based Relapse Prevention for opioid misuse. Half of participants were randomized to the integrated treatment group and all participants received usual care (UC) through a Veteran's Administration co-occurring disorders medical clinic to treat chronic pain and opioid misuse. In total, 37 participants were randomized and included in intent to treat (ITT) analyses and 32 individuals were included in per protocol (PP) analyses with 6-month follow-up serving as the primary study endpoint. Feasibility indicators included recruitment, retention, and treatment completion rates. Recruitment fell short of targeted enrollment, although retention and completion were excellent. Primary outcome measures were opioid misuse, pain interference, and pain behavior. Simultaneous multiple regression analyses controlled for pain duration, baseline opioid dose, and baseline value for outcome measures. Results of both the ITT and PP indicated a significant effect in favor of the integrated intervention for opioid misuse, pain interference, and pain behavior. Results support the feasibility of providing an integrated treatment for both opioid risk and pain interference. PERSPECTIVE: Opioid misuse occurs in some opioid-prescribed individuals with chronic pain. Few treatment options exist that target both pain interference and opioid misuse. This study examined feasibility and initial efficacy of an integrated behavioral treatment for Veterans. Feasibility was supported, except recruitment. Efficacy was supported compared to usual care.

To investigate prognostic factors for physical and emotional functioning following interdisciplinary multimodal pain rehabilitation, by targeting patients' baseline characteristics and health measures.

Women remain underrepresented on faculties of medicine and the life sciences more broadly. Whether gender differences in self presentation of clinical research exist and may contribute to this gender gap has been challenging to explore empirically. The objective of this study was to analyze whether men and women differ in how positively they frame their research findings and to analyze whether the positive framing of research is associated with higher downstream citations.
