The actometer: an evaluation of instrument applicability for chronic pain patients
Three experiments were conducted to determine the reliability and validity of an activity measurement device, the actometer, as an index of ambulation for chronic pain patients. In experiment I, correlations between yoked actometers during ambulation showed the instrument to be internally reliable. In experiment II, actometer readings covaried very strongly with distance, showing the device to be valid during single trial assessment. However, experiment III found the device to show poor reliability over time (i.e., substantial measurement variability for the identical distance on 3 separate days). The results suggest that, for the chronic pain population, the actometer may not be a useful instrument for reliably assessing changes in walking activity over time.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27387/1/0000418.pd

Pain Coping Skills Training for Patients Who Catastrophize About Pain Prior to Knee Arthroplasty: A Multisite Randomized Clinical Trial
BACKGROUND:
Pain catastrophizing has been identified as a prognostic indicator of poor outcome following knee arthroplasty. Interventions to address pain catastrophizing, to our knowledge, have not been tested in patients undergoing knee arthroplasty. The purpose of this study was to determine whether pain coping skills training in persons with moderate to high pain catastrophizing undergoing knee arthroplasty improves outcomes 12 months postoperatively compared with usual care or arthritis education.
METHODS:
A multicenter, 3-arm, single-blinded, randomized comparative effectiveness trial was performed involving 5 university-based medical centers in the United States. There were 402 randomized participants. The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Scale, measured at baseline, 2 months, 6 months, and 12 months following the surgical procedure.
RESULTS:
Participants were recruited from January 2013 to June 2016. In 402 participants, 66% were women and the mean age of the participants (and standard deviation) was 63.2 ± 8.0 years. Three hundred and forty-six participants (90% of those who underwent a surgical procedure) completed a 12-month follow-up. All 3 treatment groups had large improvements in 12-month WOMAC pain scores with no significant differences (p > 0.05) among the 3 treatment arms. No differences were found between WOMAC pain scores at 12 months for the pain coping skills and arthritis education groups (adjusted mean difference, 0.3 [95% confidence interval (CI), -0.9 to 1.5]) or between the pain coping and usual-care groups (adjusted mean difference, 0.4 [95% CI, -0.7 to 1.5]). Secondary outcomes also showed no significant differences (p > 0.05) among the 3 groups.
CONCLUSIONS:
Among adults with pain catastrophizing undergoing knee arthroplasty, cognitive behaviorally based pain coping skills training did not confer pain or functional benefit beyond the large improvements achieved with usual surgical and postoperative care. Future research should develop interventions for the approximately 20% of patients undergoing knee arthroplasty who experience persistent function-limiting pain.

Meeting them where they are: Using the Internet to deliver behavioral medicine interventions for pain
Pharmacological and interventional pain medicine treatments are emphasized in the routine treatment of chronic pain despite strong evidence for the efficacy and safety of behavioral approaches. Most medical professionals have not incorporated behavioral pain treatments into their practices. Internet-based interventions have the potential to increase clinical use of these treatments. We discuss the strengths and weaknesses of current Internet-based behavioral pain management interventions, focusing on three broad intervention categories: therapist-guided interventions, unguided (automated) interventions, and pain-relevant applications for mobile platforms. Examples of each category are discussed, revealing a high degree of variation in approaches, user interfaces, and components as well as variability in the degree to which these interventions have been subjected to empirical testing. Finally, we highlight key issues for research and clinical implementation, with the goal of advancing this field so that it can meet its potential to increase access to evidence-based behavioral medicine treatments for chronic pain

Domain Specific Self-Efficacy Mediates the Impact of Pain Catastrophizing on Pain and Disability in Overweight and Obese Osteoarthritis Patients
This study examined whether self-efficacy mediated the relationship between pain catastrophizing and pain and disability. Participants were 192 individuals diagnosed with osteoarthritis (OA) of the knees who were overweight or obese. Multiple mediator analyses were conducted to simultaneously test self-efficacy for pain control, physical function, and emotional symptoms as mediators while controlling for demographic and medical status variables. Higher pain catastrophizing was associated with lower self-efficacy in all three domains (ps< .05). Self-efficacy for pain control fully mediated the relationship between pain catastrophizing and pain (Beta=.08, Sobel test Z=1.97, p<.05). The relationship between pain catastrophizing and physical disability was fully mediated by self-efficacy for physical function (Beta=.06, Sobel test Z=1.95, p=.05). Self-efficacy for emotional symptoms partially mediated the relationship between pain catastrophizing and psychological disability (Beta=. 12, Sobel test Z=2.92, p<.05). These results indicate that higher pain catastrophizing contributed to greater pain and disability via lower domain-specific self-efficacy. Efforts to reduce pain and improve functioning in OA patients should consider addressing pain catastrophizing and domain specific selfefficacy. Pain catastrophizing may be addressed through cognitive therapy techniques and selfefficacy may be enhanced through practice of relevant skills and personal accomplishments. Perspective- This paper found that higher pain catastrophizing contributed to great pain and disability via domain specific self-efficacy. These results suggest that treatment efforts to reduce pain and improve functioning in OA patients who are overweight or obese should consider addressing both pain catastrophizing and self-efficacy.

Self-efficacy for managing pain, symptoms, and function in patients with lung cancer and their informal caregivers: Associations with symptoms and distress
This study examined self-efficacy for managing pain, symptoms, and function in patients with lung cancer and their caregivers, and associations between self-efficacy and patient and caregiver adjustment. 152 patients with early stage lung cancer completed measures of self-efficacy, pain, fatigue, quality of life, depression, and anxiety. Their caregivers completed a measure assessing their self-efficacy for helping the patient manage symptoms and measures of psychological distress and caregiver strain. Analyses indicated that, overall, patients and caregivers were relatively low in self-efficacy for managing pain, symptoms, and function, and that there were significant associations between self-efficacy and adjustment. Patients low in self-efficacy reported significantly higher levels of pain, fatigue, lung cancer symptoms, depression, and anxiety, and significantly worse physical and functional well being, as did patients whose caregivers were low in self-efficacy. When patients and caregivers both had low self-efficacy, patients reported higher levels of anxiety and poorer quality of life than when both were high in self-efficacy. There were also significant associations between patient and caregiver self-efficacy and caregiver adjustment, with lower levels of self-efficacy associated with higher levels of caregiver strain and psychological distress. These preliminary findings raise the possibility that patient and caregiver self-efficacy for managing pain, symptoms, and function may be important factors affecting adjustment, and that interventions targeted at increasing self-efficacy may be useful in this population
Pain Coping Skills Training for African Americans With Osteoarthritis Study: Baseline Participant Characteristics and Comparison to Prior Studies
Background: The Pain Coping Skills Training for African Americans with OsteoaRTthritis (STAART) trial is examining the effectiveness of a culturally enhanced pain coping skills training (CST) program for African Americans with osteoarthritis (OA). This disparities-focused trial aimed to reach a population with greater symptom severity and risk factors for poor pain-related outcomes than previous studies. This paper compares characteristics of STAART participants with prior studies of CST or cognitive behavioral therapy (CBT)-informed training in pain coping strategies for OA.
Methods: A literature search identified 10 prior trials of pain CST or CBT-informed pain coping training among individuals with OA. We descriptively compared characteristics of STAART participants with other studies, in 3 domains of the National Institutes of Minority Health and Health Disparities' Research Framework: Sociocultural Environment (e.g., age, education, marital status), Biological Vulnerability and Mechanisms (e.g, pain and function, body mass index), and Health Behaviors and Coping (e.g., pain catastrophizing). Means and standard deviations (SDs) or proportions were calculated for STAART participants and extracted from published manuscripts for comparator studies.
Results: The mean age of STAART participants, 59 years (SD = 10.3), was lower than 9 of 10 comparator studies; the proportion of individuals with some education beyond high school, 75%, was comparable to comparator studies (61-86%); and the proportion of individuals who are married or living with a partner, 42%, was lower than comparator studies (62-66%). Comparator studies had less than about 1/3 African American participants. Mean scores on the Western Ontario and McMaster Universities Osteoarthritis Index pain and function scales were higher (worse) for STAART participants than for other studies, and mean body mass index of STAART participants, 35.2 kg/m2 (SD = 8.2), was higher than all other studies (30-34 kg/m2). STAART participants' mean score on the Pain Catastrophizing scale, 19.8 (SD = 12.3), was higher (worse) than other studies reporting this measure (7-17).
Conclusions: Compared with prior studies with predominantly white samples, STAART participants have worse pain and function and more risk factors for negative pain-related outcomes across several domains. Given STAART participants' high mean pain catastrophizing scores, this sample may particularly benefit from the CST intervention approach
