Mobile health intervention to address chronic pain among those who engage in hazardous drinking: A pilot study.

BACKGROUND: Hazardous drinking has been associated with chronic pain in community and medical samples. The purpose of this study was to develop a novel, integrated mobile health intervention that improves pain management and reduces hazardous drinking that may be implemented in primary care settings. METHODS: Forty-eight participants with moderate or greater chronic pain and hazardous drinking were recruited from primary care clinics and through social media sites. Following baseline assessment, participants were randomized to a counselor-supported smartphone app intervention (INTV) or a counselor delivered treatment-as-usual control condition (CTL). RESULTS: Results supported the feasibility and acceptability of the smartphone app intervention. Participants found it easy to use, reported high levels of satisfaction, and showed high levels of engagement with the app. Between-group effect size estimates at follow-up showed small effects for the intervention on pain ratings. However, using clinically meaningful change thresholds of 30% and 50% improvement in pain scores, 38% and 25% respectively of those in the INTV condition showed reductions compared to 20% and 12.5% respectively in the CTL condition. Effect size estimates did not indicate intervention superiority on alcohol outcomes as participants in both conditions showed considerable reductions in drinking over the course of the study. CONCLUSIONS: Results supported the view that a mobile health intervention delivered via smartphone with electronic coaching is a feasible and acceptable method of addressing chronic pain among those who engage in hazardous drinking. Future work should test the efficacy of this approach in a fully powered trial.

Pilot Study of Low-dose Naltrexone for the Treatment of Chronic Pain Due to Arthritis: A Randomized, Double-blind, Placebo-controlled, Crossover Clinical Trial.

PURPOSE: Low-dose naltrexone (LDN) is commonly used to control pain and other symptoms, especially in patients with autoimmune diseases, but with limited evidence. This study tests the efficacy of LDN in reducing chronic pain in patients with osteoarthritis (OA) and inflammatory arthritis (IA), where existing approaches often fail to adequately control pain. METHODS: In this randomized, double-blind, placebo-controlled, crossover clinical trial, each patient received 4.5 mg LDN for 8 weeks and placebo for 8 weeks. Outcome measures were patient reported, using validated questionnaires. The primary outcome was differences in pain interference during the LDN and placebo periods, using the Brief Pain Inventory (scale, 0-70). Secondary outcomes included changes in mean pain severity, fatigue, depression, and multiple domains of health-related quality of life. The painDETECT questionnaire classified pain as nociceptive, neuropathic, or mixed. Data were analyzed using mixed-effects models. FINDINGS: Seventeen patients with OA and 6 with IA completed the pilot study. Most patients described their pain as nociceptive (n = 9) or mixed (n = 8) rather than neuropathic (n = 3). There was no difference in change in pain interference after treatment with LDN (mean [SD], -23 [19.4]) versus placebo (mean [SD], -22 [19.2]; P = 0.90). No significant differences were seen in pain severity, fatigue, depression, or health-related quality of life. IMPLICATIONS: In this small pilot study, findings do not support LDN being efficacious in reducing nociceptive pain due to arthritis. Too few patients were enrolled to rule out modest benefit or to assess inflammatory or neuropathic pain. CLINICALTRIALS: gov identifier: NCT03008590.

An integrated videoconferencing intervention for chronic pain and heavy drinking among patients in HIV-care: a proof-of-concept study.

Chronic pain and heavy drinking are common comorbid conditions among people living with HIV/AIDS (PLWHA). An integrated approach to address these co-occurring conditions in a manner that facilitates treatment utilization would represent an important advance in HIV-care. This study examined the acceptability and feasibility of a tailored, videoconferencing intervention to reduce chronic pain and heavy drinking among PLWHA. Participants in HIV-care (n = 8) completed baseline assessments and an in-person intervention session followed by 6 videoconferencing sessions. Acceptability and feasibility were assessed with patient satisfaction ratings and interview responses 8 weeks following baseline along with videoconferencing use during the intervention period. Treatment satisfaction and comprehensibility ratings were high and supported by interview responses indicating the value of the intervention content, treatment alliance, and format. All participants successfully enabled videoconferencing on their own smartphones and completed a median number of 4.5 (out of 6) video-sessions. Changes in heavy drinking and pain provided additional support for the potential utility of this approach. Results suggest that this videoconferencing intervention is an acceptable and feasible method of addressing chronic pain and heavy drinking among PLWHA. Findings provide the basis for future work to examine the efficacy of this approach in a Stage 1b trial.

The Interaction Between Chronic Pain and PTSD.

PURPOSE OF REVIEW: Post-traumatic stress disorder (PTSD) and chronic pain often co-occur. Understanding the shared mechanisms, signs to identify PTSD, and treatment options is integral in allowing providers to better serve their patients. RECENT FINDINGS: Individuals with comorbid PTSD and chronic pain report greater PTSD symptoms, pain, anxiety, depression, disability, and opioid use than those with only one of these conditions. There are several empirically supported therapies for chronic pain, and for PTSD, as well as pilot data for a treatment of comorbid pain and PTSD. The purpose of this paper is to review and synthesize current literature investigating the interaction between chronic pain and PTSD, and provide treatment recommendations for providers treating patients with chronic pain and PTSD.

Development of a tailored, telehealth intervention to address chronic pain and heavy drinking among people with HIV infection: integrating perspectives of patients in HIV care.

BACKGROUND: Chronic pain and heavy drinking commonly co-occur and can influence the course of HIV. There have been no interventions designed to address both of these conditions among people living with HIV (PLWH), and none that have used telehealth methods. The purpose of this study was to better understand pain symptoms, patterns of alcohol use, treatment experiences, and technology use among PLWH in order to tailor a telehealth intervention that addresses these conditions. SUBJECTS: Ten participants with moderate or greater chronic pain and heavy drinking were recruited from a cohort of patients engaged in HIV-care (Boston Alcohol Research Collaborative on HIV/AIDS Cohort) and from an integrated HIV/primary care clinic at a large urban hospital. METHODS: One-on-one interviews were conducted with participants to understand experiences and treatment of HIV, chronic pain, and alcohol use. Participants' perceptions of the influence of alcohol on HIV and chronic pain were explored as was motivation to change drinking. Technology use and treatment preferences were examined in the final section of the interview. Interviews were recorded, transcribed and uploaded into NVivo® v12 software for analysis. A codebook was developed based on interviews followed by thematic analysis in which specific meanings were assigned to codes. Interviews were supplemented with Likert-response items to evaluate components of the proposed intervention. RESULTS: A number of themes were identified that had implications for intervention tailoring including: resilience in coping with HIV; autonomy in health care decision-making; coping with pain, stress, and emotion; understanding treatment rationale; depression and social withdrawal; motives to drink and refrain from drinking; technology use and capacity; and preference for intervention structure and style. Ratings of intervention components indicated that participants viewed each of the proposed intervention content areas as "helpful" to "very helpful". Videoconferencing was viewed as an acceptable modality for intervention delivery. CONCLUSIONS: Results helped specify treatment targets and provided information about how to enhance intervention delivery. The interviews supported the view that videoconferencing is an acceptable telehealth method of addressing chronic pain and heavy drinking among PLWH.

Further Examination of the Pain Stages of Change Questionnaires Among Chronic Low Back Pain Patients: Long-term Predictive Validity of Pretreatment and Posttreatment Change Scores and Stability of Posttreatment Scores.

OBJECTIVES: In order to maximize the therapeutic benefits of cognitive-behavioral therapy (CBT) for chronic pain, individuals need to be motivated to adopt a self-management approach. The Pain Stages of Change Questionnaire (PSOCQ) was developed to measure patients' readiness to adopt a self-management approach to chronic pain. The present study examined whether pretreatment and posttreatment PSOCQ change scores among chronic low back pain patients could predict 6- and 12-month follow-up outcomes, and the stability of posttreatment PSOCQ scores during follow-up. METHODS: Participants were recruited from a VA primary care clinic. Data from 60 participants assigned to either regular CBT or a modified CBT (ie, PRIME CBT) condition were analyzed in the present study. Self-report measures including PSOCQ, pain severity, disability, and depressive symptom severity were administered at pretreatment, 10 weeks posttreatment, 6-month and follow-up assessments. RESULTS: Multiple regression analyses showed that pretreatment and posttreatment changes in the Action/Maintenance scores significantly predicted pain severity at 6 months, and changes in the Precontemplation scores significantly predicted disability at 6 months. None of the PSOCQ change scores significantly predicted depressive symptom severity. Posttreatment Precontemplation and Action/Maintenance scores were quite stable, even at 12-month follow-up. CONCLUSIONS: Changes in patients' attitudes toward adopting a pain self-management approach may serve as one of the therapeutic mechanisms and predict long-term function. This study also revealed that changed attitudes toward chronic pain self-management remain quite stable over time. Adoption of beliefs consistent with chronic pain self-management during treatment may promote sustained benefits.

Confirmatory factor analysis of the Coping Strategies Questionnaire-Revised for veterans with pain.

As the need for appropriate assessment and treatment of veterans with chronic pain continues to grow, it is important to ensure that the instruments we use to complete these assessments, such as the Coping Strategies Questionnaire-Revised (CSQ-R), are validated on this population. The purpose of the present study was to confirm the factor structure of the CSQ-R in veterans. Secondary analyses examined associations between various pain coping strategies and measures of mood and health functioning. Participants consisted of 281 veterans who were referred to and evaluated by a Psychology Pain Management Program in a northeastern Department of Veterans Affairs health care facility. Participants completed self-report questionnaires including the CSQ-R and measures of disability, mood, and health. Confirmatory factor analysis (CFA) compared the 6-factor solution to models identified in other studies. The CFA indicated that the 6-factor solution of the CSQ-R proposed by Riley and Robinson (1997) is valid and has the best fit of all models tested when used with veterans. The results of the secondary correlational analyses were consistent with previous research indicating that coping self-statements and ignoring pain are adaptive pain coping strategies. Our findings support the psychometric soundness of the 6-factor CSQ-R when used with veterans with chronic pain. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Potential neurobiological benefits of exercise in chronic pain and posttraumatic stress disorder: Pilot study.

This pilot study assessed the effects of cardiopulmonary exercise testing and cardiorespiratory fitness on plasma neuropeptide Y (NPY), allopregnanolone and pregnanolone (ALLO), cortisol, and dehydroepiandrosterone (DHEA), and their association with pain sensitivity. Medication-free trauma-exposed participants were either healthy (n = 7) or experiencing comorbid chronic pain/posttraumatic stress disorder (PTSD) (n = 5). Peak oxygen consumption (VO2) during exercise testing was used to characterize cardiorespiratory fitness. Peak VO2 correlated with baseline and peak NPY levels (r = 0.66, p < 0.05 and r = 0.69, p < 0.05, respectively), as well as exercise-induced changes in ALLO (r = 0.89, p < 0.001) and peak ALLO levels (r = 0.71, p < 0.01). NPY levels at the peak of exercise correlated with pain threshold 30 min after exercise (r = 0.65, p < 0.05), while exercise-induced increases in ALLO correlated with pain tolerance 30 min after exercise (r = 0.64, p < 0.05). In contrast, exercise-induced changes in cortisol and DHEA levels were inversely correlated with pain tolerance after exercise (r = -0.69, p < 0.05 and r = -0.58, p < 0.05, respectively). These data suggest that cardiorespiratory fitness is associated with higher plasma NPY levels and increased ALLO responses to exercise, which in turn relate to pain sensitivity. Future work will examine whether progressive exercise training increases cardiorespiratory fitness in association with increases in NPY and ALLO and reductions in pain sensitivity in chronic pain patients with PTSD.

The Longitudinal Impact of Parent Distress and Behavior on Functional Outcomes Among Youth With Chronic Pain.

UNLABELLED: Accumulating evidence supports the concurrent association between parent distress and behavior and child functioning in the context of chronic pain, with existing longitudinal studies limited to a pediatric surgical context that identify parent catastrophizing as influential. In this study, we examined how parent factors assessed at a multidisciplinary pediatric pain clinic evaluation affect child psychological and functional outcomes over time. A cohort of 195 patients with chronic pain (ages 8-17 years) and their parents who presented for a multidisciplinary evaluation completed measures at baseline and at 4-month follow-up. Patients completed measures of pain catastrophizing, pain-related fear and avoidance, generalized anxiety, depressive symptoms, and functional disability. Parents completed measures of pain catastrophizing, pain-related fear and avoidance, and protective responses to child pain. Parent-reported child school functioning was also collected. Parent distress and behavior was concurrently associated with child distress and functioning at evaluation. After controlling for baseline child functioning, baseline parent avoidance and protective behavior emerged as significant predictors of child functioning at 4-month follow-up. Parent distress and behavior influence child distress and functioning over time and these findings identify key parent domains to target in the context of a child's pain treatment. PERSPECTIVE: Parent behavior, specifically avoidance and protective responses, influence child distress and functioning over time. Child pain treatment interventions should include influential parent factors to ensure successful outcomes.

Sleep Quality and Reexperiencing Symptoms of PTSD Are Associated With Current Pain in U.S. OEF/OIF/OND Veterans With and Without mTBIs.

Pain, a debilitating condition, is frequently reported by U.S. veterans returning from Afghanistan and Iraq. This study investigated how commonly reported clinical factors were associated with pain and whether these associations differed for individuals with a history of chronic pain. From the Boston metropolitan area, 171 veterans enrolled in the Veterans Affairs Center of Excellence were assessed for current posttraumatic stress disorder (PTSD) symptom severity, current mood and anxiety diagnoses, lifetime traumatic brain injury, combat experiences, sleep quality, and alcohol use. Hierarchical regression models were used to determine the association of these conditions with current pain. Average pain for the previous 30 days, assessed with the McGill Pain Questionnaire, was 30.07 out of 100 (SD = 25.43). Sleep quality, PTSD symptom severity, and alcohol use were significantly associated with pain (R(2) = .24), as were reexperiencing symptoms of PTSD (R(2) = .25). For participants with a history of chronic pain (n = 65), only PTSD symptoms were associated with pain (R(2) = .19). Current pain severity was associated with increased PTSD severity (notably, reexperiencing symptoms), poor sleep quality, and increased alcohol use. These data support the hypothesis that PTSD symptoms influence pain, but suggest that problems with sleep and alcohol use may exacerbate the relationship.

The shared neuroanatomy and neurobiology of comorbid chronic pain and PTSD: therapeutic implications.

Chronic pain and posttraumatic stress disorder (PTSD) are disabling conditions that affect biological, psychological, and social domains of functioning. Clinical research demonstrates that patients who are affected by chronic pain and PTSD in combination experience greater pain, affective distress, and disability than patients with either condition alone. Additional research is needed to delineate the interrelated pathophysiology of chronic pain and PTSD, with the goal of facilitating more effective therapies to treat both conditions more effectively; current treatment strategies for chronic pain associated with PTSD have limited efficacy and place a heavy burden on patients, who must visit various specialists to manage these conditions separately. This article focuses on neurobiological factors that may contribute to the coprevalence and synergistic interactions of chronic pain and PTSD. First, we outline how circuits that mediate emotional distress and physiological threat, including pain, converge. Secondly, we discuss specific neurobiological mediators and modulators of these circuits that may contribute to chronic pain and PTSD symptoms. For example, neuropeptide Y, and the neuroactive steroids allopregnanolone and pregnanolone (together termed ALLO) have antistress and antinociceptive properties. Reduced levels of neuropeptide Y and ALLO have been implicated in the pathophysiology of both chronic pain and PTSD. The potential contribution of opioid and cannabinoid system factors also will be discussed. Finally, we address potential novel methods to restore the normal function of these systems. Such novel perspectives regarding disease and disease management are vital to the pursuit of relief for the many individuals who struggle with these disabling conditions.

An examination of the impact of clinically significant levels of posttraumatic stress disorder symptomatology on the classification of pain as mild, moderate, or severe in a sample of veterans with chronic pain.

Chronic pain affects approximately 50% of veterans, half of whom also suffer from posttraumatic stress disorder (PTSD). Researchers have previously identified a method for translating 0-10 pain scales to categories of pain (mild, moderate, or severe pain) to make pain ratings more meaningful in the context of category-based treatment guidelines. Although one such study focused on veterans with pain, none have considered whether empirically derived cutoffs differ based on the presence of clinically significant levels of PTSD symptomatology. Therefore, the purpose of the study presented here was to replicate previous findings on pain categorization in veterans and to assess whether the cutoffs differ based on the presence or absence of clinically significant levels of PTSD symptomatology. On the basis of the responses of 198 veterans, our results supported the previous finding that scores of 1-4 are classified as mild pain, 5-7 as moderate, and 8-10 as severe. In addition, veterans with comorbid pain and clinically significant levels of PTSD symptomatology were found to have a lower cutoff between mild and moderate pain, but they did not have a different cutoff between moderate and severe pain. These results, which support that lower levels of pain severity are associated with higher levels of pain-related interference for veterans with comorbid pain and clinically significant levels of PTSD symptomatology relative to veterans with pain without clinically significant levels of PTSD symptomatology, highlight the importance of considering contextual factors (e.g., psychosocial factors) when assessing a veteran's pain severity.

A randomized controlled pilot study of a cognitive-behavioral therapy approach for painful diabetic peripheral neuropathy.

UNLABELLED: The purpose of the present pilot study was to assess the efficacy of cognitive-behavioral therapy (CBT) for painful diabetic peripheral neuropathy. This was a randomized, treatment as usual (TAU), controlled, nonblinded intervention pilot study with a 4-month follow-up conducted in a VA medical center. It was hypothesized that participants who received CBT, as compared to those who received TAU, would report significant decreases on self-report measures of pain severity, interference, and depressive symptoms from pretreatment to 4-month follow-up. Participants meeting inclusion criteria were randomly assigned to 1 of the study conditions. Of the 20 eligible participants, 12 were randomized to CBT and 8 were randomized to TAU. Participants randomized to CBT showed significant decreases on measures of pain severity (B = -.54) and pain interference (B = -.77) from pretreatment to 4-month follow-up. There were no significant changes in the TAU participants' scores on measures of pain severity (B = .00) or pain interference (B = -.09). Neither CBT nor TAU participants showed significant changes in their levels of depressive symptoms from pretreatment to 4-month follow-up. CBT may be an effective treatment approach for reducing pain severity and interference associated with painful diabetic peripheral neuropathy. PERSPECTIVE: The results of this study suggest that engaging patients in CBT for painful diabetic peripheral neuropathy may provide them the skills to become more active and experience less pain.

Complicating factors associated with mild traumatic brain injury: impact on pain and posttraumatic stress disorder treatment.

The nature of combat in Iraq and Afghanistan has resulted in high rates of comorbidity among chronic pain, posttraumatic stress disorder (PTSD), and mild traumatic brain injury (mTBI) in Veterans of Operations Enduring Freedom and Iraqi Freedom (OEF/OIF). Although separate evidence-based psychological treatments have been developed for chronic pain and PTSD, far less is known about how to approach treatment when these conditions co-occur, and especially when they co-occur with mTBI. To provide the best care possible for OEF/OIF Veterans, clinicians need to have a clearer understanding of how to identify these conditions, ways in which these conditions may interact with one another, and ways in which existing evidence-based treatments can be modified to meet the needs of individuals with mTBI. The purpose of the present paper is to review the comorbidity of pain, PTSD, and mTBI in OEF/OIF Veterans, and provide recommendations to clinicians who provide care to Veterans with these conditions. First, we will begin with an overview of the presentation, symptomatology, and treatment of chronic pain and PTSD. The challenges associated with mTBI in OEF/OIF Veterans will be reported and data will be presented on the comorbidity among all three of these conditions in OEF/OIF Veterans. Second, we will present recommendations for providing psychological treatment for chronic pain and PTSD when comorbid with mTBI. Finally, the paper concludes with a discussion of the need for a multidisciplinary treatment approach, as well as a call for continued research to further refine existing treatments for these conditions.

The development of an integrated treatment for veterans with comorbid chronic pain and posttraumatic stress disorder.

OBJECTIVE: The purpose of this article is to describe the development of the first integrated treatment for Veterans with comorbid chronic pain and posttraumatic stress disorder (PTSD). DESIGN: Descriptive, including pre- and posttreatment assessment results from a pilot study of six veterans with comorbid chronic pain and PTSD. SETTING: Northeastern Department of Veterans Affairs Medical Center. INTERVENTIONS: Using components of cognitive processing therapy (CPT) for PTSD and cognitive behavioral therapy (CBT) for chronic pain management, a 12-session integrated treatment for veterans with comorbid chronic pain and PTSD was developed. A therapist manual and patient workbook that included weekly readings and homework assignments were created. Participants received pre- and posttreatment evaluations using measures of pain, PTSD, physical disability, and psychological distress. The treatment development process is reviewed and the benefits and challenges of implementing this integrated treatment are presented. RESULTS: Several themes emerged over the course of implementing the treatment, including the importance of establishing participant trust, regular therapy attendance, and addressing participant avoidance. Of the six participants recruited for the pilot study, three withdrew from the study and three completed the integrated treatment. Participants reported that they generally liked the format of treatment, appreciated learning about the ways that chronic pain and PTSD share some common symptoms, and ways that the two disorders can interact with one another. The assessment results of those who completed treatment suggest that this treatment approach is feasible and may have clinical benefit. CONCLUSIONS: Participants appeared to benefit from receiving the integrated treatment for pain and PTSD. A randomized clinical trial is currently being conducted to evaluate the efficacy of this treatment approach.

Prevalence of chronic pain, posttraumatic stress disorder, and persistent postconcussive symptoms in OIF/OEF veterans: polytrauma clinical triad.

This study examines the prevalence and coprevalence with which returning Operation Iraqi Freedom (OIF)/Operation Enduring Freedom (OEF) veterans were reporting symptoms consistent with chronic pain, posttraumatic stress disorder (PTSD), and persistent postconcussive symptoms (PPCS). The medical records of 340 OIF/OEF veterans seen at a Department of Veterans Affairs Polytrauma Network Site were comprehensively reviewed. Analyses indicated a high prevalence of all three conditions in this population, with chronic pain, PTSD, and PPCS present in 81.5%, 68.2%, and 66.8%, respectively. Only 12 of the veterans (3.5%) had no chronic pain, PTSD, or PPCS. The frequency at which these three conditions were present in isolation (10.3%, 2.9%, and 5.3%, respectively) was significantly lower than the frequency at which they were present in combination with one another, with 42.1% of the sample being diagnosed with all three conditions simultaneously. The most common chronic pain locations were the back (58%) and head (55%). These results underscore the complexity of the presenting complaints in OIF/OEF veterans and support the importance of a multidisciplinary team approach to assessment and treatment.

Integration and coordination of pain management in primary care.

Pain is one of the most common symptoms reported to primary care providers and has significant implications for health care costs. The primary aim of this article is to describe and illustrate how to integrate the treatment of chronic pain in the primary care setting. First, we address the integration and coordination of care between mental health and primary care. We then present a typical case and discuss the patient's treatment, outcome, and prognosis. The article concludes with a discussion of issues that frequently arise when integrating psychological treatment for pain in primary care settings.

Support and coronary heart disease: the importance of significant other responses.

In addition to the recognized benefits of social support, there is evidence across several health-related disorders suggesting that specific types of support can contribute to negative outcomes. Informed by theory and research examining the role of pain-related interpersonal interactions in the perpetuation of chronic pain, this study examined whether specific responses from significant others to expressions of coronary heart disease(CHD) related symptoms and incapacity are associated with level of symptoms, degree of disability, and depressive symptom severity among persons with symptomatic CHD. Forty-nine persons with CHD completed self-report questionnaires of the constructs of interest. Regression analyses revealed that degree of perceived solicitious responding to CHD symptoms was associated with increased symptom severity, disability, and depressive symptoms. Results are consistent with an operant-conditioning model and suggest that positive attention from significant others contingent on expressions of CHD symptoms may unwittingly serve to reinforce symptom occurrence and expression, concomitant disability, and emotional distress.

An examination of the relationship between chronic pain and post-traumatic stress disorder.

Chronic pain and post-traumatic stress disorder (PTSD) are frequently observed within the Department of Veterans Affairs healthcare system and are often associated with a significant level of affective distress and physical disability. Clinical practice and research suggest that these two conditions co-occur at a high rate and may interact in such a way as to negatively impact the course of either disorder; however, relatively little research has been conducted in this area. This review summarizes the current literature pertaining to the prevalence and development of chronic pain and PTSD. Research describing the comorbidity of both conditions is reviewed, and several theoretical models are presented to explain the mechanisms by which these two disorders may be maintained. Future directions for research and clinical implications are discussed.
