Pain catastrophizing as a treatment process variable in cognitive behavioural therapy for adults with chronic pain.

BACKGROUND: Interdisciplinary cognitive behavioural therapy (CBT) for chronic pain is effective at improving function, mood and pain interference among individuals with disabling chronic pain. Traditionally, CBT assumes that cognitive change is an active therapeutic ingredient in the determination of treatment outcome. Pain catastrophizing, a cognitive response style that views the experience of pain as uncontrollable, permanent and destructive, has been identified as an important maladaptive cognition which contributes to difficulties with the management of chronic pain. Consequently, pain catastrophizing is commonly targeted in CBT for chronic pain. OBJECTIVES: To examine change trajectories in pain catastrophizing during treatment and assess the relevance of these trajectories to outcomes at posttreatment. METHODS: Participants included individuals with chronic pain (N = 463) who completed a 3-week program of interdisciplinary CBT. Pain catastrophizing was assessed weekly over the 3 weeks of treatment and latent growth curve modelling was used to identify trajectories of change. RESULTS: Findings indicated the presence of two classes of linear change, one with a significant negative slope in pain catastrophizing (i.e. improved class) and the other with a non-significant slope (i.e. unchanged class). Next, latent growth mixture modelling examined treatment outcome in relation to class membership. These results indicated that individuals in the 'improved' PCS class had significantly greater improvement in pain interference and mood, as well as physical and mental quality of life compared to the 'unchanged' class. CONCLUSIONS: Implications for our findings, in relation to the CBT model, are discussed.

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.

Difficult Conversations: Training Medical Students to Assess, Educate, and Treat the Patient with Chronic Pain.

OBJECTIVE: Chronic pain, along with opioid abuse and misuse, continues to be a prevalent problem across the USA. Medical students have minimal training in biopsychosocial treatment of chronic pain and often lack the knowledge and skill necessary to address chronic pain with their patients. While there are a variety of treatment options available, research repeatedly has demonstrated that biopsychosocial treatment is the most effective option for chronic pain. Engaging patients in this type of treatment requires training and education. METHODS: The authors implemented a simulation workshop with standardized patients to educate medical students on the physical, psychological, and social aspects of chronic pain and also train students on the most effective ways to discuss chronic pain and educate their patients. Outcomes were measured by a pre- and post-test survey of knowledge, attitudes, and confidence in treating chronic pain, as well as satisfaction with the learning experience. RESULTS: Test and survey results indicated improvements in knowledge, attitudes, and confidence in treating chronic pain. Additionally, students were satisfied with the experience as evidenced by high post-workshop ratings. CONCLUSIONS: Chronic pain training during medical school is associated with students feeling more prepared to provide non-opioid biopsychosocial pain treatment. Additionally, training with standardized patients allows students to learn how to effectively educate their patients, reduce negative confrontations, and maintain a positive physician-patient relationship.

Effect of In-Class vs Online Education on Sexual Health Communication Skills in First-Year Medical Students: a Pilot Study.

OBJECTIVE: Online education is effective for knowledge acquisition, but its effect on clinical skill development is not well characterized. We aimed to compare communication skills of 50 first-year medical students who learned to assess and treat patients through an online learning module vs an in-class lecture. METHODS: Twenty-six students were randomized to learn about antidepressant-induced sexual dysfunction in class and 24 learned the same content through an online module. Students were individually observed conducting an interview with a standardized patient with antidepressant-induced sexual dysfunction. Students were assessed by faculty raters blinded to the student's learning mode. Standardized patients were asked about their willingness to have the student as their physician. RESULTS: More students who learned in class vs online demonstrated appropriate verbal empathy (18 [69%] vs 8 [33%]; P = 0.01), defined as completing each task in the "verbal empathy" assessment domain, as measured by a faculty rater. Other assessed variables were not significantly different. Standardized patients' willingness (vs unwillingness; P = 0.01) to have the student as their physician was associated with the demonstration (by faculty appraisal) of a number of basic skills: using open-ended questions, asking one question at a time, using gender-neutral terminology when asking about the patient's relationship, and using appropriate sexual-health terminology. CONCLUSIONS: This study, although limited by a single-site design and the small number of participants, offers preliminary evidence that, if confirmed, may suggest that in-class learning from a psychiatrist (vs from an online module) is associated with greater verbal empathy in the assessment of SSRI-related sexual dysfunction.

Longitudinal Treatment Outcomes for an Interdisciplinary Pain Rehabilitation Program: Comparisons of Subjective and Objective Outcomes on the Basis of Opioid Use Status.

Chronic pain is a major public health concern, and widespread use of prescription opioids for chronic pain has contributed to the escalating problem of opioid use disorder. Interdisciplinary pain rehabilitation programs (IPRPs) can be highly effective in discontinuing opioids in patients with chronic pain while also improving functional status. This study sought to examine self-report and performance-based functional outcomes of 2 cohorts of patients enrolled in a 3-week IPRP: patients engaged in interdisciplinary pain treatment and physician-supervised opioid taper versus nonopioid users engaged in interdisciplinary treatment. Immediate and long-term treatment outcomes were assessed using a series of 2 (group: opioid use, no opioid use) × 2 (period: pretreatment, post-treatment) and 2 (group: opioid use, no opioid use) × 2 (period: pretreatment, 6 months post-treatment) mixed model analyses of variance. Group × Period interactions were nonsignificant whereas period effects were significant for all outcomes in directions indicating improvement (Ps < .001) at discharge from the program and at 6 months, irrespective of opioid use status. Results support the assertion that IPRPs lead to significant improvements in subjective as well as objective indices of function, irrespective of opioid use status. Implications for our findings are discussed. PERSPECTIVE: This article provides support for the effectiveness of interdisciplinary, rehabilitative models of care in improving physical and emotional functioning of patients with chronic pain while simultaneously discontinuing opioid use. The reach of this work is substantial, because opioid dependency and chronic pain are public health problems in the United States.

Unique Contributions of Acceptance and Catastrophizing on Chronic Pain Adaptation.

PURPOSE: Pain catastrophizing and acceptance represent distinct but interrelated constructs that influence adaptation to chronic pain. Clinical and laboratory research suggest that higher levels of catastrophizing and lower levels of acceptance predict worse functioning; however, findings have been mixed regarding which specific outcomes are associated with each construct. The current study evaluates these constructs in relation to pain, affect, and functioning in a treatment-seeking clinical sample. METHOD: Participants included 249 adult patients who were admitted to an interdisciplinary chronic pain rehabilitation program and completed measures of pain and related psychological and physical functioning. RESULTS: Hierarchical multiple regression analyses indicated that pain catastrophizing and acceptance both significantly, but differentially, predicted depressive symptoms and pain-related negative affect. Only pain catastrophizing was a unique predictor of perceived pain severity, whereas acceptance uniquely predicted pain interference and performance in everyday living activities. There were no significant interactions between acceptance and catastrophizing, suggesting no moderation effects. CONCLUSION: Findings from the current study indicate a pattern of results similar to prior studies in which greater levels of catastrophic thinking is associated with higher perceived pain intensity whereas greater levels of acceptance relate to better functioning in activities despite chronic pain. However, in the current study, both acceptance and catastrophizing were associated with negative affect. These relationships were significant beyond the effects of clinical and demographic variables. These results support the role of pain acceptance as an important contribution to chronic pain-related outcomes alongside the well-established role of pain catastrophizing. Results are limited by reliance on self-report data, cross-sectional design, and low racial/ethnic diversity.

The Mediating Effects of the Different Dimensions of Pain Catastrophizing on Outcomes in an Interdisciplinary Pain Rehabilitation Program.

OBJECTIVE: Although reducing pain catastrophizing has been shown to contribute to functional improvement in patients receiving interdisciplinary pain care, little is known about how changes in the different dimensions of pain catastrophizing uniquely contribute to improvement in outcome. The study examined the unique relationship between changes in the 3 distinct factors of pain catastrophizing-helplessness, rumination, and magnification-and changes in pain outcomes. MATERIALS AND METHODS: In this nonrandomized study, 641 patients who completed treatment in a 3-week interdisciplinary pain rehabilitation program between the years 2013 and 2014 completed a battery of psychometrically validated measures of pain catastrophizing, pain severity, pain interference, mental and physical health-related quality of life, and depressive symptoms at pretreatment and posttreatment. RESULTS: A series of within groups (repeated measures) mediation analyses were conducted. Change in the helplessness, rumination, and magnification subscales were entered as multiple mediators in the model. Analyses revealed that change in helplessness partially mediated improvement in all outcome variables beyond the influence of change in other variables in the model, whereas change in rumination partially mediated improvement in pain severity, interference, and depressive symptoms. Change in magnification had the least impact on outcome, partially mediating improvements in only mental health quality of life. DISCUSSION: Results suggest that changes in the 3 dimensions of pain catastrophizing differentially mediate improvement in pain outcome. Treatment approaches that specifically target helplessness and rumination may be particularly useful in improving the outcomes of patients with refractory pain conditions enrolled in interdisciplinary pain rehabilitation program.

The Relationship Between Pain Catastrophizing and Outcomes of a 3-Week Comprehensive Pain Rehabilitation Program.

OBJECTIVE : Pain catastrophizing is an important predictor of functioning and disability among individuals with chronic pain, and modification of catastrophic interpretations of pain is a proposed treatment mechanism of pain rehabilitation. The purpose of the current study is to examine the relationship between changes in catastrophic thinking and treatment outcomes for a large sample of patients with chronic pain. METHODS : 648 adult patients with chronic pain completed a 3-week intensive outpatient comprehensive pain rehabilitation program. Measures of pain severity, pain-related life interference, depression, and pain catastrophizing were completed at admission and discharge. RESULTS : Consistent with prior research, pain catastrophizing was associated with several negative pain-related outcomes. Results of a within-subjects mediational analysis indicated that pain catastrophizing not only improved during the treatment program, but also accounted for a significant portion of the variance in the reduction of pain severity, pain interference, and depression at the end of treatment. CONCLUSIONS : This study adds further support to the position that pain catastrophizing has a detrimental role in adaptation to chronic pain, and that this construct can be successfully modified in treatment to improve patient outcomes.

Patients' perceptions of a chronic pain rehabilitation program: changing the conversation.

Objective Research supports the effectiveness of comprehensive approaches to chronic pain treatment, including behavioral management and physical reconditioning. However, less is known about patients' perceptions of this treatment approach. The current study evaluated patient perceptions and treatment outcomes utilizing both qualitative and quantitative data collection. Methods A total of 498 adult patients (≥18 years of age; Mage = 49.1) completed an intensive outpatient interdisciplinary chronic pain rehabilitation program, completed survey measures at admission and discharge, and were asked open-ended questions about their treatment experience at discharge. Results Patients reported significant decreases in pain severity, t(488) = 23.08, p < .001, and pain-related interference, t(488) = 24.28, p < .001, at discharge. Patients endorsed self-management strategies, particularly relaxation skills (85%), moderation and/or modification (47%), and exercise, stretching and/or physical therapy (39%) as the most important aspects of treatment. Conclusions Patients perceive behavioral skills to manage pain and physical reconditioning to be important components of a successful pain rehabilitation program. These findings can inform conversations with both physicians and patients about the importance of biopsychosocial approaches to pain management. Key limitations include a lack of racial/ethnic diversity, use of anonymous data that cannot be linked directly to patient outcomes, and reliance on self-report data.

Rumination, Magnification, and Helplessness: How do Different Aspects of Pain Catastrophizing Relate to Pain Severity and Functioning?

OBJECTIVES: Although there is a large body of research on the relationship between pain catastrophizing and functioning among individuals with chronic pain, little is known about the potential differential impact of specific aspects of pain catastrophizing. The current study evaluates the relationship between the Rumination, Helplessness, and Magnification subscales of the Pain Catastrophizing Scale and pain-related outcomes. MATERIALS AND METHODS: In total, 844 patients who were admitted to a chronic pain rehabilitation program completed survey measures of pain, catastrophizing, quality of life (QOL), and depression. RESULTS: A series of analyses were conducted entering the 3 subscales simultaneously in a predictive model after pain intensity and demographic variables (ie, age, sex, pain duration, current opioid use). The Helplessness subscale accounted for unique variance in the prediction of pain severity, pain-related interference, mental and physical health-related QOL, and depressed mood. Magnification was significantly related to physical and mental health-related QOL and depressed mood. The Rumination subscale was not uniquely associated with any of the outcome measures beyond that which was accounted for by pain severity, magnification, or helplessness. DISCUSSION: Pain catastrophizing is a multifaceted construct, and different domains of catastrophizing are uniquely related to pain-related outcomes. This study represents the first to evaluate the functioning of these subscales in a large, diagnostically heterogeneous sample of chronic pain patients.

Control strategies and suicidal ideation in older primary care patients with functional limitations.

OBJECTIVES: Failure to adapt to limitations in control may place older adults at risk for suicidal behavior. The present study examined the relation between control strategies, depressive symptoms, and suicidal ideation in older adults with health-related limitations. METHODS: Cross-sectional study of 50 older adult (aged 65-94) primary care patients with health-related limitations. RESULTS: Compensatory primary control strategies characterized by seeking help from others were associated with lower levels of suicidal ideation, independent of depressive symptoms. Selective primary control strategies (e.g., persistence) were also associated with reduced suicidal ideation independent of depressive symptoms, but only when a low level of compensatory primary control strategies was endorsed. Selective secondary control strategies were associated with higher suicidal ideation, whereas compensatory secondary control strategies (e.g., goal disengagement) were unrelated in this sample after controlling for covariates. CONCLUSIONS: Findings demonstrate that primary care patients with functional limitations who are not striving to meet their goals, either through persistence or by seeking help from others, are at elevated risk of suicidal thinking.

Insomnia symptoms, nightmares, and suicidal ideation in older adults.

OBJECTIVES: Prior research has found that insomnia symptoms and nightmares are associated with suicidal ideation, suicide attempts, and death by suicide. However, to the best of our knowledge, no research has examined the relation between insomnia symptoms, nightmares, and suicidal ideation in older adults. The current project aimed to fill this void by investigating the relation between insomnia symptoms, nightmares, and suicidal ideation in an older adult sample. METHOD: The study utilized a cross-sectional design. The sample consisted of 81 older adult patients (age ≥ 65 years) recruited from a family medicine clinic. The participants were asked to complete surveys about their sleep, symptoms of depression, and suicidal ideation. RESULTS: Insomnia symptoms, but not nightmares, were significantly related to suicidal ideation. In addition, insomnia symptoms were related to suicidal ideation independent of nightmares. Furthermore, the relation between insomnia symptoms and suicidal ideation was mediated by depressive symptoms. DISCUSSION: These findings have implications for the identification and treatment of suicidal ideation in older adults.

Impact of opioid use on outcomes of functional restoration.

OBJECTIVES: To examine the effect of opioid use on psychological function, physical functioning, and return-to-work outcomes of a multidisciplinary rehabilitation program (MRP) for chronic pain. METHODS: The participants were 127 patients with on-the-job injuries who had completed an MRP between 2001 and 2003. Opioid use was controlled by the patients' treating physicians (who were not affiliated with the MRP) and was assessed via patient self-report at the time of admission to the program and discharge. Other measures included pretreatment and posttreatment assessments of depression, pain severity, perceived disability, and physical ability (floor-to-waist lifting capacity). Return-to-work outcomes were obtained via follow-up phone calls approximately 6 months posttreatment. RESULTS: Significant improvements from pretreatment to posttreatment were evidenced on all psychological and physical measures for both opioid users and nonusers. Further, there were no significant posttreatment differences between opioid and nonopioid users on psychological, physical, or return-to-work outcomes. DISCUSSION: The role of opioids in the treatment of chronic pain continues to be controversial. Despite a lack of definitive data on their effectiveness, opioids continue to be prescribed, and thus patients using opioids continue to present for multidisciplinary rehabilitation. Although further exploration is warranted, results of the current study suggest that opioid use during rehabilitation does not necessarily preclude treatment success.

Pain-related anxiety in the prediction of chronic low-back pain distress.

This study evaluated the relation of particular aspects of pain-related anxiety to characteristics of chronic pain distress in a sample of 76 individuals with low-back pain. Consistent with contemporary cognitive-behavioral models of chronic pain, the cognitive dimension of the Pain Anxiety Symptoms Scale (PASS; McCracken, Zayfert, and Gross, 1992, Pain 50:67-73) was uniquely predictive of cognitive-affective aspects of chronic pain, including affective distress, perceived lack of control, and pain severity. In contrast, the escape and avoidance dimension of the PASS was more predictive of behavioral interference in life activities. Overall, the findings are discussed within the context of identifying particular pain-related anxiety mechanisms contributing to differential aspects of pain-related distress and clinical impairment.
