Chronic musculoskeletal pain has a highly negative impact on Veterans, especially those with serious mental illness (SMI). Chronic musculoskeletal pain leads to poorer mental and physical health-related functioning, representing a critical obstacle to rehabilitation and recovery for SMI Veterans. Despite known high prevalence rates of chronic pain in SMI populations, there is little research to evaluate nonpharmacological pain management strategies in this population. This study aims to address this research and clinical gap by testing the efficacy of Cognitive Behavioral Therapy for Chronic Pain (CBT-CP) - a VA evidence-based psychotherapy for chronic pain - in Veterans with SMI and chronic low back pain. The study will primarily evaluate the impact of CBT-CP on pain-related functioning, quality of life, and pain severity. This study will also examine relationships between pain and mental health symptoms, and how these relationships may change with CBT-CP completion.
Project Background: Chronic musculoskeletal pain is one of the most common physical health diagnoses among individuals with SMI. Individuals with SMI and chronic musculoskeletal pain report worse mental and physical health functioning relative to people with other mental or physical health conditions. Despite knowing about high rates of chronic musculoskeletal pain among individuals with SMI; little research has been conducted to further understand the complex relation between pain and psychiatric symptoms and consider the usefulness or appropriateness of current treatment approaches. What is known is problematic: Veterans with SMI are largely not provided options for nonpharmacological pain management strategies, including CBT-CP, and are more likely to be prescribed pain medications that pose unique risks to this population.
Project Objectives: The proposed Merit research will address research and clinical gaps by testing the efficacy of CBT-CP in Veterans with SMI and chronic musculoskeletal pain, notably chronic low back pain. The investigators will complete a large, randomized controlled trial with 190 Veterans, comparing CBT-CP to an active control condition ("Health \& Wellness"). The investigators will examine effects of treatment on functioning and pain interference, quality of life, and pain severity. The investigators will evaluate these variables at baseline, post-treatment, and six months post-treatment through both standardized assessment procedures and timepoints; as well as a one-week ecological momentary assessment (EMA) period prior to each assessment timepoint. The EMA data will allow us to examine inter- and intra-variability in pain and related functioning, including its relationship to SMI symptoms, and to evaluate how engagement in CBT-CP may affect pain variability and its relationship to mental health.
Project Methods: This project will include completing a randomized control trial (RCT) with 190 Veteran participants, evaluating impact of CBT-CP versus Health \& Wellness on pain-related functioning and interference, quality of life, and pain severity. The investigators will also explore process variables, including physical activity and pain catastrophizing, as well as moderators, including SMI diagnosis and symptom severity along with pain severity at baseline, to see how these variables affect treatment engagement and outcomes.

Exclusion Criteria:
Cognitive Behavioral Therapy for Chronic Pain (CBT-CP) will be conducted in accordance with the Cognitive Behavioral Therapy for Chronic Pain: Therapist Manual and the VA Evidence-Based Practice (EBP) roll-out training. CBT-CP consists of a 12-session protocol, including an initial assessment session (BL assessment; Session 1), 10 content-specific sessions (pain education, goal-setting, cognitive and behavioral skill building; Sessions 2-11), and a booster session scheduled approximately one month after the final CBT-CP session (Session 12). Participants randomized to the CBT-CP condition (n = 30) will complete one 60-minute individual session per week. Each CBT-CP session will be led by a trained study interventionist using a manualized curriculum, following a basic structure including review of previous session material, introduction of new information or skills, and discussion of how to implement learned material into a home action plan.
Behavioral: Cognitive Behavioral Therapy for Chronic Pain (CBT-CP)
Health \& Wellness (H\&W) was developed by VISN 5 MIRECC investigators and consists of psychoeducation on topics related to physical and emotional wellbeing. Its structure is similar to CBT-CP (10 weekly individual 60-minute sessions, no booster session). Each Health \& Wellness session will be led by a trained interventionist using a manualized curriculum that includes review of previous session material, introduction of new information, and discussion of a range of health-related topics (physical activity/exercise, nutrition/healthy eating, managing medications and side effects, and addictive behaviors (e.g., substance use, gambling, eating) that do not include pain. Typical sessions include discussion of the impact of the topic on overall health and well-being, identifying benefits and challenges to improving or maintaining health in that area, and strategies to address challenges in that area.

Brief Pain Inventory-Interference (BPI-INT)
The Brief pain Inventory - Interference subscale (BPI-INT) is a 9-item questionnaire measuring pain-relate interference. Respondents answer the degree to which pain interferes with mood/affect and physical activity on a scale from 0 (not at all) to 10 (all the time/completely). An average score is calculated, with a score of \>= 4 indicating moderate to severe pain interference. The instrument has excellent psychometric properties and is regularly used in pain research and clinical practice.
Time frame: post-treatment (~4 months after randomization); 6-month follow-up (~10 months after randomization)
Veterans RAND 36-Item Health Survey (VR-36)
The Veterans RAND 36-Item Health Survey (VR-36) is a 36-item questionnaire measuring health-related quality of life and 8 domains of health-related functioning (physical functioning, role limitations due to physical problems, role limitations due to emotional problems, bodily pain, general health perceptions, vitality, social functioning, and mental health). Items are scored on a 3- to 6-point scale and are summed to create a total and domain scores, ranging from 0 (worst health status) to 100 (best health status). The VR-36 demonstrated improved reliability, precision, and validity compared to the SF-36 and among persons with SMI.
Time frame: post-treatment (~4 months after randomization); 6-month follow-up (~10 months after randomization)
PEG-3
The PEG-3 will assess pain severity and related functioning and quality of life (enjoyment, general activity), using a 0 to 10 rating scale with qualifying statements for each numeric rating; a rating of 4 or greater indicates moderate-to-severe pain intensity. The PEG-3 will be included in the Ecological Momentary Assessment (EMA) surveys; Veterans will be asked about the extent to which they have experienced each item in the one hour prior to survey completion. The PEG-3 has been validated in Veterans receiving VA primary care services and has good reliability and validity when compared to longer pain assessments. As a primary outcome, changes in the two items assessing functioning (General activity interference) and quality of life (Enjoyment of life) will be examined.
Time frame: post-treatment (~4 months after randomization); 6-month follow-up (~10 months after randomization)
Pain Numeric Rating Scale (PNRS)
Pain severity will be rated using the Pain Numeric Rating Scale (PNRS). It is a 3-item scale assessing the person's average, worst, and least pain during the past week. Each item is rated on a scale from 0 (no pain) to 10 (worst pain). The items are averaged together to create a more accurate "average" pain score, with a score of \>= 4 indicating moderate to severe pain severity.
Time frame: post-treatment (~4 months after randomization); 6-month follow-up (~10 months after randomization)

The PEG-3 will assess pain severity and related functioning and quality of life (enjoyment, general activity), using a 0 to 10 rating scale with qualifying statements for each numeric rating; a rating of 4 or greater indicates moderate-to-severe pain intensity. The PEG-3 will be included in the Ecological Momentary Assessment (EMA) surveys; Veterans will be asked about the extent to which they have experienced each item in the one hour prior to survey completion. The PEG-3 has been validated in Veterans receiving VA primary care services and has good reliability and validity when compared to longer pain assessments. As a secondary outcome, changes in the Pain severity item will be examined.
