The Pain & Stress Interview Study for People With Chronic Pain

This study is a randomized controlled trial to test the efficacy of a brief, one-session therapeutic interview for patients who are seeking biomedical care for their chronic musculoskeletal pain and who also have self-reported trauma histories. Participants will be randomized to either a therapeutic interview condition or a waitlist control condition and and will follow patients for 6 weeks to identify health and attitude changes in response to the interview. This study will recruit adults with chronic musculoskeletal pain and reported histories of childhood adversity. Participants will be adults with primary musculoskeletal pain such as low back pain, neck pain, and fibromyalgia. In addition, only those patients who also report a significant history of childhood adversity will be eligible for this study, as determined by a score of 3 or higher on the Adverse Childhood Experiences (ACE) Scale. Patients will be excluded if they: a) have a current psychotic disorder or b) are unable to communicate in English, or c) are scheduled for an upcoming surgery within the next 2 months. Participants will be allowed to engage in this study regardless of current medication use or engagement in other treatment. Patients who are interested in participating will complete a brief online screening to determine eligibility and will be provided with basic information about the study. Once consented, baseline measures will be completed online, and participants will be randomized, 1:1, to the therapeutic interview condition or waitlist control condition. Those who are randomized to the therapeutic interview condition will complete their interview as soon as possible after completing baseline measures. The interview will be conducted either in-person at the Stress \& Health Laboratory at Wayne State University, or remotely via a secure telehealth platform (depending on COVID-19 restrictions). Follow-up measures will be administered at 6 weeks after the interview (or at the equivalent time for the waitlist group). Participants in the waitlist control condition will be given the opportunity to receive the therapeutic interview after completion of the follow-up measures. The therapeutic interview will be a one-session interview lasting approximately 90 minutes. The interview will be conducted by trained interviewers (i.e., clinical psychology graduate students). The goals of the therapeutic interview are to promote awareness of the role of trauma and interpersonal stress in pain, to encourage experience of emotions associated with interpersonal stressors and conflicts, and to encourage more adaptive interpersonal communication in current relationships. The interview has five primary components. The first component involves eliciting a brief pain history from the participants. The next component explores participants' stressful life experiences, including those that occurred during their childhood and those that might be affecting their current life. The next component will introduce participants to a model of emotions that illustrates how suppressing important, healthy feelings in relationships can lead to symptoms (e.g. anxiety, pain, stress). Participants will be encouraged to identify the feelings that are most difficult for them to express in relationships and the ways in which avoiding these feelings leads to prolonged stress or worse pain. The next component involves encouraging participants to identify key, conflictual relationships and to express their previously avoided, healthy feelings (e.g. assertion, tenderness, grief). The final and 5th component will explore how the interview affected their beliefs about the role of stress and emotions in pain. The interviewer will provide a summary of their strengths and areas for improvement related to their emotions and interpersonal functioning. There will be clinical outcomes that reflect changes in pain severity and pain interference, pain-related anxiety, and emotional distress. There will be behavioral outcomes that capture changes in patients' interpersonal assertiveness, substance use, and adaptive affective functioning (defined as one's cognitive, behavioral, and emotional responses to one's healthy feelings or needs). Finally, there will be attitudinal outcomes that reflect changes in patients' attributions about the role of psychological and brain-based factors in pain.
