Guided by extensive prior work, the investigators have designed an innovative mHealth behavioral pain coping skills training (PCST) intervention to reduce pain and disability in cancer patients in medically underserved areas (mPCST-Community). Our prior work has tested PCST protocols through in-person sessions at major medical centers where resources and literacy levels are relatively high. mPCST-Community is different and innovative; it uses mHealth technology (e.g., videoconferencing) to decrease access barriers for patients in medically underserved areas. The protocol is brief (4 sessions) and delivered in the community clinic by a remote well-trained pain therapist. Importantly, this protocol has been carefully adapted for low literacy patients.Beverly Thorn, PhD, a nationally recognized expert in strategies for adapting pain coping interventions to low literacy, medically underserved patients, was instrumental in developing the mPCST-Community protocol. mPCST-Community extends to the patient's daily life through use of a simple mobile application that provides low literacy text/audio protocol summaries, relaxation audio, daily assessment and personalized feedback, and coping messaging. The investigators propose a randomized controlled trial (RCT) to test the efficacy of the developed mPCST-Community protocol in breast cancer patients with pain receiving cancer care in medically underserved areas (N=180). The investigators have done careful and extensive pilot work to prepare for the proposed trial. Our pilot work (Journal of Psychosocial Oncology) was conducted in breast cancer patients with pain in three medically underserved rural community clinics. First, focus group data (3 groups; n=19) were used to further refine the adapted protocol. Second, the mPCST-Community protocol was evaluated in a single-arm trial with 20 patients. The invesitgators found high feasibility (i.e., recruitment met), low attrition and high adherence (90% completion), and high acceptability. Importantly, impressive and positive pre- to post-intervention changes were found for pain severity (t=-2.52, p=0.01,gav=0.62; 30% change), pain interference (t=-2.62,p=0.01, gav=0.62), and self-efficacy for pain management (t=3.57, p=0.0004, gav=0.98; 30% change).8Study specific aims are: Aim 1:Test the extent to which mPCST-Community reduces breast cancer patients' pain severity (primary outcome), pain interference, fatigue, physical disability, and psychological distress. Hypothesis:mPCST-Community will lead to decreases in these pain-related outcomes compared to a Health-Ed control condition. Aim 2:Examine mediators through which mPCST-Community leads to benefits. Hypothesis:The effects of mPCST-Community on pain severity, pain interference, fatigue, physical disability, and psychological distress will be mediated by increased self-efficacy for pain management and decreased pain catastrophizing. Aim 3:Evaluate the cost and cost-effectiveness of mPCST-Community. Hypothesis: mPCST-Community will be cost-saving or cost effective in terms of its incremental cost per quality-adjusted life-year from a societal perspective, inclusive of healthcare, intervention and patient-time costs. Its sustainability will be further demonstrated by documenting successful accrual, retention, and protocol adherence.
