Distanslevererad Kognitiv Beteendeterapi Stresshantering för Bröstcancer (R-CBSM)

Subjects in this group will receive 10 weeks of group R-CBSM intervention convened by a broadband connection for approximately 75 - 90 minutes at a mutually convenient time plus a standard of care survivorship care planning.

Participants will receive the remotely delivered "telehealth" Cognitive Behavioral Stress Management (CBSM) intervention, consisting of 10 weeks of structured group sessions. The program will include core CBSM components such as cognitive restructuring, relaxation training, coping skills development, and strategies for managing stress-related thoughts and behaviors. Sessions will be conducted via a secure broadband connection and will last approximately 75-90 minutes, scheduled at a mutually convenient time for group members. Prior to beginning the intervention, each participant will complete a 30-minute individual orientation call. This session will provide instructions on how to join and participate in the group meetings remotely using videoconferencing on a handheld device, laptop, desktop computer, or mobile phone. The orientation will also familiarize participants with the technology, group procedures, and expectations to ensure smooth engagement throughout the program.

Participants will receive the Standard of Care Survivorship Care Planning that includes a 30-minute orientation call to provide them with information on Survivorship Care Planning (SCP) and answer any questions they may have. The SCP being used in the proposed study will use a prospective preparation of the treatment summary and care plan. The SCP is designed to facilitate access to resources provided by our cancer center's survivorship program (e.g., nutritional, exercise physiology, music therapists, acupuncture) which we will monitor for use. The SCP is based on templates for breast cancer survivorship employed at the Sylvester Comprehensive Cancer Center (SCCC) Breast Survivorship Program and includes access to cancer survivorship resources, which is the standard of care control condition.

Participants in this group will receive the standard of care survivorship care planning (SCP) only. Each participant will have a 30-minute orientation call to provide them with information on Survivorship Care Planning (SCP) and answer any questions they may have.

Cancer-specific intrusive distress will be measured using the 7-item Intrusion subscale of the Impact of Event Scale (IES). Each item is scored 0 ("not at all"), 1 ("rarely"), 3 ("sometimes"), or 5 ("often"), yielding a total score range of 0-35. Scores reflect the frequency of intrusive, cancer-related thoughts over the past 7 days. Higher scores indicate greater intrusive distress, and lower scores indicate fewer intrusive thoughts and better psychological adaptation. Change scores will be calculated as slope of change over 3 time points (baseline, 6months, and 12 months). Negative slops indicate improvement (reduced intrusive distress), and positive values indicate worsening. Change scores (slopes) will be compared between the R-CBSM+SCP and SCP-only arms to evaluate whether the combined intervention produces greater improvement over 6 and 12 months.

Change in immune cell senescence will be measured using latent construct composite of B- and T-lymphocyte metabolic indicators (ATP production, maximum respiration, and spare respiratory capacity). A composite score will be created from ATP production, maximum respiration, and spare respiratory capacity to index lymphocyte hyper-metabolism, a marker of cancer-accelerated aging. Higher composite values indicate greater immune senescence. Composite change scores (slope of change over the 4 time points) will be compared between study arms, R-CBSM+SCP and SCP only, over 6- and 12-months Increases indicate worsening immune senescence while decrease indicate lessening immune senescence.

Change in neuroendocrine regulation assessed using a latent construct composite of 24-hour salivary cortisol area-under-the-curve (AUC), 24-hour salivary cortisol diurnal slope, and 4-day average heart rate variability (HRV). A standardized composite score will be created from cortisol AUC, cortisol diurnal slope, and 4-day average HRV to index neuroendocrine stress regulation. Increases in any of these indicators is associated with increased stress and greater neuroendocrine dysregulation. Change scores (slope of change over the 3 time points) will be compared between study arms. Increases in slope indicate worsening neuroendocrine dysregulation/stress while slope decreases indicate lessening neuroendocrine dysregulation/stress.

Change in depression severity will be measured using a latent construct composite of self-report and clinician-rated measures of depression: the Center for Epidemiologic Studies Depression Scale (CES-D), the Hamilton Rating Scale for Depression (HRSD), and depressive diagnoses from the Structured Clinical Interview for DSM-5 (SCID-5). A standardized composite score (e.g. Z score) will be created from CES-D total scores, HRSD clinician-rated severity scores, and SCID-5 depressive episode diagnoses to index overall depression severity. Higher composite values indicate greater depressive symptom burden. Change scores (slope of change over the 4 time points) will be compared between study arms. Increases over time indicate worsening depression while decreases indicate lowering of depression over time.

Change in quality of life will be measured using the patient-reported Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaire. Quality of life will be measured using the FACT-B, a validated self-report questionnaire assessing physical, social, emotional, functional well-being, and breast cancer-specific concerns. Higher total scores indicate better quality of life. Score Range is 0-148 (higher scores reflect better quality of life). Change scores in total quality of life (slope of change over the 4 time points) will be compared between study arms. Therefore, increases in the slope indicate increasing quality of life while decreases indicate worsening quality of life over time.
