Telephone-Based Rehabilitation Intervention to Optimize Activity Participation After Breast Cancer: A Randomized Clinical Trial.

Importance: Following treatment, breast cancer survivors face challenges participating in valued activities. Objective: To determine whether a telephone-based coaching rehabilitation intervention enhances activity participation in the year following breast cancer treatment. Design, Setting, and Participants: In this multisite, single-blind randomized clinical trial (Optimizing Functional Recovery of Breast Cancer Survivors), recruitment occurred between August 28, 2019, and April 30, 2022. Data collection was completed by April 1, 2023. Participants were recruited from 2 cancer centers (Dartmouth College and the University of Alabama at Birmingham) and via social media advertisements. Women aged 18 years or older who had completed primary treatment for stage I to III breast cancer within 1 year and reported participation restrictions were eligible to participate. Randomization was stratified by site, treatment, and time since treatment. Interventions: The intervention, delivered via telephone over 9 sessions, used behavioral activation and problem-solving principles to promote activity participation. The education-based attention control condition was delivered via telephone at matched intervals. Main Outcomes and Measures: The primary outcome was participation, assessed using 5 measures, including Patient-Reported Outcomes Measurement Information System (PROMIS) social participation-satisfaction measure. One individualized outcome allowed participants to specify activities for which they wanted to foster recovery. Outcomes were collected by telephone by blinded coordinators at baseline and at 8, 20, and 44 weeks. The individualized outcome was assessed at the first and last intervention and control session. Results: Among 1996 patients identified, 303 were eligible and enrolled. Of these, 284 women (94%; mean [SD] age, 56.1 [10.2] years) completed baseline assessments and were randomized, and 81% or more of each group completed the final assessment with no adverse events. Of those who completed the final assessment, 118 of 114 (82%) were in the intervention group, and 113 of 140 (81%) were attention control participants. Between-group differences were not statistically significant for the main measures of PROMIS satisfaction (week 20: Cohen d, 0.1 [95% CI, -0.09 to 0.29] and week 44: Cohen d, -0.08 [95% CI, -0.27 to 0.11]) and ability (week 20: Cohen d, 0.15 [95% CI, -0.06 to 0.37] and week 44: Cohen d, -0.08 [95% CI, -0.27 to 0.11]). On the individualized outcome, intervention participants reported significantly greater improvements in activity satisfaction (Cohen d, 0.76 [95% CI, 0.48-1.02]) and performance (Cohen d, 0.60 [95% CI, 0.32-0.87]). Conclusions and Relevance: In this randomized clinical trial, the intervention catalyzed greater improvements in self-selected activity participation and goal disengagement but did not otherwise accelerate recovery compared with the control condition. Future research should determine what intervention features may lead to the greatest reductions in participation restrictions and other measures that may detect functional recovery.

A Process Evaluation of Intervention Delivery for a Cancer Survivorship Rehabilitation Clinical Trial Conducted during the COVID-19 Pandemic.

The purpose of the present study was to conduct a process evaluation of intervention delivery for a randomized controlled trial (RCT) conducted during the COVID-19 pandemic (NCT03915548). The RCT tested the effects of a telephone-delivered behavioral intervention on changes in breast cancer survivors' satisfaction with social roles and activities, as compared to an attention control condition. This process evaluation examined (a) fidelity monitoring scores; (b) participants' perceived benefit ratings for gaining confidence, reducing distress, adjusting habits and routines, setting goals, and increasing exercise; and (c) field notes, email communications, and transcripts of coach supervision and debriefing sessions. The behavioral and attention control conditions were delivered with a high degree of fidelity (global quality rating score for the BA/PS condition was M = 4.6 (SD = 0.6) and M = 4.9 (SD = 0.3) for the attention control condition, where "5" is the highest rating). The behavioral intervention participants perceived greater benefits than the control participants pertaining to goal setting, t(248) = 5.73, p = <0.0001, adjusting habits and routines, t(248) = 2.94, p = 0.0036, and increasing exercise, t(248) = 4.66, p = <0.0001. Moreover, coaches' perceptions regarding the behavioral intervention's therapeutic aspects aligned with the study's a priori conceptual model including the use of a structured process to set small, observable goals and facilitate the independent use of problem-solving skills. However, coaches also noted that aspects of the attention control condition, including the perceived relevance of the educational content and opportunities for social support, may have made it more therapeutically potent than intended. The pandemic may have affected the activity goals behavioral intervention participants could set as well as augmented the relevancy of social support provided in both conditions.

Study protocol for a multisite randomised controlled trial of a rehabilitation intervention to reduce participation restrictions among female breast cancer survivors.

INTRODUCTION: Many breast cancer survivors report an inability to fully participate in activities of daily living after completing cancer treatment. Reduced activity participation is linked to negative consequences for individuals (eg, depression, reduced quality of life) and society (reduced workforce participation). There is currently a lack of evidence-based interventions that directly foster cancer survivors' optimal participation in life roles and activities. Pilot study data suggest rehabilitation interventions based on behavioural activation (BA) and problem-solving treatment (PST) can facilitate post-treatment role resumption among breast cancer survivors. METHODS AND ANALYSIS: This protocol describes a multisite randomised controlled trial comparing a 4-month long, nine-session BA and PST-informed rehabilitation intervention (BA/PS) against a time-matched, attention control condition. The overall objective is to assess the efficacy of BA/PS for enhancing breast cancer survivors' activity participation and quality of life over time. A total of 300 breast cancer survivors reporting participation restrictions after completing curative treatment for stage 1-3 breast cancer within the past year will be recruited across two sites (Dartmouth-Hitchcock Medical Center and University of Alabama at Birmingham). Assessments are collected on enrolment (T1) and 8 (T2), 20 (T3) and 44 (T4) weeks later. ETHICS AND DISSEMINATION: Study procedures are approved by the Committee for the Protection of Human Subjects at Dartmouth College, acting as the single Institutional Review Board of record for both study sites (STUDY 00031380). Results of the study will be presented at national meetings and submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03915548; Pre-results.
