Facilitating Adaptive Coping With Fear of Recurrence Among Breast Cancer Survivors

Indiana University390 enrolled

Overview

Fear of cancer recurrence (FCR) is a highly prevalent, disruptive, and under-treated problem for breast cancer survivors. This randomized controlled trial will test the efficacy of group-based Acceptance and Commitment Therapy compared to Cognitive Behavioral Therapy and enhanced usual care for breast cancer survivors suffering from FCR while examining its cost-effectiveness and the mechanisms by which the intervention may work. Study findings will guide the future care of breast cancer survivors with FCR.

The primary objective of this 3-arm randomized control trial (RCT) is to build on the investigators' pilot work by testing the impact of Acceptance Commitment Therapy (ACT) on FCR. The investigators will randomly assign up to 375 early-stage Breast Cancer Survivors (BCS; for at least 300 study completers after attrition) who have finished primary cancer treatment and who report clinically significant FCR to: (1) group-based ACT (6 weekly 1.5-hour videoconference sessions), (2) group-based Cognitive Behavioral Therapy (CBT; 6 weekly 1.5-hour videoconference sessions), or (3) Enhanced Usual Care (EUC; a single 90-minute videoconference coaching session with self-administered readings). Outcomes will be assessed at baseline and at 2, 6, and 12 months; additionally, potential theory-driven mediators of the ACT intervention's effects on key outcomes will be analyzed at these time points and at intervention midpoint. Cost-effectiveness of each intervention will be assessed. Specific Aims are to: (1) test the efficacy of group-based ACT compared to CBT and EUC on FCR (primary outcome) and anxiety, depressive symptoms, post-traumatic stress, avoidant coping, fatigue, sleep disturbance, and quality of life (secondary outcomes) in BCS with clinical FCR; (2) to examine changes in psychological flexibility as a mediator of ACT's effect on FCR; and (3) to perform comparative assessments of ACT, CBT, and EUC to determine the cost-effective intervention.

Interventions

Enhanced Usual CareBEHAVIORAL

Interventionists will provide a brief explanation of the intervention and coaching to the group on how to utilize the resources provided. Prior to the single session group, EUC participants will have received a workbook with the National Cancer Institute's "Facing Forward: Life After Cancer Treatment" booklet on maximizing quality of life during cancer survivorship and the American Society of Clinical Oncology's "Guide to Cancer Survivorship."

Acceptance Commitment TherapyBEHAVIORAL

Interventionists will support participants in adopting a psychologically flexible posture toward FCR through six interdependent processes of change - acceptance, cognitive defusion, mindfulness, perspective taking, values, and committed action. During ACT sessions, participants will learn to respond adaptively to FCR by being more fully aware of thoughts, feelings, and bodily sensations without judging or attempting to control or avoid them. Participants will also clarify their deeply-held values and set action goals in alignment with their values.

Cognitive Behavioral TherapyBEHAVIORAL

Interventionists will provide psycho-education on the cognitive behavioral model of FCR and assist participants in changing unhelpful thinking patterns and maladaptive behaviors linked to FCR. Session topics will include FCR triggers, behavioral experiments to reduce FCR-perpetuating safety behaviors, and pleasant events scheduling. Interventionists will also provide evidence-based information on behaviors that may reduce recurrence risk (e.g., achieving a healthy weight, physical activity, cancer surveillance).

Outcomes

Primary Outcomes

Change in Fear of Cancer Recurrence from Baseline

The 43-item Fear of Cancer Recurrence Inventory (FCRI) includes triggers, psychological distress, coping strategies, reassurance seeking, insight, severity, and functional impairments subscales. Each item is rated on a scale from 0 (never, not at all, or I don't think about it) to 4 (all the time or a great deal), participants indicate the extent to which they are fearful, with higher scores indicating greater FCR.

Time frame: given at baseline (T1), intervention midpoint (T-Mid), 2 months post-baseline (T2), 6 months post-baseline (T3), and 12 months post-baseline (T4)

Secondary Outcomes

Change in Fear of Cancer Recurrence Questionnaire - 7 (FCR-7) from Baseline

The 7-item FCR-7 assesses anxiety, worry, and strong feelings associated with cancer recurrence, coupled with items assessing cognitive and behavioral responses to FCR. The first six items are on a scale from 1 (not at all) to 5 (all the time). The seventh item assesses the extent to which worry about getting cancer again intrudes on thoughts and activities on a 0 (not at all) to 10 (great deal) scale. Higher scores indicate greater FCR.

Fear of Cancer Recurrence Global Anchor

Participants will be asked "Overall, since starting your assigned study program, is your fear of cancer recurrence worse, about the same, or better?" Those rating their fear of cancer recurrence as "better" are then asked if their fear is "a little better," "somewhat better," "moderately better," "a lot better," or "completely better".
