Improving emotion regulation in breast cancer patients in the early survivorship period: Efficacy of a brief ecologically boosted group intervention

Abstract

AbstractPurposeThis study reports the short‐ and mid‐term benefits of an eight‐session emotion and self‐regulation group intervention ecologically boosted through daily app‐based prompts. The intervention was designed for breast cancer patients in the early survivorship period meeting criteria for clinical levels of psychological symptoms.MethodsPatients were randomly assigned to the immediate intervention arm (n = 61; intervention received immediately) or to the delayed intervention arm (n = 59; intervention received 5 months later). Psychological symptoms, including anxiety, depressive symptoms, emotional distress, fear of cancer recurrence (FCR), worry, and intrusive thoughts were assessed through questionnaires. Emotion regulation was assessed in a dynamic emotion regulation task and in everyday life. Assessments were completed at baseline (T1), 5 months (T2) and 10 months (T3) later.ResultsTreated patients reported lower levels of worry and intrusive thoughts. They improved their ability to down‐regulate the intensity of their negative emotions when exposed to cancer‐related triggers in the dynamic emotion regulation task. They reported fewer and less intense negative emotions and more positive emotions in their everyday life. Benefits were maintained 5 months later, except for positive emotions in everyday life.ConclusionsThe results showed that focusing on emotion regulation is a relevant approach in the treatment of psychological symptoms for breast cancer patients in the early survivorship period meeting criteria for clinical levels of psychological symptoms. The intervention led to changes in patients' dynamic and everyday life emotion regulation. Consolidation sessions may be needed to sustain benefits in positive emotions and to increase the effect sizes.
