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

Purpose: This 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.

Methods: Patients 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).
