What this trial studies

This randomized, multicenter trial compares a nine‑week MAEva program to a nine‑week active discussion group in patients treated for non‑metastatic breast cancer. Participants are randomized to attend one weekly 1.5‑hour session for nine consecutive weeks of either MAEva (mindfulness, acceptance, and values‑based commitment exercises) or a discussion group. Quantitative measures of quality of life and psychological well‑being are collected at baseline and follow‑up to compare outcomes between groups. Eligible participants must be able to attend in‑person sessions and have no major psychiatric, cognitive, or sensory impairments that would prevent participation.

Who should consider this trial

Good fit: Ideal candidates are adults treated for non‑metastatic breast cancer who can attend weekly 1.5‑hour in‑person sessions, provide informed consent, and do not have major psychiatric, cognitive, or sensory impairments.

Not a fit: Patients with metastatic disease, acute psychiatric disorders, significant cognitive or attentional deficits, deafness, or those already participating in another mindfulness program are unlikely to benefit or may be ineligible.

Why it matters

Potential benefit: If successful, the MAEva program could improve psychological well‑being and overall quality of life after treatment for non‑metastatic breast cancer.

How similar studies have performed: Previous studies of mindfulness- and Acceptance and Commitment Therapy–based programs in cancer populations have shown improvements in distress and quality of life, and an initial feasibility study of MAEva found it acceptable though larger randomized evidence is still needed.
