Self-Affirmation Intervention After Mastectomy

January 12, 2026 updated by: BARIŞ ÖZDERE, Muş Alparslan University

The Effect of Self-Affirmation Skills on Pain, Depression, Anxiety, and Stress in Patients Undergoing Mastectomy: A Randomized Controlled Trial

This randomized controlled trial aims to evaluate the effect of a structured self-affirmation intervention on pain, depression, anxiety, and stress levels in patients undergoing mastectomy. The study will be conducted in two parallel groups, with the intervention group listening to an audio recording of positive self-affirmation statements. Primary outcomes will be assessed using the Visual Analog Scale and the Depression Anxiety Stress Scale (DASS-21). The goal is to provide evidence-based strategies to reduce psychosocial burden after mastectomy.

Study Overview

Detailed Description

This randomized controlled trial is designed to evaluate the effect of a structured self-affirmation intervention on pain, depression, anxiety, and stress levels in patients undergoing mastectomy. Breast cancer is the most commonly diagnosed cancer among women worldwide, and mastectomy, a standard surgical treatment, often results in significant physical and psychosocial consequences. The loss of a breast, perceived as a symbolic part of femininity, can severely impact body image and self-esteem, leading to psychological distress symptoms such as depression, anxiety, and stress, as well as chronic pain. These adverse effects not only reduce quality of life but also negatively influence treatment adherence and long-term survival.

In this study, participants in the intervention group will listen to an audio recording containing positive self-affirmation statements accompanied by soothing background sounds such as birds chirping and flowing water. The recording, prepared by a certified practitioner, lasts approximately 5 minutes and 40 seconds. Patients will be instructed to listen to the recording at least once daily, with encouragement to listen more frequently if desired. The control group will receive standard care without any additional intervention. Primary outcomes will be assessed using the Visual Analog Scale (VAS) for pain and the Depression Anxiety Stress Scale (DASS-21) for psychological distress. The ultimate goal of this trial is to develop an evidence-based nursing and psychosocial support protocol that can be integrated into postoperative care to reduce psychosocial burden and improve well-being in mastectomy patients.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control Group (Standard Care)
Participants in the control arm will receive standard postoperative care according to hospital protocols. No additional behavioral or psychological intervention will be administered.
Experimental: Intervention Group (Self-Affirmation Audio)
Participants in the intervention arm will receive a behavioral intervention consisting of an audio recording of positive self-affirmation statements accompanied by calming background sounds (birds chirping and flowing water). The recording lasts approximately 5 minutes and 40 seconds and will be delivered via an MP3 player and headphones. Patients will be instructed to listen to the recording at least once daily during the postoperative period, with encouragement to listen more frequently if desired.
