Overview

This study will design, test, and evaluate SerenApp, a digital health tool created to support women after completing treatment for breast cancer. Many women live for many years after breast cancer, but a large number continue to experience emotional difficulties such as anxiety, sadness, stress, or fear of the cancer coming back. These problems can strongly affect quality of life and are often not addressed during routine medical visits. SerenApp is being developed as a safe, easy-to-use mobile application that provides psychological support and practical resources to help breast cancer survivors manage these challenges. What makes this project different is that the app will be created together with patients and healthcare professionals, to ensure that it responds to real needs and is adapted to the public health system in Spain. The main questions of the study are: Can SerenApp help women feel less anxious, depressed, or stressed and improve their overall quality of life? Will women and professionals find the app useful, acceptable, and easy to use? Could this digital tool reduce the need for additional healthcare resources and be cost-effective for the health system?

The project has two main parts: Co-creation phase: Women who have had breast cancer and healthcare providers (such as oncologists, nurses, and psychologists) will participate in workshops and group discussions. They will share their experiences, identify needs, and help design the functions and content of the app. This ensures that the final product is adapted to what patients and professionals really want and need. Pilot clinical study: Women who have finished their breast cancer treatment will be invited to join the study. Participants will be randomly assigned to one of two groups: Intervention group: Women will use SerenApp for 8 weeks. The app includes exercises, information, and resources to help manage emotions, improve coping strategies, and feel more in control of their health. Control group: Women will continue with their usual follow-up care. All participants will complete questionnaires at the beginning and end of the study to measure emotional well-being, quality of life, satisfaction with care, and use of healthcare services. After the 8 weeks, some women will take part in group interviews to share their opinions and experiences using the app. By combining patient and professional input with scientific evaluation, this project will test whether SerenApp is a feasible and effective way to provide psychological support to breast cancer survivors. If it works as expected, SerenApp could become a valuable tool for women, families, and health services, offering accessible, evidence-based support to improve emotional well-being after cancer.

Outcomes

Primary Outcomes

Change in Stress Coping Strategies

The CAEPO assesses cognitive and behavioral coping strategies used by oncology patients to manage stress related to their disease. It includes 40 items across seven subscales: Confrontation and Active Fighting, Self-Control and Emotional Control, Seeking Social Support, Anxiety and Anxious Worry, Passivity and Passive Resignation, Escape and Distancing, and Denial. Each item is rated on a 4-point Likert scale (0-3), with higher scores indicating greater use of each coping strategy.

Time frame: Baseline (T0) and 8 weeks (T1)

Change in Anxiety Symptoms

Measured using the Hospital Anxiety and Depression Scale - Anxiety subscale (HADS-A), this outcome evaluates changes in anxiety symptom severity in breast cancer survivors. The HADS-A consists of 7 items rated on a 0-3 Likert scale, with total scores ranging from 0 to 21. Higher scores indicate greater anxiety symptoms.

Time frame: Baseline (T0, before intervention) and 8 weeks post-intervention (T1)

Change in Depressive Symptoms

Depressive symptoms will be assessed with the Patient Health Questionnaire-9 (PHQ-9), a validated 9-item scale widely used in oncology and primary care. Higher scores indicate more severe depression. Total Score: 0-27

Time frame: Baseline (T0) and 8 weeks (T1).

Secondary Outcomes

Change in Health-Related Quality of Life

Measured with the EQ-5D-5L, a standardized instrument for assessing health status across 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression Scale: Each of 5 dimensions rated from 1 (no problems) to 5 (extreme problems) Interpretation: Higher scores indicate better health-related quality of life (better outcome)

Time frame: Baseline (T0) and 8 weeks (T1)

Usability of SerenApp

Measured with the System Usability Scale (SUS), a validated 10-item scale assessing usability and acceptability of digital interventions. Scale: 0-100 Interpretation: Higher scores indicate better usability and acceptability (better outcome)

Time frame: 8 weeks (T1, post-intervention only).

Satisfaction with Care

Measured with the Client Satisfaction Questionnaire-8 (CSQ-8), a validated tool assessing satisfaction with the intervention and overall care. Scale: 1-4 per item across 8 items Total Score: 8-32 Interpretation: Higher scores indicate greater satisfaction with care and the intervention (better outcome)

Time frame: 8 weeks (T1)
