Summary
This study presents a data-driven process to predict mood in breast cancer patients using mobile app engagement metrics. The findings show that combining engagement and survey data with a random forest classifier accurately predicts mood, aiding personalized cancer care.
Area of Science:
- Digital mental health
- Oncology
- Psychometrics
Background:
- Mobile health interventions are crucial for managing cancer treatment side effects.
- Understanding the link between patient mood and app engagement is vital for treatment success.
- A data-driven approach is needed to analyze mood and app engagement in cancer patients.
Purpose of the Study:
- To outline a step-by-step process for predicting mood in breast cancer patients using app engagement data.
- To demonstrate the application of this process using data from a mobile mental health app.
Main Methods:
- Data preprocessing, feature extraction, and predictive modeling were employed.
- Engagement patterns were compared between patients with high/low anxiety and depression.
- Random forest and XGBoost classifiers were evaluated for mood prediction accuracy.
Main Results:
- Engagement patterns differed between high and low anxiety/depression groups.
- Predictive models showed varying accuracy; the best model achieved 84.6% accuracy.
- A combination of survey and app engagement features with a random forest classifier yielded the highest performance.
Conclusions:
- The developed analytic process is feasible for understanding mood and app engagement in breast cancer patients.
- Predicting mood using self-report and engagement features can improve clinical decision-making.
- This approach supports the development of personalized digital mental health interventions for cancer patients.
