Abstract

Introduction: Chronic non-specific low back pain (CNSLBP) is one of the leading causes of disability worldwide, significantly impacting quality of life and work productivity. Methodology: This study aimed to perform the face validation of the e-back app, developed to assist the self-management of individuals with CNSLBP through a personalized clinical decision support system. An exploratory mixed-method study was conducted, applying the SUS, uMARS, eHEALS, PAM-13 scales, and structured instruments to a purposive sample of patients, physiotherapists, and IT professionals. Results: The results indicated high acceptability, good usability, and perceived usefulness of the application across all groups, particularly among users with higher digital literacy and health activation levels. Conclusion: the app has potential to be an effective and complementary tool in the management of CNSLBP, aligned with the biopsychosocial model principles.
