The SPArKED Instrument: Gathering Validity Evidence for Measuring Digital-Age Lifelong Learning

Introduction: Traditional instruments for measuring lifelong learning of health professionals fail to capture digital-age learning, creating a critical measurement disconnect. To address this gap, we developed a 16-item Self-Pursuits, Aspirations, and Knowledge Endeavors in the Digital Era (SPArKED) instrument. Methods: To gather validity evidence for SPArKED, a cross-sectional survey was deployed to health professional students (n = 558). The survey questionnaire included: SPArKED, Jefferson scale of lifelong learning for students in health professions, basic psychological needs satisfaction scale, and human–computer trust scale assessing students’ trust in generative technology to support lifelong learning. Exploratory factor analysis (EFA) and correlation analysis were performed. Results: The EFA of the SPArKED revealed a three-component structure: networked learning, i-learning (individual mastery), and AI-powered learning, together explaining 55% of the total variance. The SPArKED demonstrated good internal consistency (α = 0.86) and convergent validity with the Jefferson scale of lifelong learning (r = 0.75). The correlations between SPArKED and psychological needs satisfaction scores were moderately high: autonomy (r = 0.50), competence (r = 0.48), and relatedness (r = 0.51). SPArKED had a higher correlation with students’ trust in generative technology to support lifelong learning than the Jefferson scale (r = 0.52 and r = 0.32, respectively). Conclusions: Compared to the Jefferson scale, the SPArKED instrument appears to better capture digital-age learning behaviors among students in health professions. By assessing these evolving behaviors in learners, education programs can better guide future health practitioners in developing desired lifelong learning competencies and digital literacies. Future research should gather validity evidence for SPArKED across diverse learner samples and educational stages, informing a critical re-assessment of established instruments in the rapidly evolving learning landscape.
