The authors sought to assess the effect of an educational intervention based on the concept of reusable learning objects (RLOs), on knowledge of hearing aids and communication in first-time hearing aid users. The authors utilized a randomized controlled trial of hearing aid users, where one arm received the educational intervention and the other arm acted as a control group. RLOs were delivered through DVD for TV and PC, and online. Knowledge of both practical and psychosocial aspects of hearing aids and communication was assessed using a free-recall method at six-weeks post-fitting. Knowledge of both practical and psychosocial knowledge was significantly higher in those who received the RLOs compared to the control group. Moderate to large effect sizes indicated these differences were clinically significant. The authors concluded that an educational intervention to supplement clinical practice results in improved knowledge in first-time hearing aid users.
