Question

Score:/16 Aa Aa 2. Part IV, Problem 2 Loss of hearing can be a significant problem for older adults. Although hearing aids can correct the physical problem, people who have lived with hearing impairment often develop poor communication strategies and social skills. To address this problem, a home education program has been developed to help people who are receiving hearing aids for the first time. The program emphasizes communication skills. To evaluate the program, overall quality of life and satisfaction were measured before treatment, again at the end of the training program, and once more at a 6-month follow-up. [Kramex, S. E., Allessie, G. H. M., Dondorp, A. W., Zekveld, A. A., & Kapteyn, T. S. (2005). A home education program for alder adults with hearing impairment and their significant others: A randomized evaluating short- and long-term effects.
