The purpose of this study was to investigate the change in effective commun
ication between parents and children with cochlear implants when the parent
s attended a modified Hanen training course(Watson 1995). The study demonst
rates that the course led to improvement in the effectiveness of the parent
-child interaction, as rated by naive independent observers. The Erber rati
ng scale (Erber et al. 1995) was implemented as a tool for evaluating chang
es before and after the courses. Using video samples taken at the above int
ervals, the ratings showed a significant increase in effective communicatio
n at the end of the courses.
