ABSTRACT |
Successful auditory rehabilitation programs involve satisfaction measures for clients. The final outcomes may eventually lead to
either satisfaction or dissatisfaction. It is critical in rehabilitation programs to predict the subjective measures in appropriate time
intervals so that individual programs may be modified for better performances. However, reliable quantitative protocols serving these
purposes have been limited in number and practice. In this study, an effective model of estimating satisfaction measures was
developed to describe future outcomes of the programs. This modeling process was based on stochastic Markov process where the
previous state was related to the next state. In this model, transient probabilities were computed to address individual states in session
numbers of a rehabilitation program. The model was applied in a sample group of old adults (N = 12) wearing hearing aids with
similar unaided scores of PTA and WRS to observe the estimated properties of satisfaction. The results showed that the asymptotic
value of satisfaction was reached under the given condition as the session number was increased. With these data, the prospective
outcomes of the program can be monitored for its overall efficacy. The protocol may also contribute to optimizing evaluation and
management to facilitate the rehabilitative process. |
