| Abstract | |
Currently, the applicability of motivation tools has been effective in encouraging the process of behavioral change. This study aimed at developing a scale based on the University of Rhode Island Change Assessment Scale (URICA) to characterize the motivational stages of change to be used in the population of adults and elderly people presented with hearing impairment (HI). The study comprised: pilot group (PG): 17 users of hearing aids (HA); focal group (FG): 9 users of HA and 8 candidates for HA; study group (SG): 200 candidates for HA. Initially, URICA was adapted to assess patients presented with HI, being appreciated by the judges. In PG, from the application and comprehension of the patients on the scale, appropriate amendments were made and sent to one of the authors of the original scale who suggested that some items be reviewed, as well as a study with a group of patients so as create a tool which took into account the perception of the patient, from his/her perception while dealing with the impairment. Thus, the FG strategy was established so as to choose statements which made more sense to patients in each stage experienced, resulting in the final version of the scale, which was applied to SG. The factorial analysis through Main Components Analysis, Cronbachs alpha coefficient, verified the internal consistence of the tool, the convergent validation of the instrument through comparison with the Readiness Scale and the comparison of demographic data, hearing impairment and HA of patients with the scale, by adopting a 5% significance level. Following the analysis of the Main Components and Cronbachs coefficient, the scale was reduced from 34 to 25 items, with a good internal consistency (0.813) and better grouping into 3 factors: stages of action-maintenance, contemplation-preparation, pre-contemplation having a good discrimination. Most candidates for HA are in the stages of contemplation and preparation and the users of HA, action. Convergent validation indicated that despite the weak correlation, p was statistically significant in the 5 stages. When compared, the stages showed a significant correlation in the contemplation and preparation, action and maintenance and pre-contemplation and preparation. As to the predictive validity of the scale, there was a significant difference between the time of HA use and the stages of contemplation, action and maintenance, between the degree of hearing impairment and the stage of maintenance, between the type of HA and the stage of maintenance, between education and the stages of contemplation and preparation and between the socio-economic classification and the stages of precontemplation and preparation. Further studies to improve the tool and provide it with a better factorial dimension, are necessary. (AU) | |
