| dc.description.abstract | This study aimed at comparing the phonological changes obtained in the different models of
therapy in subjects with different degrees of phonological disorder (PD) severity. The PD
diagnosis was determined out by means of phonological and complementary assessments. The
subjects’ speech data were analyzed through the performance of the Child’s Phonological
Assessment (CPA) proposed by Yavas, Hernandorena & Lamprecht (1991). After the
phonological assessment, the percentage of correct consonants (PCC) proposed by Shriberg &
Kwiatkowski (1982) was calculated and the subjects were then classified in the degrees of
severity of the PD: severe (SD), moderate-severe (MSD), mild-moderate (MMD) and mild
disorder (MD). The data utilized in the study to belong three Master’s Dissertations (Blanco,
2003; Barberena, 2005; Bagetti, 2005) had aimed at comparing, in subjects with different
degrees of PD severity, the generalization obtained with treatment, respective by Modified
Cycles, ABAB-Withdrawal and Multiple Probes and Modified Maximum Opposition Models.
The studied group was composed by twenty one subjects, eleven males and ten females, with
average age in the beginning of treatment 5:7. After the treatment, making the comparison
among models of therapy within each degree of PD severity of the PCC, phonetic inventory,
phonological system and generalization. The following types of generalizations were
analyzed: to non used items during treatment (other words); to other position in the word,
inside a sound class; and to other sound class. The types of generalizations were found in all
models researched, however, the subjects treated with ABAB-Withdrawal and Multiple
Probes presented the major phonological changes in relation to the generalization to non used
items during treatment (SD, MSD, MMD), to generalization inside a sound class (MMD,
MD) and to other sound class (SD, MSD, MMD, MD). Also the subjects treated with the
Modified Maximum Opposition Model presented generalization to non used items during
treatment (MD) and to other position in the word (MSD, MMD). Concerning the PCC,
phonetic inventory, phonological system was verified gains in all models studied, but the
ABAB-Withdrawal and Multiple Probes and Modified Maximum Opposition Models were
more effetive to the group with MSD and the ABAB-Withdrawal and Multiple Probes to the
group with SD. | |
