Abstract
Articulation/phonological disorder is one of the most common child language disorders. The past studies indicated that parents taking part in child language intervention is very crucial. In addition, it is the most efficient that parents participating in helping children with language disorders due to the limited number of speech therapists. With the alternation of early intervention model, parents are no longer passively followed the instruction of therapists, but become more active. Therefore, the motivation of home-program practice will increase as well, which positively influences treatment efficacy. However, there are few studies investigating which parameter of home-program practice is the most impactful for children’s treatment efficacy. Thus, the main focus of this study is medical compliance. This study investigates how the quality(the consistency of home practice and therapist’s advices)and quantity(the frequency and duration of weekly practice) influence treatment efficacy of children with articulation /phonological disorder. This study utilized single-subject experimrntal design. Subjects were 34 parents(32 female, aged 39.44±4.73;2 male, aged 39.0±2.83 )of children receiving articulation treatment. All children take individual articulation treatment class once a week, the home-practice data was collected on the tenth class. The correlation regression analysis results indicated that there are significant correlation(β＝.28, p＝.045) between the frequency of home practice and post-test of percentage of consonants correct (PCC).The quality of home practice(β＝.16, p＝.212), duration of home practice(β＝-.01, p＝.964) have no significant relation between children PCC.
