Background and Aim: Stuttering contains speech disruption or observed behaviors and inner reactions of speech- associated or emotional, disruptive, coping, and attitudinal reactions. Inner events can be reported by the person who stutters but can not be reliably defined by listener perceptions. Both the disorder's directly observable and inner elements and their interactive effects need to be fully assessed to achieve to clinically deals. This study investigates validity and reliability of the tests about inner events in stuttering children.
Materials & Methods: This descriptive and analytical study was performed on 96 stuttering and non stuttering students in 6-11 (similar in age and sex). After Persian equalization of questionnaire and verifying, tests validity are scored by 10 experts. In order to tests reliability, children performed tests in two stages (25 days interval). Three methods were used: 1.comparsion between the mean tests scores in two stage 2.Investigation of correlation between two stages. 3. Investigation of results reliability (ICC). The data were analyzed by parametric and non-parametric statistical tests (paired t-test, spearman and pearson).Independent t-test were used in order to compare the mean tests scores between stuttering and non- stuttering children.
Results: Although there was different between the mean BCL and CAT scores of stuttering and non stuttering children but this between group difference is not statistically significant (p>0.05) . The mean BCL and CAT scores between two group (stuttering and non-stuttering) was statistically significant (p<0.05).
Conclusion: Behavioral checklist and communication attitude tests changed in stuttering children at 6-11 age. Both are valid and reliable and these tests distinguish between stuttering and non stuttering children. |
