ABSTRACT
Evaluation of voice problem involves perceptual, acoustic, aerodynamic and physiological measure. In recent years assessment of patients point of view use as a essential part of evaluation. The aim of this study was construct a questionnaire for assessment of physical, functional and emotional voice problems in adults. This study is a kind of constructing battery. Based on a comprehensive study of many foreign questionnaires, "The voice symptoms assessment" questionnaire in adult was produced. Its content validity was determined according to the judgment of 7 speech and language pathologists. This questionnaire administered to 60 voice patients [20 female and 40 male] between 18 to 60 years old that could read and write in Persian. The reliability of this questionnaire is determined by the method of Cronbach Alpha and split half. Content validity index of this questionnaire was 0.94. Cronbach Alpha was high [more than 0.7] and Spearman-Brown coefficient of split half was 0.96. Correlatoin Coefficient was statistically significant between 3 parts and total questionnaire [p<0.01]. "The voice symptoms assessment" questionnaire in adult has good content validity and reliability and reflects the wide range of physical, functional and emotional problems in voice patients. This questionnaire is simple for patients to complete and easy to score. It seems that use of this questionnaire, as part of a complete voice evaluation will be helpful in future.
ABSTRACT
Speech intelligibility is defined as a measure of effectiveness of understanding speech. It has many applications such as nomination of speech disorder intensity. Different methods and speech tasks have been designed for assessment of speech intelligibility amongst which word identification tasks have high validity. This study aimed to provide a test to measure speech intelligibility among children aged 3 to 5 years old. Many words were collected and content validity was assessed by 9 speech-language pathologists and 1 linguist. Thirty four words with a content validity above 70% were chosen as the test words and the speech-language pathologists collected suitable pictures for the words. One hundred boys and girls aged 3 to 5 years participated in the study. Inter-rater reliability was administered to assess the test reliability. An interclass correlation coefficient of 0.85 and spearman correlation coefficient of 0.81 was obtained for the speech intelligibility test. Speech intelligibility test has appropriate validity and reliability and is suitable for assessment of intelligibility in 3 to 5 years old children
