Validity and reliability of the questionnaire that measures the perception of speech-language-hearing therapists regarding the use of information and communication technologies (ICTs) in speech-language-hearing evaluation and intervention processes

ABSTRACT Purpose: to study the validity and reliability of the questionnaire that measures the perception of speech-language-hearing therapists, regarding the use of information and communication technologies (ICTs) in evaluation and intervention processes. Methods: a descriptive, cross-sectional, observational, nonexperimental study. A total of 123 professionals from the Region of Valparaíso, Chile, with degrees in speech-language-hearing therapy, participated in the study. They answered the questionnaire that measures their opinion and knowledge on the use of ICTs. Results: the questionnaire had an adequate level of stability, as the Cronbach's α and Guttman's λ6 coefficient values were respectively 0.85 and 0.95. When studying each item, adequate levels of stability were obtained. On the other hand, the corrected homogeneity index (CHI) yielded values lower than 0.2 for items A8, A9, A17, A18, A26, A27, A42, A43, and A46, which suggests not considering them due to a lack of correlation between these items and the overall questionnaire score. Regarding content validity, assessed with the Question Appraisal System, 100% of the questions presented no major semantic problems. Conclusion: the results of the study indicate that the ICT questionnaire is valid and reliable.
