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.

摘要
研究目的：探讨用于测量言语语言治疗师对信息与通信技术（Information and Communication Technologies，ICTs）在评估与干预流程中应用感知的问卷的效度与信度。
研究方法：本研究为描述性、横断面观察性非实验研究。共计123名来自智利瓦尔帕莱索地区的言语语言治疗专业从业者参与本次研究，受试者填写了用于评估其对ICT应用的认知与看法的问卷。
研究结果：该问卷具备良好的稳定性，克朗巴哈α系数（Cronbach's α）与古特曼λ6系数（Guttman's λ6）分别为0.85与0.95。对各条目单独分析后，亦获得了良好的稳定性水平。另一方面，校正同质性指数（corrected homogeneity index，CHI）显示条目A8、A9、A17、A18、A26、A27、A42、A43及A46的数值均低于0.2，提示由于此类条目与问卷总分间相关性不足，应考虑将其剔除。就内容效度而言，采用问卷评价系统（Question Appraisal System）进行评估后，100%的条目未出现显著语义问题。
研究结论：本研究结果表明，该ICT相关问卷具备良好的效度与信度。
