Development and validation of assessment and diagnostic tools for apraxia of speech of Chinese Putonghua
摘要
Abstract
Objective To develop an assessment tool for apraxia of speech(AOS)of Chinese Putonghua speakers and test its reli-ability and validity. Methods The Chinese Apraxia of Speech Assessment and Diagnostic Tool(CAADT)was developed based on the Aprax-ia of Speech Rating Scale 3.5,combined with the linguistic characteristics of Chinese and clinical experience.The tool consistsed of eleven items across three sections:articulation,prosody and alternating motion rates.Six experts evaluated the content validity.From November,2024 to May,2025,51 patients with post-stroke AOS(ex-perimental group)and ten patients with post-stroke aphasia without AOS(control group)were recruited from An-hui Wannan Rehabilitation Hospital(the Fifth People's Hospital of Wuhu),and tested with CAADT.Reliability was assessed using Cronbach's α coefficient,Kendall's coefficient of concordance W and Pearson correlation co-efficient.Validity was evaluated using the content validity index(CVI)and Spearman correlation coefficient.Dis-criminative effect was analyzed using the receiver operating characteristic(ROC)curve. Results The Cronbach's α coefficients for the articulation and prosody sections and the total scale were all>0.9,while it was 0.454 for the alternating motion rates.Inter-rater reliability was good(W≥0.598,P<0.001).Test-retest reli-ability showed high positive correlations for the three sections and the total score between the two assessments(r≥0.84,P<0.001).The scale-level CVI was 0.95,and the item-level CVI≥0.83.The Spearman correlation co-efficients among the sections ranged from 0.30 to 0.70.ROC analysis revealed an area under the curve of 0.953,with a cut-off value of 11,yielding a sensitivity of 0.92 and a specificity of 0.90. Conclusion CAADT demonstrates good reliability,validity and discriminative effect,which can be used for clinical as-sessment and auxiliary diagnosis of Chinese Putonghua speaking patients with post-stroke AOS.关键词
