汉语普通话言语失用症评估诊断工具的编制与验证OA

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.
