Abstract:
Objective To compare the application of main concept analysis(MCA)and story narration as-sessment(SNA)in aphasia discourse assessment,and study their clinical applicability.Methods A total of 8 apha-sic and 22 healthy control subjects were recruited.Local sequential picture materials were used to elicit language samples.The differences between groups in the assessment results of the MCA and the SNA were compared,the consistency of the assessment results of the two methods were also analyzed.The inter-rater and the intra-rater reli-ability of the two methods was discussed.Results The results of the MCA showed that the number of accurate and complete(AC)main concepts(P＜0.01),the number of accurate and complete main concepts per minute(AC/min)(P＜0.05)and main concept scores(MC scores)(P＜0.05)of the aphasia group were significantly lower than those of the healthy group.The number of absent(AB)main concepts(P＜0.05)were significantly higher than those of the control group.As for the result of SNA,the score of the content of sub picture description(P＜0.05),the total score of sub picture description(P＜0.05)and the total score of overall description(P＜0.05)in the aphasia group were significantly less than those in the control group(P＜0.05).No significant difference be-tween the standardized scores of the two methods were observed,and inter-rater and the intra-rater reliability were both in a good range.Conclusion The clinical applicability of the two methods is excellent and the evaluation results are conststent.The MCA has outstanding advantages in evaluating the quality and quantity of information,while SNA examines the syntax and content organization,which can reflect the overall discourse performance.
