Background: The assessment of narrative skills in young children is essential for early identification of potential learning and literacy-related difficulties. The present study aimed to develop a validated and reliable test for consecutive assessment of narrative skills in Iranian school-age children.
Methods: To elicit story retelling by the children, 14 pictures (each a discrete test) were developed based on which 14 stories were scripted in accordance with the Stein and Glenn model. The pictures were presented to 50 typically developing (TD) children and seven children with autism spectrum disorder (ASD) in Kerman, Iran, 2018. The recorded audio of retold stories by the children was transcribed and analyzed using the monitoring indicator of scholarly language (MISL) instrument. The SPSS software (Version: 18.0) was used to analyze the data with the significance level set at 0.05.
Results: A high correlation between the total MISL score of each test and each MISL item (r>0.5) confirmed the construct validity of our test. A comparison of the mean total MISL score between the TD and ASD groups showed significant differences (P<0.001) for all pictures. The internal consistency coefficient was >0.7 between all the MISL items and the intraclass correlation coefficient between the test and retest scores was >0.96 for all pictures. The repeated measures ANOVA did not indicate significant differences (P=0.15) between the total MISL scores of the pictures.
Conclusion: The validity and reliability of the developed test were confirmed, suggesting it can be used for consecutive assessment and monitoring of the narrative skills in school-aged children.
