Narrative skills of children treated for brain tumours: The impact of tumour and treatment related variables on microstructure and macrostructure

摘要

Objective: The narrative skills of children with brain tumours were examined. Influence of tumour location, radiotherapy, time post-treatment and presence of hydrocephalus was also investigated, as well as associations between narrative and language abilities.Method: Seventeen children (aged 5;6-14;11) treated for brain tumour and their matched controls completed a narrative assessment and comprehensive language testing. Audio recorded narratives were analysed for microstructure and macrostructure elements. Between-group comparisons were conducted. Narrative elements were explored in association with tumour and treatment-related variables. Correlation analysis examined relationships between narrative scores and language test performance.Results: While significant differences were not found between two groups of children across narrative elements, sub-group comparisons revealed marginal differences in macrostructure related to tumour location and hydrocephalus. Children treated with methods other than radiotherapy showed a significant increase in number of mazes in their narratives compared to children who received radiotherapy. Strong positive correlations also existed between narrative elements and language performance.Conclusion: Preliminary findings highlight the importance of investigating narrative abilities as part of a comprehensive language assessment. Macrostructure should be routinely examined where children are diagnosed with either posterior fossa tumour or hydrocephalus or have undergone surgery and/or chemotherapy for brain tumour.
