Narration, or storytelling, is an important aspect of language. Narrative skills have practical and social importance; for example, children who tell good stories receive attention and approval from their peers. When children accurately recount events surrounding an injury or dispute, vital information is passed to parents and teachers. Additionally, early childhood narrative skills are moderately correlated with reading comprehension in primary grades. Because narration is socially and academically valued, language interventionists often address it. The research literature on narrative intervention has most often included school-aged participants and those with language or learning difficulties. Only a small number of studies have investigated narrative intervention with preschoolers, and the supporting evidence is suggestive rather than conclusive. Outcomes frequently targeted include narrative story grammar (e.g., character, problem, action, consequence) and general language outcomes (e.g., length of story, mean length of communication unit, and total number of words). Results have been generally positive; however, the methodological quality of studies is poor. Therefore, few firm conclusions can be drawn regarding the efficacy of narrative interventions. Because of its potential and popularity, the effect of narrative intervention on a range of populations needs to be examined systematically through high quality research. This study evaluated the effects of a narrative intervention on story retelling and story generation using a multiple baseline design with five target participants. We delivered narrative intervention in a small group arrangement. Materials, activities, and instructor assistance were adjusted systematically within session to facilitate increasingly independent practice of story retells and personal story generations. Results suggest that narrative intervention improved participants' narrative retell and personal generation performance based on Index of Narrative Complexity (INC) scores. All five target participants made substantial gains in narrative retelling, demonstrated improved pre-intervention to post-intervention INC scores for personal generations, and these improvements maintained when assessed following a 2-week break. In addition, we documented growth in general language measures such as number of communication units, mean length of utterance, number of different words, and total number of words.

The purpose of this study was to explore the impact of oral narrative intervention delivered in a multi-tiered system of support format on proximal narrative retell outcomes, and more distal personal story generation and expository language outcomes of preschool and kindergarten students. Participants included 241 preschool and kindergarten students. Students were divided into 3 different groups (treatment, alternate treatment, and no-treatment control). The treatment group received Story Champs Tier 1 oral narrative language intervention from their classroom teacher twice a week for 15-20 minutes over 14 weeks. A sub-sample of students from the Story Champs group who did not meet a narrative retell criterion after 1 month of large group instruction were assigned to receive additional, Story Champs Tier 2 small group intervention. Tier 2 narrative intervention consisted of two 20-minute small group narrative intervention sessions each week for 14 weeks. The students assigned to the alternate treatment group participated in Tier 1 shared storybook reading intervention with their classroom teacher twice a week for 15-20 minutes over 14 weeks. Students in the no-treatment control group participated in classroom activities that were in place at the outset of the school year. Narrative retell and personal story language samples were elicited and scored using the CUBED Narrative Language Measures (NLM) subtest, and an expository language sample was elicited and scored using a researcher-generated protocol. Students in the Story Champs group had significantly higher posttest narrative retell scores with large effect sizes compared to the shared storybook and no-treatment control groups. Students in the Story Champs and shared storybook reading groups performed to a similar degree in their ability to generate a personal story at posttest. Expository retell posttest results were not significantly different between all of the different conditions. This study contributes to previous research suggesting that brief multi-tiered oral narrative language intervention can improve the receptive and expressive academic language of young children, as measured using narrative retelling. This study provides evidence that multi-tiered systems of support (MTSS) for language can be successfully delivered by teachers and speech-language pathologists working in the schools. It is also evident that both oral narrative language intervention and shared storybook interventions can improve personal story generations. However, the narrative-based interventions applied in this study did not appear to significantly impact expository language.
