This paper reports a preliminary evaluation of the [Talkable] 10-week language learning programme. This training programme aims to help caregivers provide a rich language learning environment in a child's first 3 years of life through the provision of evidence-based information and practical strategies to promote language development delivered primarily via mobile application. Participants in the study completed pre- and post-programme surveys on a range of questions relating to their knowledge and confidence in assisting their child's language learning. Results indicated significant improvements in participant's self-reported levels of knowledge about early language development and ways to assist their child's language learning, while level of concern about their child's language development remained fairly constant. These findings provide preliminary support for the use of [Talkable] in primary prevention, and direction for future development of the programme. Findings also add to the currently limited evidence-base for providing early language primary prevention programmes via mobile application.
