This study was conducted as a twofold investigation. Firstly, it focused on refusal strategies and modification tools employed by a group of Turkish EFL learners. Secondly, it aimed to compare the content of data collected via two different data collection tools popular in interlanguage pragmatics research: Discourse Completion Task and open role plays. As the target speech act, refusals have been the focus of the investigation. The results showed that the participants could use a range of refusal strategies appropriately and the data collected via DCT and role plays were significantly compatible in terms of variety of strategies employed by the participants.
