The interview remains the most common method of data gathering in qualitative research, employed in various forms by every main theoretical and methodological approach within qualitative applied psychology. As such, it is impossible to provide a comprehensive account of the method within one relatively short chapter. Rather, my aim is to give an introduction to the variety of forms of qualitative research interview (and the assumptions that underly their use), before providing practical guidance on how to design and carry out a study using this method. The recommended texts detailed at the end should help readers deepen their knowledge of those aspects of the method of most relevance to their own work.
