SEMI-STRUCTURED INTERVIEW Before beginning the music therapy treatment each participant will be asked set questions about it and to score how much they think it will improve their paretic arm use in activities of daily living. At the end of treatment participants will be asked the same questions. The chief investigator will write down responses during the interview for later thematic analysis. Interviews will not be recorded. Questions have been used that are as open as possible so as to give participants the opportunity to express their preconceptions and thoughts. Each question may lead to further questions, for example question 1 may prompt a response 'I think it will help me" to which the chief investigator may respond "how might it help you?" The purpose of the semi-structured interview is to gather qualitative data specifically regarding how participants experienced the treatment. The pre and post questions are set out below.
