This dataset contains 17 anonymised interview transcripts with Approved Mental Health Professionals (AMHPs) about their experiences working with interpreters during Mental Health Act assessments. The semi-structured interviews provide rich qualitative insights into the challenges and best practices of interpreter-mediated mental health evaluations, including communication dynamics, procedural barriers, and recommendations for service improvement. All transcripts have been carefully de-identified to remove personal and organisational identifiers while preserving the substantive content and are presented as PDF documents suitable for qualitative analysis.
