Members of the ARCH group have been collecting and analysing video recordings of naturally occurring interactions between health practitioners and patients since 2004. This data set, together with a custom- designed information management system comprises the ARCH Corpus, a searchable digitised collection of health care interactions and related data for use in interaction analysis.

The ARCH Corpus of Health Interactions is the first data set of its kind in New Zealand:

  •  A “living data bank” of digitally recorded New Zealand health interactions and associated information collected progressively since 2004 (not a formally structured corpus). Data are permanently archived (with consent of participants) for future use by authorised researchers and educators
  • A comprehensive data management system has been developed (including a searchable ACCESS database with links to audio & video recordings, logs and transcripts, medical notes and field notes, and other associated documents)
  • The primary data in the ARCH Corpus includes:
    1. video/audio recordings of consultations, other patient-health professional interactions, and professional interactions and meetings
    2. participant interviews and focus groups
    3. ethnographic and demographic data
    4. medical records & other documents

Development of the ARCH Corpus:

Data collection began in 2004. Data from a number of studies have been added over the years including interviews with patients / service users and health providers. Collection continues.
