New HETUS-compatible online diary: ELiDDI (Extended Light Digital Diary Instrument)

CTUR has recently developed and run a HETUS-compatible version of its ‘Click and Drag Diary Instrument’ (CaDDI) designed to demonstrate how drop-down menus can expand the activity categories of the original design to compatibility with the full HETUS classification of activities list. In recognition of the visual similarity to the classic 'light' diary design, but with online-enabled extensions, we have renamed this new version the Extended Light Digital Diary Instrument (ELiDDI). For this version the basic 7-field design of the original CaDDI was retained, but the main and secondary lists of activity were expanded in drop-down menus to include over 100 activities, fully compatible with the 2018 HETUS Guidelines (minor changes were also made to the location field and transportation mode coding to ensure compatibility). 

A presentation on 'Time use diary design for our times - an overview, presenting a digital diary instrument' (pdf) was given at the recent International Association of Time Use Research annual conference, which outlines the rationale, history and development of the ELiDDI design. 

A demonstration file showing the process of completion for both a horizontal (computer screen) or vertical (smartphone) functionality is available below.

While previous CaDDI datasets have been collected using quota-representative market research panel respondents, the new ELiDDI version has recently been successfully run using a UK nationally-representative sample, provided by NatCen Social Research.  The resulting data set is currently in preparation for deposit in the UK Data Archive. 

There are two potential ways for researchers to access the CTUR online diary instruments, listed below.  Please contact CTUR if you are interested in either of these options:

  • negotiate with our design partner to run inexpensive, real-time surveys using these tools, either sampling from their large, international, market research panel of respondents (from which socio-demographic quotas may be selected), or, alternatively, providing researcher’s own samples of respondents (more expensive as it requires more back-office organisation).  
  • we are also happy to allow free non-commercial reproduction, so researchers may reproduce the tool and associated back-office functions, storing the collected data onto their own servers.
