The legacy 3di5 software

3di5 is the previous Microsoft Access-based version of the 3di clinical interview. This page preserves interface guidance and support information for trained users and organisations that still work with that version.

The 3di5 interface

The 3di5 organises the interview into numbered forms, tracks question status and provides two tree-based navigation tools. These screenshots and instructions describe only the legacy software.

Support for existing 3di5 users

Version-specific operating guidance, installation information and support contacts for 3di5 are kept together here.

3di5 installation and licensing

An installer for the 3di5 software comes as part of the training programme. Once a training date is agreed, installation is arranged on the laptop you bring to training. In NHS Trusts this may be completed by your IT department using supplied instructions; self-installation is also common in private practice.

The course fee includes:

  • Training course and materials
  • A 3di5 installer and single-user licence for the software version provided
  • One year of technical support, beginning with email and with telephone follow-up available

3di5 is licensed per user. Your entitlement stays with you if you move between employers, and trained users may work with the software in more than one context, for example in both NHS and private practice.

A new 3di6 workspace is coming

The new 3di6 brings patients, assessments, guided interviewing, review and reporting into a modern clinical workspace, carrying forward the established 3di method in place of the Microsoft Access-era interface. When an interview is complete, it generates a clinician report or a narrative summary letter for parents.

The guide at docs.ixdx.org describes 3di5, the previous Microsoft Access desktop software. It doesn’t cover the new 3di6 platform. It opens in a new tab.

The new 3di6 is coming

This page covers the legacy 3di5 software. The 3di6 is a major update to the 3di, the computerised interview for autism assessment: a cloud-based application for Windows and Mac, with guided interviewing and DSM-5 compatible analysis.

When an interview is complete, the 3di6 generates a detailed, structured clinician report that reads like a clinic letter, with an automated analysis, and a parent letter that explains the results to the family. It can save busy clinicians hours.
