English language training

Training sessions on the CIDI instrument are temporarily suspended while we work toward updating the questionnaire and all related materials to meet new DSM-5 and ICD-11 diagnostic standards. This is a significant undertaking, affecting not only the questionnaire but also scoring algorithms, technical systems, and training materials. Please note that the updates are being made only to the computer-assisted interview (CAI) mode -- the Training and Reference Centre will no longer support the paper (PAPI) version of the questionnaire. We expect to hold the next training, using the new materials, in Fall 2015, and will post updates on this site as we make progress.

Training includes home-study training materials and 3 days of classroom training. In addition, participants will be expected to complete approximately 30 hours of home study.

Secondary analysis of WHO WMH-CIDI data:

Training is provided for people who want to use the WHO WMH-CIDI to carry out data collections. There is no relationship between training and access to any datasets that might have used the CIDI in the past. If researchers have an independent relationship with a research group that has previously carried out a CIDI survey and are being provided access to those data, that is a matter between the individuals involved.

The TRC does not provide overview training in the WHO WMH-CIDI for people who are only interested in secondary analysis. All training assumes that the trainee is being trained to conduct data collection using the WHO WMH-CIDI questionnaire. Secondary analysts will still find the training useful, but must recognize that they will be required to participate in the exercises that involve practice interviewing and other aspects of training that assume that data collection is the goal of training.
