All interviewers receive structured training on the use of the DI-PAD. The DI-PAD training is done in person by master raters. A critical element is side-by-side interviews with psychiatric patients by both the trainer and the trainee. Ongoing support is provided to all sites. The lead trainer visits each site yearly. During the site visits, the trainer observes in-vivo interviews and rates alongside the interviewer. Additionally, inter-rater and inter-site reliability tests are conducted yearly.
