Summary
Introduction
We provide an overview of two studies examining the reliability of the CORE II measure in the hands of clinicians (with a comparison of ratings made by relatives and by psychiatrists having been reported in Chapter 6). The first (MDU) study was undertaken by the consultant psychiatrists involved in the development of the core measure. There is a risk to any such endeavour – in that the consultants, as experienced clinicians, may rate on the basis of clinical intuition (i.e., they might observe a patient, “smell” melancholia, and “rate up” on the core system – or conversely “rate down” when assessing non-melancholic depression), bringing about invalid agreement between core ratings. The second (NIMH) study, involving non-MDU staff, provided an opportunity to overcome any “intellectual incest” or related bias, in addition to allowing the reliability of the core system to be tested for non-psychiatrists and from video (rather than live) interviews.
Methods
The MDU Study. Shortly after designing the CORE II schedule, we commenced an inter-rater reliability study. The procedure involved one of five consultant psychiatrists (HB, PB, IH, PM and KW) interviewing a depressed patient for at least 20 minutes, with two or more of the other consultants observing the interview. At completion, each consultant made an independent rating of all core signs, ratings were reviewed and disagreements were discussed in detail.
