Psychiatric diagnoses

Description

N = 30 patients were given one of k = 5 diagnoses by some n = 6 psychiatrists out of 43 psychiatrists in total. The diagnoses are

1. Depression

2. PD (=Personality Disorder)

3. Schizophrenia

4. Neurosis

5. Other

Usage

Format

diagnoses

A matrix with 30 rows and 6 columns:

rater1

1st rating of some six raters

rater2

2nd rating of some six raters

rater3

3rd rating of some six raters

rater4

4th rating of some six raters

rater5

5th rating of some six raters

rater6

6th rating of some six raters

Details

A total of 43 psychiatrists provided diagnoses. In the actual study (Sandifer, Hordern, Timbury, & Green, 1968), between 6 and 10 psychiatrists from the pool of 43 were unsystematically selected to diagnose a subject. Fleiss randomly selected six diagnoses per subject to bring the number of assignments per patient down to a constant of six.

As there is not a fixed set of six raters the ratings from the same column are not related to each other. Therefore, compared to the dataset with the same name in package irr, we applied a permutation of the six ratings.
