To test the reliability and robustness of the CPRS in use by different disciplines we obtained 49 pairs of ratings on depressed patients in England and Sweden during treatment. Each rater pair consisted of a psychiatrist trained as a rater plus either a psychologist, a general practitioner, or a nurse, who had not been trained as a rater. The 17 most commonly rated items in depressive illness showed good inter-rater reliability for all groups and demonstrated the robustness of the scale even in training sessions. The implications of this for future interdisciplinary research are discussed along with suggestions for the use of the CPRS for teaching purposes.
54 English and 52 Swedish patients suffering from primary depressive illness were rated on the full 65 item CPRS scale to examine cross cultural differences. The correlation of the frequencies of items scored in the different patient samples was highly significant (r = 0.88). Of the most commonly scored items (occurring in more than 70% of any of the patient groups) 17 were common to both samples. The three items not in common for the two centres are compared and discussed. The inter rater reliabilities of the Swedish and English teams are compared alongside the inter rater reliabilities of a Swedish rater and an English rater on English patients and are generally good. The remarkable similarity of the psychopathology of primary depressive illness in both cultures and some of the implications are discussed.
