(1985) in another general practice study in Italy.īellantuono C, Fiorio R, Williams P, Cortina P (1987) Psychiatric morbidity in an Italian general practice. Using the Psy-OSR ≥2 or the CIS Total Weighted Score ≥13 as indicators, the prevalence of “true” cases in this sample was 35.5% and 38.8% respectively, a rate lower than that reported by Fontanesi et al.
A comparison of the performance of the GHQ-30, GHQ-12 and C-GHQ (Goodchild and Duncan-Jones method of scoring), obtained in the usual way, as well as using ROC analysis showed that the C-GHQ gave the best overall results, but the difference was not significant. The corresponding figures of sensitivity and specificity for a GHQ cut off 4/5 were 89% and 65%. According to this cutting score, 47.8% of patients were high scorers. Taking the Overall Severity Rating made by the psychiatrist (Psy-OSR) at the end of the CIS as the criterion, the best CIS threshold in discriminating between “cases” and “non cases” was 12/13, while the GHQ cut off point of 5/6 gave the best results in terms of balance between sensitivity (81%) and specificity (71%). The Italian versions of both the GHQ and the CIS were confirmed as feasible instruments for general practice studies in Italy. Ninety consecutive patients aged 14 and above attending a general practice in Verona completed the 30-item General Health Questionnaire (GHQ), were assessed by the general practitioner for the presence of psychiatric disturbances on a 5 point scale, and interviewed by a psychiatrist using the Clinical Interview Schedule (CIS).
