Performance del GHQ-30 in un setting ambulatoriale psichiatrico: validazione con casi-controlli appaiati. / Performance of the GHQ-30 in a psychiatric ambulatory setting: A matched pairs case-control validity study

Studied the validity of an instrument for classifying psychiatric patients, using a matched case-control study design. Human subjects: 30 male and female Italian adults (aged 18 yrs and older) (neuroticism). 30 male and female Italian adults (aged 18 yrs and older) (population controls). All Ss completed the General Health Questionnaire-30 (GHQ-30), and differences between cases and controls were evaluated statistically and compared to results from other studies on Italian population groups. Sensitivity, specificity, and positive predictive value were determined according to Ss' age, sex, and socioeconomic status (SES). The gravity of symptoms was rated according to D. Goldberg and B. Blackwell's Psychiatric Overall Severity Rating Scale (1970). Control patients were evaluated according to the Clinical Interview Schedule by Goldberg et al (1970).
