Establishing a clinical high-risk program in Tunisia, North Africa: A pilot study in early detection and identification.

backgroundEarly identification and prevention research has provided huge advances in our understanding of early screening and identification of young people at clinical high-risk (CHR). Most of these procedures were developed in high-income countries, yet middle-income countries in North Africa such as Tunisia can benefit from these empirically-based assessment approaches.

methodsUsing established procedures, nine Tunisian psychiatric raters were trained on structured assessments: the CAARMS, BPRS, and SCID to high standards of interrater reliability. These raters developed a clinical high-risk program (CHiRP) in Tunisia and recruited 10 patients who were exhibiting possible signs of CHR. These patients were evaluated to determine if they met criteria for a CHR group, such as Attenuated Psychosis.

resultsTrained raters met the following interrater reliability criteria for the CAARMS and BPRS (ICC = .80 or greater) and the SCID (Kappa = .75 or greater). Of 10 pilot patients, six were classified as CHR and belonging to the Attenuated Psychosis Group. One of the six patients converted to psychosis 3 months after study entry for a conversion rate of 17% which is comparable with currently published rates globally. DISCUSSION: The first CHR program has been established in Tunisia, a middle-income country using methods developed in high income countries. Efforts aimed at assembling a group of prevention-oriented psychiatrists, obtaining administrative support, and training raters to high levels of interrater reliability were successful. The feasibility was demonstrated for screening, assessing, treating, and following-up of 10 CHR patients suggesting that conversion rates are comparable to those of Western and European countries.
