Background A self-administered Early Inflammatory Arthritis (EIA) tool has been developed.1-3

Objectives The purpose of this study is to cross-culturally adapt the developed EIA detection tool for the Canadian Francophone population and to determine its psychometric and discriminative properties. The external validity of a scoring algorithm previously developed in an English-speaking population was tested.

Methods Three groups were recruited from outpatient clinics at two tertiary care hospitals: 92 EIA; 106 established IA; 94 non-IA. The current study was completed in four phases. Phase I: Translation and adaptation of the English tool into Canadian Francophone culture was conducted independently by two sets of translators. Phase II: A committee adjudicated the translated and adapted items to derive a single cross-culturally adapted tool. Phase III: A pilot validation study of the tool was conducted on a Canadian Francophone sample of 80 participants. Comprehensibility, internal consistency and test-retest reliability of the tool were determined. Phase IV: A full-scale validation study of 292 Canadian Francophone participants was conducted to determine the discriminative properties of the tool.

Results A translated and cross-culturally adapted to Canadian French version of the EIA Detection Tool, with 100% committee agreement was produced. Comprehensibility approached unity for all tool items. The internal consistency Kuder-Richardson-20 was 0.96 (p<0.0001). The mean test-retest reliability kappa (standard error, SE) was 0.67 (0.03). The intraclass correlation coefficient (ICC) for summed ‘yes’ responses between test and retest phases was 0.77 (p<0.0001) and for algorithm scores was 0.86 (p<0.0001). The scoring algorithm receiver operating characteristic plot area under the curve (SE) was 0.818 (0.002).

Conclusions The tool has favorable measurement and discriminative properties. A cross-culturally adapted and validated EIA Detection Tool for Canadian Francophones may improve appropriate care for this population.
