RESUMEN
@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> This study assessed the reliability and validity of a Filipino version of the Cardiff Acne Disability Index.<br /><strong>METHODS:</strong> In Phase 1, the Cardiff Acne Disability Index (CADI) was translated into Filipino as the Cardiff Indeks ng Kapansanan ng may Tigyawat (CIKT) following international guidelines on translation and cultural adaptation, and passed a cognitive debriefing test (a form of face validity testing). In Phase 2, the CIKT was administered to 400 public high school students (11-18 years old). Cronbach's ? was used to measure reliability while construct validity was determined by comparing 1) the CIKT scores of adolescents with acne and those without acne and 2) the CIKT scores with the scores of the Taluntunan ng Kalidad ng Buhay na Hinggil sa Dermatolohiya (TKBD), which is a validated Filipino version of the Dermatology Life Quality Index.<br /><strong>RESULTS:</strong> Cronbach's ? showed an adequate internal consistency of 0.7. The linear regression coefficient for those with and without acne was 0.98 (CI 0.59, 1.37) (p = 0.00) while the Spearman correlation showed a positive correlation between the CIKT and the TKBD (0.58, p=0.00), both indicating validity.<br /><strong>CONCLUSION:</strong> The CIKT is a reliable and valid Filipino translation of the CADI.</p>
