BACKGROUND: The 4-item index of the 19-item Acne-Quality of Life (Acne-QoL) has been validated in English (AcneQ4). French translation and linguistic validation of the Acne-QoL have recently been completed (Acne-QoLfr). PURPOSE: This study sought to evaluate reliability and responsivity of the French version of the AcneQ4 (AcneQ4fr). METHODS: Calculation of intraclass correlation coefficients (ICC) and regression modeling was performed to evaluate reliability (comparing Day 0 to Day 2-3 responses) and responsivity (comparing Day 0 to Day 60+ responses). RESULTS: Thirty-four native French-speaking acne subjects in Quebec, Canada (n = 20) and France (n = 14) completed the Acne-QoLfr on 3 occasions over 3 months (Day 0, Day 2-3, and Day 60+). Of 14 completed responses for Day 0 and Day 2-3, ICC for AcneQ4fr was 0.73 (with 95 % confidence interval (0.348, 0.905) and P value 0.001), and mean score difference was 0.85 (range of possible scores for AcneQ4fr: 0-24; P = 0.41). Of 19 completed responses for Day 0 and Day 60+, ICC for Acne-Q4fr was 0.45 (with 95 % confidence interval (0.046, 0.728) and P value 0.015) and mean score difference was 4.14 (P = 0.001). CONCLUSIONS: The abbreviated AcneQ4fr is somewhat reflective of the entire Acne-QoLfr and by its brevity may facilitate psychometric evaluation of francophone acne patients in routine practice.
