Assessing the responsiveness of the B razilian FIS to treatment for traumatic dental injury

Objective This study aimed to assess the responsiveness of the B razilian version of the F amily I mpact S cale (B‐ FIS ) to describe changes in the quality of life ( QoL ) after treatment for traumatic dental injury ( TDI ). Methods After applying the eligibility criteria, 156 patients from 2 to 14 years old, who were attending a dental trauma center, were selected over an 18‐month period. QoL was evaluated at two different appointments: A1 (after TDI ) and A2 (after TDI treatment). The B‐ FIS scores were calculated using the additive method. The responsiveness was analyzed by standardized response means ( SRM s). Results Mean B ‐ FIS scores were 12.1 (7.5 SD) and 2.7 (4.4 SD), while the median scores were 12.0 and 2.0, at A1 and A2 ( P  < 0.01), respectively. The B ‐ FIS responsiveness scores dropped 9.4 points after TDI treatment. The change was observed as a decrease in the impact after TDI treatment, demonstrating a positive reduction in its absolute number as well as an improvement in the family's QoL . The SRM achieved was as follows: 1.2 total scale, 1.1 parental emotions, 0.5 family conflicts, 0.9 parental/family activity, 0.1 financial burden. The B ‐ FIS scores indicated that TDI has significant impact on the family's QoL in A1 and still has impact in A2. The change was observed as a positive decrease in the impact after TDI treatment. Conclusions The responsiveness of the FIS ( B razilian version) in detecting the family's change in QoL after TDI treatment was confirmed by SRM .
