title: Initial assessment of responsiveness of the P-CPQ (Brazilian Version) to describe the changes in quality of life after treatment for traumatic dental injury.
abstract: This study aimed to assess the responsiveness of the Brazilian version of the Parental-Caregiver Perception Questionnaire (B-P-CPQ) to describe changes in quality of life (QoL) after treatment for traumatic dental injury (TDI). After eligibility criteria were applied, 42 of 255 patients who went to a dental trauma center for TDI treatment were included. QoL was evaluated in two different appointments: A1 (after TDI) and A2 (after TDI treatment). The B-P-CPQ scores were calculated using the additive method. Psychometric properties like internal consistency (Cronbach's Alpha), test-retest reliability, intraclass correlation coefficient (ICC), and construct validity (Spearman's correlations) were assessed, and, mainly, the responsiveness was analyzed by standardized response means (SRM). Mean B-P-CPQ scores were 30.05 (1.74 SD) and 2.67 (4.05 SD), while the median scores were 17.39 and 2.00 (P < 0.01), respectively in A1 and A2. Cronbach's Alpha was 0.87 in A1 and 0.66 in A2. ICC was 0.90. B-P-CPQ scores were correlated with overall well-being (P < 0.01; rho: 0.71). The B-P-CPQ responsiveness scores declined 27.38 points, and a perfect SRM of 1.76 was achieved. The B-P-CPQ scores indicated changes in QoL following TDI. The change was observed as an impact decrease after TDI treatment, demonstrating positive reduction and improvement on QoL. The responsiveness of the P-CPQ (Brazilian version) in detecting change on QoL after TDI treatment was confirmed by SRM assessment. The findings represent an evidence of the importance of professional care and treatment of TDI.
