To transculturally adapt and validate the Karitane Parenting Confidence Scale (KPCS) to the Brazilian Portuguese language and culture and verify the combination of the results with the maternal sociodemographic characteristics. This is a validation and transcultural adaptation nestled in a longitudinal and observational study in Porto Alegre, RS, Brazil, assessing mother-infant pairs from different gestational environments. The original authors authorized the translation into Brazilian Portuguese, unified version creation, back-translation, analysis by specialists, final version implementation, and acceptance. Cronbach's alpha analysis was performed. The Kruskal-Wallis test with post-hoc Dunn's test was used to compare the study groups. Socioeconomic and demographic characteristics, obtained through a questionnaire in the first 24-48h of the newborns' life, were associated with maternal results by using the Brazilian version of the scale, using Spearman's and Mann-Whitney's correlations. The sample consisted of 251 postpartum women, with the questionnaire being applied at 15 days postpartum. The median score of the mothers' confidence was 40.00 (37.00-43.00). The protocol obtained a Cronbach's alpha of 0.717. There were significant weak positive correlations between maternal confidence and age (p=0.013, r=0.157) and between maternal confidence and schooling (p=0.048, r=0.125). Additionally, a significant association was observed between maternal confidence and parity (p=0.030). The transcultural adaptation and validation of the KPCS into Brazilian Portuguese language and culture showed good reliability for this sample. The results of its use demonstrated that maternal confidence was associated with schooling, age and parity.
