the aim of this study was to carry out the semantic adaptation of Family Adaptability and Cohesion Evaluation Scale IV (faces IV) for Brazil. 45 participants were included, in addition to translators and evaluators. Three translations of the original version of the instrument were requested and compared with two Portuguese versions until a consensus version was reached, taking into account the meaning of the items in the original in English. It was assessed by three family therapists and ten lay judges, in terms of comprehensibility, and then retranslated in order to be assimilated directly to the original version. This gives the test version, which was applied to 35 adult participants, with an average age of 42,1 years. Obtiveramse higher average outlets at balanced sub-scales (cohesion = 25,0; flexibility = 25,5) when compared to unbalanced (disengaged = 17,6; embankment = 21,4; rigid = 22,1; chaotic = 16,9). The translation took into account the recommendations of different authors, paying attention to the consistency between the semantics of the items and the definition of the construct underlying the corresponding sub-scale. The resultant weekly mostrousis. Psychometric studies to check indicators of reliability and validity should be carried out.
