The purpose of the present study is to analyze the perception of the family therapists from Rio de Janeiro in relation to remarriage, and the theoretical and clinical approaches preferentially used to treat members of remarried families. The complexity and diversity present in the structure of remarried families, as well as the increase of this family form, indicate that the nuclear family model, determinant in the formulation of the initial approaches of family therapy, and to which remarried families are compared, is not an adequate parameter. The specialized literature points out that the different psychotherapeutic approaches should consider the essential differences between these two family forms. A field study based upon the review of the specialized literature was conducted. Ten family therapists from Rio de Janeiro were interviewed. The group was formed by six female and four male subjects. All of the subjects had more than fourteen years of clinical experience as family therapists, and initially followed a systemic orientation. Based on the theoretical framework and on the analysis of the subjects discourse, five categories were proposed. The final evaluation of the data demonstrates the significant influence of the nuclear family model in the formulations made by the subjects about family relations, as well as those made about the theoretical and clinical approaches used. Most of the subjects did not seem to consider the specific knowledge about remarried families relevant to his/her practice. It was possible to observe, through the words of most subjects, a distance between their clinical work and current researches on the matter.
