Comportamentos extra-diádicos nas relações de namoro: Diferenças de sexo na prevalência e correlatos

Alexandra Martins, Marco Pereira, Maria Cristina Canavarro


O presente estudo teve como objetivo avaliar as diferenças de sexo nas taxas de prevalência e nos correlatos dos comportamentos extra-diádicos (CED) of line e online, durante o namoro. A amostra foi constituída por 494 participantes (156 homens e 338 mulheres) com uma idade média de 23.38 anos (DP=3.41). O protocolo de avaliação incluíu os seguintes instrumentos de auto-resposta: Inventário de Comportamentos Extra-Diádicos e Medida Global da Satisfação Relacional e Medida Global da Satisfação Sexual. Cerca de 63.5% dos homens e 56.5% das mulheres reportou já se ter envolvido em CED of line e 46.2% dos homens e 39.3% das mulheres já se envolveu em CED online, sendo que esta diferença não foi significativa. Para ambos os sexos, já ter sido infiel a um parceiro e menor satisfação relacional foram preditores importantes do envolvimento em CED of line e online. Para os homens, pertencer à religião Católica e história prévia de infidelidade do pai foram preditores significativos dos CED online. Entre as mulheres, o número de parceiros sexuais nos últimos dois anos associou-se significativamente ao envolvimento extra-diádico of line. Embora homens e mulheres cada vez se aproximem mais no que respeita às taxas de prevalência, os correlatos do envolvimento em CED diferem em função do sexo. Sugestões para investigação futura são apresentadas à luz destes resultados.
