Spanish adaptation and validation of the Partner Behaviours ss Social Context (PBSC) self-report

Basic psychological needs theory (Deci & Ryan, 2000) is an interesting approach to understand the dynamics of romantic relations. Having valid and reliable instruments will allow assessment of the romantic relationship from this perspective. The aim of this study is to present the development of a Spanish version of the Partner Behaviours as Social Context (PBSC, Ducat & Zimmer-Gembeck, 2010) scale. Through two studies, the factor structure originally proposed is analyzed, determining scale reliability and validity. The results confirm the six-dimension structure, although with some differences. It can be concluded that the proposed scale is an especially interesting instrument for the study of relationships in Spanish-speaking youth.
