Certainly, it can be said that the sibling relationship in emerging adulthood is a worthy topic to study seriously. Through this chapter, its importance was established, and the need to identify how this bond is assessed in Mexico was emphasized. Thus, sibling quality (and strategies for handling sibling conflict) was operationalized by performing relevant statistical procedures to determine its psychometric characteristics. Additionally, differences were explored among sisters, brothers, and siblings regarding attachment styles, similarity and complementarity, complicity, conversation topics, favoritism, conflict motives, jealousy, aggression, conflict management strategies, and sibling quality. Subsequently, this chapter proposed the ascertainment of a series of explanatory path models for each dyad (sisters, brothers, and siblings) and for each type of sibling quality (warm, respectful, constructive, pleasant, and loyal). These models included all the variables identified as predictors of sibling quality. Among the main results, valid, reliable, and culturally sensitive measures were obtained for the designed population. Primarily, differences were found between the dyads, justifying the proposal of explanatory path models. As for these models, fun and friendship were identified as the central complicity factor in explaining sibling quality, with various specific versions for each type of relationship. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
