RESUMO
This systematic review addresses the gap in the literature regarding sibling relationship quality among Latinx families, a topic that has not been comprehensively examined to date. This study aimed to synthesize current research on sibling relationship quality in Latinx families, focusing on the influence of cultural factors, identifying key variables associated with sibling relationship quality, and evaluating the methodological approaches used. This paper is a systematic review based on a recently published evidence and gap map (EGM) that identified and visually presented all published studies investigating sibling relationship quality. Additional inclusion criteria were applied to select articles that specifically examined sibling relationship quality in the United States samples with at least 50% Latinx participants. The review included 12 articles representing 6 distinct studies, revealing significant findings on the roles of familism, simpatía, and gender in shaping sibling dynamics. Results indicated that cultural values such as familism and simpatía positively influence sibling intimacy and warmth, while gender dynamics further moderate these relationships. Methodologically, the articles employed longitudinal and cross-sectional designs, utilizing various quantitative measures. The findings underscore the importance of culturally sensitive approaches in studying sibling relationships and highlight the need for further research to explore these dynamics in diverse Latinx subgroups.
