Prospective associations among parent-adolescent acceptance and familism values in early and middle adolescence and sibling intimacy in late adolescence and young adulthood were assessed in 246 Mexican-origin families. Older sibling gender and sibling gender constellation were investigated as moderators of these associations. Sibling intimacy was stable over time and younger siblings with older sisters reported higher levels of sibling intimacy than those with older brothers. As predicted, stronger familism values were associated with greater sibling intimacy, but this link was evident only for older sisters and for girl-girl dyads. The links from mother- and father-acceptance to sibling intimacy also depended on the gender constellation of the sibling dyad: Higher levels of maternal warmth were associated with greater sibling intimacy for older sisters and girl-girl sibling pairs but higher levels of paternal warmth were linked to greater sibling intimacy only for older siblings in mixed-gender sibling dyads. Findings are consistent with prior research on the role of gender in family relationships but extend this work to encompass the effects of both parents' and siblings' gender, as well as the role of sociocultural values in parents' socialization influences.
