Content and correlates of sisters’ messages about dating and sexuality

Siblings are influential on one another’s romantic relationships and sexual behaviors, and examining mechanisms of this influence is important. Using a sample of 62 sister dyads, we examined the content of sisters’ messages about dating and sexuality and correlates of these messages. Sisters shared messages with one another about dating logistics, dating partners, sex, and the importance of self. Using actor–partner interdependence models, we examined how both dyad members’ romantic relationship status and sexual experiences, intentions, and attitudes were associated with sisters’ messages. We found sisters’ experiences—especially older sisters’ experiences—were associated with the content of messages. Consistent with symbolic interactionism, the findings point to the importance of examining sibling communication about dating and sexuality as an important socialization mechanism through which sisters may influence one another’s romantic relationships and sexuality development
