We examined profiles of sibling relationship qualities in 246
Mexican-origin families living in the United States using latent profile
analyses. Three profiles were identified: Positive,
Negative and Affect-Intense. Links between
profiles and youths’ familism values and adjustment were assessed using
longitudinal data. Siblings in the Positive profile reported
the highest familism values, followed by siblings in the
Affect-Intense profile and, finally, siblings in the
Negative profile. Older siblings in the
Positive and Affect-Intense profiles
reported fewer depressive symptoms than siblings in the
Negative profile. Further, in the Positive
and Negative profiles, older siblings reported less involvement
in risky behaviors than younger siblings. In the Negative
profile, younger siblings reported greater sexual risk behaviors in late
adolescence than older siblings; siblings in opposite-sex dyads, as compared to
same-sex dyads, engaged in riskier sexual behaviors. Our findings highlight
sibling relationship quality as promotive and risky, depending on sibling
characteristics and adjustment outcomes.
