Abstract:
This pre-registered randomized clinical trial examined the efficacy of a prevention program on parenting of siblings and sibling relationships among Latinxs. Participants were 272 sibling dyads (82.9% Mexican) with 5th graders (Mage = 10.63; SD = 0.38; 51.8% female), their younger siblings in 1st to 4th grades (Mage = 8.18; SD = 1.06; 54.8% female), and their caregivers. Families were randomized to Siblings Are Special (SIBS; n = 161) or an alternative academic skills program (n = 111). Data were collected pre- and post-program (2018-2022). Significant effects were detected for sibling-focused parenting in the expected direction for authoritarian control and non-intervention in sibling conflicts, but there were no effects for sibling relationship quality. Implications of COVID-19 and future directions are discussed.
