Abstract
Several recent studies suggest that individuals exhibit better social skills if raised with siblings. This pattern has been demonstrated among kindergartners and adults, but oddly is inconsistent among adolescents. Analyzing 1662 youths from the National Longitudinal Study of Adolescent Health (Add Health), we replicate what others have found—no association between number of siblings and number of friendship nominations received by peers. But we expand on previous research by merging structuralist approaches (focusing primarily on number of siblings) and interactional (emphasizing relationship quality) traditions. We find clear evidence that positive sibling relationships are associated with more peer nominations. This study contributes to growing evidence that sibling relationships shape individuals’ ability to form and maintain relationships with others outside of the family. It also explains why the relationship between number of siblings and social outcomes is not evident during the adolescent years—a period when interactional components of sibship may outweigh structural ones.

Notes
We are unaware of a more recent nationally representative dataset that has indicators of sibling relationship quality and peer nominations.
Before restricting our analyses to the subsample of adolescents with siblings, we first tested the broader sample to note whether individuals with no siblings received fewer peer nominations than those with any siblings. Like Bobbit-Zeher and Downey (2013), we found no relationship between sibship size and peer nominations.
We also considered the effect of the number of siblings of the same sex as the respondent and the effect of the number of siblings of the opposite sex from the respondent. In order to do this, we tested interactions between respondent’s sex and the number of siblings of the same sex as the respondent, as well as interactions between respondent’s sex and the number of siblings of the opposite sex from the respondent. None of these interactions were statistically significant.
The model fit was assessed using the following fit indices. According to Chi-square goodness of fit test, the chi-square with five degrees of freedom is significant (χ 2(5) = 30.45, p < .001). The insignificant p value for chi-square test indicates that the model fits the data well. However, with large sample sizes (i.e., 400 or more), the chi-square is almost always statistically significant. If the study uses a large sample size like ours, the researcher then examines other fit indices to determine the fit of the model, such as CFI, TLI, and RMSEA (Kenny et al. 2006). On the other hand, for TLI and CFI, values greater than 0.90 are indicative of a good model fit (Hoyle 1995).Some additional fit indices indicate that the model fits the data well; the Comparative Fit Index (CFI) = 0.96, the Tucker-Lewis Index (TLI) = 0.95, and the Root Mean Square Error of Approximation (RMSEA) = 0.04, With regard to factor loadings, the standardized coefficients of the five items ranged between 0.58 and 0.95 which is above the acceptance level of 0.30 (Carvalho and Chambel 2016).
We also controlled for the length of time in school by including the current grade at the time of wave 1 in the analyses, but this control variable was not found significant in predicting friendship nominations. Therefore, it was not included in our current models.
