Change in maternal report of sibling negativity was investigated in 313 sibling dyads from 171 families taking part in a longitudinal, general population survey in the United Kingdom. The inclusion of multiple dyads per family allowed for the emergence of 3 novel elements for sibling research: an examination of within-family similarity on sibling relationship quality, modeling within-family sim...

This study examined older adolescents' perceptions of the following sibling relationship characteristics: advice about life plans and personal problems, satisfaction with support, and sibling influence on interests and goals. Little is known about late adolescent sibling relationships and siblings' role in the identity formation process. Differences between firstand secondborns, males and femal...

This paper presents new estimates of sibling correlations in health and socioeconomic outcomes over the life course in the U.S. Sibling correlations provide an omnibus measure of the importance of all family and community influences. I find that sibling correlations in a range of health and socioeconomic outcomes start quite high at birth and remain high over the life course. The sibling correl...

Sibling relationship and personality characteristics of 87 pre-school sibling dyads were measured twice one year apart. Using the Inventory of Child Individual Differences (Halverson et al., 2003), mothers and fathers rated their children’s personality traits. Parent-perceived warmth, agonism, and rivalry/competition in sibling relationship were assessed by Parental Expectations and Perceptions...

The present study examined delinquency concordance and the moderating effects of younger sibling perceptions of older sibling popularity in a sample of 587 adolescent sibling pairs. Using a social learning framework, and taking dyad composition into account, perceptions of popularity were hypothesized to strengthen siblings' concordance for delinquency. Older sibling delinquency significantly p...

the most important factor in donor-recipient matching for hematopoietic stem cell transplantation is their hla typing. for many patients, we can not find a full-matched donor. in high risk patients, one locus  mismatched related donors are suitable alternatives. (1, 2) since the matching of patients and their siblings usually is based on low resolution hla typing, the matching of one locus mism...
