Impact of Personal, Parental and Familial Characteristics on Sibling Relationship of Twins

The research on “Impact of personal, parental and familial characteristics on sibling relationship of twins” was conducted during 2016. The study consists 39 pairs of twins. The respondents selected for the study were belonging to 10-24 years age range from Hubli and Dharwad cities. The self structured schedule was used to gather personal information. Socio-economic status of their family was assessed by SES scale developed by Agarwal et al. Zygosity was assessed based on the physical similarities like height, weight, skin color, hair color etc. The sibling relationship was assessed by using Sibling Relationship Checklist (SRC) developed by Lord and Borthwicks. The data was analyzed by using fallowing statistical tools like frequency and percentage, Karl Pearson’s product moment correlation coefficient and Chi square. The results revealed that majority of monozygotic and dizygotic twins were had healthy sibling relationship (93.80 % and 76.10 % respectively). Age factor was negatively significantly correlated with sibling relationship of twins indicating that increase in age of the twins increase in the sibling relationship. Ordinal position is not much effecting because they born at same time. There was non-significant association was found, however there was highly significant relationship was observed between family size and sibling relationship of twins, indicating that small family helped to possess healthy sibling relationship among twins. Findings showed that there was no significant association and relation between parent’s education and occupation with sibling relationship. And there was no association and relation was observed between socio-economic status of the family and sibling relationship of twins. However genetic relatedness, same age individuals and sharing of common environment before and after birth, same home and school environment may add to healthy sibling relationship among twins.
