Abstract
The overall goal of this thesis is to explore the contribution of genetic factors, environmental factors, and the role of parenting on attachment security in adolescence. The thesis comprises three studies based on data from two samples of adolescents (age:15 years ±14 months) collected from the Twins Early Development Study (TEDS), a large longitudinal cohort of same-sex twins born in the UK between 1994 and 1996. The first study was conducted on 599 participants (341 females) and aimed to examine the associations between self-report and interview-based attachment measures by adopting two of the most widely used instruments in the field: The Inventory of Parent and Peer Attachment (IPPA) and the Child Attachment Interview (CAI). This study also aimed to establish whether a dimensional approach (i.e. continuous measures of attachment) or a categorical approach (i.e. attachment classifications) to the IPPA affords a better prediction of attachment security as assessed through the CAI. The second study was conducted on 592 twin pairs (321 females) to investigate the genetic and environmental influences on adolescent attachment security in relation to parents and peers assessed through the IPPA. This study fills a gap in the existing literature by examining the role of genes and environment on adolescent attachment assessed through a self-report measure, and examining the genetic and environmental influences on the covariation between peer and parent attachment. The third and final study, conducted on the same sample as the second study, aimed to firstly test the relative role of genetic and environmental influences on the quality of parenting and secondly examine whether common genetic factors or common environmental factors underlie the covariation between parenting and adolescent attachment security assessed through both the CAI and the IPPA. Results showed that attachment in adolescence and its correlation to parenting are significantly determined by genes, independently of the assessment measures adopted.
