Objective: To explore attachment narratives in children diagnosed with reactive attachment disorder (RAD). Method: We compared attachment narratives, as measured by the Manchester Child Attachment Story Task, in a group of 33 children with a diagnosis of RAD and 37 comparison children. Results: The relative risk (RR) for children with RAD having an insecure attachment pattern was 2.4 (1.4-4.2) but 30% were rated as securely attached. Within the RAD group, children with a clear history of maltreatment were more likely to be Insecure-Disorganised than children without a clear history of maltreatment. Conclusions: Reactive attachment disorder is not the same as attachment insecurity, and questions remain about how attachment research informs clinical research on attachment disorders.

In a recent article published in Criminology, Burt and Simons (2014) empirical investigations, 2) the violation of assumptions in twin models does not invalidate their results, and 3) Burt and Simons created a distorted and highly misleading portrait of behavioral genetics and those who use quantitative genetic approaches."The flaws of twin studies are not fatal, but rather seem no worse (and may be better) than the flaws of the typical causal study that relies on observational data." (Felson, 2012: ii) Behavioral genetic research has existed for more than 100 years (Maxson, 2007). Since its inception, it has been a lightning rod of criticism, especially by scholars who are inalterably opposed to linking biology with behavior. Over this time, numerous critics (e.g.,

Despite the fact that low self-control and exposure to delinquent peers are two of the most robust and consistent predictors of crime, delinquency, and antisocial behavior, much remains unknown about what causes self-control to develop and what causes youths to befriend antisocial peers. This study estimated the relative effects of environmental and genetic factors on levels of self-control and contact with delinquent peers in a sample of twins from the National Longitudinal Study of Adolescent Health (Add Health). DeFries-Fulker analysis of the Add Health data revealed that both self-control and contact with drug-using friends were influenced by genetic factors and the nonshared environment, whereas the shared environment exhibited relatively small and inconsistent effects. Implications for self-control theory and social learning theory are discussed.

Objectives: To explore the link between low self-control during adolescence and health problems in early adulthood. Methods: Using data from the National Longitudinal Study of Adolescent Health, we examined the relationship between varying levels of self-control and the likelihood of being diagnosed with a variety of physical and brainbased health conditions. Results: Results from logistic regression analyses indicated that subjects with lower levels of self-control had significantly higher odds of being diagnosed with 9 of the 10 health outcomes. Conclusions: Targeting the development of selfcontrol in childhood and adolescence may be valuable in preventing future health problems.
