BACKGROUND Families of children with attention-deficit/hyperactivity disorder (ADHD) report higher rates of conflict within the family and more negative parent-child relationships. This study aimed to test whether negative parent-child relationships have a risk effect on ADHD symptoms using two complementary designs. METHOD The first sample included 886(More)
AIMS To examine the genetic and environmental contributions to the initiation of use and progression to more serious use of alcohol, cigarettes and marijuana during adolescence, and to examine the relationship between initiation and progression of substance use. DESIGN The study used a twin-based design and a new theoretical model, the(More)
Evidence both from psychological research and clinical intervention studies suggests that there are bidirectional influences between overt child behavior problems and parent-child relations. Very little research however, has considered the pattern of relations that exists between Attention Deficit Hyperactivity Disorder (ADHD) and the parent-child(More)
AIMS Genetically influenced aspects of adolescent behaviour can play a role in alcohol use and peer affiliation. We explored the correlations between friends' alcohol use and adolescent own use with a genetically sensitive design. DESIGN Genetic and environmental factors were estimated on adolescent reports of their friends' alcohol use and their own use(More)
OBJECTIVE To assess the value of maternal and self-ratings of adolescent depression by investigating the extent to which these reports predicted a range of mental health and functional outcomes 4 years later. The potential influence of mother's own depressed mood on her ratings of adolescent depression and suicidal ideation on adolescent outcome was also(More)
The present study used a prospective, longitudinal design to investigate genetic and environmental influences on the association between earlier conduct problems and the initiation and progression of marijuana use during adolescence. Parent- and teacher-reported conduct problems assessed at Time 1 (1996) and self-reported marijuana use assessed at Time 2(More)
OBJECTIVE The current study aimed to identify the barriers to participation among high-risk individuals in the UK Lung Cancer Screening (UKLS) pilot trial. SETTING The UKLS pilot trial is a randomised controlled trial of low-dose CT (LDCT) screening that has recruited high-risk people using a population approach in the Cambridge and Liverpool areas.

BACKGROUND Primary endocrine therapy (PET) is a recognised alternative to surgery followed by endocrine therapy for a subset of older, frailer women with breast cancer. Choice of treatment is preference-sensitive and may require decision support. Older patients are often conceptualised as passive decision-makers. The present study used the Coping in(More)
Women at high risk of familial ovarian cancer face a potentially difficult risk management choice between unproven ovarian cancer screening (OCS) and bilateral salpingo-oophorectomy (BSO). It is not fully understood why women who initially opt for OCS may later undergo BSO, nor what the impact of this may be. This study explored the catalysts for surgery(More)
BACKGROUND The UK Lung Cancer Screening (UKLS) trial is a randomised pilot trial of low-dose CT (LDCT) screening for individuals at high risk of lung cancer. We assessed the long-term psychosocial impact on individuals participating in the UKLS trial. METHODS A random sample of individuals aged 50-75 years was contacted via primary care. High-risk(More)
