Alison Parkes MA PhD joined the unit in 2003 to work on teenagers’ use of sexual services using data from the SHARE programme. She has subsequently explored a number of other areas of teenage sexual wellbeing, including associations between teenage substance use and risky sex, quality of sexual/romantic relationships, use of contraception, same-sex relationships and family influences on sexual wellbeing. More recent work on younger age groups includes a study of the effects of television and electronic games on young children’s well-being, and research on middle-childhood problems associated with early sexual behaviour.
