I am interested generally in youth sexual development and childhood sexual experiences. As such, Dr. Lucia O’Sullivan and I have been involved in a number of projects attempting to understand normative sexual development. For example, in one study, we examined the developmental transitions from one type of sexual behaviour to another for male and female adolescents. In another, we investigated online extradyadic interactions (e.g., sexting, sending or receiving nude photos of a non-partner) among adolescents.
In addition, we are working together on a 4-year SSHRC funded project on early sexual experiences, particularly during childhood. Childhood sexual experiences (CSE) are not well understood (Larrson & Svedin, 2002), and long-term effects of such experiences have been the subject of widespread debate (e.g., Hyde, 2007; Tromovitch & Rind, 2007). Despite substantial research in the last 30 years (Maniglio, 2009; Poole & Wolfe, 2009), researchers remain unclear about the prevalence of various CSE as well as what differentiates normative experiences from abuse. Indeed, prevalence of specific types of CSE varies enormously across studies because of methodological differences, such as sampling variation, disparate definitions of experiences, or diversity of age criteria (Pereda, Guilera, Forns, & Gómez-Benito, 2009). Nevertheless, it is clear that a substantial percentage of people have sexual experiences during childhood. Given that researchers (e.g., Maniglio, 2009; Senn, Carey, & Vanable, 2008) have found variable psychosocial outcomes (e.g., internalizing and externalizing problems, resiliency) among individuals with some CSE (e.g., sexual abuse), it seems important to examine the range and prevalence of experiences, as well as the factors that uniquely predict normative, adverse, and positive outcomes. It is my hope that the work we are doing can contribute to an understanding of the nature and developmental course of these experiences. We have actively recruited university-aged participants and conducted anonymous, computerized surveys. We have also recently completed a phase two of the project in which we conducted in-person, follow-up interviews with individuals who endorsed having CSE. Over the next few years, we will be conducting large-scale surveys across Canada.
