About Hanneke Teunissen

[email protected]

Hanneke Teunissen was born in Boven-Leeuwen (Gelderland), the Netherlands. She studied psychology at Radboud University Nijmegen and attended the master Clinical Psychology. She completed her internship and master thesis at the Sint Maartenskliniek in Nijmegen and collaborated on several papers focusing on psychological support of patients suffering from rheumatic diseases. Subsequently, she attended the research master Behavioural Science at Radboud University. She completed her research internship at the Developmental Psychopathology program and studied the impact of self-control on attentional bias for alcohol cues among male heavy drinkers. She got her PhD at Radboud University. The goal of this project was to increase understanding of peer influence processes on adolescent alcohol use. She is currently employed as coding coordinator at the Developmental Psychopathology program and data manager at the Behavioural Science Institute.

Biography and Research Interests

Most of Hanneke’s research focused on the influence of peers on adolescents’ alcohol use. Although peer influence is considered to be one of the most important predictors of alcohol use in adolescence, it has not been rigorously tested and theoretical explanations are needed that focus on influence processes when young people are exposed to peers in drinking situations. Several innovative designs were used to study these peer influence processes, such as experimental designs to study causal relationships between young people’s drinking behavior and that of their peers, and diary studies to examine adolescents’ drinking behavior in their natural environment. Some of the central research questions were: 1) Which peers have the strongest influence? 2) Are peers able to increase as well as decrease adolescents’ alcohol use? 3) What is the role of individual differences in peer influence susceptibility? 4) Do drinker prototypes (i.e., stereotypical images of peers who drink or abstain) contribute to the prediction of adolescent alcohol use and are these prototypes malleable?

In her current position as coding coordinator, she focuses on observational research data, such as interactions between mother and child, or child and therapist, and trains and supervises coders to make accurate and reliable behavioral observations.
