BACKGROUND Although effective smoking cessation interventions exist, information is limited about their cost-effectiveness and cost-utility. OBJECTIVE To assess the cost-effectiveness and cost-utility of an Internet-based multiple computer-tailored smoking cessation program and tailored counseling by practice nurses working in Dutch general practices(More)
The mutual influence of smoking behavior and friendships in adolescence is studied. It is attempted to disentangle influence and selection processes in reciprocal and non-reciprocal friendships. An actor-based model is described for the co-evolution of friendship networks and smoking behavior. This model considers alternative selection and influence(More)
The European Smoking Prevention Framework Approach (ESFA) study in six countries tested the effects of a comprehensive smoking prevention approach after 24 (T3; N = 10,751) and 30 months (T4; N = 9,282). The programme targeted four levels, i.e. adolescents in schools, school policies, parents and the community. In Portugal, 12.4% of the T1 non-smokers in(More)
BACKGROUND Recent calls have been made to consider both environmental factors and individual-level factors in the explanation of physical activity (PA). The present study tested a conceptual model that integrated past PA, relevant environmental-level and individual-level factors and their associations with adolescent PA, using the tenets of the Theory of(More)
BACKGROUND The Active Plus project is a systematically developed theory- and evidence-based, computer-tailored intervention, which was found to be effective in changing physical activity behavior in people aged over 50 years. The process and effect outcomes of the first version of the Active Plus project were translated into an adapted intervention using(More)
BACKGROUND This study provides insight into the long-term efficacy (i.e. 12 month results) of the Web-based or print-delivered tailored Active Plus intervention (with and without environmental approach) to promote physical activity (PA) among the over-fifties. Differences in effect among subgroups are studied as well. METHODS Intervention groups (i.e.(More)
BACKGROUND Although the number of smokers has declined in the last decade, smoking is still a major health problem among youngsters and adolescents. For this reason, there is a need for effective smoking prevention programmes targeting primary school children. A web-based computer-tailored feedback programme may be an effective intervention to stimulate(More)
BACKGROUND Computer tailoring and motivational interviewing show promise in promoting lifestyle change, despite few head-to-head comparative studies. PURPOSE Vitalum is a randomized controlled trial in which the efficacy of these methods was compared in changing physical activity and fruit and vegetable consumption in middle-aged Dutch adults. METHODS(More)
BACKGROUND The aim of this study was to explore the working mechanisms of a computer tailored physical activity intervention for older adults with environmental information compared to a basic tailored intervention without environmental information. METHOD A clustered randomized controlled trial with two computer tailored interventions and a(More)
The present study examined the association between adolescents' personality traits and smoking, and tested whether this association was moderated by birth order or gender. Participants were 832 Dutch siblings aged 13 to 17 years participating at baseline assessment (T1) and at follow-up 12 months later (T2). Personality was assessed by applying a(More)
