..To be able to learn from successes and failures of such interventions, integral written and published reports are needed...

..Hence, retirees are an important target group for weight gain prevention programmes, as described in the present paper...

..Furthermore, response efficacy, i.e., the individual's beliefs about the outcome of participation, and social support proved to be concepts that were associated with participation...

..The current evidence base is reviewed regarding potential moderating factors in the effectiveness of environmental interventions aimed at diet and/or physical activity of children and adolescents...

..Additionally, associations between the mean scale scores of the instrument and children's body mass index (BMI) were assessed...

..abstract:..

..A general lack of reporting underlying theoretical models for behaviour change was observed as well as the inclusion of linkage groups and strategies to promote empowerment...

..Consequences of the identified role of habit and parental norms in the interplay between sedentary behaviour and consumption of sugar-sweetened beverages among adolescents are discussed...

..Finally, we argue that the traditional paper-and-pencil survey is still the most reliable and practical data collection method. However, pilot studies applying computerised adaptive methods to determinants of EBRBs are encouraged...

..This paper aims to provide an overview of different theoretical approaches in the study of determinants of energy balance-related behaviors (EBRBs)...

..Two lines of psychological research have attempted to spell out the stages of adolescent smoking initiation. The first has focused on behavioral stages of smoking initiation, while the second line emphasized motivational stages...

..Consequences of these results for the interpretation of earlier studies on the influence of parenting practices are discussed, and a research model is proposed for future studies of parental influences on adolescent dietary behaviours...

..Although effect sizes were small to moderate, unique predictors of transitions from the various stages were identified. Implications of the findings are discussed...

..Finally, it is argued that smoking prevention interventions should aim at influencing the image of nonsmoking by using mass media interventions and restrictive policies...

....

..The theory-driven assessment of the process of adolescent smoking initiation may contribute to the development of a generally accepted measure of adolescent smoking initiation...

..To gain more insight into reasons some adolescents do, and others do not, proceed to advanced levels of smoking behavior, a continuum in which two categories of ex-smoking are proposed is examined...

....

..Actual exposure to CT interventions is not living up to its high expectations, as only a (limited) proportion of the target group is actually using these programs...

..This effectiveness study is called GO4fit...

..Our randomized controlled trial compares the expenses and effects of the 'supervised exercise programme' with those of the less intensively supervised 'start-up exercise programme'...

..Findings indicate the importance of acknowledging parental feeding styles in future research efforts as well as in the development of family-based interventions promoting healthy eating habits among children...

..The findings suggest opportunities for preventive interventions focussing on parents of young children, and indicate that different approaches to parenting practice interventions are needed for different types of children...

..Future research should explore possible mediators between personality and health behavior in adolescents...

....

..This is crucial because lifestyle habits are formed at an early age and track in later life. This study is the first to examine EBRB clustering in children as young as 2 years...

..The direct effects of practices and personality are noteworthy from a theoretical perspective. Implications for obesity prevention interventions are discussed...

..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 Planned Behavior (TPB)...

..The aim of this study is to test and compare the effectiveness of two different tailoring strategies for changing lifestyle compared to a control group using a multiple health behaviour web-based approach...

..e. physical activity (PA) and sedentary screen-based behavior) in 5-year-old children, as well as the longitudinal association of these patterns with weight status (BMI and overweight) development up to age 8...

..The current study examined clustering of dietary intake and activity behaviours (i.e. physical activity (PA) and sedentary behaviour) in 5-year-old children, as well as the longitudinal association with BMI and overweight development...

..The goal of this study was to identify barriers that Dutch youth health care (YHC) professionals perceive when referring parents of overweight children to an obesity prevention intervention...

..Factors that relate to the initiation of adolescent smoking are found among the concepts of attitude, social norms, social pressure and self-efficacy beliefs...

..Finally, the stages of change mediated the relation between previous and future helping behavior. Initial support was found for the applicability of the stages of change construct for helping behavior by non-professional bystanders...

..The results from the JUMP-in study show the importance of intervention designs that focus on a theory-based mix of relevant environmental and social cognitive factors...

..Our findings also confirm the link between smoking and alcohol use suggesting that the prevention of these two behaviours should be complementary...

..Although physical activity has been associated negatively with smoking in adolescence, the association is not well understood...

..To assess the criterion validity of paper-and-pencil vignettes to assess guideline adherence by physiotherapists in the Netherlands. The evidence-based physiotherapy practice guideline for low back pain was used as an example...
