Clustering of diet- and activity-related parenting practices: cross-sectional findings of the INPACT study.

Background: Various diet- and activity-related parenting practices are positive determinants of child dietary and activity behaviour, including home availability, parental modelling and parental policies. There is evidence that parenting practices cluster within the dietary domain and within the activity domain. This study explores whether diet- and activity-related parenting practices cluster across the dietary and activity domain.

Associations of parental feeding styles with child snacking behaviour and weight in the context of general parenting.

Objective: To examine cross-sectional and longitudinal (one-year follow-up) associations of parental feeding styles with child snacking behaviour and weight in the context of general parenting, taking into account the multidimensionality of the controlling feeding style.

Design: Linear regression analyses were performed. Parents completed a questionnaire to measure five feeding style dimensions (Instrumental Feeding, Emotional Feeding, Encouragement, Overt Control and Covert Control) and children's fruit, energy-dense snack and sugar-sweetened beverage (SSB) intakes.

Associations of children's appetitive traits with weight and dietary behaviours in the context of general parenting.

Background: Individual variations in child weight can be explained by genetic and behavioural susceptibility to obesity. Behavioural susceptibility can be expressed in appetite-related traits, e.g.

Clustering of food and activity preferences in primary school children.

This study examined clustering of food and activity preferences in Dutch primary school children. It also explored whether the preference clusters are associated with child and parental background characteristics and with parenting practices. Data were used from 1480 parent-child dyads participating in the IVO Nutrition and Physical Activity Child cohort (INPACT).

Video game addiction test: validity and psychometric characteristics.

The study explores the reliability, validity, and measurement invariance of the Video game Addiction Test (VAT). Game-addiction problems are often linked to Internet enabled online games; the VAT has the unique benefit that it is theoretically and empirically linked to Internet addiction. The study used data (n=2,894) from a large-sample paper-and-pencil questionnaire study, conducted in 2009 on secondary schools in Netherlands.

Is there an association between the home food environment, the local food shopping environment and children's fruit and vegetable intake? Results from the Dutch INPACT study.

Objective: To examine: (i) the association between home availability of fruit and vegetables and children’s fruit and vegetable intake; (ii) the association between parental perception of the local food shopping environment and the home availability of fruit and vegetables; and (iii) whether the home availability of fruit and vegetables mediates the association between parental perception of the local food environment and children’s fruit and vegetable consumption.

Design: Cross-sectional study.

Setting: A total of ninety-one primary schools in the Netherlands.

Parental and child fruit consumption in the context of general parenting, parental education and ethnic background.

This study examines the association between parental and child fruit consumption in the context of general parenting, parental education and ethnic background. A cross-sectional study was performed among 1762 parent-child dyads. Mean age of the children was 8 years.

Psychological control by parents is associated with a higher child weight.

Objective: In this examination of the association between parenting style and child weight, the neglected concept of 'psychological control' has been added to the generally accepted parenting dimensions 'support' and 'behavioural control'. Also explored is whether the potential association between parenting and child weight is moderated by socio-demographic variables (child's age/ethnicity, and parent's education level).

Methods: A cross-sectional study was performed among 1,665 parent-child dyads.

Online video game addiction: identification of addicted adolescent gamers.

Aims: To provide empirical data-driven identification of a group of addicted online gamers.

Design: Repeated cross-sectional survey study, comprising a longitudinal cohort, conducted in 2008 and 2009.

Setting: Secondary schools in the Netherlands.

Compulsive Internet use: the role of online gaming and other internet applications.

Purpose: Increasing research on Internet addiction makes it necessary to distinguish between the medium of Internet and its specific applications. This study explores the relationship between time spent on various Internet applications (including online gaming) and Compulsive Internet Use in a large sample of adolescents.

Methods: The 2007 (N=4,920) and 2008 (N=4,753) samples of a longitudinal survey study among adolescents were used, as well as the 2007-2008 cohort subsample (N=1421).

Trends, motivations and settings of recreational cocaine use by adolescents and young adults in the Netherlands.

Background: In recent years the use of powder cocaine among socially integrated adolescents and young adults has normalised. It is no longer an extraordinary drug to use in trendy/innovative as well as mainstreams clubs. Not much research has been done on motivations for and settings in which this cocaine use takes place.

Self-comparison processes, prototypes, and smoking onset among early adolescents.

Background: Research has shown that social images or prototypes of smoking peers play a role in adolescents' decisions to start smoking. To devise effective prevention measures, specific information is needed about how adolescents evaluate characteristics associated with smoker prototypes. Such evaluation is assumed to occur through self-comparison processes, that is, 'self-consistency' and 'self-enhancement' motivations.
