Systematically Developing a Web-Based Tailored Intervention Promoting HPV-Vaccination Acceptability Among Mothers of Invited Girls Using Intervention Mapping.

Currently, the eHealth field calls for detailed descriptions of theory-based interventions in order to support improved design of such interventions. This article aims to provide a systematic description of the design rationale behind an interactive web-based tailored intervention promoting HPV-vaccination acceptability. The 6-step Intervention Mapping (IM) protocol was used to describe the design rationale.

Motivational and contextual determinants of HPV-vaccination uptake: A longitudinal study among mothers of girls invited for the HPV-vaccination.

Background: In the Netherlands, HPV-vaccination uptake among 12-year-old girls remains to be lower (61% in 2016) than expected. The present study is about 1) replicating the extent to which social-psychological determinants found in earlier cross-sectional studies explain HPV-vaccination intention, and 2) testing whether HPV-vaccination intention, as well as other social-psychological determinants, are good predictors of future HPV-vaccination uptake in a longitudinal design.

Methods: A random sample of mothers of girls invited for the vaccination in 2015 was drawn from the Dutch vaccination register (Praeventis) (N=36,000) and from three online panels (N=2483).

A primer on the use of cluster analysis or factor analysis to assess co-occurrence of risk behaviors.

Objective: The aim of this paper is to provide a guideline to a universal understanding of the analysis of co-occurrence of risk behaviors. The use of cluster analysis and factor analysis was clarified.

Method: A theoretical introduction to cluster analysis and factor analysis and examples from literature were provided.

Targets for primary prevention: cultural, social and intrapersonal factors associated with co-occurring health-related behaviours.

Objective: Multiple studies have identified clusters of co-occurring health-related behaviours. Little is known, however, about factors associated with such clusters. This study aims to identify these factors and to assess whether their effects are in accordance with the Theory of Triadic Influence (TTI).

[Reasons for having oneself vaccinated against HPV: implications for the future provision of information].

Objective: To examine which factors determined the participation in HPV vaccination programme in 2009 and 2010.

Design: Retrospective cross-sectional study.

Method: Random samples of Dutch girls who had been invited for the HPV vaccination programme in 2009 and 2010, as well as their mothers, were drawn from an Internet panel.

Determinants of HPV vaccination intentions among Dutch girls and their mothers: a cross-sectional study.

Background: The Dutch government recently added universal Human Papilloma Virus (HPV) vaccination for 12-year-old girls to the existing national immunization program. The participation rate for the initial catch-up campaign for girls aged 13 to 16 years in 2009 was lower (47%) than expected (70%). To inform future HPV information campaigns, this paper examines the social and psychological determinants of the HPV vaccination intentions of girls aged 13 to 16 years and their mothers who were targeted by the Dutch catch-up campaign of 2009.

Clustering of health and risk behaviour in immigrant and indigenous Dutch residents aged 19-40 years.

Objectives: Studies on the co-occurrence, 'clustering' of health and other risk behaviours among immigrants from non-industrialised countries lack until now. The aim of this study was to compare this clustering in immigrant and indigenous adults.

Methods: A representative sample (N = 2,982; response 71%) of the Dutch population aged 19-40, with 247 respondents from non-industrialized countries (Turkey, Morocco, Surinam, Netherlands Antilles), was asked about health behaviours (alcohol, smoking, drugs, unsafe sex, exercise, nutrition, sleep behaviour, traffic behaviour), and about rule-breaking behaviour and aggression.

Evaluation of an adoption strategy for a healthy diet programme for lower vocational schools.

This paper describes the evaluation of an adoption strategy for the school-based healthy diet programme Krachtvoer. Health promotion (HP) professionals from five Regional Public Health Services (RPHSs) in The Netherlands were asked to recruit a total of 25 schools to adopt the Krachtvoer programme in accordance with this strategy. Afterwards, they were interviewed about their adherence to and subjective evaluation of the strategy.

Clustering of health-compromising behavior and delinquency in adolescents and adults in the Dutch population.

Objective: This study investigates the clustering of a broad range of health-compromising and delinquent behaviors. We examine whether these behaviors belong to a single but broad cluster, 'risk-taking behavior', and whether the nature and degree of clustering in adolescents differs from that in adults.

Method: A representative sample (N=4395) of the Dutch population aged 12 to 40 (overall response rate 67%), was asked about various health-compromising behaviors, such as alcohol consumption, smoking, illegal drug use, unsafe sexual behavior, physical inactivity, poor nutrition (such as skipping breakfast and not eating fruit and vegetables), poor sleep behavior, unlawful traffic behavior, and delinquent and aggressive behavior.
