Social networks and vaccination
Vaccines protect against life-threatening diseases and save millions of lives each year in people of all ages, but vaccination rates remain suboptimal and inequitable. Social networks, in which individuals are linked, offer capacity to transmit infectious diseases and protection against them by the diffusion of vaccination behavior. However, social networks are underutilized in public health strategies. This perspective paper advances a network-i…
Relevant determinants of Dutch patients’ informed decision-making and use of online access to medical records
Patient online access to medical records can foster patient empowerment and advance patient-centered healthcare. Despite high patient interest, user rates often remain low. While previous research has identified determinants influencing the adoption of online access, this study assessed the relevance of these determinants. By doing so, this study aimed to point towards measures to improve adoption efficiently. Furthermore, supporting patient-info…
Healthcare providers' intention to discriminate against people with HIV
Background: Healthcare providers' discrimination practices against people with HIV is a real challenge for control and prevention efforts. The study aims to explore the association between healthcare providers' intention to discriminate against people with HIV and HIV stigma-related constructs, their sociodemographic, and occupation characteristics in Sudan. Methods: A cross-sectional survey of healthcare providers was carried out in governmental…
A Mixed‐Methods Study Exploring the Feasibility of a Digital Combined Lifestyle Intervention for Patients With Post Covid‐19 Condition
INTRODUCTION: Low physical activity and poor dietary quality can negatively influence Covid-19 recovery and increase the risk and duration of post-Covid-19 condition (PCC). This proof-of-concept nested intervention study aimed to evaluate the feasibility of a digital personalised combined lifestyle intervention (CLI) in patients with PCC using a mixed-methods design, assessing compliance, experiences and perceived effectiveness. METHODS: A nested…
Relatives’ Perspectives on What Works to Reduce Problematic Alcohol Use in Older Adults
The rising prevalence of problematic alcohol use among older adults poses challenges to their health and also impacts their relatives. Given the important role relatives play, the objective of this study was to explore their perspectives on working elements (E) and mechanisms (M) within different contexts (C), both within and outside interventions, contributing to the outcome (O) of reducing (problematic) alcohol use among older adults. Guided by…

This realist evaluation protocol aims to elucidate the mechanisms and contextual factors influencing the FitBonus program's potential success in improving physical, mental, and social well-being, as well as perceived workability. The insights gained from this evaluation will offer actionable recommendations for optimizing the program's implementation and effectiveness. Additionally, by enhancing the understanding of how well-being interventions w…
Evaluating the Implementation of Home-Based Sexual Health Care Among Men Who Have Sex with Men
Home-based sexual health care (including self-sampling testing) could reduce barriers to clinic-based testing. This study systematically evaluated the implementation of home-based sexual health care ('Limburg4Zero') among men who have sex with men (MSM) in a mixed urban-rural region of the Netherlands. We systematically assessed implementation outcomes (contextual domains, population reached, effectiveness, adoption by health care providers (HCP)…
General population preferences for health-related protective behaviors during infectious disease emergencies
The challenge of change
Study habits drive a large portion of how university students study. Some of these habits are not effective in fostering academic achievement. To support students in breaking old, ineffective habits and forming new, effective study habits, an in-depth understanding of what students’ study habits look like and how they are both formed and broken is needed. Therefore, in this study, we explored these aspects among first-year university students in …
Exploring Risk and Protective Factors for Child Harm Amidst Exposure to Inter-parental Violence
There are limited insights into the differences in perspective between children and adult key-informants on the risk and protective factors for child harm from exposure to inter-parental violence. These differences were explored to inform the development of interventions to decrease levels of child harm. A phenomenological approach guided data collection the Social Construction of Reality Perspective was used to explain the study findings. Thirte…
Social activities in multidomain dementia prevention interventions
Based on these insights, we advocate for research that strengthens and accelerates the integration of social activities into multidomain interventions for dementia prevention. We propose several ways to achieve this: (a) by conducting mixed methods research to formulate a broadly accepted definition and instructions to measure social activities; (b) by focusing on promoting engagement in social activities beyond the intervention setting; and (c) …

Dutch Trial Register NTRNL6061 (13-01-2017). Registered at Overview of Medical Research in the Netherlands (OMON), via https://www.onderzoekmetmensen.nl
Outcomes of the combined lifestyle intervention CooL during Covid-19
As the CLI is considered usual health care that does not fall within the scope of the Dutch Medical Research Involving Human Subjects Act, this study was exempt from trial registration
Patients' experiences and perspectives regarding the use of digital technology to support exercise-based cardiac rehabilitation
These findings support the importance that is attributed to user-centred design methodologies in the conceptualisation and design of digital health interventions, and the imperative to develop solutions that are simple, accessible and that can be personalised according to the preferences and capabilities of the individual patient. Regarding data protection, data sharing and artificial intelligence, the findings indicate opportunity for informatio…
Evaluating use of web-based interventions
With the current increase in web-based interventions, the question of how to measure, and consequently improve engagement in such interventions is gaining more importance. Modern day web analytics tools make it easy to monitor use of web-based interventions. However, in this article, we propose that it would be more meaningful to first examine how the developers envisioned the use of the intervention to establish behavior change (i.e. intended us…
Hiv testing and counseling services in Kassala State, Sudan
HIV testing and counseling (HTC) services are essential for all HIV prevention and treatment interventions. Evidence is limited on the role of private healthcare providers in providing HTC services. This study assessed the relevant beliefs for intervention to enhance the intention to offer HTC services among private healthcare providers. A cross-sectional study included 387 private healthcare providers who completed a questionnaire about beliefs …
Intervention mapping as a guide to developing, implementing, and evaluating stigma reduction interventions
Stigmatization is a complex and deeply ingrained process, not easily amenable to change. The field of systematic behavior change can offer guidance for the improvement of stigma reduction efforts. In this article, we describe Intervention Mapping as a relevant approach for designing stigma reduction interventions. We demonstrate that, for stigma reduction to be effective, a number of actions are essential. We must (1) ascertain, at various socioe…
Citizen involvement in Covid-19 contact tracing with digital tools
Most interviewees hold a positive attitude towards self-led CT and using digital tools for this purpose. However, their intention for self-led CT may depend on various factors, such as prior experiences with regular CT, and their perceived self-efficacy to participate. Perspectives and needs of citizens should be considered for the future implementation of self-led CT in practice
How to use machine learning and fuzzy cognitive maps to test hypothetical scenarios in health behavior change interventions
Machine learning together with fuzzy cognitive maps can assist in building health behavior interventions with complex logic models. The testing of hypothetical scenarios may help interventionists finetune the intervention components thus increasing their potential effectiveness
Who is Exposed to HIV Prevention Interventions? An Assessment of Associated Factors Among Adolescent Girls and Young Women in South Africa
This study examined the prevalence of HIV risk factors and their association with intervention exposure among adolescent girls and young women (AGYW) living in six South African districts in which a combination HIV-prevention intervention was being implemented. A cross-sectional household survey was conducted from 2017 to 2018 among a representative sample of AGYW aged 15-24 years living in the six districts. We used an electronic questionnaire f…
Translation and cross-cultural adaptation of the children's exposure to domestic violence scale (Cedv) from English to Swahili
A 40 items Swahili scale was developed in a rigorous and systematic procedure. • Semantic, conceptual discrepancies and cultural equivalence were reckoned. • The scale enhanced children’s ability to elicit experiences of exposures to violence. • Swahili CEDV is a reliable scale to assess children’s exposure to violence. • Training to develop, adapt and validate childhood assessment scales is recommended. Most scales developed to assess childhood …
Introducing video consultations at public sexual health clinics in the Netherlands
Video consultations (in combination with remote STI testing) can benefit both public sexual health clinics (SHCs) and their clients. The Dutch public SHCs explored the extent to which video consultations are accepted and appreciated—compared to face-to-face consultations—by both young clients (under 25 years) and nurses who normally carry out consultations. A mixed-methods study, using online questionnaires and telephone interviews with both youn…
Psychosocial beliefs of health providers' intention and behavior of offering HIV testing and counseling services
Background: Diagnosis of people with HIV is vital in achieving the 95-95-95 global targets. The proportion of people with HIV who know they have HIV in Sudan is low. Promoting engagement of healthcare providers (HCPs) in offering HIV Testing and Counseling (HTC) services would improve the percentage of diagnosed people with HIV in the country. This study aims to assess the psychosocial beliefs associated with HCPs' intention and behavior to offer…
Identification of Relevant Sociocognitive Determinants Explaining Multiple Parental Sun Protection Behaviors
Background Adequate sun safety during childhood is crucial for decreasing skin cancer risk in later life. Although parents are an essential target group in applying sun protection measures for their children, insight into the determinants associated with their sun protection behaviors is limited. Aims This study aims to identify the most relevant determinants in predicting multiple parental sun protection intentions and behaviors in different sun…
The development of a culturally sensitive educational video
BACKGROUND: In the Netherlands, all women aged 30-60 years are invited to participate in the national cervical cancer screening programme, which is aimed at early detection and treatment of precancerous lesions. One fourth of the Dutch population has a migration background, with Turkish and Moroccan immigrants being the largest immigrant populations. Turkish- and Moroccan-Dutch women show lower screening participation rates and a higher incidence…
Decision-making, barriers, and facilitators regarding cervical cancer screening participation among Turkish and Moroccan women in the Netherlands
OBJECTIVES: Whether the lower Dutch cervical cancer (CC) screening participation of Turkish- and Moroccan-Dutch women is based on informed decision-making is unknown. Our aim was to explore how and why Turkish- and Moroccan-Dutch women decide to participate or not in the current Dutch CC screening programme as well as to learn their perceptions on self-sampling. DESIGN: Six focus group discussions were conducted between March and April 2019 with …
Gender norms associated with adolescent sexual behaviours in Uganda
The relationship between gendered power relations and sexual behaviours of adolescents has been limitedly explored in Uganda. A 2015 cross-sectional survey covering 16 purposively selected districts of Uganda assessed perceptions and associations of gender norms measured using the Gender Equitable Men scale and sexual behaviours among adolescents (N = 867). Findings indicate that behavioural intention to use contraception was moderately correlate…
Adolescents Who Intend to Change Multiple Health Behaviours Choose Greater Exposure to an Internet-delivered Intervention
Despite a growth of Internet-delivered interventions, exposure rates to such interventions are still low. In total, 35,104 adolescents participated in the E-MOVO project: an Internet-delivered lifestyle intervention aimed at multiple health behaviours. By means of multilevel analyses, we demonstrated the relationship between intention to change behaviour and adolescents' exposure to E-MOVO's functionalities. There was a clustering of intention to…

A conceptual framework for understanding and improving adolescents' exposure to Internet-delivered interventions
Although exposure is crucial to improve the public health impact of Internet-delivered interventions, it appears that in practice exposure to such interventions is low. Therefore, a conceptual framework, which incorporates elements of user experience of websites, is applied to Internet-delivered health behaviour change interventions aimed at adolescents and results from previous explorative research are incorporated. This framework, described fro…
Social desirability and self-reported health risk behaviors in web-based research
The studies at hand provided no convincing evidence to throw doubt on the usefulness of the Internet as a medium to collect self-reports on health risk behaviors
Intervening via chat
Mental health problems are highly prevalent among adolescents, but a majority of adolescents is reluctant to seek help at mental health services because of shame and lack of anonymity. Intervening via chat (i.e. offering online support) could be a solution to remove these barriers and to reach adolescents. The dimensions of the RE-AIM model (reach, efficacy, adoption, implementation and maintenance) served as a guiding principle for discussing th…
Evaluation of a school-based HIV prevention intervention among Yemeni adolescents
The school-based peer education intervention has succeeded in improving levels of knowledge on modes of transmission and prevention, and in decreasing levels of stigma and discrimination in a culturally conservative setting
Reminders in Web-Based Data Collection
Evidence-based insight on the effectiveness of reminders in web-based data collection in online panels is scarce. Thirty-eight studies were conducted in three different online panels to examine the effect of reminders on response rates, retention rates, and two facets of response quality (i.e., item omissions and response nondifferentiation). The studies were summarized using a meta-analytical approach including moderator tests ( N = 246,040). Re…
Just Another Manic Monday
The so-called “weekend effect” is a well-known phenomenon in the stock market (Keim & Stambaugh, 1984). This relates to significantly lower stock returns on Monday in comparison with other days of the week. It is suggested that this effect could be a result of traders’ fading optimism between Friday and Monday. Interestingly, similar “weekend effects” can also be found in health-related matters. The number of suicides, for example, is higher on M…
A Dutch panel study on the relation between structure of everyday life, daily hassles, and alcohol consumption
Daily hassles did not mediate the relationship between structure of everyday life and alcohol consumption
Exposures to war-related traumatic events and post-traumatic stress disorder symptoms among displaced Darfuri female university students
This study provides evidence for a relationship between traumatic war-related exposures and symptom rates of PTSD among AUW Darfuri female students. Findings are discussed in terms of AUW counseling service improvement
Using Google Analytics as a process evaluation method for Internet-delivered interventions
The study aimed to demonstrate the potential of Google Analytics as a process evaluation method for Internet-delivered interventions, using a website about sexual health as an example. This study reports visitors' behavior until 21 months after the release of the website (March 2009-December 2010). In total, there were 850 895 visitors with an average total visiting time (i.e. dose) of 5:07 min. Google Analytics provided data to answer three key …
Determinants of binge drinking in a permissive environment
Parents and adolescents should both be targeted in interventions to reduce alcohol use among adolescents. In particular, communication between parents and children should be improved, in order to avoid misconceptions about acceptable alcohol use. Further, adolescents should be supported to handle difficult social situations with peers where they feel obliged to drink. Additionally, revisions of policies towards a less permissive standpoint are ad…
Determinants and protective behaviours regarding tick bites among school children in the Netherlands
Most children have a good knowledge of ticks and the potential consequences of tick bites. Knowing persons who personally got ill after tick-bite is associated with a good knowledge score and leads to higher susceptibility and better appreciation of the need for body checks. Perceived severity is associated with a good knowledge score and with knowing persons who got ill after tick-bite. Is seems to be useful to additionally address children in h…
Using intervention mapping for the development of a targeted secure web-based outreach strategy named SafeFriend, for Chlamydia trachomatis testing in young people at risk
IM proved useful to develop an intervention for targeted Ct testing among young people. We believe this to be the first web-based outreach screening strategy which combines chain referral sampling with the delivery of targeted Ct testing to high risk young people within their sexual and social networks
An Agent-Based Social Network Model of Binge Drinking Among Dutch Adults
Binge drinking is a complex social problem linked to an array of detrimental health effects. While binge drinking in youth has been analyzed extensively using traditional methods (e.g., regressions analyses), the adult population has received less attention, and recent work has exemplified the potential for simulations to help scholars and practitioners better understand the problem. In this paper, we used agent-based social network models to tes…
Examining the relationship between completeness of teachers’ implementation of the Krachtvoer healthy diet programme and changes in students’ dietary intakes
Objective The goal of the current study was to examine if the completeness of programme implementation and the completeness of implementation of specific programme elements of the Dutch school-based healthy diet promotion programme Krachtvoer are related to short- and longer-term changes in students’ fruit, sweets and breakfast intakes. Design Data on students’ dietary intakes were collected 1–4 weeks and 6 months after programme implementation. …
The influence of father's child feeding knowledge and practices on children's dietary diversity
Infant and young child feeding has been recognised as an essential element to improve growth of children, especially in developing countries where malnutrition among children and its dire consequences are very prevalent. However, little attention has been paid on the influence of fathers on child feeding practices, although fathers are very important in raising well-adjusted, happy and successful children. Therefore, this study aimed to assess th…
A Web-based computer-tailored game to reduce binge drinking among 16 to 18 year old Dutch adolescents
Dutch Trial Register (NTR4048). Trial registered on 06/26/2013
A Web—Based Respondent Driven Sampling Pilot Targeting Young People at Risk for Chlamydia Trachomatis in Social and Sexual Networks with Testing
The screening strategy is feasible for targeting the hidden social network. However, uptake among men and recruitment of sex-partners is low and RDS stopped early. Future studies are needed to explore the sustainability, cost-effectiveness, and impact of strategies that target people at risk who are not effectively reached by regular health care
Perceptions of Sudanese women of reproductive age toward HIV/Aids and services for Prevention of Mother-to-Child Transmission of HIV
The study reveals that most of the women felt susceptible to HIV infection with perceived high severity; however, this perception has not translated into positive attitudes toward the importance of HIV testing during pregnancy. Because of anticipated stigma, women are not likely to disclose their HIV status. Further research should focus on gaining a more in-depth understanding of the psycho-social determinants and processes underlying the factor…
Identifying binge drinkers based on parenting dimensions and alcohol-specific parenting practices
Of the parenting dimensions and practices, rules are particularly informative in understanding drinking behaviour. Adolescents' perceptions and parents' reports are complementary as they can help identifying binge drinkers and non-binge drinkers respectively, indicating that surveying specific aspects of adolescent-parent dynamics can improve our understanding of complex addictive behaviours
Chlamydia trachomatis testing among young people
Young people perceive public stigma and anticipate self-stigma and shame in relation to CT testing, disclosure and encouraging others to test. People do test for CT, including those who anticipate stigma. To avoid stigmatizing reactions, stigma management strategies are applied, such as selective disclosure and the selective encouragement of others to test (i.e. only in a small trusted peer network). Care strategies that deploy sexual and social …
Web-based interventions to decrease alcohol use in adolescents
The results of this explorative study provide useful strategies to increase effectiveness and decrease drop-out in future interventions
Comparing the effect of a leaflet and a movie in preventing tick bites and Lyme disease in The Netherlands
Our results suggest that both the movie and the leaflet are valued and effective intervention tools for improving knowledge about tick bites and strengthening self-efficacy and intentions to perform protective behavior against ticks and LD . Achieving lasting effects, however, calls for more action

Education on tick bite and Lyme borreliosis prevention, aimed at schoolchildren in the Netherlands
The positive knowledge effects observed in the control group suggests the presence of a mere measurement effect related to completion of the questionnaire. The game did not outperform the leaflet or control group on all outcome measures. Therefore, the game may be of value as a complementary role, in addition to other media, in child-specific public health education programs on ticks and LB. This trial was retrospectively registered on October 21…
