Furthermore, our results highlight that fostering school personnel's acceptance of the intervention and planning goal-oriented actions are crucial elements in optimizing adoption promotion of eHealth programs in schoo…
Please, see me’; Informal and professional support of students with relatives with addiction problems: A three-year longitudinal qualitative study
It is recommended to train educational and healthcare professionals to recognize the support needs of young people with relatives with addiction problems, to help them cope, or to refer them adequately. We also suggest broadening the scope of professional support offered to AFMs, including body-oriented and cultural interventions
Development of community strategies supporting brief alcohol advice in three Latin American countries: A protocol
Brief alcohol advice offered to patients was shown to be a clinically- and cost-effective intervention to prevent and manage alcohol-related health harm. However, this intervention is not yet optimally implemented in practice. A suggested strategy to improve the implementation of brief alcohol advice is through community actions which would enhance the environment in which primary healthcare providers must deliver the intervention. However, there…

Country and policy factors influencing the implementation of primary care-based alcohol screening: A comparison of Colombia, Mexico and Peru
Researchers and practitioners recognise the importance of context when implementing healthcare interventions, but the influence of wider environment is rarely mapped. This paper identifies the country and policy-related factors potentially explaining the country differences in outcomes of an intervention focused on improving detection and management of heavy alcohol use in primary care in Colombia, Mexico and Peru. Qualitative data obtained throu…
Smokers’ strategies to reduce tobacco spending: Self-reported use and differences across subgroups. Findings from the International Tobacco Control (ITC) Netherlands Survey
The majority reported using strategies to reduce spending or that price played a role in their decision to quit. Reducing consumption was the most reported strategy. Low-income smokers were more likely to reportedly reduce consumption, buy cheaper products, or quit. Price policies have the potential to reduce socioeconomic inequalities in smoking. To discourage price-minimising behaviours, such as switching to cheaper products, reducing price dif…
Psychosocial determinants of consistent condom use among university students in Sudan: Findings from a study using the Integrated Change Model
Unprotected sex is common among university students in Sudan, thus increasing risks for sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV). As little is known about the psychosocial determinants of consistent condom use among this population, this study was designed to identify them. The Integrated Change Model (ICM) was applied in a cross-sectional design to identify in 218 students (aged 18-25 years) from Khartoum which…
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…
Too old for technology? Stereotype threat and technology use by older adults
Older adults are often stereotyped as having less technological ability than younger age groups. As a result, older individuals may avoid using technology due to stereotype threat, the fear of confirming negative stereotypes about their social group. The present research examined the role of stereotype threat within the Technology Acceptance Model (TAM). Across two studies, experiencing stereotype threat in the technological domain was indirectly…

Examining socio-cognitive factors and beliefs about mindful eating in healthy adults with differing practice experience: A cross-sectional study
Results indicate that individuals need to be treated differently when promoting ME with respect to their psychosocial characteristics, rather than as a single group with homogenous baseline beliefs, abilities, support, and motivation. Future longitudinal research should examine which determinants are predictors of ME to better tailor program contents
Costs of an Alcohol Measurement Intervention in Three Latin American Countries
Alcohol measurement in health care settings is an effective intervention for reducing alcohol-related harm. However, in many countries, costs related to alcohol measurement have not yet been transparently assessed, which may hinder its adoption and implementation. Costs of an alcohol measurement programme in three upper-middle-income Latin American countries were assessed via questionnaires and compared, as part of the quasi-experimental SCALA st…
Covid-19 Vaccine Hesitancy: The Role of Information Sources and Beliefs in Dutch Adults

A qualitative study of parental associations and beliefs regarding the HPV vaccination for Dutch boys
Public campaigns regarding (the HPV) vaccination should improve (parental) awareness about the virus and the vaccination, and increase knowledge. Moreover, it should address concerns regarding vaccination and be transparent about decision making. For example, a rationale why HPV vaccination is needed for boys who turn 10 years and its advantage to reducing risks for boys to contract HPV related cancers should be provided
Psychosocial Determinants of Premarital Sexual Practices among University Students in Sudan
Sudan is one of the Islamic countries where extramarital sex is religiously forbidden and socially unacceptable. However, increasing numbers of university students become engaged in premarital sex practices, which increases their risk of contracting STIs, including HIV, and puts them into conflicts with their religious beliefs. As little is known about the motivations for abstinence from premarital sex, this study aimed to identify these psychoso…

Self-efficacy as a Potential Moderator of the Effects of Framed Health Messages
This study focuses on self-efficacy as a potential moderator of the effects of gain- and loss-framed health messages. Undergraduate students ( N = 124) received a gain- or loss-framed message about consuming ecological meat. The data revealed that for participants high in self-efficacy, the gain-framed message resulted in consuming more ecological meat than the loss-framed message. Moreover it was found that - within the gain-frame condition - pa…
Sociocognitive Predictors of Condom Use and Intentions Among Adolescents in Three Sub-Saharan Sites
Many HIV intervention programs in sub-Saharan Africa have applied social cognitive theories such as the theory of planned behavior. However, a recent sub-Saharan African review was unable to show increased effectiveness for theory-based interventions. This study assessed whether the predictive value of attitudes, subjective norms, self-efficacy, and intention was similar to studies in Europe and the U.S., and whether there were differences betwee…
Adolescents’ Beliefs About Forced Sex in KwaZulu-Natal, South Africa
Gender-based violence has serious consequences for the psychological, physical, and sexual well-being of both men and women. Various gender roles, attitudes, and practices in South Africa create an environment that fosters submission and silence in females and hegemony and coercion in males. One of the expressions of this power inequity is a high prevalence of forced sex, which in its turn is associated with higher risk of HIV infection. This stu…
Preaching to the choir? The influence of personal relevance on the effects of gain- and loss-framed health-promoting messages
This article examines the moderating influence of personal relevance on the persuasive effects of gain- and loss-framed messages. We assessed current behaviour as a proxy for personal relevance, provided 169 participants with gain- and loss-framed messages advocating skin self-examination (SSE) and assessed intention to engage in SSE as the outcome measure. The results showed that loss-framed information was more persuasive than gain-framed infor…

Distinct pathways to persuasion: The role of affect in message‐framing effects
Health‐promoting messages can be framed in terms of the gains that are associated with healthy behaviour (gain frame) or the losses that are associated with unhealthy behaviour (loss frame). In the present research, we examined the role of positive and negative affect in the persuasive effects of gain‐ and loss‐framed health‐promoting information. Experiment 1 ( N = 98) showed that gain‐framed information resulted in higher levels of information …
Avoidance orientation moderates the effect of threatening messages
This study investigated the influence of individual differences in people's dispositional avoidance orientation on the persuasive effects of low- and high-threat messages promoting moderate drinking. First, participents ( N = 99) individual differences in avoidance orientation were assessed, after which they were provided with either high- or low-threat messages about the consequences of drinking too much alcohol. The primary outcome measures wer…
The Relations Between Parents' Smoking, General Parenting, Parental Smoking Communication, and Adolescents' Smoking
The present study examined whether the associations between general parenting practices (i.e., support, behavioral control, and psychological control) and parental smoking on the one hand and older and younger siblings' smoking on the other were mediated by parental smoking communication (i.e., frequency and quality of parent–adolescent communication concerning smoking-related issues). The focus of this paper was on examining whether these associ…
The influence of self‐efficacy on the effects of framed health messages
Health promoting messages can be framed in terms of the gains that are associated with healthy behaviour, or the losses that are associated with unhealthy behaviour. In this study, we examined the influence of self‐efficacy to quit smoking on the effects of gain framed and loss framed anti‐smoking messages in a randomized controlled trial among 539 adult smokers. Participants with a high self‐efficacy to quit smoking reported higher levels of mot…
Exploring Determinants of Condom Use among University Students in Sudan
Increasing numbers of university students in Sudan are at risk of contracting HIV because of their engagement in condomless sex. A comprehensive and culturally accepted condom promotion program could potentially reduce this threat substantially. However, little is known about the sociocognitive determinants of condom use in this population: information that is required to develop such HIV prevention programs. Therefore, in August 2014, we conduct…

Predicting safe sex: Assessment of autoregressive and cross-lagged effects within the Theory of Planned Behavior
Despite its popularity, few studies have assessed the temporal stability and cross-lagged effects of the Theory of Planned Behavior factors: Attitude, subjective norms and self-efficacy. For this study, 298 adolescent learners from KwaZulu-Natal, South Africa, filled out a Theory of Planned Behavior questionnaire on teenage pregnancy at baseline and after 6 months. Structural equation modeling showed that there were considerable cross-lagged effe…
Self-efficacy: The third factor besides attitude and subjective norm as a predictor of behavioural intentions
When explaining (health) behaviour much attention is paid to attitudes and subjective norms. It is assumed that self-efficacy expectations will significantly increase the prediction of behavioural intentions. Therefore, the self-efficacy concept from Bandura's social learning theory has been integrated together with the two factors of the Fishbein-Ajzen model within one model to explain behavioural intentions. Results of a hierarchical regression…

Challenges to the peer influence paradigm: Results for 12–13 year olds from six European countries from the European Smoking Prevention Framework Approach study
Smoking uptake in this age cohort may be more strongly influenced by personal and parental influences than initially believed. Hence, social inoculation programmes teaching youngsters to resist the pressures to smoke may be less appropriate if youngsters have a positive attitude towards smoking, associate smoking with various advantages and look for peers with similar values. For this group attitudes towards smoking may thus guide future friend s…
Smoking in immigrants: Do socioeconomic gradients follow the pattern expected from the tobacco epidemic
The prevalence figures and educational associations suggest that the socioeconomic gradient changes in earlier stages of the epidemic in immigrant populations than in the Western host populations, particularly in men. This provides indications to suggest that smoking prevention measures in male immigrant groups need to be tailored to lower socioeconomic groups in particular throughout the tobacco epidemic, and to higher socioeconomic groups among…
Bi-directional relations between anti-smoking parenting practices and adolescent smoking in a Dutch sample
Further research is needed to establish which aspects of parenting can be effective in deterring adolescent smoking. This study emphasizes the need for caution in interpreting cross-sectional research findings relating parenting to adolescent smoking
