Relevant theoretical and empirical insights regarding the development of interventions to promote physical activity in young people are overviewed. It is argued that physical activity-promoting programmes should be based on a systematic approach combining empirical findings, theoretical insights, and practical considerations. Successful health promotion interventions to increase physical activity typically consist of strategies to improve intra-personal determinants of physical activity, as well as environmental strategies that facilitate the behaviour, break unhealthy habits, or sustain healthy ones. The Intervention Mapping protocol can be a helpful tool in the systematic development, implementation, diffusion, and evaluation of interventions aimed at the promotion of physical activity in young people.

Implementation of health education programs is often inadequately considered or not considered at all in planning, developing and evaluating interventions. With the focus being predominantly on the adoption stage, little is known about the factors influencing the implementation and continuation stages of the diffusion process. This study contributes to the understanding of factors that promote or impede each stage of the diffusion process in the school setting using the sex education program Long Live Love (LLL) as an example. A survey integrating different diffusion-related concepts was completed by 130 teachers. Results showed that teacher curriculum-related beliefs were associated with all stages in the diffusion process. Although adoption of LLL was predominantly related to teacher curriculum-related beliefs, implementation completeness and fidelity and continued use of LLL were also enhanced by contextual factors, namely teacher training and interactive context variables (school policy, governing body support and student response), respectively. The results of this study can be used to optimize the adoption, implementation and continuation of school-based (sexual) health promotion programs.

This study explored, from a public health perspective, factors that contribute to inconsistent condom use by men in Curacao through semi-structured face-to-face interviews with 21 heterosexual men. The findings show that there is an important disconnect between what is considered culturally appropriate sexual behaviour for men and women and condom use, that diverging from prescribed notions of masculinity and femininity in order to use condoms consistently is difficult, and that condom use is particularly problematic in the context of concurrent partnerships and sexual economic exchanges. Participants further reported that Caribbean family structures, whereby mothers assume the role as primary caregiver and fathers contribute biologically but, to a much lesser extent socially, also have an impact on condom use. Additionally, consistent condom use was reported to be impeded by a cultural taboo on talking seriously about sex and sexual health. In their totality, findings provide important input from men for the development of sexual health promotion interventions that are cognizant of the cultural context in which inconsistent condom use occurs, and that are geared not only to the individual level but also to the interpersonal and structural levels.

Risk for sexually transmitted infections (STIs) is perceived to be less when the potential partner is sexually appealing. Is it possible that cleanliness of the room in which intercourse takes place also affects perceived risk for STIs? In scenario studies, participants were asked to imagine having had unsafe sex with a person they just met in that person's apartment (Study 1) or in a hotel room (Study 2) and that the next day they wake up in a room that is either quite dirty or very clean. Participants in the dirty room condition rated their susceptibility to STI higher, and had lower intentions to act the same way again. Results are discussed in terms of deductive processes, emotions, and magical contagion.

Objectives Having condoms available has been shown to be an important predictor of condom use. We examined whether or not personal norm and goal enjoyment contribute to predicting having condoms available in the context of cognition specified by the theory of planned behaviour (TPB). Design Prospective survey study, with a baseline and follow-up measurement (at 3 months). Methods Data were gathered using an online survey. In total 282 adolescents (mean age = 15.6, 74% female adolescents) completed both questionnaires. At baseline, demographics, sexual experience, condom use, TPB variables, descriptive norm, personal norm, and enjoyment towards having condoms available were measured. At T2 (3 months later) having condoms available was measured. Direct and moderating effects of personal norm and goal enjoyment were examined by means of hierarchical linear regression analyses. Results Regression analyses yielded a direct effect of self-efficacy and personal norm on condom availability. In addition, moderation of the intention-behaviour relation by goal enjoyment added to the variance explained. The final model explained approximately 35% of the variance in condom availability. Conclusions Personal norm and goal enjoyment add to the predictive utility of a TPB model of having condoms available and may be useful intervention targets. Statement of contribution What is already known about this subject? Having condoms available is an important prerequisite for actual condom use. The theory of planned behaviour has successfully been applied to explain condom availability behaviour. The theory of planned behaviour has been criticized for not adequately taking into account affective motivation. What does this study add? Personal norm and goal enjoyment add to the predictive utility of the model. Personal norm explains condom availability directly, enjoyment increases intention enactment. Personal norm and goal enjoyment therefore are useful intervention targets. © 2012 The British Psychological Society.

Objective: Health information helplines have an important function in health education, prevention and counseling. Information and help services are increasingly provided online. This study focuses on the differences and similarities between online help services and telephone services.Methods: The telephone service of the Dutch AIDS STI helpline was compared to its e-mail equivalent. After consulting the helpline service, both callers and e-mailers (N-tot = 455) were asked to participate in a survey that evaluated their background characteristics, contacting reasons, and satisfaction with the specific service and information received. The survey also included questions regarding the advice received from the helpline. A follow-up measure 4 weeks after the baseline survey evaluated to what extent clients acted upon the advice.Results: The study shows that both services are positively evaluated and are equally persuasive in their counseling. Differences between callers and e-mailers were found regarding background characteristics, content of the consultation, satisfaction, and the advice received.Conclusion: It can be concluded that online health information services are an important addition to, but not a replacement for, the traditional telephone helplines.Practice implications: In order to provide an optimal health service to a wide public, both online and telephone counseling should be offered.

The objective of this project was to develop a theory- and evidence-based adolescent smoking cessation intervention using both new and existing materials. We used the Intervention Mapping framework for planning health promotion programmes. Based on a needs assessment, we identified important and changeable determinants of cessation behaviour, specified change objectives for the intervention programme, selected theoretical change methods for accomplishing intervention objectives and finally operationalized change methods into practical intervention strategies. We found that guided practice, modelling, self-monitoring, coping planning, consciousness raising, dramatic relief and decisional balance were suitable methods for adolescent smoking cessation. We selected behavioural journalism, guided practice and Motivational Interviewing as strategies in our intervention. Intervention Mapping helped us to develop as systematic adolescent smoking cessation intervention with a clear link between behavioural goals, theoretical methods, practical strategies and materials and with a strong focus on implementation and recruitment. This paper does not present evaluation data.

Various authors (e.g. Kahnemann, D., & Tversky, A. (1982). The simulation heuristic. In D. Kahnemann, P. Slovic, & A. Tversky (Eds.), Judgment under uncertainty: Heuristics and biases (pp. 201-208). New York, NY: Cambridge University Press) have suggested that imagining an event and its consequences influences the perceived likelihood that it might happen in reality (simulation heuristic). A scenario - a description of how a certain activity can lead to a certain outcome - may stimulate one to imagine the outcomes and may influence one's likelihood judgement. The present research studied the effect of risk scenarios on perceptions of susceptibility to sexually transmitted infections and the role of imaginability therein. In a randomised experimental study, we examined the effects of a prefabricated risk scenario and a self-constructed risk scenario against a non-message condition on perceived susceptibility to get infected with Chlamydia. Participants considered themselves more susceptible to Chlamydia after writing their own risk scenario but not after reading the prefabricated risk scenario. The imaginability of the event seemed to mediate the effect of self-constructed scenario information on perceived susceptibility. Recommendations for health education practices are discussed.

Thirty years after the first diagnosis, people living with HIV (PLWH) around the world continue to report stigmatizing experiences. In this study, beliefs contributing to HIV-related stigma in African and Afro-Caribbean diaspora communities and their cultural context were explored through semi-structured interviews with HIV-positive (N=42) and HIV-negative (N=52) African, Antillean and Surinamese diaspora community members in the Netherlands. Beliefs that HIV is highly contagious, that HIV is a very severe disease, and that PLWH are personally responsible for acquiring their HIV infection were found to contribute to HIV-related stigma, as did the belief that PLWH are HIV-positive because they engaged in norm-violating behaviour such as promiscuity, commercial sex work, and, for Afro-Caribbean diaspora, also homosexuality. These beliefs were found to be exacerbated and perpetuated by cultural taboos on talking about HIV and sexuality. HIV-related stigma reduction interventions should focus on changing these beliefs and breaking cultural taboos on HIV and sexuality in a manner that is participatory and consistent with the current theory and empirical findings. © 2011 John Wiley & Sons, Ltd.

BACKGROUND: This study investigated the possibility of rerecruiting lapsed blood donors. Reasons for donation cessation, motivation to restart donation, and modifiable components of donation motivation were examined. We distinguished between lapsed donors who had passively withdrawn by merely not responding to donation invitations and donors who had contacted the blood bank to actively withdraw. STUDY DESIGN AND METHODS: A cross-sectional survey was sent to 400 actively lapsed donors and to 400 passively lapsed donors, measuring intention to restart donation and psychological correlates of restart intention. The data were analyzed using multiple regression analyses. RESULTS: The response rate among actively lapsed donors was higher than among passively lapsed donors (37% vs. 25%). Actively lapsed donors typically ceased donating because of physical reactions, while passively lapsed donors quit because of a busy lifestyle. Nonetheless, 51% of actively lapsed responders and 80% of passively lapsed responders were willing to restart donations. Multiple regression analysis showed that, for passively lapsed donors, cognitive attitude was the strongest correlate of intention to donate in the future (β=0.605, p

HIV-related stigma, psychological distress, self-esteem, and social support were investigated in a sample comprising people who have concealed their HIV status to all but a selected few (limited disclosers), people who could conceal but chose to be open (full disclosers), and people who had visible symptoms that made concealing difficult (visibly stigmatized). The visibly stigmatized and full disclosers reported significantly more stigma experiences than limited disclosers, but only the visibly stigmatized reported more psychological distress, lower self-esteem, and less social support than limited disclosers. This suggests that having a visible stigma is more detrimental than having a concealable stigma. Differences in psychological distress and self-esteem between the visibly stigmatized and full disclosers were mediated by social support while differences between the visibly stigmatized and limited disclosers were mediated by both social support and stigma. These findings suggest that social support buffers psychological distress in people with HIV.

Dit artikel beschrijft de evaluatie van Uma Tori, een soa/hiv preventie interventie voor vrouwen van Surinaamse en Antilliaanse afkomst in Den Haag, Amsterdam en Rotterdam. Er wordt beargumenteerd hoe verschillen in implementatie mogelijk samenhangen met effectiviteit. Dit artikel gaat ook vanuit de eerder uitgevoerde proces- en effectevaluatie in op mogelijke oorzaken voor de verschillen in het huidige gebruik van de interventie. Uit recent onderzoek blijkt namelijk dat Uma Tori in Rotterdam nog steeds gebruikt wordt en is uitgebreid naar andere doelgroepen. Maar in Amsterdam is dit niet het geval. De interventie was gericht op het vergroten van bewustwording van seksuele risico’s en machtsverhoudingen binnen relaties en op het verbeteren van vaardigheden om bewuste keuzes te maken voor veilige seksuele relaties. Effecten van de interventie werden gemeten met een pre-post-test design. Daarnaast werd een procesevaluatie uitgevoerd met behulp van logboeken, focus groep discussies en interviews. De uitkomsten van de effectevaluatie lieten positieve effecten zien op kennis, risicoperceptie, subjectieve norm, seksuele assertiviteit en intentie om veilig vrijen te onderhandelen met de partner. Na de interventie gaven deelneemsters van Uma Tori aan meer met hun partners te communiceren over veilig vrijen. In Rotterdam waren de effecten het grootst. Uit de procesevaluatie bleken aanzienlijke verschillen in implementatie te bestaan tussen de drie steden, zoals de wervingstrategie voor deelnemers, de beschikbare middelen, tijd en ondersteuning voor implementatie. Uma Tori is geslaagd in het mobiliseren van vrouwengroepen van Antilliaanse en Surinaame afkomst in Nederland. De onderzoeksresultaten laten korte termijn veranderingen zien op het niveau van cognities, intentie tot veilig vrijen en seksuele communicatie, wat uiteindelijk kan bijdragen aan hun seksuele gezondheid. De verschillen in implementatie en effecten tussen de drie steden, suggereren dat de effecten samenhangen met de kwaliteit van implementatie. Om effectiviteit te waarborgen is het daarom raadzaam om al bij de interventieontwikkeling veel tijd te besteden aan bevorderen van participatie van alle betrokken partijen en een goede implementatie op grotere schaal.

When people underestimate a risk, often probability information is communicated because of the implicit assumption that it will raise people's risk estimates as a result of these objective facts. Also, scientific literature suggested that stressing the cumulative aspects of a risk might lead to higher susceptibility perceptions than only emphasizing the single incident probability. Empirical evidence that supports the effectiveness of these strategies, however, is lacking. In two studies, we examined whether cumulative and single incident probability information on sexually transmitted infections leads to higher perceived susceptibility for Chlamydia and HIV. Contrary to assumptions and recommendations, results showed that both types of probability information may result in people feeling less susceptible toward Chlamydia and having less intention to reduce the risk. For HIV, no effects were found. These results contradict implicit assumptions and explicit recommendations concerning the effects of probability information on risk perceptions.

The digital therapy intervention for smoking cessation, ‘Happy Ending’, has been shown to be efficacious in two previous randomised controlled trials. The aim of the current article is to disentangle the rationale of the intervention and describe its development. For this purpose, Intervention Mapping is used as a descriptive tool. The intervention is fully automated and delivered by means of the Internet and mobile phones. It is based on self-regulation theory, social cognitive theory, cognitive–behaviour therapy, motivational interviewing and relapse prevention. The ordering of the content is based on a reasoned chronology, modelled according to psychological processes that people experience at certain time points in a process of therapy-supported self-regulation. The design of the intervention is innovative in that it combines four media channels (SMS, IVR, e-mail, and web), and in the combination of just-in-time therapy and a tunnelling strategy based on the natural chronology of quitting. The two forms of just-in-time therapy are a craving helpline (mainly targeting negative affect), and the provision of relapse therapy based on a daily assessment of the target behaviour. The present article meets the recent calls for more thorough descriptions of interventions, and may inform systematic reviews and the development of interventions.

Objective: A sustainable, evidence-based intervention to motivate current blood donors to recruit new donors was evaluated using a quasi-experimental, in-service trial at three donation centers. Design: Participating blood donors in three conditions (N = 734), received (1) an evidence-based leaflet designed to enhance recruitment motivation and five postcards facilitating recruitment and donor registration, (2) five postcards alone, or (3) no materials. Main Outcome Measures: Self-reported donor recruitment by donors was measured at 1-week and 6-week follow-up. Results: At 1-week and at 6-week follow-up, donors in both intervention conditions reported talking to more people about donation and asking more people to donate than control participants. Intervention participants also reported persuading more people to register as a donor than control participants. Results indicated that postcards plus leaflet was somewhat more effective than the postcards alone. Donors’ intentions to recruit at 1-week follow-up mediated the behavioral effects at 6-week follow-up. Conclusion: Motivating and facilitating recruitment of new blood donors through existing donors has the potential to continually replenish the donor population. Keywords: blood donor recruitment, behavior change, intention, cues to action, intervention mapping

The simulation heuristic of Kahnemann and Tversky (1982) suggests that the subjective ease by which a risky situation can be mentally construed, positively influences the person's perceived susceptibility to the presented threat. Assuming that a detailed outline of how a risky event can end up negatively increases the ease of imagination, we tested the hypothesis that scenario-based risk information enhances perceived susceptibility towards contracting a sexually transmitted infection (STI). In an experimental design, undergraduate students were exposed to one or two risk scenario messages or no scenario message (control). The results confirmed the hypothesis, but only when more than one risk scenario message was provided. This adds to the evidence that presenting scenario-based messages could be a feasible method to influence risk perceptions.

Objective: This study describes the effectiveness of 'Uma Tori', an STI/HIV-prevention intervention for women of Afro-Surinamese and Dutch Antillean descent in the Netherlands, aimed at increasing awareness of sexual risk and power in relationships and improving sexual decision-making skills. Methods: Intervention effects were evaluated in a pre-post-test design, using self-report questionnaires among a sample of 273 women. Data were analysed using intention-to-treat, MANOVA with repeated measures and Bonferroni correction for multiple comparisons. Additionally, a qualitative process evaluation, using logbooks and interviews, was conducted to assess fidelity and completeness of intervention implementation. Results: The results showed positive effects on participants' knowledge, risk perceptions, perceived norms and sexual assertiveness. In addition, after the programme, participants had stronger intentions to negotiate and practice safe sex. Furthermore participants communicated more with their partners about safe sex. Conclusion: The effects of 'Uma Tori' are promising and the intervention seems to support attempts to reduce sexual-risk behaviour among Afro-Caribbean women. Practice implication: The evaluation of the programme suggests that this interactive, multiple session, multi-faceted small-group intervention is successful in increasing participants' awareness, sexual assertiveness, intentions to negotiate safe sex, and communication about sexual behaviour with partners. This programme is applicable in practice, provided that it is gender specific and culturally appropriate. © 2008 Elsevier Ireland Ltd. All rights reserved.

Health risk judgments are not merely based on risk statistics but also on the ease with which hypothetical events are imagined. We explored the effects of scenario information as opposed to frequency information on susceptibility perceptions regarding Chlamydia and HIV. Results showed that participants felt more susceptible to Chlamydia after reading frequency information. Scenario information only seemed to affect feelings of susceptibility in participants with no intimate relationship. No effects on perceived susceptibility for HIV were found. Results are discussed in terms of severity of the disease and defensive reactions.

Aims: Effective sexuality and HIV/AIDS education programmes are needed to protect young people against HIV/AIDS and teenage pregnancy in Tanzania and other Sub-Saharan African countries. Using a theory- and evidence-based approach and adapting the programmes to local contexts, increases the effectiveness of these programmes. This paper describes and discusses the challenges and opportunities concerning the application of Intervention Mapping (IM) in the development and implementation of a sexuality and HIV/AIDS education programme targeting young people aged 12—14 in Tanzania. Methods: The sexuality and HIV/AIDS programme was designed in a participatory manner, involving researchers, curriculum developers and teachers' and students' panels. The programme comprised five lessons, organized around 23 sessions with the aim of delaying the onset of sexual intercourse and increase correct and consistent condom use among young people. The programme was delivered by trained teachers as an extracurricular lesson. Conclusions: The IM protocol facilitated the development of a comprehensive sexuality and HIV/AIDS education programme relevant and appropriate to the social cultural context and the needs of learners in Tanzania. The paper has demonstrated that, although the IM was developed in the Western context, it can be used in a flexible manner to adapt to local contexts such as those in Sub-Saharan Africa.

Objective: To explore the smoking cessation process of adolescents and their attitudes and beliefs towards smoking cessation and cessation interventions. Method: Focus group discussions and individual interviews during April-May 2004 with 26 persons aged 15-21 years who all initiated a quit attempt on 1 January 2004. Results: The approach towards all stages of the youth smoking cessation process varied greatly among both successful and unsuccessful quitters. Apart front 'commitment' or the amount of energy put into a cessation attempt, there were no differences in the way successful and unsuccessful quitters approached the quit attempt. 'Smoking friends' and 'Social support' were important for maintaining cessation. Further, participants had negative attitudes towards formalized smoking cessation interventions. Conclusion: There are many approaches to the smoking cessation process. Whether an attempt is successful depends more on individual conditions and the amount of commitment invested in the attempt than on the specific cessation strategy used. Practice Implications: Future adolescent smoking cessation interventions should be flexible regarding both structure and content and should focus on the individual learning process, rather than adhering to rigid cessation strategies.

In many developing countries persons living with HIV and AIDS experience strong stigma and discrimination, and AIDS-related stigma has an enormous negative impact on their social relationships, access to resources, and psychological well being. Moreover, AIDS-related stigma hampers HIV-related health promotion, including voluntary HIV counselling and testing. In this article, we will argue that programs to reduce AIDS-related stigma are most likely to be effective if these programs are based upon thorough needs assessments, theory- and evidence-based intervention strategies and collaborative planning. A protocol for health promotion programs design is outlined. Furthermore, psychosocial correlates of AIDS-related stigma in developing countries, social-psychological theories that might be useful in designing intervention strategies to reduce stigmatisation and successful elements of previous interventions aimed at stigma reduction are discussed. It is concluded that psychological theory does provide guidelines for the development of stigma-reducing intervention programs, but that such programs can only be effective when based upon context-specific needs assessment and collaborative planning.

Objectives. The number of healthy school interventions of unknown quality overwhelms schools. Quality is a construct that is differently interpreted by teachers and health promoters. The schoolBeat checklist for quality assessment of healthy school interventions incorporates the quality perceptions of both professional groups. To support quality improvements – and thus effectiveness – in school health promotion, this study evaluates the schoolBeat checklist. Methods. Twenty-nine healthy school interventions were assessed in the Netherlands, each by two health promoters and two teachers—individually and at a consensus meeting. Generalizability coefficients were calculated for the nine specific quality criteria. Results. The mean consensus score differs from the mean average individual score for two out of nine criteria. To obtain a threshold Generalizability coefficient of 0.70, the number of assessors required per criterion ranges from 1.6 to 10.8, with an average of 4.7. Conclusion. Quality assessment procedures of healthy school interventions using the schoolBeat checklist require about four experienced assessors from each professional domain to facilitate reliable quality scores based on individual assessment only. Publicly available quality scores enable the inclusion of high quality interventions in school policies in order to increase the impact of school health.

To enable improvements in school health promotion, this paper examines associations between the number of health-promotion issues addressed by primary school teachers in the Netherlands and factors thought to influence this behavior. The main factors studied are context characteristics and constructs of attitude, social influence, self-efficacy (SE) and perceived barriers. A total of 180 primary school teachers teaching 9- to 12-year olds (Grades 6, 7 and 8) participated in a cross-sectional survey. The results show that it is possible to differentiate between teachers addressing three or more health issues per year versus those who address fewer based on grade level (more health issues are addressed at higher grades), perceived disadvantages, SE and staff support. The latter seems to exert the greatest influence and may be one of the most promising focus points for improvements of school health promotion in the Netherlands.

A study into the relevance of cultural factors in predicting condom-use intentions among Antillean migrants in the Netherlands is described in this article. The association between the intention to use condoms with a new sexual partner and a perceived taboo on discussing sex, beliefs about sex education and machismo beliefs on gender and power relationships is addressed. The study was conducted among 346 Dutch Antilleans from a random sample of an Antillean population aged 15-50 years. The response rate was 37.8%. The results showed that condom-use intentions were primarily determined by perceived subjective norms, the perceived taboo on discussing sex, machismo attitudes, gender, age and educational background. Moreover, the respondent's opinion regarding machismo was an effect modificator for the association between condom-use intentions and subjective social norm. It is concluded that, in predicting condom-use intentions, factors specific to the culture of a population contribute significantly to the determinants drawn from the general social-cognition models. It is recommended that future research should use measurement instruments that are adapted to culture-specific beliefs, and should explore the influence of cultural factors on actual condom use. Moreover, interventions promoting condom use among migrant populations should target the cultural correlates of condom use. © The Author 2005. Published by Oxford University Press.

Aims: Action to prevent the spread of HIV among young people in Sub-Saharan Africa is needed urgently. In order to be effective, such action should be theory and evidence based and carefully adapted to local cultures and contexts. The present article describes the organization, theoretical basis, and methodological approach of a project that aims at developing and evaluating school-based interventions targeting adolescents aged 12—14 years. Methods: Researchers from European and African universities have developed interventions that were conducted in three sites: Cape Town and Polokwane (South Africa) and Dar es Salaam (Tanzania). In each site the interventions were evaluated through large-scale field experiments with intervention schools and delayed intervention schools and with baseline and two follow-up data collections. Mimimum sample sizes were estimated for each site based on local data and taking into acount that the unit of allocation was schools and not individual students (the design effect). During the formative phase as well as within the field experiments, qualitative studies were also conducted. Discussion: The interventions were developed consistent with the Intervention Mapping approach, and the theoretical framework was based on a modified version of the Theory of Planned Behaviour. The limitations of Western social cognition models were recognized, and the theoretical framework has therefore been expanded in two directions: towards integrating cultural processes and towards taking societal factors and constraints into account. Conclusion: The project will throw light on the application of social cognition models as well as the usefulness of the Intervention Mapping approach to intervention development in sub-Saharan Africa.

Contains fulltext : 55756.pdf (Publisher’s version ) (Closed access) Although the dual function of condom use (preventing pregnancy and preventing STDs) is well known, little is known about the determinants of condom use for STD prevention when contraception is not an issue. We compared two intentions to use condoms with a new sex partner: one based on a vignette not mentioning pregnancy risk and one on a vignette explicitly stating there was no risk of pregnancy. We also investigated whether intentions to use condoms change when there is no pregnancy risk, to allow such changes to be predicted from an STD risk-perception perspective. This cross-sectional survey was completed by 151 undergraduate students. The correlation coefficient between the two intentions about condom use approached zero (0.02; p=.783). Logistic regression showed that two STD risk-perception variables distinguished between consistent and non-consistent reporters of their intention to use condoms. Findings are discussed from the perspectives of policy, methodology and theory. 8 p.

This study investigated the factors influencing whether high school teachers implemented HIV/AIDS education. The independent variables included constructs derived from expectancy value theories, teachers' generic dispositions, their training experience, characteristics of their interactive context and the school climate. We conducted a postal survey of 579 teachers responsible for AIDS education in all 193 public high schools in Cape Town. Questionnaires were completed and returned by 324 teachers (56% response rate) from 125 schools. Many teachers ( 222; 70%) had implemented HIV/AIDS education during 2003, and female teachers were more likely to have implemented than males (74% vs. 58%). The teacher characteristics associated with teaching HIV/AIDS were previous training, self-efficacy, student-centeredness, beliefs about controllability and the outcome of HIV/AIDS education, and their responsibility. The existence of a school HIV/AIDS policy, a climate of equity and fairness, and good school-community relations were the school characteristics associated with teaching HIV/AIDS. These findings demonstrate the value of teacher training and school policy formulation. They also demonstrate the value and importance of interventions that go beyond a sexual health agenda, focussing on broader school development to improve school functioning and school climate.

The aim of this study was to examine the fidelity and completeness of the implementation of a school-based healthful diet promotion programme called 'Krachtvoer' (we use the Dutch title of the programme throughout this article. A possible translation is Power Food, but this does not reflect the play on words in the Dutch title), aimed at lower vocational training students aged 12-14 years. The teachers' and students' opinions of the programme were also assessed, as well as the association between these opinions and the level of implementation. Data were collected through structured teachers' monitoring reports, in-class observations and in-depth interviews with teachers. Further data were drawn from a student questionnaire included in a concurrent cluster-randomized baseline post-test experimental study evaluating the effects of the programme. The present study indicates that the teachers implemented the programme largely according to plan, that the teachers appreciated most parts of the programme and that the students who were exposed to the programme were more appreciative of their nutrition education lessons than students who followed the usual curriculum. However, programme elements that teachers did not like were often not implemented. We conclude that the Krachtvoer programme is a promising tool to encourage students in lower vocational training to adopt diets that are more healthful. The present study revealed the stronger and weaker parts of the programme and can thus guide programme improvement. © The Author 2006. Published by Oxford University Press. All rights reserved.

BACKGROUND: The prevalence of obesity has reached epidemic proportions in many countries and is largely due to behavioral factors that disrupt the energy balance. The purpose of the study was to test how well our conceptual model, combining features from the Theory of Planned Behavior and the Theory of Triadic Influence, explained two behaviors related to the energy balance, namely bicycle use for transportation and snacking behavior in a Dutch adolescent sample.METHODS: Data was gathered in an 1997 cross-sectional sample of adolescents (n = 3,859; mean age 14.8 years SD = 1.6) on snacking behavior, bicycle use, demographics, and potential environmental, cognitive and psychological determinants. Data was analyzed using bivariate correlations, multiple linear and binary logistic regression analyses.RESULTS: Less snacking behavior was associated with female gender and a more positive intention, a more positive attitude, and stronger perceived behavioral control towards restricting snacking. Students who used their bicycle for transportation were more likely to attend secondary education, to be native Dutch, to go to school in a less-urbanized city, to be younger, had a more positive intention and perceived stronger behavioral control and subjective norm towards bicycle use.CONCLUSIONS: The inclusion of environmental factors increased our understanding of bicycle use for transportation and snacking behavior in adolescents. The environmental factors are suggested to be taken into account in interventions aimed at changing these behaviors in more healthy directions.

Health promotion should be evidence-based, needs driven, subject to evaluation, and ecological in perspective. How can this be achieved in the context of school-based sex education? Adopting new behaviors and giving up old habits involves common decision-making, planning, motivational control, and goal prioritization processes. Consequently, despite the particular nature of sexual behavior, models of cognitive change applied to other health-related behaviors also apply to the promotion of safer sex practice. Young people are less likely to have unprotected sexual intercourse if they have acquired a variety of social skills relevant to dealing with romantic and sexual relationships. Many of these social skills and the methods employed to facilitate their development are also important to the promotion of other health behaviors. However, teaching social skills relevant to sexual behavior in classroom settings requires specialist expertise both in program design and in delivery by teachers or facilitators. Theory- and evidence-based programs designed to promote such skills and modified on the basis of effectiveness evaluations are most likely to have an impact on the rate of pregnancies and sexually transmitted infections among young people. Yet, such programs may not be used in schools because of policy and cultural constraints. When this is the case, optimally effective health promotion cannot be delivered. Health promoters should acknowledge these challenges and facilitate the adoption and implementation of effective sexual health promotion programs by targeting communities and legislators.

Intervention mapping: protocol for applying health psychology theory to prevention programmes.Kok G, Schaalma H, Ruiter RA, van Empelen P, Brug J.Maastricht University, The Netherlands. g.kok@psychology.unimaas.nlEvidence-based health promotion programmes are based on empirical data and theory. While a broad range of social and behavioural science theories are available, the actual application of these theories in programme design remains a real challenge for health promotion planners. Intervention Mapping describes a protocol for the development of theory- and evidence-based health promotion programmes. It provides guidelines and tools for the selection of theoretical foundations and underpinnings of health promotion programmes, for the application of theory, and for the translation of theory in actual programme materials and activities. This article presents the protocol and elaborates on the application of theory, using examples from successful intervention programmes.

This article presents the development of a theory- and evidence-based AIDS prevention program targeting Dutch drug users and aimed at promoting condom use. The emphasis is on the development of the program using a five-step intervention development protocol called intervention mapping (IM). Preceding Step 1 of the IM process, an assessment of the HIV problem among drug users was conducted. The product of IM Step 1 was a series of program objectives specifying what drug users should learn in order to use condoms consistently. In Step 2, theoretical methods for influencing the most important determinants were chosen and translated into practical strategies that fit the program objectives. The main strategy chosen was behavioral journalism. In Step 3, leaflets with role-model stories based on authentic interviews with drug users were developed and pilot tested. Finally, the need for cooperation with program users is discussed in IM Steps 4 and 5.

Aims: This is a review of articles on sexual behaviour of school students in sub-Saharan Africa published between 1987 and 1999. The objective was to describe what is known in this regard and identify gaps in knowledge. Methods: Literature search using electronic databases and a thumb search of relevant journals identified 47 articles reporting sexual behaviours of school-based young persons aged between 14 and 24 years. Results: The findings indicate a relatively low number of articles when one considers the scope of the problems related to adolescent sexual behaviour in the region; high prevalence rates of sexual intercourse; infrequent use of condoms and other contraceptives; and significant proportions of adolescents who have two or more lifetime sexual partners. More data are needed on the extent to which adolescents engage in non-penetrative sexual behaviour and penetrative sex other than heterosexual vaginal intercourse; characteristics of the sexual partners of adolescents; and proximal psychosocial antecedents of sexual behaviour and consistent risk-reduction behaviours. Conclusions: Cultural influences on sexual behaviour, the sensitivity of such research in adolescent populations, and the opportunity afforded by school systems for intervention suggest a need for additional exploratory and methodological studies. Placing such information firmly within sociocultural contexts in which young people are raised will better inform effective interventions that both delay the onset of sexual intercourse and encourage use of risk reduction strategies.

Aims: This is a review of articles on sexual behaviour of school students in sub-Saharan Africa published between 1987 and 1999. The objective was to describe what is known in this regard and identify gaps in knowledge. Methods: Literature search using electronic databases and a thumb search of relevant journals identified 47 articles reporting sexual behaviours of school-based young persons aged between 14 and 24 years. Results: The fi ndings indicate a relatively low number of articles when one considers the scope of the problems related to adolescent sexual behaviour in the region; high prevalence rates of sexual intercourse; infrequent use of condoms and other contraceptives; and signifi cant proportions of adolescents who have two or more lifetime sexual partners. More data are needed on the extent to which adolescents engage in non-penetrative sexual behaviour and penetrative sex other than heterosexual vaginal intercourse; characteristics of the sexual partners of adolescents; and proximal psychosocial antecedents of sexual behaviour and consistent risk-reduction behaviours. Conclusions: Cultural infl uences on sexual behaviour, the sensitivity of such research in adolescent populations, and the opportunity afforded by school systems for intervention suggest a need for additional exploratory and methodological studies. Placing such information fi rmly within sociocultural contexts in which young people are raised will better inform effective interventions that both delay the onset of sexual intercourse and encourage use of risk reduction strategies.

This commentary presents a method of working when developing theory-based and data-based intervention programmes to promote health in general as well as the self-regulation of health behaviours. Some of the contributions to this special issue are discussed in the light of this working method. It is concluded that health educators require clear guidelines on how to apply theories, clear definitions of concepts, clear predictions about theoretical relationships, especially in relation to behaviour change, and clear descriptions of the conditions that are necessary for those predictions

In this study, the effects on young adolescent sexual risk behaviour of teacher-led school HIV prevention programmes were examined in two sites in South Africa (Cape Town and Mankweng) and one site in Tanzania (Dar es Salaam). In Cape Town, Dar es Salaam and Mankweng, 26, 24 and 30 schools, respectively, were randomly allocated to intervention or comparison groups. Primary outcomes were delayed sexual debut and condom use among adolescents aged 12-14 years (grade 8 in South Africa and grades 5 and 6 in Tanzania). In total, 5352, 4197 and 2590 students participated at baseline in 2004 in Cape Town, Dar es Salaam and Mankweng, respectively, and 73% (n = 3926), 88% (n = 3693) and 83% (n = 2142) were retained 12-15 months later. At baseline, 13% (n = 224), 5% (n = 100) and 17% (n = 164) had had their sexual debut, and 44% (n = 122), 20% (n = 17) and 37% (n = 57) of these used a condom at last sex, respectively. In Dar es Salaam, students in the intervention were less likely to have their sexual debut during the study (OR 0.65, 95% CI 0.48-0.87). In Cape Town and Mankweng, the intervention had no impact. The current interventions were effective at delaying sexual debut in Dar es Salaam but not in South Africa, where they need to be supplemented with programmes to change the environment in which adolescents make decisions about sexual behaviour.

This study evaluated the effects of an AIDS/STD curriculum for 9th- and 10th-grade students in the Netherlands. Curriculum development was based on (1) theory-based need assessments among students and teachers, (2) pilot testing of data-based and theory-based methods and materials, and (3) cooperation between researchers and students, teachers, and gatekeepers within the school system. Using a quasi-experimental design, program effects on students' attitudes, beliefs, and sexual behavior were compared with those of current AIDS/STD education practice. The results indicated that the experimental curriculum had a stronger favorable impact on students' attitudes and beliefs regarding using condoms consistently. Regarding sexual risk behavior, a differential curriculum effect could be demonstrated. These findings support the contention that current AIDS/STD education can be improved by (1) using empirical data, (2) applying multiple theories from the social sciences, and (3) involving representatives within the school system in the development process.

Background Non-adherence to HIV-treatment can have a negative impact on patients’ treatment success rates, quality of life, infectiousness, and life expectancy. Few adherence interventions have shown positive effects on adherence and/or virologic outcomes. The theory- and evidence-based Adherence Improving self-Management Strategy (AIMS) is an intervention that has been demonstrated to improve adherence and viral suppression rates in a randomised controlled trial. However, evidence of its cost-effectiveness is lacking. Following a recent review suggesting that cost-effectiveness evaluations of adherence interventions for chronic diseases are rare, and that the methodology of such evaluations is poorly described in the literature, this manuscript presents the study protocol for a multi-centre trial evaluating the effectiveness and cost-effectiveness of AIMS among a heterogeneous sample of patients. Methods/design The study uses a multi-centre randomised controlled trial design to compare the AIMS intervention to usual care from a societal perspective. Embedded in this RCT is a trial-based and model-based economic evaluation. A planned number of 230 HIV-infected patients are randomised to receive either AIMS or usual care. The relevant outcomes include changes in adherence, plasma viral load, quality of life, and societal costs. The time horizon for the trial-based economic evaluation is 12–15 months. Costs and effects are extrapolated to a lifetime horizon for the model-based economic evaluation. Discussion The present multicentre RCT is designed to provide sound methodological evidence regarding the effectiveness and cost-effectiveness of a nurse-based counselling intervention (AIMS) to support treatment adherence among a large and heterogeneous sample of HIV-infected patients in the Netherlands. The objective of the current paper is to describe the trial protocol in sufficient detail to allow full evaluation of the quality of the study design. It is anticipated that, if proven cost-effective, AIMS can contribute to improved evidence-based counselling guidelines for HIV-nurses and other health care professionals. Trial registration The study has been registered on clinicaltrials.gov (Identifier: NCT01429142).

This study reports data from a sample of 698 Dutch secondary school teachers intending to provide classroom AIDS education. The study addresses determinants of awareness knowledge about and adoption of four nationally disseminated AIDS curricula. The results indicated that knowledge acquisition was largely dependent on diffusion networks within schools. Transition from awareness knowledge to adoption appeared to be mediated by perceived instrumentality, subjective norms, perceived colleague behavior, and teachers' sexual morality. Preferences for using one curriculum rather than another were related to the same variables, although financial costs became slightly more important. It is concluded that effective dissemination strategies should combine (1) development of validated materials with clear instruction for implementation, (2) focused mass media communication. (3) close collaboration of curriculum designers, linking agents, and teachers, and (4) access to in-person assistance.

Item does not contain fulltext HIV-related stigma in African and Afro-Caribbean diaspora communities in the Netherlands was investigated. Interviews with HIV-positive and HIV-negative community members demonstrated that HIV-related stigma manifests as social distance, physical distance, words and silence. The psychological consequences of HIV-related stigma among those diagnosed with HIV reported were emotional pain, sadness, loneliness, anger, frustration and internalised stigma. The social consequences included decreased social network size, limited social support and social isolation, and resulted from not only enacted stigma but also self-imposed social withdrawal. Also, poor treatment adherence was a health-related consequence. People living with HIV employed both problem-focused and emotion-focused coping strategies to mitigate the negative consequences of stigma. Problem-focused coping strategies included selective disclosure, disengagement, affiliating with similar others, seeking social support and, to a lesser extent, activism. Emotion-focused strategies included distraction, positive reappraisal, religious coping, external attributions, disidentification and acceptance. HIV-related stigma clearly permeates African and Afro-Caribbean communities in the Netherlands, and should be targeted for intervention.

This article addresses the issue of stigmatization and discrimination towards people with AIDS (PWAs) using Weiner's attributional theory of motivation and emotion. In a field experiment, subjects responded to vignettes describing patients with AIDS, syphilis, lung cancer or tuberculosis. In these vignettes, the onset of the diseases was either described as personally controllable or as uncontrollable. Results show that although attributional variables do account for a significant amount of variance in helping behavior and emotions towards PWAs, other variables such as the incurability of the disease, the risk of infection and associations with (homo)sexuality, may be more useful in explaining reactions to PWAs. Implications for education tailored at the prevention of the stigmatization of PWAs are discussed.

This paper describes the results of a cross-sectional survey of 956 Dutch secondary school teachers. It explores the determinants of adoption of classroom-based AIDS education. The results showed that teachers decision making was most strongly related to highly specific adoption-related beliefs (outcome beliefs subjective norms self-efficacy). Adoption was additionally related to more generic dispositions (sense of responsibility and sexual morality) and environmental conditions (school policy and frequency of collegial interaction about HIV instruction). Past experience with AIDS education appeared to be positively associated with teachers intentions and related determinants. It is concluded that additional support needs to address teachers anticipated ideological and practical constraints both by mass media interventions and responsive in-person assistance. (authors)

This study investigated the possibility of rerecruiting lapsed blood donors. Reasons for donation cessation, motivation to restart donation, and modifiable components of donation motivation were examined. We distinguished between lapsed donors who had passively withdrawn by merely not responding to donation invitations and donors who had contacted the blood bank to actively withdraw.A cross-sectional survey was sent to 400 actively lapsed donors and to 400 passively lapsed donors, measuring intention to restart donation and psychological correlates of restart intention. The data were analyzed using multiple regression analyses.The response rate among actively lapsed donors was higher than among passively lapsed donors (37% vs. 25%). Actively lapsed donors typically ceased donating because of physical reactions, while passively lapsed donors quit because of a busy lifestyle. Nonetheless, 51% of actively lapsed responders and 80% of passively lapsed responders were willing to restart donations. Multiple regression analysis showed that, for passively lapsed donors, cognitive attitude was the strongest correlate of intention to donate in the future (β=0.605, p0.001), with affective attitude (β=0.239, p0.05) and self-efficacy (β=0.266, p0.001) explaining useful proportions of the variance as well. For actively lapsed donors, cognitive attitude was also the strongest correlate of intention (β=0.601, p0.001), with affective attitude (β=0.345, p0.001) and moral norm (β=-0.118, p0.05) explaining smaller proportions of the variance.The majority of lapsed donors indicated a moderate to high intention to restart donations. Interventions focusing on boosting cognitive and affective attitudes and self-efficacy could further raise such intentions.

Concurrent partnerships have been recognized as a determinant for the spread of HIV and sexually transmitted infections (STIs). We studied the association of concurrent partnerships with sexual behaviour among heterosexual Caribbean and African migrants, who account for a disproportionate burden of STIs and HIV in the Netherlands. Of 1792 migrants, 15% reported concurrent sexual partners in the previous six months. In multivariate multinomial analyses, women were less likely to have concurrent partners than men and they were less likely than men to use condoms with concurrent partners. We could not identify an association with the observed HIV prevalence; however, migrants with concurrent partners were less likely to be tested for HIV. Of migrants tested for STIs, one in three migrants with concurrent partners was diagnosed with an STI. Prevention targeting migrants should address the promotion of HIV/STI testing and stress the potential acceleration of HIV and STI epidemics due to concurrency.

Background This paper evaluates the effect of the World Starts With Me (WSWM), a comprehensive sex education programme in secondary schools in Uganda. The aim of the present study was to assess the effects of WSWM on socio-cognitive determinants of safe sex behaviour (delay; condom use and non-coercive sex). Methods A survey was conducted both before and immediately after the intervention among students in intervention (N = 853) and comparison (N = 1011) groups. A mixed model repeated measures analysis was performed to assess the effectiveness of the WSWM programme on the main socio-cognitive determinants of safe sex behaviour at post-test. A similar post-hoc comparison was made between schools based on completeness and fidelity of implementation of WSWM. Results Significant positive effects of WSMW were found on beliefs regarding what could or could not prevent pregnancy, the perceived social norm towards delaying sexual intercourse, and the intention to delay sexual intercourse. Furthermore, significant positive effects of WSWM were found on attitudes, self-efficacy and intention towards condom use and on self-efficacy in dealing with sexual violence (pressure and force for unwanted sex). A reversed effect of intervention was found on knowledge scores relating to non-causes of HIV (petting, fondling and deep kissing). A follow-up comparison between intervention schools based on completeness of the programme implementation revealed that almost all significant positive effects disappeared for those schools that only implemented up to 7 out of 14 lessons. Another follow-up analysis on the basis of implementation fidelity showed that schools with a "partial" fidelity score yielded more significant positive effects than schools with a "full" fidelity of implementation score. Conclusions The study showed an intervention effect on a number of socio-cognitive determinants. However, the effectiveness of WSWM could be improved by giving more systematic attention to the context in which such a programme is to be implemented. Implications for the systematic development and implementation of school-based safe sex interventions in Uganda will be discussed.

The efficacy of a tailored, web-based intervention communicating the risks of sexually transmitted infections (STI) for heterosexual young adults was examined in a randomised, controlled trial. The main aims of the relationship-oriented intervention were to influence risk perceptions and to promote (maintenance of) condom use and STI-testing among young adults who reported being recently engaged in a heterosexual relationship. The intervention addressed risk perceptions, attitudes, normative beliefs, self-efficacy and skills related to condom use and STI-testing. Outcomes were compared immediately after the intervention (N = 171) and 3 months later (N = 115) to a non-tailored intervention group and to a control group. Cognitive and behavioural outcomes showed that the tailored intervention was efficacious in influencing perceived susceptibility to STI and STI-testing intentions immediately after the intervention, and in reducing rates of unprotected sex at 3 months.

Item does not contain fulltext HIV status disclosure is often characterized as a dilemma. On the one hand, disclosure can promote health, social support, and psychological well-being. On the other, disclosure can lead to stigmatization, rejection, and other negative social interactions. Previous research has shown that HIV status disclosure is a reasoned process whereby the costs and benefits to oneself and to others are weighed. As such, understanding disclosure requires understanding the reasons for and against disclosure employed by people living with HIV (PLWH). In this study, disclosure among a population disproportionately affected by HIV in the Netherlands, namely African and Afro-Caribbean diaspora, was investigated. Reasons for nondisclosure were fear of stigmatization, previous negative experiences with disclosure, having observed the stigmatization of other PLWH, shame, the desire to protect others – particularly one's children and family – from stigmatization by association and/or worrying, and the belief that one's HIV status is a private matter. Participants reported disclosing because they were in a close and supportive relationship, disclosure led to emotional release, disclosure could lead to emotional or financial support, they felt a perceived duty to inform, and they had a desire to educate others about sexual risk-taking. The findings suggest that stigma plays an important role in disclosure decisions among these populations. They further point to a need for HIV-related stigma reduction interventions in African and Afro-Caribbean communities and culturally sensitive counseling for PLWH whereby caregivers do not automatically assume that disclosure is best but rather provide a safe environment in which the costs and benefits of disclosure can be weighed and strategies for disclosure can be developed, if perceived as beneficial by PLWH. 11 p.

AIDS education emphasizing personal responsibility toward AIDS-inducing behavior might enhance negative reactions to people with AIDS. This study, based on Weiner's attributional theory of motivation and emotion, addressed this dilemma by reporting data from a sample of 1,018 Dutch secondary school students. Results support the reasoning that emphasizing personal responsibility, and consequently personal controllability, increases negative reactions to people with AIDS. In addition to causal attributions, however, AIDS knowledge and attitudes toward homosexuality also related significantly to reactions to people with AIDS. To prevent negative reactions to people with AIDS, the subject of homosexuality should be dealt with before AIDS education is provided. AIDS education should address the impossibility of HIV infection by daily interactions, and the meaning and consequences of being seropositive.

The determinants of consistent condom use were investigated in a cross-sectional study of 1018 students 12-19 years of age from 18 Dutch secondary schools. The study was prompted by concern over the lack of acceptance of condoms on the part of young people in The Netherlands despite extensive acquired immunodeficiency syndrome (AIDS) prevention campaigns. Components of the variance in behavioral intention to use condoms included intuitive attitude regarding personal consequences 34%; self-efficacy (degree to which students considered themselves able to obtain and negotiate condom use) 12%; subjective social norms derived from parents peers and sexual partners 3%; perceived vulnerability to AIDS 2%; and perceived beliefs and behaviors of peer 2%. Adolescents with significant sexual experience (intercourse more than 5 times) were less likely than their inexperienced counterparts to respond positively to condom use as a means of avoiding transmission of AIDS. Students with extensive sexual experience were less likely to express discomfort with the idea of raising the subject of condom use with a new partner than their inexperienced peers but were likely to anticipate problems with consistent condom use with a well-known sexual partner. Those who reported consistent condom use also expressed confidence in their ability to use condoms even when drunk and to interrupt lovemaking to apply a condom. In addition consistent users were less likely to focus on the unpleasant aspects of condom use (decreased sexual stimulation messiness) and to perceive a positive social norm regarding this method of AIDS prevention. Given the finding that condoms decline in popularity as adolescents gain sexual experience behavioral skills programs that increase confidence in purchasing condoms and negotiating their use with sex partners should be implemented.
