Plain English Summary

Background and study aims
Poor sexual health is not shared equally across the UK population. The Department of Health has identified the need to reduce sexually transmitted infection (STI) rates as a priority for reducing SH inequalities and have recognised men who have sex with men and young people as target ‘at-risk’ groups. The health, social, and economic costs of STIs are huge. The current cost of STI treatment to the NHS is £620 million per year. Recent guidelines from the National Institute for Health and Care Excellence include the need to teach young people to use condoms effectively and safely before providing them.
Condoms remain the main protection against STIs when used correctly and consistently, yet there are many barriers to their use such as reduced sexual pleasure, fit-and-feel problems, lubrication issues and erection difficulties. Many health promotion programmes try to improve knowledge and skills to increase condom use, but do not address the barriers. There is a need to develop effective programmes to reduce barriers and improve condom use experiences to help reduce sexual risk among young people. Furthermore, given the increasing use of the internet by young people, designing programmes using digital technology is seen as a key delivery strategy.
Researchers have developed a condom promotion programme for use among young men in the UK. The programme gives out condom kits (containing different types of condoms and lubricants) and asks men to experiment with the contents at home by themselves following condom use education and training. The education and training can either be delivered online (eHIS) or face-to-face by a health professional (proHIS). As men test each condom and lubricant they are asked to think about their own pleasure and which they like. An online rating exercise helps men to identify the ‘best’ condoms and lubricants for them. Men who have already tested the programme said that they have enjoyed it and would recommend it to others.
The aim of this study is to find out whether men who experiment with different types of condoms report more enjoyable, correct and consistent condom use, and are less likely to have chlamydia at follow-up than men who do not. The researchers also want to find out if it is more effective, acceptable and cost effective to deliver the programme face-to-face or online.

Who can participate?
Men aged between 16-25 years who are at risk of STIs because they do not use condoms during sex with casual and/or new partners

What does the study involve?
Young men will be recruited via adverts on social media, from young people’s information and advice services, and from specialist sexual health services at selected sites across England. Men will be assigned at random to receive either the digital eHIS programme, the face-to-face proHIS programme or usual condom care and will be followed up for 12 months during which they will be asked at various times about their sexual behaviour, condom use experiences and to take Chlamydia tests, to see if Chlamydia rates and/or condom use behaviours differ between the groups of young men.

What are the possible benefits and risks of participating?
The researchers will share the findings widely to improve the health and wellbeing of young people through reducing risk to STIs. Engagement of health professionals and policy makers will support adoption of the programme into mainstream practice and help reduce public health and NHS costs. The potential benefits to participants will include:
1. Gaining knowledge regarding the many different types (sizes, shapes and textures) of condoms that are on the market
2. The opportunity to experience a broad range of lubricants
3. Gaining knowledge and skills to increase the enjoyment of condom use
4. Finding the 'best' condom for them (fit and feel)
5. Improved condom use satisfaction
6. Reduced risk of STIs
There is a small but potential risk that a young man registers for the study and is not aware that they have a latex allergy. Symptoms of latex allergy occur immediately, but some people have a delayed reaction which is more likely to be an itchy rash. Following an eligibility check participants who report that they are “unsure” if they have a latex allergy will be highlighted (via the web-based software platform Lifeguide) to the study site staff who will then further question the participant to determine level of risk. Men who report previous symptoms will be excluded from the trial. Those deemed to be at low risk with no previous allergen history will be allowed to continue but instructed to cease use of all condom products and to contact the site immediately if they experience any adverse reactions. Some participants may view having to complete routine sexual health questionnaires and being contacted by researchers (e.g. to remind participants to complete online forms) as an inconvenience. To compensate for the burden and intrusion imposed by the research all participants will receive voucher payments totalling £50 spread over the 12 month study period. As this study involves young people and is on a sensitive topic, the information sheet provided to prospective participants will highlight the risk of embarrassment/distress. Participants will be provided with a list of contacts in the information sheet if they require further support either during or after the study.

Sexually transmitted infections


On submission of baseline questionnaire data, participants are randomised by way of a computer algorithm within each recruitment setting, with stratification by ethnicity and sexual orientation. Participants will be allocated to one of the three trial arms at a ratio of 1:1:1.

Face-to-Face Delivery: proHIS
Young men allocated to the proHIS intervention arm will receive a brief face-to-face consultation with the trained research nurse (RN) at the registration visit (10 mins), during which each participant will receive:
1. A verbal introduction to HIS-UK
2. A comprehensive condom application demonstration using a penile demonstrator to teach correct condom use competency
3. Information about lubricants, their benefits, and how to use them
4. An overview of the condom information and self-practice instruction guide containing details of the home-based exercises and how to rate the condoms and lubricants tested
5. A condom kit containing a variety of condoms and lubricants
6. Login details to the Lifeguide on-line delivery platform with access to the condom/lubricant rating forms and follow-up questionnaires

Digital Delivery: eHIS
Young men allocated to the eHIS intervention arm will receive the following from the RN:
1. A condom kit containing a variety of condoms and lubricants
2. Login details to the Lifeguide platform with full access rights to the eHIS website, the condom/lubricant rating forms and follow-up questionnaires
Lifeguide is an interactive web-based intervention software platform and secure validated data management system designed to collect participant information and deliver digital interventions (DI) to support health behaviour change. Participants who are allocated to eHIS will be granted access to the eHIS web-pages when logging into Lifeguide. The eHIS pages will remain hidden to all other participants.

Using interactive digital media (information, videos and serious gaming) the eHIS website will provide:
1. An introduction to HIS-UK
2. Teaching on correct condom use
3. Information about lubricants, their benefits, and how to use them
4. Advice on condom self-practice and details of condom use exercises to try out at home
5. Details on how to test and rate the condoms and lubricants provided in the condom kit

Following education and training all young men in the two intervention arms (proHIS and eHIS) then begin a two-week condom/lubricant experimentation and self-practice period using the contents of the condom kits and following the home-based exercises. The aim is for participants to practice applying, using (masturbating with) and removing each of the condoms provided in the condom kit in “low pressure” situations (i.e., not in the presence of a sexual partner) and to try out and experiment with the different lubricants.

After experimentation with each condom/lubricant, participants are requested to complete an online rating and feedback form using the Lifeguide platform. Automated texts and e-mails will prompt intervention arm participants to complete the required ratings. Protocol compliance is defined as a minimum of three submitted rating forms and full compliance as the submission of eight.

Usual care is the comparator control condition. Young men randomly allocated to the control arm receive:
1. Standard condom distribution care offered in the sexual health/GUM recruitment setting
2. Login details to the Lifeguide platform (to complete the follow-up questionnaires)

Intervention type



Drug names

Primary outcome measure

Chlamydia test positivity rate, measured through biomarker testing and treatment at baseline, 6 and 12 months, and through self-reporting at other times. The primary health endpoint will be test positivity rate at 6 months. To examine longevity of intervention effect, test positivity will be assessed up until 12 months post randomisation

Secondary outcome measures

To assess the effectiveness of HIS-UK to improve correct and consistent condom use as compared to usual condom distribution care, the following validated online questionnaires obtained at baseline (T0), and at monthly intervals to 12 months (T1-T12) will be used:
1. Condom Barriers Scale
2. Condom Use Errors and Problems Survey
3. Condom Use Self-Efficacy Scale
4. Multidimensional Condom Attitude Scale
5. Sexual behaviour and contraceptive use survey (sexual partner history, relationship status/type, frequency of intercourse, use of contraception/condoms)
6. Health-related quality of life indicators (SF-12 and EQ5D-5L)

Results and Publications

Publication and dissemination plan

The research will generate important outputs for dissemination, including:
1. An evidence-based digital condom promotion intervention tailored for young men
2. Manual and best practice protocol for delivering the intervention in face-to-face contexts
3. Estimates of costs of the intervention
4. Stakeholder database for future research and implementation
5. Scientific report for funders and lay summary report
6. Conference presentations and peer-reviewed articles

All descriptions or documentation of the intervention (e.g., in write-ups, reports) will be informed by the TIDieR framework. The researchers will set up a university-based project website and Facebook page to disseminate research updates, working papers/reports, links to online resources, media-friendly summaries, key findings, and recommendations. Updates will be posted on Twitter and other social networking sites which link to these websites. The study will have an online discussion forum to invite and encourage discussion among all of the stakeholders. Relevant social networking sites (Facebook, Twitter etc.) will be created for user group communication activities. The researchers will also establish early channels of communication with NICE and PHE to ensure that their findings feedback into any future recommendations.

The researchers will disseminate findings through the PHE sexual health facilitators (SHF). One SHF is based in each of the PHE centres and works closely with local authority (LA) sexual health commissioners through regional networks and individual support. The researchers will present findings and recommendations at a meeting of the English Sexual Health and HIV Commissioners Group. Funded by PHE, this group brings together commissioners from all LAs, through four meetings per year and also has a website for sharing information. The researchers will ensure findings are shared with NICE to inform any future revision of the NICE Guideline (NG68; Sexually transmitted infections: Condom distribution schemes, which includes recommendations for LAs). They will host a dissemination event to bring together stakeholders and end-users and provide an open forum for the research to be discussed, for stakeholders to provide fresh perspectives, to encourage positive exchange, and to facilitate impact. A lay executive summary will be distributed to all identified stakeholders and to all those who participated in the research activities and they will be encouraged to further distribute to interested parties. The University media relations offices will issue press releases about the study via local/national media and the public engagement units will enhance the profile of this work in the public domain. The researchers shall work with the Teenage Pregnancy Knowledge Exchange to share our findings which has a database of all teenage pregnancy leads in Local Authorities and the FSRH sexual health and HIV e-bulletin which reaches large numbers of commissioners. Findings will also be disseminated to the academic and healthcare community through the more traditional academic routes of conference presentations (e.g., Sexual Health Advisors National Conference, British Association for Sexual Health and HIV) and peer-reviewed, open-access journal articles.

IPD sharing statement
