The Men's Safer Sex (MenSS) Trial: a website to increase condom use

INTERVENTION: Participants will be allocated by computer algorithm to either usual care (the control condition) or usual care plus the interactive digital intervention (intervention condition). Those in the intervention condition will be asked to spend time interacting with the intervention whilst in the clinic waiting room, and will then have access to the intervention for the next 12 months. The intervention is an interactive, theory‐based website to promote condom use in men. Sexual health outcomes (e.g., condom use, STI diagnoses) will be assessed at baseline (before randomisation), and 3, 6, 9, and 12 months later. CONDITION: 1. Sexually transmitted infections 2. Sexual health promotion ; Infections and Infestations PRIMARY OUTCOME: The primary outcome is self‐reported condom use for penetrative sex over the previous three months. This is a small‐scale pilot trial to test the procedures for a future full‐scale trial, so we will also assess the success of recruitment, trial procedures and retention over one year. SECONDARY OUTCOME: Pilot trial:; 1. We will measure outcomes such as knowledge, confidence in ability, and motivation, which contribute to behaviour change (increased condom use). We will also measure self‐reported sexually transmitted infection (STI) and record STI diagnoses from sexual health clinic notes.; 2. Qualitative process evaluation:; 2.1. Men's experiences and views of participating in the pilot trial, and views of the website to increase condom use; 2.2. Sexual health clinic staff members' views of the trial procedures and the role of interactive digital interventions (e.g. websites) in sexual health clinical care ; 3. We will also work out the best methods of data collection and analysis for a cost effectiveness analysis analysis for a future full scale randomised controlled trial INCLUSION CRITERIA: 1. Male 2. Aged 18 years and over (with no upper age limit) 3. Able to read English 4. Heterosexual and sexually active 5. Possession of an active email account and access to the internet 6. Reporting 2 or more sexual partners in the last year, and unprotected sex in the last 3 months 7. Predominantly female partners, or an equal number of male and female partners
