Key outcomes are the quality of intervention implementation and recruitment and retention of participants. The study
will also pilot the feasibility and acceptability to participants of providing demographic data and answering sexual behaviour
questions measuring the proposed primary and secondary outcomes for a future, larger phase III trial. Drawing upon the
United Kingdom Medical Research Council Guidelines (MRC, 2008), a phase III study is a randomised controlled trial in which
the sample size is statistically powered to capture the effectiveness of an intervention.
