Informing school sex education using the stages of change construct: sexual behaviour and attitudes towards sexual activity and condom use of children aged 13-16 in England.

A survey of 3820 school children in England aged 13-16 years examined sexual activity using the Transtheoretical Model (TTM) Stages of Change. A quarter (26%) of teens were sexually experienced, 44.8 per cent did not use contraception and 48.9 per cent did not use condoms, every time. Past history of condom and contraceptive use, and partner willingness to use condoms were the best predictors of being in Action or Maintenance stage for condom use. Of virgins, 19.82 per cent were in Contemplation or Preparation stages for intercourse, and 85.4 per cent would use condoms every time. Sex education should be tailored to Stage, and signposting to sexual health and contraception services.
