The effectiveness of a tailored programme to promote reproductive-health-promoting behaviour in young women based on the Precaution Adoption Process Model: A randomized controlled trial.

Only 59 participants were analysed, with 8 and 5 in intervention Stages 2 and 3 and 7 and 4 in control Stages 2 and 3, so findings for Stages 2 and 3 are limited. The programme bundled seminars, periodic messages, Q&A, practical training, tailored information, videos and counselling, so the contribution of any single component cannot be separated. Participants and data analysts were not blinded, and all outcomes were self-reported online questionnaires. Follow-up was only 8 weeks, so long-term behaviour and persistence were not tested. The analysis included 30 intervention and 29 control participants, not all 60 assigned. Contraception use was measured over a short period and may not reflect actual behaviour. Recruitment was through convenience sampling from university notice boards in Seoul. Mean age differed slightly between groups at baseline (23.00 versus 22.03 years). The control group received educational material once.

The study was supported by the Health Fellowship Foundation in Korea, and the funding source was not involved in the research or article preparation. The authors declare no potential conflicts of interest.

Do not conclude that this programme increases contraception use. The rate of contraception use did not differ significantly between groups (Z = -0.47, p = .641), and the significant finding was for self-reported reproductive-health-promoting behaviour, not confirmed contraceptive behaviour.
