Using the behaviour change wheel to examine facilitators and barriers to assertive contraception-use conversations for Indonesian women.

Contraception-use communication between sexual partners is important to reduce unwanted pregnancies and protect sexual and reproductive health. There is a dearth of research focused on developing countries where sexual and reproductive health conversations are often considered taboo. Using the Behaviour Change Wheel, this qualitative study examines the facilitators and barriers to having assertive contraception-use conversations with a male partner for Indonesian women and then identifies behaviour change techniques as potential intervention strategies. Semi-structured interviews were conducted with ten Indonesian women aged 18 to 29 years who had been sexually active and were currently in a committed dating relationship with a male partner. Using thematic analysis, 13 themes were identified. Facilitators of assertive contraception-use communication include knowledge about sexual and reproductive health and contraception, communication skills, closeness of the relationship with one's partner, other people's experiences of sex and contraception, and social media norms concerning the open discussion of sex and contraception. Fear of initiating the conversation about contraception was a barrier. Partner's attitude towards having contraception-use conversations and the taboos surrounding contraception in Indonesian culture acted as both facilitators and barriers. Suggested strategies to promote contraception-use communication include using social media to break the stigma surrounding sexual and reproductive health matters, normalising assertive conversations about contraceptive use with sexual partners, empowering women to be more assertive about their preferences for contraception, and teaching strategies to promote assertive contraception-use communication among young women and men in Indonesia.
