Father involvement in the childbearing period is important for maternal and child health. The patriarchal culture adopted by most tribes in the city of Kupang contributes to the role of fathers in the childbearing period. This study aims to identify the relationship between paternal self efficacy and father involvement in the childbearing period in people with pariakhi culture. This study used a cross sectional approach with cluster random sampling on 150 patriarchal fathers in the Oepoi and Pasir Panjang health centers in Kupang, East Nusa Tenggara, Indonesia. The questionnaire used is the General Self Efficacy questionnaire and the questionnaire Father`s Involvement in Pregnancy and Childbirth Questionnaire (FIPCQ). The results showed that there was a significant relationship between paternal self efficacy and father involvement (p value = 0.006). Fathers with high paternal self efficacy are 2.7 times more likely to be involved in the childbearing period. The variable father`s attitude and information support moderates the relationship between paternal self efficacy and father involvement. The husband`s standby program through the Kupang city government policy needs to be strengthened.
