This study aimed to study dual contraceptive intention in female junior high school students in Chonburi province and to determine factors predicting dual contraceptive intention in female junior high school students in Chonburi province. The participants were 407 female lower secondary students in lower secondary school years 2 and 3 in Chonburi Province. The samples were recruited for the survey using multi-stage random sampling. The data was collected using online self-answer questionnaires. (equestionnaire) consists of: Demographic data, attitude toward sexual behavior, knowledge of birth control, Ease of sexual communication with parents, attitudes toward dual contraception, Subjective norms of dual contraceptive, selfefficacy of dual-contraceptive and dual-contraceptive intentions of adolescent girls. Their KR-20 = 0.73 and Cronbachs alpha coefficients were 0.84, 0.95,0.88, 0.89, 0.86 and 0.87 respectively. Data were analyzed by using Stepwise multiple regression analysis. The results revealed that 68.8% of female lower secondary school students had a high level of intention to use dual methods of contraception (M = 26.35, SD = 4.19). Factors predicting dual contraceptive intention were: attitude towards dual contraception (β = -.292, p< .001), self-efficacy in dual contraception (β = .239,p < .001), educational achievement (β = .178, p< .001) and convenience of sexual communication with parents (β = .116, p = .007 ). These significant predictive variables accounted for 28.8 % of the total variance in the dual methods of predicting contraceptive intentions (R 2 adj =.281, p= .007). The results of this study suggest that school health nurses strengthen their belief in positive attitudes towards dual contraception. encouraging adolescents to use two methods of contraception is to create a variety of options to make it easier for teens and to access dual birth control services.
