Abstract

This predictive research aimed to study the level of intention to use long-acting reversible contraception (LARC) and factors affecting the intention to use LARC among pregnant adolescents in Chiang Rai Province. The sample consisted of 116 pregnant adolescents receiving antenatal care. Participants were selected through convenience sampling. The research instruments included questionnaire 1) personal data, 2) intention to use LARC, 3) attitudes toward LARC, 4) subjective norms regarding LARC, 5) perceived behavioral control of LARC, and 6) fear of LARC side effects. The content validity index (CVI) was 1.00 and reliability coefficients of .93, .82, .94, .80, and .85, respectively. Data were analyzed by using descriptive statistics and multiple regression analysis.
The findings revealed that the sample had moderate levels of intention to use LARC (M = 53.02, SD = 25.85). The factors that significantly affected the intention to use LARC included: subjective norms regarding LARC (β = .428, p < .001) and perceived behavioral control of LARC (β = .218, P < .05). All factors together explained 14.4% of the variance in intention to use LARC (Adjusted R2 = .144, F(5, 110) = 4.858, p < .001). Recommended to develop programs that enhance perceived behavioral control of contraception, with the involvement of mothers and husbands, to promote the intention to use LARC.
