Main Article Content
Purpose: This study aimed to investigate the predictability of knowledge, attitude, subjective norm and perceived behavioral control on intention to the use of long - acting reversible contraception among primipara pregnant adolescents.
Design: Correlation predictive design.
Methods: The sample consisted of 134 adolescent pregnant women receiving antenatal care at tertiary hospital in Phitsanuloke province. Instruments included the demographic characteristic questionnaire, the knowledge about use of long - acting reversible contraception questionnaire, the attitude towards the use of long - acting reversible contraception questionnaire, the subjective norm towards the use of long - acting reversible contraception questionnaire and the perceived behavioral control towards the use of long - acting reversible contraception questionnaire. Data were analyzed using descriptive statistics and Multiple Linear Regression.
Main findings: The finding revealed that knowledge, attitude, subjective norm and perceived behavioral control could explain the variances in intention to the use of long - acting reversible contraception among primipara pregnant adolescents by 19% (R2 = .19). Only Subjective norm could predict intention to use long - acting reversible contraception among primipara pregnant adolescents with statistical significance (β = .30, p < .05).
Conclusion and recommendations: Subjective norm could predict intention to the use of long - acting reversible contraception in primipara pregnant adolescents. Therefore, it is suggested that midwives and nurse should promote the intention by encouraging husbands and family members as the supporters of adolescent pregnant women to plan together with the adolescents for using long - acting reversible contraception.
