Abstract

Repeat pregnancy among adolescents is a major problem which affects maternal health, families, and the country. It has been found that the occurrence of repeat pregnancies among adolescents was higher in lower Southern Thailand than in any other region. This cross-sectional study aimed to examine the level of intention to use contraceptive implants and factors influencing the intention to use contraceptive implants among pregnant adolescents. The participants were 319 pregnant adolescents attending antenatal clinics in three secondary care hospitals and one tertiary care hospital in lower southern Thailand. Data were collected using eight questionnaires that dealt with personal information, attitudes toward contraceptive implants, subjective norms relating to contraceptive implants, perceived behavioral control concerning contraceptive implants, knowledge of contraceptive implants, life goal settings, fear of side effects of contraceptive implants, and intention to use contraceptive implants. There were validated by 3 experts and examined using Cronbach’s alpha coefficient in questionnaire 2, 3, 4, 6, 7, 8, yielding values of .71, .83, .75, .94, 87, .89. The reliability of questionnaire 5 was tested using Kuder-Richardson 20 (KR-20) yielding a value of .72. Data were analyzed using descriptive statistics, Pearson’s correlation test, and simultaneous multiple regression analysis. The result showed that intention to use contraceptive implants was moderate among pregnant adolescents in lower Southern Thailand. Perceived behavioral control toward contraceptive implants was the strongest predictor overall and together with attitude toward contraceptive implants and subjective norm toward contraceptive implants, significantly explained 34.4% of the variance in intention to use contraceptive implants. The results of this study could serve as a basis for developing care programmes to promote intention to use contraceptive implants among pregnant adolescents in lower Southern Thailand.
