Final answer:
The true statement about contraceptive use in adolescence is that adolescents who have good relationships with their parents are more likely to use birth control. Parental influence and comprehensive sexual education significantly impact adolescents' contraceptive behaviors.
Step-by-step explanation:
The subject of the question revolves around the use of contraceptives among adolescents and the factors influencing their usage. Statements about adolescent contraceptive use show that good relationships with parents are likely to increase the likelihood of birth control use as teenagers report that parents are a significant influence on their behavior, especially concerning sexual behavior. Moreover, comprehensive sex education, as seen in Germany, correlates with lower rates of teenage pregnancy compared to countries without such programs, highlighting the importance of proper sexual education. The notion that young people tend to use contraception mainly in new relationships where there's high trust or love is countered by the reality that adolescents can struggle with self-regulation and may not always use contraception consistently, despite the intentions they express in surveys about settling down monogamously in the future.
