Silver Ring Thing is a virginity pledge program which encourages teens and young adults to remain sexually abstinent until marriage. It is based in the United States and was until 2005 partially funded by the U.S. federal government. Drawing on Christian theology, SRT uses rock/hip hop concert-style events in an attempt to appeal to 21st-century teenagers.
SRT events feature high-energy music, club-style lighting and sound, music videos, sketch comedy, and a Christian abstinence message. During the gathering, participants commit to a vow of sexual abstinence until marriage by purchasing rings.
Shortly before the end of the event, they receive their silver rings inscribed with Bible verses, which are usually worn on the ring finger of the left hand. The verse is , "For this is the will of God, even your sanctification, that ye should abstain from fornication. That every one of you should know how to possess his vessel in sanctification and honour". The rings are tokens of their vow, a reminder of their decision to remain celibate. The rings also are a way to signal to others that they are pledged to celibacy. After they put on their rings, they take a vow to remain abstinent.
Some studies of the efficacy of virginity pledges have found they may be effective in delaying vaginal intercourse but ineffective in reducing the rate of sexually transmitted infection. They also reduce the likelihood of contraceptive use. Additionally, it has been reported that pledgers replace vaginal intercourse with other sexual activities, such as oral or anal sex. At least one study has found no difference in the sexual behavior of pledgers and non-pledgers after controlling for pre-existing differences between the groups.
