Derivation of DO-BITS, a score for predicting success on Love Island: a retrospective, observational cohort study

OBJECTIVE: To derive a score for finishing in the top three positions of the television show, Love Island, UK. DESIGN: A retrospective study was undertaken using data from all previous contestants. RESULTS: A score predicting show success termed DO-BITS (different coupling approaches [islanders pursuing one or many people on the show], Original islander [being on the show from the start], [being] Brunette, [having] intimate relationships on screen, Tradesman [occupation before being on the show] and Short name [having a four-letter first name]) was developed. The accuracy of this score in this derivation cohort yielded a C-statistic of 0.85. CONCLUSION: This simple, novel score provides a practical tool to assess the likelihood of success on Love Island.
