Effectiveness of motivational interviewing in preventing subsequent adolescent pregnancies. A scoping review

Abstract
Introduction: The disruption of sexual education programs and the reduced availability of contraceptive services during the global health crisis have created significant challenges that may increase adolescent pregnancies. Although motivational interviewing has been effective in other areas of health, its use in preventing adolescent pregnancies remains limited.
Objective: The purpose of this review is to explore how motivational interviewing
can be useful in preventing subsequent pregnancies among adolescents.
Materials and methods: A scoping review was conducted following the PRIS-
MA-ScR 2020 guidelines, searching for studies from 2014 to 2024 in databases such as PubMed, Scopus, Dialnet, Redalyc, SciELO, and Google Scholar. Six rele-
vant studies were selected, including randomized controlled trials, cohort studies, and other approaches. Most of the studies were conducted in the United States between 2015 and 2020.
Results: The interventions reviewed include contraceptive counseling, telephone
follow-up with home visits, and a computer-assisted program, all based on motivational interviewing.
Discussion: Despite methodological challenges, such as specialized training and
logistics, the results suggest that this technique has significant potential to improve contraceptive use among adolescents and reduce unintended pregnancies.
Conclusion: This analysis highlights the need for further research on the impact of motivational interviewing on youth reproductive health.
