Strictly religious adolescents grow up in highly religious contexts with orthodox beliefs and practices that usually contrast with those of pluralist and secularized societies that can be perceived as promoting unhealthy religious identity development. For these adolescents, religious identity development may be a challenge; however, there seems to be a lack of theoretical and empirical understanding of how these adolescents develop their religious identities. To address this, a literature review was conducted, and 15 studies were selected after the application of selection criteria. This review focuses on the characteristics of these studies to understand the religious identity development of strictly religious adolescents. Implications for theory development and further empirical research are discussed.
