There is a dearth of research on trauma bonding among victims of sex trafficking. This study aims to fill this gap by seeking to understand how service providers working with survivors of sex trafficking conceptualize and observe trauma bonding in their clients. This qualitative study involved interviews with 10 participants. Purposeful sampling was employed among licensed social workers or counselors. Two themes emerged: defining trauma bonding (with four subthemes: embracing intensity, power imbalance, distortion of love, and inescapability) and the development of trauma bonds (with three subthemes: universality, gendered, and grooming). These findings provide much-needed insight into the complexities of trauma bonding.
