Abstract
Despite practice models of trauma-informed care (TIC) emphasizing relational engagement and emotional attunement as critical to service delivery, the role of individual dispositions in shaping staff perceptions and behavior remains underexplored. This study examined how rejection sensitivity, a construct grounded in attachment theory, defined as a dispositional tendency to anxiously expect and overreact to perceived rejection, may influence staff perceptions of their roles and client relationships in residential mental health agencies implementing TIC. We further explored whether individual and organizational factors, including job satisfaction, prior trauma training, perceived isolation at work, and trauma-related knowledge, contribute to these associations. Regression analyses were conducted on survey data from 155 frontline staff across three agencies testing the associations between rejection sensitivity and two relational outcomes: perceptions of work and of clients. Higher rejection sensitivity was significantly associated with more disengaged perceptions of work and less empathic views of clients, even after controlling for demographic and contextual organizational variables. Job satisfaction and trauma knowledge emerged as domain-specific protective factors, reducing the negative impact of rejection sensitivity. The findings underscore the importance of addressing staff relational dispositions to sustain effective TIC implementation. Enhancing job satisfaction and trauma knowledge may help support staff engagement in trauma-informed practice.
