This study investigates the relationship between how families treat professionals (interpersonal justice) and the trust professionals have in families over time in organizations supporting individuals with intellectual disabilities. Data from 179 professionals was collected three times over four-week intervals. The findings highlight a double spiral model where interpersonal justice and trust mutually reinforce each other dynamically. Specifically, earlier interpersonal justice predicted later trust, which then influenced subsequent interpersonal justice, and vice versa. The study suggests that both interpersonal justice and trust act as key drivers in these dynamic processes.
