Interprofessional collaboration and trusting parent-professional relationships can be key to delivering interprofessional care to meet the needs of expectant and new parents in vulnerable positions. This, however, presents challenges. This study aimed to gain deeper understanding of how and under what circumstances trusting parent-professional relationships develop and work within interprofessional team-based care for this group, from the professionals' perspectives. Realist evaluation was undertaken based on 14 semi-structured, realist interviews with midwives and health visitors and 11 observations. Multiple interrelated mechanisms were identified including patient/family-centered care, timely and relevant interprofessional involvement in care, gentle interprofessional bridging, transparency of intervention roles and purposes, and relational continuity. Good interprofessional collaboration was a primary condition for these mechanisms. Developed, trusting relationships supported parents' engagements with interprofessional care and constituted a supportive safety net that promoted parenting skills and coping abilities. We identified harmful mechanisms: distanced encounters, uncertainty of interprofessional involvement, and compromising the safe space. These mechanisms caused distrust and disengagement. Ensuring trusting parent-professional relationships within interprofessional team-based care demands each professional involved competently engages in relational work and interprofessional collaboration. Uncontrollability is thus influenced regarding interpersonal connection and potentially gives an explanation when trust-building efforts fail.
