Community agencies and practitioners around the globe seek opportunities to learn various assessment tools and interventions rooted in attachment theory. However, information regarding the feasibility of implementation and sustainability of these tools once participants have been trained to use them, is limited. This study investigated the perceived acceptability, feasibility, utility, relevance, fidelity, and sustainability of the Atypical Maternal Behavior Instrument for Assessment and Classification-Brief (AMBIANCE-Brief) among practitioners who had taken a training. Practitioners (N = 59) who attended a virtual AMBIANCE-Brief training originating from Canada between June 2020 and November 2021 completed an online follow-up survey. Practitioners reported that they primarily used the AMBIANCE-Brief for case conceptualization (68%). Additionally, 95% agreed that the AMBIANCE-Brief was relevant to their clinical practice, 98% agreed it was useful for their clinical work, 76% agreed that it was feasible to implement into their clinical work, and 59% found it easy to incorporate into their treatment planning with clients. Findings suggest that the AMBIANCE-Brief may be acceptable, feasible, and useful for practitioners. Avenues for continuing to evaluate the AMBIANCE-Brief include cross-cultural validity, coder drift, and booster sessions. Additional work clarifying how practitioners integrate the measure into practice would be valuable.
