Evaluating parent-child interactions is a difficult and challenging task. It requires strong ethics and clear focus to collect valid information in an appropriate and facilitating manner. This task is of utmost importance especially when children are at the edge of care, or when uncertainty exists about the quality of dyadic interactions. Assessment of Parent-Child Interactions (APCI) aims to meet these challenges with its non-threating and revealing approach. APCI is an observational improvisation-based assessment model measuring the actual interactions between parent and child.
