Social robots and their interactions with children are becoming increasingly sophisticated, with the emergence of child-robot relationships as a likely result. However, adequate measurement instruments
that tap into concepts associated with child-robot relationship formation are scarce. We aimed to develop three measures that can
be used to assess children’s closeness to, trust in, and perceived social support from, a social robot. We established the
validity and reliability of these measures among 87 Dutch children aged 7 to 11 years old. Because of their shortness, the
measures can efficiently be applied by scholars aiming to gain insight into the general process of child-robot relationship
formation and its specific sub-processes, that is, the emergence of closeness, trust, and perceived social support.
