These measures were created by Bob Pianta, Batten Bicentennial Professor of Early Childhood Education and founding director of CASTL. Included below are three measures developed by Pianta, along with manuals explaining their use and related articles. There is no charge for the use of these measures in educational research. No wording or rating scales of any items on the measures should be modified. It is permissible to translate a measure for use in educational research; please send a copy of completed translations to [email protected]. Permission is also granted to publish studies in which one of the measures has been used.
Student Teacher Relationship Scale (STRS)
The STRS is a teacher-report instrument designed for teachers of children between the ages of 3 and 12 that measures a teacher’s perception of conflict, closeness and dependency with a specific child.

Reaction to Diagnosis Interview (RDI or RXDX)
The RDI is a standardized, reliable interview asking parents to describe their diagnostic experience of a chronic disability in their children. Based on their responses, parents are classified as either 'resolved' or 'unresolved' with regards to the child's diagnosis. This measure is no longer used or supported in Pianta's research, but may be used at no charge.
Child-Parent Relationship Scale (CPRS)
The CPRS (Pianta, 1992) is a self-report instrument completed by mothers or fathers that assesses their perceptions of their relationship with their son or daughter. The 15 items are rated on 5-point Likert scales and the ratings can be summed into groups of items corresponding to conflict and closeness subscales. It is applicable to children ages 3-12. This measure is no longer used or supported in Pianta's research, but may be used at no charge.
