This is not a PCP tool but could be useful if you work with people with autism
The Coventry Grid (nothing to do with PCP but available here)
The Coventry Grid is an attempt to differentiate between autism and attachment problems based on clinical observations. The Grid has proved useful to clinicians and professionals working with children and adolescents. This is Version 2. If there are further revisions, they will always be found here. You can download the grid below.
