Child Psychologist: These reports focus on the child and include attachment theory and observation. They can be forensic but generally they tend to be clinical.
Psychologists are licensed in their profession of choice and this is approved because of their training. Thus, some are both clinical and forensic. But professionally it is best to choose an expert who has the requisite licence for the report required.
All too often Psychologists try to convince themselves they can write forensic reports when they really cannot and do not understand the nuances of the discipline.
