Pathology is operationally defined by a set of rating scales which addresses the dimension at issue. In psychiatry, many dimensions are measured with rating scales e.g. anxiety, depression, hyperactivity, impulsivity, inattention, aggressiveness, extroversion, introversion, and emotional liability. The diagnostician's job is first to connect the symptoms/problems with which the patient presents with possible disorders that might be responsible for the symptoms/problems. For parents who consider medication treatment as the court of last resort, it may be sensible to recommend a trial of psychologic treatment with a time period built in such that continuation of problems after x number of weeks warrants reconsideration of medication. It is important to target psychosocial functioning separately from change in psychopathology. Other issues that complicate treatment include the presence of multiple disorders, which is the rule rather than the exception for children requiring medication treatment.
