5. DIAGNOSING PDDNOS
The
DSM-IV suggests that the diagnostic label of PDDNOS be used
when there is a severe and pervasive impairment in the development
of reciprocal social interaction, verbal and nonverbal communication
skills, or the development of seemingly meaningless repetitive
behavior, interests, and activities, but when the criteria
are not completely met for a specific disorder within the
category PDD (e.g., Autistic Disorder, Rett's Disorder,
Asperger's Disorder). However, the DSM-IV framework has
not offered specific techniques or criteria for diagnosing
PDDNOS.
No Specific Test Available
Currently, no objective biological test, such as a blood
test or an X-ray examination, can confirm a child's PDDNOS
diagnosis. Diagnosing PDDNOS is complicated and much like
putting together a jigsaw puzzle that does not have a clear
border and picture. Therefore, it is reasonable to say that,
when a PDDNOS diagnosis is made, it reflects the clinician's
best guess. Obtaining an accurate diagnosis requires an
assessment conducted by a well-trained professional who
specializes in developmental disorders, usually a child
psychiatrist, developmental pediatrician, pediatric neurologist,
developmental pediatrician, child psychologist, developmental
psychologist, or neuropsychologist.
PDDNOS
Assessment
The
purpose of PDDNOS assessment is twofold: to gather information
to formulate an accurate diagnosis and to provide information
that will form the basis of an appropriate intervention
plan for the individual child and family. Assessment of
PDDNOS usually includes the following elements:
1.
Medical assessment
2.
Interviews with the parents, child, and child's teacher
3.
Behavior rating scales
3.
Direct behavioral observations
4.
Psychological assessment
5.
Educational assessment
6.
Communication assessment
7.
Occupational assessment
