Test Evaluation
Clinicians utilize the PDD Behavior Inventory test"to identify children at risk for Autism and
other Pervasive Developmental Disorders (Mackler, K, Thornedike, T, 2017).
Purpose of Test
The PDD Behavior Inventory test is used to determine whether a child has autism or another
type of intellectual disability. Clinicians utilize the test as a quick screening tool. In addition, this
exam evaluates troublesome behaviors and acceptable language and social abilities in children at
risk of developmental problems. Bryna Siegal of the University of California created and
improved the PDD exam. Today, there are several variants. (K. Mackler and T. Thornedike,
2017).
Type of Test/Scoring
The purpose of the test is to assess developmental behavior. Problem-solving, sensory and
perception, visual behaviors, types of food and touch behaviors, social issues, and social
awareness, as well as all social situation, language and the ability to do other non-specific
abilities, hearing ability, speech skills, the ability to understand spoken language skills, empathy,
anger, and any other non-specific problem areas within any aspect of one's life, are all tested to
determine a chi's potential. Through an interview technique, parents also submit information to
physicians about missing milestones and other behaviors witnessed by their children in various
settings. Finally, the parents of the children who have been tested receive the PDD Behavior
Inventory test results (Mackler, K, Thornedike, T, 2017).
Normative Sample
This study's sample cohort included three hundred sixty-nine parents of children aged 18 months
to 12.5 years. The youngsters had autism spectrum disease and had missed substantial
developmental milestones, which met the PDD test's criteria. According to the sample,
Caucasian moms made up the majority of the participants. The vast majority of these women
have completed some form of post-secondary education. Furthermore, the Autism Diagnostic
Interview-Revised the Autism Diagnosis Observation Scale to diagnose 92 percent of
participants with autism (ADOS). In the professional PDD manual, you may find further
information regarding age distribution and ethnicity. As a result, the participants' sample
sufficiently reflects the PDD test's intended demographic. Furthermore, they are within the same
age range (18 months to 12.5 years) and have been diagnosed with autism or show signs of
autism or other intellectual difficulties (Mackler, K, Thornedike, T, 2017).
Administration
An individual or a group of people can take the PDD Behavior Inventory test. The test can be
written down on a computer or with pen and paper. The test administrators will use the setting in
which the test is administered. Parents will keep track of their children's progress, teachers will
keep track of their student's progress, and the clinician will keep track of everything and finish
the test. The extended version of the test takes about 30-45 minutes, while the standard version
takes about 20-30 minutes. The test is available to trained clinicians, yet the evaluations did not
specify what credentials were required to obtain the test items. The professional manual, parent
and teacher rating forms, parent and teacher score summary forms, and profile forms include the
$230 test package (Carey, K, T, 2007).
Reliability
Internal reliability for all domains was assessed to be moderate to high, ranging from 80 to 90
percent. And this is based on 237 children who had both a parent and a teacher, or two different
teachers, complete the PDD Behavior Inventory test forms. The test-retest cycle lasts anywhere
from three months to three years, on average. Although the sample size for the test-retest (28
children) was insufficient, this test-retest reliability demonstrates the efficacy of therapies and
diagnosis of autism or other intellectual disorders. In this case, testing reliability on a more
significant number of participants over a shorter time would have been more successful. And the
period spanning three months to three years is quite long (Carey, K, T, 2007).
Validity
During the test review, concept validity, criterion-related validity, and clinical validity were also
found. In addition, the construct validity of problem-solving, social awareness, and
communication was investigated. Many different autism rating scale tests were compared, with
correlations ranging from.00 to.84, to determine criterion-related validity. Clinical validity was
also investigated by comparing several autistic rating scale tests such as the ADI-R, ADOS-G,
VABS, and seizure history with information from the professional manual. The evaluation
concludes that the validity of the PDD test as a diagnostic tool is limited, and clinical validity is
insufficient to demonstrate the test's effectiveness. As a result, according to the evaluation, the
PDD Behavior Inventory test should only be used for research. It cannot be recommended for
clinical use until more testing, and retesting have been performed (Carey, K, T, 2007).
Justification
I chose the PDD Behavior Inventory view because they are instrumental in my current position.
In an entry-level role at a Dallas mental health facility, I now work with youngsters. To gain life
skills and replace bad conduct with positive behavior, I provide one-on-one therapy to children
on the autism spectrum and those with any other underlying intellectual challenges. The PDD
Behavior Inventory were exciting to read about since they demonstrate yet another test that can
be done rapidly in many situations to diagnose a child with autism or another common disease.
The PDD Behavior Inventory also discussed how interventions for children identified with a
disease may or may not be working. The children's sample has already been evaluated. Therefore
the test would look at the effectiveness of the intervention. And, because I work directly with this
group, this would be valuable in my area. In the future, I plan to advance my career by attending
graduate school to finish the prerequisites for my counseling degree. And this would also help
me grow my career in the same sector, working with the same people. This exam would be
helpful in my future evaluation because it is proved to be a quick way to diagnose people with
disorders and evaluate the effectiveness of interventions.
Bible Text
The PDD behavior Inventory fit in with the goals and responsibilities of Christian professionals
as we are called to carry on God's work on earth. As followers of Christ, we should always do it
through the Lord with whatever we are doing. (Hebrews 13:16 King James Version) says, "But
to do good and to communicate, forget not: for with sacrifices God is well pleased. God has
given each of us an offering and expectations that no matter what that gift is, we always carry it
out with love and kindness, as Christ would do. This test fits in with that expectation of the Lord
as the developer and the clinicians who would potentially use this test are using their platform
and their gift to help others who need it. Using this test for a diagnosis opens the door to
interventions and help that individuals need. Being that door of hope for a family is carrying out
precisely what God wants from us, being his shepherds on earth. (Romans 13:7, N.I.V.) also
says, Pay to all to whom is owed to them; taxes to whom taxes are owed, respect to whom
respect is owed, revenue to whom revenue is owed, honor to whom honor is owed." if we have
the ability and opportunity to help someone, we must do so as this is what the Lord wants from
us. He wants us to help others whenever we can. So, if it is possible to give this test to help a
family, someone should do it to better their lives and spread the light and hope of the Lord.
Conclusion
In conclusion, the PDD Behavior Inventory test is great in review for the future. As of 2014,
there was not enough validity or testing to use in a clinical setting. To make the test more
effective, the developers should retest in a shorter period as they are averaging one year with a
full-time frame spanning three months and three years. It would also show more effectiveness by
making the test longer, as the longest the trial will take at the highest level is only 45 minutes. I
feel like 45 minutes to give a test with life-altering news is too short. The test's positives are that
the interview and rating process spans different environments and people, such as at home with
parents, in school with teachers, and the office with a clinician. The test may not reach much of a
population right now as most of those tested in the trial were Caucasian women. Perhaps if a
more extensive and more diverse population were tested, there would be different results.
