Computers in
Psychological Evaluation
In the early 1980's a
series of articles were published in education, medical and psychological
journals that focused on the use of computers in education, health care and
psychological evaluation. Computers were first used by psychologists to
process data - usually true-false and multiple choice responses from paper
and pencil questionnaires. This raw data was processed into meaningful
scores and graphs that only trained professionals had access to and could
interpret. As computers became more available, new software was developed
that generated text that provided interpretative guidance to professionals.
Computer based test interpretation (CBTI) systems for psychological
evaluations were subsequently marketed to educators and health care
professionals. Based primarily on industry issues, the American
Psychological Association (APA) ethical codes were subsequently re-written
to allow developers to protect proprietary intellectual property. External
professional oversight of software performance was substantially eliminated
in favor of internal business oversight. Professionals who used these
programs no longer had a professional right to examine how a program worked
or generated an interpretation of the results.
Studies on the use of
computers in psychological evaluation and assessment recommended that
without further advancement a computer could not reach diagnostic
conclusions and fully replace face-to-face evaluation. Most state laws and
licensing boards asserted and continue to assert than only licensed and
qualified professionals can make a diagnosis. Despite these limitations,
CBTI systems continued to evolve in support of providing information. But
clinical results are still available only to licensed health care
professionals. Clinical report software is sold only to licensed health care
professionals who in most cases may not be trained at all in how to use
these tools.
Clinical reports are
currently not written for the lay person, but portions are shared with
clients. Many professionals and organizations have taken a position that
patients and parents may misunderstand CBTI and therefore could be harmed.
Professionals are cautioned to not give patients reports. They are
encouraged to go over the reports with patients in order to explain what the
result mean. Such concern is certainly warranted for a CBTI system that is
written for the audience of clinicians. It is important to recognize that
the concerns over harm based on misunderstanding technical reports dissipate
when the report is written specifically for adults (and not just clinicians)
in the general population.
Computer
based
interviews, surveys, questionnaires, intakes and histories have been under
development for years, but most of these simply process data, organize
information, generate a document using patient record format and give
professionals something to review. Software to perform these tasks has been
developed to run on desktop computers in a professional's office or waiting
room. These programs ask the patient questions about their history,
attitudes and behavior. No commercially available programs have been offered
that allow users to input and process information about their children and
other people.
The developers of
computer based interview systems initially experienced human resistance and
practical obstacles - primarily because people were not comfortable with
computers. More than one computer would also need to be available in offices
and patient waiting areas. People are accustomed to completing a brief paper
and pencil questionnaire on a clipboard. A computerized interview was
complicated, unfamiliar to most patients and was expensive to develop.
Answering a simple questionnaire on a computer in an office was far more
difficult and complicated 10 years ago than it is today. The software back
then had the unfortunate problem of not working all the time ("crashing").
Too many patients prove unwilling to come to an office appointment early
just to use a computer in a waiting area. Software development proved more
difficult than expected in order to design a computer based questionnaire
that a person could complete quickly in one sitting prior to their
appointment.
History of Internet and the Web
With access to the
internet we can interact with other people, gather information and search
for information in a knowledge-base almost instantaneously through fiber
optics and a communication network of computers across the planet. The
internet allows people to e-mail, voice and video-conference, transfer files
and search "Web” for information." E-mail and the Web are available in most
homes and even in the most remote areas of Alaska and the outback of
Montana.
The Web has seen a
great deal of change over the past decade. The technology has become faster
and easier to use. Instead of taking 10 minutes, files and images can now be
downloaded and displayed in seconds. Nearly a decade ago hundreds of
companies and millions of dollars flocked to Web in order to develop
"virtual" businesses that offered everything from clothing, to information,
advice or to merely provide a presence on the Web were customers and
stockholders could learn more about a company. Companies were formed to
create new software and hardware products that allowed companies to conduct
business on the Web.
Hiring a team of
Web
programmers and system engineers was necessary in the beginning. The cost to
develop a simple Web site could be as much as $70,000. A simple Web site
today can cost a few thousand dollars, and even less if you don't want to
take a few hours and do it yourself. Web sites can be constructed as easily
as using a word processing program. Years ago, sophisticated Web sites that
interacted with data bases and processed credit card transactions initially
cost anywhere from $250,000 to $500,000. There were many reasons why it cost
so much. The primary problem has been that there are serious challenges that
must to be overcome when trying to make software programs run over the Web.
The Web was never designed to help process information but rather to search
out and gather information that already existed in one standard format. Only
a wealthy company, or wealthy speculators, could afford to develop and
maintain a sophisticated commercial Web site.
The
Need for Behavioral Health Resources on the Web
For the most
part their problems go unrecognized. As a result they do not receive
necessary services.
The formula for health care today does
not address the unique or individual needs of teenagers. A diagnosis is
almost always made based on impressions and a few very brief interviews.
Even when children have mental health insurance coverage, the "gatekeepers"
who authorize payment for services tend to deny or limit services to a
significant degree. Few children will ever receive necessary and
comprehensive evaluations. These services are not covered by their health
insurance. Most children are minimally screened and the first option is
increasingly to medicate children for the psychological consequences of
overcrowded school, abuse, neglect, family dysfunction, poverty, divorce,
grief, alcohol and drug use. Very little time is spent evaluating the real
cause of their emotional and behavioral problems.
Many of the children of parent who can
actually afford medication will stop primarily because they do not see the
benefits. More importantly, the side effects such as insomnia, weight gain,
impotence, headaches and nausea are not worth it in their mind. Even more
alarming has been recent discoveries that the side effects of starting and
stopping medications can be dangerous. For more information see,
Finding the right help is a daunting task
for parents who know there is a problem but can't describe what they see in
a manner that will be taken seriously. Parents are often forced to appeal to
health care providers who are prone to either minimize parental concerns or
they side with children who typically minimize their behavior and omit
important information. Many parents are not trained to advocate effectively
to care-givers and insurance companies that profit by minimizing the amount
of care provided.
What kind of help do children with
behavioral and emotional problems need? Parent education, family counseling,
a psychological evaluation, a treatment program, boarding school, medical
care or psychotherapy? This list is nearly endless. Parents must choose from
and communicate with numerous professionals including counselors, clinical
social workers, psychologists, family nurse practitioners, psychiatric nurse
practitioners, neurologists, family physicians, psychiatrists and adolescent
psychiatrists to find help for their child’s problems. Parents become lost
without the information and guidance necessary to find help for their child.
Effective documentation and description of their child's history and
behavior is a critical element to help parents work effectively with health
care professionals. Parents in remote isolated areas do not have access to
mental health services. Poverty represents a tremendous obstacle for parents
who cannot afford an evaluation. Parents with children "at-risk" frequently
can't wait for a thorough face-to-face screening or clinical report. There
are not enough professionals in this country who are willing or able to work
with children who have behavioral and emotional problems.
Use of the Internet
in Mental Health Screening and Educational Consulting
Finding safe, effective and ethical
sources of information about treatment and treatment programs for youth
at-risk can be a challenge. Many parents and professionals are going to the
internet and Web to find support and solutions for troubled teens. Web sites
are being used by parents and professionals searching for educational,
intervention, emotional growth and treatment resources for youth. Likewise
these programs are making their presence known on the Web.
How Parents Currently
use the Web
The Web provides an excellent opportunity
for parents and professionals to compare, evaluate, and "shop" for
professional services, information resources and programs. Parents can go
directly to a Web site by entering the Web site address directly (also call
a URL) or they may use a search engine to locate information on a variety of
topics. The primary uses of the Web by parents and professionals include,
-
Researching problems. This might include gathering
information on parenting, problem behavior, specific disorders and treatment
approaches.
-
Finding professionals and programs.
Parents use the Web to locate professionals locally and nationally. Parents
also use the Web to locate boarding schools and treatment resources such as residential
treatment programs, therapeutic boarding schools, traditional boarding
schools, evaluation centers, wilderness therapy programs, outdoor schools
and adventure based programs.
-
Investigating a specific
professional or program. Many programs have Web
sites that provide information regarding their programs and services. Few
professionals maintain Web sites that provide detailed information about
their background and practice.
-
Finding consumer protection
information. This might include
finding News Room, articles and other information resources that are intended to
support public health, safety, referrals and the delivery of professional
services.
How Programs Currently
use the Web
Programs use the Web for a variety of
purposes. The Programs use the Web primarily to generate referrals and to
encourage parents and professionals to contact programs. Secondary purposes
are to facilitate admissions, public relations and to foster better
communication between programs, professionals and parents.
Differences between programs can be
tremendous. In addition, the amount of information and detail provided by
programs on their Web site can vary a great deal. This can make it difficult
to investigate programs on the Web. Contact information and a general
overview is usually provided on most Web sites. A few programs provide
detailed information pertaining to the program's ownership, structure,
staffing, philosophy, cost, policies and procedures. The best Web sites
provide complete, detailed, clear and honest descriptions of their program.
The Web is also being
used by schools and treatment programs to gather information from parents
that can be used to evaluate the appropriateness of a child's admission. A
few Web sites are using questionnaires that "screen" prospective youth and
offer "advice" regarding the appropriateness of admitting a child. Close
examination will reveal that there are two types of screening and advice
systems available on the Web. The first are those that almost invariably
recommend placement in the program that pays for the Web site. The second
types are those that don't recommend programs but instead offer a brief
interpretation and recommend the user obtain qualified help.
Many of these so called
screening Web sites seem to be no more than a ploy developed by marketing
people who are completely unqualified and remain anonymous despite inquiry.
Many of these questionnaires are manifestly unfit for their proposed use. Parents reaching one of these
Web sites are lured into completing a brief
questionnaire after which the results are submitted on-line. An automated
reply is returned with feedback and recommendations. Screening
questionnaires that are available on the Web are very simple, provide little
or no data processing, and reflect only the simplest form of results. The
real difference between these questionnaires is whether or not the results
are a ploy intended to scare parents into admitting their child into a
program that funds the Web site.
The
Future of Educational Consulting and Mental Health Screening on the Web
In order to envision
the future of software programs that operate on the Web we must first
consider the programming languages and “platforms” available to us. There
are many methods, but some lend themselves to the Web more than others.
Brief screening tools that offer little information and recommend the Web
site’s treatment program should become a thing of the past. More powerful
and ethical approaches are possible.
Computers can already
be programmed to process histories and behavioral rating information
quickly. Data processing is easy. Generating individualized reports and
recommendations is not. The type of computer system necessary to educate,
guide and empower parents is referred to as "expert systems." A
search of the top search engines would suggest that there does not appear to
be any expert systems for health care operating on the Web.
An expert
system is
a software program that can be designed to simulate the logic of people such
as teachers,
physicians, psychologists or psychiatrists. There are a number of ways to
accomplish this. A programming language designed specifically for could be used, or a language could be used based on a data processing
language that can implement Bayesian, Boolean and "fuzzy" systems. There are two
additional and essential elements that are more important than the language
used. One must hire a knowledge engineer and then put this person to work
with an expert in a domain of knowledge (a psychologist, physician, etc...).
Knowledge engineers are essential because they have the skills to define
decision processes and to consider the relevant information used by
professionals.
The process of
developing can be lengthy and expensive. Developers must be
persistent and well funded. A new advisory or expert system in a domain of knowledge
will invariably fail, but subsequent revisions and refinement can
increasingly and accurately approximate conservative professional judgment.
Finding an expert and knowledge engineer who can work effectively together
is the biggest challenge. Finding an expert who is also a knowledge engineer
is nearly impossible.
Expert
systems,
as defined here, are sophisticated screening applications for
mental health that can be used as follows.
-
To identify
individuals who exhibit behaviors associated with psychiatric disorders.
-
To identity patterns
of behaviors associated with specific behavioral, emotional and
psychological problems that are not psychiatric disorders.
-
To identify
individuals who exhibit specific behaviors associated with a risk of
violence, injury, accidental death or suicide.
-
To monitor and
evaluate progress or deterioration in behavior.
-
To provide users
with education and recommendations necessary to seek qualified
consultation and evaluation.
-
To educate parents,
caretakers and professionals regarding referral, intervention and
treatment options.
-
To help users
document a child’s history, behavior, problems and needs.
-
To support parents,
caretakers and professionals who are seeking information and resources for
youth with emotional, behavioral and psychological problems.
-
To provide guidance
and options for professionals conducting interventions for youth at-risk.
Questionnaires
developed by a psychologist working with a knowledge engineer can provide an
objective approach to evaluation by directing the rater’s response in a
reliable manner to specific questions supported by meaningful scales that
are associated with clinically valid content. Systematic interviews on-line
can minimize inferences and biases that create errors in omission or the
overemphasis of behavior and historical information that can create errors
in conclusion. The raters or "informants" completing these questionnaires
must know the child, be capable of reading the questionnaire and they must
answer all mandatory questions. In most cases only a few questions can be
answered "Don't Know" for the results to be valid. Failure to correctly
answer questions provides a less reliable and therefore less valid and
useful report.
The use of behavioral
ratings and checklists is already a commonly used method for assessing
children, adolescents and adults. These approaches can effectively identify
symptoms and signs of educational, behavioral and mental health problems.
Behavioral observations and ratings over time and from multiple sources can
provide information about the progress of treatment and whether or not a
child’s condition or behavior is getting worse.
Any expert system
focused on behavioral health will necessarily utilize empirical and clinical evaluation
procedures. This will mean that existing scales to measure behavior must be
incorporated and new scales must be developed. Standardized measures as well
as other valid clinical methods must be blended into the expert system's
procedures. This is not a task for an inexperienced knowledge engineer,
programmer or expert.
Ensuring privacy and
security are important factors when developing an expert system for the Web. The ability
to provide security as well as threats to security has grown over the past
decade. The internet and Web was not initially designed for security.
Privacy and security were after thoughts. But unlike a year ago, data
gathered on the Web can now be protected by powerful encryptions that are
virtually unbreakable. The chances of someone intercepting and reading a
transmission is nearly zero because encrypted data could take a hundred
years to decipher. Actual Web sites can also be certified "Hacker-Safe"
daily (99.9% safe) by external computer security services that can run over
2000 internal security checks daily. The next generation of operating
systems (the software than runs other software) is already being designed
specifically to eliminate hacking. It may soon be far easier to break into a
building and steal a computer from a bank vault in broad daylight.
Summary
More than simply
gathering and processing information, the Web can be used to educate and
empower people to make decisions and to seek further help in a timely
manner. The real advantage of developing online systems is that of saving time and
the ability to gather a great deal of information quickly and process that
information is a reliable manner with valid results. Professionally written
reports based on extensive face-to-face interviews and surveys can take a
professional three to four weeks to complete. Time is always a factor when
parents are dealing with a youth at-risk. A properly designed expert computer system
will promise
reliable, valid and useful results that can be generated and displayed on a
parent’s computer screen confidentially and in seconds. This process could
empower parents and give them information based on everything they know.
Parents are no longer completely dependent on professionals who may not be
available. And while online screening services cannot diagnose children, or replace
face-to-face evaluations, the result can be used by qualified consultants,
educators and health care professionals to guide and refine subsequent
placement, evaluation and treatment decisions. This can save time. With
online expert systems, consulting and evaluations that would otherwise take a month,
could take place in a day or less than a week. The use of a Web based expert
system, in the comfort of a parent's home, can provide parents with a
reliable means to document their concerns and to support subsequent
educational and health care decisions. Best of all, reports and
recommendations that normally cost over $1200 can be generated for 5 to 10
percent of that cost.
