🔍 Understanding Psychological Testing vs. Assessment
This paragraph introduces the distinctions between psychological testing and assessment. Psychological assessment is described as a broad process involving the collection and integration of psychology-related data for evaluation, utilizing various tools like tests, interviews, and observations. In contrast, psychological testing is specifically about measuring variables related to psychology, often using specific devices or procedures to obtain a behavior sample. The paragraph also highlights that testing is a component of the broader assessment process, with key differences in their objectives and methods.
📊 Key Assumptions of Psychological Assessment
This section outlines the fundamental assumptions underlying psychological assessment. The first assumption is that psychological traits and states exist and can be quantified. The second assumption is that behavior during testing can predict behavior outside of testing. The paragraph emphasizes the importance of recognizing both the strengths and weaknesses of psychological tests, as well as the presence of error in the measurement process. It also discusses the importance of fairness and unbiased methods in testing and assessment, likening tests to tools that can be used either properly or improperly.
🧠 Evaluating a Psychological Test: Key Considerations
This paragraph focuses on the criteria for evaluating the quality of a psychological test. It begins with the importance of understanding a test’s theoretical orientation and its relevance to the construct being measured. The usefulness of the test is another key factor, with considerations such as test length, reading level, and cultural bias potentially affecting its effectiveness. The process of standardization is crucial, involving norms derived from a standardization sample, which must be representative of the intended population. Finally, the paragraph discusses the importance of reliability and validity in tests, where reliability concerns the consistency of results, and validity addresses whether the test truly measures what it is intended to.

welcome to another video by
psychology for life
today i will be discussing differences
between psychological testing and
assessment
assumptions of psychological assessment
and evaluating a psychological test
the words assessment and testing are
often used interchangeably but there are
important distinctions between the two
psychological assessment is defined as
the gathering and integration
of psychology related data for the
purpose of making a psychological
evaluation
that is accomplished through the use of
tools such as
tests interviews case studies behavioral
observation
and specially designed apparatuses and
measurement procedures
on the other hand psychological testing
is the process of measuring
psychology-related variables
by means of devices or procedures
designed to obtain a sample of behavior
based on the definition you can see that
assessment is broader than
testing in fact testing can be
considered as one of the procedures used
in assessment
the first important distinction between
testing and assessment is impaired
objective
testing is usually carried out to obtain
an age
usually numerical in nature with regard
to an ability or attribute of a person
on the other hand assessment is done to
answer a referral question
solve a problem or arrive at a decision
through the use of tools of
evaluation the second major distinction
between testing and assessment is in the
process of carrying them out
testing can be done individually or in
groups but the process usually involves
administering a test and generating a
score
in assessment the process involves
carefully observing the individual
to determine not just his or her scores
but his or her psychological functioning
[Music]
a third major distinction between
testing and assessment
is in the skill of the evaluator testing
usually requires technician-like skills
in terms of administering and scoring a
test
as well as in interpreting a test
results on the other hand
assessment usually requires an educated
selection of tools of evaluation
skill in evaluation and thoughtful
organization and integration of data
[Music]
let us now turn to the assumptions of
psychological assessment
the field of testing and assessment has
a lot of disagreement and debate
however the assumptions that will be
discussed are the general agreements
that are held by those engaged in this
field without them the field
cannot move forward and carry out its
work
the first major assumption is that
psychological traits and states
exist a trait has been defined as any
distinguishable relatively enduring way
in which one
individual varies from another states
also distinguish one person from another
but are relatively less injury
the second major assumption is that
psychological states and traits can be
quantified and measured
once it is acknowledged the
psychological traits and states do
exist then it can also be assumed that
they can be quantified and measured
of course there are so many debates as
to the best way to measure these traits
and states
the challenge is to find the best way to
measure these straits and states in a
way that reflects their existence in
real life
the third major assumption is that test
related behavior
predicts non-test related behavior in
other words we expect that a person's
scores on different psychological states
and traits
will predict whether a person will
manifest these states or traits
in his or her life
the fourth major assumption is that
psychological tests and other
measurement techniques
have strengths and weaknesses they are
valuable instruments
so it is crucial to know their
limitations and to know when to use them
the fifth assumption is that various
sources of error
are always present in the measurement
process the key here
is to learn the techniques to minimize
these sources of error
or to mitigate their effects so that the
results of assessment
can be useful and not invalid
the sixth assumption is that testing and
assessment can be conducted in a fair
and unbiased manner
it is important to keep in mind that
tests are tools
and just like any other tools such as
hammers ice picks or wrenches
they can be used properly or improperly
we need to know the possible sources of
bias or unfairness in assessment
so that we can find ways to overcome
them
finally the last assumption is that
testing and assessment can benefit
society
a world without tests might seem
appealing but a world without tests will
probably lead to more chaos and disorder
many critical decisions are based on
assessment and testing
and the key is not to remove them but to
improve them
the last part of this overview is about
evaluating a psychological
test what are the characteristics of a
good psychological test
the first thing to consider in
evaluating a test is its
theoretical orientation before we can
evaluate whether a test is appropriate
we must first understand its theoretical
orientation
we must research the construct that the
test is supposed to be measuring
and then examine the process that the
test uses to measure this construct
the second thing to consider in
evaluating a test is its usefulness
if a test is too long the test takers
may become so frustrated
that the way they answer may invalidate
the results
other factors such as the reading level
of the test and culturally biased
items may also make it less useful
another important consideration in
evaluating a test is the process carried
out
in order to standardize it crucial here
is to check the norms to which the test
taker's scores will be compared
the norms are usually generated from a
sample of people called the
standardization sample
we need to ask three questions regarding
the standardization sample
1. does it represent the population of
intended test takers
2 is the standardization sample large
enough
and 3 are their subgroup norms these
points will be explained in more detail
in another video on test
standardization another important thing
to consider in evaluating a
psychological test is its reliability
the reliability of a test refers to its
degree of stability
consistency and predictability it
addresses the extent to which
scores obtained by a person are or would
be the same if the person is re-examined
by the same test on different locations
reliability will be discussed in more
detail in another video
perhaps the most important consideration
of call in evaluating a psychological
test
is its validity whereas reliability
addresses issues of
consistency validity assesses whether a
test
truly measures the trait it is supposed
to measure
validity is so important that another
video is dedicated to it

assessment
