· A useful psychological test must be both valid (i.e., there is evidence to support the specified interpretation of the test results) and reliable (i.e., internally consistent or give consistent results over time, across raters, etc.).
It’s a valid and reliable questionnaire to evaluate severity and treatment responses (Pruett, 2020). Psychological Tests The DSM-5 helps determine whether someone has schizophrenia. A mental health provider can use cognitive and personality testing to determine if …
If general aptitude tests are not as predictive as they are reliable, then why do you think we rely on them so heavily? Module 62: The Dynamics of Change Define the following key terms 1. cohort 2. crystallized intelligence 3. fluid intelligence 4. intellectual disability 5. Down syndrome Answer the following questions 1.
Pre-treatment evaluations, particularly if you know a patient has been referred to you because of limited success in previous treatment or the patient has complex problems/presentation; When treatment has stalled and psychological assessment can be used to identify the factors limiting progress, and;
Agree with that! Longitudinal assessments often provide the best information. As new facts emerge, hypotheses change and the management plan changes accordingly.
Glad you liked the article. Psychiatric assessments are based on a bio-psycho-social approach and this means that whilst structured assessments are valuable, they may not tease out the interplay between the bio-psycho-social elements (i.e the causality). This requires a formulation and it is for this reason the case formulation plays such an important role. you can read more about that here. http://psychscenehub.com/ps...
Again, perhaps the most important element is that therapeutic assessments have a clinical impact about the equivalent to a similar period of therapy or counselling.
In clinical practice, the approach that hoof beats mean horses works most of the time but in some cases an alternate approach is required . In summary multidisciplinary collaboration is more likely to achieve positive outcomes and I often tell patients 'two heads are better than one.'
The degree of the relationship between various forms of a test can be evaluated by means of an alternate-forms or parallel-forms coefficient of reliability, which is often termed the coefficient of equivalence. Parallel forms of a test.
refers to consistency in measurement. And whereas in everyday conversation reliability always connotes something positive, in the psychometric sense it really only refers to something that is consistent—not necessarily consistently good or bad, but simply consistent.
It is a useful measure of reliability when it is impractical or undesirable to assess reliability with two tests or to administer a test twice (because of factors such as time or expense). The computation of a coefficient of split-half reliability generally entails three steps: Step 1.
refers to an estimate of the extent to which these different forms of the same test have been affected item sampling error, or other error.
Although they do not meet the requirements for the legitimate designation "parallel," alternate forms of a test are typically designed to be equivalent with respect to variables such as content and level of difficulty.
Parallel forms of a test exist when, for each form of the test, the means and the variances of observed test scores are equal.
is an estimate of reliability obtained by correlating pairs of scores from the same people on two different administrations of the same test. The test-retest measure is appropriate when evaluating the reliability of a test that purports to measure something that is relatively stable over time, such as a personality trait. If the characteristic being measured is assumed to fluctuate over time, then there would be little sense in assessing the reliability of the test using the test-retest method
An assumption in psychological testing and assessment is that psychological traits can be. measured. For this to be true, A. the reference group used must be people who exhibit and do not exhibit the trait. B. the test must take into account changes in the trait that can occur over time.
C. test developers must clearly define the trait constructs the test purports to measure.
C. is true only if the non-test-related behavior mimics the test-related behavior.
