Final answer:
If an error in not reversing appropriately on a Wechsler subtest is discovered post-administration, consult the test's manual, consider ethical implications, discuss the issue with a supervisor or relevant party, and possibly re-administer the subtest or adjust scoring.
Step-by-step explanation:
If you realize that you failed to reverse appropriately on a Wechsler subtest after the administration is completed, the first step is to consult the manual for the specific assessment to see if there are any guidelines for this kind of error. If the manual does not provide a solution, or if the mistake could significantly impact the test results, it is essential to consider the ethical implications.
Considering that the accuracy of the results is paramount, you may need to be transparent about the error. This might involve discussing the issue with a supervisor or with the individuals interpreting the data. In some cases, it may be necessary to re-administer the subtest or adjust the scoring, if possible. It is important to document the mistake and the steps taken to remedy it to maintain the integrity of the assessment process.
