WAIS - Wechsler Adult Intelligence Scale Ethical and Clinical Application Questions and Answers

Question 1

A psychologist is administering the WAIS to a 25-year-old examinee who recently immigrated and has been learning the local language for two years. The examinee produces a Verbal Comprehension Index (VCI) score that is significantly lower than their other index scores. Which of the following is the most ethical and clinically sound interpretation?

Accepted Answer

The VCI is likely an underestimate of the examinee's true verbal reasoning abilities due to cultural and linguistic factors.

Answer

The VCI is heavily dependent on language and accumulated cultural knowledge. For an individual who is not a native speaker or is unfamiliar with the dominant culture, a low VCI score is more likely to reflect these factors rather than a true deficit in underlying verbal ability. Ethical interpretation requires the psychologist to consider the context of the examinee's background and explicitly state that the score may not be a valid representation of their actual abilities.

Question 2

According to the APA Ethical Principles of Psychologists and Code of Conduct, which of the following actions constitutes the most significant breach of test security?

Accepted Answer

Photocopying the copyrighted WAIS record forms to avoid the expense of purchasing new ones.

Answer

Photocopying copyrighted test materials like record forms is a direct violation of copyright law and a serious breach of test security. Publishers invest heavily in the development and standardization of these instruments, and their integrity relies on the use of authentic materials. The other options describe appropriate and ethical practices for storage, professional consultation, and disposal of records.

Question 3

An examiner is conducting a WAIS assessment with a client who has a significant motor impairment, making it impossible for them to manipulate the blocks for the Block Design subtest. What is the most appropriate and ethical course of action?

Accepted Answer

Skip the subtest and prorate the index score based on the remaining subtest scores, if administration rules permit.

Answer

Standardized administration is crucial for the validity of WAIS scores. When a physical disability directly interferes with the ability to perform a task as designed, the subtest cannot be validly administered. Modifying the administration by giving verbal instructions or unlimited time changes the cognitive demands and invalidates the norms. The correct procedure, as outlined in the test manual, is to spoil the subtest and prorate the relevant index score if the rules for proration are met.

Question 4

During the informed consent process for a WAIS evaluation, which of the following elements is ESSENTIAL for the psychologist to communicate to the client?

Accepted Answer

The purpose of the assessment, how the results will be used, and the limits of confidentiality.

Answer

Ethical guidelines, such as those from the APA, mandate that informed consent for assessments includes a clear, understandable explanation of the nature and purpose of the evaluation, who will receive the report, and any legal or ethical limits to confidentiality (e.g., risk of harm). Predicting scores or guaranteeing outcomes is unethical, and providing answers to items would invalidate the test results.

Question 5

A psychologist has completed a WAIS assessment for an adult client seeking career counseling. Which of the following represents the best practice for providing feedback?

Accepted Answer

Scheduling a feedback session to discuss cognitive strengths and weaknesses in clear, jargon-free language, linking them to the client's career questions.

Answer

Ethical and effective feedback is a collaborative process that translates complex test data into meaningful information for the client. The psychologist should use understandable language, focus on the pattern of strengths and weaknesses revealed by the index scores (not just the FSIQ), and directly relate the findings to the original referral question—in this case, career planning. Simply sending a report or withholding information are not client-centered or ethical practices.
