WAIS - Wechsler Adult Intelligence Scale Ethical and Clinical Application Questions and Answers 1 — 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?
- The VCI score confirms a significant verbal learning disability that was previously undiagnosed.
- The entire assessment is invalid due to the language barrier and the results should be discarded.
- The VCI is likely an underestimate of the examinee's true verbal reasoning abilities due to cultural and linguistic factors. (Correct answer)
- The low VCI, in combination with the other scores, provides a clear picture of the examinee's innate cognitive potential.
Correct answer: The VCI is likely an underestimate of the examinee's true verbal reasoning abilities due to cultural and linguistic factors.
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?
- Storing WAIS test kits and completed protocols in a locked filing cabinet in the psychologist's office.
- Discussing a client's specific item responses during a formal, confidential case consultation with a qualified supervisor.
- Photocopying the copyrighted WAIS record forms to avoid the expense of purchasing new ones. (Correct answer)
- Shredding client record forms and test data seven years after the conclusion of services, in accordance with state law.
Correct answer: Photocopying the copyrighted WAIS record forms to avoid the expense of purchasing new ones.
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?
- Allow the client to verbally instruct the examiner on how to assemble the blocks.
- Skip the subtest and prorate the index score based on the remaining subtest scores, if administration rules permit. (Correct answer)
- Administer the subtest but allow the client unlimited time to compensate for the motor difficulty.
- Replace the Block Design subtest with an additional subtest from the Working Memory Index.
Correct answer: Skip the subtest and prorate the index score based on the remaining subtest scores, if administration rules permit.
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?
- The specific IQ score the client is likely to achieve based on the referral information.
- A guarantee that the assessment results will lead to a specific desired outcome, such as academic accommodations.
- The purpose of the assessment, how the results will be used, and the limits of confidentiality. (Correct answer)
- The correct answers to sample items to ensure the client is comfortable before the test begins.
Correct answer: The purpose of the assessment, how the results will be used, and the limits of confidentiality.
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?
- Emailing the full, unaltered psychological report to the client so they have all the technical data.
- Focusing the feedback session exclusively on the Full Scale IQ (FSIQ) as the most critical piece of information.
- Refusing to share any specific scores, as they are too complex for a layperson to understand.
- Scheduling a feedback session to discuss cognitive strengths and weaknesses in clear, jargon-free language, linking them to the client's career questions. (Correct answer)
Correct answer: Scheduling a feedback session to discuss cognitive strengths and weaknesses in clear, jargon-free language, linking them to the client's career questions.
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.
Question 6: Use of the WAIS is restricted to individuals who meet specific qualification levels. According to publisher standards and professional ethics, who is typically considered qualified to independently purchase, administer, and interpret the WAIS?
- A graduate student in their first year of a school psychology program.
- A human resources manager with a certification in workplace assessments.
- A licensed clinical psychologist with a doctoral degree and formal training in cognitive assessment. (Correct answer)
- A special education teacher with a master's degree and ten years of classroom experience.
Correct answer: A licensed clinical psychologist with a doctoral degree and formal training in cognitive assessment.
The WAIS is classified as a 'Level C' assessment tool, meaning its use is restricted to individuals with a high level of expertise in psychological assessment. This typically requires a doctoral degree in psychology or a related field, along with specific graduate-level coursework and supervised experience in administration, scoring, and, most importantly, interpretation of standardized cognitive tests. A licensed clinical psychologist meets these stringent requirements.
