Wechsler Ethical and Cultural Considerations Questions and Answers

Question 1

A psychologist assesses a recently immigrated child who is an English Language Learner.
The child's scores on the Wechsler scale show a significantly lower Verbal Comprehension Index (VCI) compared to their Fluid Reasoning Index (FRI) and Visual Spatial Index (VSI).
What is the most ethically sound interpretation of this score profile?

Accepted Answer

The VCI score is likely an underestimate of the child's true verbal ability due to language and cultural factors.

Answer

The score profile is conclusive evidence of a specific language-based learning disability.

Answer

The test administration was invalid, and all results, including non-verbal scores, must be discarded.

Answer

The child possesses exceptionally high nonverbal intelligence that compensates for their verbal deficits.

Question 2

Which of the following best defines 'test bias' in the context of psychometric assessments like the Wechsler scales?

Accepted Answer

The test systematically underestimates or overestimates the true ability of individuals from a particular cultural or linguistic group.

Answer

The test produces different average scores for different cultural or ethnic groups.

Answer

The test content includes items that are unfamiliar to every examinee, regardless of background.

Answer

The test is administered by an examiner from a different cultural background than the examinee.

Question 3

An examiner needs to assess a child who speaks only a language the examiner does not. According to ethical best practices, what is the most critical consideration when selecting and using an interpreter for a standardized Wechsler administration?

Accepted Answer

The interpreter must be trained in the procedures of standardized assessment, understand their role is to be impartial, and be fluent in the specific dialect.

Answer

Using a family member as the interpreter to ensure the child is comfortable and rapport is strong.

Answer

The interpreter should only translate the child's final answers, not the examiner's instructions or prompts.

Answer

The use of any interpreter automatically invalidates the test scores, so they should only be used for informal observation.

Question 4

When reporting the results of a Wechsler assessment for an individual whose cultural and linguistic background differs significantly from the normative sample, which of the following actions is an ethical requirement for the psychologist?

Accepted Answer

Including a detailed statement in the report about how cultural and linguistic factors may have influenced performance and should be considered in the interpretation.

Answer

Adjusting the final scores upward by a standard percentage to account for the cultural disadvantage.

Answer

Reporting only the non-verbal scores and concluding that the verbal scores are invalid.

Answer

Stating that the scores are a definitive and fixed measure of the individual's innate cognitive ability.

Question 5

The Flynn effect, the observed long-term increase in IQ test scores, has a significant ethical implication for test interpretation. What is the primary concern related to this phenomenon?

Accepted Answer

Using outdated test norms can lead to an inflation of scores, potentially resulting in misdiagnosis or incorrect placement.

Answer

It proves that intelligence is primarily determined by environmental factors, not genetics.

Answer

It suggests that non-verbal subtests are becoming less valid measures of intelligence over time.

Answer

The effect is only observed in Western cultures, creating bias when tests are used internationally.

Question 6

Which of the following represents the most appropriate and ethical first step for an examiner when preparing to assess an individual from a cultural background with which the examiner is unfamiliar?

Accepted Answer

Seek consultation or supervision and educate oneself about the examinee's culture and potential impacts on testing.

Answer

Proceed with the standard battery, assuming the Wechsler scales are culture-free.

Answer

Modify challenging verbal items to make them more culturally familiar to the examinee.

Answer

Administer only the non-verbal subtests to avoid any potential for cultural bias.
