Assessment and Diagnosis Principles Flashcards

A test developer wants to assess the reliability of a new anxiety scale. They administer 'Form A' of the scale to a group of participants. One week later, they administer 'Form B,' a different set of questions designed to measure the same construct, to the same group. They then correlate the scores from Form A and Form B. This procedure is designed to evaluate which type of reliability?

Answer: Alternate forms reliability

Alternate forms reliability (or parallel forms reliability) assesses the consistency of results across two different but equivalent versions of a test. This method is used to determine if the different sets of items are measuring the same construct consistently. Test-retest reliability would involve using the exact same test on both occasions.

The DSM-5-TR includes the Cultural Formulation Interview (CFI) to help clinicians gather and organize culturally relevant information. Which of the following is one of the four principal domains assessed by the core CFI?

Answer: Cultural perceptions of cause, context, and support

The core CFI is structured around four main domains: (1) Cultural Definition of the Problem; (2) Cultural Perceptions of Cause, Context, and Support; (3) Cultural Factors Affecting Self-Coping and Past Help Seeking; and (4) Cultural Factors Affecting Current Help Seeking. The other options might be discussed during an assessment but are not one of the four core organizing domains of the CFI.

A psychologist is conducting an initial intake interview with a new adult client who has been referred for anxiety. Which of the following should be the psychologist's first and most critical priority during the initial phase of this first session?

Answer: Establishing rapport and explaining the process of informed consent

Before any assessment or intervention can effectively begin, the psychologist must establish a therapeutic alliance (rapport) and fulfill their ethical obligation to ensure the client understands the nature and purpose of the assessment, confidentiality and its limits, fees, and their right to refuse services (informed consent). This creates a safe and transparent foundation for the entire therapeutic process.

A 24-year-old client presents with a one-week history of a persistently elevated and irritable mood, decreased need for sleep (sleeping 2 hours per night), racing thoughts, and excessive involvement in high-risk behaviors, including spending their entire savings on a 'guaranteed' business venture. The client's functioning is severely impaired, and they were brought to the clinic by concerned family members. The client has a history of major depressive episodes. Based on the DSM-5-TR, what is the most likely diagnosis?

Answer: Bipolar I Disorder

The key diagnostic feature for Bipolar I Disorder is the presence of at least one manic episode. The client's presentation—a distinct period of abnormally elevated/irritable mood and increased energy lasting at least one week with severe functional impairment—clearly meets the criteria for a manic episode. Bipolar II requires a hypomanic episode (less severe, no marked impairment) and a major depressive episode, with no history of a manic episode.

A psychologist is developing a new self-report questionnaire to measure 'scholarly aptitude' in graduate students. To ensure the items on the questionnaire adequately sample the full range of behaviors and knowledge related to this concept (e.g., critical thinking, research skills, academic writing), the psychologist's primary initial focus should be on establishing which type of validity?

Answer: Content validity

Content validity refers to the extent to which a measure represents all facets of a given construct. In this case, ensuring the questionnaire's items comprehensively cover the domain of 'scholarly aptitude' is the foundational step before assessing its relationship with other variables (such as convergent or criterion-related validity).

A psychologist administers the MMPI-3 to a client. The results are reported in T-scores. Which of the following correctly identifies the mean and standard deviation of a T-score distribution?

Answer: Mean of 50, SD of 10

T-scores are a standardized score format commonly used in psychological testing, such as the MMPI. By definition, the T-score distribution has a mean of 50 and a standard deviation of 10.
