Question 1

A(n) __________ refers to the determination of the nature of an illness, while a(n) __________ refers to the procedure used to gather information necessary to identify the illness.

Accepted Answer

A diagnosis is the determination of the nature of an illness, and an assessment is the procedure used to gather information necessary to identify the illness.

Question 2

What was the most significant reason why the psychiatrists in the Beck et al. (1962) study found it difficult to agree?

Accepted Answer

E

Question 3

If the diagnostic category conduct disorder were to have subtypes that predict meeting vs. not meeting criteria for Antisocial Personality Disorder in adulthood, then this would be evidence for __________ of the subtypes.

Accepted Answer

If the subtypes of conduct disorder can accurately predict whether or not someone will meet criteria for Antisocial Personality Disorder in adulthood, then this demonstrates the subtypes' predictive validity.

Question 4

A good diagnostic system tries to do all of the following EXCEPT

Accepted Answer

The answer of A good diagnostic system tries to do...

Question 5

The study in which Beck et al. (1962) examined the reliability of psychiatrists' diagnoses using the DSM-I indicated that

Accepted Answer

The study by Beck et al. (1962) examining the reliability of psychiatrists' diagnoses using the DSM-I found that inter-rater agreement was lower than expected, highlighting concerns about the consistency of psychiatric diagnoses across different practitioners.

Question 6

Validity in diagnosis is best conceptualized as

Accepted Answer

Validity in diagnosis refers to the accuracy with which a diagnosis can predict future disorders or outcomes. Therefore, option C, which states that validity is the ability to predict disorders accurately, is the best choice.

Question 7

A clinical assessment could involve all of the following procedures EXCEPT

Accepted Answer

A clinical assessment may involve being asked questions about what is bothering you, filling out the MMPI, having interviews with family members, and possibly even having a CAT scan. However, it should not involve being told what illness you have without a proper diagnosis and evaluation. This is known as diagnostic overshadowing and can have negative effects on the patient's treatment and mental health. A diagnosis should only be given after a thorough assessment and evaluation by a qualified professional.

Question 8

The beginning of a modern system of classifying disorders can be attributed to

Accepted Answer

The answer of The beginning of a modern system of...

Question 9

Concurrent validity is concerned with the ability of a diagnostic category to

Accepted Answer

The answer of Concurrent validity is concerned with the ability...

Question 10

A diagnostic system that estimated lower levels of education and socio-economic status for persons actually diagnosed with schizophrenia disorder would be demonstrating __________.

Accepted Answer

Concurrent validity refers to the degree to which a test correlates with other measures of the same construct that are obtained at the same time. In this case, the diagnostic system is demonstrating concurrent validity because it is estimating lower levels of education and socio-economic status for persons actually diagnosed with schizophrenia disorder, which is consistent with other measures of these constructs.

Question 11

Two clinicians independently come up with the same diagnosis when examining a patient. This would demonstrate:

Accepted Answer

Interrater reliability refers to the degree of agreement among raters or judges. If two clinicians independently come up with the same diagnosis for a patient, it indicates a high level of interrater reliability because they are consistent in their evaluations. However, this does not necessarily mean their diagnosis is valid (correct or accurate), as they could both be consistently wrong. Validity refers to the extent to which a concept, conclusion or measurement is well-founded and likely corresponds accurately to the real world.

Question 12

Mr. and Mrs. Davidson took their son to a psychologist who diagnosed him as having conduct disorder. They decided to get a second opinion from another psychologist and were told their son was just going through a normal phase. This example reflects a problem of

Accepted Answer

The different diagnoses given by the two psychologists indicate a lack of reliability in the diagnostic process, where different professionals may reach different conclusions.

Question 13

A __________ diagnostic system is one that measures what it is supposed to measure, while a ____ diagnostic system results in the same result each time.

Accepted Answer

A valid diagnostic system accurately measures what it is intended to measure, ensuring the diagnosis is correct based on the symptoms or criteria being evaluated. A reliable diagnostic system, on the other hand, provides consistent results across different occasions, ensuring that the diagnosis is repeatable and stable over time.

Question 14

Jennifer complains about a sore throat, aching muscles, lack of energy, and occasional dizziness. These ___ may help her doctor determine what is wrong with her.

Accepted Answer

Symptoms are specific indications or manifestations of an illness or a medical condition experienced by the patient. In this case, the symptoms Jennifer is experiencing can help her doctor to determine the cause of her illness.

Question 15

Why has it been so difficult to develop the ideal system for classifying mental disorders?

Accepted Answer

It is challenging to develop an ideal classification system for mental disorders because determining which aspects of behavior are most important and how they should be categorized is complex and subjective.

Question 16

The International Statistical Classification of Diseases, Injuries, and Causes of Death (ICD),

Accepted Answer

The International Statistical Classification of Diseases, Injuries, and Causes of Death (ICD) is a listing of all diseases and mental disorders. It is not heavily influenced by psychoanalytic theory and is not developed by the American Psychological Association (APA). It is used by both physicians and psychologists, but the DSM (Diagnostic and Statistical Manual of Mental Disorders) is the main classification system used by psychologists in North America.

Question 17

Which of the following scenarios is most similar to the concept of reliability in making a diagnosis?

Accepted Answer

Reliability in diagnosis refers to the consistency of a measurement or assessment. Choice E illustrates this concept by showing that both individuals independently arrived at the same conclusion about the movie's fight scenes, indicating a consistent or reliable assessment of that aspect of the movie.

Question 18

The textbook indicates that validity is the second criterion used to determine the usefulness of a diagnostic system. This is because

Accepted Answer

Validity refers to how well a test measures what it is supposed to measure, while reliability refers to the consistency of the test results. If a test is not reliable (i.e., does not produce consistent results), it cannot be valid because inconsistent results cannot accurately measure the intended attribute. Therefore, reliability is a prerequisite for validity.

Question 19

If the diagnostic category Autism Spectrum Disorder included information about the IQ or mental ability profiles commonly observed in persons with the diagnosis, then the diagnostic category would be said to have __________.

Accepted Answer

Concurrent validity refers to the extent to which the results of a particular test or measurement correspond to those of a previously established measurement for the same construct. Including IQ or mental ability profiles in the diagnostic category would relate to concurrent validity as it involves comparing the diagnosis with established measures of cognitive ability.

Question 20

If there was a perfect relationship between a diagnosis of conduct disorder in early adolescence and a diagnosis of antisocial personality disorder in adulthood, this would be evidence for the __________ of the first diagnosis.

Accepted Answer

Predictive validity refers to the extent to which a diagnosis or measure is able to predict future outcomes or behaviors. So, if a diagnosis of conduct disorder in early adolescence was able to accurately predict a diagnosis of antisocial personality disorder in adulthood, this would be evidence of the predictive validity of the first diagnosis.

Quiz 3: Classification and Diagnosis

A(n) refers to the determination of the nature of an illness, while a(n) refers to the procedure used to gather information necessary to identify the illness.
