Question 1Hard
A 33-year-old woman with a major depressive episode reports reactive mood, increased appetite, weight gain, and hypersomnia. She also says that for most of her adult life she has felt devastated by any criticism from supervisors, friends, or family, and this sensitivity is not limited to episodes of depression. Which feature best supports the atypical specifier?
Show answer and explanation
Correct answer: A. Long-standing pattern of interpersonal rejection sensitivity
The atypical specifier requires a long-standing pattern of interpersonal rejection sensitivity that causes significant social or occupational impairment, not merely transient sensitivity during a depressive episode. Excessive guilt, morning worsening, and psychomotor retardation are melancholic features.
From practice test 5 of our NCMHCE study guide (question 37). Original question, not an official exam item.
Question 2Hard
A client's AUDIT responses are 3 on item 1 (drinking frequency), 2 on item 2 (typical quantity), 4 on item 3 (binge frequency), 0 on items 4 to 6, and 1 on item 7 (guilt after drinking). Which interpretation is most accurate?
Show answer and explanation
Correct answer: A. The total score is above the screening cutoff, and the pattern is driven by hazardous alcohol use items rather than dependence symptoms; brief intervention is indicated.
The AUDIT total is 10, which is above the cutoff of 8 for hazardous drinking. Scores on items 1 to 3 reflect hazardous use, while the dependence items scored 0, making brief intervention more appropriate than dependence treatment or detoxification.
From practice test 8 of our NCMHCE study guide (question 55). Original question, not an official exam item.
Question 3Easy
A client with MDD reports that her mood is always at its worst right after waking and improves somewhat by evening. Which specifier is best supported?
Show answer and explanation
Correct answer: C. Melancholic features
Depression that is regularly worse in the morning is a listed melancholic feature. Atypical features would more likely involve hypersomnia and mood reactivity, and mixed features require manic or hypomanic symptoms.
From practice test 12 of our NCMHCE study guide (question 7). Original question, not an official exam item.
Question 4Hard
A client scores 22 on the PHQ-9. Which clinical action best reflects appropriate use of this result?
Show answer and explanation
Correct answer: B. Review which specific items are elevated and consider whether medical illness, medications, or other factors account for them before diagnosis.
An elevated scale score is not a diagnosis; the clinician must examine item-level responses and possible content overlap with medical or other conditions before applying DSM-5-TR criteria. Repeating the measure or switching instruments does not address the source of the elevation.
From practice test 2 of our NCMHCE study guide (question 81). Original question, not an official exam item.
Question 5Easy
According to the standard clinical cutoff for the Social Phobia Inventory (SPIN), a total score of _ or higher suggests a probable diagnosis of social anxiety disorder.
Show answer and explanation
Correct answer: B. 19
The SPIN's established screening cutoff for likely social anxiety disorder is 19. Scores below 19 are generally considered subclinical.
From practice test 10 of our NCMHCE study guide (question 26). Original question, not an official exam item.
Question 6Medium
In a study of a new depression screening instrument, the researchers plot a receiver operating characteristic (ROC) curve and report an area under the curve (AUC) of 0.87. What does this value most directly indicate?
Show answer and explanation
Correct answer: D. The test correctly ranks a randomly selected person with the disorder higher than a randomly selected person without the disorder 87% of the time
The AUC represents the probability that a randomly selected affected person has a higher score than a randomly selected unaffected person. It is not the sensitivity, specificity, or PPV at a particular cutoff.

Question 7Easy
A screening test for generalized anxiety disorder has a sensitivity of 90%. Which interpretation is correct?
Show answer and explanation
Correct answer: A. 90% of people with GAD test positive
Sensitivity is the proportion of people with the disorder who test positive on the measure. Positive predictive value, not sensitivity, describes the percentage of positive tests that are true cases.
From practice test 13 of our NCMHCE study guide (question 39). Original question, not an official exam item.
Question 8Medium
A 30-year-old client reports drinking 5 to 6 beers most evenings and scores 8 on the Alcohol Use Disorders Identification Test (AUDIT). Which interpretation is most accurate?
Show answer and explanation
Correct answer: D. The score of 8 meets the AUDIT cutoff for hazardous drinking, so further assessment is warranted.
An AUDIT score of 8 meets the cutoff for hazardous drinking. A positive screen indicates the need for further assessment, but it does not by itself establish an alcohol use disorder diagnosis.
From practice test 3 of our NCMHCE study guide (question 85). Original question, not an official exam item.
Question 9Medium
A client's PHQ-9 score drops from 18 to 14 after several sessions. The clinician knows that the minimally important difference for the PHQ-9 is 5 points. What is the most accurate conclusion?
Show answer and explanation
Correct answer: C. The client's change is within the range of measurement error and does not establish clinically meaningful improvement.
The minimally important difference is the smallest score change that reflects real clinical improvement rather than measurement noise; for the PHQ-9 it is 5 points. A 4-point drop does not cross that threshold, so it should not be interpreted as true improvement.
From practice test 2 of our NCMHCE study guide (question 47). Original question, not an official exam item.
Question 10Medium
A comprehensive exam used to evaluate a counselor intern's readiness for independent practice contains only multiple-choice questions about DSM-5-TR diagnostic criteria. It includes no items on ethics, case conceptualization, or rapport-building. The test is most deficient in which type of validity?
Show answer and explanation
Correct answer: D. Content validity
Content validity requires that a test represent all relevant parts of the domain it claims to measure. Excluding major domains of practice leaves the test deficient in content, not criterion or construct validity.
From practice test 13 of our NCMHCE study guide (question 31). Original question, not an official exam item.
Question 11Easy
The Structured Clinical Interview for DSM-5 (SCID-5) module for personality disorders is best described as which of the following?
Show answer and explanation
Correct answer: D. Clinician-administered semistructured interview that covers DSM-5 personality disorder criteria
The SCID-5 personality disorder module is a clinician-administered semistructured interview used to systematically evaluate DSM-5 personality disorder criteria. It is not a self-report measure, projective test, or informant checklist.
From practice test 8 of our NCMHCE study guide (question 24). Original question, not an official exam item.
Question 12Easy
A client completes the Fagerstrom Test for Nicotine Dependence and reports smoking their first cigarette within 5 minutes of waking. How many points does this response receive?
Show answer and explanation
Correct answer: D. 3 points
On the Fagerstrom Test for Nicotine Dependence, the time to first cigarette item is scored 3 points when the first cigarette is smoked within 5 minutes of waking. Earlier times receive higher scores because they indicate stronger nicotine dependence.
From practice test 13 of our NCMHCE study guide (question 43). Original question, not an official exam item.
Question 13Easy
On a 20-item self-report measure of generalized anxiety, all items correlate positively with one another and Cronbach's alpha is 0.91. This value is evidence of which form of reliability?
Show answer and explanation
Correct answer: D. Internal consistency reliability
Cronbach's alpha estimates internal consistency, the degree to which items on a scale measure the same underlying construct. Alternate forms and test-retest assess different reliability facets.
From practice test 13 of our NCMHCE study guide (question 51). Original question, not an official exam item.
Question 14Easy
A client with major depressive disorder, single episode, has loss of reactivity to usually pleasurable stimuli. Which one of the following symptoms, when present, would count toward the three required melancholic features?
Show answer and explanation
Correct answer: B. Significant anorexia with weight loss
Significant anorexia or weight loss is one of the six Criterion B features for melancholic features; the client already has loss of reactivity but needs at least three total. Appetite increase, leaden paralysis, and hypersomnia are features of the atypical specifier.
From practice test 5 of our NCMHCE study guide (question 85). Original question, not an official exam item.
Question 15Hard
A 34-year-old woman reports depressed mood and anhedonia nearly every day for the past two weeks. She has lost 12 pounds without dieting, wakes at 4 a.m. and cannot return to sleep, feels excessive guilt about being a burden to her family, and does not feel any lift in mood when her sister brings her favorite meal. She continues to go to work but struggles to concentrate. She has no prior episodes and no substance use. Which diagnosis is most accurate?
Show answer and explanation
Correct answer: D. Major depressive disorder, single episode, moderate, F32.1, with melancholic features
She meets six MDD criteria with noticeable but not incapacitating impairment, indicating moderate severity (F32.1), and she has loss of reactivity plus early morning awakening, weight loss, and guilt, which satisfies the melancholic features specifier. The other options misstate severity or omit the specifier.
