Six months of worry: why GAD on the NCE is a clock, not a feeling
Anxiety items look like they test empathy for a worried client. They test a calendar. Here is the item that shows why, and the three durations you need to carry into the exam.

Anxiety items look like they test empathy for a worried client. They test a calendar. Here is the item that shows why, and the three durations you need to carry into the exam.
The practice item discussed here was written for this site in the style of the NCE. It is not a question from the actual exam. NBCC does not release its items, and candidates sign a nondisclosure agreement.
The item
A 41-year-old reports worrying about her job, her children's safety, her health and money "more days than not" for the past four months. She is restless, tense and sleeps poorly. She has never had a panic attack. Which diagnosis is MOST appropriate at this time?
A. Generalized anxiety disorder
B. Adjustment disorder with anxiety
C. Panic disorder
D. Unspecified anxiety disorder
Keyed answer: D. Every symptom fits GAD except the one that decides it: duration. GAD requires excessive worry more days than not for at least six months. At four months, with no identifiable stressor, the picture is real but does not yet meet criteria for a named disorder, so the exam wants the unspecified category.
What the item is really testing
Not whether you can recognize anxiety. Whether you will read the number before you read the symptoms. NCE anxiety vignettes almost always contain one duration, and that duration is the answer key. Four months of worry that would be GAD at six months is, on the exam, not GAD.
The temptation is strong because everything else fits. The candidate who has treated anxious clients for years knows this woman has GAD in every clinical sense. The exam is asking a narrower question: does she meet criteria today?
Why each wrong answer tempts you
A. The right disorder, too early. GAD is a six-month diagnosis; four months does not qualify.
B. Adjustment disorder needs an identifiable stressor within three months; multi-domain worry with no precipitant is not it.
C. No panic attacks are described, and panic disorder is defined by unexpected attacks plus a month of concern about them.
The three clocks in the anxiety chapter
Six months: generalized anxiety disorder, specific phobia, social anxiety disorder. All three carry the same duration, which is why they are often confused with each other and why the distinguishing feature is the object of the fear, not the timeline.
One month: panic disorder. Recurrent unexpected attacks followed by at least one month of persistent concern about more attacks or a change in behavior to avoid them. The attacks themselves are not the diagnosis; the month of worry after them is.
Four weeks in children, six months in adults: separation anxiety disorder. The one anxiety diagnosis with two clocks, and a favorite for items about school refusal.
Why "unspecified" is a real answer
Candidates skip the unspecified and other-specified categories because they sound like giving up. On the exam they are the correct answer whenever the picture is clearly clinical but a criterion is unmet, usually duration. Unspecified anxiety disorder says: this is anxiety, it is impairing, and it does not yet fit a named box.
Treat the unspecified option as a live candidate whenever a vignette gives you a duration that falls short. It is rarely a distractor when it appears.
Where the exam stops and the clinic begins
In practice you would begin treating this client as though she had GAD, and you would be right to. Worry postponement, relaxation training, cognitive work on intolerance of uncertainty, all of it applies. The exam is not asking what you would do. It is asking what the DSM-5-TR says she has right now.
That gap between clinical judgment and diagnostic criteria is where experienced counselors lose points. The fix is mechanical: underline the duration first, then read the symptoms.
One more clock to carry
Rule-outs. Before any anxiety diagnosis the exam expects you to exclude hyperthyroidism, caffeine and stimulant use, and withdrawal from alcohol or sedatives. If a vignette mentions a recent medication change, a new energy drink habit, or stopping a benzodiazepine, the answer is usually "assess for a substance or medical cause" rather than a named anxiety disorder.
