One symptom of a mood disorder is anhedonia, which means

Question

BlackTom AI · Accepted Answer

Anhedonia refers to the loss or marked reduction in the ability to experience pleasure from activities that were previously enjoyable.

1) Relevant knowledge points and concepts
- Anhedonia is a core symptom of major depressive disorder and other mood disorders. The term comes from Greek: a- (without) + hedone (pleasure).
- DSM-5 lists either depressed mood or markedly diminished interest/pleasure (anhedonia) as one of the primary criteria for a major depressive episode. Other common symptoms include changes in sleep, feelings of worthlessness, and indecisiveness, but those are distinct symptoms.

2) Step-by-step reasoning
- Read the stem: “One symptom of a mood disorder is anhedonia, which means…”
- Translate the term literally and clinically: an- (without) + hedone (pleasure) → inability to experience pleasure or diminished interest/pleasure.
- Compare each option to this definition.

3) (No numeric calculations required)

4) Why the correct answer is correct
- Option d states “an inability to experience pleasure,” which exactly matches both the literal meaning of anhedonia and the clinical description used in diagnostic criteria (diminished interest or pleasure). Therefore d is the correct and precise definition.

5) Why the other options are incorrect
- a. “a feeling of worthlessness” — this is a separate symptom of depressive disorders but not the meaning of anhedonia.
- b. “an altered pattern of sleep” — sleep disturbance (insomnia or hypersomnia) is another possible symptom of mood disorders, not anhedonia.
- c. “indecisiveness” — impaired concentration or indecisiveness can appear in depression but does not define anhedonia.

6) Conclusion
- The correct choice is d. an inability to experience pleasure, which matches the provided answer.
