Which of the following is NOT a symptom criteria in the diagnostic criteria for depression?

The correct answer is that an increase in energy is not a symptom criteria in the diagnostic criteria for depression. In fact, depression is typically characterized by a decrease in energy or fatigue, which can manifest as a lack of motivation and an overwhelming sense of tiredness, even with adequate rest.

On the other hand, suicidal thoughts, loss of interest in previously enjoyed activities, and changes in sleep patterns (which can include insomnia or hypersomnia) are all recognized symptoms that can be present in individuals diagnosed with depression. These symptoms reflect the debilitating impact of the disorder and contribute significantly to its identification and diagnosis.

In summary, while some individuals may experience fluctuations in energy levels, the hallmark of clinical depression is generally a reduction in energy rather than an increase, making it clear why an increase in energy does not fit the diagnostic criteria for depression.
