Which of the following is a common sign of depression?

The common sign of depression among the options provided is the loss of interest in activities. This symptom, known as anhedonia, is a core feature of depressive disorders. Individuals experiencing depression often find that activities they once enjoyed no longer bring them pleasure or satisfaction. This loss of interest can apply to hobbies, social gatherings, or even day-to-day tasks.

Understanding this sign is crucial in the nursing practice because it can significantly impact a patient's quality of life and their engagement in treatment. Recognizing anhedonia helps healthcare providers to identify those who may need further evaluation for depression and tailor interventions accordingly. Addressing this symptom can facilitate conversations about the patient's experiences and feelings, which is integral to establishing rapport and trust in the therapeutic relationship.
