Which term describes a lack of ability to express joy and experience pleasurable activities?

The term that describes a lack of ability to express joy and experience pleasurable activities is anhedonia. In the context of mental health, anhedonia is a significant symptom commonly associated with mood disorders, particularly depression. It is characterized by a diminished interest in or the inability to enjoy activities that were once found pleasurable, which can include hobbies, social interactions, and even intimate relationships. This symptom can severely impact a person's quality of life, as it alters their capacity to engage with life fully and diminishes their emotional responses.

Understanding anhedonia is essential for social workers, as it can inform their approach when working with clients who may be experiencing depression or related psychological issues. Recognizing this symptom helps in devising appropriate interventions that may include therapy, support groups, or medication to help restore the ability to experience joy and engage in enjoyable activities.
