Which type of stressor is characterized by being ongoing and unchanging?

The focus is on identifying a stressor that is both ongoing and unchanging, which aligns well with the concept of a chronic, permanent stressor. This type of stressor is consistently present and does not fluctuate over time, leading to prolonged exposure that can significantly impact an individual's mental and physical health.

Chronic, permanent stressors can include situations such as long-term financial difficulties, an unchanging demanding job, or continuous caregiving responsibilities. They create a persistent burden that can lead to issues like anxiety, depression, and physical health problems due to the lack of relief.

In contrast, acute stressors are typically short-term events that provoke a quick stress response but do not last long enough to be considered ongoing. Chronic, intermittent stressors involve patterns of stress that occur sporadically, rather than being constant. Lastly, stressor sequences refer to a chain of stressors that occur in succession, rather than a single unchanging source of stress. Thus, the identification of chronic, permanent stressors correctly captures the characteristics described in the question.
