Which of the following is a sign that individual coping strategies may not be adequate?

Experiencing emotional responses outside one's norm is indeed a significant indicator that individual coping strategies may not be adequate. When a person begins to react emotionally in ways that are inconsistent with their usual patterns—such as feeling excessive sadness, anger, or anxiety—it suggests that their current coping mechanisms are failing to manage the challenges they are facing. This could manifest as heightened emotional responses, overwhelming stress, or difficulty regulating feelings.

In contrast, feeling engaged in everyday activities, consistently finding joy in hobbies, and staying calm in stressful situations all reflect positive coping strategies and emotional regulation. Engagement in daily life and pleasure derived from hobbies are signs of effective coping, while the ability to remain calm under stress indicates a person's capability to manage pressures effectively. Thus, the presence of atypical emotional responses is a clear sign that an individual may need to reassess and improve their coping strategies.
