maladaptive

This term is primarily used in clinical psychology and behavioral sciences to describe behaviors that prevent an individual from adjusting healthily to stress or environmental changes. It carries a strong connotation of dysfunction, suggesting that while a behavior might provide short-term relief, it creates long-term harm or instability.

In a professional or medical context, it is often contrasted with adaptive behaviors. It describes a failure of the biological or psychological system to reach an equilibrium with its surroundings, often manifesting as avoidance, aggression, or compulsive habits.
