What is psychological dependence?

Psychological dependence refers to a state in which an individual believes they need a substance or activity to function normally or to experience pleasure. This drive to medicate often stems from a desire to produce pleasurable effects or to relieve discomfort, anxiety, or distress. In the context of addiction, this can manifest in compulsive behaviors where the individual seeks the substance or activity due to the psychological cravings that arise from their mental state rather than physical withdrawal symptoms.

The other options do not accurately define psychological dependence. While the need for physical exercise relates to physical health and activity levels, it does not encompass the mental reliance on substances or behaviors. A condition resulting from injury focuses on the physical aspect of health, which is not relevant to the psychological facets of dependence. An emotional response to competition is more about the individual's feelings and reactions in a competitive setting, lacking the broader implications of dependence on substances or behaviors related to psychological needs.
