Which psychological issue was identified in Sarah Kathryn Horton?

The correct choice identifies impaired physical mobility as the psychological issue associated with Sarah Kathryn Horton. Impaired physical mobility often stems from a combination of physical and psychological factors that can affect an individual's ability to move freely and engage in daily activities. It can be influenced by underlying conditions, such as pain or anxiety, which may limit a person's willingness or ability to move.

In the context of psychological issues, impaired physical mobility can contribute to feelings of helplessness or frustration, reinforcing the psychological impact on the individual's overall well-being. By addressing impaired physical mobility, healthcare providers can provide interventions that not only aim to improve physical function but also enhance quality of life by promoting independence and mobility, ultimately addressing psychological distress associated with the inability to move freely.

The other options refer to different concerns. Severe anxiety, for example, focuses on a heightened state of worry or fear that can affect various aspects of life but does not specifically relate to mobility. Chronic pain, while a significant issue, primarily addresses persistent discomfort rather than mobility itself. Impaired vision relates to sensory limitations rather than the psychological aspect of mobility impairment. Focusing on impaired physical mobility encapsulates a broader view that addresses both physical and psychological components, making it the correct choice in this context.
