Final answer:
In pain assessment, the focus should be on physical, psychological, and social problems and factors. The biopsychosocial model emphasizes their interrelation, and understanding this model helps identify psychophysiological disorders.
Step-by-step explanation:
During pain assessment, the three problems and associated factors that should be focused on are physical problems and factors, which include physical disorders or diseases that can be worsened by stress; psychological problems and factors, which pertain to the impact of stress and emotional factors on psychological conditions such as anxiety or depression.
The biopsychosocial model suggests that health and illness are determined by an interaction of physical, psychological, and social factors, highlighting the multifaceted nature of pain perception. Understanding this model is crucial in identifying psychophysiological disorders such as cardiovascular disorders and asthma, which can be exacerbated by stress and emotional factors.
