Final answer:
Proper handwashing involves psychomotor skills, cognitive understanding, and affective attitudes towards hygiene. Barriers to effective handwashing include laziness, lack of resources, and underestimation of its importance in preventing disease spread.
Step-by-step explanation:
Proper handwashing is crucial in preventing the spread of infectious diseases caused by pathogens. Effective handwashing involves using soap and warm water and rubbing your hands together for at least 20 seconds. To further understand this, we can look at the psychomotor, cognitive, and affective domains applied to handwashing.
The psychomotor domain involves the physical skill of handwashing, including the mechanics of scrubbing and rinsing. The cognitive domain requires understanding the importance of handwashing and remembering when and how to do it correctly. Lastly, the affective domain covers one's attitudes and feelings towards handwashing and its importance in health.
However, there are barriers to mastering proper hand washing. Laziness, lack of knowledge, insufficient resources such as soap and water, and underestimation of the effectiveness of handwashing can hinder good hand hygiene practices.
