The work of psychological professionals is "people" work, the major portion of which involves them with issues including respect for human feelings, life's struggles, adaptation to life and even questions of life and death. Sometimes, the misgivings they inspire and the demands made of them exceed those placed upon other medical care givers.
由於心理專業人員的工作直接與「人」有關，人性的尊嚴、人生的掙扎、生活的適應、甚至生命的存亡，都是醫病關係的主要內容，他們引人疑慮和被要求的標準有時甚至高於一般醫療技術。
