[Excerpt] Congress has held hearings and introduced legislation addressing the interrelated topics of the quality of mental health care, access to mental health care, and the cost of mental health care. The mental health workforce is a key component of each of these topics. The quality of mental health care depends partially on the skills of the people providing the care. Access to mental health care relies on, among other things, the number of appropriately skilled providers available to provide care. The cost of mental health care depends in part on the wages of the people providing care. Thus an understanding of the mental health workforce may be helpful in crafting policy and conducting oversight. This report aims to provide such an understanding as a foundation for further discussion of mental health policy.
