NCHA Ontario Canada Reference Group Executive Summary Spring 2016

The ACHA-National College Health Assessment II (ACHA-NCHA II) is a national
research survey organized by the American College Health Association (ACHA) to
assist college health service providers, health educators, counselors, and administrators
in collecting data about their students’ habits, behaviors, and perceptions on the most
prevalent health topics.
ACHA initiated the original ACHA-NCHA in 2000 and the instrument was used nation
wide through the spring 2008 data collection period. The ACHA-NCHA now provides
the largest known comprehensive data set on the health of college students, providing
the college health and higher education fields with a vast spectrum of information on
student health. A revised survey, the ACHA-NCHA-II, has been in use since the fall
2008 data collection period.
Please note the ACHA-NCHA II is not appropriate for trend comparison with items
from the original ACHA-NCHA survey. Directly comparing pre- and post-redesign
estimates on similar data points, without taking into account the impact of the survey’s
redesign, can lead to an erroneous conclusion.
