The development of the American College Health Association-National College Health Assessment III: An improved tool to assess and enhance the health and well-being of college students
Abstract
This article describes the development of the American College Health Association-National College Health Assessment III (ACHA-NCHA III), a widely used comprehensive survey that assesses college students' health behaviors and outcomes at the institutional and national levels. Only the second major revision since the ACHA-NCHA was established in 2000, the ACHA-NCHA III launched in Fall of 2019. Background on the purpose and history of the ACHA-NCHA will first be provided. Then the systematic steps taken to create a new and enhanced version of the survey will be recounted. An overview of the final ACHA-NCHA III instrument will be given, and future directions for the survey post-implementation will be discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
