| Background: | The provided SAS programs were created by the National Cancer Institute (NCI). |
| Primary use / Purpose: | These SAS Programs are designed to perform specific data edits and create per-day and per-person summary variables from NHANES 2003-2004 accelerometer data. Users are able to modify these programs to implement alternative definitions of valid data, monitor wear periods, or activity bouts. There is also a program that converts data downloaded from ActiGraph accelerometers to the data layout used in NHANES. This enables the preparation programs to be used on ActiGraph data as well. Note that intermediate-level SAS programming skills are necessary for modifying the provided code. Technical support from NCI is limited. The SAS programs are accessible via the NCI website. |
| Psychometrics: | Not applicable. This is a set of SAS programs for data processing, not a psychometric tool. |
| Author of Tool: | National Cancer Institute (NCI) |

| Files: | The description implies there are multiple SAS program files related to data editing, summary variable creation, and ActiGraph data conversion, these files are available at the link provided above. |
