Notes

The response category "PC" refers to surveys completed on personal computers. This category includes in-person CAPI/CASI interviews conducted by Add Health staff, and, therefore, does not reflect respondent device preference in all cases. The value 95 represents respondents who were interviewed by phone and those who elected to respond to the mailed paper survey. This excludes the twelve participants who responded by both the mail and web survey instruments. In these twelve cases, PLATFORM reports the device used to answer the web survey.
