Variable 20Ab
date of last revision: 04/01/06
The manner in which interview data were collected from the person with brain injury.
1 In-person interview
2 Telephone interview
3 Questionnaire mailing
4 NA-data obtained out of window from secondary source
6 Variable did not exist at time data were collected
7 No data to be collected at this time (e.g., no funding)
8 No interview data provided by person with brain injury
1 numeric
Interview data includes all Form II data collected from the person with brain injury.

If multiple methods are used to collect data, record the method used the most with this participant.

Code 7 is not shown on Form II because it is a special purpose code and should not be used in normal data collection/submission.

Use code "4" for both V20Ab and V20Ac if most of the data were obtained out of window from a secondary source. These data must have originally been collected within window and must be high quality.

*Every effort should be made to collect data from the participant or an appropriately informed significant other. Data from other sources (indicated by code "4" ) should be entered only if: (1)it has not been possible to obtain that information from the person or SO during the follow-up window, (2) those data were originally collected during the follow-up window, and (3) the data meet TBIMS standards for data collection procedures and data quality standards.
Data were collected via telephone interview.

QUESTION: On the syllabus I have and on the list of Form II Syllabus changes, it is noted "Added code 7" but that code isn't on the new Form II. Should it be? 
ANSWER: This code is used only for very specific purposes that data collectors will not run into. So, the code should not be on the Form II.  (01-15-2004)
QUESTION: On the Form II, variable 20Ab & 20Ac now have a code "4". Do I understand this to actually be a form of chart review? How will this code be treated in calculation of follow-up rates in the Quarterly Report?  
ANSWER: The "4"code was added in response to a center's need to be able to enter a code for V20Ab and V20Ac for a few respondents who had withdrawn authorization during the follow-up window but re-authorized TBIMS data collection after the window had closed, and for whom, it turned out, data usable in their Form IIs were obtainable later from sources that had happened to have collected that information for clinical purposes, during the follow-up window. The key elements in this situation are: (a) data could not be obtained by TBIMS data collectors (or their proxies) from any source during the follow-up window, and (b) data that were appropriate for entering into the Form II were collected elsewhere during the follow-up window and became available to TBIMS data collectors after the follow-up window had closed. This is a rare situation. The availability of this new code should not affect your data collection practices or your use of the 1, 2, and 3 codes under any circumstances other than when the above two key elements are present. Form II data that are obtained by chart review during the follow-up window should be coded 1, 2, or 3, depending on how the original data collector obtained it for entering into the chart. In the Quarterly Report follow-up rates, the "4" code will be counted the same as the 1, 2, and 3 codes. That is, Form IIs with a "4" in V20Ab and V20Ac will be counted as having been submitted with data.   (12-31-1969)
