F39EXPC - F39 Expected for visit

Col 6

This form/data was expected for this visit as part of the Main WHI study. On or prior to July 15, 1996, Form 39 (Cognitive Assessment) was expected at Baseline and years 1, 3, 6, 9 for a subsample of HT participants. After July 15, 1996 a Form 39 was expected at Baseline and years 1, 3, 6, 9 for HT participants who were 65 years or older at screening. NOTE: Form 39 was required annually for participants enrolled in the WHIMS Ancillary Study, however these were not considered expected for the Main WHI study.

Usage Notes:

This includes forms from the subsample of OS participants at year 6 that were enrolled in the three clinical centers participating in the WHI Osteoporosis sub study, as height and weight were collected on OS participants at year 6 by design; see table 16.1; on page 16-18b of volume 2.

Col 78

Usage Notes:

If a response is "unknown", "not attempted/disabled", or missing (and there is a "not attempted/disabled" option), the algorithm adjusts the scoring of the question to prevent the participant from being penalized as if she had given an incorrect response. The maximum points awarded for the question are subtracted from a counter set initially at 100. Once all questions have been tallied, this counter becomes the denominator in determining the score - the percentage of correct answers versus the number of total possible points for that participant. For example, if question 6.3 ("What season of the year is it?") is "not attempted/disabled" or missing, 1 point is subtracted from the total possible score. If this is the only such question on the Form 39, the score would be computed as a percentage of total points earned out of 99 possible points. If the total points discounted as missing, "unknown", or "not attempted/disabled" exceeds 20 (the denominator is less than 80), the test is not considered valid (indicated by a score of -9).
