The F-SozU-K-7 is a 7-item scale designed to measure perceived social support. Items are Likert-scaled (1 to 5). A total mean score ranging from 1 to 5 may be calculated.
scoring_fsozuk7(data, items = 1:7, keep = TRUE, nvalid = 6, digits = NULL)
A character vector with the F-SozU-K-7 item names ordered from 1 to 7,
or a numeric vector indicating the column numbers of the F-SozU-K-7 items in
Logical, whether to keep the single items and whether to return variables containing the number of non-missing items on each scale for each respondent. The default is TRUE.
A numeric value indicating the number of non-missing items required for score calculations. The default is 6.
Integer of length one: value to round to. No rounding by default.
The function returns 2 variables:
nvalid.fsozuk7: Number of valid values (MAX=7)
score.fsozuk7: F-SozU-K-7 Score
Number of items: 7
Item range: 1 to 5
Reverse items: none
Score range: 1 to 5
Minimal clinically important difference: none
Treatment of missing values:
If at least one item is missing, that F-SozU-K-7 score must not be calculated.
