In nrkoehler/qscorer: Procedures for Scoring Health-related Questionnaires

Description

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.

Usage

scoring_fsozuk7(data, items = 1:7, keep = TRUE, nvalid = 6, digits = NULL)

Arguments

data	a data.frame containing the F-SozU-K-7 items orderd from 1 to 7
items	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 data.
keep	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.
nvalid	A numeric value indicating the number of non-missing items required for score calculations. The default is 6.
digits	Integer of length one: value to round to. No rounding by default.
