The WSSQ is a 12-item Likert-type measure of weight-related self-stigma. WSSQ items are rated on a scale of 1 (completely disagree) to 5 (completely agree). Sum scores are calculated for the full scale and each subscale. Items 1–6 constitute the self-devaluation subscale, and items 7–12 constitute the fear of enacted stigma subscale (Lillis et al. 2010).
scoring_wssq(data, items = 1:12, keep = TRUE, nvalid = 5, digits = NULL)
A character vector with the WSSQ item names ordered from 1 to 12,
or a numeric vector indicating the column numbers of the WSSQ 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 5.
Integer of length one: value to round to. No rounding by default.
The function returns 5 variables:
nvalid.wssq.ena: Number of valid values of Fear of enacted stigma Scale (MAX=6)
nvalid.wssq.sel: Number of valid values of Self‐devaluation Scale (MAX=6)
score.wssq.ena: WSSQ Fear of enacted stigma Score
score.wssq.sel: WSSQ Self‐devaluation Score
score.wssq.glo: WSSQ Global Score
Number of items: 12
Item range: 1 to 5
Reverse items: none
Score range: 5 to 30 for each score
Minimal clinically important difference: none
Treatment of missing values: Summary scores are calculated
