====== UPPS-P Impulsivity Scale ======

In [[grants:habit:behavioral]] and [[:grants:SPA]], UPPS-P is collected as part of the [[:tools:redcap]] (previously qualitrics) behavioral survey battery.

The UPPS-P is a self-report questionnaire assessing **personality traits that lead to impulsive-like behaviors** in adults (though we use in adolescent sample). Consists of 59 items on a 4-point Likert scale, broken into five subscales: negative urgency (negurg), positive urgency (pu), sensation seeking (ss), perseverance (pers), premeditation (pre)

Scoring generates:
  * total impulsivity score (sum of each subscale score)
  * score for each subscale

scoring (for qualitrcs coded responses) is part of the LNCDR R package ([[https://github.com/LabNeuroCogDevel/LNCDR/blob/master/R/uppsp_score.R|uppsp_score.R]])
