#' U.S. Student Questionnaire Problem-Solving Vignettes
#'
#' @details
#' Obtained from the PISA 2012 questionnaire responses given to 15-year olds,
#' we selected 12 items under three vignettes and four item stems to measure
#' problem-solving strategies applied by students.
#'
#' - Vignette **(a)**:
#'   - Suppose that you have been sending text messages from your mobile phone
#'     for several weeks.Today, however, you can’t send text messages.
#'     You want to try to solve the problem.
#'     - **ST96Q01**: I press every button possible to find out what is wrong.
#'     - **ST96Q02**: I think about what might have caused the problem and what I can do to solve it.
#'     - **ST96Q03**: I read the manual.
#'     - **ST96Q05**: I ask a friend for help.
#' - Vignette **(b)**:
#'   - Suppose that you are planning a trip to the zoo with your brother.
#'      You don’t know which route to take to get there.
#'     - **ST101Q01**: I read the zoo brochure to see if it says how to get there.
#'     - **ST101Q02**: I study a map and work out the best route.
#'     - **ST101Q03**: I leave it to my brother to worry about how to get there.
#'     - **ST101Q05**: I know roughly where it is, so I suggest we just start driving.
#' - Vignette **(c)**:
#'   - Suppose that you arrive at the train station.
#'     There is a ticket machine that you have never used before.
#'     You want to buy a ticket.
#'     - **ST104Q01**: I check how similar it is to other ticket machines I have used.
#'     - **ST104Q04**: I try out all the buttons to see what happens.
#'     - **ST104Q05**: I ask someone for help.
#'     - **ST104Q06**: I try to find a ticket office at the station to buy a ticket.
#'
#' @section Answer Coding:
#' All items were reverse-coded such that responses categories begin with
#' negative responses at 0 and go to 3 for a positive responses.
#'
#' - **0**: I would definitely not do this.
#' - **1**: I would probably not do this.
#' - **2**: I would probably do this.
#' - **3**: I would definitely do this.
