BACKGROUND INFO
___________________________________________________________________________________________________________________
This script implements the MOS sleep scale 1.0 as provided by:

and discussed in:

Medical Outcomes Study sleep measure. Sleep Medicine, 6(1), 41-44.
Scoring Algorithm can be obtained under:

Version 1.0. Los Angeles, CA.

OVERVIEW
___________________________________________________________________________________________________________________
The survey presents 12 sleep questions (by default, the questions are coded in such a way that participants
do not have to answer them) that make up 7 subscales (+ 2 extra).
___________________________________________________________________________________________________________________
DURATION
___________________________________________________________________________________________________________________
the default set-up of the script takes appr. 2 minutes to complete
___________________________________________________________________________________________________________________
DATA FILE INFORMATION
___________________________________________________________________________________________________________________
The default data stored in the data files are:
(1) Raw data file: 'mos_sleepscale.iqdat'
date, time: date and time script was run with the current group/subjectnumber
subject, group, session: with the current subject/groupnumber/session id
build: the Inquisit build
q*_response: response given (in assigned values)
Scale: all of the time - none of the time; no automatically attached values attached to response anchors
=> see summary data for numeric values
q*_latency: how much time (in ms) the participant spent on the surveypage with this particular
question (the last time this particular surveypage was visited)
(2) Summary data file: 'mos_sleepscale_summary*.iqdat' (a separate file for each participant)
inquisit.version: Inquisit version run
computer.platform: the platform the script was run on (win/mac/ios/android)
startdate: date script was run
starttime: time script was started
subjectid: assigned subject id number
groupid: assigned group id number
sessionid: assigned session id number
elapsedtime: time it took to run script (in ms); measured from onset to offset of script
completed: 0 = script was not completed (prematurely aborted);
1 = script was completed (all conditions run)
slpd4_sleepdisturbance -
slp9_sleepproblems: subscale scores
SLPQRAW_sleepquantity: Sleep Quantity Score (q2)
q1 -
q12_SP: scoring of the individual questions
(according to the scoring manual: "Note that items 4 and 12 are scored differently
depending upon which scale they are used in. When used in the sleep adequacy scale,
a higher score reflects less of a problem. When used in the sleep problems index, a
higher score reflects more of a problem." (Spritzer & Hays, 2003, p.2)
count_slpd4 -
count_slp9: count the number of answered items of a subscale

EDITABLE CODE:
___________________________________________________________________________________________________________________
check below for (relatively) easily editable parameters, stimuli, instructions etc.
Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment.
The parameters you can change are:
/instructions: Contain the surveypage instructions. The default instructions ("Please answer the following questions")
are not original to the survey and were addede by Millisecond Software.
/skipfeedback: true = no feedback is given (default)
false = feedback is given (-> page.feedback)
