This script implements the MOS sleep scale 1.0 as provided by:
and discussed in:
Hays, Ron D., Martin, Susan A., Sesti, Anne M., & Spritzer, Karen L. (2005). Psychometric properties of the
Medical Outcomes Study sleep measure. Sleep Medicine, 6(1), 41-44.
Scoring Algorithm can be obtained under:
and is described in:
Spritzer, K. L. & Hays, R. D. (2003, November). MOS Sleep Scale: A Manual for Use and Scoring, Version 1.0. Los Angeles, CA.
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).
DATA FILE INFORMATION:
The default data stored in the data files are:
(1) Raw data file: 'MOS_SleepScale.iqdat'
date, time, subject: date and time script was run with the current subjectnumber
build: version of Inquisit
xxxx.response: response to a particular question (here in numbers)
xxxx.latency: latency of clicking "next" the last time the page was visited
(2) Summary data file: 'MOSSleepScale__summary*.iqdat' (a separate file for each participant)
script.startdate: date script was run
script.starttime: time script was started
script.subjectid: subject id number
script.groupid: group id number
script.elapsedtime: time it took to run script (in ms)
computer.platform: the platform the script was run on
/completed: 0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run)
/SLP9_sleepproblems: subscale scores
/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_SLP9: count the number of answered items of a subscale
/number_misseditems: counts number of questions that weren't answered
/misseditems: list of all unanswered questions
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)
