BACKGROUND INFO
___________________________________________________________________________________________________________________
This script implements the RAND 36 - Item Health Survey 1.0 version of the Medical Outcomes Study (MOS) Short Form
Health Survey (SF-36). It was developed at RAND as part of MOS. It differs from the commercially available MOS SF-36
in the scoring algorithm. The following articles/webpages were used to develop this script:
Ware, J., Jr., & Sherbourne, C.D. (1992). The MOS 36-Item Short-Form Health Survey (SF-36): I. Conceptual Framework
and Item Selection. Medical Care, 30, 473-483.
Ware, J.E. Jr. & Gandek, B, (1998). Overview of the SF-36 Health Survey and the International Quality of Life Assessment
(IQOLA) Project. Journal of Clinical Epidemiology, 51, 903-912.

All RAND surveys are in the public domain.

The RAND36-Item Health Survey contains 36 questions that assess the following 8 scales (+ 1 extra):
Factor 1: Physical Health (PCS) (summary measure)
Physical Functioning (PF): questions 3-12 (10 items)
Role-Physical (RP): questions 13-16 (4 items)
Bodily Pain (BP): question 21-22 (2 items)
General Health (GH): questions 1,33,34,35,36 (5 items)
Factor 2: Mental Health (MCS) (summary measure)
Mental Health (MH): questions 24,25,26,28,30 (5 items)
Role-Emotional (RE): questions 17,18,19 (3 items)
Social Functioning (SF): questions 20,32 (2 items)
Vitality (VT): questions 23, 27, 29, 31 (4 items)
Self-reported Health Transition: question 2
By default, participants are required to answer all the questions in this script.

DURATION
___________________________________________________________________________________________________________________
the default set-up of the script takes under 5 minutes to complete
___________________________________________________________________________________________________________________
DATA FILE INFORMATION
___________________________________________________________________________________________________________________
The default data stored in the data files are:
(1) Raw data file: 'rand36_ItemHealthSurvey.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 to a particular question (here in percentages); the anchors vary per question
For a more detailed check, check assigned 'optionvalues' under each question
under section QUESTIONS
q*_latency: latency of clicking "next" the last time the page was visited
(2) Summary data file: 'rand36_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)
the following scores save the percentage of total well-being (=100%) for each of the 8 (+1 extra) scales
selfreported_HT: self-reported health transition
=> Physical Health (PCS) (summary measure: mean percentage of the individual responses to target questions)
PF: Physical Functioning (PF): questions 3-12
RP: Role-Physical (RP): questions 13-16 (4 items)
BP: Bodily Pain (BP): question 21-22 (2 items)
GH: General Health (GH): questions 1,33,34,35,36 (5 items)
=> Mental Health (MCS) (summary measure: mean percentage of the individual responses to target questions)
MH: Mental Health (MH): questions 24,25,26,28,30 (5 items)
RE: Role-Emotional (RE): questions 17,18,19 (3 items)
SF: Social Functioning (SF): questions 20,32 (2 items)
VT: Vitality (VT): question 23, 27, 29, 31 (4 items)

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")
