BACKGROUND INFO

											*Purpose*
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 
only 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.

												*Overview*
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): question 3 (10 items)
Role-Physical (RP): question 4  (4 items)
Bodily Pain (BP): question 7, 8 (2 items)
General Health (GH): question 1, 11 (5 items)

Factor 2: Mental Health (MCS) (summary measure)
Mental Health (MH): question 9b-d, 9f, 9h (5 items)
Role-Emotional (RE): question 5 (3 items)
Social Functioning (SF): question 6, 10 (2 items)
Vitality (VT): question 9a, 9e, 9g, 9i  (4 items)

Self-reported Health Transition: question 2 

By default, participants are required to answer any of the questions in this script. At the end, researchers
have the option to give electronic feedback (->parameters.skipfeedback, page.feedback).


DATA FILE INFORMATION: 
The default data stored in the data files are:

(1) Raw data file: 'RAND36_ItemHealthSurvey.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: 'RAND36_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)

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)
/PF: 							Physical Functioning (PF): question 3 (10 items)
/RP:							Role-Physical (RP): question 4  (4 items)
/BP:							Bodily Pain (BP): question 7, 8 (2 items)
/GH:							General Health (GH): question 1, 11 (5 items)

=> Mental Health (MCS) (summary measure)
/MH:							Mental Health (MH): question 9b-d, 9f, 9h (5 items)
/RE:							Role-Emotional (RE): question 5 (3 items)
/SF:							Social Functioning (SF): question 6, 10 (2 items)
/VT:							Vitality (VT): question 9a, 9e, 9g, 9i  (4 items)

/count_PF10 -
/count_VT4:						counts the number of items for each of the 8 scales that were answered
								(the number at the end = number of items if all the items for the scale were answered)
/count_misseditems:				counts the number of items that were not answered (only relevant if responses are not required)
/misseditems:					stores the item numbers of the items that were not answered (only relevant if responses are not required)



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)
