This script implements the RT-18 Risk Taking Questionnaire as described in:

de Haan, L., Kuipers, E., Kuerten, Y., van Laar, M., Olivier, B,. & Verster, J.C. (2011).
The RT-18: a new screening tool to assess young adult risk-taking behavior. 
International Journal of General Medicine, 4, 575–584.

18 yes/no questions about risk taking behavior.

The default data stored in the data files are:

(1) Raw data file: 'RT18.iqdat'

date, time, group, subject:		date and time script was run with the current group/subjectnumber 
build:							the Inquisit build 

q*_response:					response given (in assigned 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: 'RT18_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)
/TotalScore:					the sum of all individual scores (Range: 0-18)
								In general the response that suggests risk taking gets a point

/Factor1_RiskTakingBehavior:	the sum of all scores of questions that load on factor 1: q4, q5, q6, q7, q14, q15, q16, q17, q18
									=> Range: 0-9: the higher the score, the higher the reported risk taking behavior
/Factor2_RiskAssessment:		the sum of all scores of questions that load on factor 2: q1, q2R, q3, q8, q9R, q10R, q11R, q12, q13
									=> Range: 0-9: the higher the score, the more participant reported to do things without thinking about consequences

18 questions with yes/no questions: most yes-responses are suggesting of risk taking and are scored as a 1;
for a few questions the the no-response is suggesting of risk taking is scored as a 1

=> 1 = response suggests risk taking
=> 0 = response does not suggest risk taking

Questionnaire instructions can be easily edited under section Editable Parameters

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:
