BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements The Adolescent Risk Behavior Screen (ARBS) as described in:

Jankowski, MK, Rosenberg, HJ, Sengupta, A, Rosenberg, SD, & Wolford, GL (2007). Development of a  Screening Tool to 
Identify Adolescents Engaged in Multiple Problem Behaviors: The Adolescent Risk Behavior Screen (ARBS). 
Journal of Adolescent Health, 40, 180.e19 –180.e26.
										
___________________________________________________________________________________________________________________
OVERVIEW
___________________________________________________________________________________________________________________	
Participants fill out a 9 item survey to assess risk for high risk behavior in adolescents.

___________________________________________________________________________________________________________________	
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: 'arbs.iqdat' (a separate file for each participant)

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)
									Scales: 
									1: 1 (never)-4 (always)
									2,3,5: yes (2)/ no(1) 
									4: 1 (0 times) - 3 (2 or more times)
									6, 8: 1 (very wrong)- 4(not wrong at all); "I don't know" -> 3
									7: 1 (no risk) - 4 (great risk); "I don't know" -> 3
									9: 1 (none)-5 (five or more)
									
								In all questions, higher scores reflect higher risk
									
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: 'arbs_summary*.iqdat' (a separate file for each participant)

computer.platform:				the platform the script was run on (win/mac/ios/android)
script.startdate:					date script was run
script.starttime:					time script was started
script.subjectid:					assigned subject id number
script.groupid:					assigned group id number
script.sessionid:					assigned session id number
script.elapsedtime:				time it took to run script (in ms); measured from onset to offset of script
script.completed:				0 = script was not completed (prematurely aborted); 
									1 = script was completed (all conditions run)


radiobuttons.gender.response:	the selected gender
textbox.age.response:			the entered age

expressions.totalscore:			the totalscore based on all answered questions
									Range: 9-30
									The higher the score the greater the risk
									
values.count_answeredquestions: 	counts all answered questions
expressions.meanscore:			calculates the mean score (used as substitute if not all questions are answered)
expressions.ARBS_score:			the ARBS score (based on totalscore)
									!!!Note: for 1 or 2 missing questions => the mean is substituted
									If more than 2 questions are left unanswered, the totalscore is not calculated in this script
expressions.riskassessment:					totalscore_ARBS > 17: high risk; totalscore_ARBS <= 17: not high risk (if not enough data => "Cannot be determined")
								"For most purposes, we recommend using a cut-off of greater than 17 for both girls and boys." (Jankowski et al, 2007)

QUESTIONNAIRE SET-UP & SCORING
___________________________________________________________________________________________________________________	
* age/gender survey questions
* 9 item survey to assess risk for high risk behavior in adolescents
* lowest risk answer for each questions receives a score of 1 => minimum score = 9 (highest score = 30)
* the questions in this script are not required to be answered
To change: go to QUESTIONS and change /required = true to /required = true

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:

/pageinstructions:			the instructions that appear at the top of each surveypage
