This script implements a computerized version of the Police Stress Questionnaire (PSQ) as described in:

McCreary, D.R., & Thompson, M.M. (2006). Development of two reliable and valid measures of stressors in policing: 
The Operational and Organizational Police Stress Questionnaires. International Journal of Stress Management, 13, 494-518.

By, default this script runs the 'The Operational Police Stress Questionnaire' (PSQ-Op; 20 items) 
and the 'Organizational Police Stress Questionnaire' (PSQ-Org; 20 items) in order.
Test administrators have the option to run only of these scales by changing parameter settings under section
'Editable Parameters'.

2 surveys: PSQ-Op and PSQ-Org
Each questionnaire contains 20 7-point Likert scale items.
The final score for each scale is the average response score: the higher the final score, the more
policing stress is perceived by participant.

The default data stored in the data files are:

(1) Raw data file: 'policestressquestionnaire.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: 'policestressquestionnaire_summary.iqdat' (Inquisit Lab: one data file per 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)
/PSQ_Op:						average response score on the PSQ-Op questionnaire
/PSQ_Org:						average response score on the PSQ-Org questionnaire
								Note: the higher the score, the more policing stress is perceived by participant


Default Set-Up:
Script runs PSQ-Op (20 questions), followed by PSQ-Org (20 questions)
To run only one of the two questionnaires, go to section Editable Parameters and follow instructions.

Each question is responded to on a 7-point Likert scale with the anchors:
1  not at all stressful to 7 = very stressful

can be 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:

/pageinstructions:				contains the default instructions 

/runPSQ_Op:						true (1)= script runs PSQ-Op; false (0)=script does not run PSQ-Op
/runPSQ_Or:						true (1)= script runs PSQ-Org; false (0)=script does not run PSQ-Org
