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
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.
DATA FILE INFORMATION:
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
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
