This script implements the Balanced Inventory of Desirable Responding as described in:

Paulhus, D. L. (1984). Two-component models of socially desirable responding. 
Journal of Personality and Social Psychology, 46, 598-609.

The BIDR is intended to measure self-deceptive positivity and impression management.

40 7-point Likert questions
1-20: assess self-deceptive positivity
21-40: assess impression management

The default data stored in the data files are:

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

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

q*_response:					scores given for response selected (in assigned values) - reversed items are automatically reversed scored
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: 'bidr_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)
/SDP:							score for the self-deceptive positivity scale (0-20)
/IM:							score for the impression management scale (0-20)
BIDR_total:						total score for the BIDR (0-40)

all responses < 6: score as 0
all responses >= 6: score as 1
