This script implements a computer version of the paper-and-pencil version CIA as published by:

Bohn K, & Fairburn CG. The Clinical Impairment Assessment Questionnaire (CIA 3.0). In Fairburm CG (ed).
Cognitive Behavior Therapy and Eating Disorders. New York: Guilford Press, 2008.

From Appendix III:
"The Clinical Impairment Assessment questionnaire (CIA) is a 16-item self-report measure of 
the severity of psychological impairment due to eating disorder features (Bohn and Fairburn, 2008). 
It focuses on the past 28 days. The 16 items cover impairment in domains of life that are typically affected by
eating disorder psychopathology: mood and self-perception, cognitive functioning, interpersonal functioning and work performance.
The purpose of the CIA is to provide a simple single index of the severity of psychosocial impairmente secondary to 
eating disorder features."

The default data stored in the data files are:

(1) Raw data file: 'CIA.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 the participant spent on the surveypage with this particular question
								(the last time this particular surveypage was visited) (in ms)

(2) Summary data file: 'CIA_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)
/countresponses:				counts how many questions a participant answered 
/totalscore:					total of all answered questions (independent of number of responses)
/meanscore:						mean score based on all answered questions
/CIA_impairmentscore:			stores the global CIA impairment score (0-48) 
									IF at least 12 questions were answered (in the case of missing questions (max. 4), the
									meanscore is used to estimate the missing values)
									IF fewer than 12 questions were answered, the stored value will be
									'not calculated - too few responses' (see Bohn & Fairburn, 2008)

The 16 questions are set up as radiobutton questions with 4 answer choices.
There are 4 questions per surveypage - participants can go back and forth.
No answer is required.

Instructions are originals with minor edits to refer to the computer set-up.

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

/quitinstructions:			the instructions to quit the questionnaire (default: none given)
								Note: the quitcommand can be changed under DEFAULTS
