BACKGROUND INFO

											*Purpose*
This script implements the Attitudes towards Chocolate Questionnaire published by:

Benton, D., Greenfield, K. & Morgan, M. (1998). The development of the attitudes to chocolate questionnaire, 
Personality and Individual Differences, 24, 513-520.
(http://www.sciencedirect.com/science/article/pii/S0191886997002158)


											  *Task*
24 slider questions (0-100 points each)
* 10 Guilt questions
* 10 Craving questions
* 4 Functional questions


DATA FILE INFORMATION: 
The default data stored in the data files are:

(1) Raw data file: 'AttitudesTowardsChocolateQuestionnaire.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: 'AttitudesTowardsChocolateQuestionnaire_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)
dropdown.gender.response:		the response to the gender question 
									Note: if response is 'other', the data are treated as "female" in this script for percentile rank determinations

/Craving:						Craving Score = mean score of all 10 craving (C) questions (0-100)
/Craving_percentile:			the percentile of the Craving Score based on normative data published in Table 3, p. 516, in Benton et al (1998)
								and linear interpolation for the gender indicated (!default is female in this script!)
									Note: for Males: the upper score reported is 81.4 (100%) - in this script: anything above 81.4 receives a rank of 100%

/Guilt:							Guilt Score = mean score of all 10 guilt (G) questions (0-100)
/Guilt_percentile:				the percentile of the Guilt Score based on normative data published in Table 3, p. 516, in Benton et al (1998)
								and linear interpolation for the gender indicated (!default is female in this script!)
									Note: for Males: the upper score reported is 70.6 (100%) and for Females it is 79.5 (100%)- in this script: anything above these scores receives a rank of 100%
																
/Functional:					Functional Score = mean score of all 4 functional (F) questions (0-100)
/Functional_percentile:			the percentile of the Functional Score based on normative data published in Table 3, p. 516, in Benton et al (1998)
								and linear interpolation for the gender indicated (!default is female in this script!)
									Note: for Males: the upper score reported is 97.0 (100%) and for Females it is 99.7 (100%)- in this script: anything over these scores receives a rank of 100%
									
									
									
QUESTIONNAIRE SET-UP
24 slider questions (0-100 points):
* 10 Guilt questions => the mean score is the Guilt Score
* 10 Craving questions => the mean score is the Craving Score
* 4 Functional questions => the mean score is the Functional Score

NORMS
normative data published in Benton et al (1998), p.516 (table 3);
based on N = 330 (Females: N=226; Males: N=104), 
with 
Craving: 
Female: Mean = 46.8 (SD = 21.8); Male: Mean = 29.5 (SD = 19.4)
Guilt: 
Female: Mean = 44.6 (SD = 21.8); Male: Mean = 21.2 (SD = 15.5)
Functional:
Female: Mean = 16.1 (SD = 7.3); Male: Mean = 15.6 (SD = 7.9)

percentiles reported in this script are based on the reported percentile categories and the process of linear interpolation

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.
