BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements a computerized version of the General Family Functioning Subscale (GFF-12/GFF-6) 
of the Family Assessment Device (FAD):

FAD:
Epstein, N. B., Baldwin, L. M., & Bishop, D. S. (1983). The McMaster family assessment device. Journal of Marital
and Family Therapy, 9(2), 171–180. doi:10.1111/j.1752-0606.1983.tb01497.x.

GFF-12/GFF-6:
Boterhoven de Haan, K.L. et al (2015). Reliability and Validity of a Short Version of the General Functioning Subscale 
of the McMaster Family Assessment Device. Fam Proc, 54, 116–123.
-> compares the GFF-6 (only positively worded statements) to GFF-12

___________________________________________________________________________________________________________________
OVERVIEW
___________________________________________________________________________________________________________________

GFF-12: 12 statements, rated on 4-point Likert Scales (positively and negatively worded statements)
GFF-6: 	6 statements, rated on 4-point Likert Scales (only positively worded statements)								  
	
Note: by default, this script runs the GFF-12. To run the GFF-6, go to section Editable Parameters and
change a script setting.

DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 1 minute to complete

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

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

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

q*_response:						response given (in assigned values)
									Scale: 1 (strongly agree) - 4 (strongly disagree)
									R = automatically reversed scored questions
									
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: 'generalfamilyfunctioningsubscale_summary.iqdat' (Inquisit Lab: one data file per participant)

computer.platform:				the platform the script was run on (win/mac/ios/android)
script.startdate:					date script was run
script.starttime:					time script was started
script.subjectid:					assigned subject id number
script.groupid:					assigned group id number
script.sessionid:					assigned session id number
script.elapsedtime:				time it took to run script (in ms); measured from onset to offset of script
script.completed:				0 = script was not completed (prematurely aborted); 
									1 = script was completed (all conditions run)

version:							"GFF-6" vs. "GFF-12" (depends on settings of parameters.runShortVersion)	
							
GFFScoreSum:					the sum of all 12(6) responses
								Max GFF12: 48 (the higher the score the more dysfunctional is the family perceived by participant)
								Max GFF6: 24
								
GFFScore:						the total score from 1.0-4.0 (values.GFFScoreSum divided by the number of questions)								


___________________________________________________________________________________________________________________	
INSTRUCTIONS 
___________________________________________________________________________________________________________________
can be edited under section Editable Parameters

___________________________________________________________________________________________________________________	
EDITABLE CODE 
___________________________________________________________________________________________________________________	
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 default instructions presented on each surveypage

/runShortVersion:			true (1): the GFF-6 is run
						false (0): the GFF-12 is run (default setting)
