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

and Family Therapy, 9(2), 171–180. doi:10.1111/j.1752-0606.1983.tb01497.x.

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)
12 individual responses

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)
