BACKGROUND INFO 	
___________________________________________________________________________________________________________________
This script implements a computerized adaptation of the short form of the Mindful Attention Awareness Scale (MAAS) as described in:

Brown, K.W. & Ryan, R.M. (2003). The benefits of being present: Mindfulness and its role in psychological well-being. 
Journal of Personality and Social Psychology, 84, 822-848.

Carlson, L.E. & Brown, K.W. (2005). Validation of the Mindful Attention Awareness Scale in a cancer population.
Journal of Psychosomatic Research, 58, 29-33.

OVERVIEW
___________________________________________________________________________________________________________________
											  
The trait MAAS is a 15-item scale designed to assess a core characteristic of mindfulness, namely, 
a receptive state of mind in which attention, 
informed by a sensitive awareness of what is occurring in the present, simply observes what is taking place.

Participants are asked to answer 15 6-point Likert-type questions with the following anchors:
"almost always", "very frequently", "somewhat frequently", "somewhat infrequently", "very infrequently" and "almost never".

Scoring: To score the scale, simply compute a mean (average) of the 15 items.

DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 2 minutes to complete

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

(1) Raw data file: 'maas_survey*.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 (almost always) - 6 (almost never)
									no 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: 'maas_summary*.iqdat' (a separate file for each 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)
								
expressions.maas_mean			mean of responses to the 15 6-point questions

can be edited under section Editable Parameters.
The original instructions are:
"Below is a collection of statements about your everyday experience. Using the 1-6 scale below, please indicate how frequently or infrequently 
you currently have each experience. Please answer according to what really reflects your experience rather than what you think your
experience should be. Please treat each item separately from every other item."

to further customize your experiment.
