BACKGROUND INFO 	
___________________________________________________________________________________________________________________	

This script implements the 9-item Social Media Disorder Scale by Van Den Eijnden et al (2016).

OVERVIEW
___________________________________________________________________________________________________________________	

The scale consists of 9 items, one for each of the following 9 problem areas:

Preoccupation: … regularly found that you can't think of anything else but the moment that you will be able to use social media again?
Tolerance: … regularly felt dissatisfied because you wanted to spend more time on social media?
Withdrawal: … often felt bad when you could not use social media?
Persistence: … tried to spend less time on social media, but failed?
Displacement: … regularly neglected other activities (e.g. hobbies, sport) because you wanted to use social media?
Problem: … regularly had arguments with others because of your social media use?
Deception: … regularly lied to your parents or friends about the amount of time you spend on social media?
Escape: … often used social media to escape from negative feelings?
Conflict: … had serious conflict with your parents, brother(s) or sister(s) because of your social media use?

(Note: these are the 9 areas assessed to diagnose 'Internet Gaming Disorder' according to the DSM-V.
Van Den Eijnden et al (2016) argue that the same problem areas should be assessed for the related Social Media Disorder
as they can both be considered forms of 'Internet addictions'.)


Each question is answered on a yes/no scale.

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

(1) Raw data file: 'smd.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: yes (1) - no (0)
									
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: 'smd_summary.iqdat' (Inquisit Lab: one data file per participant)

computer.platform:					the platform the script was run on (win/mac/ios/android)
inquisit.build:						the version/build of Inquisit
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.smd_totalscore:			sums up the responses to the 9 items (Range: 0-9)
									A score of 5 or higher is seen as indicative of fulfilling
									a formal diagnosis of Social Media Disorder (Van Den Eijnden et al (2016, p.479))


+ responses to the individual 9 items
