BACKGROUND INFO 	
___________________________________________________________________________________________________________________	

This script implements a computerized version of the Short Form of the Metacognitions Questionnaire (MCQ-30) 
as described in:

Wells, A., & Cartwright-Hatton, S. (2004). A short form of the metacognitions questionnaire:
Properties of the MCQ-30. Behaviour Research and Therapy, 42(4), 385-396. doi:10.1016/S0005-7967(03)00147-5

Long Form of the Metacognitions Questionnaire (MCQ):

questionnaire and its correlates. Journal of Anxiety Disorders, 11, 279–296.

OVERVIEW
___________________________________________________________________________________________________________________	
30 4-point likert scale, self-report

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 3 minutes to complete

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

(1) Raw data file: 'mcq_30_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 (do not agree) - 4 (agree very much)
									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: 'mcq_30_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)

Score Interpretation: higher scores => higher levels of unhelpful metacognition

expressions.Total:	sum of all responses (score range: 30-120)
expressions.zTotal: z-score of Total Score with Mean = 48.41, SD = 13.31 (see Wells & Cartwright-Hatton, 2004, Table 1, p.389)
expressions.pTotal: percentile rank of z-score

Subscales are calculated by summing the following items (score range: 6-24): 

expressions.cognitiveConfidence (lack of)= sum of (q8,q14,q17,q24,q26,q29)
expressions.zCognitiveConfidence: z-score with Mean = 9.51, SD = 4.06 (see Wells & Cartwright-Hatton, 2004, Table 1, p.389)
expressions.pCognitiveConfidence: percentile rank of z-score

expressions.positiveBeliefs (about worry)=sum of (q1,q7,q10,q19,q23,q28)
expressions.zPositiveBeliefs: z-score with Mean = 9.60, SD = 3.46 (see Wells & Cartwright-Hatton, 2004, Table 1, p.389)
expressions.pPositiveBeliefs: percentile rank of z-score

expressions.cognitiveSelfConsciousness = sum of (q3,q5,q12,q16,q18,q30)
expressions.zCognitiveSelfConsciousness: z-score with Mean 11.65, SD = 4.68 (see Wells & Cartwright-Hatton, 2004, Table 1, p.389)
expressions.pCognitiveSelfConsciousness: percentile rank of z-score

expressions.uncontrollabilityDanger (negative beliefs about) = sum of (q2,q4,q9,q11,q15,q21)
expressions.zUncontrollabilityDanger: z-score with Mean = 9.30, SD = 4.00 (see Wells & Cartwright-Hatton, 2004, Table 1, p.389)
expressions.pUncontrollabilityDanger: percentile rank of z-score

expressions.needControlThoughts = sum of (q6,q13,q20,q22,q25,q27)
expressions.zNeedControlThoughts: z-score with Mean = 8.34, SD = 2.62 (see Wells & Cartwright-Hatton, 2004, Table 1, p.389)
expressions.pNeedControlThoughts: percentile rank of z-score
