BACKGROUND INFO

											*Purpose*
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):

Cartwright-Hatton, S., & Wells, A. (1997). Beliefs about worry and intrusions: the metacognitions questionnaire and
its correlates. Journal of Anxiety Disorders, 11, 279–296.


											  *Task*
30 4-point likert scale, self-report


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

(1) Raw data file: 'MCQ_30_survey.iqdat'

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

q*_response:					response given (in assigned values)
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)

script.startdate:				date script was run
script.starttime:				time script was started
script.subjectid:				subject id number
script.groupid:					group id number
script.elapsedtime:				time it took to run script (in ms)
computer.platform:				the platform the script was run on
/completed:						0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run)

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

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

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

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

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

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

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

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