2.2.8. The metacognitions Questionnaire 30 (Wells & Cartwright-Hatton, 2004)

The MCQ-30 is a 30-item measure that assesses metacognitions. The MCQ-30 has five factors: positive beliefs about worry; (ii) negative beliefs about thoughts concerning uncontrollability and danger; (iii) cognitive confidence; (iv) beliefs about the need to control thoughts; and (v) cognitive self-consciousness. Responses are based on the following 4-point Likert-style scoring: 1 (do not agree) to 4 (agree very much). Higher scores indicate higher levels of maladaptive metacognitions. The MCQ-30 has demonstrated good internal consistency and convergent validity and has acceptable test–retest reliability (Spada et al., 2008, Wells and Cartwright-Hatton, 2004). The Persian MCQ-30 was used in the present study. This measure has been shown to have acceptable internal consistency (Cronbach's alpha = 0.73), test–retest reliability (ICC = 0.73) and acceptable validity (Shirinzadeh, Goudarzi, RAHIMI, & Naziri, 2009). Also, Cronbach’s alpha coefficients of all subscales range between 0.59 and 0.87 (Shirinzadeh et al., 2009).
