Psychometric properties of the Metacognitions Questionnaire-30 (MCQ-30) in a Greek sample

Background The term Metacognition refers to the psychological processes that are involved in the way a person controls, modifies, and appraises his own thoughts [1]. Maladaptive metacognitions have been related to the development and maintenance of psychological disorder [2,3]. The Metacognitions Questionnaire-30 (MCQ-30) is a multidimensional instrument for assessing metacognitions, composed of five factors: cognitive confidence, positive beliefs about worry, cognitive self consciousness, negative beliefs about worry and need to control thoughts [4]. Psychometric properties of the MCQ-30 have been well documented [4] suggesting that it is a valid instrument that has already been used in clinical research with several psychiatric disorders.
