Generalized Anxiety Disorder Scale—Revised

GADS-R measures the role of metacognitions in relation to generalized anxiety. Two of the factors measured by the questionnaire are particularly relevant to this study: (1) Positive metacognitive beliefs, which indicates to what degree the respondent believes that deliberate thinking is useful; (2) Negative metacognitive beliefs, which indicates the degree to which the respondent believes that deliberate thinking/worry is uncontrollable and physically dangerous. Additionally, the degree of avoidance and use of coping strategies was measured using the same scale (27). Of the GADS-R, weekly time spent worrying is measured on scale from 0 (“no time”) to 8 (“all the time”); how often 9 coping behaviors and 6 avoidance behaviors are enacted in a week are measured on the same scale from 0 to 8 and summed; negative and positive metacognitive beliefs related to worry are measured on a scale from 0 (“I do not believe this at all”) to 100 (“I'm completely convinced this is true”).
