Principal components factor analysis of TCQ revealed five factors named"Distraction", "Worry", "Social control", "Punishment" and "reappraisal". Distraction was negatively associated with Depression, anxiety, physical symptoms and problems in interpersonal relationships. Punishment and worry subscales related positively withBDI-II, BAI and all scales of GHQ. Factor analysis of AnTI showed three factor solution named "meta-worry", "health worry" and "social worry".

These results provide promising evidences about utility of Persianversion of TCQ and AnTI in Iranian population. However, further research is required to assess psychometric properties of TCQ and AnTI among Iranian patients with Depression and Anxiety disorders.
