Objectives: The aim of the present research was to examine the validity, reliability and factor structure of Wells and Davis Thought Control Questionnaire (TCQ). Method: In this descriptive study, 472 undergraduate students of Urmia University were randomly selected, and the ques-tionnaire was administered to them. Cronbach’s alpha factor and confirmatory factor analysis (CFA) were used in order to determine the reliability and validity of T‍‍CQ. One and two factor model of TCQ was examined using the latter method. Results: Reliability coefficients for TCQ five factors were between 0.62 and 0.73, which indicate a relatively low reliability. Results of Confirmatory Factor Analysis indicated that worry and self-punishment load on one factor and reevaluation, distraction and social strategies load on the other. Therefore, the questionnaire encompasses and evaluates both the functional and dysfunctional strategies. Chi-square of goodness of fit model obtained two factors (651.82), which is smaller compared with a factor model (1169.10) and therefore considered a suitable model.  Other goodness of fit indices such as GFI (0.91), AGFI (0.88), AIC (445.87), CFI (0.90) and NNFI (0.95) were also closer in terms of amount to relevant standard indices. Conclusion: The obtained results replicated some of the previous findings and supported the TCQ two-factorial structure as well as the super-order factor model in which TCQ is composed of two factors and five components. However, because of insignificant factorial load of some items as well as the relatively low reliability of indices, the authors suggest that TCQ should be revised.
