Reliability and validity of the Turkish version of the Automatic Thoughts Questionnaire.

The present study investigated the reliability and validity of the ATQ in the Turkish cultural context. It is hoped that with this type of cross-cultural information, the universality of the proposed cognitive constructs can be advocated more reliably. The subjects were 345 university students; the split-half reliability of the ATQ was found to be r = .91 and Cronbach's alpha was .93; and item/total correlations ranged between .36 and .69. The Turkish ATQ correlated well with the BDI (r = .75), and it discriminated successfully between the symptomatic and asymptomatic groups. Factor analysis revealed five factors that were similar to those found in American samples. Nevertheless, some differences were noticed in the relative strength of the factors and in the distribution of items into factor clusters.
