[The reliability and validity of the children's negative cognitive errors questionnaire].
OBJECTIVE
The Children's Negative Cognitive Errors Questionnaire (CNCEQ) is a self-report scale measuring negative cognitive errors in children. The aim of this study was to examine its reliability and validity, and to obtain its norms for Turkish children.


METHODS
The study was carried out at 3 public schools representing 3 different socioeconomic statuses. The sample of 538 children was selected randomly among third-eighth grade elementary school students. The students were evaluated by the CNCEQ, Children Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Coopersmith Self-Esteem Inventory (SEI). For test-retest reliability, the CNCEQ was readministered to the students 7 days after its first administration.


RESULTS
In the reliability analysis, the Cronbach's alpha coefficient was calculated as 0.82 and 0.79. Test-retest reliability of the total score was 0.87. In comparing the CNCEQ to CDI, SAIC, TAIC, and SEI, correlations were r = 0.77, r = 0.57, r = 0.50, and r = -0.65, respectively (P < 0.001). Construct validity factors had eiganvalues > 1. These factors were related to catastrophizing, personalizing, and selective abstraction.


CONCLUSIONS
The Turkish version of the CNCEQ has appropriate reliability and validity for assessing negative cognitive errors in Turkish children; however, additional reliability and validity studies should include patient groups with specific disorders.
