Assessing negative cognitive style: Development and validation of a Short-Form version of the Cognitive Style Questionnaire

► We developed a Short-Form version of the Cognitive Style Questionnaire (CSQ). ► The CSQ Short Form (CSQ-SF) demonstrated satisfactory internal reliability. ► Test-retest reliability was also satisfactory. ► Scores demonstrated predicted correlations with measures of depression and anxiety. ► The CSQ-SF may be a useful research tool in assessing vulnerability to depression.
