CCK Impulsivity Scale Validation

To develop a valid measure of the personality trait impulsivity, four dimensions of the trait were identified through a literature analysis; these dimensions were Sensation Seeking, Lack of Premeditation, Lack of Perseverance, and Urgency. Items based upon these dimensions were then developed and used to build a scale. To test the validity of the scale, henceforth known as the CCK scale, the scale was administered to 40 college students, of whom 32 scales were included in the analysis, concurrently with the BIS-11, a prevalidated impulsivity scale. By evaluating the correlation between the scores on the two scales, the validity of the CCK scale was determined by its validity coefficient. The analysis revealed a strong correlation between the two, r(30)=.826, p=6.07 E-8. The relationship between the CCK and the BIS-11 was significant, thus there is considerable evidence for the validity of the CCK.
