Pilot Study of Reliability and Validity of Causal Dimension Scale

This research was conducted to evaluate the validity and reliability of three common methods of causal dimension: causal dimension scale, causal important rating, and open – ended attributions. Research's data were gathered from 147 university students that volunteered for this study. The data were analyzed using Cranach’s alpha, Pearson correlation coefficient, and confirmatory factor analysis for evaluation of discriminate validity, construct validity, and reliability of attribution scales. Results showed that in spite of problems in controllability subscale, Causal Dimension Scale generally has high validity and reliability in comparison with other causal dimension measurements. It is recommended for researchers to use the Causal Dimension Assessment Scales in attribution researches to measure the attributer perception of own causal attribution.
