Construction and Validation of a Scale for the Measurement of Reality Distortion

This research project was aimed at construction and validation of a short scale for the measurement of reality distortion. Factor analysis of the data derived from administration of a preliminary scale to a sample of Shahid Chamran University undergraduate students (Ahvaz, Iran) yielded a 10-item scale entitled Ahvaz Reality Distortion inventory (ARDI). The test-retest reliability and internal consistency coefficients of ARDI were found to be satisfactory. Validation of ARDI was assessed by its concurrent administration with Marlowe- Crowneʹs Social Desirability Scale, a construct definition of reality distortion, and three Lie Sub-Scales derived from Mini-Mult MMP1., Eysenck Personality Questionnaire, and Coopersmith Self-Esteem Scale. Results indicate that psychometric characteristics of ARDI are very satisfactory, and thus could be employed as a reliable and valid self-report inventory for measuring reality distortion.
