Abstract
Aim:The Aim of this research was studding the psychometric properties of self-handicapping scale as a suitable tool for measuring the self-handicapping.Method:The population was all of Tehran’s university students that 520 people were selected as a sample from the universities of AllamehTabataba’i, Tehran, south branch of Payam-e-Noor & south branch of Islamic Azad University in various fields through purposive sampling. The research tool wasself-handicapping scale (Jones, &Rhodewalt 1982).For studding the psychometric properties of self-handicapping was determined the content validity, construct validity and reliability of this scale.Results:The content validity of this scale was confirmed by 5specialists. In exploratory factor analyze supported three factor solution. Confirmatory factor analysis results indicated that the three-factor model fit the data. Internal consistency of the factors and scale was quite high and also item analysis showed high internal consistency between the items and scale. The reliability of scale was obtained 0.918 using the Cronbach'salpha method and 0.767 using the spilt-half method. Conclusion:Self-handicapping scale has good psychometric properties for college Students. Reliability of this scale was very high and Three-factor model proposed in the research has good construct validity and Helps researchers that can using this instrument for measuring the self-handicapping in the college students.
