A Study of Factor Structur, Validity and Reliabileaty of Pro-social Tendencies Measure Revised Questionnaire Among University Students

The purpose of this study is to examine the validity and reliability of pro-social tendencies scale among students at the university of Isfahan. The population in this study compised whole undergraduate students of the university of Isfahan in the educational year 1387-88. By using a simple randomized sampling commensurate with Cohen & others (2000) formula, some 300 subjects were selected. Scales used concurrently were: Carlo et alʹs pro-social tendencies (with 25 items), Rushton et alʹs global pro-social behavior (with 20 items), Davisʹ empathic concern (with 7 items), Nickell et alʹs altruistic Values (with 4 items) and Steele et alʹs Social responsibility motivation (with 4 items). All of the above scales were administered concurrently for studying the validity and reliability of pro-social tendencies. Data was analyzed and studied using coronbachʹs Alpha, Spearman-Brown and Guttmanʹs coefficients, factor analysis (with principal component and varimax rotation) and concurrent validity (the correlation between scales). Results showed that the coronbachʹs Alpha for pro-social tendencies, global pro-social behavior, empathic concern, altruistic values and social responsibility motivation were 0.861, 0.845, 0.600, 0.500 and 0.782 respectively. The result of factor analysis showed five factors for pro-social tendencies: anonymouse, public-altruistic, emotional, dire and compliant pro-social behaviors.
