Abstract

The purposes of this research were to study item wording (positive/negative) and response order (ascending/descending) affecting mean scores of personality inventory, item wording (positive/negative) and response order (ascending/descending) affecting reliability of personality inventory, item wording (positive/negative) and response order (ascending/descending) affecting factor structure of personality inventory and interaction effects between item wording (positive/negative) and response order (ascending/ descending) to mean score of personality inventory. Subjects in this study were 1,261 undergraduate students. Questionnaires were used as a research instrument. Statistics analyzed were percentage, mean, standard deviation, t-test, Two-way ANOVA, internal consistency, Factor Analysis, Comparison of internal consistency from independent samples by Feldt method and Tucker’s consistency coefficient. Results found that item wording (positive and negative) affecting mean scores of some factors (openness to experience and extraversion) of personality inventory, item wording (positive and negative) affecting reliability of some factors (openness to experience, conscientiousness and neuroticism) and response order (ascending and descending) scale affecting reliability of only one factor of personality inventory (agreeableness), item wording (positive/negative) and response order (ascending/descending) had no affect to factor structure of personality inventory and there was no interaction effects between item wording (positive/negative) and response order (ascending/descending).
