The Rating Scale of Social Ability: Development, and Testing of Reliability and Validity

Objective: To develop a Rating Scale of Social Ability (RSSA) and to test its reliability and validity. Methods: The reliability and validity of RSSA were examined the basis of on 1605 normal subjects (814 males and 791 females) from 5 districts of China. Results: The Cronbach's α coefficients of RSSA were 0.88~0.92, the split-half reliability were 0.79~0.89, the test-retest reliability ranged from 0.67~0.86, and the scorer reliability were 0.91~0.97. The correlations between item scores and the total scores ranged from 0.49 to 0.80, and the correlations between the factor scores and composites were 0.76~0.89. The construct validity was supported by factor analysis. Acceptable internal consistency was obtained for total and dimensional scores. Significant correlation was found between the total scores of RSSA and the scores of practice ability, and medium correlation with IQ of WAIS-RC. Conclusion: RSSA has acceptable psychometrics properties on reliability and validity.
