Abstract: | The psychometric properties of the Wolpe-Lazarus Assertiveness Scale (WLAS) were evaluated with a sample of 100 male and 157 female psychiatric patients. There were no significant differences with regard to males and females for total WLAS scores. The WLAS seems to be internally consistent and has acceptable split-half and test-retest reliabilities. A factor analysis performed separately for males and females indicates that the 10 most prominent factors account for about 60% of the accumulated variance. The primary factor, shared by males and females, was labeled General Expressiveness. There was little evidence for the external validity of the WLAS when total scores were correlated with performance on a role play test. However, when WLAS factor scores were evaluated in light of role played performance, somewhat better evidence of the external validity of the WLAS was found in two of the factors for the females. |
