Psychometric Properties of the Wolpe-Lazarus Assertiveness Scale with Community-Dwelling Older Adults
Journal of Psychopathology and Behavioral Assessment
The psychometric properties of the Wolpe-Lazarus Assertiveness Scale (WLAS) were examined with an older community-dwelling, nonclinical, adult population. Three hundred twenty-seven older adults (ages, 57–96; mean, 75.68) who were not psychiatrically impaired completed a demographic questionnaire and the WLAS. Fifty-seven of the 327 subjects also filled out the WLAS on a repeated basis after 3 or 4 weeks in order to determine the test-retest reliability. Results indicate that the WLAS has an adequate internal consistency (Cronbach'sα=.75) and test-retest reliability (r=.81). WLAS cutoff scores of 14 and under identify unassertiveness. Older adults who are (1) African-American or (2) of lower SES tend to be significantly less assertive. Also, five factors emerged from a principal-components analysis accounting for 34.7% of the total variance.
