Vulnerability Scale: a preliminary report of psychometric properties.
This work describes assessment of the psychometric properties of a self-report instrument, the Glover Vulnerability Scale. This scale was administered to a total of 11 groups (N = 695). Six of the groups were Vietnam combat veterans diagnosed as having Posttraumatic Stress Disorder (n = 531). The estimate of internal consistency was .88; the test-retest correlation over 4 wk. was .81. Convergent and discriminant validations were satisfactory based on the pattern of the scale's correlations with relevant MMPI subscales and demographic data. Scale scores also discriminated levels of functioning within the population diagnosed with Posttraumatic Stress Disorder and discriminated veterans diagnosed with Posttraumatic Stress Disorder from patients with major depressive disorder and anxiety disorder. Principal component factor analysis gave a 4-factor solution: social comfort, vulnerability, paranoia, and family trust. Over-all, the findings strongly support the clinical application of the Vulnerability Scale.
