Evaluating and developing a multidimensional, dispositional measure of appraisal.

Although theories of stress have emphasized the critical role of the appraisal process, the use of dispositional measures of appraisal have not been readily investigated. Using a large multiethnic sample, we examined the factorial validity and dimensionality of a dispositional version of the Stress Appraisal Measure (SAM; Peacock & Wong, 1990). Both exploratory and confirmatory factor analyses resulted in a 4-factor representation of dispositional appraisal fitting better than its originally proposed 6-factor representation. This 4-factor model was invariant across gender groups. Although the 6-factor model purported to measure 3 dimensions of primary appraisal and 3 dimensions of secondary appraisal, these factors were found to be highly unstable and had questionable internal consistency. In contrast, the more parsimonious 4-factor solution identified 4 relative distinct and reliable scales of appraisal: 3 primary (Challenge, Threat, and Centrality) and 1 secondary (Resources). These findings suggest that meaningful dispositional dimensions of appraisal can be derived and incorporated into trait-state models of the stress process.
