Although there are a number of measures designed to assess the cognitive appraisal of stress in adult populations, currently there are no measures that are specifically designed to assess this important construct in adolescents. To overcome this limitation, the factorial validity and dimensionality of a dispositional measure of stress appraisal was examined in the current study. Using a multiethnic adolescent sample, both exploratory and confirmatory factor analyses resulted in a three-factor representation of appraisal. The three factors included two primary appraisal dimensions (Threat and Challenge) and one secondary appraisal dimension (Resources). This three-factor model, however, is inconsistent with four- and six-factor models found previously in adult samples. Thus, these findings suggest that the cognitive appraisals made by adolescents are less complex or differentiated than those of adults. Moreover, these findings suggest that dispositional measures are relevant for adolescent samples and should be incorporated into stress and coping paradigms.
