Abstract
The PANAS Scales of Positive and Negative Affect: Factor Analytic Validation and Cross-cultural Convergence. Recent evidence suggests that the structure of mood is composed of two dominant and relatively independent dimensions, i.e., positive and negative affect. Such dimensions have consistently emerged as the first two factors in factor analyses (orthogonal or oblique solutions). The Positive and Negative Affect Schedule (PANAS; Watson, Clark y Tellegen, 1988a), a 20-item self-report questionnaire, is one of the most widely used measure of affectivity and has been reported to have excelent psychometric properties with U.S. samples. This study investigated the structure of mood, as well as factorial validity of the Spanish version of the PANAS, in a sample of 712 undergraduates in Madrid. Using exploratory and confirmatory factor analytic techniques (EQS), the autores tested the PANAS structure as well as the two-factor model of mood, and examined gender differences. Results revealed a robust and stable two-dimensional structure (positive and negative affect), and provide strong support to construct validity, reliability (internal consistency) and cross-cultural validation of the Spanish PANAS.
