A multitrait-multimethod approach to the validation of affect constructs
It has been debated about the structure of affect for a long time. Some researchers claim that positive affect (PA) and negative affect (NA) are unipolar dimensions that can be experienced simultaneously and independently. Others state that affect is bipolar suggesting that PA and NA are opposite poles of one single dimension. Such conclusions are derived from empirical studies of affect dimensionality that have two major limitations: the cross-sectional design and the measurement of affect constructs with a single assessment method. The multitrait-multimethod (MTMM) approach developed by Campbell and Fiske (1959) was used in the present study to clarify the issue about the convergent and discriminant validity of NA and PA. Participants (224 psychology students) completed a measure of PA and NA using three different response formats (dichotomous, frequency and extent format) which represented three different methods. A confirmatory factor analysis of affects’ 2 x 3 multitrait-multimethod matrix was performed using the correlated uniqueness model approach. The best fitted MTMM model showed a negative and weak correlation between the latent positive affect and negative affect traits when controlled for systematic error variance due to specific response formats, which support the discriminant validity of these constructs. The same model showed large trait factor loadings revealing strong associations of PA and NA indicators to their purported latent constructs providing evidence for convergent validity.
