An examination of the discriminant validity of the Strain-Free Negative Affectivity scale

This study reports evidence supporting the discriminant validity of the Str ain-Free Negative Affectivity (SFNA) scale (Fortunato & Stone-Romero, 1999) . Stressor-strain correlations controlling for neuroticism and negative emo tional reactivity (NER), both considered markers of negative affectivity (N A), were examined using partial correlation and latent variable procedures. Support was found for the authors' hypothesis that correlations between se lf-reports of work-related stressors and physiological and psychological st rain would be attenuated to a much greater degree when neuroticism was cont rolled than. when NER was controlled. Thus the SFNA is a viable measure of NA, especially for research examining stresser-strain relations.
