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.
