Construct Validation of a Revised Strain-Free Negative Affectivity Scale
Based on research demonstrating that many extant measures of negative affectivity (NA) are contaminated with strain contents Fortunato and Stone-Romero developed the Strain-Free Negative Affectivity Scale (SFNA). However, because of several psychometric concerns involving scores on the original scale, a revision of the SFNA was undertaken. The SFNA-Revised (R) was administered to two samples of participants, along with instruments purportedly measuring neuroticism, negative emotionality, trait negative affect, affect intensity, affective disposition, extroversion, and positive affectivity. Estimates of reliability and factor analytic findings indicate that scores on the SFNA-R exhibited better psychometric properties than scores on the original scale. In addition, evidence for the construct validity of scores on the SFNA-R is presented. Based on the above, the authors conclude that the SFNA-R is a worthy alternative to extant measures of NA.
