The Affective Neuroscience Personality Scales (ANPS) in Slovenia: Validation of the Six Primary Scales Across Three ANPS Versions

Abstract

Abstract To assess primary emotions in subcortical brain regions across all mammals, the affective neuroscience personality scales (ANPS) were created for use in research involving human subjects. Later revisions of the scales have been validated across many countries and are used in diverse fields of psychology. The ANPS revisions culminated in the most recent ANPS 3.1. In this study, we evaluated the psychometric properties of the ANPS 3.1 and its two abbreviated versions (affective neuroscience personality scales – brief (BANPS) and affective neuroscience personality scales – short version (ANPS-S)) in a Slovenian community sample of 502 young adults. We simultaneously examined several kinds of validity evidence across the three versions: construct validity, internal reliability, and convergent validity. Our findings revealed acceptable construct validity of the six-factor model of the BANPS that was superior to the ANPS-S and particularly to the ANPS 3.1. The latter exhibited incremental fit issues noted in previous versions. However, we revealed sufficient internal reliability and convergent validity of the scale scores against the Big Five personality traits, and the frequency of the participants’ recently felt positive and negative emotions across all three ANPS versions. Testing the measurement invariance of BANPS across sex suggested full metric invariance and partial scalar invariance which allows direct score comparisons between males and females.
