Compares how well two major BIS/BAS-based questionnaires capture Gray–Wilson personality constructs and their construct validity.
This article evaluates whether the Gray–Wilson Personality Questionnaire and the BIS/BAS scales measure the same underlying reinforcement-sensitivity constructs in a valid way. By directly comparing their construct validity, it clarifies how different operationalizations of BIS/BAS-related traits align or diverge. The work helps researchers choose between instruments (or interpret findings across them) when studying approach/avoidance motivation and related personality differences. Its implications are mainly methodological: conclusions about motivation-related traits can depend on the questionnaire used.
Psychometric comparison of two personality questionnaires focused on construct validity.
