The BIAS-Treatment Scale (BIAS-TS): a measure of the subjective experience of active and passive harm and facilitation

This article describes the Behaviors from Intergroup Affect and Stereotypes-Treatment Scale (BIAS-TS), a self-report measure of experiences of active harm, passive harm, active facilitation, and passive facilitation. The BIAS-TS was derived from the Behaviors from Intergroup Affect and Stereotypes (BIAS) Map, and provided reliable, replicable, and stable indexes of different harmful and facilitatory behaviors that people encounter in their day-to-day lives from multiple sources (Studies 1 and 2). The BIAS-TS subscales were uniquely associated with concurrent subjective well-being, and were distinct from the HEXACO dimensions of personality, Social Dominance Orientation, and Right-Wing Authoritarianism (Study 3). The BIAS-TS also provided novel support for the subordinate-male target hypothesis proposed by social dominance theory (Study 4). The BIAS-TS instruction set can be easily reworded to assess perceived discrimination and intergroup rejection from specific or multiple general sources and is applicable in numerous contexts. A copy of the BIAS-TS is included.
