Self-Perception of Prejudice and Discrimination Scale: Evidence of Validity and Other Psychometric Properties

The self-perception of prejudice and discrimination (SPPD) is a global assessment of the degree to which individuals see themselves as the target of negative attitudes and behaviors because of their social group. This study sought to create a scale to measure SPPD. Evidence of validity was sought based on content, structure, and relationships with other variables. The scale was applied to 571 adults strongly identified with their social groups. A single-factor structure was found, with satisfactory internal consistency and adequate discrimination and threshold parameters. Correlations with other variables were found as theoretically expected. For example, SPPD correlated positively with neuroticism and negatively with belief in a just world. Finally, we found that people from groups with low social status had higher levels of SPPD compared to groups with high social status. The set of evidence shows a different-groups-oriented short-form scale with satisfactory psychometric properties to measure SPPD.
