Perceived discrimination is assessed with a 9 items based on a previously established scale. The scale assesses the subjective experience of being treated unfairly in common everyday situations. Items are framed in the context of general mistreatment without reference to race, age, or gender.
Participants are asked to rate how often they experienced nine instances of discrimination on a 4-point scale (see table below). Responses are then dichotomized (often or sometimes = 1 and rarely or never = 0) and summed across all items for each participant. The total score ranges from 0 to 9, with higher scores indicating more discrimination.
Participants are presented the following items:
Response choices for each item:
Response | Response code | Calculated value |
---|---|---|
Often | 1 | 1 |
Sometimes | 2 | 1 |
Rarely | 3 | 0 |
Never | 4 | 0 |
Note: In preliminary analysis, the Cronback coefficient alpha, an indicator of internal consistency reliability, was 0.8.
