خلاصه	The Intergroup Contact Scale measures the quantity and quality of face-to-face interaction between members of different social groups (racial, ethnic, religious, national, or other categories). Rooted in Gordon Allport's contact hypothesis (1954), which proposed that prejudice decreases when groups interact under favorable conditions, the scale is fundamental in research on prejudice reduction, integration, and intergroup relations.	The Generalized Trust Scale measures an individual's propensity to trust people in general, particularly strangers with whom they have no direct relationship. Originally developed by Morris Rosenberg in 1956 and later refined by Toshio Yamagishi and colleagues, it has become foundational in research on social capital, civic participation, and intergroup relations.
