  • attitudes
  • This study extends prior research by longitudinally testing these associations across racial/ethnic groups and investigating whether culturally relevant variations within racial/ethnic minority groups, such as skin tone (i.e., lightness/darkness of skin color), are linked to attitudes toward marriage and cohabitation and sex.
