^**. Correlation is significant at the 0.01 level (2-tailed).

^*. Correlation is significant at the 0.05 level (2-tailed).

Participants are adolescents from Connecticut who were surveyed in 2015.

Correlations among race variables are not available, as these categories are mutually exclusive.

Ns ranged from 1,643 to 2,273 for variables that are mutually exclusive (i.e. race variables).

Ns range from 2,761 and 3,473 for variables that are not mutually exclusive.
