ABBREVIATIONS: SE = standard error (omitted for dummy variables); SES = socioeconomic status.

^aMeans for dummy variables can be interpreted as the proportion of the sample coded 1 on that indicator.

^bAll analyses are weighted and corrected for survey design.

^cStatistically significant difference (p < .05) between nonvictims and victims.

^dUnweighted N.
