Note. Results are based on domain-specific analyses. The variables listed were selected from those that were statistically significant after adjustment for site of emergency department care and other variables in the domain. Owing to missing data, sample sizes for some variables do not sum to the total number of participants; percentages shown are based on the numbers of women with available data. An interaction with site of emergency department care was detected for 1 variable not shown: “lives with extended family or acquaintances/friends” exclusive of nuclear family member or intimate partner. Also not shown are 2 medical history variables, asthma and abdominal pain, that were inversely associated with intentional injury, after adjustment for site of emergency department care.
aA score of less than 30 was considered to indicate low self-esteem. A score between 30 and 37 was considered midrange self-esteem, and a score greater then 37 was considered high self-esteem.
