Note: PTSD=posttraumatic stress disorder.

^aModels were estimated using discrete-time survival analysis with person-years as the unit of analysis. Only respondents with lifetime PTSD were included in the analysis.

^bPoverty was defined using household family income for the past-year relative to the federally defined poverty line based on family size. Poverty was defined as less than three times the poverty line and low poverty (reference group) as 3 or more times the poverty level.

^cVariables represent counts of fear, distress, behavior, substance, and bipolar disorders with onsets prior to occurrence of respondents’ self-reported worst PTE.

^dVariables represent worst event type: interpersonal violence, accidents, network/witnessing, and other PTEs.

^eVariables represent counts of PTEs occurring prior to respondents’ self-reported worst event within each of the four PTE categories: interpersonal violence, accidents, network/witnessing, and other PTEs.

^fVariables represent counts of PTEs occurring after the respondents’ self-reported worst event within each of the four PTE categories: interpersonal violence, accidents, network/witnessing, and other PTEs.
