e in my family said hurtful or insulting things to me." Responses to these five items were averaged to create a single scale score (alpha = 0.87). This variable then was log-transformed to improve normality, and standardized to improve interpretability. Childhood sexual trauma was measured using a single item at baseline taken from the Deployment Risk and Resilience Inventory (DRRI; [@B25]). Childhood sexual trauma (CST) was defined as an affirmative response to the following item: "\[Prior to age 18\] I experienced unwanted sexual activity as a result of force, threat of harm, or manipulation."

Military experiences {#S2h}
--------------------

Military experiences during deployment (D) and post-deployment (PD) were also measured using the DRRI. For this analysis, the following scales were included: military preparation (D), deployment environment (D), unit support (D), unit relationships (D), combat experiences (D), social support after deployment (PD), and post-deployment stressors (PD). The scales that applied during deployment were measured at baseline only, and the scales for post-deployment experiences were assessed at baseline, 3 months, and 6 months.

Television and Internet usage {#S2i}
-----------------------------

Respondents were asked how many hours per day they watched television, and how many hours per week they used the Internet, at baseline, 3 months, and 6 months. Responses were categorized based on tertiles for both items. For television use, this resulted in the following categories: 0--1, 1--2, and \>2 hours per day. For Internet use, the categories were: \<7, 7--14, and \>14 hours per week.

Statistical analysis {#S2j}
--------------------

All analyses were conducted using Stata Statistical Software version 13.0. First, we descriptively examined differences between those with and without CSB. We determined the significance of differences for all sociodemographic variables, potential risk factors, and potential protective factors using *t*-tests and chi-square tests of independence. Given
