Objective:
This study examined the prevalence and correlates of probable posttraumatic stress disorder (PTSD) in freshman entering college and prospective associations of probable PTSD with additional outcomes.
Participants:
2,310 students with data collected from Fall 2014 through Spring 2015.
Methods:
Incoming freshman completed a survey assessing for relevant variables at the beginning of fall semester and during the spring semester.
Results:
Seventy percent of the sample endorsed experiencing at least one potentially traumatic event (PTE). 34.4% of PTE exposed individuals met criteria for probable PTSD. Female sex, higher depressive and anxiety symptoms, and interpersonal PTE count were positively associated with PTSD symptoms. Higher PTSD symptoms were associated with higher anxiety and depressive symptoms, and new-onset interpersonal PTE.
Conclusions:
Identification of factors contributing to risk for PTSD is essential to inform prevention and intervention efforts. Intervention efforts should be targeted to students experiencing PTSD symptoms as they enter college.

Solid samples include a variety of substances, such as sediments from water bodies, soil, metals, and biological tissues. Two standard methods for extracting sediments from water bodies are grab sampling and piston coring. Grab sampling involves using a device to collect a discrete sediment sample from the bottom of a water body with minimal disturbance. Grab samples do not always represent the entire area due to...

Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...
