Clinical utility of the Primary Care--PTSD Screen among U.S. veterans who served since September 11, 2001.

Posttraumatic stress disorder (PTSD) is a prevalent anxiety disorder that is often undetected among primary care patients. The Department of Veterans Affairs has implemented the Primary Care-PTSD Screen (PC-PTSD) to screen for PTSD; however, minimal research has examined its utility. This study was designed to assess the diagnostic accuracy of the PC-PTSD among veterans who had served since 9/11/2001, including operations in Afghanistan (Operation Enduring Freedom) and Iraq (Operation Iraqi Freedom).

Effect of children's perceived rejection on physical aggression.

This study investigated whether the perception of self as socially rejected might contribute to increased physical aggression among elementary-school children. It was hypothesized that physically aggressive children would become more physically aggressive over time if they perceived that they were rejected and tended to blame peers for social failure experiences. Third-grade boys and girls (n = 941) were assessed in the Fall and Spring of the school year.
