Self-reported health profiles of trauma victims with and without psychiatric histories.

Background: This study examined associations between self-reported trauma exposure and physical health status after control of variance associated with psychiatric disturbance. Physical and mental health diagnoses were examined among participants with and without histories of trauma and post-traumatic stress disorder (PTSD).

Participants And Procedure: College ( = 2,320) and national ( = 663) respondents were surveyed to identify trauma histories defined using the primary DSM-5 diagnostic criterion for PTSD.

The missing piece in block design tasks: Resolving performance differences elicited by designs with identical stimulus parameters.

Block design stimulus variables (perceptual cohesiveness, response uncertainty, partial components) have been previously shown to impact test performance. However, relevant studies suggest designs that "look" different should elicit similar performance, where these stimulus parameters are identical. The current study sought to explore other, previously unidentified parameters.
