Opinion Climates in Social Media: Blending Mass and Interpersonal Communication

Social media's capacity for users to generate, comment on, and forward content (including mass media messages) to other users has created new forms of mass interpersonal communication. These systems render observable processes underlying the formation of opinion climates. Five attributes of contemporary electronic opinion environments can alter the way users gauge, form, and express opinions on topics of public interest: the juxtaposition of mass media and user‐generated content, ideological homogeneity and heterogeneity of online networks, technical ease with which to express opinions, the reach of messages, and networked audiences. These attributes facilitate analysis of theoretical and empirical works from different scholarly traditions, suggesting lines of inquiry that can enrich the analysis of (public) opinion formation via current communication technologies.     

Mild Traumatic Brain Injury and Posttraumatic Stress Disorder in Returning Iraq and Afghanistan War Veterans: Implications for Assessment and Diagnosis

Mild traumatic brain injury (MTBI) and posttraumatic stress disorder (PTSD) are considered the “signature injuries” of combat soldiers returning from Iraq and Afghanistan. Both disorders can greatly affect the functioning of soldiers, yet the disorders often go undetected or are misdiagnosed by both military and civilian health care providers. This article provides information about MTBI and PTSD in returning combat soldiers along with implications for assessment and diagnosis.     

The Role of Sleep Disturbance in Suicidal and Nonsuicidal Self‐Injurious Behavior among Adolescents

The relationship between different sleep disturbances and self‐harm thoughts and behaviors was examined among 223 adolescents presenting to a community clinic for mood disorders and suicidal and nonsuicidal self‐injurious behaviors. Two‐thirds of the adolescents reported nightly, severe sleep complaints. Relative to adolescents without significant sleep complaints, patients with severe sleep complaints at the time of clinic entry endorsed significantly more engagement in nonsuicidal self‐injury. Middle insomnia and circadian reversal were both significant predictors of suicide attempts. Terminal insomnia was significantly associated with suicidal ideation. Results support the importance of assessing sleep difficulties among adolescents at risk for suicide.
