The effect of education type on common misconceptions of traumatic brain injury.

Purpose: In the current study, we investigated the effects of existing education materials-either a Traumatic Brain Injury (TBI) factsheet or personal stories of people with TBI-on undergraduate students' misconceptions and attributions about the causes of TBI-related behavior.

Method: Undergraduate students (N = 164) were recruited through the university participant pool. The participants were randomly assigned to receive either a factsheet about TBI, personal stories of people with TBI, or a control reading.

Perceptions of vulnerability to HIV/AIDS: a comparison of two college cohorts, 1990 and 2005.

Theories of preventive health behavior posit that perceived vulnerability to health threats motivates self-protective behavior. Fifteen years after an initial study of college students' perceptions of their vulnerability to HIV, a replication was conducted on the same campus in 2005. Comparisons between cohorts on vulnerability judgements were conducted to examine whether, and to what extent, student perceptions had changed across time.
