We also tested gender differences for both victimization and social risk. Participants consisted of 3,052 emerging adults (M(age) = 20.0 years; SD = 2.21) entering(More)

The sample included 110 emerging adults entering outpatient substance use treatment who were heavy cannabis(More)
The current optical technology is costly, bulky, fragile in their alignment, and difficult to integrate with electronic systems, both in terms of the fabrication process and in terms of delivery and retrieval of massive volumes of data that the optical elements can process. Our most recent work emphasizes the construction of optical subsystems directly(More)
Obtaining accurate assessment data from adolescents in treatment aids clinical decision making and facilitates more accurate outcome evaluations. However, findings could be biased due to underreported substance use and mental health symptoms. This article compares self-reports of youth in non-White matched client-assessor dyads and those in nonmatched(More)

Although victimization and SM may appear to be separate problems, research suggests an(More)
Very little research exists on how self-perceived emerging adult status is associated with substance use among low-income emerging adults. The Inventory of Dimensions of Emerging Adulthood (IDEA) was administered to emerging adults (EAs) ages 18-25 screened for substance use problems (n = l05) in a state-subsidized, not-for-profit treatment agency.
