Marijuana Effect Expectancies: Relations to Social Anxiety and Marijuana Use Problems
Abstract High social anxiety is related to marijuana problems, yet the nature of this relation remains unclear. We examined relations between marijuana effect expectancies, social anxiety, and marijuana among undergraduates ( N = 337). Social anxiety was related positively to Negative Expectancies and negatively to Tension Reduction Expectancies. Among socially anxious individuals, greater belief that marijuana produces Cognitive and Behavioral Impairment was associated with greater marijuana use rates. Negative Expectancies mediated the social anxiety–marijuana problems link. These data provide new insight into problematic marijuana use among this high-risk group.
The objective of the present study is to find out how the use of the Internet is perceived and felt by the students. The sample was made up of 51 students from 4 educational establishments in the VIII, IX and X Regions in Chile. The Coopersmith Self-Esteem Inventory was used in the collection of quantitative data. Qualitative data was gathered using focus groups and in-depth interviews. The quantitative results indicate that there are differences between the evaluated groups with respect to self-esteem. The principal results of the qualitative analysis, are related to the students' experience of the use of computers, the use of the internet and the experience of communication, observing in general a positive perception associated with learning and the use of technology.
