ABSTRACT Despite growing evidence of the efficacy of electronic screening and brief interventions for reducing unhealthy alcohol use, there is no published work describing the development of such interventions. We describe the process of developing and implementing an electronic screening and brief intervention in a large university population.
Thematic analysis of seven focus groups, involving a total of 69 students, informed the content and design of THRIVE (Tertiary Health Research Intervention Via Email). Pilot testing was conducted through usability analysis with a further 16 students. A random sample of 13,000 undergraduates was invited to complete screening and hazardous drinkers were randomised to receive Web-based assessment and feedback or screening alone. Participants' use of THRIVE was examined through server log analysis and responses to questions on instrument design/usability during follow-up assessment 6 months later.
A total of 7237 students (56% of those invited) completed screening; 2435 (34%) screened positive for unhealthy drinking; 1251 were randomly assigned to receive the intervention; and 1184 served as controls. In total, 99% of participants found THRIVE easy to complete, 76% said it provided personally relevant information and 55% said they would recommend it to a friend with a drinking problem. Thirty per cent sought additional information on support services through the site.
Key design elements include ease of access (e.g. via an emailed hyperlink), length (<10 min), clear, non-judgmental language, personalised normative feedback and links to appropriate services. The study demonstrates the potential reach of a carefully implemented intervention in a high-risk, non-treatment-seeking population group.

    ABSTRACT: The study purpose was to determine the predictors of watching most of a Web-based streaming video and whether data characteristics differed for those watching most or only part of the video. A convenience sample of 650 students (349 Asian Americans and 301 non-Hispanic whites) was recruited from a public university in the United States. Study participants were asked to view a 27-minute suicide awareness streaming video and to complete online questionnaires. Early data monitoring showed many, but not all, watched most of the video. We added software controls to facilitate video completion and defined times for a video completion group (≥26 minutes) and video noncompletion (<26 minutes) group. Compared with the video noncompletion group, the video completion group included more females, undergraduates, and Asian Americans, and had higher individualistic orientation and more correct manipulation check answers. The video noncompletion group skipped items in a purposeful manner, showed less interest in the video, and spent less time completing questionnaires. The findings suggest that implementing software controls, evaluating missing data patterns, documenting the amount of time spent completing questionnaires, and effective manipulation check questions are essential to control potential bias in Web-based research involving college students.

    ABSTRACT: The university environment reinforces positive alcohol-related expectations and motivations for drinking among undergraduate students. High levels of hazardous consumption in this population lead to significant negative alcohol-related consequences, for individuals and those around them. This study sought to explore the contexts in which those who engage in hazardous drinking consume alcohol, their perceptions of safety and harm, and receptivity to health messages. Undergraduate university students (n = 69; aged 17 - 24 of both genders [57% female]) were purposively recruited into one of seven focus groups after screening with the Alcohol Use Disorders Identification Test (AUDIT) to select for hazardous drinking (score, >8) or moderate drinking. A focus group interview schedule was developed, which was informed by theory and tested for validity by a panel of experts. Qualitative analysis of the data revealed four thematic clusters: positive expectations; inescapable culture; defining situations; and permissible drunkenness. Drinking was associated with various personal and social advantages that reinforced participants’ intentions and/or willingness to drink. Alcohol played a meaningful role in the way in which participants identified with youth and university culture. Economical drinking was prominent, with students constantly negotiating pathways to intoxication within the confines of their budgets. Heavy drinking was viewed as permissible when in the home environment and/or in the company of trusted friends. Most students were unreceptive to health messages, and advice on restricting alcohol consumption seemed to have limited impact on drinking behaviour. Our findings clarify why some university students maintain or increase drinking behaviour despite known negative out-comes and offer useful insights to inform further research and the development of alcohol interventions specifically targeted at students.

    ABSTRACT: Issue addressed Australian university students consume large amounts of alcohol. There is little published information about personal and academic problems associated with this behaviour. We sought to estimate the prevalence, and identify variables associated with, alcohol-related problems among undergraduate hazardous drinkers. Methods The control group members (942 undergraduates, 53.3% male, mean age 19.4 years) of an internet-based intervention trial, who scored ≥8 on the Alcohol Use Disorders Identification Test, completed two validated questionnaires about their experience of alcohol-related problems in the preceding 4 weeks. Regression models were used to identify associations between individual characteristics and alcohol-related problems. Results One-quarter of participants had missed a class (25.6%) and/or had been unable to concentrate in class (25.7%), and 45% reported that their drinking had impacted negatively on their learning or grades. The most frequent non-academic problems were hangovers (74.8%), blackouts (44.8%), emotional outbursts (30.5%), vomiting (28.1%), arguments (20.2%) and drink-driving (23.2%). Male gender, lower age, being a smoker, being in the Faculty of Health (versus Humanities) and living in shared housing (versus with parents/guardians) were each associated with alcohol-related problems, whereas year of study had no association. Conclusions There is a high prevalence of preventable alcohol-related problems among undergraduates drinking at hazardous levels and a need for restriction of the availability and promotion of alcohol as well as intervention for individuals at high risk. So what? Universities have a duty of care to large populations of young people drinking at hazardous levels and should make greater efforts to address hazardous alcohol consumption.
