Knowledge of how specific factors affect transition outcomes can be used to tailor transition interventions and resources to the needs of students with TBI. Findings related to special education and medical rehabilitation services should be interpreted with caution as the criteria for receipt of both types of services and the links between such services and functional outcomes are unclear.
The primary objective of this study was to better understand the technology needs, barriers and strategies of individuals with acquired cognitive impairments (ACI) in order to design and modify technologies with potential for alleviating the diminished independence and social isolation common in this population. The authors hypothesized that (1) higher rates of computer use would be reported by younger, more highly educated individuals with ACI, those with less severe injuries and those with previous computer experience; (2) A low percentage of survey respondents would own their own computers; and (3) People with ACI would experience social isolation and report low frequency of connecting with important people who live far away. A total of 133 individuals with ACI, professionals and care providers completed the survey. To gain more specific information, seven focus groups were conducted with 66 individuals with ACI and 20 care providers. Finally, 10 current email users participated in structured conversations, detailing their strategies for using email. The survey revealed that 80% of subjects with ACI reported owning a computer. Age and education were not predictors of computer use, but individuals whose ACI was the result of more severe injuries were less likely to use computers. As expected, respondents reported that maintaining contact with distant loved ones is problematic. The focus groups and conversations provided more detail about the communication needs of the population and the relative advantages and disadvantages of email compared with telephone and mail. Participants also identified barriers to email use they had encountered or feared they would encounter when using email. A number of accommodations to overcome these barriers were suggested. The results of the survey, focus groups and conversations confirmed the utility of email and other technologies for people with ACI and the need to make these technologies more accessible. The results and suggestions provided by the focus groups and interviews are being used in the design of Think and Link, an email interface for use by individuals with ACI.
The experimental evaluation of two components of a community intervention to prevent adolescent tobacco use are described. Youth antitobacco activities (e.g., peer quizzes, sidewalk art, poster and T-shirt giveaways, etc.) and family communications activities (pamphlets to parents and student quizzes of parents) were evaluated in two time-series experiments, each of which was conducted in two experimental and one control community. Students in Grades 6 and 8 and their parents were assessed in a series of four phone surveys in the first experiment and six phone surveys in the second. Implementation of the youth antitobacco and family communications activities led to significantly greater exposure of young people to antitobacco information. They led to increases in parent and youth knowledge about tobacco use and more negative attitudes toward tobacco. In Experiment 2, youths in intervention communities had significantly lower rated intentions to smoke. The findings suggest the value of a modular approach to community interventions for influencing the social context relevant to the onset of adolescent tobacco use.
Experimental evaluations of substance use prevention programs are hampered by high rates of subject attrition. Attrition threatens the internal validity of these studies when attrition is greater in one condition than another. Statistical tests of the effects of attrition are typically lacking. Attrition threatens the external validity of studies because one may not be able to generalize effects of programs to dropouts who are systematically different from those who remain. SUMMARY AND CONCLUSIONSThis paper examines the problem of attrition in prevention research. Attrition involves the loss of subjects in post-treatment and follow-up assessments. In substance use prevention studies up to 1991, 66% of the smoking prevention studies reported attrition rates, but only 14.7% of studies of alcohol and drug use prevention reported attrition. The mean rate of reported attrition was about 25%.Attrition threatens the internal validity. Different numbers of subjects or subjects with different characteristics may drop out of different conditions and any differences that are found among conditions could be due to differential loss of subjects rather than to the effects of those conditions. It is thus important to test whether there are significant differences among conditions in the rate of dropout and in the characteristics of those who have dropped out of each condition. Unfortunately, only a minority of prevention studies have tested for differences in attrition. Where tests have been conducted, some studies have found that there were significant differences among conditions in the rate or characteristics of dropouts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
