Usability is increasingly recognized as an important quality factor for interactive software systems, including traditional GUIs-style applications, Web sites, and the large variety of mobile and PDA interactive services. Unusable user interfaces are probably the single largest reasons why encompassing interactive systems – computers plus people, fail in(More)
OBJECTIVE Research about the role of alcohol-related expectancies in the drinking behavior of young people has two crucial limitations: a paucity of longitudinal studies and questions about the construct validities of extant expectancy questionnaires. This study concerned the Alcohol Expectancy Questionnaire for Adolescents (AEQ-A) and its relation to(More)

Psychiatric diagnoses and objective parent checklists are alternative ways to describe child adjustment problems. There has recently been interest in evaluating the degree of agreement or convergence between these sources of information. This paper addresses three issues neglected by researchers in this area. The appropriateness of the use of indices of(More)
While researchers usually are concerned about psychometric properties of psychological tests estimated using large samples, most clinical decision-makers must evaluate the accuracy of test results for individuals. This is particularly true as regards tests that have cutting scores to determine, for example, whether to assign a particular diagnosis or accept(More)
Evidence shows that integrated development environments (IDEs) are too often functionality-oriented, complex and difficult to use, learn, and master. This article describes challenges in the design of usable IDEs and in the evaluation of the usability of such tools. It presents the results of three different empirical studies of IDE usability. Different(More)
Latent variable path analysis (LVPA) is undoubtedly one of "the" new statistical techniques being used increasingly often by clinical researchers. Although well suited for some types of clinical research, LVPA can be a somewhat intimidating technique for novices. This work is intended to provide a non-mathematical introduction to the advantages and problems(More)
Alcohol use and abuse among adolescents is a serious and complex social problem. Previous research in this area has usually consisted of correlationaJ studies that identified individual factors predictive of teenage drinking. Such simple analytic methods, however, did not allow investigation of interrelations among those parameters that may affect(More)
Of various means to prevent alcohol-related problems among adolescents, school-based educational approaches are very prevalent. The potential effectiveness of such programs will be limited, however, if teenage drinking is determined by factors beyond the influence of school-based interventions, such as demographic characteristics or quality of family(More)
The present study examined the differential predictive accuracy of seven Minnesota Multiphasic Personality Inventory alcoholism scales and two drug abuse scales across both sex and race in a sample of 171 alcoholic inpatients. Results demonstrated considerable variance among these scales in their ability to predict alcohol and other drug use, expectancies,(More)
