The participants included undergraduate students from the same course offered in two different semesters. We investigated students' perceptions of interactions with the instructor and fellow students, their confidence in utilizing the Internet (Internet self-efficacy), and the satisfaction level that students perceived throughout the learning process with Interwise. We also examined the effect of interactions and Internet self-efficacy on student satisfaction. Data collected through paper-based and online surveys were analyzed using correlation and multiple regression. The results revealed that overall, learners perceived Interwise as a tool that was moderately easy to use for synchronous learning. Learners seemed to prefer using the Interwise features, such as emotion icons, talk, or raise hand, to interact with their instructor. Learners had high confidence in gathering data or getting support through the Internet, but low confidence in resolving Internet related problems. Both learner-learner and learner-instructor interactions were significant predictors of student satisfaction, while Internet self-efficacy did not significantly contribute to satisfaction. Learner-instructor interaction was found to be the strongest predictor of student satisfaction.

This was a preliminary study towards a dissertation work which involved the establishment of interaction and satisfaction scales through a content validity survey. Regression analysis was performed to determine the contribution of predictor variables to student satisfaction. The effects of student background variables on predictors were explored. The results showed that learner-instructor interaction, learner-content interaction, and Internet self-efficacy were good predictors of student satisfaction while interactions among students and self-regulated learning did not contribute to student satisfaction. Learner-content interaction explained the largest unique variance in student satisfaction. Additionally, gender, class level, and time spent online per week seemed to have influence on learner-learner interaction, Internet self-efficacy, and self-regulation.

The current study sought to examine the influence of psychiatric disorder, substance use disorder, and gender on risky sexual behavior in this vulnerable population. Participants were 228 female and 202 male outpatients (66% mood disorder, 34% schizophrenia) each of whom took part in a Structured Clinical Interview for the DSM-IV and a comprehensive assessment of sexual risk behavior. Univariate and multivariate analyses tested a priori hypotheses. The results indicated that risk behavior was more frequent among patients diagnosed with a mood disorder (compared to those diagnosed with schizophrenia) and/or with a substance use disorder (compared to those without a co-morbid disorder). We recommend routine HIV risk screening and risk reduction programs for this vulnerable population.

We compared Merrill's rubric with other recognized rubrics to explore the convergence of course awards with high scores on the Merrill's system, and convergence of scores on the Merrill system with relevant scores on the other evaluation tools. This was an exploratory study which attempted to see how high-quality courses employ Merrill's first principles of instruction. From our results we believe that Merrill's first principles should be included in the myriad of criteria for determining online course quality. Award-winning courses tend to use Merrill's first principles, and it seems likely that there is still significant room for improvement of even award-winning courses.

This study investigated how brief supportive educational modules delivered as part of an interactive voice response self-monitoring (IVR SM) system helped stabilize initial resolution among otherwise untreated problem drinkers. Recently resolved problem drinkers allocated to the intervention group of a randomized controlled trial were offered IVR access for 24 weeks to report daily drinking and hear weekly educational modules designed to support resolution. Using data from the 70 active IVR callers, hierarchical linear models evaluated whether module retrieval reduced subsequent alcohol consumption, including high-risk drinking, and whether module retrieval attenuated the effects on drinking of established proximal risk factors for relapse (e.g., urges, drug use, and weekends). The analyses controlled for...

Subjects were 52 men and 28 women participating in daily self-reports of alcohol consumption for a total of 2 years, collected via interactive voice response technology (IVR). In addition, retrospective self-reports of alcohol consumption on September 11, 2001, were collected by telephone interview 4-5 days following the terrorist attacks. Retrospective error was calculated as the difference between the IVR self-report of drinking behavior on September 11 and the retrospective self-report collected by telephone interview. Retrospective error was analyzed as a function of gender and baseline drinking behavior during the 365 days preceding September 11, 2001 (termed "the baseline"). The intraclass correlation (ICC) between daily IVR and retrospective self-reports of alcohol consumption on September 11 was...

Method: Participants in an ongoing longitudinal study submitted daily reports on alcohol consumption and mood via Interactive Voice Response technology. The daily self-reports of 86 subjects between September 11, 2000, and December 30, 2001, were used to analyze alcohol consumption and mood before, on and after September 11, 2001. Data were analyzed by statistical process control (SPC) analyses. Results: Descriptive analyses revealed that by comparison with the average alcohol consumption on the previous 52 Tuesdays, women drank 33.9% more alcohol and men 13.9% more on Tuesday, September 11, 2001. Compared with the average alcohol consumption on the 365 days preceding September 11, however, no increase in alcohol consumption was found. SPC analyses did not indicate a significant increase of alcohol consumption in response to September 11 in terms of baseline standard error computed from the 365 days preceding the events. Marked increases, on the other hand, were found in self-reported levels of stress, anger and sadness, with elevations up to nine standard errors beyond average baseline ratings. Negative emotions remained elevated for up to 69 days following the attacks. Conclusions: Vicarious experience of terrorism affects emotions significantly but may not significantly affect alcohol consumption among drinkers remote from the events. (J. Stud.

Based on Hobfoll's (1988, 1989) conservation of resources (COR) theory, we predicted that acute resource loss would be more distressing than chronic economic lack. That is, although chronically impoverished conditions are stressful, the attendant resource losses created will be more distressing. We further predicted that mastery and social support would be more beneficial in offsetting the negative consequences of acute resource loss than the negative consequences of chronic economic lack, because acute loss creates identifiable demands that resources may address. Hence, we hypothesized that mastery and social support would show stress buffering effects only for material loss, not chronic lack. The findings generally supported the hypotheses, but mastery buffered only European American women's resource ...

In this review, we discuss advantages and recent applications of interactive voice response technology (IVR) to HIV risk behavior research, including feasibility studies, assessment mode comparisons between IVR and alternative self-reporting methods, and unique findings derived from event-level data analyses illuminating risk factors for unprotected intercourse on within-person level. We also review reactivity effects of daily IVR self-reports and applications of IVR systems in risk behavior intervention research. We conclude that IVR is a feasible and highly promising tool for various research and health care applications that should be considered more frequently for use in HIV-risk populations.
