Advances in the medical treatment of HIV have made it clear that adherence to highly active antiretroviral treatment is a crucial feature for treatment success. The present paper had two goals: (1) to examine psychosocial predictors of adherence in persons receiving HIV antiretroviral therapy; (2) to compared two minimal-treatment interventions to increase HIV medication adherence in a subset of persons who self-reported less than perfect adherence. One of the interventions, Life-Steps, is a single-session intervention utilizing cognitive-behavioral, motivational interviewing, and problem-solving techniques. The other intervention, self-monitoring, utilizes a pill-diary and an adherence questionnaire alone. Significant correlates of adherence included depression, social support, adherence self-efficacy, and punishment beliefs about HIV. Depression was a significant unique predictor of adherence over and above the other variables. Both interventions yielded improvement in adherence from baseline, and the Life-Steps intervention showed faster improvements in adherence for persons with extant adherence problems. 相似文献

Anxiety sensitivity is the fear of anxiety-related sensations, and is measured by the 16-item Anxiety Sensitivity Index (ASI). Despite the popularity and utility of the ASI in research, a number of studies have provided evidence for the inadequacy of several items, and item-to-scale correlations for the ASI have not been published. In this study, a converging set of analyses to evaluate the item adequacy and factor structure of the ASI was used. The results of these multiple analyses converged nicely suggesting that Items 1, 5, 7, 8, and 13 should be considered for removal from the instrument. The impact of removing these problematic items from the scale was explored through the reanalysis of data from 3 previously published studies that compared the original ASI with the new 11-item version (the ASI minus the 5 problematic items). The results of these analyses suggest that the 2 scales function comparably in many respects but that the new version may be a more precise measure of anxiety sensitivity. The 11-item ASI appears to tap 2 primary aspects of anxiety sensitivity: fears of somatic sensations of anxiety and fears of loss of mental control. Suggestions for further development of the ASI are offered. 相似文献

The present article describes a software program in Visual Basic .NET designed to simulate three slot machines on a computer
screen. This software is described in detail regarding utility, downloading, and usage; and data are presented illustrating
the software’s potential for researchers interested in gambling behavior. A simulation of multiple slot machines such as this
enables researchers to evaluate players’ preferences across various machines. In the highlighted experiment, 18 recreational
slot machine players played the software for extra course credit and a chance at cash prizes. All participants played a version
of the simulation in which every 5th response on average was a win, whereas the remaining trials were a loss. However, on
those loss trials, a varying distribution of almost wins or near misses (i.e., two winning symbols on the payoff line and
the final winning symbol directly above or below the payoff line) were presented in percentages of 15, 30, or 45. While no
preferences across the three options could be predicted on the basis of reinforcement history alone, deviations from equal
choices across the games were noted and appeared to be the result of the presentations of near-miss losing trials. Implications
for a greater understanding of pathological gambling are presented. 相似文献

One factor that influences the success of emotion regulation is the manner in which the regulated emotion was generated. Recent research has suggested that reappraisal, a top-down emotion regulation strategy, is more effective in decreasing self-reported negative affect when emotions were generated from the top-down, versus the bottom-up. On the basis of a process overlap framework, we hypothesized that the neural regions active during reappraisal would overlap more with emotions that were generated from the top-down, rather than from the bottom-up. In addition, we hypothesized that increased neural overlap between reappraisal and the history effects of top-down emotion generation would be associated with increased reappraisal success. The results of several analyses suggested that reappraisal and emotions that were generated from the top-down share a core network of prefrontal, temporal, and cingulate regions. This overlap is specific; no such overlap was observed between reappraisal and emotions that were generated in a bottom-up fashion. This network consists of regions previously implicated in linguistic processing, cognitive control, and self-relevant appraisals, which are processes thought to be crucial to both reappraisal and top-down emotion generation. Furthermore, individuals with high reappraisal success demonstrated greater neural overlap between reappraisal and the history of top-down emotion generation than did those with low reappraisal success. The overlap of these key regions, reflecting overlapping processes, provides an initial insight into the mechanism by which generation history may facilitate emotion regulation. 相似文献
