Purpose: In men with localized prostate cancer, the addition of androgen-deprivation therapy (ADT) or a brachytherapy boost (BT) to external beam radiotherapy (EBRT) have been shown to improve various oncologic end points. Practice patterns indicate that those who receive BT are significantly less likely to receive ADT, and thus we sought to perform a network meta-analysis to compare the predicted outcomes of a randomized trial of EBRT plus ADT versus EBRT plus BT.

Materials And Methods: A systematic review identified published randomized trials comparing EBRT with or without ADT, or EBRT (with or without ADT) with or without BT, that reported on overall survival (OS).

Expert testimony concerning risk and its communication to the trier of fact has important implications for some of the most significant legal decisions. In a simulated sexual violent predator hearing, we examined how mock jurors interpret and use recidivism risk expert testimony communicated either categorically, using verbal labels, or probabilistically, using numeric values. Based upon the STATIC-99R, we compared mock jurors' decision-making and verdicts when we manipulated the style of risk communication across four different risk levels.

The role of experts and their presentation of testimony in insanity cases remain controversial. In order to decrease possible expert bias associated with this testimony, a number of different alternatives to adversarial presentation have been suggested. Two such alternatives are the use of court-appointed experts and the use of concurrent testimony (or "hot-tubbing"), in which opposing experts provide testimony concurrently and converse with each other directly.

Public fear has driven legislation designed to identify and exclude sexual offenders from society, culminating in sexually violent predator (SVP) statutes, in which a sex offender who has served his prison sentence is hospitalized indefinitely if a jury determines that he is likely to reoffend as a result of a mental disorder. Jurors rarely vote not to commit a previously-convicted sex offender as an SVP. This study tests whether the mere label of "sexually violent predator" affects these legal decisions.

An intervention designed to correct affective and cognitive biases was tested in the context of a civil commitment hearing of a sexually violent predator. Potential differences between a college student mock jury sample and a more representative, juror venire sample in reaction to these bias correction interventions were explored. In the first of two experiments, undergraduate mock jurors (n = 130) demonstrated a leniency effect when the sex offender's attorney acknowledged jurors' emotional reactions and motivated them to thoughtfully weigh the evidence.

This paper reviews the four types of validity that make up Cook and Campbell's traditional approach for social science research in general and psychological research in particular: internal validity, statistical conclusion validity, external validity, and construct validity. The most important generalizability threat to the validity of jury research is not likely a selection main effect (i.e.

Despite concerns about generalizability, past mock trial research has concluded that effects of sample (i.e., students versus representative mock jurors) are negligible.

Significant controversy surrounds how psychologists should balance competing interests when considering whether and under what conditions third parties should be permitted to be present during psychological evaluations. This is especially true in forensic contexts where much is often at stake for those being assessed. Unfortunately, existing professional statements on this issue provide limited guidance to practitioners on how to think about this issue.

Past research examining the effects of expert testimony on the future dangerousness of a defendant in death penalty sentencing found that jurors are more influenced by less scientific clinical expert testimony and tend to devalue scientific actuarial testimony. This study was designed to determine whether these findings extend to civil commitment trials for sexual offenders and to test a theoretical rationale for this effect. In addition, we investigated the influence of a recently developed innovation in risk assessment procedures, Guided Professional Judgment (GPJ) instruments.

A limited amount of research exists examining the ability of the Criminal History Score of the Federal Sentencing Guidelines (Guidelines) to achieve one of its most essential objectives: prediction of recidivism. Building on the work of Schopp [Schopp, R. (2001).

Using a simulated civil case, this experiment investigated whether mock jurors: (a) are able to disregard hearsay evidence when admonished to do so, (b) experience psychological reactance and "backfire effects" in proportion to the strength of judicial admonition instructing them to disregard hearsay evidence, and (c) are able to recognize and disregard hearsay evidence without judicial instructions. Results indicate that jurors were unable to disregard inadmissible hearsay testimony in some legal decisions regardless of whether there were judicial instructions to do so. Jurors exhibited backfire effects paying more attention to inadmissible hearsay evidence when they were strongly instructed to disregard it.

Past research examining the effects of actuarial and clinical expert testimony on defendants' dangerousness in Texas death penalty sentencing has found that jurors are more influenced by less scientific pure clinical expert testimony and less influenced by more scientific actuarial expert testimony (Krauss & Lee, 2003; Krauss & Sales, 2001). By applying cognitive-experiential self-theory (CEST) to juror decision-making, the present study was undertaken in an attempt to offer a theoretical rationale for these findings. Based on past CEST research, 163 mock jurors were either directed into a rational mode or experiential mode of processing.

A limited amount of research exists examining the ability of clinical or intuitive adjustments of formalistic methods of decision-making to improve upon predictive accuracy beyond that of the original measure. Using receiver operator characteristic (ROC) curves and the departure decisions of federal judges, the recidivism predictive utilities of two measures were compared. The two measures were the Criminal History category, based on the Federal Sentencing Guidelines (a formalistic procedure), and a re-coded measure of criminal history derived from the sentences actually imposed by judges after they departed from the Guidelines upwards or downwards for recidivism reasons (an adjustment to the formalistic procedure).
