Perceptions of blind proficiency testing among latent print examiners.

In recent years, scholars have levied multiple criticisms against traditional proficiency testing procedures in forensic laboratories. Consequently, on several occasions, authorities have formally recommended that laboratories implement blind proficiency testing procedures. Implementation has been slow, but laboratory management has increasingly expressed interest in initiating blind testing in at least some forensic disciplines, with some laboratories conducting blind testing in almost all disciplines.

What types of information can and do latent print examiners review? A survey of practicing examiners.

Understanding typical work practices is important to understanding the decision-making process underlying latent print comparison and improving the reliability of the discipline. Despite efforts to standardize work practices, a growing literature has demonstrated that contextual effects can influence every aspect of the analytic process. However, very little is known about what types of information are available to latent print examiners, and what types of information latent print examiners routinely review.

Does image editing improve the quality of latent prints? An analysis of image-editing techniques in one crime laboratory.

Field research within latent print comparison has remained sparse in the context of an otherwise growing body of literature examining the discipline. Studies examining how ACE-V procedures are implemented within active crime laboratories are especially lacking in light of research suggesting significant variability in examiner practices despite standardized ACE-V procedures. To date, no studies have examined a potentially important aspect of the Analysis phase: digital image editing.

Gun violence among young adults with a juvenile crime record in North Carolina: Implications for firearm restrictions based on age and risk.

Youth who acquire a juvenile crime record may be at increased risk of perpetrating gun violence as adults. North Carolina and 22 other states permit young adults who were adjudicated by a juvenile court - even for some felony-equivalent offenses - to legally access firearms. Effectiveness of gun restrictions for adults with juvenile crime histories has not been systematically studied.

Latent print quality in blind proficiency testing: Using quality metrics to examine laboratory performance.

Calls for blind proficiency testing in forensic science disciplines intensified following the 2009 National Academy of Sciences report and were echoed in the 2016 report by the President's Council of Advisors on Science and Technology. Both practitioners and scholars have noted that "open" proficiency tests, in which analysts know they are being tested, allow for test-taking behavior that is not representative of behavior in routine casework. This study reports the outcomes of one laboratory's blind quality control (BQC) program.

Judges and forensic science education: A national survey.

In criminal cases, forensic science reports and expert testimony play an increasingly important role in adjudication. More states now follow a federal reliability standard, which calls upon judges to assess the reliability and validity of scientific evidence. Little is known about how judges view their own background in forensic scientific evidence, and what types of specialized training they receive on it.

Latent print comparison and examiner conclusions: A field analysis of case processing in one crime laboratory.

Scholarship on the latent print comparison process has expanded in recent years, responsive to the call for rigorous research by scholarly groups (e.g., National Academy of Sciences, 2009; President's Council of Advisors on Science and Technology, 2016).

The impact of misdemeanor arrests on forensic mental health services: A state-wide review of Virginia sanity evaluations.

Objective: We examined the prevalence of criminal defendants facing only misdemeanor charges and referred for forensic mental health evaluations of legal sanity (criminal responsibility) in a state-wide sample of sanity reports. We sought to describe this population of defendants, particularly as compared to defendants facing felony charges and referred for evaluation of legal sanity.

Hypotheses: We hypothesized that, among those referred for sanity evaluations, defendants facing only misdemeanor charges would have higher rates of serious mental illness than would defendants charged with felonies, as evidenced by their mental status during the evaluation and at the time of alleged offenses.

How do latent print examiners perceive proficiency testing? An analysis of examiner perceptions, performance, and print quality.

Proficiency testing has the potential to serve several important purposes for crime laboratories and forensic science disciplines. Scholars and other stakeholders, however, have criticized standard proficiency testing procedures since their implementation in laboratories across the United States. Specifically, many experts label current proficiency tests as non-representative of actual casework, at least in part because they are not sufficiently challenging (e.

Competency to stand trial evaluations: A state-wide review of court-ordered reports.

Competence to stand trial (CST) evaluations are a critical part of certain criminal proceedings, and competence-related evaluation and treatment are an increasing part of public mental health services. Whereas more research describes the defendants undergoing competence evaluations, less research has examined the actual reports detailing those competence evaluations. This study reviewed 3,644 court-ordered CST evaluation reports submitted by 126 evaluators in Virginia since Virginia initiated an oversight system allowing for comprehensive review.

Latent Print Proficiency Testing: An Examination of Test Respondents, Test-Taking Procedures, and Test Characteristics.

Proficiency testing is a key component of quality assurance programs within crime laboratories and can help improve laboratory practices. However, current proficiency testing procedures contain significant limitations and can be misinterpreted by examiners and court personnel (Garrett & Mitchell, 2018). To evaluate some of these limitations, we surveyed latent print examiners (n = 198) after they completed a Collaborative Testing Services, Inc.

What do forensic analysts consider relevant to their decision making?

In response to research demonstrating that irrelevant contextual information can bias forensic science analyses, authorities have increasingly urged laboratories to limit analysts' access to irrelevant and potentially biasing information (Dror and Cole (2010) [3]; National Academy of Sciences (2009) [18]; President's Council of Advisors on Science and Technology (2016) [22]; UK Forensic Science Regulator (2015) [26]). However, a great challenge in implementing this reform is determining which information is task-relevant and which is task-irrelevant. In the current study, we surveyed 183 forensic analysts to examine what they consider relevant versus irrelevant in their forensic analyses.

Perceptions and estimates of error rates in forensic science: A survey of forensic analysts.

Every scientific technique features some error, and legal standards for the admissibility of scientific evidence (e.g., Daubert v.

Do evidence submission forms expose latent print examiners to task-irrelevant information?

Emerging research documents the ways in which task-irrelevant contextual information may influence the opinions and decisions that forensic analysts reach regarding evidence (e.g., Dror and Cole, 2010; National Academy of Sciences, 2009; President's Council of Advisors on Science and Technology, 2016).

Neuropsychological correlates of self-reported impulsivity and informant-reported maladaptive behaviour among veterans with posttraumatic stress disorder and traumatic brain injury history.

Objective: Frontal lobe deficits resulting from traumatic brain injury (TBI) and/or posttraumatic stress disorder (PTSD) have been linked to impulsive behaviour. We sought to examine whether neuropsychological performance predicted self-reported impulsivity and informant-reported maladaptive behaviour.

Method: We administered the Delis-Kaplan Executive Function System (D-KEFS) to 116 Iraq/Afghanistan-era veterans diagnosed with a history of TBI and PTSD.

Insanity findings and evaluation practices: A state-wide review of court-ordered reports.

Evaluations of legal sanity are some of the most complex and consequential mental health evaluations that forensic clinicians perform for the courts. Thus, there is strong reason to monitor the wide-scale process and conclusions of sanity evaluations. In this study, we review 1,111 court-ordered sanity evaluation reports submitted by 74 evaluators in Virginia from the first year after the state initiated an oversight system that allowed for such comprehensive review.

Does the Convergent Validity of the PAI Antisocial Features Scale Depend on Offender Response Style?

Researchers have recently questioned the utility of the response style indicators included on many self-report measures of personality and psychopathology. We examined whether the size of convergent validity coefficients for Personality Assessment Inventory (PAI) Antisocial Features (ANT) scores depends on PAI validity scale scores. Using PAI and Psychopathy Checklist-Revised (PCL-R) scores from 477 offenders evaluated for civil commitment as sexually violent predators, we found that PAI Positive Impression (PIM), Negative Impression (NIM), Malingering Index (MAL), Defensiveness Index (DEF), and Infrequency (INF) scores moderated the association between ANT and PCL-R scores.

A Validation Study of the Need for Affect Questionnaire-Short Form in Legal Contexts.

We evaluated the psychometric properties of scores on the Need for Affect-Short Form (NAQ-S) in 3 samples: undergraduate students (Sample I), jury-eligible community members (Sample II), and forensic clinicians (Sample III). Concerning factor structure, the NAQ-S 2-factor structure displayed good fit to the data in Sample I, with mostly acceptable levels of internal consistency for both approach and avoidance scores. Construct validity patterns were observed such that approach scores were most strongly correlated with female gender and trait agreeableness scores, whereas avoidance scores were most strongly correlated to trait agreeableness scores.

Personality Assessment Inventory scores as predictors of misconduct, recidivism, and violence: A meta-analytic review.

More than 30 studies have examined the ability of scores on the Personality Assessment Inventory (PAI; Morey, 1991, 2007) to predict violence or misconduct. The Antisocial Features (ANT), Aggression (AGG), and Violence Potential Index (VPI) Scales of the PAI, in particular, have received substantial attention as predictors of institutional infractions and criminal recidivism. The current study used meta-analysis to provide a comprehensive review of the ability of scores on these and other PAI scales to predict misbehavior.

Evaluator differences in Psychopathy Checklist-Revised factor and facet scores.

Recent research suggests that the reliability of some measures used in forensic assessments--such as Hare's (2003) Psychopathy Checklist-Revised (PCL-R)--tends to be weaker when applied in the field, as compared with formal research studies. Specifically, some of the score variability in the field is attributable to evaluators themselves, rather than the offenders they evaluate. We studied evaluator differences in PCL-R scoring among 558 offenders (14 evaluators) and found evidence of large evaluator differences in scoring for each PCL-R factor and facet, even after controlling for offenders' self-reported antisocial traits.
