To adjust the decision criterion for the Word Memory Test (WMT, Green, 2003) to minimize the frequency of false positives.
Archival data were combined into a database (n = 3,210) to examine the best ...cut score for the WMT. We compared results based on the original scoring rules and those based on adjusted scoring rules using a criterion based on 16 performance validity tests (PVTs) exclusive of the WMT. Cutoffs based on peer-reviewed publications and test manuals were used. The resulting PVT composite was considered the best estimate of validity status. We focused on a specificity of .90 with a false-positive rate of less than .10 across multiple samples.
Each examinee was administered the WMT, as well as on average 5.5 (SD = 2.5) other PVTs. Based on the original scoring rules of the WMT, 31.8% of examinees failed. Using a single failure on the criterion PVT (C-PVT), the base rate of failure was 45.9%. When requiring two or more failures on the C-PVT, the failure rate dropped to 22.8%. Applying a contingency analysis (i.e., X
2
) to the two failures model on the C-PVT measure and using the original rules for the WMT resulted in only 65.3% agreement. However, using our adjusted rules for the WMT, which consisted of relying on only the IR and DR WMT subtest scores with a cutoff of 77.5%, agreement between the adjusted and the C-PVT criterion equaled 80.8%, for an improvement of 12.1% identified. The adjustmeny resulted in a 49.2% reduction in false positives while preserving a sensitivity of 53.6%. The specificity for the new rules was 88.8%, for a false positive rate of 11.2%.
Results supported lowering of the cut score for correct responding from 82.5% to 77.5% correct. We also recommend discontinuing the use of the Consistency subtest score in the determination of WMT failure.
The present study provides a meta-analysis of cognitive rehabilitation literature (
K
= 115,
N
= 2,014) that was originally reviewed by K. D. Cicerone et al. (2000, 2005) for the purpose of providing ...evidence-based practice guidelines for persons with acquired brain injury. The analysis yielded a small treatment effect size (
ES
= .30,
d
+
statistic) directly attributable to cognitive rehabilitation. A larger treatment effect (
ES
= .71) was found for single-group pretest to posttest outcomes; however, modest improvement was observed for nontreatment control groups as well (
ES
= .41). Correction for this effect, which was not attributable to cognitive treatments, resulted in the small, but significant, overall estimate. Treatment effects were moderated by cognitive domain treated, time postinjury, type of brain injury, and age. The meta-analysis revealed sufficient evidence for the effectiveness of attention training after traumatic brain injury and of language and visuospatial training for aphasia and neglect syndromes after stroke. Results provide important quantitative documentation of effective treatments, complementing recent systematic reviews. Findings also highlight gaps in the scientific evidence supporting cognitive rehabilitation, thereby indicating future research directions.
Objective: Citation and download data pertaining to the 2009 AACN consensus statement on validity assessment indicated that the topic maintained high interest in subsequent years, during which key ...terminology evolved and relevant empirical research proliferated. With a general goal of providing current guidance to the clinical neuropsychology community regarding this important topic, the specific update goals were to: identify current key definitions of terms relevant to validity assessment; learn what experts believe should be reaffirmed from the original consensus paper, as well as new consensus points; and incorporate the latest recommendations regarding the use of validity testing, as well as current application of the term 'malingering.' Methods: In the spring of 2019, four of the original 2009 work group chairs and additional experts for each work group were impaneled. A total of 20 individuals shared ideas and writing drafts until reaching consensus on January 21, 2021. Results: Consensus was reached regarding affirmation of prior salient points that continue to garner clinical and scientific support, as well as creation of new points. The resulting consensus statement addresses definitions and differential diagnosis, performance and symptom validity assessment, and research design and statistical issues. Conclusions/Importance: In order to provide bases for diagnoses and interpretations, the current consensus is that all clinical and forensic evaluations must proactively address the degree to which results of neuropsychological and psychological testing are valid. There is a strong and continually-growing evidence-based literature on which practitioners can confidently base their judgments regarding the selection and interpretation of validity measures.
Objective: Discrimination of patients passing vs. failing the Word Memory Test (WMT) by performance on 11 performance and symptom validity tests (PVTs, SVTs) from the Meyers Neuropsychological ...Battery (MNB) at per-test false positive cutoffs ranging from 0 to 15%. PVT and SVT intercorrelation in subgroups passing and failing the WMT, as well as the degree of skew of the individual PVTs and SVT in the pass/fail subgroups, were also analyzed.
Method: In 255 clinical and forensic cases, 100 failed and 155 passed the WMT, at a base-rate of invalid performance of 39.2%. Performance was contrasted on 10 PVTs and 1 SVT from the MNB, using per-test false positive rates of 0.0%, 3.3%, 5.0%, 10.0%, and 15.0% in discriminating WMT pass and WMT fail groups. These two WMT groups were also contrasted using the 10 PVTs and 1 SVT as continuous variables in a logistic regression.
Results: The per-PVT false positive rate of 10% yielded the highest WMT pass/fail classification, and more closely approximated the classification obtained by logistic regression than other cut scores. PVT and SVT correlations were higher in cases failing the WMT, and data were more highly skewed in those passing the WMT.
Conclusions: The optimal per-PVT and SVT cutoff is at a false positive rate of 10%, with failure of ≥3 PVTs/SVTs out of 11 yielding sensitivity of 61.0% and specificity of 90.3%. PVTs with the best classification had the greatest degree of skew in the WMT pass subgroup.
One hotly debated topic within the field of intimate partner violence (IPV) is the degree to which IPV can be understood as primarily a unidirectional versus bidirectional phenomena; this topic forms ...a key component of the gender symmetry versus asymmetry of domestic violence debate. Resolution of this controversy has important prevention and intervention implications. In the current study, a comprehensive review of the literature was conducted, and 48 studies that reported rates of bidirectional versus unidirectional physical violence (male-to-female and female-to-male) were uncovered using a variety of search engines and key terms; one relevant meta-analysis and one seminal book chapter were also identified. Included empirical studies were published in 1990 or later, appeared in peer-reviewed journals, and contained empirical data directly related to bidirectionality of violence. Studies that only reported correlations between self-reported perpetration and victimization were excluded from these analyses. Qualifying studies were then categorized by the nature of the sample they assessed (i.e., large population samples; smaller community; purposive or convenience samples; clinical or treatment-seeking samples; legal/criminal justice-related samples; and samples assessing the relationships of gay, lesbian, and/or bisexual individuals). Rates of bidirectional versus unidirectional violence (male-toward-female vs. female-toward-male) were summarized directly as reported or were derived on the basis of data contained within the article.
All obtained studies (48 empirical, 1 meta-analysis, 1 book chapter) were then entered into an online summary table for public review; however, additional results were specifically calculated for the current article. These results indicate that bidirectional violence was common across all types of samples (population-based to criminal justice). This suggests that the role of women in violent relationships is important to consider, even if all aspects of women's perpetration of IPV are not symmetrical to men's perpetration of IPV. A second finding to emerge was that the ratio of unidirectional female-to-male compared to male-to-female IPV differed significantly among samples with higher rates of female-perpetrated unidirectional violence found in four of the five sample types considered. Higher ratios of male-to-female unidirectional violence were found only in criminal justice/legal studies that relied on police reports of IPV perpetration and/or in samples drawn from the U.S. military. Competing explanations for the differing ratios were offered in the current discussion. These need to be tested empirically in order to fully understand the expression of IPV across samples and settings. Differences in the directionality of the expression of IPV were not found in samples of gay, lesbian, or bisexual individuals; however, rates of bidirectional violence appear to vary by race/ethnicity with higher rates of bidirectional violence among Black couples. Overall, it is suggested that if one resolution of the gender symmetry/asymmetry debate is to argue that there are subtypes of male and female domestic violence perpetrators (Johnson, 2005; Johnson, 2006), or that there are different patterns of violence among different types of relationships characterized by IPV (Stets & Straus, 1989), researchers and clinicians will need to work together to determine how to reliably and meaningfully make these determinations in ways that will facilitate our ability to effectively prevent and treat all types of IPV.
Objective: To determine if similar levels of performance on the Overall Test Battery Mean (OTBM) occur at different forced choice test (FCT) p-value score failures. Second, to determine the OTBM ...levels that are associated with failures at above chance on various performance validity (PVT) tests. Method: OTBMs were computed from archival data obtained from four practices. We calculated each examinee's Estimated Premorbid Global Ability (EPGA) and OTBM. The sample size was 5,103 examinees with 282 (5.5%) of these scoring below chance at p ≤ .20 on at least one FCT. Results: The OTBM associated with a failure at p ≤ .20 was equivalent to the OTBM that was associated with failing 6 or more PVTs at above-chance cutoffs. The mean OTBMs relative to increasingly strict FCT p cutoffs were similar (T scores in the 30s). As expected, there was an inverse relationship between the number of PVTs failed and examinees' OTBMs. Conclusions: The data support the use of p ≤ .20 as the probability level for testing the significance of below chance performance on FCTs. The OTBM can be used to index the influence of invalid performance on outcomes, especially when an examinee scores below chance.
The meta-analytic findings of Binder et al. (1997) and Frencham et al. (2005) showed that the neuropsychological effect of mild traumatic brain injury (mTBI) was negligible in adults by 3 months post ...injury. Pertab et al. (2009) reported that verbal paired associates, coding tasks, and digit span yielded significant differences between mTBI and control groups. We re-analyzed data from the 25 studies used in the prior meta-analyses, correcting statistical and methodological limitations of previous efforts, and analyzed the chronicity data by discrete epochs. Three months post injury the effect size of −0.07 was not statistically different from zero and similar to that which has been found in several other meta-analyses (Belanger et al., 2005; Schretlen & Shapiro, 2003). The effect size 7 days post injury was −0.39. The effect of mTBI immediately post injury was largest on Verbal and Visual Memory domains. However, 3 months post injury all domains improved to show non-significant effect sizes. These findings indicate that mTBI has an initial small effect on neuropsychological functioning that dissipates quickly. The evidence of recovery in the present meta-analysis is consistent with previous conclusions of both Binder et al. and Frencham et al. Our findings may not apply to people with a history of multiple concussions or complicated mTBIs.
The current study utilizes five decades of data to demonstrate cohort differences in gender representation in governance, speaking at conferences, serving on editorial boards, and in scholarly ...productivity in clinical neuropsychology. Broadly examining gender disparities across domains of professional attainment helps illuminate the areas in which inequity in clinical neuropsychology is most pronounced and in need of ameliorative resources.
Data from 1967 to 2017 were coded from publicly available information from the four major professional associations for clinical neuropsychology in the U.S. (i.e. INS, AACN, NAN, & SCN). Gender differences were examined in (1) speaking at a national conference, (2) holding an office in a professional organization, (3) serving on the editorial team for a journal affiliated with a professional organization, and (4) scholarly activity as coded from Google Scholar.
The percentage of men in the field significantly declined across time, whereas the percentage of women significantly increased; the number of women exceeded the number of men in approximately 1992. Gender differences in conference speakers, editorial board members, and research citations were greater in the earlier than in more recent cohorts of clinical neuropsychologists but gender inequity in conference speaking and editorial activities is evident in the most recent cohorts.
Gender differences in conference speakers, editorial board members, and in earning research citations have diminished over time, but early career women still face disadvantages in speaking at conferences and serving on editorial boards. We provide strategies to increase and sustain women's participation in leadership in neuropsychology.
The primary purpose of this study was to determine the individual, family, and peer factors that correlate with adolescent gambling. High school students from three states ( N = 1,846) completed an ...anonymous questionnaire assessing the behavior of themselves, their parents, and their peers. Participants also reported on their gambling behavior via the SOGS-RA, which was used to create five adolescent gambling groups (i.e., Non-Gamblers, Non-Problem Gamblers, At-Risk Gamblers, Problem Gamblers, and Probable Pathological Gamblers). In a discriminant function analysis using demographic, individual, family, and peer factors as potential discriminators, two functions emerged that accounted for 94% of the variance between groups. The first function was linear, with the Probable Pathological Gamblers reporting the highest level of peer and parent gambling, susceptibility to peer pressure, conduct problems, binge drinking, suicide attempts, drug use, and being male. The second function highlighted three unique qualities of individuals in the two outlying groups: Probable Pathological Gamblers and Non-Gamblers. These findings suggest that demographic, individual, family, and peer variables are all important correlates of probable pathological gambling in adolescents. Results also support the utility of a five-group classification scheme based on the SOGS-RA. The clinical implications of these results are discussed.
