Abstract:This investigation assessed the role of the Big Five dimensions of personality and perfectionism in predicting nonsuicidal cutting in a sample of undergraduate students. Of 292 students, 50 (17%) endorsed cutting behavior. Duration of cutting was associated with Openness, and Introversion, as well as perfectionistic rumination. Frequency of cutting was associated with Conscientiousness, Agreeableness, low Neuroticism (accounting for about 20% of the variance), as well as perfectionistic rumination, organization, and low concern over mistakes (accounting for 31% of the variance). These findings are discussed in the context of previous research investigations of risk factors for nonsuicidal self-injury (NSSI) that are convergent, and sometimes discrepant with these data. The findings suggest that more research into personality traits and methods of NSSI is warranted.
Embedded validity measures support comprehensive assessment of performance validity. The purpose of this study was to evaluate the accuracy of individual embedded measures and to reduce them to the most efficient combination. The sample included 212 postdeployment veterans (average age = 35 years, average education = 14 years). Thirty embedded measures were initially identified as predictors of Green's Word Memory Test (WMT) and were derived from the California Verbal Learning Test-Second Edition (CVLT-II), Conners' Continuous Performance Test-Second Edition (CPT-II), Trail Making Test, Stroop, Wisconsin Card Sorting Test-64, the Wechsler Adult Intelligence Scale-Third Edition Letter-Number Sequencing, Rey Complex Figure Test (RCFT), Brief Visuospatial Memory Test-Revised, and the Finger Tapping Test. Eight nonoverlapping measures with the highest area-under-the-curve (AUC) values were retained for entry into a logistic regression analysis. Embedded measure accuracy was also compared to cutoffs found in the existing literature. Twenty-one percent of the sample failed the WMT. Previously developed cutoffs for individual measures showed poor sensitivity (SN) in the current sample except for the CPT-II (Total Errors, SN = .41). The CVLT-II (Trials 1-5 Total) showed the best overall accuracy (AUC = .80). After redundant measures were statistically eliminated, the model included the RCFT (Recognition True Positives), CPT-II (Total Errors), and CVLT-II (Trials 1-5 Total) and increased overall accuracy compared with the CVLT-II alone (AUC = .87). The combination of just 3 measures from the CPT-II, CVLT-II, and RCFT was the most accurate/efficient in predicting WMT performance.
This study explored the association between number of methods of Nonsuicidal Self-Injury (NSSI) and personality, psychopathology, and functions of NSSI. Two combined undergraduate samples reporting a history of NSSI (n = 149) completed measures of personality, psychopathology, and NSSI. A series of regression analyses indicated that Conscientiousness, Openness, and two functions of NSSI (i.e., Automatic Negative Reinforcement and Social Negative Reinforcement) shared significant relationships with the number of NSSI methods participants engaged in. These findings demonstrate that, after accounting for NSSI frequency, a relationship exists among specific personality factors, NSSI functions, and engagement in additional methods of NSSI.
Neuropsychology practice organizations have highlighted the need for thorough evaluation of performance validity as part of the neuropsychological assessment process. Embedded validity indices are derived from existing measures and expand the scope of validity assessment. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a brief instrument that quickly allows a clinician to assess a variety of cognitive domains. The RBANS also contains multiple embedded validity indicators. The purpose of this study was to synthesize the utility of those indicators to assess performance validity. A systematic search was completed, resulting in 11 studies for synthesis and 10 for meta-analysis. Data were synthesized on four indices and three subtests across samples of civilians, service members, and veterans. Sufficient data for meta-analysis were only available for the Effort Index, and related analyses indicated optimal cutoff scores of ≥1 (AUC = .86) and ≥ 3 (AUC = .85). However, outliers and heterogeneity were present indicating the importance of age and evaluation context. Overall, embedded validity indicators have shown adequate diagnostic accuracy across a variety of populations. Recommendations for interpreting these measures and future studies are provided.
Objective: Mild traumatic brain injury (TBI) that occurs in a deployment environment is characteristically different from mild TBI that occurs outside of deployment. This study evaluated differential and interaction effects of deployment and nondeployment mild TBI on cognitive and behavioral health outcomes. Research Method: Combat veterans (N ϭ 293) who passed performance-validity measures completed the Mid-Atlantic MIRECC Assessment of TBI (MMA-TBI), Clinician-Administered Posttraumatic Stress Disorder (PTSD) Scale (CAPS-5), a neuropsychological assessment battery, and self-report questionnaires. A 2 ϫ 2 ϫ 2 analysis of variance (ANOVA) was conducted to evaluate the main and interaction effects across mild TBI groups and PTSD diagnosis. Results: Deployment TBI was associated with poorer outcomes on several cognitive tests: Wechsler Adult Intelligence Scale, 4th edition (WAIS-IV); Working Memory Index (WMI; p ϭ .018); Trail Making Test A (TMT-A; p Ͻ .001); and Trail Making Test B (TMT-B; p ϭ .002). Deployment TBI and PTSD were also associated with increased PTSD, depressive, and neurobehavioral symptoms; pain interference; and poorer sleep quality. Nondeployment TBI had no effect on cognitive performance and was associated only with poorer sleep quality. PTSD had the strongest associations with symptom measures and deployment TBI with cognitive outcomes. There were no significant interaction effects after adjusting for multiple comparisons. Conclusions: Remote outcomes associated with mild deployment TBI are different from those associated with nondeployment mild TBI and are robust beyond PTSD. This suggests that the environment surrounding a TBI event influences cognitive and symptom sequelae. Veterans who experience mild TBI during deployment may report changes in cognition, but most will continue to function within the expected range. Impact and ImplicationsMild deployment traumatic brain injury (TBI) was associated with lower performance on measures of attention and processing speed. Veterans who experience mild TBI during deployment may be more likely to report changes in cognition to providers. Although most will function in an expected range, implementation of skill building, compensatory strategies, and patient education about recovery from mild TBI may be beneficial in supporting recovery.
Little is known about attention-deficit/hyperactivity disorder (ADHD) in veterans. Practice standards recommend the use of both symptom and performance validity measures in any assessment, and there are salient external incentives associated with ADHD evaluation (stimulant medication access and academic accommodations). The purpose of this study was to evaluate symptom and performance validity measures in a clinical sample of veterans presenting for specialty ADHD evaluation. Patients without a history of a neurocognitive disorder and for whom data were available on all measures (n = 114) completed a clinical interview structured on DSM-5 ADHD symptoms, the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF), and the Test of Memory Malingering Trial 1 (TOMM1) as part of a standardized ADHD diagnostic evaluation. Veterans meeting criteria for ADHD were not more likely to overreport symptoms on the MMPI-2-RF nor to fail TOMM1 (score ≤ 41) compared with those who did not meet criteria. Those who overreported symptoms did not endorse significantly more ADHD symptoms; however, those who failed TOMM1 did report significantly more ADHD symptoms (g = 0.90). In the total sample, 19.3% failed TOMM1, 44.7% overreported on the MMPI-2-RF, and 8.8% produced both an overreported MMPI-2-RF and invalid TOMM1. F-r had the highest correlation to TOMM1 scores (r = -.30). These results underscore the importance of assessing both symptom and performance validity in a clinical ADHD evaluation with veterans. In contrast to certain other conditions (e.g., mild traumatic brain injury), ADHD as a diagnosis is not related to higher rates of invalid report/performance in veterans. (PsycINFO Database Record
