A survey of neuropsychologists’ use of validity tests with children and adolescents

A web-based survey of validity test use by North American neuropsychologists was conducted, with 282 participants meeting inclusion criteria. Respondents indicated that they use a median of one stand-alone performance validity test (PVT), one embedded PVT, and one symptom validity test (SVT) per pediatric assessment. The vast majority of respondents indicated they give at least one PVT (92%) and at least one SVT (88%) during each pediatric assessment. A meaningful difference in validity use (i.e., at least a medium effect size) was only found for those who engage in forensic work, with those clinicians giving more stand-alone PVTs than those who do not conduct forensic work. The most frequently used validity measures in pediatric assessments are presented, as are reasons participants reported for both using and not using validity tests. Limitations and qualitative comparisons to other surveys on validity test use with adults are discussed.     

Perfectionism in young musicians: Relations with motivation, effort, achievement, and distress

Many musicians experience anxiety and distress when performing, which has been related to perfectionism. Recent findings, however, show that only some facets of perfectionism are associated with anxiety and distress, whereas other facets are associated with positive characteristics and outcomes such as motivation and achievement. To investigate how different facets of perfectionism are related to motivation, effort, achievement, and distress in musicians, 146 young musicians completed measures of perfectionism (striving for perfection, negative reactions to imperfection, and perceived pressure to be perfect), intrinsic and extrinsic motivation, effort, achievement, and distress. Results showed that striving for perfection was associated with intrinsic motivation (intrinsic/identified reasons), higher effort, and higher achievement. Whereas perceived pressure from music teachers was also associated with intrinsic motivation (identified reasons only), negative reactions to imperfection were associated with extrinsic motivation and higher distress. The findings demonstrate that perfectionism in musicians has both positive and negative sides. While negative reactions to imperfection are clearly unhealthy, striving for perfection may be regarded as a healthy pursuit of excellence.     

The IKEA effect: When labor leads to love

In four studies in which consumers assembled IKEA boxes, folded origami, and built sets of Legos, we demonstrate and investigate boundary conditions for the IKEA effect—the increase in valuation of self-made products. Participants saw their amateurish creations as similar in value to experts' creations, and expected others to share their opinions. We show that labor leads to love only when labor results in successful completion of tasks; when participants built and then destroyed their creations, or failed to complete them, the IKEA effect dissipated. Finally, we show that labor increases valuation for both “do-it-yourselfers” and novices.     

Doing bad through being selective in doing good: the role of within-unit variability in ethical leadership

Although it is commonly assumed that perceptions of equity at work have a significant impact on employee absenteeism, our understanding of the equity–absence relationship is limited in that (1) little is known about equity concepts other than procedural and distributive justice; and (2) for the most part, research has overlooked variables likely to mediate and moderate the impact of equity on absenteeism. Drawing from the effort–reward imbalance model (ERI; Siegrist, 1996), our study advances past research by investigating the association between status inconsistency (a situation in which there is a mismatch between, for example, a person's education and his/her income) and absenteeism, and the variables likely to account for this association. Results from a sample of 416 customer-care employees show that stress mediates the relationship between status inconsistency and absenteeism, and that HRM practices attenuate this relationship. Moderated mediation analyses further reveal that HRM practices moderate the indirect effect of status inconsistency on absenteeism via stress.     

Effort denial in self-deception

We propose a mixed belief model of self-deception. According to the theory, people distribute belief over two possible causal paths to an action, one where the action is freely chosen and one where it is due to factors outside of conscious control. Self-deceivers take advantage of uncertainty about the influence of each path on their behavior, and shift weight between them in a self-serving way. This allows them to change their behavior to provide positive evidence and deny doing so, enabling diagnostic inference to a desired trait. In Experiment 1, women changed their pain tolerance to provide positive evidence about the future quality of their skin, but judgments of effort claimed the opposite. This “effort denial” suggests that participants’ mental representation of their behavior was dissociated from their actual behavior, facilitating self-deception. Experiment 2 replicated the pattern in a hidden picture task where search performance was purportedly linked to self-control.     

Working Hard to Take the Easy Way Out: How the Need for Cognitive Closure Shapes Strategic Effort Investment to Ease Future Decision Making

Consumers make countless decisions each day that force them to determine the amount of effort they are willing to invest into the decision process. Due to their desire for immediate resolution and propensity to seize upon available options, individuals high in the need for cognitive closure make decisions that are traditionally associated with reduced effort investment. Counter to this traditional perspective, this research demonstrates that those seeking closure strategically invest effort into the decision process, so long as the initial effort investment is expected to simplify similar decisions in the future. Three experiments demonstrate that those motivated by closure put forth greater effort when they expect to repeat the decision (Experiment 1) and in contexts where a justifiable choice option is not readily available (Experiment 2). Furthermore, this effort investment is shown to payoff in terms of streamlining subsequent decision making (Experiment 3). These findings detail the strategic use of effort by those seeking closure to ease future decision making and thus provide a conceptual framework for when and why those seeking closure allocate effort in decision making.     

Wisconsin Card Sorting Test embedded validity indicators developed for adults can be extended to children

Past studies have examined the ability of the Wisconsin Card Sorting Test (WCST) to discriminate valid from invalid performance in adults using both individual embedded validity indicators (EVIs) and multivariate approaches. This study is designed to investigate whether the two most stable of these indicators—failures to maintain set (FMS) and the logistical regression equation S-B_LRE—can be extended to pediatric populations.

The classification accuracy for FMS and S-B_LRE was examined in a mixed clinical sample of 226 children aged 7 to 17 years (64.6% male, MAge = 13.6 years) against a combination of established performance validity tests (PVTs).

The results show that at adult cutoffs, FMS and S-B_LRE produce an unacceptably high failure rate (33.2% and 45.6%) and low specificity (.55–.72), but an upward adjustment in cutoffs significantly improves classification accuracy. Defining Pass as <2 and Fail as ≥4 on FMS results in consistently good specificity (.89–.92) but low and variable sensitivity (.00–.33). Similarly, cutting the S-B_LRE distribution at 3.68 produces good specificity (.90–.92) but variable sensitivity (.06–.38). Passing or failing FMS or S-B_LRE is unrelated to age, gender and IQ.

The data from this study suggest that in a pediatric sample, adjusted cutoffs on the FMS and S-B_LRE ensure good specificity, but with low or variable sensitivity. Thus, they should not be used in isolation to determine the credibility of a response set. At the same time, they can make valuable contributions to pediatric neuropsychology by providing empirically-supported, expedient and cost-effective indicators to enhance performance validity assessment.     

Assessing Effort During Neuropsychological Evaluation with the TOMM in Children and Adolescents with Epilepsy

Effort assessment is of particular importance in pediatric epilepsy where neuropsychological findings may influence treatment decisions, especially if surgical interventions are being considered. The present investigation examines the Test of Memory Malingering (TOMM) in 60 children and adolescents with epilepsy. The overall pass rate for the sample was 90%. TOMM scores were unrelated to age, though there was a significant correlation between TOMM Trial 2 scores and intelligence estimates. Overall, the TOMM appears to be a valid measure of effort in young epilepsy patients, though caution should be used when interpreting scores for those with very low IQ, especially if behavioral problems are also evident. Caution should also be exercised in interpreting scores in children with ongoing interictal epileptiform activity that may disrupt attention.     

Children and the Test of Memory Malingering: Is one trial enough?

There is a growing body of research suggesting that the first trial of the TOMM may provide an accurate screener of effort in children. During neuropsychological assessments, some circumstances result in only one completed trial of the TOMM. Research on adults reflects that passing scores on Trial 1 (based on Trial 2 cutoff) are highly predictive of passing scores on Trial 2 and the TOMM overall. Pediatric research found that 100% of children and adolescents who passed Trial 1 of the TOMM also passed Trial 2. Our research hypothesis is that children who pass Trial 1 will also pass Trial 2. Data from 75 clinically diagnosed children (ages 6–18 years) found that 64% performed above the published adult TOMM cutoff on Trial 1. All children who passed Trial 1 also passed Trial 2 suggesting support for the research hypothesis. Sensitivity was 1.0, specificity was 0.72, positive predictive value was .33, and negative predictive value was 1.0. These findings suggest that in this sample, the children who performed above the Trial 2 cutoff on Trial 1 also all passed Trial 2 (so there were no false negatives, thus a perfect sensitivity and negative predictive value). Of the 36% of children who did not pass the Trial 1 cutoff, 67% passed on Trial 2. Data clearly support that children passing Trial 1 have a high likelihood of passing Trial 2, thus drawing conclusions about performance validity after passing Trial 1. Conclusions after failing Trial 1 require further investigation.
