Using the MMPI-2-RF, IOP-29, IOP-M, and FIT in the In-Person and Remote Administration Formats: A Simulation Study on Feigned mTBI.

Our study compared the impact of administering Symptom Validity Tests (SVTs) and Performance Validity Tests (PVTs) in in-person versus remote formats and assessed different approaches to combining validity test results. Using the MMPI-2-RF, IOP-29, IOP-M, and FIT, we assessed 164 adults, with half instructed to feign mild traumatic brain injury (mTBI) and half to respond honestly. Within each subgroup, half completed the tests in person, and the other half completed them online via videoconferencing. Results from 2 ×2 analyses of variance showed no significant effects of administration format on SVT and PVT scores. When comparing feigners to controls, the MMPI-2-RF RBS exhibited the largest effect size (d = 3.05) among all examined measures. Accordingly, we conducted a series of two-step hierarchical logistic regression models by entering the MMPI-2-RF RBS first, followed by each other SVT and PVT individually. We found that the IOP-29 and IOP-M were the only measures that yielded incremental validity beyond the effects of the MMPI-2-RF RBS in predicting group membership. Taken together, these findings suggest that administering these SVTs and PVTs in-person or remotely yields similar results, and the combination of MMPI and IOP indexes might be particularly effective in identifying feigned mTBI.

Rorschach Human Movement and Psychotherapy: Relationship with the Therapist's Emotional Responses.

The emotional responses of psychotherapists to their patients, known as countertransference, can yield valuable insights into the patient's psychological functioning. Albeit from a different perspective, the Rorschach test also provides information about the patient's psychological processes. In particular, the Rorschach human movement response (M) has been shown to be a useful measure of higher-level psychological functioning. In an attempt to bridge these two largely different perspectives, the aim of this study was to explore the association between M responses in the Rorschach protocols of psychotherapy patients and emotional responses exhibited by their therapists. To this end, a convenience sample of 149 outpatients were administered the Rorschach according to the Comprehensive System, and their therapists completed the Therapist Response Questionnaire. Through a series of regression models, controlling for response style, response complexity, and degree of psychopathology, M demonstrated a significant association with the therapists' emotional responses. A lower number of M responses was associated with the therapists' feelings of disengagement, and a higher number of M responses was associated with the therapists' feelings of being more involved with the patient. Taken together, these results suggest a potential relationship between the number of M responses the respondent gives in the Rorschach and the subsequent development of the therapeutic alliance between the respondent and their therapist.

Replicating the classification accuracy of the Verbal Paired Associates and Visual Reproduction recognition trials as embedded performance validity tests.

OBJECTIVE: This study was designed to replicate previous research on the clinical utility of the Verbal Paired Associates (VPA) and Visual Reproduction (VR) subtests of the WMS-IV as embedded performance validity tests (PVTs) and perform a critical item (CR) analysis within the VPA recognition trial. METHOD: Archival data were collected from a mixed clinical sample of 119 adults (MAge = 42.5, MEducation = 13.9). Classification accuracy was computed against psychometrically defined criterion groups based on the outcome of various free-standing and embedded PVTs. RESULTS: Age-corrected scaled scores ≤ 6 were specific (.89-.98) but had variable sensitivity (.36-.64). A VPA recognition cutoff of ≤ 34 produced a good combination of sensitivity (.46-.56) and specificity (.92-.93), as did a VR recognition cutoff of ≤ 4 (.48-.53 sensitivity at .86-.94 specificity). Critical item analysis expanded the VPA's sensitivity by 3.5%-7.0% and specificity by 5%-8%. Negative learning curves (declining output on subsequent encoding trials) were rare but highly specific (.99-1.00) to noncredible responding. CONCLUSIONS: Results largely support previous reports on the clinical utility of the VPA and VR as embedded PVTs. Sample-specific fluctuations in their classification accuracy warrant further research into the generalizability of the findings. Critical item analysis offers a cost-effective method for increasing confidence in the interpretation of the VPA recognition trial as a PVT.

Effects of Covid-19 Emergency and Associated Lockdown Policies on the Normative Expectations for the Personality Assessment Inventory (PAI) and the Rorschach Performance Assessment System (R-PAS).

Standardized personality tests compare the test taker's scores to those of a large sample of individuals representing normative expectations. However, what is psychologically normal in one historical context may not be similarly normal in another, so the recent spread of a new coronavirus, SARS-Cov-2 (COVID-19), may have implications for what should normally be expected of a nonclinical person taking a personality test shortly after this dramatic event. To address this research question, we administered the Personality Assessment Inventory (PAI) and the Rorschach Performance Assessment System (R-PAS) to 60 nonclinical volunteers from Italy and compared their scores with the official normative reference values of the two tests, which had been established before COVID-19. The results of a series of two-sample t-tests indicated that our newly collected sample appeared somewhat less psychologically healthy compared with normative expectations, and these discrepancies were more pronounced on the PAI than on the R-PAS. Implications and future perspectives are discussed.

The ecological validity of the IOP-29: A follow-up study using the MMPI-2-RF and the SIMS as criterion variables.

Current guidelines for conducting symptom validity assessments require that professionals administer multiple symptom validity tests (SVTs) and that the SVTs selected for their evaluations provide nonredundant information. However, not many SVTs are currently available, and most of them rely on the same, (in)frequency-based, feigning detection strategy. In this context, the Inventory of Problems (IOP-29) could be a valuable addition to the assessor's toolbox because of its brevity (29 items) and its different approach to assessing the credibility of presented symptoms. As its ecological validity has been poorly investigated, the present study used a criterion groups design to examine the classification accuracy of the IOP-29 in a data set of 174 court-ordered psychological evaluations focused on psychological injury. The validity scales of the Minnesota Multiphasic Personality Inventory-2 Restructured Form and the total score of the Structured Inventory of Malingered Symptoms were used as criterion variables. Overall, the results of this study confirm that the IOP-29 is an effective measure (1.70 ≤ d ≤ 2.67) that provides valuable information when added to the multimethod assessment of symptom validity in civil forensic contexts.

Can static Rorschach stimuli perceived as in motion affect corticospinal excitability?

It has been proposed that seeing human movement or activity (M), while trying to say what the static Rorschach inkblot design look like, is accompanied by Mirror Neuron System (MNS)-like mirroring activity in the brain. The present study aimed to investigate whether the Rorschach cards eliciting M responses could affect the excitability of the motor cortex by recording motor evoked potentials (MEPs) elicited by single-pulse TMS over the primary motor cortex (M1). We hypothesized that Rorschach inkblot stimuli triggering the viewer's experience of human movement would increase corticospinal excitability. Twenty-one healthy volunteers (15 women) participated in the preliminary experiment, while another different sample of twenty-two healthy participants (11 women) ranging in age from 21 to 41 years was enrolled in the main experiment. Our results showed that the Rorschach cards known to be associated with a high number of M responses elicited human movement both as automatic internal sensations and as verbal production of responses involving human movement. However, contrary to our hypothesis, the reported internal feeling of human movement had no corresponding physiological counterpart, as the amplitude of MEPs did not increase. Possible and innovative explanations for the involvement of bottom-up and top-down processes were provided.

Logical memory, visual reproduction, and verbal paired associates are effective embedded validity indicators in patients with traumatic brain injury.

OBJECTIVE: This study was design to evaluate the potential of the recognition trials for the Logical Memory (LM), Visual Reproduction (VR), and Verbal Paired Associates (VPA) subtests of the Wechsler Memory Scales-Fourth Edition (WMS-IV) to serve as embedded performance validity tests (PVTs). METHOD: The classification accuracy of the three WMS-IV subtests was computed against three different criterion PVTs in a sample of 103 adults with traumatic brain injury (TBI). RESULTS: The optimal cutoffs (LM ≤ 20, VR ≤ 3, VPA ≤ 36) produced good combinations of sensitivity (.33-.87) and specificity (.92-.98). An age-corrected scaled score of ≤5 on either of the free recall trials on the VPA was specific (.91-.92) and relatively sensitive (.48-.57) to psychometrically defined invalid performance. A VR I ≤ 5 or VR II ≤ 4 had comparable specificity, but lower sensitivity (.25-.42). There was no difference in failure rate as a function of TBI severity. CONCLUSIONS: In addition to LM, VR, and VPA can also function as embedded PVTs. Failing validity cutoffs on these subtests signals an increased risk of non-credible presentation and is robust to genuine neurocognitive impairment. However, they should not be used in isolation to determine the validity of an overall neurocognitive profile.

Cross-cultural investigation from nine countries on the associations of antisocial traits and the WHO's containment measures for the COVID-19 pandemic.

Personality traits play a role in prosocial behavior in relation to containment measures intended to tackle the COVID-19 pandemic. Empirical findings indicated that individuals high in socially aversive traits such as callousness are less compliant with containment measures. This study aimed to add cross-cultural data on the relationship between antisocial traits and adherence to COVID-19 containment measures. The sample consisted of 4,538 adults recruited by convenience in nine countries (Australia, Brazil, England, Iraq, Iran, Italy, Jordan, Saudi Arabia, and the United States). Statistical analyses indicated two latent profiles from our sample, empathic and antisocial, and six COVID-19 containment-measure-related factors using measures covering antisocial traits (PID-5), empathy (ACME), global personality pathology (LPFS-BF), and COVID-19 behaviors and beliefs. Through MANCOVA, the antisocial profile consistently showed less compliance and concern about the COVID-19 containment measures, even when controlling for demographics and local pandemic covariables. The network analysis indicated a lack of empathy and callousness as crucial traits of the predisposition to non-compliant behavior. In elaborating on prosocial campaigns in community emergencies, our cross-cultural findings would need to consider personality traits that focus on antisociality, anticipating similar associations and potential impacts in future disease outbreaks.

Detection of Feigning of Different Symptom Presentations With the PAI and IOP-29.

This study examined the effectiveness of the negative distortion measures from the Personality Assessment Inventory (PAI) and Inventory of Problems-29 (IOP-29), by investigating data from a community and a forensic sample, across three different symptom presentations (i.e., feigned depression, posttraumatic stress disorder [PTSD], and schizophrenia). The final sample consisted of 513 community-based individuals and 288 inmates (total N = 801); all were administered the PAI and the IOP-29 in an honest or feigning conditions. Statistical analyses compared the average scores of each measure by symptom presentation and data source (i.e., community vs. forensic sample) and evaluated diagnostic efficiency statistics. Results suggest that the PAI Negative Impression Management scale and the IOP-29 are the most effective measures across all symptom presentations, whereas the PAI Malingering Index and Rogers Discriminant Function generated less optimal results, especially when considering feigned PTSD. Practical implications are discussed.

The sensitivity of the IOP-29 and IOP-M to coached feigning of depression and mTBI: An online simulation study in a community sample from the United Kingdom.

Assessing the credibility of symptoms is critical to neuropsychological assessment in both clinical and forensic settings. To this end, the Inventory of Problems-29 (IOP-29) and its recently added memory module (Inventory of Problems-Memory; IOP-M) appear to be particularly useful, as they provide a rapid and cost-effective measure of both symptom and performance validity. While numerous studies have already supported the effectiveness of the IOP-29, research on its newly developed module, the IOP-M, is much sparser. To address this gap, we conducted a simulation study with a community sample (N = 307) from the United Kingdom. Participants were asked to either (a) respond honestly or (b) pretend to suffer from mTBI or (c) pretend to suffer from depression. Within each feigning group, half of the participants received a description of the symptoms of the disorder to be feigned, and the other half received both a description of the symptoms of the disorder to be feigned and a warning not to over-exaggerate their responses or their presentation would not be credible. Overall, the results confirmed the effectiveness of the two IOP components, both individually and in combination.

Markers of emotion regulation processes: A neuroimaging and behavioral study of reappraising abilities.

Emotion regulation (ER) is a core element for individual well-being, and dysregulated emotional states are prominent in several mental disorders. Moreover, dispositional use of adaptive ER strategies, such as cognitive reappraisal, is usually associated to better psychological outcomes and less emotional problems. Thus, identifying markers of emotion dysregulation could serve as a key point for developing treatments against risks of psychopathological outcomes. Neuroimaging techniques could represent a useful tool within these aims, focusing on neurobiological markers of psychopathological illness. Given the well known gender differences in using ER strategies, we examined behavioral and neuroimaging patterns associated with dispositional use of reappraisal among a non-clinical female sample. We found that the individual predisposition to use cognitive reappraisal as an emotion regulation strategy was associated with decreased levels of dysregulation. From a neurobiological perspective, difficulties in using reappraisal were associated with decreased resting-state functional connectivity (rs-FC) between the Middle Temporal Gyrus and occipito-parietal regions. Moreover, rs-FC between prefrontal and occipito-parietal brain regions was negatively associated with emotion dysregulation levels. Microstructural anomalies across white matter tracts connecting temporal, parietal, and occipital brain regions were associated to difficulties in using reappraisal. Our findings suggest that specific behavioral and neurobiological substrates are linked to reappraising abilities. Furthermore, the ability to implement adaptive ER strategies could serve as protective factor against developing emotion dysregulation.

Symptom coaching and symptom validity tests: An analog study using the structured inventory of malingered symptomatology, Self-Report Symptom Inventory, and Inventory of Problems-29.

In this pilot and exploratory study, we tested the robustness of three self-report symptom validity tests (SVTs) to symptom coaching for depression, with and without additional information available on the Internet. Specifically, we divided our sample (N = 193) so that each subject received either the Structured Inventory of Malingered Symptomatology (SIMS; n = 64), the Self-Report Symptom Inventory (SRSI; n = 66), or the Inventory of Problems-29 (IOP-29; n = 63). Within each of the three subgroups, approximately one third of participants were instructed to respond honestly (Genuine Condition, nSIMS = 21; nSRSI = 24; nIOP-29 = 26) and approximately two-thirds were instructed to feign depression. One half of the feigners were presented with a vignette to increase their compliance with instructions and were given information about symptoms of depression (Coached Feigning, nSIMS = 25; nSRSI = 18; nIOP-29 = 21), and the other half were given the same vignette and information about symptoms of depression, plus two Internet links to review before completing the test (Internet-Coached Feigning, nSIMS = 18; nSRSI = 24; nIOP-29 = 16). Overall, the results showed that the genuine conditions yielded the lowest total scores on all three measures, while the two feigning conditions did not significantly differ from each other. Looking at the detection rates for all feigning participants, all three measures showed satisfactory results, with IOP-29 performing slightly better than SIMS and SIMS performing slightly better than SRSI. Internet-Coached Feigners scored slightly lower on all three measures than feigners who were coached without the Internet links. Taken together, the results of this preliminary and exploratory study suggest that all three SVTs examined are sensitive to feigned depression even in the presence of symptom coaching, both with and without additional Internet-based information.

Can the Rorschach be Administered Remotely? A Review of Options and a Pilot Study Using a Newly Developed R-PAS App.

The ongoing COVID-19 pandemic has required psychologists to adopt measures like physical distancing and mask wearing, though other safety procedures such as travel restrictions or prohibitions on in-person practice and research have fostered the use of tele-health tools. In this article, we review options for using the Rorschach task via videoconference and provide preliminary data from using a new electronic app for remote R-PAS administration to determine whether the remote administration in an electronic form yields different information than in-person administration with the cards in hand. As a pilot study, our focus is on the "first factor" of all Rorschach scores, i.e., complexity. Data were collected from 60 adult Italian community volunteers, and statistical analyses evaluated the extent to which the average complexity score significantly departed from R-PAS normative expectations (SS = 100), accompanied by Bayesian likelihoods for supporting the null hypothesis. Results suggest that the general level of complexity shown by the test-takers when administered the Rorschach remotely with the new R-PAS app closely resembles that previously observed using "standard" in-person procedures. Tentative analyses of other R-PAS scores suggested normative departures that could be due to the effects of the app, testing at home, or responses to the pandemic. We offer recommendations for future research and discuss practical implications.

An Australian study on feigned mTBI using the Inventory of Problems - 29 (IOP-29), its Memory Module (IOP-M), and the Rey Fifteen Item Test (FIT).

We investigated the classification accuracy of the Inventory of Problems - 29 (IOP-29), its newly developed memory module (IOP-M) and the Fifteen Item Test (FIT) in an Australian community sample (N = 275). One third of the participants (n = 93) were asked to respond honestly, two thirds were instructed to feign mild TBI. Half of the feigners (n = 90) were coached to avoid detection by not exaggerating, half were not (n = 92). All measures successfully discriminated between honest responders and feigners, with large effect sizes (d ≥ 1.96). The effect size for the IOP-29 (d ≥ 4.90), however, was about two-to-three times larger than those produced by the IOP-M and FIT. Also noteworthy, the IOP-29 and IOP-M showed excellent sensitivity (>90% the former, > 80% the latter), in both the coached and uncoached feigning conditions, at perfect specificity. Instead, the sensitivity of the FIT was 71.7% within the uncoached simulator group and 53.3% within the coached simulator group, at a nearly perfect specificity of 98.9%. These findings suggest that the validity of the IOP-29 and IOP-M should generalize to Australian examinees and that the IOP-29 and IOP-M likely outperform the FIT in the detection of feigned mTBI.

Symptom and Performance Validity Assessment in European Countries: an Update.

In 2013, a special issue of the Spanish journal Clínica y Salud published a review on symptom and performance validity assessment in European countries (Merten et al. in Clínica y Salud, 24(3), 129-138, 2013). At that time, developments were judged to be in their infancy in many countries, with major publication activities stemming from only four countries: Spain, The Netherlands, Great Britain, and Germany. As an introduction to a special issue of Psychological Injury and Law, this is an updated report of developments during the last 10 years. In that period of time, research activities have reached a level where it is difficult to follow all developments; some validity measures were newly developed, others were adapted for European languages, and validity assessment has found a much stronger place in real-world evaluation contexts. Next to an update from the four nations mentioned above, reports are now given from Austria, Italy, and Switzerland, too.

A clinical comparison simulation study using the Inventory of Problems-29 (IOP-29) with the Center for Epidemiologic Studies Depression Scale (CES-D) in Lithuania.

This article contributes to the growing research on the validity of the recently developed, Inventory of Problems - 29 (IOP-29) in the discrimination of feigned from bona fide mental or cognitive disorders. Specifically, we first developed a Lithuanian version of the IOP-29 and tested its validity on a sample of 50 depressed patients and 50 healthy volunteers instructed to feign depression. Next, we reviewed all previously published IOP-29 studies reporting on depression-related presentations (k = 5), and compared our results against previously reported findings. Statistical analyses showed that the Lithuanian IOP-29 discriminated almost perfectly between genuine and experimentally feigned major depression, with Area Under the Curve (AUC) = .98 (SE = .01) and Cohen's d = 3.31. When compared to previously published IOP-29 literature on this same topic, these findings may be characterized as similar or perhaps slightly more encouraging. Indeed, across all international, empirical studies considered in this article, Cohen's d ranged from 1.80 to 4.30, and AUC ranged from .89 to .99. Taken together, these findings contribute to supporting the strong validity and cross-cultural applicability of the IOP-29. They also provide additional support for its use in forensic evaluations.

An Inventory of Problems-29 (IOP-29) study investigating feigned schizophrenia and random responding in a British community sample.

Compared to other Western countries, malingering research is still relatively scarce in the United Kingdom, partly because only a few brief and easy-to-use symptom validity tests (SVTs) have been validated for use with British test-takers. This online study examined the validity of the Inventory of Problems-29 (IOP-29) in detecting feigned schizophrenia and random responding in 151 British volunteers. Each participant took three IOP-29 test administrations: (a) responding honestly; (b) pretending to suffer from schizophrenia; and (c) responding at random. Additionally, they also responded to a schizotypy measure (O-LIFE) under standard instruction. The IOP-29's feigning scale (FDS) showed excellent validity in discriminating honest responding from feigned schizophrenia (AUC = .99), and its classification accuracy was not significantly affected by the presence of schizotypal traits. Additionally, a recently introduced IOP-29 scale aimed at detecting random responding (RRS) demonstrated very promising results.

Comparability and Validity of the Online and In-Person Administrations of the Inventory of Problems-29.

While the psychometric equivalence of computerized versus paper-and-pencil administration formats has been documented for some tests, so far very few studies have focused on the comparability and validity of test scores obtained via in-person versus remote administrations, and none of them have researched a symptom validity test (SVT). To contribute to fill this gap in the literature, we investigated the scores of the Inventory of Problems-29 (IOP-29) generated by various administration formats. More specifically, Study 1 evaluated the equivalence of scores from nonclinical individuals administered the IOP-29 remotely (n = 146) versus in-person via computer (n = 140) versus in-person via paper-and-pencil format (n = 140). Study 2 reviewed published IOP-29 studies conducted using remote/online versus in-person, paper-and-pencil test administrations to determine if remote testing could adversely influence the validity of IOP-29 test results. Taken together, our findings suggest that the effectiveness of the IOP-29 is preserved when alternating between face-to-face and online/remote formats.

Complexity and Cognitive Engagement in the Rorschach Task: An fMRI Study.

Recently, an eye-tracking study found that Complexity and other R-PAS variables located in the Engagement and Cognitive Processing domain correlated with a proxy marker for cognitive effort and engagement. The goal of the current study was to test the robustness and validity of those eye-tracking findings by inspecting fMRI data. We hypothesized that the greater the level of engagement and cognitive effort put in place by a Rorschach test-taker, the greater the engagement of his/her cortical areas reflecting ongoing top-down attentional processes should be. We re-analyzed archival fMRI data from 26 healthy participants exposed to the Rorschach inkblots with the instruction to think of what they might be. The association of various Engagement and Cognitive Processing R-PAS scores to increased BOLD signals in the Dorsal Attention Network of the brain was examined. As expected, Complexity showed the strongest effect size across all R-PAS variables under investigation (d = 0.43), followed by Synthesis (d = 0.32) and Human Movement (d = 0.21). Noteworthy, the correlation between the effect sizes found in the current fMRI study and those found in the previously published eye-tracking study consists of an impressive r = .80.

A multimethod assessment to study the relationship between rumination and gender differences.

Rumination is described as the propensity of responding to distress by repetitively and passively focusing on one's negative emotions, and failures, and their consequences (Nolen-Hoeksema, 1991, 1998). Therefore, given that rumination is characterized especially by difficulties in managing and controlling negative emotional states, it is considered as the most common (impaired) emotional regulation strategy, and can be defined as an emotional process related to a repetitive, undesired, and past-oriented negatively inclined thought (Compare, Zarbo, Shonin, Van Gordon, & Marconi, 2014; Smith & Alloy, 2009). Recent evidence suggested that because of problems related to monitoring of negative states, rumination may be associated with exaggerated physiological reactivity relative to demands from the environment, and to some difficulties in attentional control abilities. The current study aimed at deepening our understanding of the role that a maladaptive emotional regulation strategy - such as rumination - might play in physiological response changes and in engaging dysfunctional attentional strategies. We used a multimethod assessment including self-reports (i.e., Rumination and Reflection Questionnaire, and Difficulties in Emotion Regulation Scale), physiological measures, (i.e., Heart Rate Variability recording), and attention tasks (i.e., Stroop Task) in order to examine the multiple aspects of rumination across genders. Sixty-eight individuals (30 males and 38 females) were administered DERS -16, RRQ and, soon after them, the Stroop task. Immediately after completing the Stroop task (T1), participants were exposed to a three-phase, baseline-stress-recovery experimental paradigm while their heart rate variability (HRV) was recorded. After completing the experimental paradigm, Stroop stimuli were presented for the second time (T2), in order to examine possible intra-individual differences between the two performances in the Stroop task. Our findings showed that rumination was higher in females than in males, but in men it appeared to be strongly associated with an overall impaired emotional regulation. However, no gender differences in rumination and emotion dysregulation were found when inspecting physiological data. The current study aims to contribute towards a better understanding which emotion regulation strategies and which physiological mechanisms are associated with rumination.
