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.

An Inventory of Problems-29 Sensitivity Study Investigating Feigning of Four Different Symptom Presentations Via Malingering Experimental Paradigm.

The Inventory of Problems-29 (IOP-29) is a newly developed, self-administered test designed to assist practitioners evaluating the credibility of various symptom presentations. In a recent simulation study comparing real patients against experimental feigners, its classification accuracy compared favorably with that of the Structured Inventory of Malingered Symptomatology and generalized better to different types of symptom reports (i.e., mood- or trauma-related vs. psychosis-related). Extending on these findings, this sensitivity study tested whether the IOP-29 would be similarly accurate in detecting feigning of conditions related to depression, mild traumatic brain injury, posttraumatic stress disorder (PTSD), and schizophrenia. Additionally, it also evaluated the susceptibility of the IOP-29 to uncooperative or random-like responding. Examination of 1,200 IOP-29 records from 400 nonclinical Italian volunteers who took the Italian version of the IOP-29 3 times, in 3 different conditions (i.e., standard instructions, feigned disorder, and random-like responding), confirmed that the IOP-29 might be similarly valid across a wide variety of mental health and cognitive complaints. Indeed, using the standard a priori cutoff of the IOP-29 (i.e., ≥ .50), sensitivity estimates ranged from .86 (for feigned PTSD) to .95 (for feigned depression) and did not significantly differ from one symptom presentation to another. These findings were obtained despite the fact that participants were coached to respond in a believable manner. Interestingly, the random-like responding generated extremely variable IOP-29 scores.

An Inventory of Problems-29 Study on Random Responding Using Experimental Feigners, Honest Controls, and Computer-Generated Data.

Self-reports could be affected by 2 primary sources of distortion: content-related (CRD) and content-unrelated (CUD) distortions. CRD and CUD, however, might covary, and similar detection strategies have been used to capture both. Thus, we hypothesized that a scale developed to detect random responding-arguably, one of the most evident examples of CUD-would likely be sensitive to both CUD and, albeit to a lesser extent, CRD. Study 1 (N = 1,901) empirically tested this hypothesis by developing a random responding scale (RRS) for the recently introduced Inventory of Problems-29 (Viglione, Giromini, & Landis, 2017), and by testing it with both experimental feigners and honest controls. Results supported our hypothesis and offered some insight on how to pull apart CRD- from CUD-related variance. Study 2 (N = 700) then evaluated whether our RRS would perform similarly well with data from human participants instructed to respond at random versus computer-generated random data. Interestingly, the sensitivity of our RRS dropped dramatically when considering the data from human participants. Together with the results of additional analyses inspecting the patterns of responses provided by our human random responders, these findings thus posed a major question: Is humans' random responding really random?

A Survey of Challenges Experienced by New Learners Coding the Rorschach.

Learning to code the imagery, communication, and behavior associated with Rorschach responding is challenging. Although there is some survey research on graduate students' impressions of their Rorschach training, research has not identified which coding decisions students find to be the most problematic and time-consuming. We surveyed students to identify what they struggled with most when learning coding and to quantify how difficult it is to learn how to code. Participants (n = 191) from the United States, Brazil, Denmark, Israel, and Italy rated 57 aspects of coding using a 4-point scale that encompassed both the time required to code and the subjective difficulty of doing so. Mean ratings for coding in general indicated that students considered the overall task challenging. Ratings also revealed that students struggled most with Cognitive Special Scores, Determinants, and extrapolating from the tables to code Form Quality for objects that were not specifically listed. The findings offer suggestions about how to improve the guidelines for some of the more difficult variables and where it is most necessary to focus teaching time. Taking these steps might help new students in learning the Rorschach.

An Interrater Reliability Study of Rorschach Performance Assessment System (R-PAS) Raw and Complexity-Adjusted Scores.

Recently, the Rorschach Performance Assessment System (R-PAS; Meyer, Viglione, Mihura, Erard, & Erdberg, 2011 ) was introduced to overcome some possible limitations of the Comprehensive System (CS; Exner, 2003 ) while continuing its efforts to link Rorschach inferences to their evidence base. An important, technical modification to the scoring system is that R-PAS interpretations are based on both standard scores and complexity-adjusted scores. Two previous U.S. studies reported good to excellent interrater reliability (IRR) for the great majority of R-PAS variables; however, IRR of complexity-adjusted scores has never been investigated. Furthermore, no studies have yet investigated R-PAS IRR in Europe. To extend this literature, we examined R-PAS IRR of Page 1 and Page 2 raw and complexity-adjusted scores with 112 Italian Rorschach protocols. We collected a large sample of both clinical and nonclinical Rorschach protocols, each of which was coded separately by 2 independent raters. Results demonstrated a mean intraclass correlation of .78 (SD = .14) for raw scores and.74 (SD = .14) for complexity-adjusted scores. Overall, for both raw and complexity-adjusted values, most of the variables were characterized by good to excellent IRR.

A clinimetric analysis of the Hopkins Symptom Checklist (SCL-90-R) in general population studies (Denmark, Norway, and Italy).

BACKGROUND: Although the Symptom Checklist (SCL-90-R) is one of the most widely used self-reported scales covering several psychopathological states, the scalability of the SCL-90-R has been found to be very problematic. AIMS: We have performed a clinimetric analysis of the SCL-90-R, taking both its factor structure and scalability (i.e. total scale score a sufficient statistic) into account. METHODS: The applicability of the SCL-90-R has been found acceptable in general population studies from Denmark, Norway and Italy. These studies were examined with principal component analysis (PCA) to identify the factor structure. The scalability of the traditional SCL-90-R subscales (i.e. somatization, hostility, and interpersonal sensitivity) as well as the affective subscales (i.e. depression and anxiety and ADHD), were tested by Mokken's item response theory model. RESULTS: Across the three general population studies the traditional scaled SCL-90-R factor including 83 items was identified by PCA. The Mokken analysis accepted the scalability of both the general factor and the clinical SCL-90-R subscales under examination. CONCLUSION: The traditional, scaled, general 83 item SCL-90-R scale is a valid measure of general psychopathology. The SCL-90-R subscales of somatization, hostility, and interpersonal sensitivity as well as the affective subscales of depression, anxiety, and ADHD were all accepted by the Mokken test for scalability, i.e. their total scores are sufficient statistics.

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.

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.

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.

Personality features and vulnerability to stress: a case study on hyperhidrosis.

By using the Rorschach test, self-reports, and psychophysiological measures, we investigated thoroughly the psychological functioning in a hyperhidrotic case. Erica, a young female with hyperhidrosis, was assessed in three times at one-week distance. First, specific tools assessing potential psychological and affective distress, and the Rorschach test were administered. About one week later, Electrodermal Activity was recorded during the exposure to a mild laboratory stress-inducing task. Finally, a magnetic resonance imaging exam was performed in order to exclude medical conditions/neurological alterations for potential physiological anomalies. Erica tends to avoid living in the moment and prefers to experience close relationships in her inner world where she can rehearse the future and imagine different contexts and social situations without risks and embarrassment. She reports high capacities to perform goaldirected behaviors and clarity of emotions only in absence of stressful situations. The study has the merit to be the first to combine Rorschach data with physiological data in order to investigate the psychological functioning in a hyperhidrotic case.

Relationships Between Personality Features and the Rubber Hand Illusion: An Exploratory Study.

The rubber hand illusion paradigm allows investigating human body ownership by inducing an illusion of owning a life-sized fake hand. Despite the wide consensus on the fact that integration of multisensory signals is the main interpretative framework of the rubber hand illusion, increasing amount of data show that additional factors might contribute to the emergence of the illusion and, in turn, explain the strong inter-individual differences of the illusory patterns. Here, we explored whether and how personality features contribute to the emergence of the illusion by administering to healthy participants the rubber hand illusion paradigm along with two well-known personality tests, i.e., the Personality Assessment Inventory (PAI) and the Rorschach test. Results showed that two Rorschach domains (i.e., "Perception and Thinking Problems" and "Self and Other Representation") were positively correlated with the illusory mislocalization of the own left hand toward the fake hand. Further analyses suggested that while the tendency to perceive unconventionally is related to mislocalizing the own hand toward the fake hand, the association of the RHI index and other personality features measured by the Rorschach remain uncertain. However, our findings in general suggest that personality features might have a role in the emergence of the rubber hand illusion. This, in turn, could explain the high inter-individual variability of the illusory effects.

Psychometric properties of the Italian version of the Personality Assessment Inventory (PAI).

The Personality Assessment Inventory (PAI) has been translated into different languages (e.g., Spanish, German, and Greek) and several authors investigated psychometric properties, internal structure, and the convergent validity of translated versions of the PAI. Recently, an Italian version of the test has been published, but its psychometric properties has never been explored. The aims of the present study were: (a) to examine the hypothesized subscale structure of scales that have subscales, (b) to evaluate the internal structure of the 22 PAI full scales, and (c) to report on the convergent validity of the PAI scales with the Millon Clinical Multiaxial Inventory-III (MCMI-III) scales. The sample consisted of 1,538 participants recruited from all over Italy. Our findings provided support to the cross-cultural applicability of the PAI and contributed to enhance confidence in the validity and utility of the PAI. (PsycINFO Database Record

White matter and schizophrenia: A meta-analysis of voxel-based morphometry and diffusion tensor imaging studies.

Voxel-based morphometry (VBM) and diffusion tensor imaging (DTI) are the most implemented methodologies to detect alterations of both gray and white matter (WM). However, the role of WM in mental disorders is still not well defined. We aimed at clarifying the role of WM disruption in schizophrenia and at identifying the most frequently involved brain networks. A systematic literature search was conducted to identify VBM and DTI studies focusing on WM alterations in patients with schizophrenia compared to control subjects. We selected studies reporting the coordinates of WM reductions and we performed the anatomical likelihood estimation (ALE). Moreover, we labeled the WM bundles with an anatomical atlas and compared VBM and DTI ALE-scores of each significant WM tract. A total of 59 studies were eligible for the meta-analysis. WM alterations were reported in 31 and 34 foci with VBM and DTI methods, respectively. The most occurred WM bundles in both VBM and DTI studies and largely involved in schizophrenia were long projection fibers, callosal and commissural fibers, part of motor descending fibers, and fronto-temporal-limbic pathways. The meta-analysis showed a widespread WM disruption in schizophrenia involving specific cerebral circuits instead of well-defined regions.

Embodied simulation and ambiguous stimuli: The role of the mirror neuron system.

According to the "embodied simulation theory," exposure to certain visual stimuli would automatically trigger action simulation in the mind of the observer, thereby originating a "feeling of movement" modulated by the mirror neuron system (MNS). Grounded on this conceptualization, some of us recently suggested that when exposed to the Rorschach inkblots, in order to see a human movement (e.g., "a person running") in those ambiguous stimuli, the observer would need to experience a "feeling of movement" via embodied simulation. The current study used repetitive transcranial magnetic stimulation (rTMS) to further test this hypothesis. Specifically, we investigated whether temporarily interfering with the activity of the left inferior frontal gyrus (LIFG; a putative MNS area) using rTMS would decrease the propensity to see human movement (M) in the Rorschach inkblots. Thirty-six participants were exposed to the Rorschach stimuli twice, i.e., during a baseline (without rTMS) and soon after inhibitory rTMS. As for the rTMS condition, half of the sample was stimulated over the LIFG (experimental group) and the other half over the Vertex (control group). In line with our hypothesis, the application of rTMS over LIFG, but not over Vertex, yielded a statistically significant reduction in the attribution of M to the ambiguous stimuli, with large effect size. These findings may be interpreted as being consistent with the hypothesis that there is a link between the MNS and the "feeling of movement" people may experience, when observing ambiguous stimuli such as the Rorschach cards.
