Influence of stimuli emotional features and typicality on memory performance: insights from a virtual reality context.

The present study tested the influence of stimuli emotional valence, emotional arousal, and typicality on memory recollection in three groups of participants exposed to the same environment through different modalities: in vivo exposure (i.e., real-life), 3D virtual reality (i.e., VR), and 2D pictures. Context-related free-recall, recognition accuracy, and recognition confidence were analyzed. The results showed that memory performance was best in the real-life modality, and participants in the VR and 2D pictures modalities performed comparably. Interesting effects of stimuli emotional valence and typicality emerged: in the VR and 2D pictures modalities, positive items were better recalled than negative items; typicality was relevant only in the real-life modality, with less common objects within the explored setting (i.e., an office) recalled more often. Furthermore, recognition accuracy and confidence were significantly higher in the real-life modality than in the VR and 2D pictures modalities. Further research is needed to support the creation of VR environments that are sufficiently comparable to real-life contexts in order to obtain higher ecological validity in studies of cognitive performance. In particular, the impact of stimuli typicality and emotional valence in VR contexts should be investigated to gain insight into how these features might improve memory recall in virtual scenarios.

Detecting faking-good response style in personality questionnaires with four choice alternatives.

Deliberate attempts to portray oneself in an unrealistic manner are commonly encountered in the administration of personality questionnaires. The main aim of the present study was to explore whether mouse tracking temporal indicators and machine learning models could improve the detection of subjects implementing a faking-good response style when answering personality inventories with four choice alternatives, with and without time pressure. A total of 120 volunteers were randomly assigned to one of four experimental groups and asked to respond to the Virtuous Responding (VR) validity scale of the PPI-R and the Positive Impression Management (PIM) validity scale of the PAI via a computer mouse. A mixed design was implemented, and predictive models were calculated. The results showed that, on the PIM scale, faking-good participants were significantly slower in responding than honest respondents. Relative to VR items, PIM items are shorter in length and feature no negations. Accordingly, the PIM scale was found to be more sensitive in distinguishing between honest and faking-good respondents, demonstrating high classification accuracy (80-83%).

The COVID-19 lockdown and psychological distress among Italian parents: Influence of parental role, parent personality, and child difficulties.

The Italian lockdown following the spread of COVID-19 exposed residents to a long and unexpected period of managing offspring at home. Throughout this time, most parents continued to work remotely. The present research aimed at assessing multiple sociodemographic and psychological variables for parental well-being during the lockdown. An online survey was administered from 6 to 11 April 2020. Respondents were 917 parents aged 23-67 years with up to six children, aged 3-13 years. The measures employed were: 14 demographic questions, the Big Five Inventory (BFI-10), the Emotional Symptoms and Hyperactivity-Inattention subscales of the Strength and Difficulties Questionnaire (SDQ-P), and the General Health Questionnaire (GHQ-12). Multiple moderated linear regression analyses were performed. Motherhood, higher levels of education, higher neuroticism, lower extroversion, and more child emotional and hyperactivity-inattention symptoms were found to be significant predictors of parent distress. Furthermore, a significant two-way interaction between child emotional problems and parent extroversion was found. Overall, parents showed high rates of psychological distress, signalling severe difficulties during the lockdown. Families with a child suffering from emotional and behavioural difficulties should immediately be detected by social services to activate support interventions to prevent chronic and amplified manifestations of these problems.

Parenting-Related Exhaustion During the Italian COVID-19 Lockdown.

OBJECTIVE: Worldwide, the coronavirus disease 2019 (COVID-19) pandemic has generated significant worry, uncertainty, anxiety, sadness, and loneliness. In Italy, these effects have been particularly pronounced. While research on the COVID-19 outbreak has mainly focused on the clinical features of infected patients and the psychological impact on the general population and health professionals, no investigation has yet assessed the psychological impact of the pandemic on parents. In the present research, we conducted a web-based survey of Italian parents to examine the prevalence of parenting-related exhaustion-and to identify its associated risk and protective factors-4 weeks into the lockdown. METHODS: A total of 1,226 parents provided their consent to participate in the study and completed a demographic questionnaire, information relating to particular COVID-19 experiences, and measures of emotional exhaustion, parental resilience, social connections, and psychological distress during the lockdown. RESULTS: Seventeen percent of our sample experienced significant parenting-related exhaustion, with mothers more severely affected. Multiple regression analyses showed that greater parenting-related exhaustion was predicted by psychological distress, lower parental resilience, motherhood, fewer perceived social connections, and being single, as well as having a child with special needs, having a large number of children, and having younger children. CONCLUSION: The findings add further support to the call for preventive programs to support parents throughout the COVID-19 pandemic. Mental health professionals and social workers should be warned of the effects of lockdown and social distancing on parenting and, consequently, the well-being of children.

Psychopathological characteristics of adjustment disorder among outpatients with and without work related stress.

OBJECTIVES: Study's objective is to assess psychopathological profiles in outpatients with a diagnosis of Adjustment Disorder (AD) who had positive evaluations of work related stress (AD-W) versus those exposed to other stressful life events (AD-O). METHODS: The participants were 70 outpatients with AD-W, compared to 71 outpatients with AD-O, admitted at the Unit of Psychiatry and Occupational Medicine, Sant'Andrea Hospital, Rome. Patients completed the Hamilton Rating Scale for Depression (HRSD), the Hamilton Anxiety Rating Scale (HAM-A), the Minnesota Multiphasic Personality Inventory - 2 (MMPI-2), and the Rorschach test. RESULTS: The emerged data underline that patients with AD-W scored significantly higher than patients with AD-O in the MMPI-2 scales D, Pd, Pa, FAM, and in the Rorschach anxiety scale (Sum Y). CONCLUSIONS: Finally patients with AD-W showed greater levels of psychopathology compared to patients with AD-O. Further studies assessing the harm associated with stress might allow a better understanding of the diagnosis and therapeutic implications of AD.

Shibari: double hanging during consensual sexual asphyxia.

We describe a case of shibari, a double hanging sexual asphyxia practice, which ended fatally for one of the two women involved. We present the autopsy findings and a psychiatric and psychometric evaluation of the surviving participant. The survivor had a borderline personality disorder, had suffered sexual abuse as a child, and had a history of illicit substance consumption, self-harm behavior, and sexual dysregulation. This case study raises doubts regarding the safety measures adopted by participants in masochistic practices and the engagement of people with psychiatric disorders in these extremely dangerous games. Further case studies of living participants in such games are likely to shed light on this practice and facilitate treatment.

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.

Machine learning item selection for short scale construction: A proof-of-concept using the SIMS.

ObjectiveThis proof-of-concept paper provides evidence to support machine learning (ML) as a valid alternative to traditional psychometric techniques in the development of short forms of longer parent psychological tests. ML comprises a variety of feature selection techniques that can be efficiently applied to identify the set of items that best replicates the characteristics of the original test. MethodsIn the present study, we integrated a dataset of 329 participants from published and unpublished datasets used in previous research on the Structured Inventory of Malingered Symptomatology (SIMS) to develop a short version of the scale. The SIMS is a multi-axial self-report questionnaire and a highly efficient psychometric measure of symptom validity, which is frequently applied in forensic settings. Results State-of-the-art ML item selection techniques achieved a 72% reduction in length while capturing 92% of the variance of the original SIMS. The new SIMS short form now consists of 21 items. ConclusionsThe results suggest that the proposed ML-based item selection technique represents a promising alternative to standard psychometric correlation-based methods (i.e. item selection, item response theory), especially when selection techniques (e.g. wrapper) are employed that evaluate global, rather than local, item value.

Parietal resting-state EEG alpha source connectivity is associated with subcortical white matter lesions in HIV-positive people.

OBJECTIVE: Parietal resting-state electroencephalographic (rsEEG) alpha (8-10 Hz) source connectivity is abnormal in HIV-positive persons. Here we tested whether this abnormality may be associated with subcortical white matter vascular lesions in the cerebral hemispheres. METHODS: Clinical, rsEEG, and magnetic resonance imaging (MRI) datasets in 38 HIV-positive persons and clinical and rsEEG datasets in 13 healthy controls were analyzed. Radiologists visually evaluated the subcortical white matter hyperintensities from T2-weighted FLAIR MRIs (i.e., Fazekas scale). In parallel, neurophysiologists estimated the eLORETA rsEEG source lagged linear connectivity from parietal cortical regions of interest. RESULTS: Compared to the HIV participants with no/negligible subcortical white matter hyperintensities, the HIV participants with mild/moderate subcortical white matter hyperintensities showed lower parietal interhemispheric rsEEG alpha lagged linear connectivity. This effect was also observed in HIV-positive persons with unimpaired cognition. This rsEEG marker allowed good discrimination (area under the receiver operating characteristic curve > 0.80) between the HIV-positive individuals with different amounts of subcortical white matter hyperintensities. CONCLUSIONS: The parietal rsEEG alpha source connectivity is associated with subcortical white matter vascular lesions in HIV-positive persons, even without neurocognitive disorders. SIGNIFICANCE: Those MRI-rsEEG markers may be used to screen HIV-positive persons at risk of neurocognitive disorders.

[Maternal attachment patterns and personality in post partum depression]. / Modelli di attaccamento e personalità nella depressione post partum.

AIMS: This study investigates the prevalence of post partum depression (PPD) in a sample of Roman women, and the role of socio-demographic variables, personality structure and maternal attachment patterns, in order to identify primary and secondary prevention strategies. METHODS: Data were collected in two phases. During the third trimester of pregnancy, a sample of 453 women completed a socio-demographic data sheet and the Edinburgh Postnatal Depression Scale (EPDS). Among the patients scoring 12 or more at EPDS, 15 entered the second phase of the study and completed SCID-II and Adult Attachment Interview. PPD diagnosis was confirmed by the SCID-I. The study group was compared with a control group. RESULTS: Among the 453 women who were evaluated, 92 (20.3%) scored ≥12 at EPDS, 39 has been enrolled and 15 entered the study. Presence of depressive symptoms was associated with: complications in pregnancy, previous psychiatric disorders, family and marital conflicts. 66.6% of depressed mothers showed more than one diagnosis on Axis II (particularly avoidant/dependent + borderline or histrionic + dependent). The AAI showed a prevalence of insecure (33.3%) and unresolved/disorganized (46.6%) attachment pattern in the clinical group. DISCUSSION AND CONCLUSIONS: Our results suggest that psychological factors such as personality structure and attachment patterns are not only involved in post natal affective disorders, but have a key role in the onset and development of PPD.

Validation of a new instrument to guide and support insanity evaluations: the defendant's insanity assessment support scale (DIASS).

The insanity defense represents one of the most controversial and debated evaluations performed by forensic psychiatrists and psychologists. Despite the variation among different jurisdictions, in Western countries, the legal standards for insanity often rely on the presence of cognitive and/or volitional impairment of the defendant at the time of the crime. We developed the defendant's insanity assessment support scale (DIASS) based on a wide view of competent decision-making, which reflects core issues relevant to legal insanity in many jurisdictions. To assess the characteristics of the DIASS we asked 40 forensic experts (16% women; years of experience = 20.6 ± 12.9) to evaluate 10 real-life derived forensic cases with the DIASS; cases included defendants' psychiatric symptom severity, evaluated through the 24-itemBrief Psychiatric Rating Scale (BPRS). Exploratory factor analysis by principal axis factoring was conducted, which disclosed a two-factor solution explaining 57.6% of the total variance. The DIASS showed a good internal consistency (Cronbach's alpha = 0.86), and substantial inter-rater reliability (Cohen's kappa = 0.72). The capacities analyzed through the DIASS were mainly affected by mania/excitement and psychotic dimensions in nonresponsible and with substantially diminished responsibility defendants, while by hostility and negative symptoms in responsible defendants. The DIASS proved to be an effective psychometric tool to guide and structure insanity defense evaluations, in order to improve their consistency and reliability.

Obesity and Psychological Factors Associated with Weight Loss after Bariatric Surgery: A Longitudinal Study.

Bariatric surgery is indicated for treatment of severely obese people and can lead to significant weight loss as well as reduction of comorbidities associated with obesity. The present study aims to investigate the relationship between different psychological factors (e.g., tendency to binge eating, impulsivity, alexithymia), adherence to the nutritional plan, and weight loss after bariatric surgery. Forty-five candidates for bariatric surgery accessing a center for the care of obesity were assessed at T0 (pre-surgery) and T1 (6 months post-surgery) through anthropometric and psychometric measures. Simple linear correlations and linear regressions were conducted to evaluate the relationship between the psychological variables, adherence to nutritional plan, and weight loss 6 months after bariatric surgery. Non-planning impulsivity was the principal factor that succeeded in explaining adherence to the diet plan among all the variables considered. Adherence to the nutritional plan and non-planning impulsivity were considered reliable short-term predictors of weight loss after bariatric surgery. This evidence explains the usefulness of promoting research on psychological predictors of outcome in bariatric surgery. Mid- and long-term weight maintenance and quality of life need to be investigated through further follow-up.

High Expressed Emotion (HEE), Assessed Using the Five-Minute Speech Sample (FMSS), as a Predictor of Psychiatric Relapse in Patients with Schizophrenia and Major Depressive Disorder: A Meta-Analysis and Meta-Regression.

Expressed Emotion (EE) describes the tone of a caregiver's response to a patient with a mental disorder, and it is used to predict relapse. The Five-Minute Speech Sample (FMSS) is a 5-min interview with a caregiver that evaluates only two EE dimensions. The present study aimed at evaluating HEE (High Expressed Emotion) as a predictor of relapse in patients with schizophrenia and major depressive disorder. Six studies were selected for the meta-analysis. In total, the studies included 297 subjects. The analyses included a random effects model; a meta-analysis excluding the study with the smallest sample; a cumulative meta-analysis; a meta-regression with random effects, using patient age and duration of illness as moderators; a leave-one-out meta-analysis; and a funnel plot to estimate publication bias. The FMSS emerged as a valid and reliable tool for measuring EE as a predictor of relapse in patients with schizophrenia and major depressive disorder. Patient age and duration of illness had no significant effect on the results. Future meta-analyses should include more studies to reduce publication bias. EE may be a good predictor of relapse when examined through a fast measurement technique such as the FMSS, which may also be useful to analyze the psychopathological structure of caregivers.

How Has COVID-19 Affected Mental Health and Lifestyle Behaviors after 2 Years? The Third Step of a Longitudinal Study of Italian Citizens.

The COVID-19 pandemic and its protective measures had a tremendous effect on the general population's mental health and deeply affected their lifestyle. The present study carried out a longitudinal analysis to evaluate the long-lasting psychological effects of the pandemic and its impact on the general population's day-to-day routine. Three points in time were considered: the initial period of the lockdown (T1; n = 2766; March 2020), the final period of the lockdown (T2; n = 439; May 2020) and two years after the lockdown (T3; n = 268; July 2022). Frequency analyses were carried out to examine which behavioral changes were maintained following the COVID-19 pandemic and lockdown; furthermore, a repeated measures ANOVA test was run to measure differences in depression, stress, and anxiety levels between the three periods considered; lastly, multivariable ordinal logistic regression analyses were carried out to examine which variables were associated with psychological distress more than two years after the lockdown. The results highlighted that depression at T3 was associated with depression at T2 and negative affect, whereas stress at T3 was associated with stress at T2 and detachment. The psychological effects and lifestyle changes are also discussed.

Parietal intrahemispheric source connectivity of resting-state electroencephalographic alpha rhythms is abnormal in Naïve HIV patients.

Previous evidence showed abnormal parietal sources of resting-state electroencephalographic (EEG) delta (< 4 Hz) and alpha (8-12 Hz) rhythms in treatment-Naïve HIV (Naïve HIV) subjects, as cortical neural synchronization markers in quiet wakefulness. Here, we tested the hypothesis that these local abnormalities may be related to functional cortical dysconnectivity as an oscillatory brain network disorder. The present EEG database regarded 128 Naïve HIV and 60 Healthy subjects. The eLORETA freeware estimated lagged linear EEG source connectivity (LLC). The area under receiver operating characteristic (AUROC) curve indexed the accuracy in the classification between Healthy and HIV individuals. Parietal intrahemispheric LLC solutions in alpha sources were abnormally lower in the Naïve HIV than in the control group. Furthermore, those abnormalities were greater in the Naïve HIV subgroup with executive and visuospatial deficits than the Naïve HIV subgroup with normal cognition. AUROC curves of those LLC solutions exhibited moderate/good accuracies (0.75-0.88) in the discrimination between the Naïve HIV individuals with executive and visuospatial deficits vs. Naïve HIV individuals with normal cognition and control individuals. In quiet wakefulness, Naïve HIV subjects showed clinically relevant abnormalities in parietal alpha source connectivity. HIV may alter a parietal "hub" oscillating at the alpha frequency in quiet wakefulness as a brain network disorder.

Bipolar disorder presenting as stalking--a case report.

BACKGROUND: Stalking behaviour may find its roots in an individual's psychological development and culture-related factors that facilitate it. Psychiatric disorders may underlie some stalking cases, but no reports exist of the relationship of actual psychiatric status with the expression of stalking behaviour. CASE REPORT: A 22-year-old adoptive woman perpetrated stalking towards her gynaecologist, who took legal action to protect herself. She was admitted to a general hospital psychiatric department and diagnosed with bipolar disorder-I, manic phase, and personality disorder, not otherwise specified. She was prescribed lithium and valproate combination and followed-up as an outpatient. She underwent cognitive-behavioural therapy incorporating Bowlby's concepts. Stalking behaviour did not reemerge. CONCLUSION: Exacerbations of psychiatric episodes may trigger stalking behaviour. Drug treatment may prevent its clinical expression, but underlying ideation and affect may need long-term psychotherapy focusing on attachment.

Personality and Lockdown: A Study on Italian Undergraduates During the COVID-19 Pandemic.

The current study aimed at increasing our understanding of the psychological impact of the COVID-19 lockdown on undergraduate students, particularly with respect to the association between personality traits; defense mechanisms (DMs); depression, anxiety, and stress symptoms (DASSs); and compliance with the government recommended health measures. A sample of 1,427 Italian undergraduate students were administered the Personality Inventory for the DSM-5-Brief Form; the Defense Style Questionnaire-40; and the Depression, Anxiety and Stress Scale-21. Compliance with the COVID-19 behavioral recommendations was measured through a 10-item survey measure. Results showed that immature DMs and internalizing personality traits (i.e., detachment, negative affect, psychoticism) were risk factors of DASSs. Furthermore, subjects with higher levels of DASSs appeared less compliant with the health measures recommended by the Italian government. Experts may use these results to identify and subsequently support (via the Internet) young subjects at greater risk of mental health problems as a result of the COVID-19 pandemic.

When "Stay at Home" Can Be Dangerous: Data on Domestic Violence in Italy during COVID-19 Lockdown.

The global pandemic caused by a new strain of Coronavirus has brought the Italian government to adopt quarantine, isolation, and lockdown strategies as restrictive measures to reduce the virus spread. Being forced to stay at home could significantly increase the likelihood of episodes of home-based violence and could also be accompanied by a limited possibility of complaints or defense by the victim. The present study aimed to document, through the use of newspaper articles, the characteristics of domestic violence during the lockdown period related to COVID-19 in Italy (from 9 March 2020 up to 18 May 2020) and compare the results with the same period in 2019. The results showed an increase in domestic violence during the lockdown period compared to the same period the year before and highlighted the differences between the dynamics and violent behavior between the two periods examined. The results and limitations of this research are discussed with reference to the literature.

The Relevance of Insomnia in the Diagnosis of Perinatal Depression: Validation of the Italian Version of the Insomnia Symptom Questionnaire.

BACKGROUND: Sleep disorders are common in perinatal women and may underlie or trigger anxiety and depression. We aimed to translate and validate and evaluate the psychometric properties of the Italian version of the Insomnia Symptom Questionnaire (ISQ), in a sample of women during late pregnancy and 6-months postpartum according to the DSM-5 criteria. METHODS: The ISQ was administered to 292 women prenatally along with other measures of sleep quality, depression, and anxiety, to examine its construct and convergent validity. Women were readministered the ISQ six months postdelivery to assess test-retest reliability. Women were divided into DSM-5 No-Insomnia (N = 253) and Insomnia (N = 39) groups. RESULTS: The insomnia group had received more psychopharmacotherapy, had more psychiatric family history, increased rates of medically assisted reproduction, of past perinatal psychiatric disorders, and scored higher on almost all TEMPS-A dimensions, on the EPDS, HCL-32, PSQI, and on ISQ prenatally and postnatally. ISQ scores correlated with all scales, indicating adequate convergent and discriminant validity; furthermore, it showed antenatal-postnatal test-retest reliability, 97.5% diagnostic accuracy, 79.5% sensitivity, 94.9% specificity, 70.5% positive predictive power, and 92.8% negative predictive power. CONCLUSIONS: The ISQ is useful, valid, and reliable for assessing perinatal insomnia in Italian women. The Italian version showed equivalent properties to the original version.

Knowledge and Lifestyle Behaviors Related to COVID-19 Pandemic in People over 65 Years Old from Southern Italy.

BACKGROUND: Control measures adopted during the COVID-19 pandemic had a considerable impact on human daily life and lifestyles. Adherence to the recommended measures is influenced by knowledge and attitudes towards the disease. This cross-sectional study aimed to assess the level of knowledge regarding COVID-19, the related control measures, and lifestyle behaviors adopted during the pandemic in a sample of elderly Italian people. METHODS: A web-based questionnaire investigating socio-demographic characteristics, knowledge of COVID-19, the related preventive measures, and lifestyle changes that occurred during the pandemic, were distributed to ≥65 years old people living in South Italy. RESULTS: A satisfactory level of knowledge about COVID-19 and the related control measures has been found in the enrolled sample. However, a decrease in physical activity, as well as worsening sleeping and dietary habits, were found in roughly 60% of participants. Females were impacted greater by these lifestyle changes. CONCLUSIONS: Participants in this study showed a good level of knowledge regarding COVID-19 and its prevention. Nevertheless, they reported an increase in unhealthy habits that may have important health consequences in the long term and should be addressed by public health interventions targeted at older people.
