Research in psychology can have various foci, ranging from the psychological dynamics of single individuals to the generalization across individuals, often termed idiographics and nomothetics, respectively. However, terminological ambiguities have limited communication clarity about idiographics and nomothetics. Importantly, whether studies are sui...

Network approaches to psychopathology have become increasingly common in mental health research, with many theoretical and methodological developments quickly gaining traction. This article illustrates contemporary practices in applying network analytical tools, bridging the gap between network concepts and their empirical applications. We explain...

The COVID-19 pandemic was not only a biological challenge, but it also took a toll on the psychological and social well-being of older adults, especially those in nursing homes. This study aims to uncover the impact of the pandemic on the biopsychosocial well-being of nursing home residents, including the role of COVID-19 positivity and social cont...

Throughout the 21st century, economic inequality is predicted to increase as we face new challenges, from changes in the technological landscape to the growing climate crisis. It is crucial we understand how these changes in inequality may affect how people think and behave. We propose that economic inequality threatens the social fabric of society...

Immersive virtual reality (IVR) technology provides several educational affordances that make it a valuable tool for learning, especially from a constructivist learning perspective. Combined with the increasing availability of Metaverse social platforms, such as ENGAGE and AltSpace VR, where students and teachers can meet and work together, IVR may...

Early maladaptive traits are predictive of later borderline personality pathology (BPP), but little is known about their dynamic interplay over time. This is an important issue to address, however, as significant differences in the ‘clinical weight’ of various traits constituting the early BPP trait phenotype may inform the field on important targe...

Abstract Using five independent non-clinical cross-cultural samples (total N = 3649; overall Mage = 29.31; 31% male and 69% female), this study explored the extent to which Dark Triad traits were indirectly associated with symptoms of psychopathology through mental toughness. Although Machiavellianism and psychopathy have not been studied extensive...

Acceptance and Commitment Therapy (ACT) is purported to work via targeting six interrelated processes summarized as the Psychological Inflexibility/Psychological Flexibility (PI/PF) model. However, the theoretical structure and interconnections of this model have not been sufficiently explored. Lacking are examinations of the interrelations among i...

Cognitive reserve (CR) represents the adaptive response of the cognitive system responsible for preserving normal functioning in the face of brain damage. Experiential factors such as education, occupation, and leisure activities influence the development of CR. Theoretically, such factors build up from childhood and across adulthood. Thus, appropr...

Network Psychometrics emerged in the last years as an approach that allows investigating how different elements of a system interact and how these interactions change across occasions. The present work aims to show the potentialities of the Network Psychometric framework to examine the stability of dynamics of change of psychological processes. Spe...

Objective: Chronic Low Back Pain (CLBP) is the leading cause of disability worldwide, and several factors have been proposed as potential causes or co-factors. We aimed to explore their direct and indirect relations to understand CLBP and identify relevant rehabilitation targets. Methods: 119 CLBP patients and 117 chronic-pain free individuals w...

The HEXACO model divides the space of personality into six main dimensions: Honesty-Humility, Emotionality, eXtraversion, Agreeableness (vs. anger), Conscientiousness, and Openness to Experience. Despite the lexical foundation, no validated adjective-based instruments are available yet. This contribution describes the newly developed HEXACO Adjecti...

Background: The comprehension profile of people with agrammatism is a debated topic. Syntactic complexity and cognitive resources, in particular phonological short-term memory (pSTM), are considered as crucial components by different interpretative accounts. Aim: To investigate the interaction of syntactic complexity and of pSTM in sentence comp...

People in economically advantaged nations tend to evaluate their life as more positive overall and report greater well-being than people in less advantaged nations. But how does positivity manifest in the daily life experiences of individuals around the world? The present study asked 15,244 college students from 62 nations, in 42 languages, to desc...

What are the things that we think matter morally, and how do societal factors influence this? To date, research has explored several individual-level and historical factors that influence the size of our ‘moral circles.' There has, however, been less attention focused on which societal factors play a role. We present the first multi-national explor...

People cooperate every day in ways that range from largescale contributions that mitigate climate change to simple actions such as leaving another individual with choice – known as social mindfulness. It is not yet clear whether and how these complex and more simple forms of cooperation relate. Prior work has found that countries with individuals w...

The network perspective on psychopathology suggests that mental disorders can be regarded as networks of elements that influence each other. In this study, we used network analysis to explore the temporal interactions of anxiety and depression symptoms at the level of day-to-day experiences and find potential explanatory pathways for their comorbid...

There is a growing body of work suggesting that social class stereotypes are amplified when people perceive higher levels of economic inequality—that is, the wealthy are perceived as more competent and assertive and the poor as more incompetent and unassertive. The present study tested this prediction in 32 societies and also examines the role of w...

The Pathological Narcissism Inventory (PNI) is extensively used in recent empirical literature on pathological narcissism. However, most studies using the PNI are community-based, and no studies have used the PNI to investigate narcissistic presentations in personality disordered patients. This study investigates measurement invariance of the PNI i...

Background: Spatial ability (SA) was shown to be important for success in different fields, including STEM. Recent research suggested that SA is a unitary construct, rather than a set of related skills. However, it is not clear how individual differences in different facets of SA emerge, and how they relate to variance in general cognitive ability...

Behavioral effects of non-invasive brain stimulation techniques (NIBS) can dramatically change as a function of different factors (e.g., stimulation intensity, timing of stimulation). In this framework, lately there has been a growing interest toward the importance of considering the inter-individual differences in baseline performance and how they...

Happiness is a valuable experience, and societies want their citizens to be happy. Although this societal commitment seems laudable, overly emphasizing positivity (versus negativity) may create an unattainable emotion norm that ironically compromises individual well-being. In this multi-national study (40 countries; 7443 participants), we investiga...

The first Italian lockdown during COVID-19 pandemic constituted an example of strong situation. Under this context, we investigated associations of HEXACO personality with COVID-19 mitigation behaviors (self-reported hygiene, distancing, going out). We tested unique associations through regularized regressions and out-of-sample prediction after est...

Objective: Personality involves both trait and state components, personal goals serving a crucial regulatory function for the expression of personality states. The present study investigates the dynamic interplay between conscientiousness-related goals, conscientious personality states, and trait conscientiousness. Method: A sample of 244 commun...

Background: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) mainly colonizes nasopharynx. In upper airways acute infections, e.g., the common cold, saline nasal irrigations have a significant efficacy in reducing symptoms. The present study aimed to test the efficacy of nasal lavages in upper airways symptoms of Coronavirus Disease 201...

Objectives The aim of the present study was to develop and validate the CoronaVirus-Disease-2019 (COVID-19) Questionnaire (COVID-Q), a novel symptom questionnaire specific for COVID-19 patients, to provide a comprehensive evaluation which may be helpful for physicians, and evaluate questionnaire's performance in identifying subjects at higher risk...

In recent years, network analysis has been applied to identify and analyse patterns of statistical association in multivariate psychological data. In these approaches, network nodes represent variables in a data set, and edges represent pairwise conditional associations between variables in the data, while conditioning on the remaining variables. T...

A secondary goal of the present study was to evaluate the performance of the COVIDQ...

This study presents the adaptation to the Italian context of the Relationship Profile Test (RPT; Bornstein & Languirand), a self-report measure of Destructive Overdependence (DO), Dysfunctional Detachment (DD), and Healthy Dependency (HD). The RPT was administered to a community sample of 661 nonclinical Italian adults together with the Attachment...

This work investigates the relationship between goals and mitigation behaviors during the COVID-19 pandemic in Italy. Study 1 (pilot) identified goals ascribed to following and violating mitigation-related indications. Study 2 investigated the structure of and link between COVID-related goals and behaviors in a large community sample (N = 995, 301...

Objectives The aim of the present study is to develop and validate the COVID-Q, a novel symptom questionnaire specific for COVID-19 patients, to provide a comprehensive and standard clinical evaluation. A secondary goal of the present study was to evaluate the performance of the COVID-Q in identifying subjects at higher risk of being tested positiv...

Objectives: Patients with coronavirus disease-19 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may present with a wide range of symptoms. In this paper, a detailed characterisation of mild-to-moderate ear, nose nd throat (ENT) symptoms is presented with the aim of recognising the disease early to help reduce fur...

The right hemisphere is involved with the integrative processes necessary to achieve global coherence during reasoning and discourse processing. Specifically, the right temporal lobe has been proven to facilitate the processing of distant associate relationships, such as generating novel ideas. Previous studies showed a specific swing of alpha and...

In 2013, DSM-5 urged for further research on non-suicidal self-injury (NSSI) and defined NSSI disorder (NSSI-D) for the first time separate from borderline personality disorder (BPD). However, research on the comorbidity between NSSI-D and BPD symptoms is still scarce, especially in adolescent populations. The current study selected 347 adolescents...

Objective: Right brain-damaged patients may show omissions and/or additional marks in target cancellation. The latter is classified as perseverative behavior and has been attributed to defective response inhibition or attentional disengagement deficit. This study aimed at (a) verifying that consecutive (immediate) and return (temporally distant) mo...

Abstract What does it mean to be happy? The vast majority of cross-cultural studies on happiness have employed a Western-origin, or “WEIRD” measure of happiness that conceptualizes it as a self-centered (or “independent”), high-arousal emotion. However, research from East�ern cultures, particularly Japan, conceptualizes happiness as including an in...

In pursuit of a more systematic and comprehensive framework for personality assessment, we introduce procedures for assessing personality traits at the lowest level: nuances. We argue that constructing a personality taxonomy from the bottom up addresses some of the limitations of extant top-down assessment frameworks (e.g., the Big Five), including...

We argue that it is useful to distinguish between three key goals of personality science – description, prediction and explanation – and that attaining them often requires different priorities and methodological approaches. We put forward specific recommendations such as publishing findings with minimum a priori aggregation and exploring the limits...

Objective The current exploratory study sought to examine dispositional optimism, or the general expectation for positive outcomes, around the world. Method Dispositional optimism and possible correlates were assessed across 61 countries (N = 15,185; mean age = 21.92; 77% female). Mean‐level differences in optimism were computed along with their r...

Current theories of intelligence maintain that intellectual development is the expression of a strict interplay among different cognitive abilities and the environment. Yet, the environment in which the individual develops has often been reduced to a single measure in empirical research, which thus loses sight of its inherent multifaceted structure...

Individual variation in personality is related to differences in behavioral difficulties and achievement in unselected samples, and in samples selected for high achievement in various domains. This is the first study to explore and compare the connections between self-report measures of personality (Big Five and Dark Triad), behavioral strengths an...

Knowledge of the motivational bases of conscientiousness would be crucial for disentangling competing explanations about the processes underlying this trait. Thereby, building on the results of a previous investigation identifying 21 goal classes connected to conscientiousness (Costantini & Perugini, 2018), we performed three studies aimed at clari...

Current theories of intelligence maintain that intellectual development is the expression of a strict interplay among different cognitive abilities and the environment. This work stems from the need to grasp environmental complexity, by differentiating the contributions of cultural and socioeconomic factors to crystallized and fluid intelligence in...

In this chapter, we introduce the current state of the art of network analysis in personality psychology, and we present networks from both a theoretical and a methodological perspective. We focus on the within-person contemporaneous network which allows exploring the interplay of cognitions, emotions, and behaviors across situations. We illustrate...

The solution to a problem might manifest itself as a burst of unexpected, unpredictable clarity. Such Eureka! events, or Insight moments, are among the most fascinating mysteries of human cognition, whose neurophysiological substrate seems to include a role for oscillatory activity within the α and γ bands in the right parietal and temporal brain r...

Objective: We employed the network methodology to explore the connections between the Dark Triad (DT) traits with Mental Toughness (MT) and the degree to which they account for perceived stress beyond the Big Five (B5). Method: Network analyses were undertaken to explore connections between the DT, MT and perceived stress, independently in two samp...

Power analysis is an important tool to use when planning studies. This contribution aims to remind readers what power analysis is, emphasize why it matters, and articulate when and how it should be used. The focus is on applications of power analysis for experimental designs often encountered in psychology, starting from simple two-group independen...

We argue that clinical information related to an object-relations model of personality pathology can be used by untrained and clinically inexperienced students to rate personality-disordered patients on the Level of Personality Functioning Scale (LPFS). To do so, 73 clinically inexperienced undergraduate students were asked to assess personality fu...

There is ongoing debate about the structure of pathological narcissism. Adopting a network approach, we investigate the core features of pathological narcissism and the nature of traits interconnections in a community sample (N= 944), considering also the effect of personality structure. Results suggest that grandiose fantasies, contingent self-est...

The scientific approach to the study of creative problem‐solving has shifted from using classic insight problems (e.g., the Nine‐dots problem), toward sets of problems that have more robust psychometric properties, such as the Remote Associate Test (RAT). Because it is homogeneous, compact, quickly solvable, and easy to score, the RAT has been used...

The growing literature conceptualizing mental disorders like posttraumatic stress disorder (PTSD) as networks of interacting symptoms faces three key challenges. Prior studies predominantly used (a) small samples with low power for precise estimation, (b) nonclinical samples, and (c) single samples. This renders network structures in clinical data,...

We argue that the series of traits characterizing Borderline Personality Disorder samples do not weigh equally. In this regard, we believe that network approaches employed recently in Personality and Psychopathology research to provide information about the differential relationships among symptoms would be useful to test our claim. To our knowledg...
