The neural correlates of reinforcement sensitivity theory: A systematic review of the frontal asymmetry and spectral power literature.

The original Reinforcement Sensitivity Theory (oRST) proposes two systems of approach (BAS) and avoidance (BIS) motivation to underpin personality and behavior. The revised-RST (rRST) model separates avoidance motivation into passive (BIS; anxiety) and active (FFFS; fear) systems. Prior research has attempted to map RST onto lateralized frontal asymmetry to provide a neurophysiological marker of RST. The main aim is to examine the relationships of the o/rRST scales with trait (baseline) and state (manipulated through experimental paradigms) frontal asymmetry. A systematic review was conducted, resulting in 158 studies designated to neuroimaging research. In total, 54 studies were included in this review using either frontal asymmetry or spectral power. The results were split into three main categories: resting frontal alpha asymmetry (N = 23), emotional induction and state-related frontal alpha asymmetry (N = 20), and spectral analysis (N = 16). Findings indicated that BAS was associated with enhanced left frontal asymmetry at baseline and during state-related paradigms. Findings for BIS were more inconsistent, especially at rest, suggesting that BIS, in particular, may require active engagement with the environment. Only 9 of the 54 papers included used the revised RST model, highlighting the need for more rRST research.

Dispositional Traits, Characteristic Adaptations, and Narrative Identity Reconstructions in Individuals With Depersonalization and Derealization.

INTRODUCTION: Depersonalization and derealization disorder (DPDR) is a debilitating condition. To date, little was known about the role of personality structure and of perceived social support and loneliness in DPDR. METHODS: Three studies investigated, respectively: (i) broadband personality traits (five-factor model), maladaptive trait domains (PID-5), and perceived support and loneliness in individuals with self-reported DPDR (N = 160) versus a general population sample (N = 303), using network modeling; (ii) structure and interconnectivity of personality, perceived support and loneliness, and DPDR traits (frequency/duration) in individuals with self-reported DPDR (N = 160); (iii) characteristic adaptations and narrative identities in individuals with self-reported DPDR (N = 19), using thematic analysis. RESULTS: Study 1 found between-samples differences across several traits, especially psychoticism and negative affect. Differences in networks' global centrality, but not structures or edges, were also found. The graphical model in Study 2 showed a community of dissociative tendencies including DPDR traits and psychoticism. Study 3 highlighted the development of DPDR as a key life transition for those experiencing it, with narratives focusing on feelings of poor agency, isolation, and a disrupted sense of self. CONCLUSIONS: Individual differences in personality characterize DPDR, especially in psychoticism. Implications for theory and research are discussed.

Validation of the Italian version of the 25-item Hikikomori Questionnaire (HQ-25-I).

INTRODUCTION: The present study aimed to adapt the 25-item Hikikomori Questionnaire to the Italian context (HQ-25-I) and to test its psychometric properties in two samples, particularly a sample of residents with psychiatric conditions (n = 117) and a sample of individuals from the community (n = 209). METHODS: We tested the fit of the original three-factor structure (Socialization, Isolation, and Emotional Support) and measurement invariance across the two groups, and the reliability, convergent, and criterion (concurrent) validity of the HQ-25-I. RESULTS: The results showed that the original measurement model fitted the data well and that it was invariant across the two groups. The measure was reliable and positively correlated with some maladaptive personality trait domains (PID-5-BF), Depression (BDI-II), and Hopelessness (BHS) in both groups, with higher scores observed in the clinical sample. However, low correlations were found between the HQ-25-I and the PID-5-BF Detachment and Negative Affectivity. CONCLUSIONS: The results from the study showed that the HQ-25-I is reliable, but further examination of its validity is warranted. Implications for theory and future research are discussed.

Psychometric properties of the Italian version of the Interpersonal Needs Questionnaire-15 (INQ-15-I).

OBJECTIVE: The Interpersonal Needs Questionnaire (INQ-15) is a self-report measure of thwarted belongingness and perceived burdensomeness, two constructs associated with suicidal ideation. The objective of the current study was to translate the INQ-15 from English to Italian (INQ-15-I) and to test its factor structure, reliability, and validity in Italian samples. METHOD: We examined (a) whether the components of the hypothesized two-factor measurement model are invariant across a community sample (N = 510) and a clinical sample (N = 259); (b) the relations between the INQ-15-I factors and measures of depression (Beck Depression Inventory-II), hopelessness (Beck Hopelessness Scale), and suicidal ideation (Beck Scale for Suicide Ideation); (c) the reliability and psychometric properties of the INQ-15-I. RESULTS: Results from multigroup confirmatory factor analyses supported the adequacy of the two-factor model to represent thwarted belongingness and perceived burdensomeness. The model is invariant across community and clinical groups, showing excellent fit. The two INQ-15-I scales measure highly intercorrelated constructs. Both significantly correlate with depression, hopelessness, and suicidal ideation, and correlations are high in the clinical sample. CONCLUSION: The INQ-15-I is a valid and reliable measure of thwarted belongingness and perceived burdensomeness. Implications for research, assessment, and intervention in suicidal ideation are discussed.

Factor structure and psychometric properties of the Italian version of the Gambling Related Cognitions Scale (GRCS-I).

The past decade has witnessed an expanded accessibility and popularity of gambling worldwide, and in Italy the phenomenon significantly increased. Nevertheless, little is known about the role of gambling cognitions among Italian individuals, and few scales assessing problem gambling have been validated. The purpose of the present study was to examine and validate the Gambling Related Cognitions Scale-Italian version (GRCS-I), based on the 23-item Gambling Related Cognitions Scale (GRCS). Two-tailed t tests, ANOVA, MANOVA, Pearson's correlation, and multiple regression analyses were used for continuous variables, while χ(2) tests with Yates's correction for categorical variables. Cronbach's α was utilized to determine the internal consistency, and logistic regression analysis and the receiver operating characteristic curve analysis to determine discriminant validity. Principal axis factoring with Oblimin rotation was applied, and then confirmatory factor analysis was used to cross-validate the factor structures. We extracted a five-factor solution that accounted for 60 % of variance. All 23 items had communalities and factor loadings were satisfactory, and the factor structures were similar to the original version of the measure. The Cronbach's α coefficients were adequate, and concurrent and discriminant validities of the GRCS were also confirmed. GRCS-I presented good psychometric properties and it demonstrated good validity and reliability, providing a valid and suitable tool for the assessment of gambling related cognitions among Italian individuals.

Personality and suicidal ideation in the elderly: factorial invariance and latent means structures across age.

OBJECTIVES: Suicide among the elderly is a dramatic global health problem. Although fatal attempts are frequent in the elderly, research indicated that they rarely present long-term elaboration of suicidal ideation and communicate their intents. Consequently, risk factor detection and assessment are salient. Although evidence on the association between personality and suicidal ideation in young adults is accumulating, little is known about its relevance in the elderly. The purpose of the present study was to analyze the components of a measurement model that are invariant across young adults and older adults and then investigate the relations among dimensions of personality and suicide risk. We postulated a specific relation pattern a priori and tested the hypotheses statistically in order to examine the models for equivalency of the factorial measurement. METHOD: We investigated 316 young adults and 339 older adults, who were administered self-report questionnaires to assess depression, hopelessness, alternative five-factor model of personality, and self-other perception. RESULTS: Multigroup confirmatory factor analyses were conducted, yielding a final model with excellent fit to the data. This model showed a similar pattern of associations between suicidal ideation and personality across both groups. CONCLUSIONS: Although the elderly are exposed to specific life stressors associated with suicidal ideation, our findings suggest that the elderly and young adults may be similar on personality and psychopathology variables predicting suicidal ideation than previously hypothesized. Implications are provided for enhanced assessment and intervention of the elderly high in neuroticism, depression, hopelessness, and with negative self-other perception.

Exploring Older Adults' Subjective Views on Aging Positively: Development and Validation of the Positive Aging Scale.

BACKGROUND AND OBJECTIVES: Historically, aging research has focused primarily on health deterioration and negative aspects associated with aging. This has limited the scope of our understanding of the experience of aging and the relationships between aging and well-being from an integrative biopsychosocial perspective. In the same vein, there is a lack of reliable and valid assessments of aging that capture the positive aspects that characterize and improve the subjective experience of this period of life, particularly one that focuses on psychosocial well-being, including meaningful experiences and activities, group memberships, and general abilities. This study presents the development and validation of the Positive Aging Scale (PAS), a novel self-report assessment. RESEARCH DESIGN AND METHODS: This was an online cross-sectional study conducted on 501 UK residents aged ≥60 years. A number of self-reported items and measures of positive aging, general health, well-being, and cognitive functioning were administered to the sample. We used exploratory and confirmatory factor analyses and assessed the dimensionality, reliability, and concurrent criterion-related validity of the PAS. RESULTS: The results suggested that a unidimensional solution represents the data well, with the positive aging factor adequately loading on 8 items, and the solution showing factorial invariance between young-old and old participants (i.e., ≥75 years). Total PAS scores positively correlate with general health, well-being, and cognitive functioning. DISCUSSION AND IMPLICATIONS: The PAS demonstrated strong psychometric properties and the findings highlight correlations between the PAS and key outcomes of positive aging, including general health. Implications for research and interventions are discussed.

Diversity of Group Memberships Predicts Well-Being: Cross-Sectional and Longitudinal Evidence.

Groups have their health and well-being impacted by satisfying their members' needs and providing resources to help cope with threats. Multiple group memberships serve to accumulate these benefits and also provide resilience to the effects of group loss. However, the additional well-being benefits of belonging to multiple different types of group remain to be determined. In a preregistered cross-sectional survey in Nottingham, England (Study 1, N = 328), we found that group-type diversity predicted well-being and that this effect was fully serially mediated by increased creative self-efficacy, then reduced loneliness. To confirm our hypothesis in a more robust sample we conducted longitudinal analyses on the English Longitudinal Study of Aging (ELSA) dataset (Study 2, N = 5,838) finding that group-type diversity at time one (T1) predicted well-being at T2 (4 years later), even when accounting for wellbeing and loneliness at T1. We discuss the implications for enhancing group-based health interventions.

'You Treated Me Like an Object, I Don't Forgive You!': The Effect of Dehu- manization on Interpersonal Forgiveness from the Victim's Perspective.

Introduction: There is a gap in the literature on the impact of the perceptions of a victim of an offense upon their forgiveness towards the offender, particularly when those perceptions include dehumanization. Objectives: The present cross-sectional exploratory study aimed at examining whether the perceptions of being treated in a dehumanized fashion influences interpersonal forgiveness, avoidance, and revenge intentions of dehumanized victims towards the offender. Method: We recruited 149 individuals from the general population, who took part in an online task, consisting of remembering an offense they had been victim of and of a set of self-reported measures of dehumanization (uniqueness and nature), interpersonal forgiveness, avoidance, and revenge intentions. We used multiple linear regression to test the study's hypotheses. Results: The perceived denial of the victims' human uniqueness was not associated with the dependent variables, whereas the perceived denial of the victims' human nature was significantly and negatively associated with interpersonal forgiveness and positively with avoidance and revenge intentions, after controlling for the effects of a set of known covariates. Conclusions: The results revealed a role for dehumanization (nature) in predicting the victims' interpersonal forgiveness, avoidance, and revenge intentions. Implications for further research are discussed.

Introducción: En la literatura hay una laguna en la comprensión del impacto de las percepciones de la víctima de una ofensa sobre su perdón hacia el ofensor, particularmente cuando estas percepciones incluyen la deshumanización. Objetivos: Este estudio explorativo transversal tuvo como objetivo examinar si las percepciones de ser tratado de manera deshumanizada influyen en las intenciones de perdón interpersonal, evitación y venganza de las víctimas deshumanizadas hacia el agresor. Métodos: Reclutamos a 149 personas de la población general, quienes participaron en una tarea online que consistía en recordar una ofensa de la que habían sido víctima y de un conjunto de cuestionarios sobre la deshumanización (uniqueness y nature), el perdón interpersonal, la evitación, y las intenciones de venganza. Usamos la regresión lineal múltiple para probar las hipótesis del estudio. Resultados: La negación percibida de la singularidad humana de las víctimas no se asoció con las variables dependientes, mientras que la negación percibida de la naturaleza humana de las víctimas se asoció significativa y negativamente con el perdón interpersonal y positivamente con las intenciones de evitación y venganza, después de controlar los efectos de un conjunto de covariables conocidas. Conclusiones: Los resultados revelaron que la deshumanización (nature) tiene un rol en la predicción de las intenciones de perdón interpersonal, evitación y venganza de las víctimas. Se discuten en el artículo las implicaciones para las futuras investigaciones.

COVID-19 preventive behaviours in White British and Black, Asian and Minority Ethnic (BAME) people in the UK.

A model of the effects of ethnicity, political trust, trust in science, perceived ingroup power, COVID-19 risk and fear of COVID-19 upon likelihood of COVID-19 preventive behaviour (CPB) is presented. The structural equation model was a good fit for survey data from 478 White British and Black, Asian and Minority Ethnic (BAME) people. Ethnicity had a direct effect on CPB (BAME reported higher CPB) and an indirect effect on it through political trust, ingroup power, COVID-19 risk and trust in science. Ethnicity was not significantly related to COVID-19 fear. COVID-19 fear and trust in science were positively associated with CPB.

The COVID-19 Own Risk Appraisal Scale (CORAS): Development and validation in two samples from the United Kingdom.

Perceived risk is an important determinant of the adoption of preventive behaviours. In this article, the psychometric properties of the COVID-19 Own Risk Appraisal Scale (CORAS), including its development and validation in two samples in the United Kingdom, are described. The CORAS is a measure of perceived personal risk of contracting the disease, incorporating primarily intuitive with some analytic risk estimates. Exploratory and confirmatory factor analyses were performed on data from 470 participants in the United Kingdom who completed the CORAS, the Fear of COVID-19 Scale and the COVID-19 Preventive Behaviours Index. Results showed that a unidimensional, six-item model fits the data well, with satisfactory fit indices, internal consistency and high item loadings onto the factor. We found no statistically significant differences by age, gender or ethnicity. The CORAS correlated positively with the Fear of COVID-19 Scale and the COVID-19 Preventive Behaviours Index, suggesting good concurrent validity.

Factor structure, reliability and criterion-related validity of the English version of the Problematic Series Watching Scale.

BACKGROUND: Psychological research in the past decade has investigated the psychosocial implications of problematic use of on-demand online video streaming services, particularly series watching. Yet, a psychometric measure of problematic series watching in English is not available. AIMS: The present study aimed to test the factor structure, reliability and criterion-related validity of the English version of the Problematic Series Watching Scale, a six-item self-report assessing problematic series watching, based on the biopsychosocial components model of addiction. METHOD: Participants were recruited from two UK university student samples. Study 1 (n = 333) comprised confirmatory factor analysis, reliability tests and item response theory analyses to test the original unidimensional model and investigate each item's levels of discrimination and information. Study 2 (n = 209) comprised correlation analyses to test the criterion-related validity of the scale. RESULTS: There was a good fit of the theoretical model of the scale to the data (Comparative Fit Index = 0.998, Root Mean Square Error of Approximation = 0.024 [90% CI 0.000-0.093], Standardised Root Mean square Residual = 0.048), satisfactory reliability (ω = 0.79) and item levels of discrimination and information. The scale positively correlated with time spent watching series (rs = 0.26, P < 0.001) and negative affect (rs = 0.43, P < 0.001), and correlated negatively with positive affect (rs = -0.12, P > 0.05), mental well-being (rs = -0.25, P < 0.001) and sleep quality (rs = -0.14, P < 0.05). CONCLUSIONS: Results are discussed in relation to the ongoing debate on binge watching and series watching in the context of positive reinforcement versus problematic behaviour.

Exploring the public's perception of gambling addiction on Twitter during the COVID-19 pandemic: Topic modelling and sentiment analysis.

The present study explored the topics and sentiment associated with gambling addiction during the COVID-19 pandemic, using topic modeling and sentiment analysis on tweets in English posted between 17-24th April 2020. The study was exploratory in nature, with its main objective consisting of inductively identifying topics embedded in user-generated content. We found that a five-topic model was the best in representing the data corpus, including: (i) the public's perception of gambling addiction amid the COVID-19 outbreak, (ii) risks and support available for those who stay at home, (iii) the users' interpretation of gambling addiction, (iv) forms of gambling during the pandemic, and (v) gambling advertising and impact on families. Sentiment analysis showed a prevalence of underlying fear, trust, sadness, and anger, across the corpus. Users viewed the pandemic as a driver of problematic gambling behaviors, possibly exposing unprepared individuals and communities to forms of online gambling, with potential long-term consequences and a significant impact on health systems. Despite the limitations of the study, we hypothesize that enhancing the presence of mental health operators and practitioners treating problem gambling on social media might positively impact public mental health and help prevent health services from being overwhelmed, in times when healthcare resources are limited.

The COVID-19 Preventive Behaviors Index: Development and Validation in Two Samples From the United Kingdom.

Monitoring compliance with, and understanding the factors affecting, COVID-19 preventive behaviors requires a robust index of the level of subjective likelihood that the individual will engage in key COVID-19 preventive behaviors. In this article, the psychometric properties of the COVID-19 Preventive Behaviors Index (CPBI), including its development and validation in two samples in the United Kingdom, are described. Exploratory and confirmatory factor analyses were performed on data from 470 participants in the United Kingdom who provided demographic information and completed the Fear of COVID-19 Scale, the COVID-19 Own Risk Appraisal Scale (CORAS) and the CPBI. Results showed that a unidimensional, 10-item model fits the data well, with satisfactory fit indices, internal consistency and high item loadings onto the factor. The CPBI correlated positively with both fear and perceived risk of COVID-19, suggesting good concurrent validity. The CPBI is a measure of the likelihood of engaging in preventive activity, rather than one of intention or actual action. It is adaptable enough to be used over time as a monitoring instrument by policy makers and a modeling tool by researchers.

The Sexual Risk Behaviors Scale (SRBS): Development & Validation in a University Student Sample in the UK.

University students are at risk of poor sexual health outcomes. The aim of this study was to develop and test the psychometric properties of the Sexual Risk Behaviors Scale (SRBS), a novel short tool for measuring engagement in sexual risk behaviors in university students. We developed a pool of six items based on a review of recent literature and tested its properties in 547 undergraduate students in the United Kingdom. We used Exploratory Factor Analysis and Confirmatory Factor Analysis to explore and determine the factor structure and dimensionality of the SRBS. We used Item Response Theory and specifically the Graded Response Model to investigate items' discrimination, information, and differential functioning, respectively, and logistic regression to test whether higher SRBS scores predicted a diagnosis of any sexually transmitted infections in the past 12 months. Results showed that a unidimensional, five-item model fitted the data well, showing satisfactory fit indices and reliability, with all items providing adequate discrimination and information, and no differential item functioning by gender nor by sexual orientation. SRBS total scores significantly predicted the odds of being diagnosed with sexually transmitted infections in the past 12 months. Implications for public health prevention and intervention are discussed.

Factor Structure and Psychometric Properties of the Italian Version of the Homosexuality Scale of the Trueblood Sexual Attitudes Questionnaire.

The aim of the present study was to translate the Homosexuality scale of the Trueblood Sexual Attitudes Questionnaire into the Italian language and to assess its factor structure and psychometric properties in Italian psychology students. The questionnaire was originally developed and validated in U.S. college students, and later in Turkish social work students, showing high internal consistency. It measures attitudes toward several sexual practices and behaviors, regarding self and others. Particularly, the Homosexuality scale measures attitudes toward different sexual and romantic practices with people of the same sex. A total of 199 Italian psychology students participated to the study, and they were administered the Italian translation of the scale. We applied exploratory factor analysis and confirmatory factor analysis. Results showed that the scale has high internal consistency, and that the original two-factor model accounting for attitudes toward self and others fits the data well. Implications for education and assessment in student populations are discussed.

Executive functions, impulsivity, and inhibitory control in adolescents: A structural equation model.

Background. Adolescence represents a critical period for brain development, addressed by neurodevelopmental models to frontal, subcortical-limbic, and striatal activation, a pattern associated with rise of impulsivity and deficits in inhibitory control. The present study aimed at studying the association between self-report measures of impulsivity and inhibitory control with executive function in adolescents, employing structural equation modeling. Method. Tests were administered to 434 high school students. Acting without thinking was measured through the Barratt Impulsiveness Scale and the Dickman Impulsivity Inventory, reward sensitivity through the Behavioral Activation System, and sensation seeking through the Zuckerman-Kuhlman-Aluja Personali- ty Questionnaire. Inhibitory control was assessed through the Behavioral Inhibition System. The performance at the Wisconsin Card Sorting Task indicated executive function. Three models were specified using Sample Covariance Matrix, and the estimated parameters using Maximum Likelihood. Results. In the final model, impulsivity and inhibitory control predicted executive function, but sensation seeking did not. The fit of the model to data was excellent. Conclusions. The hypothesis that inhibitory control and impulsivity are predictors of executive function was supported. Our results appear informative of the validity of self-report measures to examine the relation between impulsivity traits rather than others to regulatory function of cognition and behavior.

Predictors of success in smoking cessation among Italian adults motivated to quit.

We examined the role of sexual gender, age, working status, education, cigarettes per day, Fagerström test, age of onset, pharmacologic intervention (bupropion or varenicline), 10 sessions of cognitive-behavioral group counseling therapy (GCT) conducted over 6 weeks, and level of attendance of the counseling program as predictors of smoking cessation on 1282 Italian adult smokers. Results of a multi-variate forward stepwise conditional logistic analysis, at the first step, indicate that subjects who attended the program from 4 to 6 sessions and from 1 to 3 sessions, respectively, resulted about 3 times and 24 times more likely to smoke than those attending from 7 to 10 sessions; at the second step, subjects with high Fagerström score were 2 times more likely to smoke than subjects with low/middle Fagerström; at the third step, subjects treated only with GCT were 2 times more likely to smoke than subjects with combined pharmacologic interventions and GCT; at the fourth step, subjects with age of onset less than 17 years were 1.5 times more likely to smoke than subjects with a higher age of onset; eventually, at the fifth step women resulted 1.5 times more likely to smoke than men. In conclusion, we found that a steady attendance of the cognitive behavioral program, as well as the addition of pharmacologic interventions to counseling, remarkably increased the probability of the smoking cessation behavior to be determined. Nevertheless, FTQ was a valid measure in predicting the smoking cessation, and women revealed to be more likely to keep the smoking behavior, as well as subjects who declared an age of onset less than 17 years.

Self/other Perception Mediates Between Personality and Suicidal Ideation in Young Adults

Background and Objectives: Individual differences in vulnerability to suicidal ideation have been recently addressed to internal working models of attachment. However, to date, research has mainly focused on adolescents. Few studies have investigated the role of adult attachment and personality dimensions in suicidal ideation, either examined from a mediational perspective. In this study, we aimed at testing a theoretical model in which Self/other perception mediates between personality and suicidal ideation in young adults. Methods: Dimensions of Attachment (self/other perception), Personality (the Big Five factor model), and Suicidal Ideation (hopelessness and depression) were assessed in a community sample of 319 young adults from Northern Italy. Structural Equation Modeling and mediation analysis were conducted. Controlling for demographic variables (i.e., gender, age, education, and job), we tested three structural models. Results: The final model confirmed our hypothesis that self/other perception mediates between personality (high neuroticism and low extraversion) and suicidal ideation, providing excellent fit to data. Conclusions: In line with the conceptual framework of the Attachment Theory, findings suggest that failure to resolve attachment-related distress is related to the emergence of negative self/other models in adults. Such internal models are likely to attenuate the association between neuroticism and extraversion with depressive symptoms, hopelessness and suicidal ideation (AU)
