Exploring Narcissism in Suicidal Ideation Using the Italian Version of the Guilt and Shame Proneness Scale.

Objective: Several theoretical and clinical observations lead to the hypothesis that pathological narcissism could be associated with suicide ideation due to the difficulty in regulating shame in a functional way. The present study investigated the roles of guilt, shame and rivalry in the relationship between pathological narcissism and suicidal ideation. Methods: A set of self-report questionnaires was completed by a sample of 936 Italian adults. These included the Italian version of the Guilt and Shame Proneness (GASP) scale, the Pathological Narcissism Inventory, the Beck Scale for Suicidal Ideation, and the Narcissism Admiration and Rivalry Questionnaire. Results: A structural equation model that tested the factorial structure of the GASP and its invariance produced satisfactory results. Moreover, shame was a significant factor in the relationship between narcissism grandiosity and suicidal ideation. However, beta regression coefficients were low. Conclusion: These findings suggest that despite clinicians should consider the presence of suicidal ideation in patients with pathological narcissism and their maladaptive regulation of shame, the relationship between these variables is complex and deserve further investigation.

The multifaceted role of emotion regulation in suicidality: Systematic reviews and meta-analytic evidence.

Despite the number of empirical contributions on the topic, scientists have offered contrasting perspectives on the role of adaptive versus maladaptive emotion regulation (ER) strategies in suicidality. Moreover, suicidal attempts and suicidal ideation are likely to be differentially related to single ER strategies. To provide more systematic knowledge that can be used to draw sound conclusions and formulate clinical indications, we carried out a systematic review and meta-analysis that we reported in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards (Moher et al., 2009). From an initial pool of 16,530 articles retrieved from scientific databases (APA PsycInfo, APA PsycArticles, Medline, Scopus, Web of Science, and PubMed) and a search for gray literature, 226 articles were selected to perform 15 meta-analyses. In addition, metaregressions were carried out to test a series of moderators, including the type of suicidality investigated. Among adaptive strategies, results evidenced the role of reappraisal, mindfulness, and several aspects of problem solving. In contrast to our hypothesis, reflective attitude was positively associated with suicidality, calling into question the traditional distinction between adaptive and maladaptive strategies. Regarding maladaptive ER strategies, suppression, avoidance, rumination, brooding, negative problem orientation, and both impulsive and avoidant problem solving proved to be significantly associated with suicidality. Finally, several moderation effects involving age, gender composition, and type of suicidality were observed, supporting the importance of adopting a complex perspective when approaching the topic. Despite the interesting preliminary results, additional research is needed to provide a greater understanding of the interplay between the different ER strategies and suicidality and to develop effective protocols of intervention.

The Difficulties in Emotion Regulation Scale-Dyadic version: A new tool for the evaluation of the dyadic dysregulation in couple relationships.

A new measure for assessing an individual's perception of the dyadic difficulties in emotion regulation with a romantic partner is tested. The Difficulties in Emotion Regulation Scale-Dyadic (DERS-D) was obtained by adapting some items of the previous Difficulties in Emotion Regulation Scale (DERS) to the dyadic context. The scale was administered both to a sample of university students (N = 835) to explore its factorial structure and to a convenience sample (N = 833) together with the DERS, the DERS-Positive, the Emotion Beliefs Questionnaire (EBQ), and the Emotion Regulation Questionnaire (ERQ) to confirm the factorial structure and to explore its construct validity. Results highlight that DERS-D measures two distinct features, namely the lack of dyadic awareness and the lack of dyadic clarity, and that configural invariance across genders was met. DERS-D subscales' internal consistency was high. The correlations between the DERS-D and the other measures demonstrated its construct and criterion validity. The promising nature of these results is discussed in light of the potential clinical and empirical uses of the DERS-D.

Cultural adaptation and validation of the Italian version of the current relationship interview.

Background: The study of romantic relationships is based on attachment theory and the Current Relationship Interview (CRI) is a powerful tool that allows the optimal investigation of attachment representations toward romantic partners. However, evidence in this field is still unsatisfactory and further research is needed. This study aims to examine the associations between the adult attachment to partner, the style of conflict resolution, and dyadic adjustment. Methods: We administrated the Italian version of the CRI, the Dyadic Adjustment Scale (DAS), and the Rahim Organizational Conflict Inventory questionnaire - Section II (ROCI II) - to a sample of 100 heterosexual couples. Results: Individuals with preoccupied attachment reported lower levels of dyadic adjustment and men, but not women, with preoccupied attachment reported lower levels of dyadic cohesion. Levels of dyadic adjustment reported by women/men did not vary according to their attachment types. Levels of dyadic adjustment reported by couples and by women did not vary according to the matching status of attachment types between partners. However, men in romantic relationship characterized by a mismatch between attachment types reported higher levels of consensus compared to their counterparts. Conclusion: The Italian version of the CRI proves an useful tool to investigate processes underlying romantic relationships. The role of current attachment in these processes appears to be highly complex and its investigation might be impacted by methodological issues, calling for additional studies.

Impulsivity traits and suicide related outcomes: A systematic review and meta-analysis using the UPPS model.

BACKGROUND: The affective, cognitive, and behavioral aspects of impulsivity involved in suicide-related outcomes can be investigated through the UPPS model, which conceptualizes these facets in multidimensional terms related to negative and positive urgency, lack of premeditation and perseverance, and sensation seeking. This systematic review and meta-analysis provided a comprehensive understanding of the role of all facets of impulsivity in the development of suicidal ideation and behaviors. METHODS: We conducted a systematic search on six databases (PsycINFO, PsycARTICLES, PubMed, MEDLINE, Scopus, and Web of Science) until May 5,2023. Overall, 49 studies met the criteria for systematic review, of which 37 were included in a meta-analysis of data from 17.898 individuals. Additional moderation analyses included age, gender, sample status, country of study conduct, assessment instruments, type of suicide-related outcome, study quality, and research design. RESULTS: We found significant relationships between aspects of impulsivity and suicide-related outcomes. Specially, affective facets related to impulsivity showed a stronger association with suicidal ideations and attempts than cognitive and behavioral dimensions, recommending the main involvement of emotional aspects-positive and negative-in suicide-related dimensions. LIMITATIONS: The limited number of studies may have negatively impacted the power of moderation analyses. In addition, for most dimensions of impulsivity, the limited number of longitudinal studies did not allow to test the moderating role of research design. CONCLUSIONS: This study supports the role of impulsivity in suicidal ideation and behavior, identifying the affective component of impulsivity as the most involved, providing a significant contribution from a clinical and diagnostic point of view.

Investigating the Path From Non-Suicidal Self-Injury to Suicidal Ideation: The Moderating Role of Emotion Dysregulation.

OBJECTIVE: Non suicidal self-injury (NSSI) and suicidal ideation are reliable antecedent events of suicide risk. To date, it remains unclear what implicit emotion regulation mechanisms are involved in these aspects and what is their role in the link between NSSI and suicidal ideation. The purpose of our study is to present evidence on the association between NSSI, suicidal ideation, and dysregulation of positive and negative emotions with the aim of providing empirical data useful in explaining the role of emotional dysregulation in the development of self-injurious and suicidal thoughts and behaviors, to contribute to the development of accurate and focused prevention and treatment directions. METHODS: The study was conducted on 1,202 individuals from a community sample (34.3% male; mean age of 30.48 [standard deviation= 13.32] years). Demographic information, including medical history, was collected in a form. We conducted analyses assessing suicidal ideation using the Beck Suicide Ideation Scale, NSSI using the Deliberate Self-Harm Inventory, and difficulties in negative emotion regulation and positive emotion regulation using the Difficulties in Emotion Regulation Scale and the Difficulties in Emotion Regulation Scale-Positive. RESULTS: Checking for age and gender, we found that both suicidal ideation and dysregulation of only negative emotions can predict NSSI. In addition, the results demonstrated that emotion dysregulation partially mediates the relationship between suicidal ideation and NSSI. CONCLUSION: NSSI is traditionally distinguished from suicidal intent, even so it might be interesting to explore the intentional aspect in patients who present with persistent and severe self-injurious behaviors.

The Relation of Anxiety and Avoidance Dimensions of Attachment to Intimate Partner Violence: A Meta-Analysis About Victims.

Objective: Attachment theory is a useful framework for understanding the phenomenon of intimate partner violence (IPV) victimisation. Many studies have examined the relationship between attachment and IPV victimisation. The need to examine the nature of this relationship through a meta-analytic approach arises from an awareness of the amount of contrasting data surrounding the topic. Method: Searching five databases (PsycINFO, PsycARTICLES, MEDLINE, Scopus, Web of Science and PubMed) and screening 4343 records, resulted in 34 studies comprising 1271 individuals who met the inclusion criteria for this meta-analysis. Results: Results about attachment anxiety showed significant and moderate effect sizes (ranging from .18 for generic violence to .25 for sexual violence). Results about attachment avoidance also showed significant and moderate effect sizes (ranging from .18 for physical violence to .30 for generic violence). Conclusions: The meta-analysis findings highlight that the relationship between the dimensions of anxiety and the avoidance of attachment are significantly related to all forms of IPV victimisation, with moderate and moderate-to-strong effect sizes, respectively. These results are significant in that they confirm the importance of the relationship between attachment and IPV victimisation, suggesting promising new directions in which this field can further develop.

Post-Traumatic Stress Disorder and Alcohol Use Disorder During the COVID-19 Outbreak: Do Dissociation and Emotional Metacognitive Beliefs Mediate the Role of Emotion Dysregulation?

OBJECTIVE: Despite the well-documented relationship between emotion dysregulation and both post-traumatic stress disorder (PTSD) and alcohol use disorder symptoms, no studies investigated this issue in the context of the outbreak. Moreover, additional research investigating the role of mediators intervening in these pathways is required. Dissociation and emotional beliefs are two factors that may explain such relationships. However, a poor number of studies empirically tested their role. METHODS: A cross-sectional study on a sample of 719 community participants (32.5% males; Mage=34.36, standard deviation=14.38 years) was conducted. Participants fulfilled a battery of self-report questionnaires measuring levels of PTSD outbreak-related symptoms, alcohol use disorder, emotion dysregulation, emotional beliefs, and dissociation. RESULTS: Partial r-Pearson correlations showed that PTSD symptoms' level was positively and significantly related to all variables investigated in the study whereas alcohol use disorder level was positively and significantly associated with emotion dysregulation and only some dimension of emotional beliefs and dissociation. Results drawn from a structural equation model highlight the mediating role of both emotional belief and dissociation in the relationship linking emotion dysregulation and alcohol use disorder whereas only dissociation, but not emotional beliefs, mediated the link between emotion dysregulation and PTSD symptoms. CONCLUSION: Most of the hypotheses have been supported stressing the relevance of both dissociation and emotional beliefs in PTSD and alcohol use disorder symptoms. These two variables appear important framework from which deepen the impact of emotion dysregulation in psychopathology.

Alexithymia in Facebook Addiction: Above and Beyond the Role of Pathological Narcissism.

BACKGROUND: Personality dysfunctions and deficits in the capacity to cope with negative emotional states have been related to internet addictions. However, in relation to Facebook addiction, this issue remains poorly investigated. Specifically, few studies explored the role played by grandiose and vulnerable narcissism in Facebook addiction. Furthermore, the relationship between alexithymia and pathological narcissism has not yet been explored in relation to problematic Facebook use. The main objective of this study was to examine the association among Facebook addiction, pathological narcissism and alexithymia. METHOD: A cross sectional study was designed to this aim. A sample of adult participants (N=270; Mage=41.05; SD=14.05) was administered the Bergen Facebook Addiction Scale (BFAS), The Pathological Narcissism Inventory (PNI) and the Toronto Alexithymia Scale (TAS-20). RESULTS: Results showed that pathological narcissism, and especially grandiose narcissism, appears to be an important factor associated to problematic Facebook usage among adults. Moreover, difficulties in the capacity to identify their own emotional states may be a risk factor for such condition. CONCLUSIONS: In conclusion, these results are in line with other data found in the field of behavioral addictions and add further reflection for planning more specific clinical intervention programs for individuals addicted to Facebook with narcissistic traits. These may benefit from a greater focus on the impairments in self-monitoring capacities such as emotional awareness. Personality psychopathologies should be targeted by clinical interventions, but also broader functional impairments (as such as alexithymia) should be addressed as more strategic therapeutic objectives in the field of Facebook Addiction.

The Relation of Anxiety and Avoidance Dimensions of Attachment to Intimate Partner Violence: A Meta-Analysis About Perpetrators.

OBJECTIVE: The attachment theory is a useful framework for interpreting the phenomenon of intimate partner violence (IPV) perpetration. Although several studies have examined the relationship between attachment and IPV perpetration, a meta-analysis of these results has yet to be conducted. METHOD: After a search on five databases (PsycINFO, PsycARTICLES, MEDLINE, Scopus, Web of Science, and PubMed) and a screening of 3,852 records recruited, 52 studies comprising 13,653 individuals met the inclusion criteria for this meta-analysis. RESULTS: Results showed a significant effect size for both the anxiety and avoidance dimensions of attachment. However, while the effect sizes for anxiety were consistent (r = .19-.35) for all types of violence considered, the effect size for avoidance was not significant for generic violence (r = .07), low for physical (r = .12) and psychological violence (r = .14), and medium for sexual violence (r = .20). Only a few of the examined moderators were significant. CONCLUSIONS: The findings highlight some differences in the roles of the two attachment dimensions in IPV. The results underscore the need for additional research to explore the role of other potential moderating and mediating variables in the relationship between attachment and IPV perpetration in order to better support the development of prevention and treatment interventions.

Treating intimate partner violence with metacognitive interpersonal therapy: The case of Aaron.

Intimate partner violence (IPV) is responsible for loss of lives and significant psychological, financial, and social costs. Research into therapeutic effectiveness show inconsistent results irrespective of therapeutic orientation. The capacity to understand one's own mental states as subjective and distinct from others is an important factor in the regulation of mental states and physiological arousal associated with the perpetration of IPV. Metacognitive Interpersonal Therapy (MIT) offers an innovative approach in working with male perpetrators of IPV. The current paper outlines 14 sessions of MIT with a 45-year-old male perpetrator. A core aspect was helping the client resolve how his view of self and others were subjective experiences that were distinct from relational objectivity. The emergence of healthy self-narratives was fostered through experiential processes, involving guided imagery, rescripting and body focused interventions. Qualitative outcomes are summarized and implications for the use of MIT in treatment of perpetrators of IPV is discussed.

Heart rate variability and interoceptive accuracy predict impaired decision-making in Gambling Disorder.

BACKGROUND AND AIMS: Gambling Disorder (GD) entails maladaptive patterns of decision-making. Neurophysiological research points out the effect of parasympathetic arousal, including phasic changes in heart rate variability (HRV), and interoceptive accuracy (IA, i.e., the ability to track changes in bodily signals), on decision-making. Nevertheless, scarce evidence is available on their role in GD. This is the first study exploring the impact in GD of respiratory sinus arrhythmia (RSA), an index of HRV, and IA on decision-making, as measured by the Iowa Gambling Task (IGT). METHODS: Twenty-two patients experiencing problems with slot-machines or video lottery terminals gambling and 22 gender- and age-matched healthy controls (HC) were recruited. A resting ECG was performed before and after the completion of the IGT. IA was assessed throughout the heartbeat detection task. We conducted a MANCOVA to detect the presence of significant differences between groups in RSA reactivity and IA. A linear regression model was adopted to test the effect of factors of interest on IGT scores. RESULTS: Patients with GD displayed significantly decreased RSA reactivity (P = 0.002) and IA (P = 0.024) compared to HCs, even after controlling for affective symptoms, age, smoking status, and BMI. According to the linear regression model, cardiac vagal reactivity and IA significantly predict decision-making impairments on the IGT (P = 0.008; P = 0.019). DISCUSSION AND CONCLUSIONS: Although the exact pathways linking HRV and IA to impaired decision-making in GD remain to be identified, a broader exploration relying upon an embodiment-informed framework may contribute to shed further light on the clinical phenomenology of the disorder.

Emotion dysregulation acts in the relationship between vulnerable narcissism and suicidal ideation.

Suicide behaviors are peculiar aspects of several cluster B disorders, including Narcissistic Personality Disorder. To date, it is still unclear which facet of narcissism is more related to the desire to die and which other factors are involved in this relationship. This study aims to offer preliminary empirical evidences concerning the relationship between narcissism, emotion dysregulation and suicide ideation. We administered the Pathological Narcissism Inventory (PNI), Difficulties in Emotion Regulation Scale (DERS), PID-5-BF (Personality Inventory for DSM-5-Short Form) and Beck Scale for Suicide ideation (BSI) to a sample of individuals with suicide ideation (n = 70) and a sample of community participants (n = 154). Controlling for age, gender and Negative Affectivity, we found that BSI scores correlated significantly with the vulnerable dimension of narcissism, but not with the grandiose one, and with all DERS dimension, apart from Awareness. Nevertheless, emotion dysregulation moderates the relationship between vulnerable narcissism and suicide ideation. Suicide ideation seems to be deeply connected with the vulnerable dimension of pathological narcissism and the relationship between the constructs is totally mediated by emotion dysregulation. Future directions and clinical implications are discussed.

A Fear of COVID-19 and PTSD Symptoms in Pathological Personality: The Mediating Effect of Dissociation and Emotion Dysregulation.

Background: The 2019 coronavirus disease (COVID-19) outbreak is currently putting a strain on the mental health resilience of the world's population. Specifically, it is likely to elicit an intense response to fear and to act as a risk factor for the onset of posttraumatic stress disorder (PTSD). Some individuals may be more at risk than others, with pathological personality variables being a potential candidate as a central vulnerability factor. In addition, the pathways that lead the pathological personality to PTSD and intense fear responses to COVID-19 are likely to be explained by poor emotion regulation capacities, as well as by dissociative mechanisms. Aims: This study aimed to shed light on vulnerability factors that may account for the onset of PTSD and intense responses of fear in response to COVID-19 outbreak and to test the mediating role of emotion dysregulation and dissociation proneness in these pathways. Methods: We used a longitudinal design of research administered to a sample of community individuals (N = 308; meanage = 35.31, SD = 13.91; 22.7% were male). Moreover, we used self-report questionnaires to measure pathological personality, emotion regulation capacities, dissociative proneness at the beginning of the lockdown, and PTSD symptoms and fear of COVID-19 at the end of the Italian lockdown (from March 9 to May 18, 2020). Structural equation modeling was used to test the hypotheses. Results: We found that pathological personality levels longitudinally predicted PTSD and fear of COVID-19 levels. Moreover, the associations between emotion dysregulation and dissociation were shown to significantly and totally mediate the relationship between pathological personality and PTSD, whereas no significant mediation effects were observed in relation to fear of COVID-19. Conclusions: Individuals with pathological personality traits may be more vulnerable to the onset of negative psychological consequences related to COVID-19 outbreak, such as PTSD symptomatology and fear levels. Emotion regulation capacities appear to be relevant targets of interventions for PTSD symptomatology. Future research should explore the mediating variables linking pathological personality to intense fear responses to COVID-19.

Gambling disorder and dissociative features: A systematic review and meta-analysis.

OBJECTIVE: Multilevel consequences related to gambling disorder (GD) are glaring enough to make gambling a worldwide public health issue. Dissociation has been pointed out in clinical, empirical, and theoretical contributions as a key variable accounting for the development and maintenance of GD. However, we still lack a systematization of available empirical data that may facilitate further accurate conclusions. METHOD: A systematic review and meta-analysis were performed with the goal to answer to open questions. We followed the PRISMA guidelines conducting a systematic search of 5 scientific databases (PsycINFO, PsycARTICLES, MEDLINE, Scopus, Web of Science, and PubMed) including grey literature. RESULTS: A total of 843 records were screened, and 20 studies were included in the qualitative and quantitative analyses. A systematic review of selected studies outlines the high heterogeneity in the operationalization of the dissociation construct as well as the absence of studies examining the role played by the specific dimensions of the pathological dissociative feature in GD. A significant, positive, and moderate effect size (r = .37) was found linking GD to dissociation. Moreover, this effect appears to not be moderated by the quality of studies, age, and gender of participants nor measures used to evaluate dissociation. CONCLUSIONS: Despite empirical evidences supporting the theoretical assertions toward the relationship between GD and dissociation, few studies have reached an articulated understanding of this topic, mostly failing to identify specific dissociative features involved in GD. Furthermore, the existence of the current gap in the literature are discussed to delineate future lines of research. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Psychopathy and Aggression: The Role of Emotion Dysregulation.

The importance of psychopathy in the forensic and criminal justice domains is largely due to its robust associations with aggression and violent behavior. Hence, investigators have increasingly been interested in elucidating potential mechanisms linking psychopathy and aggression. Recent research highlighted previously overlooked associations between psychopathy and difficulties in emotion regulation, the process responsible for monitoring, evaluating, and managing one's emotional experience, as well as for guiding behavior under intense emotional arousal. Yet, it remains unclear whether emotion dysregulation may be helpful to explain well-documented associations between psychopathy and aggression. The present study examined whether emotion dysregulation mediated associations (i.e., explained a significant portion of the shared variance) between psychopathy and aggression across community (N = 521) and offender (N = 268) samples. Participants completed self-report measures of psychopathy, emotion dysregulation, trait aggressiveness (i.e., anger, hostility, physical and verbal aggression), as well as reactive and proactive aggression. Across both samples, psychopathy had significant indirect effect on all indices of aggression through emotion dysregulation, with the exception of verbal aggression. These findings support the relevance of emotion regulation for the construct of psychopathy and its maladaptive correlates and highlight the potential relevance of focusing on emotion regulation as a possible target for interventions aimed at reducing aggression among individuals with psychopathic traits.

Metacognition in gambling disorder: A systematic review and meta-analysis.

INTRODUCTION: In recent literature, abnormalities in the metacognitive domain have been pointed out as psychological variables that may account for a wide range of psychopathologies, including gambling disorder (GD). Considering the growing but scattered nature of the research concerning the relationship between metacognition and GD, a systematic review and meta-analysis of the existing results are required. METHODS: We performed a systematic search through five scientific databases for research published till December 10, 2019, following PRISMA guidelines. We also searched grey literature. After removing the redundancy, 16.855 records were screened. RESULTS: Unanimously, authors selected 10 articles based on the inclusion criteria. Four of the selected studies evaluated metacognitive abilities towards cognitive performances, mostly considering metacognitive deficits about decision-making, while metacognitive beliefs were assessed by six of the selected articles. Only one study examined metacognitive functioning regarding GD. The meta-analytic procedure was performed on 10 identified studies based on the criteria adopted, which comprised 1.655 individuals. Results showed that the average effect size linking metacognitive dysfunctions and GD was significant and moderated by the instrument used to measure metacognition. CONCLUSIONS: The examined line of research is highly heterogeneous owing to the type of operationalization adopted for metacognition. The systematic review also showed a grey area, evidencing the lack of research on metacognitive functions. Results demonstrated by this meta-analysis call for future studies examining the role of metacognitive deficits in GD in order to delineate useful clinical indications.

An investigation of spitefulness in violent offenders: Associations with the dark triad and emotion dysregulation.

BACKGROUND: Spitefulness is the inclination to inflict harm to someone else even at one's own expenses. The development of a self-report measure (the Spitefulness Scale [SS]) has fostered the investigation of the relationships between spitefulness and aggression-related variables. OBJECTIVE: The present study aims to investigate the construct of spitefulness in violent offenders. Through a translation/back-translation procedure, the SS was translated into Italian, and its psychometric properties were examined. METHOD: A sample of 249 male violent offenders and 172 male community participants filled out the SS, the Self-Report Psychopathy Scale-IV, the Difficulties in Emotion Regulation Scale and the Dirty Dozen Scale. RESULTS: Confirmatory factor analysis results supported the unidimensional factor structure of the SS. Further results indicated that the scale had good internal consistency and met criteria for configural invariance, partial weak invariance and partial strong invariance across samples. Correlational analyses evidenced positive and significant associations between the SS scores and measures of the dark triad and emotion dysregulation. The offender sample scored significantly higher than the community sample on the SS. CONCLUSION: Results support the internal structure and construct validity of the SS, suggesting its potential utility for the study of the construct of spitefulness in violent offenders. © 2020 John Wiley & Sons, Ltd.

Psychopathy and emotion dysregulation: More than meets the eye.

Emotional dysfunctions have long been associated with psychopathy. Yet, the extent to which these dysfunctions include problems in emotion regulation (ER) has only recently become clearer. In this study, we first reviewed theoretical and empirical literature on psychopathy and ER, and then examined associations between ER and psychopathy in four diverse samples from two countries (MTurk, college, community, and offender samples from the United States and Italy; total N = 1940). We employed Structural Equation Modeling (SEM) to examine latent associations between ER and measures of psychopathy and the dark triad, respectively. Results revealed a consistent pattern of moderate associations between psychopathy and poorer ER. These patterns were replicated across samples and psychopathy assessment, and held when including Machiavellianism and narcissism in the models. Replicating and extending recent studies, these findings provide incremental evidence that the emotional dysfunctions associated with psychopathy include problems in ER. Thus, we contend that prevention efforts in the general community, as well as clinical risk assessment and treatment planning in clinical (forensic) populations should include an emphasis on ER, as it may represent an important factor explaining some of the maladaptive correlates of psychopathic personality.

Improving the psychometric properties of the dissociative experiences scale (DES-II): a Rasch validation study.

BACKGROUND: The Dissociative Experiences Scale-II (DES-II) is a self-report questionnaire that measures dissociative experiences such as derealization, depersonalization, absorption and amnesia. The DES-II has been prevalently used as a screening tool in patients suffering from psychotic disorders or schizophrenia. However, dissociative experiences can also be part of normal psychological life. Despite its popularity, the most problematic aspect of the DES-II is the inconsistency in its factor structure, which is probably due to the tendency to treat ordinal responses as responses on an interval scale, as it is assumed in the Classical Test Theory approach. In order to address issues related to the inconsistency of previous results, the aim of the present study was to collect new psychometric evidence to improve the properties of the DES-II using Rasch analysis, i.e. analyzing the functioning of the response scale. METHODS: Data were obtained on a sample composed by 320 Italian participants (122 inmates and 198 community-dwelling individuals) and were analyzed with the Rasch model. This model allows the estimation of participants' level of dissociation, the degree of misfit of each item, the reliability of each item, and their measurement invariance. Moreover, Rasch estimation allows to determine the best response scale, in terms of response modalities number and their discriminant power. RESULTS: Three items of the scale had strong misfit. After their deletion, the resulting scale was composed by 25 items, which had low levels of misfit and high reliability, and showed measurement invariance. Participants tended to select more often lower categories of the response scale. CONCLUSIONS: Results provided new knowledge on the DES-II structure and its psychometric properties, contributing to the understanding and measurement of the dissociation construct.
