RESUMO
Therapist expertise is a complex, multifaceted, and continually evolving concept. Defining this construct and its constituent components can yield a substantial contribution to the field of psychotherapy, consequently enhancing the comprehension of the fundamental factors that underlie its effectiveness. Within this framework, the present research aimed at developing and assessing the psychometric properties of the Psychotherapy Expertise Questionnaire (PEQ), a self-report measure to assess therapist expertise. A sample of 260 psychotherapists of various theoretical orientations were involved in this research. They completed a survey that included the PEQ as well as other self-reported measures aimed at evaluating personality traits, self-efficacy, self-esteem, and insight orientation. The analysis provided evidence of a good fit for both a correlational model with eight factors and a higher-order model, where the eight subdimensions were grouped into subjective (performance; cognitive functioning; personal and relational qualities of the therapist; therapist self-assessment) and objective (experience; reputation with clients and colleagues; training and professional updating; deontological ethics and setting rules) factors. The eight dimensions, two higher-order factors, and total score all showed excellent levels of internal consistency. Furthermore, significant associations were found between PEQ scores and insight orientation, general self-efficacy, self-esteem, personality traits, and time exercising clinical practice. To conclude, the Psychotherapy Expertise Questionnaire (PEQ) is a valuable, theoretically guided, and psychometrically robust self-report measure designed to assess therapist expertise and its constitutive dimensions. This measure can have practical applications in guiding tailored training and customised supervision.
RESUMO
This study aimed to explore the relationships among the variables involved in a Comprehensive Model of Addiction (CMA), which posits that the presence and severity of addictive behaviors are related to the configuration of seven psychological variables, namely childhood trauma, insecure attachment, affect dysregulation, dissociation, impulsivity, compulsiveness, and obsessiveness. A vulnerability model was proposed, in which it was suggested that affect dysregulation and complex trauma mediated the association between insecure attachment and dissociation. Furthermore, a maintenance model was elaborated, in which it was hypothesized that dissociation influenced affect dysregulation via impulsivity, compulsiveness, and obsessiveness. A clinical sample of 430 individuals with substance use disorder was involved. All participants received a DSM-5 clinical diagnosis of Substance-Related and Addictive Disorders and were recruited from the Italian National Health System. A parallel mediation emerged, confirming the vulnerability model, with complex trauma and affect dysregulation mediating the relationship between insecure attachment and dissociation. Furthermore, a mixed serial-parallel mediation described the maintenance model, where impulsiveness, compulsiveness, and obsessiveness significantly mediated the relationship between dissociation and affect dysregulation. Our findings offer a better understanding of the variables associated with addictive disorders, thus providing important indications for both treatment and preventive interventions.
RESUMO
This systematic review and meta-analysis aimed to investigate the relationship between dissociation and obsessive-compulsive symptoms (OCS) and disorder (OCD). Specifically, the study aimed to (a) estimate the pooled prevalence of dissociative disorders among individuals with OCD; (b) systematically review the prevalence of OCD among individuals with dissociative disorders; (c) compare the severity of dissociative symptoms between individuals with OCD and non-clinical controls; (d) estimate the association between OCS and dissociative symptoms in the clinical and non-clinical populations. A systematic search was carried out in biomedical databases from inception to January 2022 according to PRISMA guidelines. A total of 41 studies met inclusion criteria (n = 9,438, 34.3% males). The pooled prevalence of dissociative disorders in adult samples with OCD was 8% (95% CI [3, 15], k = 5). Studies on adolescent and adult patients with dissociative disorders found that 17-32% reported comorbid OCD, while a prospective study of patients with early-onset dissociative disorders found no evidence of association with OCD. Individuals affected by OCD reported more dissociative symptoms than non-clinical controls (g = .67, 95% CI [.18, 1.16], k = 9). A moderate correlation between dissociative symptoms and OCS was detected (r = .43, 95% CI [.36, .51], k = 18). Sensitivity analyses showed small/moderate correlations between dissociative experiences and specific types of obsessions and compulsions. Findings suggest that dissociative symptoms are moderately related to OCS in both clinical and non-clinical populations. Interventions aimed to reduce dissociation might improve treatment response of patients suffering from OCD.

BACKGROUND: The clinical relevance of the degree of severity in addiction disorders supports the need to investigate the variables underlying this aspect of the phenomenon. OBJECTIVE: This study aimed to explore the relationships between factors that may influence the severity of addiction disorder, with a particular focus on temperamental disinhibition, emotion dysregulation, interpersonal vulnerability, and their interactions. METHODS: A clinical sample of 502 (77% males and 22% females) was involved. All participants received a DSM-5 clinical diagnosis of "Substance-Related and Addictive Disorders" and were recruited from the Italian National Health System. The collected data were analyzed by implementing a chained mediation model using structural equation modeling. RESULTS: The statistical appropriateness of the hypothesized latent 4- factors model was confirmed. Specifically, temperamental disinhibition (composed of impulsiveness, compulsiveness, and obsessiveness), emotion dysregulation (composed of affect dysregulation, alexithymia, and dissociation), interpersonal vulnerability (composed of traumatic experiences, preoccupied, avoidant and unresolved attachment), and Addictive Disorders Severity (composed by substance use severity, alcohol use severity, gambling severity, and Internet use severity) were the four factors which have been identified. Furthermore, a total chained mediation model emerged, where emotion dysregulation and interpersonal vulnerability mediated the relationship between temperamental disinhibition and Addictive Disorders Severity. CONCLUSIONS: Our findings offer a better understanding of the variables associated with addictive disorder severity, providing important indications for therapeutic interventions.

Objective: The present study aimed at exploring the potential utility of autonomic regulation as a useful marker in the diagnostic differentiation between unipolar and bipolar depression. Method: Respiratory sinus arrhythmia (RSA), low-frequency (LF) of heart rate variability, and systolic blood pressure (SBP) were assessed in patients with bipolar depression (31) and major depressive disorder (MDD=32), and in healthy controls (HCs=32). Since bipolar depressed subjects were maintained on specific medications to manage manic/hypomanic symptoms, we explored whether mood stabilizers (atypical antipsychotics and anticonvulsants or their combinations) could independently affect the physiological parameters. Results: When the autonomic measures were analyzed by a multivariate analysis of variance (MANCOVA), after controlling for BMI, the combination of variables (RSA, LF, SBP) discriminated patients with bipolar depression and MDD from HC (F(6, 178)=3.036, p=0.007, Λ=0.823, partial η2=0.093). In any case, we cannot exclude that mood stabilizers might have affected SBP values in the bipolar group. To deconstruct this multivariate effect, pairwise ANOVAs and discriminant analyses contrasted groups and documented that RSA was the primary variable distinguishing the groups. Discriminant function analyses showed that RSA had a significant discriminating weight between bipolar depressed patients and HC subjects (p<0.0005). By contrast, RSA showed a trend towards the statistical significance in discriminating between bipolar depression and MDD patients (p=0.06). Conclusions: The assessment of RSA and SBP in outpatient settings might be helpful in the differential diagnosis of affective disorders.
RESUMO
BACKGROUND AND HYPOTHESIS: Evidence suggests that childhood maltreatment (ie, childhood abuse and childhood neglect) affects educational attainment and cognition. However, the association between childhood maltreatment and Intelligence Quotient (IQ) seems stronger among controls compared to people with psychosis. We hypothesised that: the association between childhood maltreatment and poor cognition would be stronger among community controls than among people with first-episode of psychosis (FEP); compared to abuse, neglect would show stronger associations with educational attainment and cognition; the association between childhood maltreatment and IQ would be partially accounted for by other risk factors; and the association between childhood maltreatment, educational attainment, and IQ would be stronger among patients with affective psychoses compared to those with nonaffective psychoses. STUDY DESIGN: 829 patients with FEP and 1283 community controls from 16 EU-GEI sites were assessed for child maltreatment, education attainment, and IQ. STUDY RESULTS: In both the FEP and control group, childhood maltreatment was associated with lower educational attainment. The association between childhood maltreatment and lower IQ was robust to adjustment for confounders only among controls. Whereas childhood neglect was consistently associated with lower attainment and IQ in both groups, childhood abuse was associated with IQ only in controls. Among both patients with affective and nonaffective psychoses, negative associations between childhood maltreatment and educational attainment were observed, but the crude association with IQ was only evident in affective psychoses. CONCLUSIONS: Our findings underscore the role of childhood maltreatment in shaping academic outcomes and cognition of people with FEP as well as controls.

Gambling Disorder is a complex and multifaceted phenomenon which requires a careful understanding by analysing both the life experiences and the psychopathological components linked to this type of behaviour. This study aimed to apply a Comprehensive Model of Addiction and to delve deeper the dimensions involved in the vulnerability and maintenance of the disease. Therefore, the effect of alexithymia and traumatic experiences in mediating the relationship between insecure attachment and dissociation, as well as the roles of impulsiveness and compulsiveness in influencing obsessiveness were explored in pathological gamblers. A sample composed of 253 individuals with a mean age of 47.8 years (SD = 12.4) with a diagnosis of Gambling Disorder (82.6% males, 17.4% females) completed the battery of measures. Results showed that alexithymia significantly mediates the relationship between insecure attachment and dissociation, while no significance was found in the effect of complex trauma. Furthermore, a significant impact role of impulsiveness and compulsiveness in determining obsessiveness was found. Therefore, the data suggested that alexithymia may increase the risk of developing a gambling disorder, mediating the association between insecure attachment and dissociation. The model of craving which could have a core role in disease maintenance processes was also confirmed, highlighting a significant influence of impulsiveness and compulsiveness on obsessiveness. Such findings might have relevant implications to increase the effectiveness of both preventive interventions and therapeutic works, favouring positive results for a better mental health of the subjects.

Although personality is a widely discussed topic within the academic field, little is still known about its role in affecting psychopathology, specifically schizophrenia, which can involve psychosis. While the existing literature connects these fields, it is necessary to deepen the knowledge about the relationship between these and the role that personality disorders and traits have on such psychopathology. With the implementation of the AMPD in the DSM-5 and the related assessment of impairment in personality functioning and pathological personality traits, moving from traditional models as the FFM Model of Personality, the present systematic review aims to clarify and summarize the state of the art of the studies regarding this topic. According to the Prisma Statement, literature collection was built based on two databases: PubMed and PsycINFO, and the search focused on recent studies in a period from 2011 to 2020 to check for studies consistent with recent updates. The search process started from 866 articles and ended with 10 selected studies from the two databases, covering years from 2011 to 2020. Studies differ in sample size, measures, aim, and outcome making the present literature review diversified in its content. This review gathers evidence and sheds light on the complexity of these topics and their interconnection. Future studies may be required to clarify the clinical implications of these aspects, aiming at incrementing treatments with a more specific focus on assessment that can provide enhanced preventions.
RESUMO
Several studies have suggested a correlation between heart rate variability (HRV), emotion regulation (ER), psychopathological conditions, and cognitive functions in the past two decades. Specifically, recent data seem to support the hypothesis that low-frequency heart rate variability (LF-HRV), an index of sympathetic cardiac control, correlates with worse executive performances, worse ER, and specific psychopathological dimensions. The present work aims to review the previous findings on these topics and integrate them from two main cornerstones of this perspective: Porges' Polyvagal Theory and Thayer and Lane's Neurovisceral Integration Model, which are necessary to understand these associations better. For this reason, based on these two approaches, we point out that low HRV is associated with emotional dysregulation, worse cognitive performance, and transversal psychopathological conditions. We report studies that underline the importance of considering the heart-brain relation in order to shed light on the necessity to implement psychophysiology into a broader perspective on emotions, mental health, and good cognitive functioning. This integration is beneficial not only as a theoretical ground from which to start for further research studies but as a starting point for new theoretical perspectives useful in clinical practice.
RESUMO
BACKGROUND: DSM-5 provided a dimensional model of personality disorders which may be more clinically informative for the assessment and management of prisoners than a categorical one, as diagnoses of personality disorders alone cannot explain the type of violence. The role of DSM-5 personality facets is however understudied in child molesters, and no study compared these clinical features between individuals who have committed sex crime against children and those who have committed other types of crime. The present study compared DSM-5 personality trait facets between prisoners who had committed sex crime against children, prisoners who had committed property crime (i.e., robbery, fraud) and those who had committed crime against the person (i.e., homicide, assault or violence not implying a sexual element). A further aim was to explore which facets were associated with sex crime against children as compared with the other types of crime, controlling for socio-demographics (age, gender), psychiatric comorbidity (presence of any psychiatric diagnoses) and general psychopathy traits. METHODS: One hundred sixty-seven prisoners participated (91 had committed sex crime against children, 25 property crime, and 51 committed a crime against the person) and completed the Personality Inventory for the DSM-5 and the Psychopathy Checklist-Revised. RESULTS: Prisoners who had committed sex crime against children reported higher Restricted Affectivity traits than those who had committed property crime and crime against the person and higher Irresponsibility traits than those who had committed property crime. The results of a multinomial logistic regression analysis showed that on the one hand being a man, having a higher age, and the presence of a psychiatric comorbidity were more likely to be related to sex crime than property crime, on the other hand higher Irresponsibility personality traits, being a man, and the presence of a psychiatric comorbidity were more likely to be related to sex crime against children than crime against the person. CONCLUSIONS: The Irresponsibility facet might be specific to child molesters and can differentiate this group from offenders who have committed other crime types. This facet might be considered a key target of a tailored assessment and treatment planning during clinical practice with child molesters.

Introduction: Several studies have supported the evidence that attachment styles are a central factor in adolescent gambling problems. On this theoretical basis, the aim of the present study is to analyze a hypothesized mediation model exploring both the direct and indirect effects of insecure attachment on gambling disorder by investigating the role of the developmental perspective, theory of mind (friend) and adaptive response in that relationship. Method: The sample consists of 178 adolescents who underwent the Measures: South Oaks Gambling Screen-Revised for Adolescents and Friends and Family Interview. Result: The mediation analysis was conducted following Hayes' (2018) procedure, using Model 6. The results showed a significant association between insecure attachment and gambling disorder (ß = 0.669; p < 0.001). The findings also highlighted a significant chained mediation model in which insecure attachment negatively influenced the developmental perspective (ß = -0.742; p < 0.001), which affected the theory of mind toward one's own best friend (ß = 0.352; p < 0.001). Conclusions: The results highlighted a significant role of insecure attachment in predicting the symptomatic expression of gambling among adolescents, specifically impacting the development perspective, theory of mind toward one's best friend and adaptive response to stress, which were linked to each other by a sequential influence. Therefore, our results showed that a poor developmental self-vision predicted a dysfunctional theory of mind toward the best friend. This could hinder the formation of positive peer relationships, which are crucial for the development of one's identity.
RESUMO
OBJECTIVE: To investigate the association between prodromal symptoms of schizophrenia, autonomic activity, and personality functioning. METHOD: 10 adolescents underwent semi-structured interviews assessing prodromal symptoms of schizophrenia and personality functioning. Cardiac activity was recorded at baseline, during the clinical interviews, and at recovery to assess concurrent changes in autonomic functioning. RESULTS: During the assessment of prodromal symptoms of schizophrenia, participants increased sympathetic activation compared to the recovery condition, and reduced vagal activation compared to the assessment of interpersonal functioning. CONCLUSIONS: The findings highlight the importance of integrating the autonomic assessment in clinical psychiatric and psychological practice.
RESUMO
BACKGROUND: Many researchers who evaluated psychological distress during the transition to parenthood agree in identifying pregnancy as the most sensitive period for the onset of psychiatric symptomatology for both parents. Furthermore, research highlights a correlation between symptoms experienced by fathers in relation to those experienced by mothers. OBJECTIVE: The aim of this study was to investigate whether dyadic functioning influences the level of psychiatric symptomatology in couples expecting their first child. Participants were 137 couples expecting their first child; they were recruited at the San Filippo Neri and the Santo Spirito hospitals in Rome (ASLROMA1). We used an Actor-Partner Interdependence Model (APIM) to test the interdependence of both partners and the effect of dyadic relationships on psychiatric symptoms in the couple. RESULTS: The overall test of distinguishability yielded a chi square value of 122.167 (23 df; p < .001). The actor-partner interdependence model showed significant paths between couple coping and psychiatric symptomatology. Specifically, we found that the quality of couple coping perceived by the mother negatively predicted maternal psychiatric symptomatology, and the quality of couple coping perceived by the father negatively predicted paternal psychiatric symptomatology. Furthermore, the quality of couple coping perceived by the father negatively predicted maternal psychiatric symptomatology. CONCLUSIONS: The results of this study confirm that dyadic adjustment is an important element for the development of effective interpersonal relationships. These data highlight the importance of promoting psycho-educational and clinical courses and programs for the development of social support with future parents.

OBJECTIVE: Recent research suggests that early signs of schizophrenia can be detected several years before its onset. Evidence suggests that the identification of at-risk individuals before the psychotic onset can significantly improve the course of the disorder. However, instruments employed for the detection of prodromal symptoms are far from being accurate in the prediction of a future transition to psychosis. The aim of the present review is to summarize literature on the early signs of schizophrenia and to identify physiological markers that may aid the identification of the disorder before psychotic transition. METHOD: This critical review includes studies published between 1979 and 2018 that were indexed in major databases with the following keywords: schizophrenia, prodromal phase, basic symptoms, autonomic nervous system, heart rate variability. RESULTS: The examination of the relevant literature showed that, despite recent progress in the identification of at-risk states, the currently employed instruments do not allow an effective prediction of a future psychotic onset. Also, evidence suggests a significant association between alterations in the autonomic nervous system (ANS) functioning and psychotic disorders. However, literature on the association between ANS functioning and at-risk states for psychosis is still scarce. The addition of physiological risk indicators may represent a step forward in the detection of at-risk individuals. CONCLUSIONS: Overall, the present literature review highlights that a future schizophrenic onset cannot be strongly predicted with current available measures. Given the established correlation between schizophrenia and autonomic dysregulation, an investigation of the ANS functioning in individuals who are at increased risk of developing schizophrenia may be particularly useful to improve the quality of the assessment, to identify at an early stage the dysregulated physiological patterns that have been linked with schizophrenia, and therefore to develop tailored interventions. Accordingly, it is crucial that future research investigates the presence of autonomic deficits in individuals at risk for psychosis.
RESUMO
OBJECTIVE: The present study aimed at testing the relationships between measures of psychopathy and measures of the DSM-5 Alternative Model of Personality Disorders (AMPD) domains in a sample of female offenders who were serving their sentences in Italian prisons. METHOD: Thirty-eight Italian adult female inmates were underwent the Italian versions of the Psychopathy Checklist-Revised (PCL-R) and of the Personality Inventory for DSM-5-Informant Report Form (PID-5-IRF). RESULTS: According to MM robust regression analysis results, high scores on the PID-5-IRF Disinhibition domain scale and low scores on the PID-5-IRF Anxiousness trait scale were significant and substantial predictors of the PCL-R total score. CONCLUSIONS: As a whole, our findings support the hypothesis that assessing the DSM-5 AMPD domains (and traits) may be important for tracking psychopathy in female inmates.
RESUMO
This article evaluates the psychometric properties of a new measure for assessing Substance-Related and Addictive Disorders: the Addictive Behavior Questionnaire (ABQ). The ABQ is a self-report measure composed of two sections: the Severity Index (SI) and the Seven Domains Addiction Scale (7DAS). MATERIALS AND METHODS: A total sample of 698 subjects divided into two groups (515 subjects in the clinical sample and 183 subjects in the control sample), participated in this study. We applied Exploratory Factor Analysis (EFA) to examine features of ABQ construct validity, we used Cronbach's alpha coefficient to assess its internal reliability, and explored some aspects of its concurrent validity by examining its associations with other measures assessing addictive behaviors and psychopathology. RESULTS AND CONCLUSIONS: results of EFA indicated that all the scales of the ABQ are unidimensional and showed good internal consistency. The correlations between the sections of the ABQ and the other measures used in the current study were significant and in the expected directions. These results suggest that the ABQ has good psychometric properties and allows researchers and clinicians to gather relevant information regarding behaviors, psychopathology and severity of symptoms, for the best clinical reasoning and for planning tailored treatment for each patient.
RESUMO
Background: Extensive research has demonstrated the positive associations among the exposure to traumatic experiences, the levels of dissociation, and the severity of psychiatric symptoms in adults. However, it has been hypothesized in clinical literature that an excessive activation of the dissociative processes following multiple traumatic experiences may jeopardize the psychological and behavioral functioning of the individuals, fostering higher levels of maladaptive personality functioning. Methods: The study involved 322 adult volunteers from Italy. Participants completed measures on traumatic experiences, dissociation, and maladaptive personality traits. Results: The number of traumatic experiences reported by participants were positively associated with dissociation scores and maladaptive personality scores. Mediation analyses showed that dissociation acted as a partial mediator in the relationship between traumatic experiences and overall maladaptive personality functioning. Regression curve analyses showed that the positive association between maladaptive personality functioning and dissociation was stronger among participants with higher exposure to traumatic experiences. Conclusion: Exposure to multiple traumatic experiences may increase the risk for an excessive activation of the dissociative processes, which in turn may generate severe impairments in multiple domains of personality functioning.
RESUMO
The association between traumatic experiences, alexithymia, and substance abuse is well established. Less is known about the role of traumatic experiences and alexithymia in the onset and maintenance of Internet-related disorders. In the present study, self-report measures on traumatic experiences, alexithymia, and problematic Internet use were administered to 358 high school students (57% females) aged 18-19years old, to test whether alexithymic traits mediated the relationship between traumatic experiences and Internet addiction symptoms, and whether gender moderated the proposed mediation in the sample. While partial mediation occurred in the entire sample, gender directly affected the relationship between the investigated constructs: Internet addiction symptoms were independently related to traumatic experiences among males, and to alexithymic traits among females. Therefore, the results of this study suggest that trauma memories among males, and problems with affect regulation among females, may increase the risk of problematic Internet use during late adolescence. Such findings might have relevant implications to inform any treatment plan for late adolescent students who are overinvolved with online activities, pointing out that tailored approaches to their problems and difficulties are particularly needed in clinical practice.

BACKGROUND: The relationship between substance use disorders and criminal activity is strong, and one that is not easily resolved in the criminal justice system. A better understanding of personality traits among substance misusers who commit offences could support better treatment efforts. AIMS: The aim of this study is to explore associations between the psychopathology of people addicted to substances who have also committed crimes. METHODS: We recruited 263 substance-dependent individuals (80% male, 20% female) from a cohort of people attending regional community services in Italy. They all completed an extensive evaluation of their current mental health and personality traits. Their official criminal records were obtained, and the psychopathology of those who had a criminal record compared with those who did not. RESULTS: The criminal group was more likely to perceive the external world as hostile and to consider others as responsible for their own problems and difficulties; in addition, substance-dependent individuals with criminal records showed more personality traits within the psychopathy range and fewer in the dependent personality range than the substance abusers who had never committed crimes. CONCLUSIONS: These findings allow us to hypothesise that substance abusers who also have criminal convictions may have a specific personality profile. If further research were to confirm this, then it could have important implications for identifying people for particular treatment pathways and developing more effective treatments.
