RESUMO

BACKGROUND: Dysmorphic concern (DC) is a symptom affecting both clinical and non-clinical populations, with a severe impact on individuals' physical and psychological well-being. While Childhood Trauma (CT) has been identified as a risk factor for DC, there is a lack of research on a specific form of CT, that is, parental overcontrol. Therefore, the current study aimed to investigate the association between DC and parental overcontrol in a community sample of adults, controlling for other forms of CT and potential confounding variables. METHOD: 714 adults (508 females; mean age: 30.29 ± 11.67 years; age range: 18-77) participated in an online survey including the Body Image Concern Inventory (BICI), the Overcontrol subscale of the Measure Of Parental Style, and the Childhood Trauma Questionnaire - Short Form (CTQ-SF). RESULTS: Parental overcontrol was independently associated with DC symptoms (ß = 0.111; p = .005; CI = [0.119;0.666]), even after controlling for other forms of CT and sociodemographic and clinical confounding variables. LIMITATIONS: The cross-sectional design of the study, the unbalanced sex ratio, the retrospective self-reported data about parental overcontrol and CT should be considered. CONCLUSIONS: This finding suggests that parental overcontrol may play a role in the development and maintenance of DC symptoms, remarking the urge to take more into account parental overcontrol in the assessment of CT.

RESUMO

Introduction: Despite the well-established evidence supporting the restorative potential of nature exposure, the neurophysiological underpinnings of the restorative cognitive/emotional effect of nature are not yet fully understood. The main purpose of the current study was to investigate the association between exposure to nature and electroencephalography (EEG) functional connectivity in the distress network. Methods: Fifty-three individuals (11 men and 42 women; mean age 21.38 ± 1.54 years) were randomly assigned to two groups: (i) a green group and (ii) a gray group. A slideshow consisting of images depicting natural and urban scenarios were, respectively, presented to the green and the gray group. Before and after the slideshow, 5 min resting state (RS) EEG recordings were performed. The exact low-resolution electromagnetic tomography (eLORETA) software was used to execute all EEG analyses. Results: Compared to the gray group, the green group showed a significant increase in positive emotions (F 1; 50 = 9.50 p = 0.003) and in the subjective experience of being full of energy and alive (F 1; 50 = 4.72 p = 0.035). Furthermore, as compared to urban pictures, the exposure to natural images was associated with a decrease of delta functional connectivity in the distress network, specifically between the left insula and left subgenual anterior cingulate cortex (T = -3.70, p = 0.023). Discussion: Our results would seem to be in accordance with previous neurophysiological studies suggesting that experiencing natural environments is associated with brain functional dynamics linked to emotional restorative processes.

RESUMO

Objective: Child maltreatment (CM) is a recognized public health problem, and epidemiologic data suggest that it is a widespread phenomenon, albeit with widely varying estimates. Indeed, CM as well as child abuse (CA) and neglect (CN) are complex phenomena that are difficult to study for several reasons, including terminological and definitional problems that pose a hurdle to estimating epidemiological rates. Therefore, the main aim of this umbrella review is to revise recent review data on the epidemiology of CM, CA, and CN. A second aim was to revise the definitions used. Method: A systematic search of three databases was performed in March 2022. Recent reviews (published in the last 5 years: 2017-March 2022) addressing the epidemiological rates of CM, CA, and/or CN were included. Results: Of the 314 documents retrieved by the selected search strategy, the eligibility assessment yielded a total of 29 eligible documents. Because of the great heterogeneity among them, a qualitative rather than a quantitative synthesis was performed. Conclusions: The data from this umbrella review show that the different age groups, methods, and instruments used in the literature to collect the data on the epidemiology of CM make it difficult to compare the results. Although definitions appear to be quite homogeneous, CM categorization varies widely across studies. Furthermore, this umbrella review shows that the CM reviews considered do not examine some particular forms of CM such as parental overprotection. The results are discussed in detail throughout the paper.

RESUMO

PURPOSE: Studies have shown significant associations of dissociative symptoms with both eating and addictive disorders; however, the different forms of dissociation have been relatively understudied in relation to food addiction (FA). The main aim of this study was to investigate the association of certain forms of dissociative experiences (i.e., absorption, detachment and compartmentalization) with FA symptoms in a nonclinical sample. METHODS: Participants (N = 755; 543 women; age range: 18-65; mean age: 28.22 ± 9.99 years) were evaluated using self-report measures of FA, dissociation, eating disturbances, and general psychopathology. RESULTS: Compartmentalization experiences (defined as pathological over-segregation of higher mental functions) were independently associated with FA symptoms (ß = 0.174; p = 0.013; CI = [0.008; 0.064]) even when confounding factors were controlled for. CONCLUSION: This finding suggests that compartmentalization symptoms can have a role in the conceptualization of FA, with such two phenomena possibly sharing common pathogenic processes. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

RESUMO

Interactions between childhood trauma (CT) and dissociation can contribute to psychiatric disturbances. We explored this phenomenon in relation to behavioral addictions (BAs) in a sample (n = 633) of young adults (age: 18-34 years). Self-report measures investigating CT, dissociation, and symptoms related to gambling disorder, internet gaming disorder, problematic social media use, exercise dependence and compulsive buying were used. Scales related to BAs were summarized into a single measure ("Total Behavioral Addiction Index" - TBAI) for inferential analyses. A model analyzing the direct and indirect effects of CT on TBAI through the mediation of pathological dissociation was performed, controlling for confounding factors. Measures on CT, dissociation, and TBAI were significantly associated with each other (all p < .001). The total effect of CT on TBAI was significant (B = 0.063; CI: 0.045; 0.081); pathological dissociation significantly mediated such association (B = 0.023; CI: 0.013; 0.036). Our findings support the possibility that the interaction between CT and dissociation contributes to increase disturbances related to BAs.

RESUMO

Suicide is a major public health problem, and it is urgent to investigate its underlying clinical and psychological concomitants. It has been suggested that low mentalization skills and problematic use of the internet (PUI) are factors that can play a role in suicidal behaviors. It is possible that poor mentalization skills contribute to leading to forms of PUI, which, in turn, can represent triggers for suicidal ideation (SI). We tested this hypothesis through a quantitative and cross-sectional study on a sample (n = 623) of young adults (age range: 18−34). Self-report measures investigating symptoms related to Social Media Addiction (SMA), Internet Gaming Disorder (IGD), mentalization capacity, and SI were used. A single mediation analysis with two mediators was carried out to evaluate the direct and indirect effects of mentalization on SI through the mediating role of SMA- and IGD-related symptoms, controlling for potential confounding factors (e.g., socio-demographic and addiction-related variables). The four explored variables were significantly associated with each other (all p < 0.001) across all subjects; the mediational model showed that the total effect of mentalization on SI was significant (B = −0.821, SE = 0.092 (95% CI: −1.001; −0.641)) and that both SMA- (B = −0.073, SE = 0.034 (95% CI: −0.145; −0.008)) and IGD-related symptoms (B = 0.046, SE = 0.027 (95% CI: −0.107; −0.001)) were significant mediators of such association. Our findings support the possibility that PUI severity plays a relevant role in mediating the association between low mentalization skills and levels of SI.

RESUMO

The main aim of the study was to examine how brain network metrics change after retrieval of attachment memories in individuals with unresolved/disorganized (U/D) attachment-related state of mind and those with organized/resolved (O/R) state of mind. We focused on three main network metrics associated with integration and segregation: global (Eglob) efficiency for the first function, local (Eloc) efficiency and modularity for the second. We also examined assortativity and centrality metrics. Electroencephalography (EEG) recordings were performed before and after the Adult Attachment Interview (AAI) in a sample of 50 individuals previously assessed for parenting quality. Functional connectivity matrices were constructed by means of the exact Low-Resolution Electromagnetic Tomography (eLORETA) software and then imported into MATLAB to compute brain network metrics. Compared to individuals with O/R attachment-related state of mind, those with U/D show a significant decrease in beta Eglob after AAI. No statistically significant difference among groups emerged in Eloc and modularity metrics after AAI, neither in assortativity nor in betweenness centrality. These results may help to better understand the neurophysiological patterns underlying the disintegrative effects of retrieving traumatic attachment memories in individuals with disorganized state of mind in relation to attachment.

RESUMO

INTRODUCTION: Although the study of the Triple Network (TN) model has gained attention in the exploration of stress-related processes, the neurophysiological mechanisms of TN in relation to perceived stress have been relatively understudied in nonclinical samples so far. The main objective of the present study was to investigate, in a sample of university students, the association of perceived stress with resting state electroencephalography (EEG) functional connectivity in the TN. METHODS: Ninety university students (40 males and 50 females; mean age 22.30 ± 2.43 years; mean educational level 16.60 ± 1.62 years) were enrolled. EEG data were analyzed through the exact low-resolution electromagnetic tomography (eLORETA). RESULTS: Higher levels of perceived stress were associated with decreased delta EEG connectivity within the central executive network (CEN) and between the CEN and the salience network (SN). Higher levels of perceived stress were also associated with decreased theta EEG connectivity between the CEN and the SN. The associations between perceived stress and EEG connectivity data were significant even when relevant confounding factors (i.e., sex, age, educational level, and psychopathological symptoms) were controlled for. DISCUSSION: Taken together, our results suggest that higher levels of perceived stress are associated with a dysfunctional synchronization within the CEN and between the SN and the CEN. This functional pattern might in part reflect the negative impact of high levels of perceived stress on cognitive functioning.

RESUMO

Need for Cognitive Closure (NCC) is a construct referring to the desire for predictability, unambiguity and firm answers to issues. Neuroscientific literature about NCC processes has mainly focused on task-related brain activity. According to the Triple Network model (TN), the main aim of the current study was to investigate resting state (RS) electroencephalographic (EEG) intra-network dynamics associated with NCC. Fifty-two young adults (39 females) were enrolled and underwent EEG recordings during RS. Functional connectivity analysis was computed through exact Low-Resolution Electromagnetic Tomography (eLORETA) software. Our results showed that higher levels of NCC were associated with both i) decreased alpha EEG connectivity within the Central Executive Network (CEN), and ii) increased delta connectivity within the Default Mode Network (DMN). No significant correlations were observed between NCC and functional connectivity in the Salience Network (SN). Our data would seem to suggest that high levels of NCC are characterized by a specific communication pattern within the CEN and the DMN during RS. These neurophysiological patterns might reflect several typical NCC-related cognitive characteristics (e.g., lower flexibility and preference for habitual and rigid response schemas).

RESUMO

Several studies have shown how COrona VIrus Disease 2019 (COVID-19) and the consequent isolation and quarantine measures could affect physical and mental well-being. Therefore, the increased request for support and assistance represents a critical challenge for clinicians requiring a reorganization of care systems. In this regard, online counselling has been identified as a useful tool in providing psychological assistance and support. Thus, the main purpose of the current study was to investigate the clinical usefulness of a single online counselling session in reducing psychopathological symptoms (i.e., state anxiety and negative affect) and increasing individual well-being and positive affect during the first Italian lockdown. Fifty-three subjects were enrolled and randomly assigned to receive an online counselling session [Online Counselling Group (OCG) = 26] or to act as controls [Waiting List Group (WLG) = 27]. In the post-assessment, compared to WLG, the OCG showed a significant decrease in negative affect (18.04 ± 6.30 vs. 30.26 ± 8.61; F1:47 = 29.45; p < .001; dppc2 = .92) and state anxiety (36.65 ± 8.35 vs. 48.04 ± 11.51; F1:47 = 17.86; p < .001; dppc2 = .49). Taking into account the cyclical nature of COVID-19, with the possibility of new peaks and waves, it would be appropriate to consider the versatility and usefulness of online psychological counselling in the management of COVID-19-related distress.

RESUMO

PURPOSE: Although the association between problematic use of the internet and eating disorders (EDs) in young adults has been previously established, its underlying mechanisms have not been completely clarified. It has been suggested that exposure to idealized very thin and toned body images (e.g., "thinspiration" and "fitspiration" trends) on social media might lead to increased feelings of body dissatisfaction which, in turn, can represent a trigger for EDs. We have tested this hypothesis in a sample (N = 721) of young adults (504 females, mean age: 24.13 ± 3.70 years; range 18-34). METHODS: Self-report measures investigating symptoms related to social media addiction (SMA), muscle dysmorphia (MD), and EDs were used. A mediational model analyzing the direct and indirect effects of SMA-related symptoms on ED-related symptoms through the mediating role of MD-related symptoms was performed controlling for confounding factors (e.g., socio-demographic variables, substances use, body mass index, psychopathological distress). RESULTS: The model showed that the total effect of SMA-related symptoms on ED-related symptoms was significant (B = 0.213; p = 0.022) and that this association was mediated by MD-related symptoms (B = 0.083; p = 0.021). DISCUSSION: Our findings support the possibility that MD-related symptoms play a relevant role in mediating the association between SMA severity and ED pathology. LEVEL OF EVIDENCE: Level III, evidence obtained from well-designed cohort or case-control analytic studies.

RESUMO

AIMS: We investigated the association among triple network electroencephalographic (EEG) functional connectivity, dissociative symptoms, and childhood trauma (CT) in a sample of university students. SAMPLING AND METHODS: Seventy-six participants (30 males and 46 females; mean age 22.12 ± 2.35) completed self-report measures investigating dissociative symptoms, CT, and depressive symptoms. Participants also performed an eyes-closed resting-state EEG recording. EEG analyses were conducted through the exact low-resolution electromagnetic tomography (eLORETA) software. RESULTS: A 2-step cluster analysis revealed 2 groups: participants (N = 23) with high dissociative-traumatic dimension symptoms (DTD+) and participants (N = 53) with low DTD symptoms (DTD-). Compared to DTD- subjects, DTD+ participants showed decreased theta connectivity between the salience network (SN) and central executive network (CEN), specifically between the right anterior insula and the left posterior parietal cortex. No significant correlation was detected between EEG data and clinical variables. CONCLUSION: Our results raise the possibility of a dysfunctional connectivity pattern occurring between the SN and CEN in individuals with high DTD symptoms. Such connectivity pattern might reflect the neuropsychophysiological disintegration related to pathological dissociation.

RESUMO

Social distancing and home confinement during the first wave of Covid-19 have been essential to helping governments to flatten the infection curve but raised concerns on possible negative consequences such as prolonged isolation or sedentary lifestyles. In this scenario, gardening activities have been identified as a plausible tool to buffer the mental health consequences of forced home confinement. In this paper, we investigate the relation between gardening and psychopathological distress during the lockdown of the first wave of Covid-19 in Italy. It is hypothesized that engagement in gardening activities promotes psychological health, through a reduction of Covid-related stress. An online survey was administered through sharing using social media to N = 303 participants during the March-May 2020 lockdown in Italy, measuring Covid-19 related distress, psychopathological distress, engagement in gardening activities plus a series of socio-demographic and residential covariates. As expected, a mediation model tested using a bootstrapping procedure showed that gardening is related to lower psychopathological distress through decreased Covid-19 related distress. Interestingly, results also showed that psychopathological distress was higher for women and unmarried respondents, and negatively associated with age and square meters per person at home. The theoretical and practical implications for social policies contrasting the Covid-19 pandemic are discussed.

RESUMO

Background: Several scholars hypothesize that one of the most negative impacts of the coronavirus disease 2019 (COVID-19) crisis would concern the increase of prevalence and severity of both substances and behavioral addiction. Despite the general concerns about the increase of prevalence and severity of addictions related to the COVID-19 emergency, few data are still available. Thus, the main aim of this study was to investigate the association between COVID-19 related distress and: (i) alcohol problems, (ii) social media addiction (SMA) symptoms, (iii) food addiction (FA) symptoms. Methods: A national online-survey was carried out during the Italian lockdown (i.e., 9 March 2020-4 May 2020). In the current study, 1,519 participants (365 men and 1,154 women, mean age: 28.49 ± 10.89 years) were included. The survey included socio-demographic related items (e.g., age, sex, residential regions, education level, civil status, tobacco use, etc.), as well as ad-hoc developed questions aimed to investigate COVID-19 related variables (e.g., isolation/quarantine, personal diagnosis to COVID-19, friends or relatives with COVID-19 diagnosis, etc.). Participants also completed the following self-report measures in order to investigate: the psychological impact of COVID-19, alcohol problems, SMA symptoms, FA symptoms, and impulsivity. Results: The psychological impact of COVID-19 was independently associated with alcohol problems (ß = 0.058, p = 0.043), SMA symptoms (ß = 0.259, p < 0.001), and FA symptoms (ß = 0.150, p < 0.001). Conclusion: Taken together, our results seem to confirm the general concerns about the negative impacts of the COVID-19 emergency on addictive behaviors, suggesting that this issue should be carefully monitored.

RESUMO

The main aim of the present study was to investigate the association between body shape concerns and electroencephalography (EEG) functional connectivity within body image network in a sample of university students (N = 68). EEG was recorded during 5 min of resting state. All participants were asked to complete self-report measures assessing certain psychopathological dimensions (i.e., body shape concerns, depression, anxiety, obsessive-compulsive symptoms). EEG analyses were conducted by means of the exact low-resolution electromagnetic tomography software (eLORETA). Our results showed that body shape concerns were positively associated with increased gamma functional connectivity between the left and right prefrontal cortex (PFC). Furthermore, our data revealed that this EEG pattern was independently associated with body shape concerns after controlling for potential socio-demographic and clinical confounding variables. This finding seems to suggest that increased EEG gamma connectivity between the left and right PFC might be a relevant neurophysiological alteration involved in the development and/or maintenance of dysfunctional concerns about one's body.

RESUMO

Although previous studies have reported the association between large-scale brain networks alterations and pathological anxiety, abnormalities in the dynamic interaction among the triple network model in anxiety disorders and, especially, in trait anxiety is still poorly explored. Thus, the main aim of the current study was to investigate triple network functional dynamics in subjects with high trait anxiety during resting state (RS) through electroencephalography (EEG) connectivity. Twenty-three individuals with high-trait-anxiety (HTA) and forty-five participants with low-trait-anxiety (LTA) were enrolled. EEG analyses were conducted by means of the exact Low-Resolution Electromagnetic Tomography software (eLORETA). Compared to LTA participants, HTA subjects showed a decrease of alpha connectivity within the salience network (SN), between the dorsal anterior cingulate cortex (dACC) and both left and right anterior insula (AI). Furthermore, SN functional connectivity strength was negatively correlated with higher trait anxiety, even when controlling for potential confounding variables (e.g., depressive and obsessive-compulsive symptoms). Taken together, our results point out a specific functional connectivity pattern in HTA individuals, which consists in a dysfunctional communication within the SN, specifically in the AI-dACC pathway. This functional pattern could underline, at rest, saliency detection and brain correlates of altereted emotion regulation and cognitive control processes typically involved in anxiety.

RESUMO

Religious coping to psychological stress has been linked to positive outcomes on both physical and mental health, but no studies have explored its neurophysiological correlates. Ninety-six participants (43 men and 53 women, mean age: 22.30 ± 2.48 years) were enrolled in the present study; they underwent an evaluation of coping with the brief version of the Coping Orientation to Problems Experienced (brief-COPE) scale and performed an eyes-closed resting state electroencephalographic (EEG) recording. EEG analyses were conducted with the exact Low-Resolution Electromagnetic Tomography software (eLORETA). Positive correlations between religious coping and EEG activity were observed in the theta frequency band in the right hemisphere, specifically in the superior temporal, inferior frontal, and middle temporal gyri. Religious coping scores were significantly positively associated with active coping and positive reframing coping strategies, with the latter not being significantly associated with EEG data. Taken together our results contribute to increase the knowledge on the neurophysiological concomitants of religious coping to stress.

RESUMO

An increasing body of experimental data have suggested that aberrant functional interactions between large-scale networks may be the most plausible explanation of psychopathology across multiple mental disorders, including substance-related and addictive disorders. In the current research, we have investigated the association between problematic cannabis use (PCU) and triple-network electroencephalographic (EEG) functional connectivity. Twelve participants with PCU and 24 non-PCU participants were included in the study. EEG recordings were performed during resting state (RS). The exact Low-Resolution Electromagnetic Tomography software (eLORETA) was used for all EEG analyses. Compared to non-PCU, PCU participants showed an increased delta connectivity between the salience network (SN) and central executive network (CEN), specifically, between the dorsal anterior cingulate cortex and right posterior parietal cortex. The strength of delta connectivity between the SN and CEN was positively and significantly correlated with higher problematic patterns of cannabis use after controlling for age, sex, educational level, tobacco use, problematic alcohol use, and general psychopathology (rp = 0.40, p = 0.030). Taken together, our results show that individuals with PCU could be characterized by a specific dysfunctional interaction between the SN and CEN during RS, which might reflect the neurophysiological underpinnings of attentional and emotional processes of cannabis-related thoughts, memories, and craving.

RESUMO

PURPOSE: To explore electroencephalographic (EEG) alterations in young women with different eating disorder (ED) psychopathology levels. METHODS: Thirty-seven young women completed general and ED psychopathology (i.e., the ED Examination Questionnaire; EDE-Q) measures. EEG power spectra data were investigated in two conditions: (a) 5 min of resting state (RS) and (b) 5 min of RS after a single taste of a milkshake (ML-RS). EEG analyses were performed using exact Low-Resolution Electromagnetic Tomography software (eLORETA). RESULTS: Cluster analysis performed on the EDE-Q responses revealed a group of 17 women with high levels of ED pathology falling into the subclinical (i.e., sub-threshold) EDs category and a group of 20 women with low levels of ED pathology (controls). In the RS conditions, no significant modifications were observed between groups. Compared to controls, women with subclinical EDs showed an increase in theta activity in the parieto-occipital areas in the ML-RS condition. After controlling for body mass index and general psychopathology, theta activity in these brain structures was positively associated with EDE-Q global and subscale (restraint, shape and weight concern) scores. CONCLUSIONS: Our results may reflect the neurophysiological substrate of ED psychopathology core features like shape/weight concerns. Previous brain imaging and qEEG studies with full-syndrome ED patients also underscored the involvement of parieto-occipital areas in ED pathophysiology. These studies also found brain alterations in the RS condition, not observed here. This is notable given that full-syndrome and subclinical EDs are considered as different manifestations of the same disease along a severity spectrum. LEVEL OF EVIDENCE: Level V, cross-sectional, electroencephalographic, descriptive study.

RESUMO

BACKGROUND: Frontal alpha asymmetry (FAA) has been widely investigated in depressive disorders (DDs) with contradictory and not conclusive results. The main aim of the current study was to explore the association between a new neurophysiological index, the so-called frontal alpha connectivity asymmetry index (FACA-I), and depressive symptoms. METHODS: One hundred and thirteen participants (45 men and 68 women, mean age: 22.83 ±â€¯2.26 years) were enrolled. Electroencephalographic (EEG) recordings were performed during 5 min of resting state (RS). FACA-I was computed by subtracting connectivity at left frontal regions from right frontal regions and dividing by their sum. RS FAA were also computed and compared to the FACA-I in all analyses. RESULTS: After controlling for the presence of potential confounding variables (i.e., sex, age and anxiety symptoms), only FACA-I scores between medial prefrontal cortex and subgenual anterior cingulate cortex were negatively associated with both somatic and cognitive/affective depressive symptoms and were lower in individuals with significant level of depressive symptoms. LIMITATIONS: We focused on a sample of university students with no formal diagnosis of depression and we did not assess FAA and FACA-I during cognitive and/or emotional tasks, which make our interpretation specific to the RS condition. CONCLUSIONS: Taken together our data suggest that alpha connectivity asymmetry between medial prefrontal cortex and subgenual anterior cingulate cortex may be a useful neurophysiological index in the assessment of depressive symptoms.
