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

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

Unique diagnostic signatures of concussion in the saliva of male athletes: the Study of Concussion in Rugby Union through MicroRNAs (SCRUM).

OBJECTIVE: To investigate the role of salivary small non-coding RNAs (sncRNAs) in the diagnosis of sport-related concussion. METHODS: Saliva was obtained from male professional players in the top two tiers of England's elite rugby union competition across two seasons (2017-2019). Samples were collected preseason from 1028 players, and during standardised head injury assessments (HIAs) at three time points (in-game, post-game, and 36-48 hours post-game) from 156 of these. Samples were also collected from controls (102 uninjured players and 66 players sustaining a musculoskeletal injury). Diagnostic sncRNAs were identified with next generation sequencing and validated using quantitative PCR in 702 samples. A predictive logistic regression model was built on 2017-2018 data (training dataset) and prospectively validated the following season (test dataset). RESULTS: The HIA process confirmed concussion in 106 players (HIA+) and excluded this in 50 (HIA-). 32 sncRNAs were significantly differentially expressed across these two groups, with let-7f-5p showing the highest area under the curve (AUC) at 36-48 hours. Additionally, a combined panel of 14 sncRNAs (let-7a-5p, miR-143-3p, miR-103a-3p, miR-34b-3p, RNU6-7, RNU6-45, Snora57, snoU13.120, tRNA18Arg-CCT, U6-168, U6-428, U6-1249, Uco22cjg1,YRNA_255) could differentiate concussed subjects from all other groups, including players who were HIA- and controls, immediately after the game (AUC 0.91, 95% CI 0.81 to 1) and 36-48 hours later (AUC 0.94, 95% CI 0.86 to 1). When prospectively tested, the panel confirmed high predictive accuracy (AUC 0.96, 95% CI 0.92 to 1 post-game and AUC 0.93, 95% CI 0.86 to 1 at 36-48 hours). CONCLUSIONS: SCRUM, a large prospective observational study of non-invasive concussion biomarkers, has identified unique signatures of concussion in saliva of male athletes diagnosed with concussion.

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

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

Obsessive-Compulsive Tendencies, Self/Other Perception, Personality, and Suicidal Ideation in a Non-clinical Sample.

Research on the risk factors for SI in adults with OC tendencies is limited, and it is still unclear whether the association between OC tendencies and SI in non-clinical individuals exists. The goal of the present study was to test the associations between OC tendencies, self/other perception, personality traits, depressive symptoms and SI among a non-clinical adult population. We investigated an Italian sample of 337 adults, who were administered a set of self-report questionnaires to assess obsessive-compulsive tendencies, depression, self/other perception, personality traits, and hopelessness. Confirmatory factor analyses (CFA) were performed. In the final model we found that personality, obsessive-compulsive factor and suicidal ideation were significantly correlated with each other: personality correlated negatively with obsessive-compulsive factor and suicidal ideation, while obsessive-compulsive factor and suicidal ideation resulted as strongly positively associated. Our results highlight the importance of assessing OC tendencies, negative self/other perception and SI. Understanding their role and interplay will allow for the development and implementation of more advanced prevention and treatment policies.

Brain Emotion Systems, Personality, Hopelessness, Self/Other Perception, and Gambling Cognition: A Structural Equation Model.

The aim of this study was to explore the relations between gambling, brain emotion systems, personality, self/other perception, and hopelessness in an Italian community. Dimensions of gambling, positive and negative emotions, self/other perception, personality and hopelessness were assessed in a community sample of 235 adults aged 19-59 years. Two structural models were tested. We found a significant correlation between problem gambling and impulsivity, which in association with aggressivity and negative personality dimensions may help explain the psychopathology factor, i.e. a latent variable involving neurotic personality, hopelessness, high sensation seeking, low metacognitive responsiveness, and disorganized patterns of interpersonal relationships. These results contribute to develop a theoretical framework of gambling in relation with personality factors and provide a new approach for clinical intervention of problem gambling that relies on a solid multidimensional perspective.

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

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

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

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

Occupational stress and psychopathology in health professionals: an explorative study with the multiple indicators multiple causes (MIMIC) model approach.

Occupational stress is a multivariate process involving sources of pressure, psycho-physiological distress, locus of control, work dissatisfaction, depression, anxiety, mental health disorders, hopelessness, and suicide ideation. Healthcare professionals are known for higher rates of occupational-related distress (burnout and compassion fatigue) and higher rates of suicide. The purpose of this study was to explain the relationships between occupational stress and some psychopathological dimensions in a sample of health professionals. We investigated 156 nurses and physicians, 62 males and 94 females, who were administered self-report questionnaires to assess occupational stress [occupational stress inventory (OSI)], temperament (temperament evaluation of Memphis, Pisa, Paris, and San Diego autoquestionnaire), and hopelessness (Beck hopelessness scale). The best Multiple Indicators Multiple Causes model with five OSI predictors yielded the following results: χ2(9) = 14.47 (p = 0.11); χ2/df = 1.60; comparative fit index = 0.99; root mean square error of approximation = 0.05. This model provided a good fit to the empirical data, showing a strong direct influence of casual variables such as work dissatisfaction, absence of type A behavior, and especially external locus of control, psychological and physiological distress on latent variable psychopathology. Occupational stress is in a complex relationship with temperament and hopelessness and also common among healthcare professionals.

Suicide risk and psychopathology in immigrants: a multi-group confirmatory factor analysis.

BACKGROUND: Immigrants may experience several negative consequences as a result of their migration including discrimination, unsatisfactory economic conditions, and rejection from the host countries, which may contribute to psychiatric illness and vulnerability to suicidal behaviors. The purpose of the current study was to determine whether or not the theorized components of measured dimensions of suicide risk and psychopathology vary across samples of Italians and immigrants. METHODS: We investigated 237 Italians and 234 immigrants, who were administered self-report questionnaires to assess temperament (TEMPS-A), hopelessness (BHS), personality (EPQ-R), and self-other perception (9AP). RESULTS: Multi-group confirmatory factor analyses were conducted, which yielded a final model with an excellent fit to the data (χ (53) (2)  = 57.56; CFI = 0.994; RMSEA = 0.014). This final model fits significantly better than the previously tested models and indicated that the same pattern of relationships was found between suicide risk and psychopathology across both groups. CONCLUSIONS: Although immigrants represent a unique population and may experience specific stressors contributing to psychopathology and suicide risk, our findings suggest that the samples of Italians and immigrants may be more similar on the study variables under investigation than previously thought. Implications are offered for the improved identification and treatment of immigrants and resident citizens in Europe in general and in Italy in particular.

Hopelessness, temperament, anger and interpersonal relationships in Holocaust (Shoah) survivors' grandchildren.

The psychiatric literature is divided with regard to the long-term psychological effects associated with Holocaust (Shoah) experiences because the findings of clinical and empirical studies often contradict each other. Despite case reports of emotional sequelae related to intergenerational transmission of trauma, recent empirical research has suggested that offspring of survivors of the Shoah did not differ from other children and found no evidence that traumatic experiences of survivors of the Shoah affected their children's and grandchildren's adjustment. To shed light on some of the differences between the empirical and clinical observations, the present study set out to compare the grandchildren of survivors of the Shoah and persons of the same age whose families had not been through the Shoah experience. This study compared the two groups on some psychological dimensions relevant to traumatic sequelae: hopelessness, temperament, personality, attitudes, and interpersonal expectations. Subjects were 124 equally divided among the Shoah survivors' grandchildren and comparison groups; we administered to all subjects TEMPS-A Rome, Beck Hopelessness Scale, State-Trait Anger Expression Inventory, and 9AP (9 Attachment Profile). We found no differences between two groups in Hopelessness, Dysthimic/Cyclotimic/Anxious, Hyperthimic temperament, and self-perception; instead the Shoah survivors' grandchildren have a view of the other as rejecting, hostile, submissive, insecure, unreliable, and competitive in the interpersonal relationships. The Shoah survivors' grandchildren are similar to controls in affective temperament, hopelessness and self-perception, but they are more irritable and angry than controls, and their perception about others is deeply negative. Attribution theory was used to elucidate these findings.

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

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

Temperament, insecure attachment, impulsivity, and sexuality in women in jail.

BACKGROUND: Women constitute only a small proportion of inmates, but several studies have shown that they have higher rates of psychiatric disturbance than incarcerated men and community samples. Mental health treatment is necessary to prevent severe illness and suicide in these women. METHODS: The convenience sample consisted of 40 female detainees and 40 controls who were administered self-report questionnaires to assess temperament (TEMPS-A), insecure attachment (ECR), impulsivity (BIS-11), and sexual behavior (SESAMO). RESULTS: The incarcerated women had higher levels of affective temperament (except for hyperthymia), avoidance, anxiety, impulsivity, and psychosexual issues than the female community sample. CONCLUSIONS: Many interrelated emotional and affective disturbances affect the physical and psychological well-being of women in jail, and it is possible that these problems may lead to suicide. Health professionals need to develop gender-specific therapeutic interventions for women in jail.

Relationship between Temperament, Depression, Anxiety, and Hopelessness in Adolescents: A Structural Equation Model.

The purpose of this study was to test the validity of affective temperaments for predicting psychiatric morbidity and suicide risk, using a two-factor model to explain the relationships between temperament, anxiety, depression, and hopelessness. We investigated 210 high school students, 103 males and 107 females, 18-19 years old, who were administered self-report questionnaires to assess temperament (TEMPS-A), depression (BDI-II), anxiety (STAI) and hopelessness (BHS). The final structural model had a good fit with the data, with two factors significantly correlated, the first labeled unstable cyclothymic temperament including Dysthymic/Cyclothymic/Anxious temperament, Irritable temperament and Depression, and the second labeled Demoralization including Anxiety (State/Trait) and Hopelessness. Depression, anxiety and hopelessness are in a complex relationship partly mediated by temperament.

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

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