The developmental course of adolescent paranoia: a longitudinal analysis of the interacting role of mistrust and general psychopathology.

Paranoia is the erroneous idea that people are targeting you for harm, and the cognitive model suggests that symptoms increase with emotional and relational distress. A factor potentially associated with paranoia is mistrust, a milder form of suspiciousness. This study investigated the longitudinal course of non-clinical paranoia in a sample of 739 students (age range 10-12 at baseline assessment, 12-14 at second assessment) using data from the Social Mistrust Scale (SMS) and the paranoia subscale of the Specific Psychotic Experiences Questionnaire (SPEQ). Prevalence of mistrustful and high paranoia children was 14.6 and 15% respectively. Independently, baseline internalizing symptoms (b = 0.241, p < 0.001) and mistrust (b = 0.240, p < 0.001) longitudinally predict paranoia after controlling for confounders. The interaction of mistrust and internalizing symptoms at T1 increases the possibility of the onset of paranoia at T2. Therefore, the effect of mistrust on paranoia is more marked when internalizing symptoms are higher. Our results confirm the role of mistrust as a factor involved in the developmental trajectory of paranoia in adolescence, enhanced by the presence of internalizing symptoms. The implications of these results are both theoretical and clinical, as they add developmental information to the cognitive model of paranoia and suggests the assessment and clinical management of mistrust and internalizing symptoms in youth may be useful with the aim of reducing the risk of psychotic experiences.

Assessing Callous-Unemotional Traits Across Early Adolescence: Further Evaluation of Short Versions.

Literature on the Inventory of Callous-Unemotional (ICU) traits has suggested different versions of the instrument for assessing these traits during development. However, consensus on the instrument version and the best factorial solution remains a matter of debate, with only a few studies having validated ICU versions from a longitudinal perspective. The current study aims to contribute to the literature by comparing ICU models in a longitudinal sample of early adolescents (N = 739; 70.6% of eligible subjects, 371 females and 368 males, in the 6th grade at baseline assessment and in the 8th grade at the second assessment). We tested the validity of various versions of the ICU scales and their respective dimensions by conducting a series of confirmatory factor analyses to verify the factor structure, alongside assessments of internal consistency. For the best-fitting structure, we then analyzed gender and longitudinal invariance in addition to construct and predictive validity, using internalizing and externalizing criteria as well as prosocial behavior. From the comparative analysis, it emerged that the abbreviated 11-item ICU scale version displayed overall better data fit than the full 24-item version. Moreover, its confirmed gender invariance underscores its applicability across genders within the studied age group. With regard to longitudinal invariance, our findings advise caution when comparing ICU scores across early adolescence. Practical implications are discussed.

The association between social isolation, loneliness and psychological problems in young adults: A study during the acute phase of COVID-19 in Italy.

During the COVID-19 pandemic, governments had to impose social isolation measures to safeguard the citizens' health. However, this could have affected psychological problems. The aim of the present study was to investigate the psychological effects associated with social and emotional isolation during the acute phase of the COVID-19 in Italy. To this purpose, the degree of social isolation and loneliness and the presence of psychological problems (externalising and internalising) were investigated online in a sample of 395 young adults (18-30 years; 57% women). Results confirmed the relevant association between social isolation, loneliness and psychological problems, in both internalising and externalising dimensions. Particularly, loneliness showed the strongest association. Moreover, consistently with surveys conducted during the COVID-19-era, data highlighted that men were more vulnerable to social isolation and loneliness than women. These results underline the need for adequate interpersonal support during moments of isolation to prevent negative effects on psychological problems.

Functional near-infrared spectroscopy is a useful tool for multi-perspective psychobiological study of neurophysiological correlates of parenting behaviour.

The quality of the relationship between caregiver and child has long-term effects on the cognitive and socio-emotional development of children. A process involved in human parenting is the bio-behavioural synchrony that occurs between the partners in the relationship during interaction. Through interaction, bio-behavioural synchronicity allows the adaptation of the physiological systems of the parent to those of the child and promotes the positive development and modelling of the child's social brain. The role of bio-behavioural synchrony in building social bonds could be investigated using functional near-infrared spectroscopy (fNIRS). In this paper we have (a) highlighted the importance of the quality of the caregiver-child relationship for the child's cognitive and socio-emotional development, as well as the relevance of infantile stimuli in the activation of parenting behaviour; (b) discussed the tools used in the study of the neurophysiological substrates of the parental response; (c) proposed fNIRS as a particularly suitable tool for the study of parental responses; and (d) underlined the need for a multi-systemic psychobiological approach to understand the mechanisms that regulate caregiver-child interactions and their bio-behavioural synchrony. We propose to adopt a multi-system psychobiological approach to the study of parental behaviour and social interaction.

Linking perception of bodily states and cognitive control: the role of interoception in impulsive behaviour.

Interoception and impulsivity are two multi-dimensional constructs and although the role of interoception in impulsiveness has been previously reported, it is not clear whether their different facets are related to each other. In the present study, we aimed at bridging this gap by investigating the relationships between interoception and impulsivity in the light of their multi-dimensional nature. To this aim, we conducted a cross-task comparison and assessed in the same sample of healthy participants, interoceptive accuracy, by the heartbeat perception task, interoceptive sensibility, by a self-reported measure, "hot" impulsivity, by a behavioural task of risk taking, and "cool" impulsivity, by a go/no-go task. Also, we assessed trait impulsivity by a self-report measure. We found that interoceptive sensibility contributed to "hot" impulsivity, while interoceptive accuracy was related to non-planning trait impulsivity. These findings underscore the need to investigate at a finer grain the relationships between these two complex, multi-dimensional constructs.

Effects of social exclusion and maternal rejection on Children's high-caloric food consumption.

Research has shown that the quality of interpersonal relationships plays an important role in influencing childhood obesity-risk behavior. However, studies conducted so far have focused mostly on self-report data. But they rarely control for the effect of experimentally-induced social rejection or perceived maternal rejection. The aim of this study was to investigate the effects of the quality of the maternal relationships as well as experimentally-induced social rejection on children's motivation to consume high-caloric food. Eighty children (8-12 years of age) and their mothers participated in an experimental study. Participants were randomly assigned to a social inclusion (acceptance) or exclusion (rejection) condition in a computer-based ball-toss game (Cyberball). After completing the Cyberball game, children were presented with high-caloric food and were evaluated on the amount of the food they consumed. Participants also completed a self-report questionnaire assessing their perceptions of their mothers' acceptance-rejection. Further, mothers' Body Mass Index (BMI) was measured, and a semi-structured interview was conducted to assess the tendency of mothers to regulate their child's stress with food. Results showed that the consumption of high-caloric food was directly influenced by the children's perceptions of maternal acceptance-rejection, and by the experience of brief, experimentally-induced social exclusion (rejection). Additionally, children's consumption of high-caloric food was related to their mothers' use of food to help regulate children's distress, and by the children's own BMI. The results document the importance of affective-relational experiences in the development of childhood obesity. The results also highlight the apparent fact that regardless of individual and family characteristics, the experience of even short-term social rejection can activate obesity-risk behaviors which deplete children's self-regulatory mechanisms, thereby resulting in more consumption of high-caloric food.

The effects of autistic traits and academic degree on visuospatial abilities.

In the present study, we were interested to investigate how autistic traits (including systemizing and empathy) and academic degree influence individuals' visuospatial abilities. To this end, 352 university students completed the Autism Spectrum Quotient (AQ), the Empathy Quotient, the Systemizing Quotient (SQ) and visuospatial tests measuring figure disembedding and mental rotation of two-dimensional figures. Engineering-design students (architecture and engineering) were the most accurate in disembedding and mentally rotating figures, followed by students of physical sciences (computer science, chemistry, physics, etc.) and fact-based humanities (languages, classics, law); biological (psychology and neuroscience, etc.) and systems-based social scientists (economics and commerce) were the least accurate. Engineering-design students also showed higher SQ scores with respect to the other four academic degree subjects, with students of biological sciences showing lower SQ scores. Importantly, results from a path analysis revealed that SQ (but not AQ) exerted an indirect effect on figure disembedding and mental rotations through the influence of the academic degree. Thus, the present findings reveal shady differences in systemizing degree and visuospatial performance within systemizing-based degree subjects. Implications for education are discussed.

Psychological maladjustment mediates the link between remembrances of parental rejection in childhood and loneliness in adulthood: A cross-cultural comparative study.

Drawing stimulus from interpersonal acceptance-rejection theory, this multicultural study examined relations between men's versus women's remembrances of maternal and paternal acceptance-rejection in childhood and their current level of loneliness, as mediated by adults' self-reported psychological maladjustment. Adults (N = 899) from five nations (Iraq, Italy, the Netherlands, Pakistan, and the United States) responded to the Adult version of the Parental Acceptance-Rejection Questionnaire-short form for mothers and fathers, the Adult version of the Personality Assessment Questionnaire-short form, and the Interpersonal Acceptance-Rejection Loneliness Scale. Adults' remembrances of maternal and paternal rejection in childhood significantly and independently predicted feelings of loneliness but remembered paternal rejection was more strongly related to these feelings than were remembrances of maternal rejection. Psychological maladjustment fully mediated the effect of remembered maternal rejection but only partially mediated the effect of remembered paternal rejection on loneliness. There were no significant differences in these results across the five countries or genders. Overall, the results suggest that adults' remembrances of parental rejection in childhood-along with the theoretically expected development of psychological maladjustment-are likely to be associated panculturally with the experience of loneliness in adulthood.

Implicit associations to infant cry: Genetics and early care experiences influence caregiving propensities.

Adults' sensitive appraisal of and response to infant cry play a foundational role in child development. Employing a gene × environment (G × E) approach, this study investigated the interaction of genetic polymorphisms of the serotonin transporter gene (5-HTTLPR) and oxytocin receptor genes (OXTR; rs53576, rs2254298) with early parental care experiences in influencing adults' implicit associations to infant cry. Eighty nulliparous adults (40 females, 40 males) responded to the Parental Acceptance-Rejection Questionnaire (PARQ), a measure of early care experiences, and participated in a Single Category Implicit Association Task (SC-IAT) to measure implicit associations to infant cry. Independent of parental experience, the valence of the implicit response to infant cry is associated with the serotonin transporter gene polymorphism (5-HTTLPR), with LL-carriers showing more positive implicit associations than S-carriers. OXTR rs53576 moderated the relation between parental rejection and implicit appraisal of infant cry: A-carriers who experienced negative early care showed an implicit positive appraisal of infant cry, whereas in GG carriers, positive early care experiences were associated with an implicit positive reaction to infant cry. OXTR rs2254298 had no relation to implicit associations to infant cry or to early care experiences. These findings cast light on the possible interplay of genetic inheritance and early environment in influencing adults' responses to infant cry that may be incorporated into screening protocols aimed at identifying at-risk adult-infant interactions.

Normative data of the Rey-Osterrieth Complex Figure for Italian-speaking elementary school children.

The Rey-Osterrieth Complex Figure Test (ROCF) is a widely used neuropsychological test for the evaluation of drawing disorders in different clinical populations, and, in particular, in persons with neurodevelopmental disorders. The aim of the present study is to provide normative data for ROCF copying (ROCF-Direct copy) and drawing from memory (ROCF-Immediate recall) in Italian-speaking children. The sample consisted of 348 children (147 males and 199 females), aged 7-11 years, recruited from elementary schools in Southern Italy. Normative data were gathered from 312 participants fulfilling the inclusion criteria, and estimated centiles were obtained according to the LMS method providing normalized growth centile standards. Results showed a significant effect of age on performance in both tasks, with a steady increase of drawing accuracy, whereas participants' gender and mean level of parental education did not exert any significant effect. Thus, normative data were stratified by age, and percentile scores were provided allowing a practical use of the ROCF for the clinical evaluation of drawing abilities in both typical and atypical children.

Mental simulation of drawing actions enhances delayed recall of a complex figure.

Motor simulation implies that the same motor representations involved in action execution are re-enacted during observation or imagery of actions. Neurofunctional data suggested that observation of letters or abstract paintings can elicit simulation of writing or drawing gestures. We performed four behavioural experiments on right-handed healthy participants to test whether observation of a static and complex geometrical figure implies re-enactment of drawing actions. In Experiment 1, participants had to observe the stimulus without explicit instruction (observation-only condition), while performing irrelevant finger tapping (motor dual task), or while articulating irrelevant verbal material (verbal dual task). Delayed drawing of the stimulus was less accurate in the motor dual-task (interfering with simulation of hand actions) than in verbal dual-task and observation-only conditions. In Experiment 2, delayed drawing in the observation only was as accurate as when participants encoded the stimulus by copying it; in both conditions, accuracy was higher than when participants were instructed to observe the stimulus to recall it later verbally (observe to recall), thus being discouraged from engaging motor simulation. In Experiment 3, delayed drawing was as accurate in the observation-only condition as when participants imagined copying the stimulus; accuracy in both conditions was higher than in the observe-to-recall condition. In Experiment 4, in the observe-only condition participants who observed the stimulus with their right arm hidden behind their back were significantly less accurate than participants who had their left arm hidden. These findings converge in suggesting that mere observation of a geometrical stimulus can activate motor simulation and re-enactment of drawing actions.

In utero testosterone exposure influences physiological responses to dyadic interactions in neurotypical adults.

OBJECTIVE: We investigated how different levels of prenatal exposure to testosterone influence physiological reactions to dyadic interactions, hypothesising that higher levels of prenatal testosterone are linked to greater physiological responses. METHOD: Autonomic nervous system responses to dyadic interactions focussed on social or physical norms were measured. Physiological assessment of excitability (heart rate, facial temperature) and a behavioural assessment (Likert items judgements) were run on 25 neurotypical participants who had distinct testosterone exposure levels in utero. In utero exposure to testosterone was assessed measuring 2D : 4D (ratio between the lengths of the index and the ring fingers). RESULTS: Higher testosterone exposure participants showed greater physiological arousal: a greater heart rate decrease, independent from scenario type (p<0.05), and opposite facial temperature changes in response to social (increase) (vs.) physical scenarios (decrease) were found (Left-cheek: p<0.05; Right-cheek: p<0.05). CONCLUSION: These findings suggest a long-term influence of prenatal environment on adults' physiological responses during social situations.

The influence of anxiety and personality factors on comfort and reachability space: a correlational study.

Although the effects of several personality factors on interpersonal space (i.e. social space within personal comfort area) are well documented, it is not clear whether they also extend to peripersonal space (i.e. reaching space). Indeed, no study has directly compared these spaces in relation to personality and anxiety factors even though such a comparison would help to clarify to what extent they share similar mechanisms and characteristics. The aim of the present paper was to investigate whether personality dimensions and anxiety levels are associated with reaching and comfort distances. Seventy university students (35 females) were administered the Big Five Questionnaire and the State-Trait Anxiety Inventory; afterwards, they had to provide reachability- and comfort-distance judgments towards human confederates while standing still (passive) or walking towards them (active). The correlation analyses showed that both spaces were positively related to anxiety and negatively correlated with the Dynamism in the active condition. Moreover, in the passive condition higher Emotional Stability was related to shorter comfort distance, while higher cognitive Openness was associated with shorter reachability distance. The implications of these results are discussed.

Beyond Parental Acceptance and Rejection: A Commentary on the Findings From Empirical Studies on Forgiveness and Vengeance in the Muslim World.

Drawing on the framework of interpersonal acceptance-rejection theory (IPARTheory), this special issue edited by Ronald P. Rohner, Sumbleen Ali, and Jennifer E. Lansford explores forgiveness and vengeance within the context of the Muslim world. Examination of the precursors of forgiveness and vengeance holds significance because vengeance typically correlates with adverse physical and psychological health outcomes. We suggest ways to advance research outlined in the special issue, such as assessing cross-cultural invariance and using diverse research designs. Moreover, increasing the diversity of socioeconomic status in studies conducted in the Muslim world and exploring hypotheses in high-income countries are necessary for contextually nuanced research. Overall, this special issue offers valuable insights into the dynamics of forgiveness and vengeance and highlights the role of culture and gender on psychological well-being across diverse contexts.

How HEXACO personality traits are involved in school performance of middle school adolescents (10-14 years).

This paper aimed at investigating the relationship between HEXACO personality traits and academic performance in two samples of Italian 10-14 years old middle-school adolescents (N = 714 and N = 1093) using Multilevel Mixed Models. The main results show that: 1) Conscientiousness and Openness to Experience were the most important predictors of school performance, followed by Honesty-Humility; 2) a modest effect was present also for eXtraversion and Emotionality; 3) these influences occurred net of the influence of gender and class and could be generalized to male and female adolescents across 6th, 7th and 8th grade; 5) Perfectionism, Diligence and Prudence within Conscientiousness, Inquisitiveness within Openness, and Sincerity within Honesty-Humility were the facets more correlated with school performance; 6) results were replicated in two studies. Results are discussed and conclusions are drawn.

A 'Problematic' Pattern of Power-system Functioning and its Association with psychopathological Symptoms.

Following the well-researched two-dimensional model of attachment-system functioning, based on the concepts of hyperactivation and deactivation, a two-dimensional model of the power behavioral system has recently been proposed. The power system is aimed at activating, organizing, and implementing action patterns that protect or restore a sense of power or dominance. Here, we tested predictions derived from the two-dimensional model of power-system functioning regarding the contribution of a 'problematic' high-high pattern, characterized by the coexistence of both hyperactivating and deactivating strategies, to psychopathological symptoms. A non-clinical sample of Italian adults (N = 385) completed the Power Behavioral System Scale together with self-report measures of anxiety and depression symptoms and difficulties in executive control. Multiple regression analyses showed that higher deactivation and hyperactivation scores, characteristic of the 'problematic' pattern, significantly predicted anxiety and depression symptoms as well as executive function difficulties. These results provide initial support for the pathogenic implications of the 'problematic' high-high pattern of power-system functioning.

Development and validation of an instrument to measure personality in adolescence: The HEXACO Medium School Inventory Extended (MSI-E).

In this paper, we aimed at developing and validating a novel instrument to evaluate personality in 10-14 years old adolescents with six basic traits, with two dedicated studies. In Study 1, we generated a large pool of items (384 items) from three basic items sources, which we administered to 714 Italian adolescents. Using principal component analysis (PCA) and extension factor analysis, we selected the best eight items for each facet, and so the best 32 items for each factor, except for the Unconventionality facet of Openness to Experience (O) for which we selected the best six items. This resulted in a total of 190 items. The 190-item HEXACO-MSI had very good levels of dimensional validity and reliability, but it fell short in containing 8 items for each facet (i.e., for Unconventionality) and in balancing normal and reversed items within each facet. Therefore, in a second study we added items to the scale and verified again the dimensionality and reliability with the goal of developing a final version of the scale. In Study 2, we administered a version of the HEXACO-MSI consisting of 219 items to 1175 Italian adolescents. Using principal component analysis (PCA), we selected the best eight items for each facet equally balanced between normal and reversed items within each facet and factor. Confirmatory factor analysis (CFA) confirmed the six-factor structure and its invariance. The results showed that the HEXACO-MSI-E had a clear six-factor structure in adolescents, that was invariant across gender and across the three middle school classes, and was reliable. Finally, we established temporal stability of each factor in two measurements after one year. Together with the positive results of this contribution, we discussed some aspects for future studies.

Specific Global-Local Visual Processing Abilities Mediate the Influence of Non-social Autistic-like Traits on Mental Rotation.

Inconsistent data are available on mental rotation performance in neurotypicals with high autistic-like traits. Here, we tested whether global-local visual processing abilities mediate the influence of specific autistic-like trait domains (social skill, attention switching, attention-to-detail, communication, and imagination) on mental rotation. Neurotypical participants (N = 128) underwent an assessment of autistic-like traits, a flanker task with hierarchical stimuli, and a mental rotation task. Path analysis showed that Reaction Times on the incongruent/local condition of the flanker task mediated the relationship between attention-to-detail and mental rotation accuracy. These findings indicate that a better capacity of ignoring incongruent global information to identify local information (reduced global interference) in persons with high non-social autistic-like traits, as attention-to-detail, facilitates mental rotation performance.

Validation and psychometric properties of the Italian version of the Power Behavioural System Scale.

The power behavioural system is a neurobehavioral system that motivates a person to acquire and control resources that are important for survival and reproductive success. When activated, its function is to protect or restore the sense of power, influence, or dominance. Repeated experiences of failure in achieving this goal may result in hyperactivation or deactivation of power-oriented behaviours (analogous to the secondary strategies observed with respect to the attachment behavioural system). Gaining a reliable and valid measure of hyperactivation and deactivation of the power system can be important for understanding an individual's responses to different social contexts and, in clinical settings, can help the therapist identify the client's difficulties that may undermine the therapeutic process. In the present study, we developed the Italian version of the Power Behavioural System Scale (PBSS), a self-report measure developed by Shaver et al. (2011) to assess individual differences in hyperactivation and deactivation of the power system. Results indicated an adequate fit to the expected two-factor model, and the measure proved to be reliable and had good convergent and structural validity, allowing the quantification of individual differences in power system hyperactivation and deactivation.

Construct and criterion validity of the HEXACO Medium School Inventory Extended (MSI-E).

In this cross-sectional study we aimed at: 1) validating the observer (Obs) version of HEXACO Medium School Inventory Extended (MSI-E); 2) establishing convergent and divergent construct validity of the HEXACO-MSI-E; 3) establishing criterion validity of HEXACO-MSI-E. We administered the HEXACO-MSI-E, the Big Five Questionnaire-Children (BFQ-C), the Internalizing and Externalizing scales of Youth Self Report (YSR), some items of the 2019 Middle School Youth Risk Behavior Survey (YRB) and some items about adolescents' values, beliefs, behaviors, and desired features of a possible future job to 1175 adolescents (Mage = 12.03, SD = 0.89) and the observer version of these measures (except for BFQ-C) to 854 parents or legal guardians. The factorial structure and the reliability of the Observer Report of HEXACO-MSI-E were confirmed. Convergent and divergent validity were successfully established with a version of the inventory filled out by parents. Convergent and divergent validity were also established with BFQ-C notwithstanding some only apparent anomalies. Criterion validity was established with respect to four specific groups of criteria collected in both self-report and observer form. HEXACO-MSI-E traits were more predictive with respect to self-report than to observer criteria and the majority were common. Together with the positive results of this study, implications and issues for future studies are discussed.
