Physiological concomitants of perseverative cognition: a systematic review and meta-Analysis

Rumination about the past and worries about the future (perseverative cognition) are extremely common, although pervasive and distressing, dysfunctional cognitive processes. Perseverative cognition is not only implicated in psychological health, contributing to mood worsening and psychopathology but, due to its ability to elicit prolonged physiological activity, is also considered to play a role in somatic health. Although there is emerging evidence that such negative and persistent thoughts have consequences on the body, this association has not yet been quantified. The aim of this study was to meta-analyze available studies on the physiological concomitants of perseverative cognition in healthy subjects. Separate meta-analyses were performed on each examined physiological parameter. Sixty studies were eligible for the analyses. Associations emerged between perseverative cognition and higher systolic blood pressure (SBP) (g = .45) and diastolic blood pressure (DBP) (g = .51) in experimental studies, and higher heart rate (HR) (g = .28 and g = .20) and cortisol (g = .36 and g = .32), and lower heart rate variability (HRV) (g = .15 and g = .27) in experimental and correlational studies, respectively. Significant moderators were sex, ethnicity, type of induction used to elicit perseverative cognition, assessment of state versus trait perseverative cognition, focus on worry or rumination, duration of physiological assessment, and quality of the studies. With the exception of blood pressure, results were not influenced by publication bias. Results show that perseverative cognition affects cardiovascular, autonomic, and endocrine nervous system activity, suggesting a pathogenic pathway to long-term disease outcomes and clarifying the still unexplained relationship between chronic stress and health vulnerability.

Family functioning and binge drinking among Italian adolescents

Limited studies have sought to describe binge drinking among adolescents and even fewer studies have attempted to examine whether family functioning, family communication and satisfaction could be associated with alcohol abuse. Our sample was made up of 726 Italian adolescents between the ages of 16 and 18. According to previous research, adolescents were categorized into non-drinkers, social, binge and heavy drinkers. Results showed that social, binge and heavy drinkers differ in terms of some drinking variables, family functioning, family communication and satisfaction.

Cognitive rigidity is mirrored by autonomic inflexibility in daily life perseverative cognition.

Mind wandering (MW) can be persistent and therefore has been included in the repetitive thinking conceptualization. In line with a dimensional view of psychopathology, we hypothesized the existence of a MW-Perseverative Cognition (PC) continuum, where the latter is characterized by a rigid and defensive pattern with attentional, behavioral, affective, and autonomic perseverative manifestations. Ambulatory heart rate (HR) and variability (HRV) of 42 participants were recorded for 24h. Approximately every 30 min during waking, subjects reported their ongoing thoughts and moods using electronic diaries. MW was characterized by less effort to inhibit the thought and less interference with ongoing activities, absence of mood worsening, and higher HRV compared to PC. Worse sleep quality was predicted by higher levels of trait rumination and daily PC. Results suggest that MW and PC represent the functional and pathological ends of a continuum, respectively.

Binge eating and binge drinking behaviors: Individual differences in adolescents’ identity styles

Considering the significant negative consequences that are directly related to binge eating and drinking behaviors, many studies have explored the reasons why adolescents engage in them. This study examined the differences in the development, maintenance, and co-occurrence of “binge” behaviors associated with adolescent’s identity style and the level of commitment. One thousand four hundred Italian adolescents completed self-report measures assessing binge behaviors and identity styles. Overall, results show that diffused adolescents were more likely to be engaged in binge eating and binge drinking behaviors than others, validating the idea that the achievement of a consolidated ego identity is important for enhancing well-being.

Suicidal Ideation among Italian and Spanish Young Adults: The Role of Sexual Orientation

The purpose of the current study was to identify demographic, social, and psychological variables associated with suicidal ideation in an Italian sample and a Spanish sample, taking into account the relevance of sexual orientation as a risk factor for suicide. Three hundred twenty gay and bisexual men, 396 heterosexual men, 281 lesbians and bisexual women, and 835 heterosexual women were recruited. In chi-square and multivariable logistic regression analyses we identified several consistent cross-national risk factors for suicidal ideation: having lower education, not being religious, being homosexual or bisexual, not being engaged in a stable relationship, having lower level of peer and parental attachment, and having depressive symptoms. Interestingly, the strongest risk factor in both samples, after depression symptoms, was sexual orientation.

The role of parenting styles and alcohol expectancies in teen binge drinking: A preliminary investigation among Italian adolescents and their parents

As adolescents’ alcohol abuse is more widespread almost everywhere, the aim of this study was to better understand the influence of both alcohol expectancies and parenting styles on this risky behaviour in order to allow the development of future prevention programmes, by evaluating the correlation between these variables. A total of 1500 subjects participated in this study: 500 high school students were asked to complete different questionnaires concerning their consumption attitude, and their beliefs on alcohol, whereas their parents (N = 1000) were asked to evaluate parenting styles. According to previous studies, the sample was classified into non-drinkers, social, binge and heavy drinkers. Consistent with the hypothesis, statistical analysis showed that both alcohol expectancies and parenting style significantly differ within these groups, thus being powerful predictors of high-risk drinking patterns.

The Role of Nice and Nasty Theory of Mind in Teacher-Selected Peer Models for Adolescents with Autism Spectrum Disorders.

The study aimed at verifying if nice and nasty theory of mind behaviors, in association with teachers’ peer buddy nomination, could be used to correctly select peer models for adolescents with autism spectrum disorder. Mentalizing abilities and emotional and behavioral characteristics of 601 adolescents were assessed. Results suggest that teachers recognize how students socially use their mind-reading ability, and employ such knowledge to select peers as intervention agents.

Re-enactment of intended acts from a video presentation by 18- and 24-month-old children

We used the Re-enactment of intention paradigm to investigate whether children would re-enact what an adult intended to do in a video presentation as they do when presented with a live demonstration (Meltzoff in Dev Psychol 31(5):838–850, 1995). Unlike the 18-month-old infants studied by Meltzoff (Dev Psychol 31(5):838–850, 1995), the 18- and 24-month-olds in the current study did not frequently imitate unsuccessful goal-directed actions presented in a video model. Children who performed better in the task also tended to share more of their attention with the experimenter during co-viewing of the video. Performance on the Re-enactment of intention task was positively related to categorization score, an independent measure of cognitive functioning.

Hemodynamic Profiles of Functional and Dysfunctional Forms of Repetitive Thinking

BackgroundThe ability of the human brain to escape the here and now (mind wandering) can take functional (problem solving) and dysfunctional (perseverative cognition) routes. Although it has been proposed that only the latter may act as a mediator of the relationship between stress and cardiovascular disease, both functional and dysfunctional forms of repetitive thinking have been associated with blood pressure (BP) reactivity of the same magnitude. However, a similar BP reactivity may be caused by different physiological determinants, which may differ in their risk for cardiovascular pathology.PurposeTo examine the way (hemodynamic profile) and the extent (compensation deficit) to which total peripheral resistance and cardiac output compensate for each other in determining BP reactivity during functional and dysfunctional types of repetitive thinking.MethodsFifty-six healthy participants randomly underwent a perseverative cognition, a mind wandering, and a problem solving induction, each followed by a 5-min recovery period while their cardiovascular parameters were continuously monitored.ResultsPerseverative cognition and problem solving (but not mind wandering) elicited BP increases of similar magnitude. However, perseverative cognition was characterized by a more vascular (versus myocardial) profile compared to mind wandering and problem solving. As a consequence, BP recovery was impaired after perseverative cognition compared to the other two conditions.ConclusionsGiven that high vascular resistance and delayed recovery are the hallmarks of hypertension the results suggest a potential mechanism through which perseverative cognition may act as a mediator in the relationship between stress and risk for developing precursors to cardiovascular disease.

Peer and Teacher-Selected Peer Buddies for Adolescents With Autism Spectrum Disorders: The Role of Social, Emotional, and Mentalizing Abilities

ABSTRACT This study examined mentalizing abilities, social behavior, and social impact of adolescents who expressed the willingness to become peer buddies for adolescents with Autism Spectrum Disorders, and adolescents selected by their teachers and peers. Twenty-seven teachers and 395 adolescents from public high schools completed mentalizing abilities, social status, behavioral, and peer buddy nomination measures. Findings suggest that social status and preference play a significant role in the selection of peer buddies by both teachers and classmates. Furthermore, more advanced Theory of Mind (ToM) abilities and the engagement in prosocial behaviors differentiated peers selected as buddies from other classmates. When compared with nonparticipating students, adolescents who expressed willingness to participate were more often girls, and were more prosocial. Agreement between teacher and peer nominations of best peer was moderate.
